Description

Technical Field

[0001] The utility model relates to the field of pipeline maintenance equipment, in particular to a pipeline rust removal and painting equipment. Background Art

[0002] When transporting gas, liquid or installing cables, it is often necessary to set up corresponding pipelines in mid-air. Most of these pipelines are metal pipelines. After being exposed to the air for a long time, metal pipelines are prone to rust due to the peeling of the anti-rust layer. Therefore, regular maintenance is required, and the rust should be cleaned regularly and the anti-rust layer should be re-applied to avoid further damage to the pipeline.

[0003] However, the two ends of these pipes are mostly fixed on the wall or bracket and cannot be disassembled, so the existing pipe rust removal and grinding devices cannot be used. Therefore, the cleaning and maintenance of the pipes are mainly done manually, and there is only simple grinding and rust removal during the operation. Workers use brushes or rollers to paint, which cannot guarantee the complete removal of the rusted surface, and the paint is not evenly applied. The workers consume a lot of physical energy and have high labor intensity. In most cases, they work on ladders or brackets, which poses a safety hazard. This is an existing problem.
