Track pipeline robot

The utility model belongs to the technical field of robots, particularly relates to a crawler pipeline robot, and aims to solve the problems that the distance between two crawlers cannot be adjusted according to the pipe diameter of a pipeline in the using process of an existing crawler pipeline robot for pipeline detection, so that the existing crawler pipeline robot cannot cope with pipelines with different pipe diameters, and the pipeline detection efficiency is high. In order to solve the problem that working cost is increased due to the fact that crawler pipeline robots of more specifications need to be purchased when pipelines with different pipe diameters need to be detected, the following scheme is provided, the crawler pipeline robot comprises two advancing crawlers, and the sides, close to each other, of the two advancing crawlers are fixedly connected with an L-shaped fixing plate and a second fixing plate correspondingly; the distance between the two advancing crawler belts can be adjusted by star
