Technical Field

[0001] This utility model relates to the field of support equipment technology, and in particular to a coal mine tunneling support equipment. Background Technology

[0002] With the increasing demand for coal, the mining depth continues to increase, which worsens the geological environment. As the ground stress increases and the ground temperature continues to rise, accidents frequently occur during the project. Currently, in my country's mine accidents, the number of deaths caused by roof falls accounts for more than 40%. With the gradual improvement of the mechanization level in coal mines, the requirements for mining technology in mines are getting higher and higher, and the scope of use of underground mining machinery and equipment is also getting wider and wider.

[0003] For coal mining faces with deep coal seams, large mechanical equipment can be used to support the ends. However, for coal mining faces with thinner coal seams, the vertical height of the coal seam is relatively low, so large mechanical equipment cannot be used for support.

[0004] Therefore, it is necessary to provide a new coal mine tunneling support equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem of not being able to use large mechanical equipment for support in coal mining faces with thin coal seams and low spatial height, this utility model provides a coal mine tunneling support device.

[0008] Preferably, the bottom of the extension portion is detachably mounted with a connecting plate that is fixedly connected to the threaded rod via a fixing bolt. The bottom of the connecting plate is mounted with a triangular plate that is connected to the threaded rod. The triangular plate is used to stabilize the angle of the threaded rod relative to the connecting plate.

[0009] Preferably, a moving wheel for assisting the overall movement of the support equipment is rotatably mounted on one side of the support block, and an extension plate is fixed on the other side of the support block. A fixing cone that can be inserted into the ground to stabilize the equipment is movably mounted on the extension plate, and a limiting block located above the extension plate is installed on the top of the fixing cone.

[0010] Preferably, the threaded cylinder is fitted with an anti-slip sleeve to provide an operating grip point and increase grip friction. The connecting plate, threaded rod, threaded cylinder and support block are all arranged in groups and located on both sides of the support frame.

[0011] Preferably, the support rod includes two rotating shafts respectively rotatably mounted on the two support plates, two connecting cylinders fixed on the side of the two rotating shafts close to each other, two threaded blocks threadedly installed in the two connecting cylinders, and an extension shaft fixed between the two threaded blocks.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-4 The coal mine tunneling support equipment includes: two support plates 1, each support plate being arc-shaped with horizontal extensions at both ends; multiple support rods 2 installed between the two support plates 1 for supporting the coal mine excavation space; a support frame 3 fixed inside the support plates 1 to prevent deformation of the support plates 1; a support structure detachably installed at the bottom of the extensions to support the support plates 1; and an isolation pad 10 covering the top of the multiple support rods 2 to isolate mine roadway debris. By setting two support plates 1, the initial support effect of the coal mine excavation space is achieved. By installing multiple support rods 2 between the two support plates 1, the excavation space is stabilized, enhancing the support strength. By fixing the support frame 3 inside the support plates 1, deformation of the support plates 1 is effectively prevented, extending their service life. The detachable support structure allows the equipment to flexibly adjust the support height according to different geological conditions, improving applicability. The isolation pad 10 covering the top of the support rods 2 isolates mine roadway debris, preventing debris from falling and affecting operational safety, and providing a safe and reliable working environment for underground workers and equipment.

[0023] The support structure includes a threaded rod 6 detachably installed at the bottom of the extension section, a threaded cylinder 7 threaded around the threaded rod 6, and a support block 8 rotatably installed at the bottom of the threaded cylinder 7 to support the entire support equipment. By setting the threaded rod 6 detachably installed at the bottom of the support plate 1, the support structure can be flexibly installed and disassembled according to actual needs, improving the assembly efficiency and flexibility of the equipment. The threaded cylinder 7 threaded around the threaded rod 6 facilitates the adjustment of the support height, allowing the support equipment to adapt to different undulating underground ground surfaces and enhancing support stability. The support block 8 rotatably installed at the bottom of the threaded cylinder 7 makes the rotation adjustment of the threaded cylinder 7 easier and reduces the difficulty of operation.

[0024] The bottom of the extension section is detachably mounted with a connecting plate 5 fixedly connected to the threaded rod 6 via fixing bolts 4. A triangular plate 11 connected to the threaded rod 6 is installed at the bottom of the connecting plate 5. The triangular plate 11 is used to stabilize the angle of the threaded rod 6 relative to the connecting plate 5. By setting the fixing bolts 4, the support plate 1 and the connecting plate 5 can be detachably connected, which facilitates the installation, disassembly and replacement of parts, and improves the maintenance efficiency of the equipment. The fixed connection between the connecting plate 5 and the threaded rod 6 plays a role in the stable transmission of support force, ensuring that the overall support structure is subjected to uniform force. The triangular plate 11 is installed at the bottom of the connecting plate 5 and connected to the threaded rod 6, which plays a role in stabilizing the angle of the threaded rod 6 relative to the connecting plate 5, making it difficult for the threaded rod 6 to deviate when adjusted or subjected to force, thus ensuring the verticality and stability of the support structure.

[0025] One side of the support block 8 is rotatably equipped with a moving wheel 16 for assisting the overall movement of the support equipment. The other side of the support block 8 is fixed with an extension plate 17. A fixing cone 18 that can be inserted into the ground to stabilize the equipment is movably installed on the extension plate 17. A limiting block located above the extension plate is installed on the top of the fixing cone 18. By rotatably installing the moving wheel 16 on the support block 8, the overall movement of the support equipment is facilitated. When the equipment position needs to be adjusted, there is no need to spend a lot of manpower to move it, which improves the work efficiency. By fixing the extension plate 17 on the support block 8 and movably installing the fixing cone 18 that can be inserted into the ground on the extension plate 17, the stability is enhanced after the equipment is positioned. The insertion of the fixing cone 18 into the ground can effectively prevent the equipment from sliding or shifting, ensuring the safety of the support. The limiting block installed on the top of the fixing cone 18 makes the insertion depth of the fixing cone 18 into the ground controllable, avoiding the problem of it being difficult to pull out if inserted too deeply.

[0026] The threaded cylinder 7 is fitted with an anti-slip sleeve 9 to provide a gripping point and increase grip friction. The connecting plate 5, threaded rod 6, threaded cylinder 7, and support block 8 are all grouped and located on both sides of the support frame 3. By fitting the anti-slip sleeve 9 over the threaded cylinder 7, a clear gripping point is provided for the operator, and the friction during gripping is effectively increased. This makes it easier to adjust the support height by adjusting the threaded cylinder 7, and reduces the likelihood of slippage. The support frame includes two inclined frames arranged in a V-shape and a horizontal frame connecting the two inclined frames. By grouping the connecting plate 5, threaded rod 6, threaded cylinder 7, and support block 8 and placing them on both sides of the support frame 3, the support force is evenly distributed, enhancing the overall stability and load-bearing capacity of the equipment.

[0027] The support rod 2 includes two rotating shafts 12 respectively rotatably mounted on the two support plates 1, two connecting cylinders 13 fixed on one side of the two rotating shafts 12 close to each other, two threaded blocks 14 threadedly mounted inside the two connecting cylinders 13, and an extension shaft 15 fixed between the two threaded blocks 14. By setting the rotating shafts 12 respectively rotatably mounted on the two support plates 1, the effect of facilitating the rotation of the connecting cylinders 13 is achieved. By setting the threaded blocks 14 threadedly mounted inside the connecting cylinders 13, and cooperating with the extension shaft 15 fixed between the two threaded blocks 14, the extension shaft 15 is detachable, increasing the flexibility of the equipment. When the equipment is idle, each component can be disassembled and stored.

[0028] The isolation pad 10 has metal wires inside to increase its strength, and a plastic protective film for waterproofing and dustproofing is outside the isolation pad 10. By setting metal wires inside the isolation pad 10, the strength of the isolation pad 10 is enhanced, making it less prone to damage when subjected to the pressure and friction of mine slag, thus extending the service life of the isolation pad 10. It can more effectively and permanently isolate mine slag, ensuring a safe working environment. The plastic protective film outside the isolation pad 10 provides good waterproofing and dustproofing, preventing moisture and dust from penetrating the interior of the isolation pad 10 and avoiding performance degradation due to moisture or dust accumulation, further improving the durability of the isolation pad 10.

[0029] The working principle of the coal mine tunneling support equipment provided by this utility model is as follows:

[0030] In use, place the two support plates 1 in a suitable position in the coal mine mining space, and detachably install the connecting plate 5 at the bottom of the support plate 1 by fixing bolts 4. Thread the threaded cylinder 7 onto the threaded rod 6. Depending on the undulation of the underground ground, the operator holds the anti-slip cylinder 9 and rotates the threaded cylinder 7 to adjust the support height so that the support block 8 contacts the ground. If the equipment needs to be moved, use the movable wheels 16 installed on the support block 8 to move it. After moving to a suitable position, insert the fixed cone 18 movably installed on the extension plate 17 into the ground. Control the insertion depth by the limit block. Finally, install the support rod 2 between the two support plates 1 and lay the isolation pad 10.
