Description

Technical Field

[0001] This utility model relates to the field of rock mass support technology, specifically a support and reinforcement structure for mining roof pillars. Background Technology

[0002] The essence of underground mining is the artificial excavation of rock mass to form working space and mining area. This process inevitably breaks the original stress balance of the rock mass. The weight of the overlying rock layer and the hanging wall ore body above the mining area will be transferred to the "residual rock mass" around the mining area. Among them, the top pillar, as the load-bearing ridge of the top of the mining area, becomes the core carrier of stress concentration.

[0003] A search revealed Chinese patent publication (CN212837896U), which includes a workbench with a support structure mounted on its upper wall. An adjustment structure is fitted onto the upper surface of the support structure. A first transmission structure and a second transmission structure are mounted on the upper wall of the workbench. A rock mass protection structure is mounted on the upper wall of the adjustment structure. The support structure includes a stabilizing frame, two hydraulic cylinders, and two hydraulic rods. The stabilizing frame is mounted on the upper wall of the workbench, the two hydraulic cylinders are respectively mounted on the upper wall of the workbench, and the two hydraulic rods are respectively mounted on the inner walls of the two hydraulic cylinders.

[0004] When the above-mentioned patent is used, it proposes to use two hydraulic rods in the support structure to move up and down along two hydraulic cylinders, which effectively solves the problem that the existing mining roof rock mass support system cannot be adjusted. However, the single hydraulic cylinder structure has poor stability and is prone to tilting and collapse. At the same time, the overall equipment support area is fixed, and when facing a large support surface, multiple support frames need to be installed at the same time.

[0005] To address this, we propose a top pillar support and reinforcement structure for mining areas with multiple supporting structures and adjustable support area. Utility Model Content

[0006] One of the technical problems this application aims to solve is that a single hydraulic cylinder structure has poor stability and is prone to tilting and collapse. At the same time, the overall equipment support area is fixed, and when facing a large support surface, multiple support frames need to be installed simultaneously.

[0007] To solve the above-mentioned technical problems, this application provides a mining top support reinforcement structure, including a base, with two corrugated grooves inside the base, support rods rotatably connected to both the left and right sides of the base, a connecting rod rotatably connected between the two support rods, and limit blocks provided on opposite sides of the two support rods.

[0008] In some embodiments, a main support plate is rotatably connected between the two limiting blocks. A protective plate is provided inside the main support plate. Two air pumps are provided on the rear side of the protective plate. A limiting rod is provided at the bottom end of the protective plate. A secondary support plate is slidably connected to the bottom end of the main support plate. A long groove is opened inside the secondary support plate.

[0009] In some embodiments, an air pump 2 is rotatably connected to the bottom end of the main support plate, a secondary support plate 2 is rotatably connected to the front side of the main support plate, a connecting block is provided at the bottom end of the secondary support plate 2, two support blocks are provided in the middle of the base, and an air pump 3 is provided at the top of each of the two support blocks.

[0010] In some embodiments, the limiting block is slidably engaged with the inner wall of the wave-shaped groove.

[0011] In some embodiments, the two wave-shaped slots are staggered relative to each other, and the two limiting blocks are distributed in an X-shape.

[0012] In some embodiments, the ends of the two air pumps away from the protective plate are both disposed on the inner wall of the secondary support plate, and the secondary support plate is slidably connected between the protective plate and the main support plate.

[0013] In some embodiments, the ends of the two air pumps furthest from the base are both located at the bottom end of the main support plate.

[0014] In some embodiments, the limiting rod is slidably connected to the inner wall of the long groove, and the end of the second air pump away from the main support plate is rotatably connected to the inside of the connecting block.

[0015] This utility model has at least the following beneficial effects: 1. The overall support frame height is determined by adjusting the support rods, and the limit block is then fixed in the corrugated slot. At the same time, the height is adjusted by the air pump to achieve a double fixing method, which effectively increases the overall safety of the top support reinforcement structure in the mining area. It also greatly simplifies the overall installation and fixing operation of the equipment, further saves installation time, and improves the convenience and efficiency of support operations.

[0016] 2. By using air pump one to drive the extension and retraction of secondary support plate one, and air pump two to drive the rotation of secondary support plate two, the structure can be expanded to extend the overall protection function. The protection area can be flexibly adjusted according to the user's actual terrain needs, and secondary support plate two can be adjusted according to the angle of different slopes. This greatly improves the adaptability of the support and reinforcement structure to complex terrain in the mining area, ensuring the comprehensiveness and practicality of the support protection.

[0019] 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. Example 1:

[0020] Please see Figures 1-4 This utility model provides a technical solution: A top support reinforcement structure for a stope includes a base 1. The base 1 serves as the load-bearing foundation of the entire support reinforcement structure, providing stable support for the installation and operation of subsequent components, especially suitable for the load-bearing requirements of pre-controlled deep-hole blasting mining in steeply inclined thin ore veins. The base 1 has two corrugated grooves 2 inside, which provide adjustable locking positions for limiting blocks 5. The corrugated groove structure allows the limiting blocks 5 to be fixed at different heights, thereby adjusting the overall support height in conjunction with support rods 3 to meet the different support height requirements in pre-controlled deep-hole blasting mining of steeply inclined thin ore veins. Support rods 3 are rotatably connected to both sides of the base 1. The support rods 3 can rotate around the base 1, and the rotation adjustment allows for adjustment of the support angle and height of the main support plate 6. This is the core support component for overall structural height adjustment, ensuring the stability of the support structure during pre-controlled deep-hole blasting mining of steeply inclined thin ore veins. A connecting rod 4 is rotatably connected between the two support rods 3, enhancing the linkage and structural integrity between the two support rods 3 and preventing... The force offset of a single support rod 3 enhances the deformation resistance of the support structure. Limiting blocks 5 are installed on opposite sides of both support rods 3. These limiting blocks 5 work in conjunction with the corrugated groove 2, fixing the support angle of the support rod 3 by engaging at different positions within the groove 2, thereby locking the overall support height and ensuring stable support height. The limiting blocks 5 slide against the inner wall of the corrugated groove 2. This sliding engagement allows for easy adjustment of the limiting blocks 5 as needed, and ensures reliable fixation through the groove structure of the corrugated groove 2 after adjustment, preventing slippage under stress and guaranteeing the safety of the support structure. The two corrugated grooves 2 are staggered, allowing the two limiting blocks 5 to operate without interference during adjustment, while forming a more stable support point, improving the overall support stability and adapting to complex mining environments. The two limiting blocks 5 are arranged in an X-shape, forming a cross-support structure that disperses the pressure transmitted by the support rods 3, preventing excessive local stress from causing structural damage and enhancing the overall load-bearing capacity of the support structure. Example 2:

[0021] Please see Figures 1-4 This utility model provides a technical solution: A main support plate 6 is rotatably connected between the two limiting blocks 5. The main support plate 6 serves as the primary load-bearing panel of the support structure, directly bearing the pressure of the mine roof pillar. Its rotatable connection with the limiting blocks 5 allows for angle adjustment in conjunction with the support rod 3, ensuring a tight fit with the roof pillar and effectively transmitting and dispersing the roof pillar pressure. A protective plate 7 is installed inside the main support plate 6. This protective plate 7 enhances the structural strength and impact resistance of the main support plate 6, preventing damage when subjected to roof pillar pressure or mining operation impacts, and extending the service life of the support structure. Two air pumps 8 are installed on the rear side of the main support plate 7. The air pumps 8 provide power for the telescopic movement of the auxiliary support plate 10. The telescopic movement of the air pumps 8 drives the auxiliary support plate 10 to slide, thereby expanding the protection area and meeting the protection needs of different mining areas. A limit rod 9 is installed at the bottom of the protective plate 7. The limit rod 9 cooperates with the long groove 11 of the auxiliary support plate 10 to limit the sliding direction and sliding range of the auxiliary support plate 10, preventing the auxiliary support plate 10 from deviating or detaching from the main support plate 6 during telescopic movement, and ensuring the stability of the telescopic movement. The auxiliary support plate 10 is slidably connected to the bottom of the main support plate 6. 0. The secondary support plate 10 can slide along the main support plate 6, thereby expanding the protective area and compensating for the insufficient protective area of ​​the main support plate 6. The protective range can be flexibly adjusted according to the size of the working area. The secondary support plate 10 has an internal long groove 11, which provides sliding space for the limiting rod 9. At the same time, the sliding trajectory of the limiting rod 9 in the long groove 11 limits the sliding stroke of the secondary support plate 10, ensuring the controllability of the extension and retraction movement of the secondary support plate 10 and avoiding structural failure due to excessive sliding. The ends of the two air pumps 8 away from the protective plate 7 are both located on the secondary support plate 10. On the inner wall, the air pump 8 is connected to the protective plate 7 and the auxiliary support plate 10 at both ends, forming a stable power transmission structure. The extension and retraction of the air pump 8 directly drives the auxiliary support plate 10 to slide, which is efficient and stable and ensures the smooth extension and retraction of the auxiliary support plate 10. The auxiliary support plate 10 is slidably connected between the protective plate 7 and the main support plate 6. The gap formed between the protective plate 7 and the main support plate 6 provides a sliding track for the auxiliary support plate 10 and at the same time plays a role in limiting the upper and lower movement of the auxiliary support plate 10, preventing the auxiliary support plate 10 from shifting up and down during the sliding process and ensuring the flatness of the protective structure.

[0022] A second air pump 12 is rotatably connected to the bottom end of the main support plate 6. The second air pump 12 provides power for the rotation of the second auxiliary support plate 13. The extension and retraction of the second air pump 12 drives the second auxiliary support plate 13 to rotate around the main support plate 6, thereby adjusting the tilt angle of the second auxiliary support plate 13 to adapt to different sloping mining terrains. The second auxiliary support plate 13 is rotatably connected to the front side of the main support plate 6. The second auxiliary support plate 13 can rotate around the main support plate 6, and the angle adjustment can achieve support for different sloping areas, further expanding the protection area, adapting to complex sloping terrains, and improving the comprehensiveness of support. A connecting block 14 is provided at the bottom end of the second auxiliary support plate 13. The connecting block 14 is used for... The secondary support plate 13 connects to the air pump 12, providing a stable power point for the air pump 12 and ensuring that the power of the air pump 12 is effectively transmitted to the secondary support plate 13, thus ensuring the accuracy of the rotation angle adjustment of the secondary support plate 13. Two support blocks 15 are provided in the middle of the base 1, fixed in the middle of the base 1, for installing the air pump 16, providing a stable mounting base for the air pump 16, ensuring that the air pump 16 will not shift during operation, and ensuring the stability of the air pump 16's support for the main support plate 6. The top of each of the two support blocks 15 is equipped with the air pump 16, which cooperates with the support rod 3 and the limiting block 5. The system employs a double-fixation mechanism. The height of the main support plate 6 is further adjusted and locked via the extension and retraction of the air pump 316, enhancing the overall structural stability and preventing safety hazards caused by the failure of a single fixing method, thus improving the safety of the support structure. The ends of both air pumps 316 furthest from the base 1 are positioned at the bottom of the main support plate 6. Each end of the air pump 316 is connected to the support block 15 and the main support plate 6, forming direct support for the main support plate 6. The supporting force of the air pumps 316 disperses the pressure transmitted from the main support plate 6 to the support rod 3, improving the overall structural load-bearing capacity and ensuring the support effect. The limiting rod 9 is slidably connected to the inner wall of the long groove 11. The sliding connection structure between 9 and the long groove 11 not only limits the position of the auxiliary support plate 10, but also does not affect the normal extension and retraction of the auxiliary support plate 10. This ensures that the auxiliary support plate 10 can slide flexibly without deviating from the track when adjusting the protective area, thus ensuring the reliability of the structure's operation. The end of the air pump 12 away from the main support plate 6 is rotatably connected to the inside of the connecting block 14. This rotatable connection allows the air pump 12 to adapt to angle changes when driving the auxiliary support plate 13 to rotate, avoiding damage to the air pump 12 due to a fixed angle. At the same time, it ensures continuous and stable power transmission and guarantees the smoothness of the tilt angle adjustment of the auxiliary support plate 13.

[0023] Based on the above embodiments, the following is the complete working principle of the above embodiments: When support is required, the height of the overall support frame is determined by adjusting the support rod 3. After adjustment, it is only necessary to lock the two limit blocks 5 into the wave groove 2 to complete the fixation. With the help of the air pump 3 16 to adjust the height, double fixation is completed, which increases the overall safety and facilitates the overall installation and fixation of the equipment, saving installation time. The two air pumps 1 8 drive the auxiliary support plate 1 10 to move in extension and retraction, and the air pump 2 12 drives the auxiliary support plate 2 13 to rotate, which can expand the overall protective equipment. The protective area can be adjusted according to the user's terrain requirements. At the same time, the auxiliary support plate 2 13 can be adjusted according to the angle of different slopes.
