It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a mining support device, including two fixed plates 1, the outer surfaces of the two fixed plates 1 are fixedly connected with a lifting mechanism 3, the bottoms of the two fixed plates 1 are fixedly connected with a fixing mechanism 4, the lifting mechanism 3 includes two mounting plates 301, two driving motors 302 are arranged on the opposite sides of the two mounting plates 301, the output ends of the two driving motors 302 slide through the outer surfaces of the two mounting plates 301 and extend to one side, the output ends of the two driving motors 302 are fixedly connected with two connecting shafts 303, the outer surfaces of the two connecting shafts 303 are fixed Two gears 304 are fixedly connected, and the outer surfaces of the two gears 304 are meshedly connected to two racks 305. The opposite sides of the two racks 305 near the upper position are fixedly connected to two fixed blocks 306. The opposite sides of the two fixed blocks 306 are fixedly connected to two movable plates 307. The tops of the two movable plates 307 are fixedly connected to a top beam rod 308. The outer surfaces of the two mounting plates 301 are fixedly connected to the outer surfaces of the two fixed plates 1. The top of the top beam rod 308 is fixedly connected to a support column 309, and the top of the support column 309 is fixedly connected to an arc top rod 310.

[0023] The effect achieved by the entire embodiment 1 is that when the mining support device is used for height adjustment, first, by starting the driving motor 302 on the mounting plate 301, its output end begins to drive the connecting shaft 303 connected thereto to rotate, and as the connecting shaft 303 rotates, the gear 304 thereon also begins to rotate synchronously, and since the gear 304 and the rack 305 are meshingly connected, the rotation of the gear 304 directly drives the rack 305 to move up and down, and the lifting action of the rack 305 further drives the synchronous lifting of the fixed block 306 fixed thereto, and the lifting action of the fixed block 306 makes the movable plate 307 connected thereto slide in the preset fixed plate 1. The groove 2 slides accordingly, thereby realizing the height adjustment of the entire support device. Subsequently, with the upward movement of the movable plate 307, the top beam rod 308, the support column 309 and the arc top rod 310 connected thereto also move upward in conjunction, thereby ensuring that the arc top rod 310 can closely fit the environment of the mining top and effectively support the mining space to achieve the supporting effect. Under the action of the lifting mechanism 3, the limitation of fixed support is avoided, and the flexible adjustment of the support height is realized, so that the device can flexibly adapt to the support requirements of different mining environments, thereby ensuring the smooth progress of mining operations, reducing the safety hazards caused by improper support, and improving operation safety.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the fixing mechanism 4 includes two connecting plates 401, and a plurality of screw rods 402 are arranged at the tops of the two connecting plates 401 near the four corners. One end of the plurality of screw rods 402 is threadedly penetrates the tops of the two connecting plates 401 and extends to the bottom, and one end of the plurality of screw rods 402 is fixedly connected with a plurality of conical columns 403. The tops of the two connecting plates 401 are fixedly connected to the bottoms of the two fixing plates 1, and the tops of the two fixing plates 1 are provided with two sliding grooves 2, and the inner surface walls of the two sliding grooves 2 are slidably connected to the outer surfaces of the two movable plates 307.

[0025] The effect achieved by the entire embodiment 2 is that when using the mining support device, it will first be inserted into the mining environment through the conical column 403, and penetrate into various strata through the shape of the conical column 403 and contact the surrounding environment. Then, by twisting the screw rod 402, the conical column 403 can be firmly fixed in the mining environment, ensuring the stability of the device during the support process and preventing support failure caused by shaking or displacement of the device. The connecting plate 401 is mainly used to connect the conical column 403.

[0026] Working principle: When in use, by starting the driving motor 302, the connecting shaft 303 connected thereto is driven to rotate. As the connecting shaft 303 rotates, the gear 304 thereon also starts to rotate synchronously. Since the gear 304 and the rack 305 are meshed and connected, the rotation of the gear 304 directly drives the rack 305 to move up and down. The lifting action of the rack 305 further drives the synchronous lifting of the fixed block 306 fixed thereto. The lifting movement of the fixed block 306 makes the movable plate 307 connected thereto slide accordingly in the sliding groove 2 in the preset fixed plate 1, thereby realizing the whole The height of the support device is adjusted. Then, as the movable plate 307 rises, the top beam rod 308, the support column 309 and the arc top rod 310 connected thereto also move upward in conjunction, thereby ensuring that the arc top rod 310 can closely fit the environment of the mining top and effectively support the mining space to achieve a supporting effect. Then, through the conical column 403, it is inserted into the mining environment, and through the shape of the conical column 403, it penetrates into various strata and contacts with the surrounding environment. Then, by twisting the screw 402, the conical column 403 is firmly fixed in the mining environment, ensuring the stability of the device during the support process.
