Steel pipe derusting machine

Abstract

The invention relates to a steel pipe derusting machine. The steel pipe derusting machine comprises a rack, end limiting devices are arranged on the rack, each end limiting device comprises an annularmounting base and a guide ring, the inner surface of the guide ring comprises an annular face and an arc-shaped concave face, each end limiting device further comprises a limiting ring, at least fourguide holes are formed in the limiting ring, pressing columns are movably mounted in the guide holes, the inner ends of the pressing columns are pressed on the outer circumferential face of a steel pipe, the outer ends of the pressing columns abut against the inner circumferential face of the guide ring, a supporting rod is fixedly installed on the guide ring, a guide wheel is rotatably installedon the supporting rod, a connecting rope is arranged between the guide wheels of the end limiting devices and connected with an outer wall derusting brush and an inner wall derusting brush, and a part, located on the outer side of the steel pipe, of the connecting rope directly faces the arc-shaped concave face. When the pressing column makes contact with the arc-shaped concave face, the pressingcolumn does not abut against the outer circumferential face of the steel pipe, the connecting rope can pass through a gap between the steel pipe and the pressing column, and simultaneous derusting ofthe inner wall and the outer wall of the steel pipe can be achieved.

Description

technical field [0001] The invention relates to a steel pipe derusting machine. Background technique [0002] The existing derusting equipment can only derust the outer wall of the steel pipe, or only the inner wall of the steel pipe, and cannot simultaneously derust the inner wall of the steel pipe and the outer wall of the steel pipe, and the derusting efficiency of the steel pipe is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel pipe descaling machine which can realize the descaling of the inner wall of the steel pipe and the outer wall of the steel pipe at the same time, and has a high descaling efficiency. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a steel pipe derusting machine, including a frame, and the frame is provided with end limiting devices clamped at both ends of the steel pipe, and the end limiting devices It includes...
