The design purpose of this device is to ensure that the loading machine is stably supported on the working face, and at the same time, it allows its height to be adjusted according to the actual working conditions to adapt to different working environments and load changes.

The output ends of the auxiliary hydraulic cylinder I and the auxiliary hydraulic cylinder II are respectively hinged to the fixed seats arranged on the pressure column cylinder, so as to support the pressure column cylinder in the left-right direction. However, in this way, only the left-right single direction of the pressure column cylinder can be supported, and the front-back direction of the pressure column cylinder cannot be supported. For the working conditions that require fine adjustment in multiple directions, the lack of support in the front-back direction will reduce the adaptability of the equipment, and more pressure column cylinders are needed to support the bridge-type loading machine, increasing the complexity and difficulty of operation.
