Abstract
The invention discloses a special auxiliary track device for in-service magnetic adsorption walking detection of pipelines. A plurality of arc-shaped steel plates are butted to form a round tube-type track, and the round tube-type track is wrapped outside a pipeline to be detected to provide an auxiliary creeping track for a magnetic attraction walking detection device; the magnetic attraction walking detection device is in close fit with the track, so that steady detouring of the magnetic attraction walking detection device in the circumferential direction of the pipeline to be detected is ensured; a detection probe on the magnetic attraction walking detection device can achieve automatic detection of detection parts, such as a circumferential butt-welded seam of the pipeline to be detected; the plurality of arc-shaped steel plates are connected and fixed through movable hinges, are foldable and are easy to mount and dismount. The special auxiliary track device is suitable for in-service detection of large-scale pipelines, such as an oil-gas transport pipeline, and is particularly suitable for in-service detection of non-ferromagnetic pipelines and pipelines with non-metallic coating layers.
