Stepping type paint-spraying device for cylindrical inner walls

Abstract

The invention discloses a stepping type paint-spraying device for cylindrical inner walls. The stepping type paint-spraying device comprises a controller, a base, a nozzle, a nozzle supporting rod, a plurality of travelling devices driven by a stepping motor and a plurality of connecting rods, wherein a driving motor is fixed in the base, one end of the nozzle supporting rod is coaxially and fixedly connected with the output shaft of the driving motor, the nozzle is fixed at the other end of the nozzle supporting rod, one ends of the connecting rods are fixedly connected with the travelling devices, the other ends of the connecting rods are connected with the outer side of the base, and both the stepping motor and the driving motor are connected with the controller. The stepping type paint-spraying device for cylindrical inner walls has high paint-spraying efficiency, good paint-spraying uniformity and can be flexibly applied to various working conditions.

Description

[technical field] [0001] The invention relates to a paint spraying device, in particular to a step-by-step paint spraying device for the inner wall of a cylinder. [Background technique] [0002] Most of the pipelines that transport oil and natural gas are located in complex soil environments, and the media they transport are mostly corrosive, so the inner wall of the pipeline is easily corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt the transportation , and will pollute the environment, and may even cause fires and hazards. Therefore, preventing pipeline corrosion is an important content of pipeline engineering. Applying paint evenly and densely on the surface of the pipeline to isolate it from various corrosive media is one of the most basic methods for pipeline anticorrosion. However, the painting process in the prior art still has the following defects: 1. Manual spraying The way can be flexibly app...

[0002] Most of the pipelines that transport oil and natural gas are located in complex soil environments, and the media they transport are mostly corrosive, so the inner wall of the pipeline is easily corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt the transportation , and will pollute the environment, and may even cause fires and harm. Therefore, preventing pipeline corrosion is an important part of pipeline engineering

Applying paint evenly and densely on the surface of the pipeline to isolate it from various corrosive media is one of the most basic methods for pipeline anticorrosion. However, the painting process in the prior art still has the following defects: 1. Manual spraying The way can be flexibly applied to various working conditions, but it is easy to cause uneven spraying and low efficiency, and it is easy to affect human health; Poor performance, difficult to adjust
