[0018] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0019] The present invention has a reasonable design. When conducting internal inspection of a high-pressure gas pipeline, first ensure that the inspection device is pushed in from one end of the pipeline, and is installed at one end of the pipeline through the pipeline sealing cover on the surface of the pull rope disc. At the same time, the high-pressure gas pipeline is re-supplied with gas. At this time, the outrigger cylinder contracts, driving the sliding sleeve to move on the surface of the sliding rod, and then driving the movable support arm to push the swing wheel to turn outward on the surface above the three mounting buckles.
