Description

Technical Field

[0001] The utility model relates to the field of equipment used in metal mineral mining, and more specifically, to a supporting device. Background Art

[0002] In the process of mining metal minerals, it is often necessary to dig caves in the mine. When mining metal minerals in the caves, due to the different geological conditions of the caves, support devices are often required to support the top and side walls of the caves to prevent the top or side walls of the caves from collapsing, causing harm to the mining personnel and affecting the mining of minerals. Existing support devices generally support the top and side walls of the caves through ceilings and side panels, and at the same time protect the space inside the entire device through the ceiling and side panels to prevent the fallen rocks from entering the support device. However, the side panels of the existing support devices are often fixedly connected to the entire device. When it is necessary to mine the minerals on the side walls of the cave, it is inconvenient to remove the side panels so that the construction personnel can contact the side walls of the cave. In addition, the existing support devices generally only use a single-layer protective structure, which has limited protection against falling stones, and falling stones can easily cause damage to the support structure, resulting in a loss of support effect.

[0015] (III) Beneficial effects

When it is necessary to protect the side wall of the cave, the first baffle is installed between the two supporting legs by bolts, and the second baffle is installed on the first baffle through the cooperation of the protruding block and the movable groove. Since the length of the second baffle is longer than the first baffle, when it is necessary to mine the side wall of the cave, the bolts of the connecting plate and the connecting hole opened on the first baffle are taken out, so that the limit on the second baffle disappears, and the second baffle is made perpendicular to the first baffle.

[0018] 2. The utility model sets a first baffle, a second baffle and a shielding plate. When the side wall of the cave is prone to collapse, the limit plate is taken out from the limit hole. Due to the rotational connection between the shielding plate and the top frame, the shielding plate remains naturally vertical due to gravity. The first baffle and the second baffle are kept parallel, and bolts are inserted into the limit holes to fix the position of the second baffle. The moving position of the shielding plate is limited by the second baffle. The first baffle and the shielding plate cooperate to form a first layer of side plate structure, and the second baffle forms a second layer of side plate structure, thereby facilitating effective protection of the cave side wall and reducing the damage to the inside of the support device caused by falling rocks.
