Rust removal device for inner wall and outer wall of steel pipe

Abstract

The invention discloses a rust removal device for the inner wall and the outer wall of a steel pipe. The rust removal device for the inner wall and the outer wall of the steel pipe comprises a rail, adrive unit, an inner wall cleaning unit, an outer wall cleaning unit and the steel pipe, wherein one end of the steel pipe is fixedly connected with the drive unit; the drive unit is capable of driving the steel pipe to move along the rail to change the position and driving the steel pipe to rotate; the inner wall cleaning unit is fixed to the rail and stretches into the steel pipe from the freeend of the steel pipe; the outer wall cleaning unit is provided with a brush wheel; and the brush wheel can be away from the steel pipe or tightly pressed on the steel pipe. The rust removal device for the inner wall and the outer wall of the steel pipe has the advantages of realizing cleaning and rust removal for the inner wall and the outer wall simultaneously, lowering the labor intensity, saving the cleaning cost, and having a good popularization prospect.

Description

technical field [0001] The invention relates to the technical field of rust removal for steel pipes, in particular to a rust removal device for inner and outer walls of steel pipes. Background technique [0002] After long-term use, the inside and outside of the steel pipe will rust and affect the service life, and after the inside is rusted, it is easy to accumulate sundries and cause pipeline blockage. Therefore, it is necessary to dredge and derust the inside and outside of the pipeline in time. Shot blasting, this method has expensive equipment, inconvenient movement, and high cost of materials used, which limits the normal development of rust removal work to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a derusting unit capable of derusting the inner and outer walls of the steel pipe at the same time. [0004] The present invention solves the above technical problems through the followin...
