Pneumatic pin shaft disassembling tool for oil rig and control system of pneumatic pin shaft disassembling tool

Abstract

The invention provides a pneumatic pin shaft disassembling tool for an oil rig. An energy storage cylinder, a middle cover, a main piston cylinder body, a buffer pad, a guide cylinder, a quick exhaustpiston cylinder, a front cover and a sleeve are arranged in a series connection type structure and connected by a tightening screw into a whole to form a shell structure. A hammerhead, a piston rod,a main piston, an impacting pin and a quick exhaust piston are arranged in a series connection type structure and connected into a whole to form an impact component. The impact component is installedin an inner cavity of the shell structure. The back pressure of the piston is reduced during impact by energy storage at the back end of an air cylinder, high-speed jet release at the nozzle and fastexhaust at a front cylinder body, the impact speed of the piston is increased, the kinetic energy is promoted, a quick exhaust mechanism of the impacting pin is added at the central axis position of the piston rod, the striking intensity of the tool is guaranteed, the bounce-back force during operation is also reduced, and equipment continuous working capacity and operating personnel safety are ensured. Through the interlocking design of an air path control system of the pneumatic pin shaft disassembling tool, the single striking and continuous cyclic automatic striking functions are realized.

Description

Technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a pneumatic pin disassembly tool for an oil drilling rig and a control system thereof. Background technique [0002] Most of the existing oil drilling rig derrick and base structure components are assembled by connecting pins and lugs. When the drilling rig is relocated, it is necessary to manually disassemble and assemble with a hammer or hammer, which is labor intensive and low in efficiency. [0003] In recent years, in order to improve the efficiency of drilling operations and improve the operating environment, there has been a high demand for automated and intelligent drilling rigs. More and more drilling rigs adopt automatic control technology, and more and more drilling contractors hope that drilling rig disassembly and assembly operations can be reduced. Manual participation. [0004] At present, there is no automatic selling tool dedicated to disassembling and assemb...
