Description

Technical Field

[0001] The utility model relates to the technical field of oil well tools, in particular to an eccentric wellhead rotating wrench for an oil well. Background Art

[0002] When the eccentric wellhead of each oil field needs to be rotated for accident handling, it is usually done manually with tubing tongs; because the torque that can be transmitted by the tubing is small and the wellhead is easily damaged, it is not only difficult to operate, but also causes personal and equipment accidents. The existing Chinese patent with application number "CN201120475964.3" and patent name "Oil Well Eccentric Wellhead Rotating Wrench" discloses: "An oil well eccentric wellhead rotating wrench is composed of a wrench body and a handle, and its feature is that the wrench body with a wrench mouth and a wrench handle is connected to the tubular handle through a thread." It is operated by one person. When encountering a wellhead with a larger specification, the torque that can be transmitted is insufficient, and the eccentric wellhead cannot be rotated for operation. Summary of the invention

[0003] Based on the above problems, the purpose of the utility model is to provide an oil well eccentric wellhead rotating wrench which can transmit large torque and can be operated by multiple people to rotate the wellhead.

[0005] In the above structure, by setting three handles, the utility model can be operated by one to three workers to rotate the wellhead, and then when operating the square mouth (or tee) at the large-sized eccentric inlet, the more people operate at the same time, the more labor can be saved, and the efficiency of the operation is improved. By setting the connection hole, it is convenient for the user to put the external pipe on the handle and then connect and fix it with the ingot bolt, so that a large torque can be transmitted, reducing the difficulty of operation; after use, the external pipe and the handle are separated, so that the utility model can be stored conveniently, and when the eccentric wellhead needs to be adjusted multiple times, the wrench body is left on the eccentric wellhead for the next operation, and the external pipe is removed to facilitate others to pass through without taking up space.

[0006] The utility model is further configured such that the outer wall of the wrench body is downwardly extended with supporting feet, and the supporting feet are arranged in two groups opposite to each other, and an entrance end of the wrench is formed between the two groups of supporting feet, and among the three handles, two of them are respectively located on the outside of the supporting feet, and the third is located at a position opposite to the entrance end.

[0007] In the above structure, the supporting area of ​​the wrench body can be increased by providing the supporting feet, and the structural strength of the engagement between the wrench opening and the square opening (or tee) of the flange on the eccentric wellhead can be improved, thereby improving the reliability of the utility model.

[0008] The utility model is further configured that a support block protruding outwards is provided at the junction of the wrench body and the handle.

[0009] By adopting the above structure, the structural strength between the handle and the wrench body can be improved, and the supporting area of ​​the wrench body can be increased, thereby improving the reliability of the utility model.

[0010] The utility model is further configured that the cross section of the support block is arc-shaped.

[0011] The above structure can facilitate the user to grasp and avoid hurting the hand.

[0012] The utility model is further configured that a reinforcing end having an outer diameter greater than that of the handle is provided at the junction of the handle and the support block.

[0013] The above structure can further enhance the structural strength between the handle and the wrench body, thereby improving the reliability of the utility model.

[0014] The utility model is further configured that the handle, the support block, the reinforcement end and the wrench body are integrally configured.

[0015] The above structure can facilitate the processing and production of the utility model and improve the overall structural strength of the utility model.

[0016] The utility model is further configured that a reinforcing rib is provided between the handle at the supporting foot and the handle on the wrench body.

[0017] By adopting the above structure, the structural strength between the handles can be further improved, thereby improving the force-bearing strength of the utility model and improving the reliability of the utility model.

[0018] The utility model is further configured that the reinforcing rib is in an arc-shaped strip shape.

[0019] With the above structure, the reinforcing ribs can bear the force better and can reduce the occupied space. BRIEF DESCRIPTION OF THE DRAWINGS
