Derusting and polishing device for outer surface of steel pipe

Abstract

The invention discloses a derusting and polishing device for the outer surface of a steel pipe. The device comprises a rack part (1), a polishing part (2), a polisher locking mechanism (3), a rack locking mechanism (4), a guide rail part (5) and a reciprocating mechanism (6); a high-speed motor drives a steel wire brush to rotate for polishing and derusting the outer surface of the steel pipe, and the reciprocating mechanism (6) drives the polishing part (2) to rotate around a shaft of the steel pipe in a reciprocating manner to achieve the purposes of derusting and polishing the outer surface of the whole circumference of the cylindrical steel pipe; the device is suitable for steel pipes with different diameters due to the adjustable structure; the device is convenient and quick to mount and dismount due to the arrangement of the polisher locking mechanism (3) and the rack locking mechanism (4). The device can be applied to derusting and polishing of the outer surfaces of cylindrical metal guard railings and suspended metal pipelines in public places.

Description

technical field [0001] The invention relates to a rust removal and grinding device for the outer surface of a steel pipe Background technique [0002] Stairs, balconies or aisles in public places are often equipped with metal tubular protective railings. Metal materials are prone to rust, making the railings unsightly. Severe rust will also destroy the firmness of the railings, causing serious safety hazards and economic loss. In order to reapply the rust-proof decorative paint, the rust layer must first be removed. There are various rust removal tools or equipment on the market. The most common is traditional manual rust removal using simple sandpaper or power tools. The advantage of the traditional method is comprehensive rust removal, but the labor intensity of the operator is high; the shot blasting machine is bulky, inconvenient to operate, and lacks flexibility. One person cannot complete the loading and unloading actions and cannot remove the fixed railings. rust;...

AI Technical Summary

Problems solved by technology

The advantage of the traditional method is comprehensive rust removal, but the labor intensity of the operator is high; the shot blasting machine is bulky, inconvenient to operate, and lacks flexibility. One person cannot complete the loading and unloading actions and cannot remove the fixed railings. rust; sand blasting consumes a lot of energy and easily causes dust pollution, and it is difficult to complete large-scale rust removal; there is also high-pressure water spraying, which wastes water resources and is not convenient for large-scale rust removal. The surface is rusted again

Another method is to use chemical reagents, but the cost is very high and the impact on the environment is also great
