[0042] A support block 12, the support block 12 is fixedly connected to the upper side of the spring 13;

[0043] The top plate 9 is fixedly connected to the upper end of the threaded rod 2 .

[0044] In the specific embodiment of the utility model, the support rod 1 is used to provide basic supporting force. The threaded rod 2 is threadedly connected to the threaded hole 15 and adjusted to the specified position, so that the support rod 1 and the threaded rod 2 can be spliced, and the threaded rod 2 can be rotated to adjust to an appropriate height. The first ring 5 and the second ring 7 are respectively placed in the groove 16 so that the support plate 6 is located in the U-shaped plate 8, and will not leave the inside of the U-shaped plate 8 when the threaded rod 2 is rotated and adjusted. After the height adjustment of the threaded rod 2 is completed, the spring 13 and the support block 12 cooperate to abut against the lower end of the support plate 6 to increase the supporting area and make the threaded rod 2 stable without shaking. The top plate 9 completes the top closure and support of the equipment. The height of the support device is fine-tuned by rotating the threaded rod 2 to achieve the best supporting effect, which is convenient for disassembly and assembly. At the same time, it does not take up a large space when personnel install it, which increases the stability of the support. The overall structure is simple, easy to install and maintain, and improves the safety and efficiency of mine construction.

[0045] For details, please refer to Figure 1-Figure 2 The circumferential surface of the support rod 1 is fixedly connected with a bracket 3, and the bracket 3 is a solid structure.

[0049] For details, please refer to Figure 1-Figure 4 The circumferential surfaces of the support rod 1 and the threaded rod 2 are both sleeved with rubber rings 10, and the two rubber rings 10 are fitted together.

[0050] In this embodiment: the rubber ring 10 helps to reduce the vibration and noise of the device during use, and can also increase the friction between the support device and the formation to enhance stability. The two rubber rings 10 fit together to reduce vibration and increase stability.

[0051] For details, please refer to Figure 1 The upper end of the top plate 9 is adhesively connected with a friction block 17.

[0052] In this embodiment, the friction block 17 enhances the friction force between the contact surface of the top plate 9 and the top of the mine, which helps to improve the stability and safety of the support device.

[0053] For details, please refer to Figure 4 A bevel groove 11 is formed at the upper end of the top plate 9 , and a limit stopper 14 is fixedly connected to the inner walls of both sides of the bevel groove 11 near the end.

[0054] In this embodiment, two groups of inclined grooves 11 are provided, and the inclined grooves 11 are used for docking with other equipment. At the same time, the limit stopper 14 can prevent the supporting legs from penetrating, thereby playing a protective effect.

[0055] The working principle and use process of the utility model are as follows: when mining construction is required, the device is placed at the location where construction is required. By rotating the threaded rod 2, the top plate 9 can move up and down to adapt to different environmental requirements. At the same time, the spring 13 drives the support block 12 to extend and retract to provide stable supporting force for support plates 6 of different heights, thereby ensuring the safety of construction. It will not take up a large space when personnel install it, which increases the stability of the support. The overall structure is simple, and installation and maintenance are convenient, thereby improving the safety and efficiency of mining construction.
