Pipe maintenance device capable of removing corrosion rust of inner wall gullies

Abstract

The invention discloses a pipe maintenance device capable of removing corrosion rust of inner wall gullies, and belongs to the technical field of pipe maintenance. The pipe maintenance device capable of removing corrosion rust of the inner wall gullies comprises a base, a square groove is formed at the position, opposite to the left end of a supporting column, of the outer wall of a fixing plate located at the right side, a fixing shaft is fixedly arranged at the position, opposite to the center of a grinding column, of the middle of a cavity, and the outer wall of the fixing shaft is linearly sleeved with a plurality of rotating discs at equal intervals; and a plurality of tooth grooves are annularly formed in the circumferential outer walls of the rotating discs at equal intervals, a plurality of bevel gears are annularly arranged at the left sides of the rotating discs at equal intervals, the outer side ends of the bevel gears are coaxially and fixedly connected with shaft centers, extension rods are inserted into the outer side ends of the shaft centers, grinding balls are coaxially and fixedly connected to the outer side ends of the extension rods, and the extension rods are sleeved with compression springs. According to the device, the pipe inner wall gullies and grooves can be ground, the comprehensiveness of maintenance and rust removal work is guaranteed to the maximum extent, hidden dangers generated by rusted parts which are difficult to ground in the gullies and the grooves are eliminated, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of pipe maintenance, and more specifically relates to a pipe maintenance device capable of removing corrosion and rust on inner wall gullies. Background technique [0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the materials of pipes have gradually become more diversified. It greatly increases the difficulty of pipe maintenance, among which metal pipes are the most difficult to maintain. During the use of metal pipes, not only the outer wall will be corroded by wind and sun, but also the inner wall will be affected by various circulating materials. Under the environment, some rust will be slowly produced, especially the water pipes. When the water flows along the interior for a long time, grooves and ravines will be formed on th...

[0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, the materials of pipes have gradually become more diversified. It greatly increases the difficulty of pipe maintenance, among which metal pipes are the most difficult to maintain. During the use of metal pipes, not only the outer wall will be corroded by wind and sun, but also the inner wall will be affected by various circulating materials. Under the environment, some rust will be slowly produced, especially the water pipes. When the water flows along the interior for a long time, grooves and ravines will be formed on the inner wall of the pipes. Therefore, the staff need to maintain and derust the pipes from time to time. There are many existing methods It is to use sandpaper to polish the outer wall and use a derusting rod to polish the inner side of the pipe. This kind of grinding method can be used for the inner wall of the pipe. rust effect, which will be a major hidden danger in the subsequent use of pipes. Some of the existing solutions for the rust removal of the inner wall of the pipe use multiple elastically expandable rust removal heads uniformly arranged in the circumferential direction to remove the rust on the inner wall. For example CN112355851A, CN111941245A, but this type of solution can only be used for the rust removal of the inner wall of the pipeline with a fixed curvature. In view of this, we propose a pipe maintenance device that can remove the corrosion and rust of the inner wall gully
