[0024] During operation, through the installation of the liquid cylinder 23 and the plunger 24, when the whole needs to be limited and fixed on the pipeline, the rubber track 31 can be connected and fitted with pipelines of different specifications, which is conducive to making corresponding changes for pipelines of different diameters.

[0025] Furthermore, the mounting frame 1 is provided with two first fixing rings 11, and connecting blocks 12 are movably provided at both ends of the first fixing rings 11, and the other sides of the two connecting blocks 12 are fixedly connected with second fixing rings 13;

[0026] During operation, the whole is divided into two parts by the first fixing ring 11 and the second fixing ring 13. When fixing, the first fixing ring 11 is connected to the connecting block 12 by the connecting seat 14, and the whole is installed around the pipeline.

[0027] Furthermore, one side of the two first fixing rings 11 is fixedly connected to a connecting seat 14, a fixing rod 21 is fixedly installed between the two connecting seats 14, a movable groove 26 is opened on one side of the fixing rod 21, and a movable block 25 is movably installed on one side of the movable groove 26;

[0028] During operation, the fixing rod 21 is fixed by connecting the first fixing ring 11 to the connecting seat 14 . When the movable block 25 moves, the movable groove 26 limits the movement of the movable block 25 .

[0029] Furthermore, a fixing plate 15 is fixedly connected between the two connecting blocks 12, a protective shell 16 is fixedly connected to the bottom of the fixing plate 15, a main board 18 is installed inside the protective shell 16, an industrial camera 17 is fixedly installed on the top of the main board 18, and a searchlight 19 is fixedly installed on one side of the main board 18;

After fixing, the stepping motor 32 is driven to transmit the rubber track 31, so that the rubber track 31 is close to the pipeline and drives the whole to move.
