DETAILED DESCRIPTION

[0044] The four embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] First embodiment:

[0046] Figures 1-3Illustrated.

[0047] A coal mine tunnel supporting device and its using method, comprising a plurality of bases 1, a plurality of vertical support devices 2 are rotatably connected to the top of the bases 1, a plurality of shearing type support devices 3 are rotatably connected to the top of the vertical support devices 2, a hydraulic device 4 is rotatably connected to the top of the vertical support devices 2, anchor cable structures 5 are fixedly connected to the top of the vertical support devices 2 and the hydraulic device 4, a connecting rod device 6 is rotatably connected between the tops of the vertical support devices 2, a plurality of partitions 7 are fixedly connected to the top of the connecting rod device 6, and a plurality of pipelines 8 are fixedly connected between the partitions 7.

[0048] In the above coal mine tunnel supporting device and its using method, the supporting device provided by the scheme has good self-adaptability and can be flexibly adjusted according to the changes of the coal mine tunnel, and through the combined work of the hydraulic device 4 and the plurality of support devices, the pressure can be effectively dispersed to each support part, thereby enhancing the stability of the tunnel, and at the same time, the supporting device is convenient to install and disassemble, further improving the work efficiency and enhancing the work safety of the miners.

[0049] When the coal mine tunnel slightly changes, such as the top slightly sinking, the partitions 7 at the top of the supporting device will be moved downward under the pressure of the top of the coal mine tunnel, and the partitions 7 in turn move the hydraulic device 4 downward, because the anchor cable structures 5 are inserted into a higher stratum upward, so at this time the anchor cable structures 5 can firmly hold the stratum at a higher position of the top of the coal mine tunnel, so the anchor cable structures 5 generate a certain upward tension on the hydraulic device 4 and the vertical support devices 2, and in turn the hydraulic device 4 generates a thrust on the vertical support devices 2 along the horizontal direction of the cross section of the coal mine tunnel, so that the vertical support devices 2 move to the two sides of the coal mine tunnel, and in turn the vertical support devices 2 can better bear the pressure from the top and are not easy to collapse inward, at the same time, the shearing type support devices 3 and the connecting rod device 6 can disperse the pressure, so that the parts of the supporting device share the pressure, so that the supporting device is not easy to lose the supporting effect due to excessive local pressure, and at the same time, the plurality of pipelines 8 arranged at the top can provide air, water and other substances for the coal mine tunnel, without occupying too much space of the coal mine tunnel.

[0050] The base 1 provides a stable foundation for the support device, which can be adjusted stably when there is slight change, the vertical support device 2 reduces the influence of the top pressure on the roadway by supporting in the vertical direction, and when there is slight subsidence at the top, it can move to both sides of the mine roadway, thereby better bearing the pressure from the top and reducing the possibility of internal collapse, the shear support device 3 can disperse the pressure by cooperating with the vertical support device 2 when receiving the pressure, thereby reducing the failure of the support caused by excessive local pressure and enhancing the stability of the support, the hydraulic device 4 converts part of the pressure from the vertical direction to the horizontal direction by means of hydraulic pressure, so that the pressure can be evenly distributed in the entire support device, and when the top of the roadway subsides, it can generate upward tension to support the entire device, the anchor cable structure 5 is connected to a higher stratum, which can provide upward tension when there is slight subsidence, thereby stably supporting the hydraulic device 4 and the vertical support device 2, the connecting rod device 6 can disperse the pressure when the top subsides, so that the pressure of each part is shared, thereby reducing the failure of the support caused by excessive local pressure, the partition plate 7 will move downward after being subjected to the top pressure, thereby pushing the hydraulic device 4 to work and disperse the pressure, the pipeline 8 arranged at the top can provide necessary materials such as air and water for the coal mine roadway, and since it is arranged between the partition plates 7, it does not occupy too much space of the mine roadway, the design can flexibly adjust according to the change of the mine roadway through the cooperative work of various components, effectively disperses the pressure, enhances the stability of the roadway, improves the work efficiency, and improves the work safety of the miners.

[0051] Second embodiment:

[0052] Figures 7-8 shown.

[0054] When the top of the coal mine tunnel subsides slightly, the pressure from the first vertical support 205 and the second vertical support 206 is transmitted to the plurality of bases 101 and the crossbars 102 through the first support rod 201, the second support rod 202, the third support rod 203, and the fourth support rod 204. Because the tops of the four support rods are arc-shaped structures with convex surfaces facing the top of the coal mine tunnel, they can better adapt to the shape of the mine tunnel and provide more effective support. At the same time, because the first support rod 201 and the second support rod 202 are rotationally connected with the first shear rod 301 and the second shear rod 302, and the top of the third support rod 203 and the fourth support rod 204 is rotationally connected with the third shear rod 303 and the fourth shear rod 304, the first shear rod 301 and the second shear rod 302 are rotationally connected through the pivot, and the third shear rod 303 and the fourth shear rod 304 are rotationally connected through the pivot, forming a scissors-like structure that can stretch and contract when under stress, thereby dispersing the pressure to a larger area and enhancing the stability of the support. Because the scissors-like structure is rotationally connected around the pivot at the intersection, the connecting rods on the left and right sides will be spread out under the action of pressure, just like the opening of scissors. This outward movement will disperse the pressure to the left and right sides, reducing the pressure at a single point and increasing the stability of the structure. At the same time, due to the principle of leverage, it can effectively convert and transmit larger forces, further improving its ability to disperse pressure. In addition, due to the uniqueness of the structure of the scissors-like connecting rod, it also has a certain degree of flexibility, which can adapt to different space requirements and has high adaptability. This is especially important in environments such as coal mine tunnels, as the shape and size of the coal mine tunnel may change as mining operations progress. The scissors-like connecting rod can adapt to these changes by changing its shape, ensuring its continuous and effective support. The hydraulic device 4 is located on the first vertical support 205 and the second vertical support 206, and can be externally connected to a hydraulic pump to adjust the pressure and position of the first vertical support 205 and the second vertical support 206 in the horizontal direction, making it better adapt to changes in the coal mine tunnel. The anchor cable structure 5 is fixed to the top of the first vertical support 205 and the second vertical support 206, and can be securely connected to the upper part of the mine tunnel to provide additional support.

[0055] The various components work together to provide stable and effective support in the event of a roof collapse in a coal mine tunnel. The first vertical support 205 and the second vertical support 206 are directly subjected to the pressure of the mine tunnel roof and are adjusted by the hydraulic device 4 to adapt to changes in the shape and size of the mine tunnel. In the event of a slight roof collapse, these supports will adjust their position and pressure through the hydraulic device 4 to provide better support. The first support rod 201, the second support rod 202, the third support rod 203, and the fourth support rod 204 are arc-shaped at the top, which is adapted to the shape of the mine tunnel roof, thereby providing more effective support. These support rods transfer the pressure of the vertical supports to the multiple bases 101 and crossbars 102, dispersing the pressure and increasing the support area. The first shear rod 301, the second shear rod 302, the third shear rod 303, and the fourth shear rod 304 are connected to the respective support rods in a cross-shaped manner, forming a scissors structure. This structure can stretch and contract when under stress, dispersing the pressure to a larger area and increasing the stability of the structure. Through the principle of leverage, they can effectively transform and transmit larger forces, further improving their ability to disperse pressure. The hydraulic device 4 can adjust the horizontal pressure and position of the vertical supports 205 and 206 according to changes in the coal mine tunnel, allowing the support system to better adapt to changes in the coal mine tunnel. The anchor cable structure 5 is fixed to the top of the vertical supports and can be securely connected to the upper part of the mine tunnel, providing additional support.
