[0002] When mining in a mine, various machines are needed. Since the heights of various places in the mine are not uniform, the position of the mining machinery needs to be constantly adjusted as the mining work proceeds. Therefore, a support device is needed to support part of the mining machinery and adjust the height of the mining machinery so that it can run smoothly.

[0003] However, the existing mechanical support devices for mines still have the following shortcomings: 1. The existing mechanical support devices for mines cannot adjust the height and cannot be flexibly adjusted according to the height of the working environment, resulting in poor flexibility; 2. The interior of most mines is relatively uneven, and the existing mechanical support devices for mines are not stable enough, prone to displacement, and have poor use effects. Therefore, we propose a mining mechanical support device that is convenient for adjusting the height. Utility Model Content
