In oil, gas and geothermal energy exploration, drilling operations are used to make boreholes, or wells, in the ground. Modern drilling rigs can include two, three, or even four mast parts for connection

<p dir="rtl">5 Cascading and hoisting over the infrastructure. Drilling rigs are transported to the locations where drilling activity begins. Once transported, large tower components are moved from the transport trailer to interlock with other components on the drilling pad.</p>

Moving a full size drilling rig requires significant disassembly and reassembly of the substructure, mast, and related component. Speed ​​of disassembly and reassembly affects profits but comes safety

<p dir="rtl">10 in the first place. Minimal disassembly reduces errors and delays in reassembly.</p>

Transportation and cost constraints eliminate many design opportunities for building drilling rigs that can drill a well faster. Conventional drilling involves having a drill bit at the bottom of the well. The bottom-hole assembly is located directly above the drill bit where directional sensors and communications equipment are located.

<p dir="rtl">15 equipment, batteries, mud motors, and stabilizing equipment to assist in guiding the drill bit to the desired subsurface target area.</p>

The drill collars are located above the bottom-hole assembly to provide a non-collapse source of weight to assist the drill bit in crushing formations

<p dir="rtl">20 formation. A heavyweight drill pipe sits atop the drill collars to achieve</p>

safety. The remainder of a drill string is mostly a drill pipe, designed to undergo tension. Each drill pipe is approximately 30 feet long, but lengths vary depending on the type. It is common for drill pipe lengths to be stored in "double sets" (two continuous lengths), "triple sets" (three continuous lengths), or even "quadruples" (four lengths of

<p dir="rtl">5 connected(.</p>

10

When the drill bit wears out, or when service, maintenance or modifications to the bottom-hole assembly need to be performed, the drill string (drill pipe and other components) is removed from the wellbore and returned. When the entire drill string is removed from the well, it is usually detached and returned in double or triple sets until the drill bit has been repaired and replaced. This process of pulling everything out of the hole and running everything back into the hole is known as "releasing".

The release or separation is performed at a time other than the time of excavation and, therefore, is costly. Efforts have long been made to devise ways to avoid, or at least speed up, this separation. Three-circuit assemblies are faster than double-circuit assemblies because they reduce the number of threaded connections required to be disassembled and reconnected

<p dir="rtl">15 after that. Threes are longer and therefore more difficult to handle due to their length, weight, and the natural waveforms that occur when they are moved. Manual handling can be done by moving the pipe in the drilling rig and at the level of the drilling ground linearly.</p>

20

A drilling rig with the ability to increase safety and reduce separation time is desirable. It is desirable to have a drilling rig with the ability to deliver drill pipe uprights to riggers instead of elevators and traditional overhead gear. It is also desirable to have a system that includes redundancy (additional elements / redundancies), so that if one element of the system fails or service is required, the task performed by this unit can be performed by another unit on the drilling rig.

Most attempts to automate the suspension of tubes have been found at sea. However, pipe connection solutions on offshore drilling rigs are rarely convertible to rigs

12427

Onshore land rigs, due to many differences in economic feasibility, size, weight, and transportation considerations.

Thus, there is still a need for a reliable automatic suspension unit that offers redundancy (additional elements), a safe, reliable, cost-effective, and practical consideration to weight and size constraints to deliver

Thus, after describing the different models, it is noted that the discovered models are illustrative and not restrictive in nature5 and a wide range of variations, modifications, changes, and substitutions can be expected in the disclosure

The former, and in some cases, some attributes may be used without the corresponding use of the other attributes. Many of these variations and modifications may be deemed desirable by a person skilled in the art, based on a review of the previous embodiment descriptions. Accordingly, it is appropriate to interpret the enclosed claims broadly and in a manner consistent with the scope of the disclosure.
