A steel pipe derusting machine

Abstract

The invention relates to a steel pipe derusting machine, which comprises a frame, and an end limiting device is arranged on the frame. The end limiting device includes an annular mounting seat and a guide ring. The inner surface of the guide ring includes an annular surface and an arc-shaped Concave surface, the end limit device also includes a limit ring, which is provided with at least four guide holes, and a compression column is installed in the guide hole, and the inner end of the compression column is pressed against the outer peripheral surface of the steel pipe, and the compression The outer end of the column is against the inner peripheral surface of the guide ring, the guide ring is fixedly installed with a support rod, the guide wheel is rotated on the support rod, and a connecting rope is arranged between the guide wheels of the limit device at both ends, and the connecting rope is connected with a The rust removal brush on the outer wall and the rust removal brush on the inner wall, the part of the connecting rope located on the outside of the steel pipe is facing the arc-shaped concave surface. When the compression column touches the arc-shaped concave surface, the compression column does not press against the outer peripheral surface of the steel pipe, and the connecting rope can pass through the steel pipe And the gap between the compression column can realize the simultaneous derusting of the inner wall and outer wall of the steel pipe.

Description

Technical field [0001] The present invention relates to a steel tube remover. Background technique [0002] The existing rusting equipment is only possible to remove the outer wall of the steel pipe, or only the inner wall of the steel pipe and the inner wall of the steel pipe and the outer wall of the steel pipe cannot be achieved at the same time. Inventive content [0003] The technical problem to be solved by the present invention is to provide a steel pipe removal rust in which the steel pipe inner wall defensive rust and the outer wall of the steel pipe is higher. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a steel pipe removal machine, including a frame, the frame having an end limit device clamping both ends of the steel pipe, the end limit device Including a ring mount, the annular mounting seat is rotated mounting a guide ring, the axis of the guide ring and the axis of the ring mount, the inner surface o...
