Steel pipe inner wall derusting machine

Abstract

A steel pipe inner wall derusting machine, comprising a fixed seat, an extending mechanism fixed horizontally on the fixed seat, a driving device fixed on the extending mechanism, and a rust remover driven by the driving device; device; the extension mechanism is composed of several detachably connected extension tubes, the driving device includes a motor installation tube fixedly connected with the extension mechanism, and a motor is fixed inside the end of the motor installation tube away from the fixed seat, and the motor and the control device Electrically connected, the rust remover is fixedly set on the output shaft of the motor; the rust remover includes a base fixedly set on the output shaft of the motor, and several miniature hydraulic cylinders are evenly fixed on the base. It is electrically connected with the control device, and a cutting head is fixedly arranged on the output end of each miniature hydraulic cylinder. The invention provides a rust remover for the inner wall of a steel pipe, which can completely remove rust without leaving any dead angle, and can be applied to steel pipes with different pipe diameters and different lengths.

Description

technical field [0001] The invention relates to the field of pipeline processing equipment, in particular to a steel pipe inner wall derusting machine. Background technique [0002] Pipes such as steel pipes and cast iron pipes are widely used in the technical fields of petroleum, chemical industry, water supply and drainage, power stations, papermaking, leather, ventilation and extraction of corrosive gas chimneys in my country. However, steel pipes and cast iron pipes are good conductors of electricity. During storage and use, local battery reactions will occur due to chemical and electrochemical effects, and the surface is easily rusted, which often pollutes the conveying medium. Therefore, special anti-rust and rust-removing treatments are often required on the surface. [0003] In the past, when derusting the inner wall of steel pipes, shot blasting derusting machines or flexible shafts and grinding wheels were usually used. The shot blasting derusting machine used need...

AI Technical Summary

Problems solved by technology

The shot blasting derusting machine used needs to establish a separate derusting operation line. The equipment needs a large number of accessories such as a separate sand supply device and a sand return device, which cannot be used alone. The efficiency of the derusting operation is low, and the structure itself is huge. Both are very cumbersome and expensive. For a long time, a lot of manpower, material and financial resources have been wasted in the process of derusting the inner wall of steel pipes.

However, the method of using a flexible shaft to drive the grinding wheel for rust removal has a certain degree of randomness in the process of rust removal, which may cause local wear or partial cleaning.
