AI Technical Summary
Technical Problem
Traditional manual polishing of pipe inner walls suffers from high labor intensity for workers, slow construction progress, and inability to effectively handle small-diameter and complex pipe structures.
Method used
A pipe inner wall bendable polishing device was designed, including a chassis, a moving component and a polishing motor. The polishing motor drives the polishing component to rotate inside the pipe, and the moving component drives the polishing component to move on the chassis to achieve polishing of the pipe inner wall.
Benefits of technology
It enables effective polishing of pipe length, bends and welds, improves construction efficiency and overcomes the shortcomings of traditional polishing equipment.

Abstract
The present application relates to a pipe inner wall turnable polishing device. The polishing device comprises a base plate, a moving assembly and a polishing motor arranged on the base plate, a flexible shaft arranged at the output shaft end of the polishing motor, and a polishing assembly arranged at the end of the flexible shaft away from the polishing motor. After the polishing assembly is put into the pipe, the polishing motor is started, the polishing motor drives the polishing assembly to rotate in the pipe, the moving assembly drives the polishing assembly to move on the base plate so that the polishing assembly moves in the pipe, and the polishing assembly polishes the inner wall of the pipe. The pipe inner wall turnable polishing device can polish the inner wall of the pipe after the pipe is prefabricated, i.e. after the pipe fitting and the pipe are welded. The polishing device not only solves the problem that the polishing of the pipe is limited by the length of the pipe, the presence of the elbow pipe and the weld, realizes the polishing of the inner wall of the elbow pipe, but also improves the work efficiency and overcomes the shortcomings of the traditional polishing equipment.
