[0003] For example, a coal mine belt conveyor inspection robot with the authorization announcement number "CN219884922U" has a servo motor that drives the driving bevel gear to rotate. The driving bevel gear can drive the horizontal axis and the first bevel gear to rotate through the third bevel gear. At this time, the rotating first bevel gear drives the walking wheels to rotate synchronously through the second bevel gear and the main shaft, which makes it convenient for the main body to walk on the I-type track through the walking wheels, and is beneficial for the main body to drive the inspection camera to conduct real-time inspection of the belt conveyor. The load-bearing wheels and guide wheels in the auxiliary displacement mechanism are beneficial to improve the stability of the inspection robot's displacement movement and prevent the inspection robot from falling from the I-type track. However, since the position of the walking wheels of the coal mine belt conveyor inspection robot is fixed, it cannot walk on the I-track when other coal mine belt conveyors need to be inspected. The operator is required to switch to other compatible machines for inspection, which increases the limitations of the work. At the same time, since the angle of the camera of the coal mine belt conveyor inspection robot cannot be adjusted, the camera range is small, and the operator needs to conduct multiple inspections to complete the inspection work, which reduces work efficiency.

[0029] Working principle:

[0030] When using the inspection machine to inspect the coal mine belt conveyor:

[0031] Preparation process:

[0032] First, place the first roller 7 on both sides of the I-shaped track 6, and make the surface of the second roller 5 fit the surface of the I-shaped track. Figure 2 As shown, the power supply of the second motor 902 is started, and the second motor 902 rotates clockwise to drive the threaded rod 903 to rotate, thereby driving the slider 904 to move. The movement of the slider 904 causes the protruding part of the slider 904 to slide along the slide groove processed on the bent rod 905, thereby driving the bent rod 905 to swing. The swing of the bent rod 905 drives the rotating block 908 to slide along the surface of the bent rod 905. The movement of the rotating block 908 drives the cross bar 906 to slide along the surface of the second fixed column 907. At the same time, the cross bar 906 slides to the left along the through hole processed on the second shell 901. By controlling the output shaft of the second motor 902 to rotate counterclockwise, the bent rod 905 moves and drives the cross bar 906 to move to the right. When the cross bar 906 moves, it drives the protruding part of the first moving block 10 to slide along the slide groove processed on the fixed plate 11. When the surfaces of the two first rollers 7 are in contact with the surface of the I-shaped track 6, the power supplies of the two second motors 902 are turned off to realize an unused I-shaped track surface that can be installed, thereby reducing work limitations.

[0033] Coal mine belt conveyor inspection process:

[0034] Start the power supplies of the two first motors 8, and the output shafts of the two first motors 8 rotate in the same direction to drive the first roller 7 and the second roller 5 to move backward. When the output shafts of the two first motors 8 rotate in opposite directions, they drive the first roller 7 and the second roller 5 to move forward. When the angle of the camera 2 needs to be adjusted, start the power supply of the hydraulic cylinder 402, and the telescopic end of the hydraulic cylinder 402 moves to drive the protruding part of the rack 403 to slide along the surface of the first fixed column 404. The sliding of the rack 403 drives the first gear 405 and the second gear 406 to rotate. The rotation of the second gear 406 drives the rotating shaft 407 to rotate. The rotation of the rotating shaft 407 drives the second moving block 3 to rotate, thereby driving the camera 2 to rotate. The box body 1 can drive the camera 2 to perform real-time inspection of the working status of the coal mine belt conveyor, so as to realize that the operator does not need to perform multiple inspections, thereby improving work efficiency.
