[0038] Among them, the adsorption component 103 includes an installation platform 103a disposed between the vehicle body 101 and the driving pan-tilt 104, and an electric propeller 103b disposed on the installation platform 103a. Among them, the rotation of the electric propeller 103b generates negative pressure, enabling the trolley to closely adhere to the coke oven wall 100.

[0039] Furthermore, the commutation device 106 includes a commutation component 106a disposed at the corner of the coke oven wall 100, and a commutation box body 106b rotatably disposed on the commutation component 106a.

[0040] Furthermore, the commutation component 106a includes a commutation platform 106a-1 disposed at the corner of the coke oven wall 100, a commutation frame 106a-2 disposed above the commutation platform 106a-1, an upper connecting member 106a-3 disposed between the commutation frame 106a-2 and the upper part of the commutation box body 106b, and a lower connecting member 106a-4 disposed between the commutation frame 106a-2 and the lower part of the commutation box body 106b.

Wherein, in this embodiment, a threaded rod passing through the lower sliding block 106a-4b is provided in the lower sliding track 106a-4a, and a power source disposed outside the reversing frame 106a-2 drives the threaded rod to rotate, and the threaded rod drives the sliding block to move in the lower sliding track 106a-4a through the thread.

[0043] The rest of the structure is the same as that of Embodiment 1.

[0044] Operation process: Place the wall-climbing trolley at the starting position on the coke oven wall surface, start the adsorption component 103 to firmly adsorb the trolley on the wall surface, start the trolley control system, the trolley moves on the wall surface along the predetermined path, conducts inspections section by section, and captures images and videos of the wall surface in real time. All the data collected by the sensors and cameras is transmitted to the remote monitoring center in real time through the wireless communication module. When the trolley reaches the reversing point, the reversing device 106 detects the position of the trolley through the inductor and conducts reversing. During the reversing process, the power source disposed outside the reversing frame 106a-2 drives the threaded rod to rotate, the threaded rod drives the lower sliding block to move in the lower sliding track through the thread, the lower sliding block drives the rotating rod to move, and the rotating rod drives the reversing box body 106b to change from being in contact with the original wall surface to being in contact with another adjacent wall surface.

[0045] Beneficial effects: The wall-climbing trolley can move flexibly along the coke oven wall and achieve efficient inspection through the preset inspection path, significantly improving the work efficiency compared with manual inspection, and is especially suitable for the continuous inspection tasks of large-scale coke ovens. It replaces manual operation and improves the safety of the inspection work.

[0046] Embodiment 3, refer to Figures 7 to 8, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a cleaning member 107, including a housing 107a disposed on the commutation table, a cleaning port 107b disposed on the commutation table, an air inlet 107c opened at the bottom of the cleaning port 107b, an electric rotor 107d rotatably disposed in the cleaning port 107b, a water spray port 107e disposed above the electric rotor 107d, and a filter 107f disposed between the housing 107a and the cleaning port 107b. Among them, in this embodiment, the camera is aligned with the cleaning port 107b through the pan-tilt for cleaning operations. The air inhaled through the air inlet 107c is filtered by the filter 107f disposed between the housing 107a and the cleaning port 107b to prevent dust and oil from entering the cleaning system and ensure clean air flow.

[0047] Operation process: When the trolley reaches the commutation point along the predetermined path, the commutation device detects the arrival position of the trolley through the built-in sensor. After the commutation device confirms the arrival of the trolley, it guides the trolley to stop in the preset cleaning area. The driving pan-tilt of the trolley adjusts the camera to the alignment position with the cleaning member to ensure that the camera can fully enter the cleaning assembly. The cleaning member starts the water gun nozzle to spray an appropriate amount of high-pressure water flow to wash the surface of the camera lens, removing the attached dust, oil and other pollutants. After the water gun washing is completed, the cleaning member starts the high-pressure gas nozzle to quickly blow off the residual moisture on the lens surface with a strong air flow to ensure that the lens surface is clean and dry. After the cleaning operation is completed, the commutation device starts the guide rail or the electric mechanism to smoothly guide the trolley to the adjacent wall surface.

[0048] Beneficial effects: The cleaning device cleans the omnidirectional camera to ensure that the monitoring effect is not affected by dust and oil.
