Sucker rod buckle

Abstract

The invention relates to a mechanical auxiliary equipment for petroleum exploitation, in particular to a sucker rod upside-down device. An upside-down device for sucker rods, which has two clamping blocks. There is a semi-circular groove I vertically in the middle of the clamping block. The two semi-circular grooves I form a round hole. A clamping block is installed on the round hole. The lower part is several petals to tighten the teeth, and the middle part of the side of the clamp block is provided with a transverse transverse groove. One end of the bolt has a pin hole and is installed in the transverse groove through a pin post, and the other end is threaded with a nut. Two petal tubes are installed under the clamp block. The clamping body of the pipe wrench is vertically provided with a semicircular groove II in the middle of the clamping body of the pipe wrench. The upper part of the clamping body of the pipe wrench is fixedly connected with the clamping block through bolts, and the lower part of the clamping body of the pipe wrench is in the shape of a semicircle. The invention can greatly reduce the working intensity of the sucker rod undercut, and can save 60% of the labor; the work efficiency is greatly improved, and the dismantling time of each buckle is reduced from 30 minutes to 6-8 minutes, and the work efficiency is increased by 3.8 to 5 times; accidents occur The rate decreased significantly, from 15% to less than 1%.

Description

technical field [0001] The invention relates to a mechanical auxiliary equipment for petroleum exploitation, in particular to a sucker rod upside-down device. Background technique [0002] In oil well operations, lifting and lowering tubing and sucker rods is the most basic operation link. Because the diameter of the sucker rod is too thin, there is no suitable automatic tool to disassemble it, so it can only be disassembled manually with a pipe wrench. The disassembly operation is very difficult, mainly in the following aspects: First, the labor intensity is very large. The sucker rod is the only part that moves for a long time in the oil well string, so the threaded connection is very tight. In addition, the sucker rod body is very soft and tough, and the operator needs to use a lot of force when breaking the buckle with the pipe wrench. It is very time-consuming; the second is that the risk factor of this operation is very high. Because the sucker rod will also give a ...

Because the diameter of the sucker rod is too thin, there is no suitable automatic tool to disassemble it, so it can only be disassembled manually with a pipe wrench

The disassembly operation is very difficult, mainly in the following aspects: First, the labor intensity is very high

The sucker rod is the only part that moves for a long time in the oil well string, so the threaded connection is very tight. In addition, the sucker rod body is very soft and tough, and the operator needs to use a lot of force when breaking the buckle with the pipe wrench. It is time-consuming; second, the risk factor of this operation is very high

Because the sucker rod will also exert a large reaction force on the operator, the pipe wrench often bounces back to injure people or cause death
