[0036] Working principle:

[0037] First, when the protective structure of the support device 1 for coal mining machines is in the initial state, the support assembly 3 is distributed at the four corners of the bottom surface of the support plate 4, the pressure dividing column 35 is in the initial position, and the drive block 32 slides smoothly on the slide rail 2 through the pulley. After starting the drive motor 31, it drives the drive block 32 to move, and the extrusion block on the bottom surface of the drive block 32 is in close contact with the ground to provide support force. When the height needs to be adjusted, the two sets of high-torque hydraulic rods in the hydraulic press push the adjustment column 34 up or down, and the pressure dividing column 35 is adjusted accordingly and tightly inserted into the limiting steel cylinder 33. At the same time, the drive block 32 slides smoothly on the slide rail 2, driving the support plate 4 to move to the specified position. In this process, the limiting column keeps the drive motor 31 stable, the anti-slip plate 321 prevents slipping, and the pressure dividing column 35 plays a role in balancing and dispersing pressure to ensure the safe operation of the entire device. At this point, the entire workflow ends.
