0002Earth drilling devices are regularly operated by a user who is positioned in a driver's cab, usually an operator's cab. A seat for an operator is arranged in the driver's cab and the operator can control the operation of the earth drilling device by means of at least one actuating element, in particular a multifunction joystick.

It is described that the function of drilling by means of the earth drilling device is enabled even when there is no user in the cabin.

0006The object of the invention is therefore to create a system, a method and a use with which the effort for making the hole by means of the earth boring device can be reduced, in particular the effort in the form of providing a smaller number of operating and control units / or supervisors, with an increased safety function of the earth drilling device also being given.

0007The object is achieved by the subjects of the independent claims. Advantageous embodiments are the subject of the respective subclaims and the description.

0008The core idea of ​​the invention is to design an input device, which is provided for entering at least one parameter for the operation of the earth drilling device, as a remote control. The configuration of the input device as a remote control creates the possibility that the operator previously provided in the driver's cab can choose their location more freely with regard to the control of the earth boring device. The operator no longer necessarily has to stay in the driver's cab to control the auger. Due to the free possible placement of the operator, they can be present at other possible locations when controlling the earth boring device and thus at the same time while controlling the earth boring device at a place where previously another operator had to be present to carry out an activity in connection with the insertion to carry out or monitor the earth drilling in the ground. Since the activity can now also be carried out by the operator who is otherwise present in the driver's cab, the additional operator can be omitted. The previously required additional operator can be entrusted with other tasks, so that the personnel and / or the costs for providing the personnel for the introduction of an earth drilling device can be reduced. An additional benefit for the company using the earth auger is possible.

0009The invention provides a system which comprises an auger device with a control device for operating the auger device. The system also has an input device, which is functionally coupled to the control device, for inputting at least one parameter for the operation of the earth boring device. In particular, the parameter can cause drilling to be started with the auger device or to stop a drilling carried out with the auger device. The input device is designed as a remote control.

0010A capacitive or mechanically operable actuating element and / or a radio transmitter is provided on the input device in order to determine whether the operator entrusted with the operation of the earth drilling device is holding the input device or grasping it with their hands. In this respect, an actuating element and / or a radio transmitter is provided with which it can be determined whether an operator can operate the input device or is in their immediate vicinity. A capacitive or mechanically operated actuating element can detect the presence of the operator just like a radio transmitter. In the case of a mechanically actuatable actuating element, it can be determined, for example, whether the operator actuates the respective actuating element in order to allow inputs and / or further work of the earth boring device and not to transfer it into a protected state. It can be provided, for example, that a parameter is only entered when the respective actuating element has positively recognized that the operator is holding the input device or grasping it with his hands or is actuating the actuating element at the same time. This makes it possible to determine whether, for example, the operator has put the input device to one side in order to, for example, work on the auger or not. to access these with the auger still drilling a ground and driving the drill string. In such a case, the earth boring device can be switched off or transferred to a state of rest. In such a case, the input device can transmit to the control device a signal corresponding to a parameter which, in a real instruction, can mean “force idle state” or “emergency shutdown”. It can be provided that the "idle state" of the earth drilling device differs from the state of the earth drilling device after an "emergency shutdown"; in the case of an "emergency shutdown", the earth drilling device can be switched off, whereas in an "idle state" the units and / or drives of the earth drilling device continue to be switched on but remain switched off without a drive.

0011For the purposes of the description, an "earth boring device" is any device which moves in particular a drill pipe with rod sections in an existing or to be created channel in the ground in order to create or widen a bore, in particular a horizontal bore (HD), or pipelines or other long bodies to move into the ground. The earth drilling device can in particular be a high-pressure device. The term “HD” (horizontal drilling) in the context of the present description includes in particular an at least partially horizontally arranged bore or channel or pipeline. An earth boring device can thus be a device driving a drill pipe, which works by displacing the earth and introduces the drill pipe into the earth in a translatory and / or rotary manner in the longitudinal axial direction of the drill pipe. A borehole can be drilled into the ground by applying tension or pressure to the drill pipe. In the context of the description, the term “rod section” does not exclusively include rigid, individual force transmission elements which can be connected directly or indirectly to one another and which can be used in an earth boring device.

0012A front section of the drill string can be designed as a drill head or drill tool. Furthermore, the drill rod can have a probe housing, in particular in a front area.

0013The term “control device” in the sense of the description comprises an embodiment of a control by means of which a directional influencing of the earth drilling device during operation, ie during the implementation or for starting or stopping an earth drilling, is possible. The control device can in particular be designed electrically or electronically. The parameters entered by the operator can be used by the control device - optionally converted and / or processed into electrical signals - as inputs for the operation of the earth boring device. The earth boring device can thus be operated or controlled by means of an input of a parameter which, if necessary, has been converted into an electrical signal.

0014A "parameter" in the sense of the description is understood to be an input with which a directed influencing of the operation of the earth boring device is possible. The parameter can be transmitted as an input signal to the control device, by means of which the control device controls the operation of the earth boring device. A parameter can, for example, cause drilling to be started with the auger device or a stop of a drilling carried out with the auger device. It is possible, for example, for an operator to enter the "Start" parameter and an input signal linked to the input to be transmitted to the control device, which causes the drilling to be started. In an analogous manner, an operator can enter the parameter “stop” and a corresponding input signal connected to this can be transmitted to the control device, which causes a stop of a drilling carried out with the earth boring device. Further parameters that influence or change the operation of the earth boring device are possible, these parameters being able to be entered by an operator and converted by the input device into an input signal and transmitted to the control device.

0015The term "input device" in the sense of the description includes any electrical or electronic device that is suitable for converting an input from an operator into an electrical signal that can be processed without further processing or with the interposition of processing of the signal, in particular processing in an or several circuits, for example in an amplifier, can be transmitted to the control device in order to be used as input or to serve as an input signal of the control device. The input device can be understood as an interface between an operator and the control device. The input device can have a portable power supply, in particular in the form of one or more batteries, accumulators or the like.

0016The input device can in particular have a processor, which is designed as an arithmetic unit with electronic circuits in order to execute commands. The processor can be programmed and is designed to process commands. The input device can have an operating system which can be modified, for example, for an improvement and / or adaptation to changes in an earth drilling device. A change in the operating system can in particular only be allowed if a password and / or the input device is connected to an interface of a computer, a dongle or the like. In particular, the processor can recognize, query, process, forward inputs from an operator in the form of the parameters and / or process further commands of a program. The processor can run a program that queries or receives inputs from an operator, processes the operator's inputs, sets settings for the operator's input, transmits the inputs to the control device and / or receives, processes and / or implements signals from the control device.

0017The term "functionally coupled" in the sense of the description includes a, in particular unidirectional or bidirectional, connection of the devices mentioned, in particular to provide signals from one of the devices, in particular the input device, and to receive and / or receive them with the other device, in particular the control device process received signals. The functional coupling can take place directly or indirectly through the interposition of further elements or devices.

0018A "remote control" in the sense of the description comprises an electric or electronic hand-held device which is suitable for controlling the operation of the earth drilling device by means of the input of a parameter at a distance from the earth drilling device. For the purposes of the description, “at a distance from the earth boring device” is to be understood in such a way that direct input by means of a device attached to the earth boring device is not necessary. In particular, an operator outside the driver's cab of the auger device can control the operation of the auger device by entering a parameter for the operation of the auger device.

0019In a preferred embodiment, the input of the at least one parameter (a) is a setting of a or a torque and / or speed applied to a drill pipe of the auger, (b) setting a linear feed force and / or linear feed speed applied to a drill pipe, (c) setting an impact frequency of a percussion piston, (d) setting an impact amplitude of a percussion piston , (e) setting a flow rate and / or pressurization of a flushing liquid, (f) carrying out a linkage change, (g) performing a rod lubrication and / or (h) changing a drill head type. It can be taken into account which linkage is involved. In particular in the case of a double pipe rod, the torque and / or the speed can be selected independently for an inner pipe rod, so that for a double pipe rod, both the torque and / or the rotational speed for the inner pipe rod and / or the outer pipe rod can be set. In this way, essentially any input can be made that may be relevant for the drilling operation of the earth drilling device. In addition to starting or stopping a drilling carried out with the earth drilling device, the aforementioned parameters can be transmitted to the control device.

0020For setting a torque / speed applied to the drill pipe in the earth drilling direction, the control device can transmit a signal to the drive of the earth drilling device which is connected to the drill pipe, depending on the parameters entered by the operator using the input device, so that the torque / speed selected by the operator can be set. The parameter can be a signal that corresponds to the magnitude of the torque / speed. The setting of a linear advance of the drill pipe can be used to set both the force or the pressure and / or speed with which the drive acts on the drill pipe connected to the drive. The setting of the linear feed can also include whether the linear feed is a tensile or compressive force, that is to say whether the drill pipe is pulled or pushed through the earth. In this respect, the term feed includes both directions, both pulling and pushing the drill string, so that a pulling or pushing force can be applied to the drill string. The parameter can thus be a signal that corresponds to the tensile or compressive force. When drilling a hole in the ground, flushing liquid, in particular in the form of bentonite, can be used. The flushing liquid can be passed through the drill pipe and exit in the front area of ​​the drill pipe. A flow rate / pressure of the flushing liquid can be set as a parameter, which can be adapted to the conditions in the ground. When drilling with a drill rod, it is necessary in the course of the earth drilling to lengthen the drill rod, in which case, in particular, further rod sections are connected to the drill rods that have already been drilled in the ground. To this end, an input may be required that carries out a rod change, ie the connection of a further rod section, in particular from a rod magazine, with the drill rod that has already been drilled. The parameter can thus be an actuation that corresponds to the command "Now rod change". When changing the rods, the drill rods that have already been drilled into the ground can be clamped in order to fix the axial and / or angular position of the drill rods that have already been drilled. Furthermore, entering the parameter can include changing the type of drilling head, which can be necessary in particular if, after a pilot drilling has been carried out, ie a first hole, which was created, for example, by pushing in the ground, the drill head type is changed to an expansion drill head, which is pulled through the previously generated pilot hole to expand the same.

0021If the earth boring device is designed as a ram drilling device, the impact frequency of the percussion piston of the ram drilling device and / or the impact amplitude of the percussion piston of the ram drilling device can be set. The term "ram boring device" or "earth rocket", which is essentially used synonymously with the term ram boring device, includes, in the sense of the description, a self-propelled impact device which works by displacing the soil and can drive a line or pipe into the ground by striking it. The term ram boring device can include earth boring devices in which the drill head tip is arranged in a housing so that it can move longitudinally. The drill head tip can in particular be a chisel. A ram boring device can be both a single-stroke device and a multi-stroke device. With a one-stroke device, the percussion piston hits the drill head tip and at the same time hits the housing. In the case of a multi-cycle device, in particular a two-cycle device, the percussion piston first hits the drill head tip, which thus runs ahead in the first cycle. The housing is acted upon by the percussion piston in a subsequent cycle, in particular in a second cycle. In the case of a multi-cycle device, the tip resistance and skin friction can be separated from one another and thus more easily overcome.

0022In a preferred embodiment, the input device has at least one mechanically actuatable actuating element. The mechanically actuatable actuating element can be any mechanically or manually actuatable actuating element. A rotary actuator, a control stick and / or a push button are preferred embodiments of a mechanically actuatable actuating element. Different types of actuation elements are possible on the input device. Several actuating elements of the same type can be provided on the input device.

0023In the context of the description, a control stick is an actuating element for inputting two-dimensional signals in particular. A control stick can have an element that extends from a surface and can generally be tilted in several directions. The element can in particular be designed in the shape of a rod, a stamp, a stick or a lever. The element can extend from an area at a height which does not exceed 7 cm, preferably 6 cm, preferably 5 cm, preferably 4 cm, preferably 3 cm, preferably 2 cm, preferably 1 cm. The diameter of the element can in particular be less than 5 cm, preferably 4 cm, preferably 3 cm, preferably 2 cm. A control stick in the sense of the description can also be referred to as an analog stick or joystick and can be equivalent to this in terms of its function. The term control stick also includes a control pad with which two-dimensional signals can be entered. With the control stick, a signal can be generated which is dependent on the position of the element or the control cross in relation to a standard or rest position of the element or the control cross. It can be provided that the control stick delivers individual electrical signals when actuated and / or continuously delivers an electrical signal in the form of voltages and / or currents, with a potentiometer for one of the dimensions in which the element or the control pad can be tilted is, can be used; for example a potentiometer for the top / bottom position and a potentiometer for the left / right position. By changing the position or The position of the element or the control pad of the control stick in relation to the rest or standard position can change the voltage. The size and / or arrangement of the control stick on the input device can be designed in such a way that it can be actuated by an operator using a thumb and / or finger; in particular, the control stick can be actuated without closing the control stick encompass. If it is implemented that the control stick is designed to generate signals as a function of a movement in at least two dimensions, this also includes the possibility that an input can be provided for controlling the operation of the earth drilling device by means of a control stick , in which the control stick does not generate any signals with regard to the movement in one of the dimensions and / or signals with regard to the movement in one of the dimensions are not or do not have to be taken into account by the control device.

0024A rotary actuator or rotary knob in the sense of the description can have a potentiometer or be formed by this. Advantageously, the rotary actuators are essentially maintenance-free and insensitive to vibrations; furthermore, turning the turntable in the switched-off state may have no effect.

0025A push button in the sense of the description is an actuating element which can be designed as an assembly that establishes or disconnects an electrically conductive connection. The push button can be designed as a toggle switch or as a simple push button switch. It has been found that it is advantageous that an actuation stroke of a push button should be at least more than 2 mm in order to be considered an "intended" actuation. Actuation strokes of more than 2.3 mm are preferred, with gloves also being able to provide actuation strokes of more than 3 mm, preferably more than 5 mm, particularly preferably more than 6 mm, even more preferably more than 7 mm. For the diameter of a push button, it has proven to be advantageous that the diameter of the push button should be more than 5 mm, in particular more than 7 mm, for actuation by means of an operator's finger. When operated by an operator's thumb, the diameter of a push button can advantageously be more than 15 mm, preferably more than 17.5 mm, in particular more than 20 mm.

0026A selection of mechanically operable actuating elements can be provided on the input device. In particular, actuating elements that are customary in the prior art can be used to allow the operator the otherwise customary input option for controlling the earth boring device. The size and / or arrangement of the actuating elements can vary compared to the prior art; in particular, a control stick on the input device can be designed to be smaller than a multifunctional joystick arranged in the driver's cab.

0027In a preferred embodiment, at least one mechanically operable actuating element, in particular a control stick, is arranged as an exchangeable unit in a receiving space of the input device. In this way, the possibility can be created that an actuating element required for the operation of the earth boring device can be exchanged quickly in order to enable the operator to operate the earth boring device as continuously as possible. Such a simple exchange can be advantageous due to the operation of the input device outside the driver's cab, since the actuating element can be exposed to greater wear.

0028In a preferred embodiment, the sensitivity of the mechanically actuatable actuating element can be set (a) mechanically and / or (b) by means of software that is functionally coupled to the actuating element by means of a sensor and a counter-element. This makes it possible for an operator to set the sensitivity, in particular of a control stick or a rotary actuator, even under different conditions, for example with or without gloves. For example, two different settings are possible for the sensitivity of an operating element: 1) Operation is carried out with a glove or 2) Operation is carried out without a glove. It can also be provided that the sensitivity can be set as a function of the type of input or the parameter. The setting can be made by the processor in the input device.

0029In a preferred embodiment, the input device has at least one, in particular two, mechanically operable actuating elements, in particular one or two pushbuttons, which are at least so spaced from one another on the input device that two-handed actuation is required. In this way, a so-called dead man's device can be created with which it can be checked whether an operator is present or able to act. If it is recognized that an actuation of one of the actuating elements does not take place, it can be concluded from this that the operator is not present and / or unable to act, as a result of which a signal or a switching action can be triggered. In this way, an increased degree of safety can be achieved in the operation of the earth boring device. For example, an operator can be prompted by means of a haptic signal, a visual display and / or an acoustic signal to actuate the actuating element (s); if it is not actuated, a signal or a switching action can be triggered that puts the earth boring device into an idle state or (emergency) switches it off. The provision of two mechanically operable actuating elements, of which only one has to be used as a so-called dead man's device, can provide the advantage that - provided the mechanically actuable actuating elements are provided on the right as well as on the left of the input device - the input device can be used both by right-handers can also be operated ergonomically by left-handed operators. It can therefore be sufficient that a dead man's device is configured either on the left or on the right. However, the provision of the two options both on the right and on the left takes into account the possible requirements of the operator.

0030In a particularly preferred embodiment, a monitoring device, which can be designed as part of the processor, is present. The monitoring device is designed to check the actuation of two actuating elements for simultaneity. Additionally or alternatively, it can be provided that it is further monitored that the actuating elements actuated at the same time are not actuated again within a predetermined time window. With the help of the monitoring device, a time difference with regard to the "simultaneity" of the triggering of the two actuating elements can be set in the form of a tolerance. If necessary, the time after which the actuating elements must be released again can also be set. A simple design of a dead man's device is possible.

0031The input device can have a circumferential outer contour, in particular an interrupted or closed, which can envelop an inner contour or an interior of the input device. The circumferential outer contour can be essentially rectangular, square, polygonal, round, circular and / or elliptical over the entire area or only in sections. Mixed forms and combinations of the aforementioned forms are possible. In particular, it can be provided that the input device is essentially rectangular or cuboid and has a dimension in the range of 15 cm to 50 cm in width, preferably 20 cm to 40 cm in width, 10 cm to 30 cm in length , preferably 15 cm to 25 cm in length, and 3 cm to 15 cm in height, preferably 5 cm to 10 cm in height.

0032It can be provided that the input device has at least one projection or several projections, in particular two, in particular with regard to one of the aforementioned shapes, which can be configured for grasping by means of the operator's hands, in particular the projection or projections can be configured like a handle. A handle-like configuration that can be gripped by the operator's hand can be preferred. The protrusion or protrusions can protrude from the rectangular, square, polygonal, round, circular and / or elliptical shape of the input device. The mechanically actuatable actuating elements can in particular be formed on one or each of the projections. The projections can be formed on the input device in such a way that a surface facing the operator is located by means of the projection or the projections results, which gives a surface that can in particular lie in a plane. It can be provided that the projections protrude on a surface with an above-mentioned shape, in particular to form a receptacle, in particular having the circumferential outer contour, for a display device described below in the description in its entirety or in sections. The protrusion or protrusions can protrude from a base surface or a base plate. The projection or projections can form, at least in sections, an edge on a base plate which forms the above-mentioned shape. The projection or projections can be offset to the front with respect to the base plate. If there are several projections, the projections can project in the same direction with respect to a base surface or base plate and form an edge on this. The base plate with the projection or the projections can in particular reproduce an outer circumferential contour of a display device in sections. The base plate can be completely closed or have openings. At the edge of the base plate, a wall can protrude at least partially or in a closed manner, which wall can surround a display device described below in the description, at least in sections or completely on the circumferential side.

0033A curved adaptation of the projections to the shape of the operator's hands is possible, which relates in particular to the corners of a projection. The respective projection can be adapted to the dimensions of an operator's hand; As a result, the input device can be designed in the other areas independently of the dimensions of the operator's hands; it is possible that there is an adaptation to the dimensions and shape of the hands only in the area of ​​the projections. An adaptation to the shape and / or dimensions of the operator's hands, which can mean a reduction in the structural shape, can thus only be related to the projections.

0034The said protrusion or protrusions can have a diameter in the range of 3 cm to 5 cm, preferably 3 cm to 4 cm, for good grip by an operator. The length of a projection can be designed to be greater than 10 cm, preferably greater than 15 cm, for good, in particular fatigue-free, holding by means of an operator's hand, in order to also take into account, for example, that the operator is wearing a glove.

0035If more than one projection is formed on the input device, the projections can be configured on opposite sides of the input device. A mirror-symmetrical arrangement of the projections is possible. The mechanically actuatable actuating elements can be designed mirror-symmetrically to one another when a plurality of projections are provided on the projections.

0036If the respective projection is gripped by the hand of the operator provided for it, a control stick can be arranged on the projection in the area of ​​the thumb. A control stick is preferably arranged in the area of ​​the thumb on each of the projections. A mechanically actuatable actuating element embodied as a control stick preferably rises from an essentially flat or non-curved surface. The control stick can rise from a surface of the input device facing the operator. In particular, a control stick can rise from a surface that is parallel to the base surface of the input device, which can essentially be defined by the outer circumferential contour.

0037If a control stick is provided on the input device, a further mechanically actuatable actuating element, in particular a rotary actuator, can be arranged on a surface of the projection that is different from the surface for the control stick. Independently of the provision of a control stick, a rotary actuator can in particular be arranged on a surface of the projection that extends away from the operator. The surface on which a rotary actuator is arranged can, in particular, enclose an angle of 10 ° to 60 °, preferably 20 °, with a surface that faces the operator when holding the input device or on which a control stick is provided up to 50 °, includes. The turntable can in particular be arranged in such a way that it can be operated easily by an index finger or middle finger of the operator while holding the input device, in particular when the operator grips the possibly provided projection on the input device.

0038If a control stick is provided on the input device, a push button in particular can be arranged on a different surface provided for the control stick. A push button can in particular be arranged on a surface of the projection which extends away from the operator when the input device is held. The surface on which the push button can be provided can, if a control stick is provided, lie opposite the surface from which the control stick rises. The surface on which a push button is arranged can, in particular, enclose an angle with a surface on which a control stick is provided, which includes 10 ° to 60 °, preferably 20 ° to 50 °. The push button can in particular be arranged in such a way that it can be easily actuated by an operator's index finger, middle finger or ring finger when the operator is holding the input device, in particular when the operator grabs the possibly provided projection.

0039It can be provided that a push button and a rotary actuator can be present on the same surface at a distance from one another, in particular actuation with different fingers of an operator being possible.

0040Essentially three surfaces can be formed on a projection of the input device, on each of which at least one mechanically actuatable actuating element is arranged. The surfaces on which a mechanically actuatable actuating element is provided can enclose an angle with one another. The surfaces can have a curvature. A mechanically operable actuating element designed as a turntable can preferably be arranged on a surface having a curvature, wherein the curvature of the surface can essentially correspond to the curvature of the turntable, so that in particular an actuation of the turntable can take place over an angular range that is greater than 180 ° , greater than 190 °, greater than 200 °, greater than 210 °, greater than 220 °, greater than 230 °, greater than 240 °, greater than 250 °, greater than 260 °, is greater than 270 °, greater than 280 °, greater than 290 °, greater than 300 °. An operation of a rotary actuator can thus also be carried out easily by an operator who can wear gloves.

0041A mechanically actuatable actuating element designed as a push button can preferably be arranged on a surface having a curvature. A push button can have a curvature that essentially corresponds to the curvature of the surface. It can be provided that the push button can be actuated over a larger angular range, which can correspond to the angular range of the curvature. An actuation can take place even if the pushbutton is not actuated in a straight line.

0042A structuring of the input device for at least partial or complete inclusion of a further device, in particular a display device described below in the description, is possible, with an inclusion in the sense of the description relating to a possibility of a connection between the two devices, in particular the input device and the display device, which in particular can be positively and / or non-positively.

0043In a preferred embodiment, the input device has a, not necessarily flat, surface on which at least two actuating elements are arranged in the area of ​​two adjacent corners and / or opposite edges. The corners and / or edges can also be formed on one or more projections. This enables two actuating elements to be arranged in an ergonomically favorable manner for the operator. The principles of an optimal adaptation can thus be satisfied. Occupational medical, user-friendly or ergonomic or body-appropriate configurations can be taken into account for the operator.

0044In a particularly preferred embodiment, the input device can be gripped around by one hand of an operator in the area of ​​the corners and / or the edges - possibly in the area of ​​a projection. Furthermore, in the preferred embodiment, at least one actuating element can be arranged in the area of ​​the corners and / or the edges - possibly on one or more projections - in such a way that it can be reached by a finger or thumb of the user when reaching around the corners and / or the edges is. It has been found here that an optimal adaptation is met from an ergonomic point of view, which also includes occupational medical and ergonomic and user-friendly criteria. For example, the thickness of the corners and / or edges of the input device can be adapted to the hand of an operator, it being possible to take into account that the operator is wearing gloves or not wearing gloves.

0045In particular, the actuating elements which are arranged in the area of ​​the corners and / or the edges can be control sticks. In particular, the control sticks can be arranged on a surface of the input device which forms a base surface or is arranged offset parallel to it.

0046In a preferred embodiment, the input device is designed as (a) wired and / or (b) wireless remote control. In a particularly preferred embodiment, the input device is a wireless remote control, which makes it possible for the operator to move essentially freely with the input device without having to pay attention to a cable with which the input device is connected to the earth drilling device. A wired remote control offers the advantage of essentially undisturbed transmission of signals via the cable.

0047In a preferred embodiment, the input device is designed to use one or more radio bands for communication with the control device of the earth drilling device. For the purposes of the description, a frequency band denotes frequency ranges, thus partial ranges of the electromagnetic spectrum of the electromagnetic waves used for technical communication. Classifications according to frequency, wavelength or use are common. Different designations of the frequency bands, especially international ones, are possible.

0048In a preferred embodiment, the input device has one or more antennas in order to provide signal paths, in particular in one direction, in order, for example, to increase the safety during the operation of the earth drilling device. It can be provided that a bidirectional transmission of signals between the input device and the control device is possible by means of an antenna. However, it can also be provided that at least one antenna each is provided for one direction (from the input device to the control device and from the control device to the input device) and different antennas are used for the two directions. The antenna (s) can be connected to the processor of the input device.

0049A bidirectional communication between the input device and the control device is possible. For example, the control device can confirm that a parameter has been entered or transmit to the input device that an error has occurred during the input and / or transfer to the control device.

0050In a preferred embodiment, the auger device has one, two or more antennas for communication with the input device. By means of the control device, the earth boring device can in particular use the signal which is the strongest, best or most stable.

0051In a preferred embodiment, the input device has a status display for displaying a status. The status display can be connected to the processor. The status display can relate to a state with regard to a power supply to the input device, a transmission of data and / or signals from the input device to the control device, a signal strength, an indication that the input device is switched on or off, and / or an error message. The status display can be reduced to essential information, so that, for example, a display only takes place when a certain - for example critical - state is reached. For example, the status display can be designed in such a way that a reduced energy supply or an energy supply of the input device that will be running low in the near future has been recognized. As an alternative or in addition, it can be provided that the status display indicates that an error has occurred when data was transmitted from the input device to the control device. Alternatively or additionally, the status display can indicate that the signals generated by an actuating element are incorrect. As an alternative or in addition, the status display can show that the earth auger resp. the control device has detected an error, in particular in the form of a signal from a device monitoring a critical state. The status display can be a plain text display, a simple light source, in particular an LED, which can be designed in color. In the case of a simple illuminant, the color of the illuminant can correspond to the state that is to be displayed to the operator. For example, the color can change or a differently colored light source can be controlled or made to light up if the type of state or the state changes. For example, it can be provided that when the earth drilling device is in operation and no fault has been detected, a green light source is used. If the state changes in the sense of deterioration, for example the energy supply has decreased below a certain level in terms of capacity, then the color orange can be used. A further reduction or an error can be signaled with the color red. In the area of ​​the status display or as part of the status display, a symbol can be arranged or displayed, in particular in the form of an imprint, which indicates or indicates which notice relates to the status display. For example, a battery or rechargeable battery symbol can be used for the status display relating to a power supply. An antenna symbol can be used to display the status of a transmission error.

0052In a preferred embodiment, there is at least one protective elevation for at least one mechanically operable actuating element, the extent of the protective elevation transversely to the surface on which the actuating element is arranged is equal to or greater than the extent of the actuating element transversely to the surface. For example, a protective elevation can have the same or greater extent than the element of a control stick. This makes it possible to prevent unintentional actuation of the actuating element, a relatively simple mechanical structure being sufficient. The protective elevation can, for example, prevent an input device falling to the floor from coming into contact with the floor in such a way that the actuation element is actuated due to the action of the surface of the floor. In addition to the aforementioned spatial extension, the protective elevation can be arranged in relation to the mechanically actuatable actuating element in such a way that unintentional actuation is largely excluded. It can be preferred here that the protective elevation is arranged in spatial proximity to the mechanically actuatable actuating element. The protective elevation can extend in several directions around the mechanically actuatable actuating element. The protective elevation can be present between an outer edge of the input device and the mechanically actuatable actuating element. The protective elevation can form a wall, at least in sections, interrupted or closed, between the edge of the input device and the mechanically actuatable actuating element. The wall can extend in two directions with respect to two different edges of the input device. It is also possible to have more than two walls, which can encircle or enclose the mechanically actuatable actuating element at least in sections, provided that mechanical access by the operator is given.

0053In a preferred embodiment, the input device has a mechanically solid structure which is adapted to the section of a human body of an operator, in particular a finger of an operator. In this way, an input device can be created which is adapted under occupational medical, user-friendly and / or body-appropriate criteria, which in particular can enable fatigue-free holding without tensing the hands.

0054In a preferred embodiment, the input device has a connection for a carrying strap of an operator, as a result of which the operator is relieved of the burden of holding the weight of the input device. Fatigue-free, more pleasant work is possible. It can also be provided that the connection by means of a carrying strap can be used to carry the input device. The operator can let go of the input device and the input device is still attached to the operator, for example on a shoulder strap, neck strap or hip belt.

0055In a preferred embodiment, the input device has one element of a connection pair which can interact mechanically and / or electrically with a further element of the connection pair which is arranged or formed on the earth boring device. The connection pair can be a pair of elements for forming a mechanical and / or electrical connection. The input device can be held securely on the auger device by means of the mechanical connection. Signal transmission and / or energy transmission can be possible, for example, by means of an electrical connection. A rechargeable battery or the power supply of the input device can be charged. The further element of the connection pair can in particular be present in the driver's cab on the earth boring device. By means of the further element of the connection pair in the driver's cab, the possibility can be created of using the input device at a fixed, predetermined location of the earth drilling device that is familiar to the operator and in which the operator is essentially protected from environmental influences.

0056In a preferred embodiment, the earth drilling device has a control stick that is larger than a control stick on the input device. As a result, the previous input option can be retained for the operator using a multifunction joystick known to him by means of the control stick. In particular in the driver's cab, the operator can find a control stick that has been customary up to now - larger than the input device. The earth boring device can be operated in the driver's cab in the usual manner.

0057In a preferred embodiment, a display device is provided for displaying at least one parameter for the operation of the earth boring device, the display device being designed such that it can optionally be mechanically connected to the input device and / or the display device can be mechanically connected to a coupling to the earth boring device can. On the one hand, it can thus be possible for the display device to form a jointly manageable unit with the input device, which can be held by an operator. On the other hand, it is possible that the display device can be connected to the earth drilling device and the input device is in turn connected to the display device, whereby the input device can be indirectly mechanically connected to the earth drilling device. The operation of the earth drilling device can be visualized by means of the display device. The display device can in particular be an electrical or electronic display, which can be configured in particular as a liquid crystal display (LCD), light-emitting diode (LED) matrix display, fluorescent display (VFD) or the like. In particular, an image display that is particularly intuitively understandable can be possible with the display device. The display device can be designed as a universal display instrument in the form of a screen, monitor, display, tablet, notepad, IPAD, smartphone or smart display. In addition to the input device, the display device can be used to visualize the operation of the earth drilling device with regard to at least one parameter that the operator can carry with him on site.

0058In a preferred embodiment, all of the aforementioned parameters for the operation of the earth drilling device can be called up and / or displayed by means of the display device. The display can be designed so that not all parameters are displayed at the same time, but depending on the input of the operator, one or more parameters are displayed that the operator can select for the display or that of a command sequence of the control device for implementation and / or Entering a parameter is considered important and / or necessary. Thus, the display device can be coupled to the input device in such a way that - if the operator wishes to enter a parameter by means of the input device - parameters, data, information and / or instructions associated with this parameter are displayed on the display device. The coupling can take place by means of direct communication between the display device and the input device or by means of indirect communication between the display device and the input device, for example via the control device.

0059In a preferred embodiment, the input device has an inner contour which is adapted to the outer contour of the display device, the input device surrounding the display device at least partially along a section of the outer contour of the display device. In this way, a connection can be created between the input device and the display device, in which the display device is at least partially surrounded by the input device. The display device can be provided within the input device, the term “within” also encompassing the case that the input device does not completely surround the display device. An essentially central arrangement of the input device around the display device is possible. In particular, the input device can contact the display device on one, two, three or four sides. A form fit and / or a frictional fit can be formed between the display device and the input device. In particular, the form fit - like the frictional connection - can optionally be released in order to separate the mechanical connection.

0060In a preferred embodiment, the display device is a tablet, iPad, notepad or the like, as a result of which a particularly simple configuration is possible. In the case of the display device, a display element essentially known from the prior art can be used. The aforementioned options for displaying are known and their use is familiar to an operator. The aforementioned options for designing the display device can enable intuitive operation of the display device.

0061In a preferred embodiment, the display device has a control unit which is designed for a context-sensitive display of information on the display device. For example, a value of a parameter for the operation of the earth boring device, information in connection with the parameter and / or instructions for the setting can be displayed by means of the control unit if it is important for the operator and / or the operator enters or changes such a parameter would like. If the operator inputs a parameter with the input device, for example, the parameter influenced or changed by the operator can be displayed by means of the control unit, even during the change or input. It is possible, for example, for a parameter whose value is displayed on the display device to be continuously reduced or increased by means of the input device. It is also possible for the control device to communicate with the control unit in order to display information, a value for a parameter, instructions and / or error messages.

0062For example, the control device of the earth drilling device can inform the control unit of the display device when a rod section has to be connected to the drilled drill pipe in order to continue drilling the earth. Furthermore, states of the earth boring device can be displayed which require an action by the operator.

0063In a preferred embodiment, the display device and the input device are functionally connected in such a way that when an input is made on the input device, the input is displayed by means of the display device. The input device can transmit a signal to the display device directly or indirectly via the control device of the earth boring device, by means of which it is displayed which parameter has been changed or changed with the earth boring device. should be entered so that the display device displays the current value of the parameter and / or parameters related to the parameter.

0064In a preferred embodiment, the display device has an input area which is adjacent to the input device when the input device and the display device are connected to one another. In this way, the possibility can be created that, in addition to the input option provided by the input device, the operator can make further input on the display device. The input on the display device can in particular be an input with which the information to be displayed, which is displayed on the display device, can be changed. In particular, the type of display can be changed. It is possible to call up information relating to the earth boring device. In addition, the input area provided on the display device enables a clear separation of the inputs that the operator can make. The inputs for changing, for example, the information to be displayed do not have to be provided on the input device; the input device can be limited to the input of the parameters necessary for the operation of the earth drilling device. The input option by means of the input on the display device can take place by means of a touch-sensitive display known from the prior art. At least one mechanically actuatable actuation element is preferably configured adjacent to the display device.

0065The display device can enable parameters, functions and / or changes to the representation on or on the display device, which - provided the display device has a touch-sensitive display - can be made as so-called inputs by touching, tapping, swiping the display or the like. However, it is also alternatively or additionally possible that inputs on the display device can be made possible by means of an integrated device or an additional device that can be coupled (for example by means of a cable connection and / or wirelessly, for example by means of Bluetooth). The integrated or additional device can be a mechanically operable actuating element (for example a push button, a rocker button), a keyboard, a mouse, a trackball, a graphics tablet, a microphone, a camera or a similar input device, in particular in the form of a peripheral device otherwise known in the computer sector, with which key inputs or typing inputs, audio inputs (voice input) and / or video inputs (gestures, Movement or the like) are possible.

0066In a preferred embodiment, the display device is (a) wirelessly or (b) wired connected to the control device of the earth drilling device. This enables a certain mobility of the display device. In the case of a wireless connection, the mobility of the display device is increased in relation to the freedom of movement of an operator.

0067In a preferred embodiment, the display device is designed for wireless data exchange by means of WLAN. In this way, a data protocol or transfer protocol can be used which is known and easy to handle. In particular, the data exchange or the functional coupling between the display device and the control device of the earth drilling device can be carried out separately from data exchange or the functional coupling between the input device and the control device of the earth drilling device are present. For example, a lower security in communication can be selected for the exchange of data between the display device and the control device of the earth drilling device.

0068In a preferred embodiment, one or more antennas are attached to the auger device for communication with the display device. The use of, in particular, two antennas on the earth drilling device offers the possibility that in each case the signal from the control device of the earth drilling device which is the best, most stable or strongest signal at the respective antenna can be used. When using multiple antennas, interference can be minimized or even eliminated. In a preferred embodiment, an antenna, in particular an integrated antenna, can be located on the display device. In a preferred embodiment, a further or additional antenna can be screwed onto the display device to increase the range. The possibility of increasing the range is particularly useful when the operator is very far away from the earth boring device over the course of the drilling route. It can also be provided that several antennas are provided on the display device, from each of which the signal is tapped, which is the best, most stable or strongest.

0069In a preferred embodiment, the input device and the display device have separate power supplies. This enables increased flexibility. The energy supply of the individual devices can be dimensioned smaller than an energy supply for the common energy supply of the input device and the display device. In addition, the energy supply of a conventional display device can be used.

0070In a preferred embodiment, the display device has communication means for transmitting data and / or signals between the display device and a location system for the drill head. As a result, in addition to the parameters or information that is displayed on the display device for the operation of the earth boring device, it is also possible to display on the display device where in three-dimensional space the drill head of the drill rod was determined by the locating system. The control unit can thus be designed to process the signals of a positioning system and to evaluate them in such a way as to display the current or determined location of the drill head. This display can be done in different ways. A graphic representation in a, in particular selectable, map, which can be three-dimensional or two-dimensional, is possible. It can be provided that the positioning system does not transmit the data directly to the display device, but rather transmits the data to a gateway which, in particular, collects all data - not just the location data - but also the operating data and the drilling data that are recorded. The gateway can then in turn send the location data and other data that is collected to a cloud. From here they can be called up, evaluated and transmitted. The display device is designed to evaluate the data. If it is described that the display device has communication means for transmitting data and / or signals between the display device and a location system, this also means that the display device can retrieve and / or evaluate this data, for example by retrieving it from the cloud. Alternatively or additionally, it is possible that the location data can also be sent directly from the gateway - without the interposition of a cloud - or also directly from the location system to the display device and used.

0071In a preferred embodiment, the display device has a data output which is provided in particular for outputting a log of the operation of the earth drilling device, in particular a log of the location of the drilling head detected by the positioning system at predetermined time intervals or continuously. In this way, an automatically generated log can be output at the data output, which can be archived for billing purposes, documentation of the drilling or the like. The data output can also be used for other possibilities.

0072In a preferred embodiment, a detection device is provided which is designed to detect the end of the drill string (a) in the area of ​​the earth boring device and / or (b) in the area of ​​a target pit of an earth borehole to be created, the detection device having transmission means which are designed To transmit signals to the display device and / or to the control device, the display device and / or the control device being designed, in order to process the signals of the detection device in such a way that the signals are presented to a user on the display device. In this way, an area can be recorded in which a (further) operator is usually provided who monitors the operation of the earth boring device. The information is displayed to the operator who controls the operation of the earth boring device by means of the input device by recording and displaying the recording on the display device. In this way, the operator who controls the operation of the earth boring device by means of the input device can display the corresponding end-side region of the drill rod with regard to the corresponding detection, regardless of the position of the operator. It can be provided that it is not necessary for the operator to be present himself in the corresponding end region of the drill rod. The signal from the detection device can be used. A further added benefit can be achieved with this, since if necessary another operator to carry out the earth drilling can be dispensed with and this person can be entrusted with other tasks.

0073In the context of the description, a “detection device” includes any device which is designed to detect the presence of a drill rod, in particular an end of a drill rod or a rod section or a drill head, in an area. The detection device can be designed as a device which determines a change in the presence of the end of a drill rod or rod section or of the drill head.

0074In a preferred embodiment, the detection device is a camera, an area scanner and / or a motion scanner, as a result of which known devices, the handling and use of which is common - albeit for other areas - can be used.

0075For the purposes of the description, a camera is any device that records an image of an area that can in particular be displayed on the display device. For this purpose, the display device can display the signals or information from the camera on at least part of the display device. The signals can be displayed immediately or processed by the control unit of the display device and / or the control device of the earth drilling device before the display.

0076For the purposes of the description, an area scanner is a device that can determine or detect a change in a presence in an area. The area scanner can be designed as a light barrier, light curtain or the like. The area scanner can be designed using ultrasound, electromagnetic radiation in the infrared range or radar waves.

0077For the purposes of the description, a motion scanner is a device that can determine or detect a movement in an area.

0078Both the area scanner and the motion scanner can be used in such a way that a message is sent to the display device if a motion has been detected in any form. It can also be provided that a signal from an area scanner or movement scanner is transmitted to the input device and a response from the area scanner and / or the movement scanner is displayed on a status display of the input device. It can also be provided that as soon as the area scanner and / or the motion scanner respond, an image from a camera is displayed on the display device, so that an image from an optionally present camera is only displayed when the area scanner and / or the motion scanner changes or have determined the presence of the end of a drill rod or rod section or of the drill head.

0079The invention also provides a method of controlling operation of an earth boring apparatus according to claim 33.

0080The invention also provides a use of an auger device having a control device for operating the auger device according to claim 34.

0081The invention is described in terms of three aspects relating to a system, a method and a use. The statements on the individual aspects complement one another, so that the statements for the system are also to be understood as statements of the description for the method and the use. The description of the system also includes actions in the sense of the procedure or procedural steps relating to the procedure and uses or Disclosed usage characteristics that apply to the respective aspects.

0082For the purposes of the description, the naming of a numerical value, in particular a length specification or an angle specification, includes not only the actual numerical value, but also - in order to take into account manufacturing tolerances in particular - a range around the specific numerical value, which is +/- 15%, preferably +/- - 10%, of the given numerical value.

0083The above statements, like the following description of exemplary embodiments, do not represent a waiver of specific embodiments or features.

0084The invention is explained in more detail below using an exemplary embodiment shown in the figures.

0086<figref idref="f0001">Fig. 1</figref> shows a schematic representation of an earth drilling device 1, with which an earth drilling can be carried out in the ground. Rod sections are stored in a rod magazine 2 with which the drill rod 3, which has already been drilled in the ground, can be extended.

0087The earth boring device 1 has a control device 4 for operating the earth boring device 1, which is shown schematically by means of the dashed box. The operation of the earth drilling device 1 can be controlled by means of the control device 4.

0088There is also an input device 5 that is functionally coupled to the control device 4 and is designed to input at least one parameter for the operation of the earth boring device 1. In particular, such a parameter can cause drilling to be started with the auger device 1 or a drilling carried out with the auger device 1 to be stopped. The input device 5 is designed as a remote control which communicates wirelessly with the control device 4 by means of electromagnetic waves.

0089The wireless communication between the input device 5 and the control device 4 is bidirectional communication in which the input device 5 both receives signals from the control device 4 and sends them to the control device 4. The bidirectional wireless communication is visualized by means of the double arrow ES.

0090Furthermore, a display device 6 is provided with which information and / or parameters for the operation of the earth drilling device 1 can be displayed. To display the information and parameters, the display device 6 is functionally coupled to the control device 4. The communication between the display device 6 and the control device 4 takes place wirelessly by means of electromagnetic waves. The communication is bidirectional, so that the display device 6 can both receive signals from the control device 4 and send them to the control device 4. The bidirectional communication is visualized with a double arrow AS.

0091Like the <figref idref="f0001">Fig. 2</figref> As can be seen, the display device 6 can be arranged in a receptacle 7 of the input device 5 in such a way that the display device 6 can be handled together with the input device 5 as a unit by an operator.

0092The input device 5 has several mechanically operable actuating elements 8, two of which are designed as control sticks. Furthermore, the input device 5 has an emergency stop switch 9 as a mechanically actuatable actuating element 8, which is designed as a push button. The actuating elements 8 designed as control sticks and the emergency stop switch 9 face an operator when the input device 5 is held and are located in a plane of the input device 5. Opposite to the surface on which the control sticks and the emergency Off switches 9 are arranged, two rotary actuators are designed as mechanically operable actuating elements 8 on the left and right of the input device 5.

0093A plurality of status displays 10 are provided on the left side of the input device 5, which provide information about a state with regard to the input device 5, the earth drilling device 1 and / or a communication between the input device 5 and the control device 4.

0094Furthermore, the input device 5 has a receiving space 11, which is provided on the underside of the input device 5 and is designed as a receiving compartment, for the arrangement of an energy supply to the input device 5.

0095A pivotable antenna 12 is provided for wireless communication with the control device 4, which antenna is pivoted with regard to its alignment and can be telescopically varied in length.

0096To protect the actuation of the mechanically actuatable actuating elements 8, a protective elevation 18 is configured on the input device 5, which is arranged in the area of ​​the emergency stop switch 9 and the control sticks.

0097For coupling a neck, shoulder or hip belt, connecting elements 13 are provided, with which the corresponding belt can be connected.

0098To accommodate the display device 6, the input device 5 has a base plate 14 which is essentially rectangular (cf. <figref idref="f0001">Fig. 1</figref>). The mechanically actuatable actuating elements 8 are formed on handle-like projections 15 of the base plate 14, each of which can be grasped by one hand of an operator in order to be able to carry out the actuation. The projections 15 extend in an upward direction and form an edge around the base plate 14. The projections 15 each form an edge on one side. The two edges that are formed by the projections 15 are opposite one another. On the other two sides of the rectangular base plate 14 there are further edge sections which extend upwards in the same direction as the edges which are formed by the projections 15. This creates an edge which at least partially surrounds the base plate 14 and in which the display device 6 can be arranged. A non-positive connection can be formed, the display device 6 at least partially engaging behind the projections 15 at the edges that are formed by the projections 15.

0099<figref idref="f0003 f0004">Figures 5 to 7</figref> show a further embodiment of the input device 5 with the display device 6 of FIG <figref idref="f0001 f0002">Figs. 2 to 4</figref>. In this case, the projections 15 of the input device 5 are not designed as handles that can be grasped with one hand. The representations on the left and right of the<figref idref="f0003 f0004">Figures 5 to 7</figref> show the area of ​​the projections 15 from the side. There is a control stick at the top, a rotary actuator pointing forwards, and two push buttons as mechanically operable actuating elements 8 per projection 15.

0100<figref idref="f0004">Fig. 8</figref> shows a system with a detection device 16 designed as a camera, which is intended to detect the drill rod 3 at the end in the area of ​​a target pit 17 of an earth borehole to be created. The detection device 16 has transmission means which are designed to transmit signals to the display device 6 and to the control device 4. The signals can be displayed on the display device 6; in particular, an image recorded by the camera can be displayed on the display device 6.
