[0016] In order to ensure the stability of the pipe body 1 when moving in the pipeline, there are three moving devices.
[0017] The sandblasting tube 14 is connected with a sandblasting machine.

[0019] When the utility model is in use, during the pipeline anti-corrosion processing, it is necessary to perform sandblasting on the inside of the pipeline. According to the different diameters of the pipeline, sponge strips 4 of different thicknesses are pasted on the outer edge surface of the disc 3, so that the sponge strips 4 are in contact with the inner wall of the pipeline, and then the sleeve 13 is rotated. The threads of the first screw rod 9 and the second screw rod 12 are rotated in opposite directions. The first screw rod 9 and the second screw rod 12 are threadedly connected with the sleeve 13 at the same time.
