A double-effect rust removal automatic sandblasting and rust removal equipment

Abstract

The invention discloses automatic sandblast rust removal equipment with double-effect rust removal and belongs to the field of pipe repaired mouth. The equipment includes two arc-shaped locating frames that are oppositely arranged, four arc-shaped opening and closing frames that are rotatably connected to the arc-shaped locating frames through rotation shafts, a first transverse travelling mechanism and floating type drive mechanisms that are arranged between two opposite arc-shaped opening and closing frames, and a closed type spray gun assembly that is disposed on the first transverse travelling mechanism. The equipment also includes an open type rust removal mechanism, wherein the open type rust removal mechanism includes a transverse bracket that is disposed on the outer side plate surface of the arc-shaped opening and closing frames and transversely extends, a second transverse travelling mechanism that transversely moves along with the transverse bracket, and an open type spray gun assembly that is disposed on the second transverse travelling mechanism. The equipment is suitable for closed type sandblast rust removal and open type sandblast rust removal.

Description

technical field [0001] The invention relates to the field of pipeline repairing, in particular to an automatic sandblasting and derusting equipment for double-effect derusting. Background technique [0002] In the oil and gas pipeline jointing process, in order to obtain good jointing quality, sandblasting and derusting treatment is usually carried out on the area of ​​the pipeline to be jointed before the jointing. Generally speaking, non-metallic sand is required for the repair of in-service pipelines The open sandblasting and derusting method is adopted for the section of the material, and the closed sandblasting and derusting method is adopted for the section of the pipeline under construction that is on-site anti-corrosion or requires the use of metal sand materials. Among them, open sand blasting and rust removal mostly use manual hand-held open spray gun components to spray non-metallic abrasives such as quartz sand, brown corundum, and garnet onto the surface of the ...

AI Technical Summary

Problems solved by technology

[0005] The automatic sandblasting and derusting equipment provided by the prior art is only suitable for closed sandblasting and derusting. For in-service pipelines, some sections must be closed for derusting, while some sections must be manually opened for derusting, so It affects the construction efficiency and it is difficult to guarantee the quality of rust removal
