Problems solved by technology
[0003] 1. When using the coal mine roadway support bracket, because the height of the current roadway is different, the height of the support structure is also different, and the height of the current support structure is mostly fixed, so that the set support structure is applicable greatly reduced range
[0004] 2. The traditionally used coal mine roadway support bracket not only has low stability, but also cannot realize quick and convenient disassembly and installation between the supporting parts. When the support structure is not in use, it is not convenient for later collection and transportation

The invention relates to a coal mine safety protection device which comprises a base and a supporting mechanism, the supporting mechanism is arranged on the base, and the supporting mechanism comprises a hydraulic supporting plate, a first rectangular groove, a clamping groove, a supporting frame, an anchor net, a fixing block and a winding rod. Adjustment can be carried out at any time according to different heights of roadways needing to be supported, so that the use range of the device is greatly expanded, the device is rapid and convenient to mount and dismount and good in stabilizing effect, and when the device is not used, later collection and transportation are facilitated; the inner wall of the roadway can be simply protected, and potential safety hazards caused by falling of large coal blocks are avoided.
Description
technical field [0001] The invention relates to the field of coal mine safety protection, in particular to a coal mine safety protection device. Background technique [0002] In modern comprehensive mechanized mines, especially in coal mining, as the mining depth continues to increase, the geological conditions become more and more complex. Not only does the underground mine pressure increase, but some mining areas even experience unexpected rockbursts, resulting in serious personnel injuries. Casualties and property losses, in the roadway of excavation, the roadway needs to be supported, so it is necessary to use the coal mine roadway support bracket, the general support method is divided into permanent support and temporary support, the present invention is aimed at the temporary support structure design. [0003] 1. When using the coal mine roadway support bracket, because the height of the current roadway is different, the height of the support structure is also differe...
