Corrugated pipe butt joint device

Abstract

The invention discloses a corrugated pipe butt joint device, which comprises an upper permanent seat, a lower permanent seat, an upper supporting seat, a lower supporting seat and a butt joint buckling mechanism, wherein the butt joint buckling mechanism comprises an upper buckle and a lower buckle; the lower permanent seat, the lower supporting seat and the lower buckle are rotatably provided with the upper permanent seat, the upper supporting seat and the upper buckle through the same smooth bar; one end of an upper lead screw is rotatably connected with the upper permanent seat, and the other end rotatably penetrates through the upper buckle and the upper supporting seat to be fixedly connected with an upper driven belt pulley; one end of a lower lead screw is rotatably connected with the lower permanent seat, and the other end rotatably penetrates through the lower buckle and the lower supporting seat to be fixedly connected with a lower driven belt pulley; the upper driven belt pulley and the lower driven belt pulley are connected with the same driving belt pulley through one belt; the upper permanent seat, the upper supporting seat and the upper buckle are simultaneously opened and buckled independently relative to the lower permanent seat, the lower supporting seat and the lower buckle; the upper permanent seat and the lower permanent seat form a fixed groove; the uppersupporting seat and the lower supporting seat form a supporting groove; and the upper buckle and the lower buckle form a clamping groove. According to the corrugated pipe butt joint device, a corrugated pipe is evenly stressed to prevent from being damaged, and butt joint quality is high.

Description

technical field [0001] The invention relates to a device for butt jointing metal bellows, which belongs to the technical field of pipe string socket tools. Background technique [0002] Bellows is a tubular elastic element formed by connecting foldable corrugated sheets along the folding direction. It has the functions of compensating pipeline deformation and shock absorption, and is widely used in the construction field. When the corrugated pipe is actually used, it is usually necessary to connect multiple corrugated pipes to each other. At present, the common method of bellows docking in the construction field is to first slightly insert the socket of the first bellows into the socket of the second bellows, fix the second bellows, and then push the first bellows with hemp rope and a lever block. The smaller socket of the first bellows is pushed deeper into the larger socket of the second bellows, thereby connecting or docking the two. From actual implementation, it can b...

AI Technical Summary

Problems solved by technology

From the actual implementation, it can be found that the method of pushing the bellows with the hemp rope and the lever hoist can easily pull the bellows to the wrong side, resulting in the problem that the two bellows are not well connected to each other, which needs to be solved
