Anti-separation multipurpose wrench of sucker rod

Abstract

The invention relates to an anti-separation multipurpose wrench of a sucker rod. The anti-separation multipurpose wrench is composed of a plate (1), an anti-separation pin (2), a handle (3), a separating and separation handle (4), a reset spring (5), a first rivet (6) and a second rivet (7). The anti-separation multipurpose wrench is characterized in that the anti-separation pin (2) is connected with the separating handle (4) through the first rivet (6), the anti-separation pin (2) is arranged in a mounting hole of the plate through the second rivet (7), and the reset spring (5) is arranged in a spring hole of the plate. The anti-separation pin is always at the anti-separation position under the action of the reset spring. Under the action of the anti-separation pin, when the wrench is used alternately by two persons, the anti-separation multipurpose wrench of the sucker rod is separated from the hands and cannot be separated from the sucker rod, and use is safe and convenient. In the well repair process of the anti-separation multipurpose wrench of the sucker rod, burrs or iron scraps and like cannot fall in an oil well, the use time of the oil well is prolonged, and production cost is lowered.

Description

1. Technical field [0001] The invention relates to a special tool for disassembling and assembling a sucker rod in maintenance of an oil well produced in an oil field-a multi-purpose wrench for an anti-loosening sucker rod. It is suitable for the disassembly and assembly of sucker rods in oil well maintenance. 2. Background technology [0002] In oil field production, maintenance of oil wells is the basic work. Disassembly and assembly of sucker rods in oil well maintenance is the most important thing in maintenance. At present, there are two tools for disassembly and assembly of sucker rods: (1) using GB8406 -87 type pipe wrench (2) is a wrench. [0003] 1. Use a wrench, because the wrench torque is small, easy to damage, and it is old and heavy, so it is not used now. [0004] 2. When pipe wrench is used for disassembly and assembly of sucker rod in oil well maintenance, pipe wrench is used to clamp the squares at both ends of the sucker rod and rotate to complete the di...

AI Technical Summary

Problems solved by technology

[0004] 2. When pipe wrench is used for disassembly and assembly of sucker rod in oil well maintenance, pipe wrench is used to clamp the squares at both ends of the sucker rod and rotate to complete the disassembly and assembly of the sucker rod. During disassembly and assembly, because the teeth of the pipe pliers are easy to damage the four sides of the sucker rod at both ends, resulting in burrs and iron pins, an oil well is several kilometers long, and hundreds of sucker rods are required to repair an oil well at a time. If the rod is used thousands of times, a lot of burrs and iron pins will be produced, and because the teeth of the pipe wrench are high in hardness and brittle, they are also easy to lose teeth, all burrs, iron pins and broken teeth of the pipe wrench are easy to fall into the oil well, causing damage to the oil well

In short, the operation is troublesome, the use is unsafe, and the labor intensity is high
