Defect detection device for hazardous waste pipeline

The utility model discloses a hazardous waste pipeline defect detection device, which belongs to the technical field of pipeline detection equipment, and is characterized in that two groups of walking mechanisms and two groups of elastic supporting mechanisms are respectively assembled on two sides of a machine body, and two walking wheels of the walking mechanisms are pushed outwards through the elastic supporting mechanisms and are in rolling butt joint with the inner wall of a pipeline; meanwhile, the rolling abutting points are located on the inner wall of the pipeline above and below the axis plane of the pipeline, so that overall overhead walking of the detection device is achieved, on one hand, free walking in the hazardous waste pipeline especially at the corner can be achieved through the design mode, and on the other hand, influences of dirt deposited at the bottom in the pipeline are avoided; and the detection module at the front end of the overhead walking machine body basically coincides with the
