A pneumatic union dismantling machine

Abstract

A pneumatic union dismantling machine, which relates to a mechanical dismantling device. The pneumatic main engine is composed of a drill rod, a locking ring, a cylinder assembly, a bow handle and a control handle. At the rear end of the bow handle There is a control handle on the upper side, cross bars are set on both sides of the bow handle, limit belts are set on the forehead cross bars on both sides of the bow handle, and a cylinder assembly is set on the front end of the bow handle , a locking ring is provided at the front end of the cylinder assembly, a drill rod snap-fitted with the locking ring is provided at the front end of the locking ring, and a drill rod that is snap-connected with the locking ring is provided at the front end of the pneumatic main engine. Plug and connect the union card seat; the invention is simple and easy to use. After connecting the air source, use the card seat to clamp the union that needs to be disassembled, and pull the control handle to realize assembly and disassembly. It is operable, improves work efficiency, reduces labor intensity of workers, and avoids damage to the body and workpiece caused by manual brute force disassembly.

Description

technical field [0001] The invention relates to a mechanical disassembly and assembly device, in particular to a pneumatic union disassembly and assembly machine. Background technique [0002] As is known, in the process of drilling and workover operations in the oil field, the pipelines are basically fixedly connected by unions. During the disassembly and assembly of unions, workers often rely on workers to hit and fasten them with sledgehammers. The method of artificially controlling the strength to knock and disassemble the union is artificially controlled during the operation process, and the striking strength is uneven, which is prone to damage to the pipeline, union, union fixing sleeve and sealing material. In addition, during the beating process It is easy to have safety hazards such as slipping, breaking off, falling off of the chisel rod, and sparks. If the union is rusted, it will make disassembly and assembly very difficult, time-consuming and laborious, and affe...

[0002] As is known, in the process of drilling and workover operations in the oil field, the pipelines are basically fixedly connected by unions. During the disassembly and assembly of unions, workers often rely on workers to hit and fasten them with sledgehammers. The method of artificially controlling the strength to knock and disassemble the union is artificially controlled during the operation process, and the striking strength is uneven, which is prone to damage to the pipeline, union, union fixing sleeve and sealing material. In addition, during the beating process It is prone to safety hazards such as slipping, breaking off, falling off of the chisel rod, and sparks. If the union is rusted, it will make disassembly and assembly very difficult, time-consuming and laborious, and affect the construction progress and quality.

[0003] Nowadays, in order to realize fast and efficient disassembly and assembly of the union, many methods of pneumatic or electric striking are disclosed in the prior art to disassemble and assemble the union. However, the disassembly and assembly of the union in this way first needs to be matched with the union The compatible card holder can only be disassembled and assembled after the card holder is used to buckle the union, which leads to the need to carry a large number of card holders for cooperative use during the process of disassembling and assembling the union, which is very inconvenient; in addition, During the disassembly process, due to the pneumatic or electric automation method, the reaction force suffered by the worker is relatively large. If the union is not held firmly, the disassembly operation of the union will be affected, and excessive force will also cause damage to the worker's arm.
