Automatic sand blasting and derusting system on inner wall of pipeline

Abstract

The invention discloses an automatic sand blasting and derusting system on the inner wall of a pipeline. The automatic sand blasting and derusting system comprises a traveling crane hoisting mechanism, two metal boxes, a steel pipe locating and rotating mechanism, a track, a sand blasting mechanism, two sand collecting tanks, two dust removal ducts, an automatic control computer and a detection device. The automatic sand blasting and derusting system on the inner wall of the pipeline can be applied to the sand blasting and derusting construction of the inner wall of a metal pipeline having the pipe diameter of 350-2,500 mm and the length of 1-15 m. A spray gun of the system is automatically located in the center; a gun head is rotated; the system is provided with the detection device, an operation radius of the gun head can be adjusted according to a pipeline caliber; the spray gun and a sand tank are integrally pushed by an automatic program; sand collecting and pouring processes are automatic; the steel pipe is mechanically dismounted and transported; the construction efficiency of the whole production line is high; the automatic sand blasting and derusting system can be widely applied to pipeline anticorrosion and derusting in the fields of municipal engineering, petrochemical engineering and the like.

Description

technical field [0001] The invention relates to rust removal of metal pipelines, in particular to an automatic sand blasting rust removal system for inner walls of pipelines. Background technique [0002] The existing steel structure anti-corrosion field, especially the heavy-duty anti-corrosion field, is not highly automated. Sandblasting and painting in the workshop are mostly manual operations. Sand dust and paint flying dust are extremely harmful to the human body and the environment. How to improve labor efficiency? It is an important problem to be solved to improve productivity, improve production quality, and reduce harm to human body. Contents of the invention [0003] The object of the present invention is to provide an automatic sand blasting and derusting system for the inner wall of the pipeline in order to solve the above-mentioned problems in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical so...
