[0002] At present, track inspection robots have been widely used in various occasions. Generally, common inspection robots are usually provided with special tracks, and such inspection robots work on the special tracks. In some special large occasions, various pipelines, such as fire pipelines, are usually arranged. The fire pipelines are usually fixed in a suspended manner, and the suspended manner needs to hoist a hanger under the ceiling and then fix the pipeline on the hanger. At the same time, the fire pipeline has an interface, and the interface has a flange protrusion. In this way, the hanger and the flange will hinder the laying of the inspection robot track, resulting in great difficulty in laying the track and high cost.
