AI Technical Summary

Technical Problem

The existing PE steel wire mesh reinforced pipe repair process suffers from poor operational stability, especially in field or large-diameter pipeline repair, resulting in fluctuating repair quality, low efficiency, and dependence on operator skills.

Method used

A repair device comprising a gear ring, a clamping plate, a sealing gun, and a motor was designed. By precisely positioning the clamping plate against the inner wall of the pipe, fixing it with an anti-slip rubber pad, and mechanically limiting it with a return spring, the meshing of the motor output shaft with the gear ring is ensured, thereby achieving stability and continuity in the repair process.

Benefits of technology

This achieves stability and continuity in the repair process, ensures uniform sealing of the welded surfaces, improves repair quality and efficiency, and reduces reliance on operator skills.

Abstract

This utility model relates to the field of pipeline repair equipment, and more particularly to a repair device for processing PE steel wire mesh reinforced pipes, including a toothed ring and a sealing gun. A clamping plate that contacts the pipe is connected inside the toothed ring. An installation block is connected to the inner ring of the toothed ring. Fixing screws are threaded onto the left and right sides of the installation block. A fixing block is connected to the end of the sealing gun. The fixing block is slidably connected to the installation block, and the installation block and fixing block are connected by fixing screws. A connecting plate is slidably connected to the side of the toothed ring, and a motor is slidably connected to the top of the connecting plate. The connecting plate is equipped with a mounting component for stabilizing the motor, and the motor's output shaft is equipped with a gear that meshes with the toothed ring. Through the arc-shaped fine stripes of the outer protective pad of the clamping plate and the slight resistance on the inner side of the pipe, the clamping plate rotates smoothly and axial sliding is restricted when inserted, thereby achieving precise positioning of the toothed ring and the inner wall of the pipe. During the repair process, the sealing gun does not deviate, achieving the purpose of stabilizing the repair process.
