Then, install and position the finished protection equipment at the braking working position through the bearing base. Finally, connect the control mechanism to the external power system to complete the equipment assembly.

[0032] When the invention is in use, when the machine is in a shutdown state or does not need to be protected, the bearing columns are adjusted to be parallel to the upper end surface of the bearing base through the restaurant mechanism, and the protective baffle connected to the bearing columns is covered outside the upper end surface of the bearing base, while effectively reducing the equipment space occupancy rate and improving the space utilization rate of the construction environment, the bearing base, the turning mechanism and other parts can also be effectively protected through the protective baffle; when the protective operation is needed, the bearing columns are adjusted to be vertically distributed with the bearing base through the turning mechanism, and the working height of each bearing column is adjusted according to the needs, and the surface of each protective baffle is adjusted to face the working surface to be protected through the bearing column, so that when rockfall occurs, the falling gangue is blocked and protected by the protective baffle, and the angle formed between the two bearing plate surfaces in the same protective baffle is used to guide the blocked gangue, reduce the damage to the equipment caused by the impact force of the gangue, and assist in the targeted guidance and collection of the falling gangue, thereby improving the flexibility and reliability of use.
