[0083] When the hooking action is performed, the power unit 3 drives the device as a whole to move to the position of the airbag, and the drill bit 41 starts to work to drill the airbag. At the same time, the power unit 3 continues to drive the drill bit 41 to move forward until the drill bit 41 and the telescopic assembly 42 pass through the hole drilled by the drill bit 41 to the other side of the airbag. At the same time, when the walking frame 1 and the airbag are in contact, the power unit 3 stops working. At this time, the inner rod 422 extends under the action of the electric telescopic rod, driving the inner rod 422 to move back to the hook plate 43. The movement continues until the ejection member 434 is ejected from the ejection groove 436 of the sleeve 421, and the return hook plate 431 is pushed out and rotated to a certain angle. At this time, the inner rod 422 moves back under the action of the electric telescopic rod. At the same time, the return hook plate 431 is slowly opened during the return movement due to being ejected to a certain angle. When the inner rod 422 is completely returned to the airbag, a return hook-shaped claw is formed on the other side of the airbag, so that when the power unit 3 drives the device to move back as a whole, the airbag can be pulled back stably.

[0084] See also Figure 4 , the adjusting fixing member 223 includes:

[0085] The fixing grooves 2231 are evenly arranged on the supporting outer rod 221;

[0089] When adjusting the length of the support leg 22, press the pressing protrusion 2234 into the fixing groove 2231, and then pull out the supporting inner rod 222 to another fixing groove 2231. The pressing protrusion 2234 pops out again, and the adjusted length of the support leg 22 is re-fixed. Adjusting the length of the support leg 22 can make the overall device adapt to a wider range of pipe inner diameters.

[0095] The limit block 4352 is fixedly mounted on the rotating shaft seat 433 to limit the rotation angle of the rotating arc block 4351;

[0096] When the hook plate 431 rotates, the rotating arc block 4351 rotates along with the rotating shaft 432. When it rotates to 90 degrees, it will be abutted by the limit block 4352, thereby restricting the rotating shaft 432 from continuing to rotate, thereby limiting the maximum rotation angle of the hook plate 431.

[0097] As can be seen from the above, this embodiment arranges a support unit 2, a power unit 3 and a cleaning unit 4 on the walking frame 1, so that the airbag can be quickly positioned and removed. At the same time, a drill bit 41 and a hook assembly 43 are arranged in the cleaning unit 4, which can open the airbag and form a hook on the other side of the airbag to grasp the airbag over a large area, so that the airbag can be more firmly held during the pull-back and removal process, preventing the airbag from detaching from the cleaning unit 4.
