[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. In the actual mining process, for a coal mining face, it is often necessary to support the coal seam above the working face through an auxiliary support device to prevent the coal seam from falling and injuring coal miners or equipment due to water penetration or excessive pressure. In order to improve the mobility of the hydraulic support, the existing hydraulic support is usually equipped with a roller mechanism at the bottom. When supporting, it is anchored through an anchor, and then the anchor needs to be removed when moving, which is very cumbersome. Content of the Utility Model

[0003] In view of this, the technical problem to be solved by the utility model is to provide a mining hydraulic support device, which can quickly switch between the moving mode and the working mode, greatly improving the work efficiency; at the same time, it can adapt to uneven roads and further improve the stability performance.

[0020] To better understand the technical content of the present utility model, specific embodiments are provided below, and the present utility model will be further described in conjunction with the accompanying drawings.

[0021] Referring to Figures 1 to 4 , the present utility model provides a support device for a mining hydraulic support, including a base 1, a support top plate 2 and a hydraulic mechanism 3. The support top plate 2 is connected to the top of the base 1 through the hydraulic mechanism 3. Support feet 4 are provided at the four corners of the bottom of the base 1. Moving mechanisms for driving the entire support device to move are respectively provided on both sides of the bottom of the base 1. Lifting mechanisms for driving the moving mechanisms to move up and down are provided on both sides of the base 1. The lifting mechanisms are connected to the moving mechanisms one by one. A leveling mechanism for adjusting the height is provided inside the support feet 4.

[0022] When the support device is in the moving mode, the bottom ends of the support feet 4 are located above the moving mechanisms. At this time, the support feet 4 do not contact the ground, which facilitates driving the support device to move through the moving mechanisms; when the support device moves below the support surface and switches to the working mode, the lifting mechanisms are started to drive the moving mechanisms to rise until the bottom ends of the moving mechanisms are located above the support feet 4. At this time, the moving mechanisms do not contact the ground, and the stability of the support device is improved by the contact of the support feet 4 with the ground. Compared with the method of installing or removing anchor bolts, the present device can quickly switch between the moving mode and the working mode, greatly improving the work efficiency; at the same time, when the working road surface is uneven, the leveling mechanism can adjust the lengths of the support feet 4 to adapt to the uneven road surface and further improve the stability performance of the support device.

[0023] The moving mechanism includes a moving base 19 and rollers 20. The rollers 20 are installed on both sides of the bottom of the moving base 19. The lifting mechanism is connected to the moving base 19, and the supporting device is driven to move through the moving base 19 and the rollers 20.

[0024] The lifting mechanism includes a lifting screw rod 5, a sliding rod 6, an internally threaded cylinder 7, and a driving component for driving the rotation of the internally threaded cylinder 7. The internally threaded cylinder 7 is installed inside the base 1 and is rotatably connected to the inner wall of the base 1. The base 1 is provided with a through hole for the lifting screw rod 5 to pass through, and the through hole communicates with the center of the internally threaded cylinder 7. The lifting screw rod 5 passes through the through hole and is threadedly connected to the center of the internally threaded cylinder 7. The bottom of the lifting screw rod 5 is fixedly connected to the top of the moving base 19. The sliding rod 6 is slidably inserted through both sides of the moving base 19, and the top of the sliding rod 6 is fixedly connected to the bottom of the base 1. The lowest point of the sliding rod 6 is above the lowest point of the support feet 4.

[0025] The driving component includes a main gear 8, a sub-gear 9, and a transmission wheel 10. The main gear 8 is fixedly sleeved on the circumferential outer wall of the internally threaded cylinder 7. A rotating shaft 11 is provided inside the base 1, and both ends of the rotating shaft 11 are rotatably connected to the inner wall of the base 1. The sub-gear 9 and the transmission wheel 10 are sleeved on the rotating shaft 11 one above the other. The sub-gear 9 is meshed and connected to the main gear. The transmission wheels 10 on both sides are connected by a transmission chain. A cavity is provided inside the base 1, and the main gear 8, the sub-gear 9, and the transmission wheel 10 are all installed in the cavity. A rotating disk 12 and a connecting shaft 13 are provided on the top of the base 1, and the connecting shaft 13 is coaxially connected to any one of the rotating shafts 11. The center of the rotating disk 12 is fixedly connected to the top of the connecting shaft 13.

[0026] When it is necessary to raise the moving mechanism to stably support the device, the staff rotates the rotating disk 12 to drive the connecting shaft 13 and the rotating shaft 11 to rotate. The rotating shaft 11 then drives the transmission wheel 10 and the sub-gear 9 to rotate synchronously. The sub-gear 9 drives the internally threaded cylinder 7 to rotate through the main gear 8. Since the lifting screw rod 5 is fixedly connected to the moving base 19, and both sides of the moving base 19 are slidably connected to the sliding rod 6 up and down, the lifting screw rod 5 cannot rotate. In the case of the rotation of the internally threaded cylinder 7, the lifting screw rod 5 can only move up and down in the vertical direction along the sliding rod 6, thereby driving the moving mechanism to rise or fall. Under the linkage action of the transmission wheel 10 and the transmission chain, the moving mechanisms on both sides can be lifted and lowered synchronously, avoiding the situation that the moving mechanisms on both sides are at different heights, resulting in the imbalance of the support device.

[0027] The leveling mechanism includes a leveling screw 14, a bottom plate 15 and a leveling knob 16. A threaded through-hole is provided at the center of the support foot 4, and the threaded through-hole extends to communicate with the top of the base 1. The leveling screw 14 is threadedly connected to the threaded through-hole. The bottom plate 15 is located below the support foot 4 and is connected to the bottom of the leveling screw 14. The leveling knob 16 is connected to the top of the leveling screw 14. By driving the leveling screw 14 to rotate with the leveling knob 16, the distance that the leveling screw 14 extends out of the bottom of the support foot 4 can be controlled, effectively adapting to uneven road surfaces.

[0028] A guiding mechanism is further provided between the base 1 and the support top plate 2. The guiding mechanism includes a guiding sleeve 17 and a guiding rod 18. The guiding sleeve 17 is installed on both sides of the top of the base 1, and the guiding rod 18 is installed on both sides of the bottom of the support top plate 2. The guiding rod 18 is slidably connected to the center of the guiding sleeve 17, and the guiding sleeve 17 and the guiding rod 18 play a guiding role in the support top plate 2.

[0029] The hydraulic mechanism 3 is a hydraulic cylinder, and the piston head of the hydraulic cylinder is connected to the center of the bottom of the support top plate 2.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
