[0025] In one specific embodiment, a temporary support device for underground metal mine roadways includes a base plate 1, a plurality of vertical telescopic members 2 disposed on the upper surface of the base plate 1, an adjustment plate 4 disposed at the top of the vertical telescopic members 2, and an energy box 3 disposed on the upper part of the base plate 1. A placement box 6 is disposed on the top of the adjustment plate 4, and the energy box 3 is used to provide energy to the vertical telescopic members 2 and the placement box 6.

[0026] By setting a vertical telescopic component 2 on the base plate 1, installing an adjustment plate 4 on the top of the vertical telescopic component 2, setting a placement box 6 on the top of the adjustment plate 4, and setting an energy box 3 on the top of the base plate 1, energy can be provided to the vertical telescopic component 2 and the placement box 6, making them convenient to use. This facilitates the arrangement of temporary support devices for underground metal mine roadways. At the same time, the placement box 6 can store the temporary support devices for underground metal mine roadways that need to be placed. After use, the vertical telescopic component 2 can be lowered, and the entire device can be folded up for easy transportation and movement.

[0027] In this application, vertical telescopic components 2 are used to adjust the height of the relevant adjustment plate 4. The structure, telescopic method, control access, quantity and distribution are not limited. The vertical telescopic component 2 is a hydraulic rod vertical telescopic component 2 or a screw vertical telescopic component 2, or other types of vertical telescopic components 2. Preferably, the bottoms of multiple vertical telescopic components 2 are evenly distributed on the outer periphery of the base plate 1.

[0028] For example, in one embodiment, the base plate 1 is rectangular in shape, and a hydraulic rod is provided at each of the four corners of the base plate 1 as a vertical telescopic member 2.

[0029] Since the temporary support device for underground metal mine roadways in this application is a temporary support device, it needs to be easy to move and quick to deploy.
