Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining safety protection equipment, and in particular to a mining safety protection device. Background Technology
[0002] Safety is always paramount in mining operations, especially in open-pit mines or underground tunnels where accidents such as rockfalls and tumbling rocks are frequent. Traditional safety measures often rely on simple barrier structures, such as sandbags, fixed barriers, or simple safety nets. While these devices provide basic protection, they have many limitations in practical applications. For example, sandbag walls lack stability and impact resistance, and are prone to collapse or displacement when struck by falling rocks, leading to protective failure. Fixed barriers, on the other hand, are rigid in structure and difficult to adapt to the flexible needs of different terrains and working conditions. They may also shift due to rockfall impacts and are difficult to quickly reposition after an impact, requiring frequent manual maintenance and repair.
[0003] While some mechanical structures in existing technologies are used in the field of protection, their design and function still have significant shortcomings. For example, some devices use rigidly connected metal frames as the main protective structure. Although they can withstand a certain degree of impact, they rely entirely on the strength of the material to resist external forces and lack effective buffering and energy absorption mechanisms. When subjected to impact, the metal frame is prone to permanent deformation, or the impact may cause the frame to become unstable. Furthermore, damage to the local structure may further reduce the protective performance.
[0004] However, when traditional protective devices are subjected to impacts, if they cannot effectively absorb the impact energy and return to their original position when rocks hit the protective structure, or if they are not securely fixed and cannot withstand the impact of rocks, the protective devices will gradually damage and fail under repeated impacts, and will not be able to continuously ensure the safety of mining operations. This problem makes it difficult for existing protective devices to play an ideal protective role when dealing with frequent rockfalls. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a mining safety protection device, which aims to improve the problem that when a rock-impacted protective structure is used, it cannot effectively absorb impact energy and return to its original position, is not firmly fixed and cannot resist the impact of rock-impacted structures, and the protective device gradually damages and fails under repeated impacts.

[0010] Furthermore, a total of five buffer components are provided, all of which are fixedly connected between the buffer plate and the support plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-5 This utility model provides an embodiment of a mining safety protection device, including a fixing plate 1. The fixing plate 1 has holes inside, which fit against one side of the outer wall of a ground pile 2. This fit provides a stable initial connection structure, ensuring no relative displacement between the fixing plate 1 and the ground pile 2, thus guaranteeing the overall stability of the device. The ground pile 2 is slidably connected to the inner wall of the fixing plate 1. A conical tip 31 is fixedly connected to one side of the outer wall of the ground pile 2. A threaded rod 10 is threadedly connected to the inner wall of the ground pile 2. A hexagonal bolt head 3 is fixedly connected to one end of the threaded rod 10, and a pushing block 11 is fixedly connected to the other end of the threaded rod 10. The threaded connection between the threaded rod 10 and the ground pile 2 allows the pushing block 11 to be adjusted in position by rotating the hexagonal bolt head 3, facilitating subsequent anchoring. To provide force transmission, the ground pile 2 has a groove inside, which fits against one side of the outer wall of the sliding block 13. The sliding block 13 is slidably connected to the inner wall of the ground pile 2, and a fixed block 12 is fixedly connected to one side of the outer wall of the sliding block 13. This allows the sliding block 13 to slide inside the ground pile 2, thereby driving the fixed block 12 to move, achieving anchoring to the surrounding soil and enhancing pull-out resistance. A fixed shaft 15 is fixedly connected to the inner wall of the fixed plate 1, and a support plate 5 is rotatably connected to one side of the outer wall of the fixed shaft 15. A buffer assembly is provided on one side of the outer wall of the support plate 5. A total of five buffer assemblies are provided, all of which are fixedly connected between the buffer plate 4 and the support plate 5. The multiple buffer assemblies are evenly distributed to ensure that the buffer plate 4 can fully and evenly disperse the impact force when subjected to impact, thereby improving the buffering effect.
[0027] The buffer assembly includes a buffer outer tube 28, one side of which is fixedly connected to the outer wall of a support plate 5. A spring 29 is fixedly connected to one side of the outer wall of the buffer outer tube 28, and a telescopic rod 30 is installed inside the spring 29. The spring 29 effectively absorbs impact energy, while the telescopic rod 30 provides guidance and support inside the spring 29 to ensure a smooth buffering process. One side of the telescopic rod 30 is slidably connected to the inner wall of the buffer outer tube 28, and a buffer plate 4 is fixedly connected to one side of the outer wall of the telescopic rod 30. A fixed block 24 is connected, and a rotating shaft 26 is fixedly connected to the inner wall of the fixed block 24. The fixed block 24 provides a fixed support for the rotating shaft 26, allowing the connecting plate 23 to rotate flexibly around the rotating shaft 26. A connecting plate 23 is rotatably connected to one side of the outer wall of the rotating shaft 26. A rotating shaft 1 25 is rotatably connected to the inner wall of the connecting plate 23. A connecting rod 21 is fixedly connected to one side of the outer wall of the rotating shaft 1 25. A rotating shaft 3 27 is rotatably connected to the inner wall of the connecting rod 21. A fixed block 3 22 is fixedly connected to one side of the outer wall of the rotating shaft 3 27.
[0028] Reference Figures 1-5 A fixing block 20 is fixedly connected to one side of the outer wall of the support plate 5. A fixing shaft 3 19 is fixedly connected to one side of the outer wall of the fixing block 20. The fixing shaft 3 19 provides rotational support for the support rod 6, allowing the support rod 6 to adjust its angle around it. The support rod 6 is rotatably connected to one side of the outer wall of the fixing shaft 3 19. Both the support rod 6 and the support rod 2 7 have holes inside, which fit against one side of the outer wall of the pin rod 16. The pin rod 16 is slidably connected to the inner wall of the support rod 6. The sliding connection of the pin rod 16 allows for quick locking or releasing of the support rod 2 7, facilitating folding and unfolding. A fixing shaft 2 17 is fixedly connected to the inner wall of the support rod 6. A support rod 7 is rotatably connected to one side of the wall. The angle of the support rod 7 can be adjusted on the fixed shaft 17 through rotational connection. The support plate 5 has a groove for fixing the fixed rod 18. One side of the outer wall of the fixed rod 18 fits against one side of the outer wall of the support rod 7. A baffle 8 is fixedly connected to one side of the outer wall of the support rod 6. The baffle 8 limits the insertion depth of the cone tip 9, protects the support rod 6 from excessive support, and extends its service life. A crossbar 14 is fixedly connected to one side of the outer wall of the support rod 6. A cone tip 9 is fixedly connected to one end of the support rod 6. The cone tip 9 can be quickly inserted into the ground, providing a stable support point for the support rod 6 and enhancing the stability of the device.
[0029] Working principle: During device installation, the cone tip 2.31 is aligned with the predetermined position, and the cone tip 2 and the ground stake 2 are driven into the ground to a predetermined depth using an impact device. Then, by rotating the hexagonal bolt head 3, the threaded rod 10 rotates inside the ground stake 2, causing the pushing block 11 to move downward. The downward-moving pushing block 11 presses against the fixing block 12, causing the sliding block 13 to slide and embed into the surrounding soil, forming anchoring force and pull-out resistance, thus stabilizing the fixing plate 1. When there are rolling stones, pressure is generated by impacting the buffer plate 4, which, under the action of the spring 29, causes the telescopic rod 30 to move inside the buffer outer tube 28. During the extension and retraction, because the fixed block 24 is fixedly connected to the buffer plate 4, the connecting plate 23 rotates between the two fixed blocks 24 with the rotating shaft 26 as the axis. Similarly, one end of the connecting rod 21 rotates between the two connecting rods 21 with the rotating shaft 1 25 as the axis, and the other end rotates between the two fixed blocks 22 with the rotating shaft 3 27 as the axis. Through the diamond bracket and the spring 29, the buffer plate 4 can return to its original position after buffering the rolling stone. At the same time, under the fixation of the support plate 5, the slope angle of the device remains unchanged after buffering.
[0030] Furthermore, when the device is unfolded, the support plate 5 is lifted to a suitable angle under the action of the fixed shaft 15. At this time, the support rod 6 is pulled, and under the action of the fixed shaft 19, the support rod 6 rotates between the two fixed blocks 20. Under the fixed connection of the crossbar 14, the other one rotates in the same way. Then, a suitable angle is selected and the cone tip 9 is inserted into the ground. Under the action of the baffle 8, the insertion depth is limited. At this time, the pin rod 16 is pulled to unlock the support rod 7, so that one end of the support rod 7 rotates under the action of the fixed shaft 17, and the other end is fastened to the fixed rod 18.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
