Steel pipe inner wall surface cleaning device

Abstract

The steel pipe inner wall surface cleaning device comprises a steel pipe supporting and rotating support (1), a to-be-cleaned steel pipe (2) is arranged on the steel pipe supporting and rotating support (1), and a movable cleaning mechanism (3) is arranged on the side face of the steel pipe supporting and rotating support (1); the movable cleaning mechanism (3) comprises a ground rail (4), a movable trolley (5) is arranged on the ground rail (4), a lifting adjusting mechanism (6) is arranged above the movable trolley (5), and a cleaning assembly (7) is arranged on the lifting adjusting mechanism (6); the cleaning assembly (7) comprises a cleaning driving motor (701), a main polishing rod (702) of a square tube structure is arranged at the output end of the cleaning driving motor (701), and a polishing head (703) is arranged at the end of the main polishing rod (702). The cleaning device has the characteristic that the cleaning effect can be effectively improved.

Description

technical field [0001] The invention relates to a cleaning device for the inner wall of a steel pipe, in particular to a cleaning device for the inner wall of a steel pipe. Background technique [0002] Circular steel pipe is a steel product with a hollow section and a length greater than the diameter or circumference. With the rapid development of the iron and steel smelting industry, the scope of use of steel pipes has become more extensive. During the production and processing of steel pipes, the inner and outer walls of the steel pipes need to be cleaned, and only after cleaning can subsequent heat treatment and galvanizing processes be carried out. For the cleaning of the inner wall of the steel pipe, a special cleaning device is generally used for cleaning treatment. The cleaning device is composed of a circular tube-shaped main throwing rod and a polishing head. The main throwing rod advances so that the polishing head extends into the steel pipe, and the polishing h...

AI Technical Summary

Problems solved by technology

However, due to the long length and low strength of the existing polishing rod, the front end of the polishing rod will fall down during the cleaning process, so that the contact between the polishing head and the inner wall of the steel pipe is uneven, and the smoothness of the inner wall of the steel pipe is easily affected, resulting in Poor overall polish cleaning performance

Therefore, the prior art has the problem of poor cleaning effect
