Technical Field

[0001] The utility model relates to the technical field of coal mine inspection, in particular to a track mechanism for a coal mine inspection robot. Background Art

[0002] Coal mine inspection robots are automated devices that can replace manual inspections of equipment within coal mines. Due to the unique environment within coal mines, suspended inspection robots are often used for these inspections. Using suspended inspection robots requires installing suspended tracks within the coal mine tunnels. Existing suspended tracks typically consist of multiple small sections. However, the size and weight of these small sections make them difficult to install within the confined spaces of coal mine tunnels. Therefore, we propose a track mechanism for coal mine inspection robots. Summary of the Invention

The assembly plate 6 and the walking rail 14 are respectively installed on the outer surface of the assembly beam 2 through the assembly cavity 7. The assembly beam 2 and the assembly cavity 7 are respectively arranged in a corresponding triangular hollow shape. The inner surface size of the assembly cavity 7 matches the outer surface size of the assembly beam 2. The front end on both sides of the outer surface of the assembly cavity 7 provided on the lower surface of the assembly plate 6 and the rear end on both sides of the outer surface of the assembly cavity 7 provided on the upper surface of the walking rail 14 are provided with docking grooves 8, and the docking grooves 8 are respectively connected with the docking blocks 3 correspondingly;

[0024] An adjustment groove 9 is fixedly provided in the middle of the upper surface of the assembly plate 6, and an adjustment block 10 is installed on the assembly plate 6 through the inner surface of the adjustment groove 9.

[0025] When the present invention is in use, the several structures corresponding to the small track can first be transported to the coal mine tunnel. At this time, the adjustment block 10 in the adjustment groove 9 can be moved to the appropriate position for track installation, and the locking nut 12 sleeved on the outer surface of the locking screw 11 can be tightened to complete the fixation of the adjustment block 10.
