Derusting device

Abstract

The invention relates to a derusting device, which mainly comprises a jacking device, a body, a derusting wheel and a transmission control device, wherein the jacking device comprises a tip cone, a locking block, a clamping block, a self-locking block and a stopping block. A derusting rod is jacked by the tip cone and locked by matching the locking block and the clamping block. Self-locking and control are realized by matching the locking block, the self-blocking block and the stopping block. The body has a frame structure and comprises a rack and a plurality of guide rails. The derusting wheel is formed by winding a plurality of strands of steel wire balls and has a disk shape and elasticity. The transmission control device comprises a control box and a plurality of motors. The derusting rod derusts a metal rod by controlling rotation of the derusting wheel, translation of the derusting wheel and rotation of the derusting rod. The derusting device cannot only derust metal pipes with steps or metal rods with steps, but also is suitable for derusting transverse upright rods in building industry, the derusting efficiency is high, a derusting dead corner is avoided, a good derusting effect is achieved, and the derusting device is convenient to operate and can be operated by a common worker.

Description

technical field [0001] The present invention relates to a derusting device, in particular to a derusting device for a metal pipe with a step or a metal rod with a step, and more particularly to a derusting device for a bowl-type horizontal pole in the construction industry. Background technique [0002] Existing rust removal methods for the outer surface of metal rods, metal pipes or metal rods include pickling and mechanical rust removal. The effect of pickling and rust removal is relatively good, but it is easy to produce a large amount of waste acid, which seriously pollutes water bodies, soil, etc., and also has certain corrosion on the rust-removed bar or rod material. Mechanical derusting methods are more commonly used, and generally can be divided into manual derusting and electric derusting. Manual rust removal is labor-intensive, and the rust powder and dust emitted during the rust removal process seriously pollute the environment and endanger the health of the ope...

Chinese patent CN200710065040.4 discloses a "oil pipe outer wall derusting device", and CN200810124011.5 discloses a "locomotive axle derusting machine", but these derusting devices are not suitable for metal pipes or metal rods with steps For rust removal, the structure is more complicated

The technical solution provided by the above-mentioned patents is difficult to derust the bowl-type horizontal pole. The main reasons are as follows: first, there is a buckle bowl in the middle of the horizontal pole, which is similar to steps, and it is difficult for general derusting machinery to apply; The two ends and the buckle bowl are prone to rust removal dead ends
