Overhead pipeline paint spraying walking device and overhead pipeline paint spraying method

Abstract

The invention discloses an overhead pipeline paint spraying walking device and an overhead pipeline paint spraying method. The overhead pipeline paint spraying walking device comprises an annular support, walking assemblies, limiting assemblies and spraying assemblies. The annular support is provided with an opening used for passing of a pipe bracket of an overhead pipeline. The walking assembliesare arranged on the inner side of the annular support and used for walking on the outer wall of the pipeline. The limiting assemblies are arranged on the inner side of the annular support and used for conducting limiting so that the annular support can move in the axial direction relative to the pipeline but cannot slide along the circumference of the pipeline. The spraying assemblies are connected with the annular support and used for conducting spraying on the pipeline. By means of the overhead pipeline paint spraying walking device and the overhead pipeline paint spraying method, aloft work of operators is effectively reduced, building of temporary facilities is reduced, safety is improved, manufacture and installation are convenient and rapid, and the spraying efficiency is high; thebottom faces of magnets are each in an arc shape matched with the outer wall of the pipeline, the attraction area is enlarged, and the pipeline attraction force is improved; and the annular support isformed by multiple connected arc-shaped plates together so that the overhead pipeline paint spraying walking device and the overhead pipeline paint spraying method can adapt to different diameters ofpipelines, and the application range is widened.

Description

technical field [0001] The invention relates to the technical field of pipeline spraying, in particular to an overhead pipeline paint spraying running device and a spraying method thereof. Background technique [0002] Traditional overhead pipeline paint spraying methods are mainly manual brushing and mechanical spraying. Among them, manual painting requires scaffolding, hanging baskets or springboards to be erected at high altitudes. Personnel work at high altitudes and use roller brushes for painting. The painting speed is very slow and the danger is great. [0003] Mechanical coating is generally divided into two types: pneumatic and electric. It also requires high-altitude workers to manually spray along the circumference of the pipeline. The spraying speed is slow and it is also dangerous. [0004] In view of this, there is an urgent need for an overhead pipeline spraying walking device to facilitate operation, increase the spraying speed, and ensure the safety of work...
