Self-propelled pneumatic pipeline cleaning machine and cleaning method

Abstract

The invention discloses a self-propelled pneumatic pipeline cleaning machine and cleaning method. The cleaning machine comprises a pipeline cleaning mechanism and a monitoring device; the pipeline cleaning mechanism comprises a guiding plate, a braking mechanism, a cleaning head mechanism and a reciprocating driving mechanism; and the monitoring device comprises a controller, a first magnetic switch, a second magnetic switch, a first electromagnetic valve and a second electromagnetic valve. The cleaning method includes the steps that firstly, the self-propelled pneumatic pipeline cleaning machine is placed; secondly, the braking mechanism performs braking and the cleaning head mechanism performs radial expanding; thirdly, the inner wall of a pipeline is cleaned; and fourthly, when cleaningof the whole to-be-cleaned pipeline is completed, and the self-propelled pneumatic pipeline cleaning machine is taken out. The self-propelled pneumatic pipeline cleaning machine is simple in structure, capable of easily, conveniently and fast cleaning the inner wall of the pipeline and good in cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, and in particular relates to a self-propelled pneumatic pipeline cleaning machine and a cleaning method. Background technique [0002] Circular metal pipes are widely used in engineering and construction. Although circular metal pipes have been cleaned and oil-sealed at the factory. However, before processing or laying on site, the debris accumulated in the circular metal pipe during transportation and storage must be cleaned or the oil seal must be removed. Therefore it is very difficult to clean the inner wall of the circular metal pipe before laying. At present, most of the pipes are cleaned manually, which is not only laborious, labor-intensive, time-consuming, but also has low cleaning efficiency. With the development of technology, pipeline cleaning equipment that uses mechanized means to replace manual cleaning has emerged, but the current pipeline cleaning equipment still has ...

AI Technical Summary

Problems solved by technology

[0003] (1) Use the power supply to drive the pipe cleaning head to rotate through the motor, and realize the cleaning of the inner wall of the pipe through the rotational movement of the pipe cleaning head, but the cleaning effect is not good and the position of each cleaning is limited, and the pipe needs to be moved repeatedly to feed, inconvenient operation;

[0004] (2) The pipe cleaning equipment is relatively large in size and heavy, making it inconvenient to move and operate;

[0005] (3) Pipeline cleaning equipment generally only has the cleaning head extended into the pipeline for cleaning, and the drive that drives the cleaning head cannot enter the inner wall of the pipeline because of its large volume, so it is inconvenient to clean a long pipeline;

[0006] (4) The brush used in the current pipeline cleaning equipment only imitates manual scrubbing along the axis of the inner wall of the pipeline, and the brush cannot form a positive pressure on the inner wall of the pipeline to be cleaned, making the cleaning effect poor
