| description | The utility model discloses a supporting device for coal mine machinery, which belongs to the technical field of coal mining, and adopts the technical scheme that the supporting device comprises a supporting frame, a machinery body is arranged on the inner bottom wall of the supporting frame, and limiting devices in contact with the machinery body are arranged on two sides of the inner wall of the supporting frame. The protection plate can effectively intercept falling rocks in a mine and prevent the falling rocks from damaging the mechanical body, and the first spring, the fixing frame and the connecting rod are combined for use, so that the impact force of the falling rocks can be effectively buffered, the protection plate is prevented from being damaged, the service life of the protection plate is prolonged, and the protection performance of the supporting device is better; and by arranging a limiting device, the mechanical body can be effectively clamped and limited, the situation that the mechanical body |
