The surfaces of the mounting seat (203) and the driving wheel (204) are both provided with an anti-slip layer.

8. The boiler water wall mechanical cutting equipment according to claim 7, characterized in that: The travel motor (200) is replaced with a transmission worm wheel (208), the upper side of the transmission worm wheel (208) is meshed with a worm (210), the worm (210) is rotatably arranged on a worm wheel frame (209), the worm wheel frame (209) is fixedly arranged on a mounting seat (203), and the worm wheel frame (209) is provided with a self-locking motor (207) for driving the worm (210) to rotate.

9. The boiler water wall mechanical cutting equipment according to claim 7, characterized in that: The clamping drive mechanism comprises a clamping motor (109) arranged at the center position of the bottom of the cutting bracket (100), two output ends of the clamping motor (109) are respectively connected to the clamping screw (108), each clamping screw (108) is provided with a clamping thread block (105) on the thread, both ends of the clamping thread block (105) are fixedly connected to the clamping guide rod (104), the outer end of the clamping guide rod (104) slides through the clamping guide sleeve (106) at the bottom of the cutting bracket (100), the end of the clamping guide rod (104) is connected to the mounting seat (203), and the bottom of the cutting bracket (100) is provided with a bottom bearing seat (107) rotatably connected to the end of the clamping screw (108).

10. A method for using the boiler water wall mechanical cutting device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Use the transport components to move the device to the target location, fix the device on the pipeline using the pipeline walking components, and then move it vertically along the pipeline; Step 2: When the vertical position is reached, the position of the cutting slide (300) is adjusted by the position adjustment component, so that the position of the cutting component (400) is further adjusted. Before cutting, the clamping transfer component is operated to clamp and fix the cut pipe, and then the cutting operation is performed by the cutting component (400); Step 3: After the pipe at the clamping position is cut, the steering motor (501) drives the steering shaft (502) to rotate, and the steering shaft (502) drives the clamping component (503) to rotate, and then the cut pipe is transferred to the loading frame (600) to prevent the cut pipe from falling, and then the next position is cut.
