Pipeline inner wall silicone rubber section coating equipment and working method thereof

Abstract

The invention relates to the technical field of pipeline inner wall silicone rubber section coating, in particular to pipeline inner wall silicone rubber section coating equipment and a working method thereof.The pipeline inner wall silicone rubber section coating equipment comprises a first base table, a second base table, a material storage box, a pipe taking assembly, a pipe conveying assembly, a pipe drawing assembly and a coating assembly; meanwhile, the inner wall of the pipeline is subjected to section coating of silicon rubber through rotation of the section coating rotary drum, the same pressure can be applied to the inner wall of the pipeline at each position of the section coating rotary drum, and then the inner wall of the pipeline is subjected to section coating more evenly through the equipment; the sleeve brush can prevent the section coating rotary drum from scratching the inner wall of the pipeline, the inner wall of the pipeline is protected, the coating box and the coating pipe are arranged, silicone rubber coating can be continuously provided for the section coating rotary drum, and silicone rubber coated on the inner wall of the pipeline in a section mode can be thick enough.

Description

technical field [0001] The invention relates to the technical field of segmental coating of silicone rubber on the inner wall of a pipeline, in particular to equipment for segmental coating of silicone rubber on the inner wall of a pipeline and a working method thereof. Background technique [0002] Because of its good water resistance, silicone rubber is often coated on the inner wall of the pipeline to enhance the corrosion resistance of the pipeline in a humid environment. Because the space on the inner wall of the pipeline is relatively narrow, when coating silicone rubber on the inner wall of the pipeline, it is necessary to use a section Coating equipment, through the section coating equipment into the pipeline for section coating. [0003] The Chinese patent application number CN201610086617.9 discloses a mechanical arm for spraying the inner wall of a large-diameter pipeline, which mainly includes a mechanical arm bracket, a first joint of the mechanical arm, a secon...

AI Technical Summary

Problems solved by technology

The invention has the advantages of simple structure, flexible operation, and no blind spots in the spraying operation. A mechanical arm for spraying the inner wall of a large-diameter pipeline disclosed in this patent cannot finish coating the inner wall of the pipeline at one time, and the speed of segmental coating is slow, which seriously affects the efficiency of segmental coating. At the same time, during the stage coating process, the inner wall of the pipe is not protected, and it is easy to scratch the inner wall of the pipe, thereby reducing the reliability of use

[0004] However, the existing segmental coating equipment has great defects in the use process. The existing segmental coating equipment can finish the segmental coating of the inner wall of the pipeline at one time, and the speed of segmental coating is slow, which seriously affects the efficiency of segmental coating. At the same time, segmental coating During the coating process, the inner wall of the pipeline is not protected, and it is easy to scratch the inner wall of the pipeline, thereby reducing the reliability of use. The existing segmental coating equipment does not coat the silicone rubber segment evenly, which reduces the effect of segmental coating on the inner wall of the pipeline. At the same time, The silicone rubber coating for segmental coating cannot be continuously provided to the pipeline, which has poor durability. At the same time, the segmental coating on the inner wall of the pipeline is not thick enough. The existing segmental coating equipment cannot be automatically loaded, which reduces the convenience of use
