Device capable of polishing bent building steel pipe and fastener on bent building steel pipe

Abstract

The invention discloses a device capable of polishing a bent building steel pipe and a fastener on the bent building steel pipe. The device consists of an upper part and a lower part, the device can be arranged on the outer side of a pipeline which needs to be derusting and polished to be combined in a sleeving mode during working, the device can walk along the outer surface of the pipeline without manual operation, the device can derust and polish the outer surface of the pipeline while walking along the surface of the pipeline, the device can be separated from an adsorption state up and down when encountering blockage of the fastener so as to extend to cross over the fastener, the device can derust and polish the surface and the side surface of the fastener together when moving to the position above the fastener, polishing and derusting treatment on the outer side of the pipeline is greatly facilitated, the workload of a user is reduced, the device can turn to continue walking along the pipeline when encountering a bent pipeline, the derusting and polishing effect is better, meanwhile, automation of the treatment process is achieved, the treatment efficiency is greatly improved, and labor force is saved.

Description

technical field [0001] The invention relates to a device capable of grinding curved construction steel pipes and fasteners thereon, and mainly relates to the technical field of construction steel pipes. Background technique [0002] Steel pipes for construction can be divided into seamless steel pipes and seamed steel pipes according to the seamlessness of seams. Seam steel pipes are divided into spiral steel pipes and straight seam steel pipes according to different welds. The application of drainage and other aspects is very common. After a long time of use of construction steel pipes, a large amount of rust will be produced on the outer surface, which will affect the use effect. If the fasteners are not disassembled, the pipeline cannot be polished. If the fasteners are removed and cleaned, the workload of the workers will be increased, and they need to be reinstalled after disassembly, which is time-consuming and laborious. Moreover, the pipeline has bends, which cannot ...

[0002] Steel pipes for construction can be divided into seamless steel pipes and seamed steel pipes according to the seamlessness of seams. Seam steel pipes are divided into spiral steel pipes and straight seam steel pipes according to different welds. The application of drainage and other aspects is very common. After a long time of use of construction steel pipes, a large amount of rust will be produced on the outer surface, which will affect the use effect. If the fasteners are not disassembled, the pipeline cannot be polished. If the fasteners are removed and cleaned, the workload of the workers will be increased, and they need to be reinstalled after disassembly, which is time-consuming and laborious. Moreover, the pipeline has bends, which cannot be done well at this stage. Derusting and grinding treatment is carried out on the bending part of the steel pipe. In view of the above shortcomings, the present invention improves
