Abstract
The utility model relates to a steel pipe piece anti-erosion spraying device for subway tunnel construction. The paint spraying groove is formed in the inner bottom of the L-shaped base and used for containing anti-erosion paint spraying, the recycling opening is formed in the top face of the horizontal end of the L-shaped base and communicated with the paint spraying groove, and the rotary table supporting assembly is rotationally arranged at the recycling opening, used for supporting the duct piece and provided with a gap facilitating falling of redundant paint spraying. The output end of the spraying assembly is vertically arranged on the face, right opposite to the two fixing assemblies, of the vertical end of the L-shaped base, and the spraying assembly is used for spraying anti-erosion paint in the paint spraying groove to the surface and the end faces of the two ends of the steel pipe piece. According to the utility model, through the cooperation of the rotatable turntable supporting assembly, the spraying assembly and the fixing assembly, anti-erosion paint spraying is carried out on each surface of a steel pipe piece while the steel pipe piece is fixedly rotated, so that automatic paint spraying is effectively realized without manual operation, and the manpower is greatly reduced.
