Description

Technical Field

[0001] This utility model relates to the field of mining technology, and specifically to a mining support device. Background Technology

[0002] In mining engineering, the use of support devices plays a crucial role in ensuring mine production safety and improving mining efficiency. As mining depths increase, the stability of underground roadways and working faces becomes increasingly prominent, placing higher demands on the performance of support devices. This is especially true for deeper deposits or when mining reaches a certain depth, necessitating underground mining methods. At this point, various pathways must be drilled between the surface and the ore body for ore transportation, ventilation, drainage, personnel access, and other necessary preparatory works for new ore extraction by metallurgical equipment.

[0003] In existing technologies, mining operations typically rely on support devices to ensure the stability of the working face. However, traditional support devices are often limited by their fixed nature, making it impossible for them to flexibly adjust their height. This limitation makes it difficult for support devices to adapt to diverse mining environments. When faced with mining requirements at different heights, traditional support devices cannot reach the specified height to meet the on-site support needs, making the devices unable to provide sufficient support, which may lead to safety hazards and reduce operational safety. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a mining support device that solves the problem that the mining process cannot flexibly support the mine tunnel according to the needs of the mine tunnel.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mining support device, comprising two sets of left and right support legs, each support leg comprising an upper support rod and a lower hydraulic telescopic rod, the hydraulic telescopic rod comprising a base, and an adjustment handle for controlling the raising and lowering of the hydraulic telescopic rod is provided on the base; The top of the support rod is hinged to a support arm, and the two sets of support arms are slidably connected in a cross manner. A fixing mechanism is set at the intersection point so that the two sets of support arms can jointly support the top of the mine shaft.

[0006] Optionally, the top of the left support rod is hinged to a first support arm, and the top of the right support rod is hinged to a second support arm. A groove extending along the first support arm is formed on the first support arm, and the second support arm is adapted to pass through the groove. A limiting block is provided at the end of the second support arm that passes through the groove, and the width of the limiting block is greater than the width of the groove.

[0007] Optionally, both the first and second support arms have several sets of modular holes along their extension direction, and corresponding connecting screws are provided. The connecting screws pass through the modular holes of the first and second support arms that are aligned at the intersection, and the ends of the connecting screws are locked with matching nuts.

[0008] Optionally, the limiting block is a cylindrical slider.

[0009] Optionally, both the first and second support arms are curved.

[0010] Optionally, a number of sets of tapered pins are fixed to the bottom of the base.

[0011] Optionally, the hydraulic telescopic rod is multi-stage telescopic.

[0012] This utility model provides a mining support device, which has the following beneficial effects: This utility model provides a mining support device. By fixing legs on both sides of the mine shaft, and then using support arms above the legs for cross-fitting, the support arms can move in an arc shape above the legs because they are hinged to the top of the legs. A groove extending along the first support arm is opened on the first support arm, and a second support arm fits through the groove. The two sets of support arms are cross-set, allowing them to slide left and right to adapt to the width of the mine shaft. The two sets of support arms are then fixed into a whole by a fixing mechanism. The combined support of several sets of support devices can ensure the support strength of the mine shaft, solving the technical problem that the mine shaft cannot be flexibly supported according to the needs of the mine shaft during the mining process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1 to 3 This utility model provides a technical solution: a mining support device, including two sets of support legs 1, each support leg 1 including an upper support rod 2 and a lower hydraulic telescopic rod 3. The hydraulic telescopic rod 3 is multi-stage telescopic, adaptable to different mine shaft heights. The hydraulic telescopic rod 3 includes a base 4, with several sets of conical pins 6 fixed to the bottom of the base 4, ensuring the hydraulic telescopic rod 3 is firmly fixed to the mine shaft floor. The base 4 is equipped with an adjustment handle 5 for controlling the lifting and lowering of the hydraulic telescopic rod 3, facilitating the adjustment of the telescopic height of the hydraulic telescopic rod 3. The top of the support rod 2 is hinged to a support arm, and the two sets of support arms are slidably connected in a cross manner, with a fixing mechanism at the intersection point, so that the two sets of support arms jointly support the top of the mine shaft. The first support arm 11 and the second support arm 12 are both arc-shaped, facilitating the formation of an appropriate support structure at the top of the mine shaft. The hydraulic telescopic rod 3 at the bottom of the support leg 1 can be adjusted to adapt to the height of the mine shaft, and the cross-shaped support arms at the top of the support leg 1 can be slidably adjusted to adapt to the left and right width of the mine shaft, thereby solving the technical problem of not being able to flexibly support the mine shaft according to the needs of the mine shaft during the mining process.

[0017] In this embodiment, as a preferred option, the top of the left support rod 2 is hinged to the first support arm 11, and the top of the right support rod 2 is hinged to the second support arm 12. A groove 101 extending along the first support arm 11 is formed on the first support arm 11. The second support arm 12 is adapted to pass through the groove 101. A limiting block 21 is provided at the end of the second support arm 12 that passes through the groove 101. The two sets of support arms slide crosswise, so that the end of the second support arm 12 is supported on the arm of the first support arm 11, and the end of the first support arm 11 is supported on the arm of the second support arm 12, thereby forming a stable support structure that relies on each other. The limiting block 21 is a cylindrical slider, which facilitates the sliding of the limiting block 21 on the arm of the first support arm 11. The width of the limiting block 21 is greater than the width of the groove 101 to prevent the second support arm 12 from detaching from the groove 101 of the first support arm 11.

[0018] In this embodiment, as a preferred solution, after the first support arm 11 and the second support arm 12 are cross-fitted, they are connected and fixed by a fixing mechanism. The first support arm 11 and the second support arm 12 each have several sets of modular holes 102 along their own extension direction, and corresponding connecting screws 9 are provided. The connecting screws 9 pass through the modular holes 102 that are cross-aligned between the first support arm 11 and the second support arm 12, and the end of the connecting screw 9 is locked with a matching nut 8, so that the first support arm 11 and the second support arm 12 are connected as a whole, ensuring stable support for the top of the mine.

[0019] In this invention, the working steps of the device are as follows: 1. Fix the left and right support legs 1, and insert the conical pins 6 at the bottom of the left and right support legs 1 into the ground of the mine shaft; 2. The left and right support arms slide in a cross manner. Adjust the cross sliding of the left and right support arms according to the condition of the top of the mine so that the intersection of the two sets of support arms is in the appropriate position. 3. Fix the connecting screw 9, and lock it in place using the connecting screw 9 and nut 8 through the module holes 102 corresponding to the positions of the first support arm 11 and the second support arm 12, so that the left and right support arms are fixed as a whole; 4. Raise outrigger 1 by using the adjusting handle 5 to extend the hydraulic telescopic rod 3, raising the height of outrigger 1 until the top of the support arm reaches the top of the mine shaft. 5. Install several sets of support devices at intervals in the mine shaft in the same manner to ensure that the mine shaft is firmly supported.
