[0029] The lifting assembly can be adjusted in height and can be applied to tunnels of different heights, thus expanding the scope of application. The top of the lifting assembly is provided with an inclined support 5 and a top plate 6, which is convenient for disassembly and installation, and is also convenient for transportation. The inclined support 5 has a better bearing effect, can decompose the vertical force, and relieve the pressure on the ground; the shock-absorbing assembly greatly reduces the interference caused by vibration and strengthens the protective effect, and the reinforcement assembly further fixes the whole, making the whole more stable; the top support adopts an arc support plate 11, which has a good force bearing effect and is suitable for the arc surface at the top of the tunnel; the connecting tube 22 is used to connect with another device, which is convenient for disassembly and assembly, and the distance between adjacent devices can be adjusted by increasing or reducing the number of cross bars and connecting tubes 22, and the scope of application is wide; the setting of the telescopic assembly can strengthen the support effect on the side, and the telescopic assembly can adjust the length so that the side support plate 12 is only fitted with the side wall of the tunnel, which is suitable for tunnels of different widths. The present invention can be applied to different coal mine tunnels, has strong adaptability, and has a more stable and reliable structure and good support effect.

[0030] Further optimization scheme, the reinforcement assembly includes a second shock absorbing plate 21 fixed to the top surface of the column 7, a plurality of first reinforcement rods 8 are fixed to the top surface of the second shock absorbing plate 21, a second reinforcement rod 10 is arranged above the first reinforcement rod 8, the first reinforcement rod 8 and the second reinforcement rod 10 are arc-shaped rods, a plurality of cross rods 9 are fixed at equal intervals between adjacent first reinforcement rods 8 and second reinforcement rods 10, and a shock absorbing assembly is installed on the top of the second reinforcement rod 10.

[0031] A further optimized solution is that the shock absorbing assembly includes a plurality of first shock absorbing plates 16 circumferentially fixed to the top of the second reinforcement rod 10, a sleeve 17 is fixed to the top surface of the first shock absorbing plate 16, a damping rod 19 is slidably connected in the sleeve 17, the top of the damping rod 19 extends out of the sleeve 17 and is fixed to a pad 20, the pad 20 is fixed to the bottom surface of the arc-shaped support plate 11, a shock absorbing spring 18 is sleeved on the outer side of the damping rod 19, the bottom of the shock absorbing spring 18 is fixed to the sleeve 17, and the top of the shock absorbing spring 18 is fixed to the pad 20. The damping rod 19 can slide in the sleeve 17, and hydraulic oil is sealed in the sleeve 17. When vibration occurs, the damping rod 19 slides downward to squeeze the hydraulic oil in the sleeve 17 to perform a certain shock absorption and buffering. At the same time, the damping rod 19 and the outer shock-absorbing spring 18 are used in conjunction with each other to also play a buffering role, reduce the vibration effect, and enhance the protection of the interior of the tunnel; the pad 20 is convenient for providing a fulcrum for the damping rod 19 to prevent damage to the arc-shaped support plate 11. The first shock-absorbing plate 16 is used to receive the second reinforcement rod 10 and the sleeve 17, and at the same time plays a certain shock absorption function, thereby improving the overall protection performance.

[0032] Further optimization scheme, the telescopic assembly includes a fixed rod 14 fixed to the side wall of the oblique support 5, and the end of the fixed rod 14 away from the oblique support 5 is slidably connected with a threaded sleeve 13, and the threaded sleeve 13 is rotatably connected to the side support plate 12. When supporting the side of the tunnel, the threaded sleeve 13 is rotated to slide outward relative to the fixed rod 14 until the side support plate 12 fits the side wall of the tunnel, and then continues to rotate to tighten. The side protection can be strengthened through the side support plate 12, and there is a certain angle between the fixed rod 14 and the oblique support 5, the load-bearing performance is good, and the protection effect is improved.

[0033] Further optimization scheme, the end of the fixed rod 14 away from the oblique support 5 extends into the threaded sleeve 13 and is fixedly connected with a screw 24, the screw 24 is threadedly connected with the inner wall of the threaded sleeve 13, and the end of the screw 24 away from the fixed rod 14 is installed with a compression spring 26, and the end of the compression spring 26 away from the screw 24 is fixedly connected with a baffle 27, and the baffle 27 is fixedly connected with the inner wall of the threaded sleeve 13.

After adjusting to the appropriate position, the compression spring 26 gives the baffle 27 and the screw 24 opposite thrusts, so that the side support plate 12 fits more tightly with the side of the tunnel to prevent loosening, and further enhance the support effect.

[0034] In a further optimized solution, a groove 31 is provided on the side of the screw rod 24 away from the fixed rod 14, a gasket 25 is rotatably connected in the groove 31, a plurality of balls 32 are embedded in the groove 31, the balls 32 fit the gasket 25, and the side of the gasket 25 away from the screw rod 24 is fixedly connected to the end of the compression spring 26.

After the device is organized, the jack 2 is started to lift the whole device until the support plate of the unit is just in contact with the inner top surface, which is convenient for height adjustment and suitable for coal mines of different sizes, expanding the scope of application.
