Steel pipe inner wall cleaning device

Abstract

The invention relates to a steel pipe inner wall cleaning device. The problem that the inner wall of a long and thin pipeline is inconvenient to clean is effectively solved. According to the technicalscheme, the device comprises a vertical support and a steel pipe body, wherein a rotating shaft in the front-back direction is installed on the support, a clamping device is fixed to the rotating shaft, the middle of the steel pipe body is clamped by the clamping device, and a plurality of rollers making contact with the outer edge face of the steel pipe body are arranged on the inner side face of the clamping device; the front side and the rear side of the steel pipe body are each provided with a vertical friction strip making contact with the outer edge face of the steel pipe body; a rust removal block capable of sliding left and right is arranged in the steel pipe body, the left end and the right end of the steel pipe body are each sleeved with a box body, a sleeve is inserted into each box body, a push rod capable of sliding left and right is installed in each sleeve, and a permanent magnet is fixed to the outer end of each push rod; and an electromagnet is fixed to the end portion of each sleeve. The electromagnets are electrified to push the push rods to move, so that the push rods push the rust removal block to move. The device is high in applicability, easy to operate, lowin manufacturing cost, good in rust removal effect and capable of achieving automatic rust removal.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a cleaning device for the inner wall of a steel pipe. Background technique [0002] Since the pipeline is generally slender, cleaning the inner wall of the pipeline has always been a problem that is not easy to solve. At the same time, in construction and other places, the inner wall of the pipeline is very easy to rust. If the rust is not removed in time, it is easy to cause the pipeline to be damaged. Severe local corrosion, which affects the safety of the pipeline; generally, the more common cleaning method is to use a longer shaft, and a brush is installed at the end of the shaft for cleaning. Using a long shaft will cause unstable rotation, and there is a large Operational risk; the more professional cleaning method is generally to use professional pipeline sandblasting tools, which have a good cleaning effect, but need to cooperate with relatively complete ...
