Abstract

The invention relates to a cleaning machine used for washing external wall of pipes, which pertains to the special equipment of industrial production and is suitable for cleaning the external wall of the petroleum chemical pipeline, removing scale, rust and the vitiated old anticorrosion coating, and spaying. The invention mainly consists of a frame, a driving wheel, protective strips, working parts, lateral wheels, sliders, a radial wheel wire rope, a wire rope driving wheel, a wire rope driven wheel, a driven wheel, a governor and counterweight. The working parts comprise a hydraulic water nozzle, an impactor, a wire brush, a polishing wheel and a paint gun. The invention is characterized in that the cleaning machine which is used for washing external wall of pipes can walk on the pipes and work continuously with high efficiency. A plurality of cleaning ways can be combined for use or a single cleaning way can be used. The invention has good washing effect.

Description

[0001] Field [0002] The invention relates to a pipeline outer wall cleaning machine, which belongs to special equipment for industrial production, and is suitable for cleaning the outer wall of petrochemical pipelines, descaling, derusting, removing invalid old anti-corrosion layers, and can also complete spraying operations. technical background [0003] Petrochemical oil and gas pipelines have a large diameter {700-1200mm} and are buried underground. After a few years, the original anti-corrosion layer will fail, and the pipeline will corrode, requiring re-corrosion. At present, manual descaling, rust removal and anti-corrosion coating are generally used There are also methods such as sand blasting and shot blasting, but the labor intensity of workers is high, the work efficiency is low, and the quality is poor. Contents of the invention [0004] The purpose of this invention is to design a cleaning machine for the outer wall of the pipeline, which can walk on the pipeli...
