Rusty column reciprocating pneumatic rust removal and paint coating system and method

Abstract

The invention discloses a rusty column reciprocating pneumatic rust removal and paint coating system and method. The rusty column reciprocating pneumatic rust removal and paint coating system comprises pulling cables, a rust removal and paint coating sleeve, a hollow ring combination, an air pipe and a moving gear, wherein the pulling cables are tied up at the two ends of an iron pipe; a column body is sleeved with the rust removal and paint coating sleeve; the inner wall of the rust removal and paint coating sleeve is provided with a rust removal component and a paint coating component, and the rust removal component and the paint coating component can be used alternately to achieve the rust removal and paint coating functions; the hollow ring combination is arranged around the rust removal and paint coating sleeve; a liquid storage box is fixed to the upper portion of the hollow ring combination, and a waste storage box is fixed to the lower portion of the hollow ring combination; the air pipe is arranged above the rust removal and paint coating sleeve; one end of the air pipe is provided with a compressed air joint, and the other end of the air pipe is provided with an air expansion port; the moving gear is arranged on a hanger bracket through a bearing; the end of the bearing is fixedly provided with a spiral blade and is aligned with the air expansion port; tooth grooves are formed in the position, located at the moving gear, of the outer wall of the rust removal and paint coating sleeve; and the moving gear is engaged with the tooth grooves. The rusty column reciprocating pneumatic rust removal and paint coating system can achieve the rust removal and paint coating function on various types of rusty columns, and especially can achieve the safe and efficient dust removal and paint coating functions on underground iron pipes of gaseous mines or various types of aerial cables.

Description

Technical field [0001] The invention relates to the field of mechanical cleaning, rust removal and painting, in particular to a reciprocating pneumatic rust removal and painting system and method for rusted cylinders, and is particularly suitable for explosion-proof rust removal and painting of water pipes in mine tunnels or iron cylinders where construction is not easy. Derusting and painting areas of high-altitude cables. Background technique [0002] At present, many drainage pipelines are made of metal pipes. Due to the high humidity in the use environment, the drainage pipelines will quickly rust on the surface, and even rust and leak. If the rust is not removed in time, the drainage pipelines will leak. Leakage will inevitably cause waste of water resources and pollution of the surrounding environment. Premature maintenance and replacement of water pipes also increases costs and wastes resources. Especially the use of underground water pipes in gas mines is humid and dusty....

AI Technical Summary

Problems solved by technology

[0003] According to research, at present, most of the derusting of columnar bodies and cables is manual derusting and manual, and the efficiency is not high, especially when derusting such as high-altitude cables and underground water pipes in mines, it is extremely inconvenient due to the influence of the construction environment: on the one hand, the site environment Complex, difficult construction, low efficiency, can not achieve safe, efficient and quick automatic rust removal; on the other hand, especially for mines, the sparks generated by rust removal will cause gas and coal dust explosion, which brings great safety hazards to mine safety production , it is not easy to achieve safety and explosion-proof
