Problems solved by technology

In the prior art, pipe joints can be divided into fixed type and pluggable type. The fixed type pipe joints mainly use welding to connect the pipes. Type pipe joints mainly use threaded connection or quick plug-in self-locking connection, and are disassembled by manually twisting the joint or pressing the locking device, which is completely dependent on manual operation, and the resistance is relatively large. This type of pipe joint cannot be used in space, high altitude, high temperature, and toxic environments

Abstract

The invention discloses a pipe joint automatic plugging device. Compared with the traditional manual operation, automation is realized, labor intensity is reduced; only one DC motor drive is required,which is simple to control, stable in operation and low in cost. The automatic plugging of the pipe joint is realized by the relative movement of the internal gear rack, which is compact, simple andreliable in structure. Relying on the top fixing member and the spring, the mechanism has a certain fault tolerance, which can overcome the position error between the moving part and the fixed part. the plugging joint adopts a marble-type self-locking joint, which is reliable in plugging and unplugging and reliable in sealing. It solves the problem that the manual plugging operation in many special occasions such as small space, high altitude, high temperature and toxic environment has great limitations and dangers.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection auxiliary equipment, and in particular relates to an automatic plugging and pulling device for pipe joints. Background technique [0002] Pipe joints are the most commonly used parts in the field of machinery industry. In the pipelines that need to be frequently disassembled in the field of hydraulic and pneumatic technology, pipe joints can realize quick disconnection and connection between pipelines. In the prior art, pipe joints can be divided into fixed type and pluggable type. The fixed type pipe joints mainly use welding to connect the pipes. Type pipe joints mainly use threaded connection or quick plug-in self-locking connection, and are disassembled by manually twisting the joint or pressing the locking device, which is completely dependent on manual operation, and the resistance is relatively large. This type of pipe joint cannot be used in space, high altitude, high temperat...
