[0049] (2) Equipment positioning

[0050] After checking that everything is correct, the staff will move the tunnel floor drum repair equipment to the designated work area to ensure that the equipment can move in the tunnel; since the tunnel floor is uneven, an area is first determined as the working surface; the floor drum repair work is carried out based on this working surface; after arriving at the designated work area, the staff confirms the exact location that needs to be repaired.

[0051] (3) Working arm preparation

[0052] After confirming the repair position, the staff controls the rotating chassis 300 and the sliding mechanism 400 through the remote control device to move the working arm 200 from Figure 2 The non-operating position shown above the vehicle body 100 is adjusted to Figure 1 The working position shown is located on one side of the vehicle body 100, and the milling head 220 is moved to a determined position. According to the size of the tunnel bottom drum, the milling depth and width are set and the angle and position of the milling head 220 are adjusted to align it with the tunnel bottom drum area to start the milling operation.

[0053] (4) Perform bass drum repair work

[0054] During the milling process, the load force and the repair progress are monitored in real time by sensors, and the milling parameters are adjusted to ensure efficient repair. During the milling process, the remote control device continuously controls the milling head 220 to ensure that it works according to the predetermined path; the slag generated during the milling process will be collected by the spiral feeding mechanism and transported to the drop port 211 through the mechanism. At this time, the slag will fall from the drop port 211 onto the scraper conveyor 500, and then be transported by the scraper conveyor 500 to the working surface scraper conveyor or mine car. After completing the collection of the slag, the staff controls the crawler walking system to move forward through the remote control device to repair the next target bottom drum. After arriving at the target area, the rotary chassis 300 is continued to be controlled through the remote control device to rotate the working arm 200, so that the spiral drive member of the spiral feeding mechanism drives the spiral body and the milling head 220 to continue to move, and the milling and collection of the slag is completed. During the whole process, the staff constantly controls the status and work progress of the equipment through the collected data, and makes timely adjustments according to the actual situation on site.

[0055] (5) Repair completion and waste disposal

[0056] After the repair is completed, the milling is stopped, and the staff retracts the working arm 200 through the remote control device, and moves the working arm 200 from the milling state to a position above the vehicle body 100. The final state is as follows: Figure 2 shown.

[0057] (6) Equipment evacuation and inspection

[0058] After retracting the working arm 200 to the specified position, the staff controls the crawler walking system through the remote control device to move the equipment to a safe area. The staff performs necessary maintenance and inspection on the equipment to ensure that it can operate normally in the next operation.

[0059] In summary, the present embodiment provides a tunnel bottom drum repair device, and the rotating chassis 300 of the working arm 200 has two states: flat and vertical.
