Dust removing device for outer surface of large-diameter steel pipe

Abstract

The invention discloses a dust removing device for the outer surface of a large-diameter steel pipe. The dust removing device comprises a worktable with supporting feet, a steel pipe fixing assembly fixed onto the worktable and driven by a driving assembly is arranged at the position, in the center of the worktable, of the upper part of the worktable, a dust removing assembly fixed onto the worktable is arranged above one side of the steel pipe fixing assembly, and a feeding assembly slidably connected to the worktable is arranged on the other side of the steel pipe fixing assembly. During using of the dust removing device, the steel pipe is placed in arc-shaped clamping grooves in telescopic plates, an air cylinder b drives a connecting plate to drive the telescopic plates to move to theposition under the steel pipe fixing assembly along sliding grooves b, the telescopic plates rise to enable one end of the steel pipe to be connected to the exterior of one of inserting-connecting rollers in a sleeving mode, an air cylinder a drives a movable plate to move along a sliding groove a, thus the other inserting-connecting roller is inserted into the other end of the steel pipe to fixedly clamp the steel pipe, a motor drives a gear to drive a gear ring to rotate, thus the steel pipe is driven to rotate, and the surface of the steel pipe makes contact with a dust removing sand rollerto generate friction for dust removing.

Description

technical field [0001] The invention relates to a large-diameter steel pipe outer surface derusting device, which belongs to the technical field of steel processing equipment. Background technique [0002] Steel pipe is a material that is widely used in industry and life. Steel pipes are generally placed outdoors in the open air, and corrosion is easy to occur on the surface. Large-diameter steel pipe is a common type of steel pipe. The current rust removal methods include chemical rust removal and physical rust removal. Chemical rust removal requires a large amount of chemical preparations, and the pollution is relatively large; physical rust removal is roughly There are two kinds of manual derusting and mechanical derusting. Manual derusting workers have high labor intensity and low efficiency. Mechanical derusting saves time and labor compared with manual derusting. However, the current mechanical derusting devices can only be used for fixed-length large-diameter steel pi...
