Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The pneumatic pin shaft dismounting tool for oil drilling rigs of the present invention comprises a shell structure and an impact component installed inside the shell structure.

[0034] Such as figure 1 As shown, the shell structure includes the shell structure including the energy storage cylinder 1, the middle cover 2, the main piston cylinder 3, the guide cylinder 5, the quick-displacement piston cylinder 6, the front cover 7, Sleeve 8, the fixed connection method of which can be fixed connection with tension screw 20; the energy storage cylinder 1 has an air inlet K4; the middle cover 2 is a rotary body, and the middle cover 2 has a tapered hole in the axial direction. The large end of the hole is close to the energy storage cylinder 1, and the tapered hole is conducive to the introduction of gas; the guide cylinder 5 has a guide...

Abstract

The pneumatic pin shaft dismounting tool used for petroleum drilling rigs of the present invention includes an energy storage cylinder, a middle cover, a main piston cylinder, a buffer pad, a guide cylinder, a quick-displacement piston cylinder, a front cover and a sleeve in a serial structure The shell structure is arranged and connected as a whole with a tension screw. The hammer head, piston rod, main piston, firing pin and snap piston are arranged in series and connected together to form an impact part; the impact part is installed in the inner cavity of the shell structure. The invention utilizes energy storage at the rear end of the cylinder, high-speed jet release at the nozzle, and quick exhaust of the front cylinder body to reduce the back pressure of the piston during impact, increase the impact speed of the piston and increase the kinetic energy, and increase the force of the striker on the central axis of the piston rod. The rapid exhaust mechanism ensures that the force of the tool is eliminated and reduces the recoil force during operation, ensuring the continuous working ability of the equipment and the safety of the operator; through the interlocking design of the air circuit control system of the pneumatic pin dismounting tool, it is realized It has the functions of single cancellation and continuous cycle automatic cancellation.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a pneumatic pin dismounting tool for oil drilling rigs and a control system thereof. Background technique [0002] Most of the existing oil drilling rig derricks and base structural parts are assembled in the form of pin shaft and lug plate connection. When the drilling rig is relocated, it needs to be disassembled manually with a hammer or a hammer, which is labor-intensive and low-efficiency. [0003] In recent years, in order to improve the efficiency of drilling operations and improve the working environment, automation and intelligent drilling rigs are highly appealed. More and more drilling rigs adopt automatic control technology, and more and more drilling contractors hope that the disassembly and assembly operations of drilling rigs can also be reduced. Human involvement. [0004] At present, there is no automatic knockout tool on the market that is dedicated...
