Description
technical field [0001] The invention relates to the technical field of ultrasonic non-destructive flaw detection equipment and facilities, in particular to an in-pipe crawling robot used for pipeline flaw detection. Background technique [0002] In the petrochemical field, it is often necessary to perform flaw detection on pipelines to detect cracks or defects inside the pipelines. However, a large number of pipelines are buried underground, and it is impossible to dig out all the pipelines for inspection during the flaw detection process. Therefore, it is necessary to use a crawling robot in the pipe to carry flaw detection equipment. Into the inside of the pipeline to perform flaw detection on the pipeline. [0003] However, the motion structure of the crawling robot in the pipe in the prior art is relatively complicated, and because the environment in the petrochemical pipeline is relatively harsh, the pipeline wall often adheres to chemical raw material residues, impurit...
