Spheroidal graphite cast pipe connector anti-falling device

Abstract

The invention relates to the technical field of spheroidal graphite cast pipes, and discloses a spheroidal graphite cast pipe connector anti-disengaging device which comprises a first connecting shell, and a polishing cleaning mechanism and an active cleaning mechanism are arranged at the top of the first connecting shell; the anti-falling cleaning mechanism comprises a groove, a first electric telescopic cylinder, a second connecting shell, a motor protection cover, a motor, a motor shaft, a threaded rod, a movable shell, a bearing, a second electric telescopic cylinder, a curved shell, a motor, a motor shaft, blowing fan blades and a rotating rod. The electric telescopic cylinder and the curved shell are arranged on the movable shell, the movable shell can be driven by the threaded rod to move left and right on the surface of the pipeline, and due to the fact that the motors and the polishing brushes are arranged in the curved shell, multi-angle polishing and cleaning can be conducted on the pipeline from multiple positions of the pipeline; and when the motor drives the polishing brush to rotate, the blowing fan blades can be driven to rotate, and the blowing fan blades pass through the round holes to blow air to clean the surface of the pipeline.

Description

technical field [0001] The invention relates to the technical field of ductile cast pipes, in particular to an anti-dropping device for joints of ductile cast pipes. Background technique [0002] In the process of reinforcement and installation of ductile cast pipes on the installation surface, it is often necessary to add an additional anti-detachment device at the interface of the pipe body to achieve a reinforcement effect and reduce the phenomenon of detachment at the interface of the pipe body. [0003] Patent No. CN202020183186.X discloses a nodular cast pipe interface anti-dropping device, including a base plate, the outer surface of the upper end of the base plate is fixedly equipped with guide plates, and the outer surfaces of both sides of the guide plate exceed the outer surfaces of both sides of the base plate In the plane where the upper end of the guide plate is slidingly fitted with a sliding seat, the upper end of the sliding seat is connected with a fixed cl...

AI Technical Summary

Problems solved by technology

[0004] However, the existing nodular cast pipe interface anti-loosening device can only simply clamp the pipe to prevent it from coming off during use, and cannot process the surface of the pipe during the process of clamping the pipe to increase the function of the device. The function of the device is relatively single, and the existing clamping mechanism does not have a good clamping effect
