Portable pipe clamping tightening and releasing device

Abstract

The invention provides a portable pipe clamping tightening and releasing device. The portable pipe clamping tightening and releasing device comprises two circular hoops. The two hoops are arranged left and right, and the central axes of the two hoops are coaxial. Each hoop comprises a semicircular upper hoop body and a semicircular lower hoop body, and the outer sides of the two ends of the upperhoop body and the outer sides of the two ends of the lower hoop body are both fixedly provided with horizontal plates; the horizontal plates are all provided with mounting holes; a bolt penetrates through the mounting holes of the two corresponding horizontal plates, and a nut is mounted at the other end of the bolt in a matched mode; a plurality of rotary shaft distributed uniformly around the central axis of each hoop body are arranged on the inner ring of the hoop body and are perpendicular to the central axis of the corresponding rotary shaft. The portable pipe clamping tightening and releasing device. The portable pipe clamping tightening and releasing device can quickly and efficiently complete draw two buried water pipes to get close and separated without manual operation, manpoweris saved, and quick and efficient installation and maintenance are realized. The portable pipe clamping tightening and releasing device. The portable pipe clamping tightening and releasing device is simple and ingenious in structure, convenient to use and capable of automatically completing connection and separation of large-size pipelines.

Description

technical field [0001] The invention belongs to the field of pipeline construction equipment, in particular to a convenient pipe clamping and retracting device. Background technique [0002] Existing buried water pipes, including water supply pipes and drainage pipes, need to be installed after the two separated pipes are axially pulled together and then butt-connected; during pipeline maintenance, it may also be necessary to axially separate the two butt-connected pipes. The buried water pipe installation tool in the prior art generally adopts two hoops to be fixedly sleeved on the two separated buried water pipes, and then the two buried water pipes are axially dragged and pulled together by a wire rope tightener. Butt installation. The hoop used is usually composed of a semicircular left hoop and a semicircular right hoop connected by bolts. There is a pendant in the middle of the left hoop and the right hoop respectively. The wire rope sleeve of the wire rope tightener ...

AI Technical Summary

Problems solved by technology

This kind of wire rope tightener is only used to pull the two separated pipes together, and cannot separate the two butted pipes

Moreover, this traditional equipment requires manpower to operate, and the construction efficiency is low. It is difficult to complete the installation and separation of large-scale pipelines by manpower.
