Description

Technical Field

[0001] The utility model relates to the technical field of oilfield operation devices, in particular to a sucker rod buckle. Background Art

[0002] In oil production operations, the disassembly and replacement of sucker rods is a crucial step.

[0003] The traditional manual sucker rod inverting method mainly relies on the physical labor of wellhead operators, usually requiring 2 to 4 people to cooperate, using tubing pliers to rotate the sucker rod in a hand-to-hand manner to complete the unhooking operation. This method has many shortcomings and safety hazards; first, as the inverting process deepens, the torque borne by the sucker rod gradually increases, which places extremely high demands on the physical strength of the operators. However, the power of manual operation is limited, and it is difficult to maintain efficient inverting operations for a long time, thus affecting work efficiency; secondly, when manual operation copes with the gradually increasing torque, it is very easy for the sucker rod to generate reverse force rotation due to insufficient power or improper operation. This sudden reverse movement may not only damage tools and equipment, but more importantly, it seriously threatens the safety of operators and is very likely to cause personal injury; therefore, in order to solve the above problems, the present device proposes a sucker rod inverting device. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a sucker rod buckle.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sucker rod buckle includes two clamps, with clamp heads fixedly installed at both ends of the clamps, and clamp slots are provided on the clamp heads. The two clamps are fixed together by a connecting mechanism, and an installation groove is formed between two adjacent clamp slots. The sucker rod is installed inside the installation groove.

[0007] The above technical solution further includes: the card slot is semicircular in shape, and the inner wall of the card slot is provided with convex patterns.

[0008] Furthermore, the connecting mechanism includes a mounting screw and a locking nut. The fixture head is symmetrically provided with mounting holes. The mounting screw is movable through the interior of the mounting hole and is locked and fixed by the locking nut.

[0009] Furthermore, a driving component is provided on the outside of the clamping member, and the driving component is used to drive the clamping member to rotate.

[0010] Furthermore, the driving component is a sucker rod power tong.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, a clamp is provided, by which the sucker rod can be clamped and fixed, and then cooperated with the sucker rod power tongs to drive the sucker rod to rotate. There is no need to manually use the oil pipe tongs to manually rotate the sucker rod, which saves workers' physical strength, improves work efficiency, and improves protection for workers.

[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Refer to the attached Figure 1-2 The utility model proposes a sucker rod buckle, which includes two clamps 10, with clamp heads 11 fixedly installed at both ends of the clamps 10, and a clamping groove 12 is opened on the clamp head 11. The two clamps 10 are fixed together by a connecting mechanism, and an installation groove is formed between two adjacent clamping grooves 12, and the sucker rod is installed inside the installation groove.

[0020] The slot 12 is semicircular in shape, and the inner wall of the slot 12 is provided with convex patterns; wherein, the convex patterns in the slot 12 can improve the stability of the sucker rod in the installation slot.

[0021] The connection mechanism includes a mounting screw 21 and a locking nut 22 . A mounting hole 20 is symmetrically opened on the clamp head 11 . The mounting screw 21 movably passes through the interior of the mounting hole 20 and is locked and fixed by the locking nut 22 .

[0022] A driving component is provided on the outside of the clamp 10 , and the driving component is used to drive the clamp 10 to rotate.

[0023] The driving component is a sucker rod power tong.

[0024] In this embodiment, the working principle of the device is as follows: when using the device, the device can be installed on the sucker rod first. During installation, the two clamps 10 are first connected together, the sucker rod is placed in the installation groove, and then the installation screw 21 is inserted into the installation hole 20 and the installation screw 21 is locked and fixed by the locking nut 22. The installation of the device on the sucker rod is completed;

[0025] After the installation is completed, the sucker rod power tongs are clamped on the outer wall of the clamp 10, and the sucker rod power tongs are started to drive the clamp 10 to rotate, thereby driving the sucker rod to rotate and unload the force;

[0026] The device eliminates the need for manual use of tubing pliers to rotate the sucker rod, thereby saving workers' physical strength, improving work efficiency, and enhancing protection for workers.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
