A rolling coating device for automatic tube turning and loading and unloading of mine coating tubes

Abstract

The invention relates to an automatic turning tube loading and unloading roller coating device for mining coating pipes, which includes a square plate, support feet, support plates, guide plates, a paint box, a lifting mechanism and a turning mechanism. The invention can solve the problem of mining coating pipes During the processing operation, due to the heavy weight of the steel pipe itself, it is difficult to realize the automatic loading and unloading of the steel pipe in the plastic coating, and it is easy to cause impact damage to the device during the placement of the steel pipe, which increases the work intensity of manual work and The loss strength of the plastic coating device makes it difficult to clamp and position the steel pipe in the circumferential direction, which increases the probability of tilting and shaking of the steel pipe during rolling coating, and makes it difficult to evenly apply the plastic coating to the outer wall of the steel pipe, reducing the adhesion of the plastic coating. , it is more difficult to keep the plastic coating in a flowing state all the time, which increases the problem of uneven coating density in various areas on the steel pipe due to the precipitation of the plastic coating.

Description

technical field [0001] The invention relates to the technical field of processing plastic-coated steel pipes, in particular to an automatic pipe-turning and unloading roller coating device for mining coated pipes. Background technique [0002] Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces. Plastic-coated steel pipes have excellent corrosion resistance and relatively small frictional resistance; among them, epoxy resin-coated steel pipes are suitable for the transportation of water supply and drainage, sea water, warm water, oil, gas and other media, and PVC-coated steel pipes are suitable for drainage , seawater, oil, gas and other media transportation, mine coated pipe refers to the plastic co...

AI Technical Summary

Problems solved by technology

[0003] 1. During the steel pipe plastic coating operation, due to the heavy weight of the steel pipe itself, it is difficult to realize the automatic loading and unloading of the steel pipe in the plastic coating, and it is easy to cause impact damage to the device during the placement of the steel pipe, which increases the manpower The working intensity of the work and the loss intensity of the plastic coating device;

[0004] 2. In the process of steel pipe plastic coating, it is difficult to clamp and position the steel pipe in the circumferential direction, which increases the probability of tilting and shaking when the steel pipe is rolled, and it is difficult to make the steel pipe rotate at a uniform speed and apply the plastic coating evenly If it is attached to the outer wall of the steel pipe, the adhesion efficiency of the plastic paint is reduced, and it is more difficult to keep the plastic paint in a flowing state, which increases the phenomenon of precipitation of the plastic paint, which leads to uneven paint density in various areas on the steel pipe
