Damage-free detection special pipeline automatic oxide skin polishing device and method thereof

Abstract

The invention discloses a damage-free detection special pipeline automatic oxide skin polishing device and a method of the damage-free detection special pipeline automatic oxide skin polishing device. The problems that damage can be caused to a pipeline wall due to manual polishing and the efficiency is low are solved. The automatic oxide skin polishing device comprises at least two sets of annular guiding rails which are arranged outside a pipeline to be detected in a sleeved mode, a door-shaped polishing frame, a horizontal sliding device and a polishing machine. The door-shaped polishing frame is installed on the annular guiding rails and rotates in the circumferential direction along the pipeline to be detected. The horizontal sliding device which can move back and forth relative to a beam is installed on a beam of the door-shaped polishing frame. The polishing machine is installed on the horizontal sliding device through an elastic connecting part and driven by a motor. When the polishing machine works, the elastic connection part can make a polishing wheel of the polishing machine keep in contact with the face, to be polished, of the pipeline to be detected. According to the damage-free detection special pipeline automatic oxide skin polishing device and the method of the damage-free detection special pipeline automatic oxide skin polishing device, the pipeline can be polished automatically, polishing quality is ensured, potential safety risks are eliminated, labor intensity of workers is reduced and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of engineering applications, and relates to an automatic grinding device and method for non-destructive testing of pipeline oxide scales, which are suitable for grinding before non-destructive testing of pipelines. Background technique [0002] The surface of the in-service pipeline needs to be polished before non-destructive testing, so that it can expose the metal to meet the testing requirements. At present, the surface treatment of the pipeline is mainly performed by manual grinding. This grinding method is expensive in labor and grinding. The efficiency is low. At the same time, there is a great risk of mechanical damage during grinding, and there are great safety hazards. Therefore, it is urgent to solve the problem of in-service pipeline grinding. Contents of the invention [0003] In order to overcome the disadvantages of the existing manual grinding that may cause damage to the pipeline wall and have low ef...
