Description

Technical Field

[0001] This utility model belongs to the field of drill pipe technology, and in particular relates to a drill pipe self-unloading clamp. Background Technology

[0002] Drill pipe is a steel pipe with threads at the tail, used to connect the drilling rig's surface equipment to the drilling equipment or bottom hole assembly located at the bottom of the well. The purpose of drill pipe is to transport drilling mud to the drill bit and, together with the drill bit, raise, lower, or rotate the bottom hole assembly. Drill pipe must be able to withstand enormous internal and external pressure, torsion, bending, and vibration. In the process of oil and gas extraction and refining, drill pipe can be reused multiple times. Drill pipe is divided into three categories: angular drill pipe, drill rod, and heavy-duty drill pipe.

[0003] When operating, the drill pipe is usually lengthened according to the working depth. The two drill pipes are connected by threads. The problem with the above technology is that, in the existing technology, when disassembling the two drill pipes, it is necessary to manually disassemble them with the cooperation of two people. When the two drill pipes are tightly connected by threads, disassembly is difficult and affects the progress of the operation. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a drill pipe self-unloading clamp that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a drill pipe self-unloading clamp includes a base plate, a vertical rod, and a top plate. The bottom of the vertical rod is fixedly installed on the top of the base plate, and the bottom of the top plate is fixedly installed on the top of the vertical rod. A positioning mechanism is installed on the top of the base plate, an adjustment mechanism is installed on the top of the base plate, an installation groove is installed on the top of the top plate, a clamping mechanism is installed on the top of the top plate, and a fixing mechanism is installed on the top of the top plate.

[0006] To improve the fixation of the bottom drill rod, preferably, the positioning mechanism includes a positioning plate, a positioning block, and a positioning rod. The surface of the positioning plate is fixedly installed on the surface of the vertical rod, the surface of the positioning rod is movably installed in the middle of the positioning plate, and one side of the positioning block is fixedly installed on one end of the positioning rod. By moving the positioning rod, the positioning rod drives the positioning block to move, and the positioning block fixes the bottom rotating rod.

[0007] To facilitate the movement of the positioning rod, preferably, the adjusting mechanism includes a threaded sleeve, a threaded rod, and a connecting plate. The front side of one side of the connecting plate is fixedly installed on the other end of the positioning rod, and one end of the threaded rod is fixedly installed on the rear side of one side of the connecting plate. The middle part of the threaded sleeve is movably installed on the surface of the threaded rod. The middle part of the threaded sleeve and the surface of the threaded rod are connected by threads. By rotating the threaded sleeve, the threaded sleeve drives the connecting plate to move through the threaded rod, and the connecting plate drives the positioning rod to move.

[0008] To facilitate the fixing of the top drill rod, preferably, the clamping mechanism includes a clamping block, a mounting plate, and a mounting rod. The bottom of the mounting rod is movably mounted on the inner wall of the mounting groove, the inner wall of the mounting plate is movably mounted on the surface of the mounting rod, one side of the clamping block is fixedly mounted on one side of the mounting plate, and a sliding rod is installed in the middle of the mounting rod. The top drill rod can be fixed by moving the clamping block.

[0009] To facilitate the movement of the clamping block, preferably, the fixing mechanism includes a lead screw, a threaded block, and a rotating rod. The front side of the threaded block is fixedly installed on the rear side of the clamping block, the surface of the lead screw is movably installed in the middle of the threaded block, and one side of the lead screw is fixedly installed at one end of the rotating rod. The surface of the lead screw and the middle of the threaded block are connected by a thread. By rotating the rotating rod, the rotating rod drives the lead screw to rotate, and the lead screw drives the threaded block to move towards the center or both sides through the threaded connection. The clamping block is moved through the threaded block.

[0010] To improve the anti-slip properties of the drill rod, preferably, anti-slip plates are installed on the inner walls of both the clamping block and the positioning block. The anti-slip plates are made of rubber and can be installed on the clamping block and the positioning block to provide anti-slip protection for the drill rod.

[0011] To improve the limiting effect on the mounting rod, preferably, both ends of the slide rod are fixedly installed on the inner wall of the mounting groove, and the middle part of the mounting rod is movably installed on the surface of the slide rod. The mounting rod can be installed on the slide rod, and the slide rod can limit the position of the mounting rod.

[0012] This utility model, by setting up a base plate, vertical rod, top plate, positioning mechanism, adjustment mechanism, mounting groove, clamping mechanism, and fixing mechanism, first moves the overall fixture to the surfaces of the two drill rods. Rotating the threaded sleeve causes the threaded rod to move, which in turn moves the connecting plate, which in turn moves the positioning block, which in turn moves the anti-slip plate, thus fixing the bottom drill rod. Next, rotating the rotating rod causes the lead screw to rotate, which in turn moves the threaded block, which in turn moves the clamping block, which in turn moves the anti-slip plate, fixing the top drill rod. Finally, rotating the clamping block allows the top drill rod to be disassembled from the bottom drill rod. This solves the problem in existing technologies where disassembling two drill rods requires two people and is difficult when the two drill rods are tightly connected by threads, thus affecting the work progress.
