Grinding and rust removing device for chemical pipeline anticorrosion

Abstract

The invention discloses a grinding and rust removing device for chemical pipeline anticorrosion. The grinding and rust removing device for chemical pipeline anticorrosion comprises an operation frame.A first guide rod and a second guide rod are horizontally and fixedly mounted in the operation frame. The first guide rod and the second guide rod are slidably sleeved with an upper sliding sleeve and a second sliding sleeve correspondingly. Grinding heads are fixedly mounted at the ends of telescopic rods correspondingly. A rotary shaft is rotatably arranged on the right sidewall of the operation frame. The rotary shaft is in transmission connection with a second lead screw through a second transmission belt. An output shaft of a forward and reverse rotating motor is coaxially fixed to the second lead screw. According to the grinding and rust removing device, the forward and reverse rotating motor rotates forwards and reversely to drive a first lead screw and the second lead screw to rotate, and then a first threaded sleeve and a second threaded sleeve drive the telescopic rods to do left-right reciprocating motion. Finally, the grinding heads do transverse back and forth motion to grinding the surface of a pipeline. The grinding speed is increased. Meanwhile, the pipeline can rotates along with rotating of the fixed plates so as to be annularly ground. The working efficiency isgreatly improved.

Description

technical field [0001] The invention relates to the technical field of pipeline anticorrosion and derusting, in particular to a grinding and derusting device for chemical pipeline anticorrosion. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Due to its unique characteristics, pipelines are widely used in many industries and fields. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] Before installation and use, chemical pipelines need to be polished and derusted on the surface. The rust stains on the surface will continue to corrode the pipeline and affect the service life of the pipeline. Most of the current steel pipe grinding methods are manually polished, and the grinding efficiency is low....

[0003] Before installation and use, chemical pipelines need to be polished and derusted on the surface. The rust stains on the surface will continue to corrode the pipeline and affect the service life of the pipeline. Most of the current steel pipe grinding methods are manually polished, and the grinding efficiency is low. The removal of rust stains is not fast enough, and the labor load is large
