[0026] In summary, if Figures 1 to 4As shown, when the pipe bevel cutting device that can crawl along the pipe wall is used, the pipe that needs to be beveled is first structurally fixed, and then the whole device is placed on the surface of the pipe, and the adsorption component 2 at the bottom of the self-propelled vehicle 1 is started. Under the operation of the main control vehicle body 101, a certain amount of power is provided to the second electromagnetic block 205 and the first electromagnetic block 203 through the control cable 206, so as to generate electromagnetic adsorption force. At the same time, with the assistance of the movable shaft frame 202 at the bottom of the stabilizing frame 201 and the structural activity of the connecting hinge 204, the first electromagnetic block 203 and the second electromagnetic block 205 are as close to the outer surface of the pipe as possible.

[0027] Then, the combustible material to be cut is transported by using the quick connector 402 on one side of the valve seat 401, and is transported through the transmission hose 403 and the structure of the connecting valve head 505 to the inside of the cutting nozzle 504 for subsequent operation;

[0028] Then, the first screw rod 304 and the second screw rod 306 are respectively screwed in the horizontal direction and the vertical direction, so that the moving column 303 connected to the first screw rod 304 and the sliding block 501 connected to the second screw rod 306 are respectively moved and adjusted in the horizontal direction and the vertical direction along the support rod 302 on one side of the support pile 301, the surface of the first screw rod 304, and the surface of the guide rail 305 and the second screw rod 306, so as to adjust the position of the cutting assembly 5 that needs to be processed;

[0030] As the cutting nozzle 504 starts to cut the groove of the pipe, the self-propelled universal wheel 103 at the bottom of the lifting column 102 will start to operate slowly and evenly with the appropriate electromagnetic adsorption force provided by the operation of the adsorption component 2 to rotate in coordination with the processing of the cutting nozzle 504, and start to slowly crawl along the surface of the pipe, thereby achieving the circular cutting processing effect until the processing is completed.
