[0002] Mine repair is an important technology in the mining industry, aiming to improve the safety and stability of mines. With the continuous development of the mining industry, mine repair and reinforcement technology has gradually become one of the important means to protect mine safety. This technology not only can effectively prevent the occurrence of mine collapse accidents, but also can prolong the service life of the mine, reduce environmental damage, and improve economic and social benefits. At present, many research institutions and enterprises at home and abroad are constantly exploring and improving the methods and technologies of mine repair and reinforcement to meet the needs of different geological conditions.

[0003] In the existing mine repair and reinforcement methods, common technical means include using concrete grouting, anchor rod support, steel frame support, etc. These methods usually require pouring concrete into the mine wall or rock fissures, or installing anchor rods to enhance the stability of the rock mass, and using steel structural members for physical support. In addition, there are some technical solutions that use hydraulic props, self-expanding materials, etc. for reinforcement. Although these methods can meet the requirements of mine repair to some extent, they generally have problems such as complex construction, high cost, and difficult maintenance.

[0004] However, the above-mentioned traditional mine repair and reinforcement methods have obvious shortcomings in practical application. For example, in complex geological conditions, the traditional method is difficult to achieve precise positioning and uniform stress, resulting in unsatisfactory reinforcement effect; at the same time, due to the complicated operation and long construction period, the project time and cost are increased; in addition, some methods are strongly dependent on equipment, and once the equipment fails, it may affect the progress of the entire project. Therefore, it is urgent to develop a new mine repair and reinforcement structure that can ensure safety while simplifying the construction process, reducing the overall cost, and improving the work efficiency.

[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0025] Embodiment one

[0026] In combination with the drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application. Figures 1-6 As shown in the drawings, the mine repair and reinforcement structure provided by the embodiments of the present application comprises a supporting mechanism 1, an adjusting mechanism 2 is mounted on the surface of the supporting mechanism 1, and a mounting mechanism 3 is mounted on the surface of the supporting mechanism 1 close to the adjusting mechanism 2. The design of this structure makes the mine repair and reinforcement more flexible and efficient, and can adapt to the needs under different geological conditions. Specifically, the supporting mechanism 1 comprises four hollow tubes 101 arranged in a rectangular array, and the four hollow tubes 101 can be made of metal materials such as stainless steel or aluminum alloy, which have high strength and corrosion resistance. The lower surface of each hollow tube 101 is mounted with a moving wheel 102, and the moving wheel 102 can be made of rubber material to increase the friction force, so that the whole structure can move smoothly on rough ground. The opposite sides of every two hollow tubes 101 are jointly fixedly connected with a bearing plate 103, and the bearing plate 103 can be made of high-strength steel plate to ensure the stability and bearing capacity of the structure.

[0027] The upper surface of the bearing plate 103 is fixedly connected with a bidirectional motor 104. The power of the bidirectional motor 104 can be selected according to the actual working condition to ensure sufficient driving force. The two output ends of the bidirectional motor 104 are fixedly connected with rotating rods 105 which are rotatably connected with the hollow pipe 101 through bearing seats. The surface of each rotating rod 105 is fixedly connected with a push plate 106 which is in close contact with the fixed plate 310. The push plate 106 is driven by the bidirectional motor 104 to move the fixed plate 310 up and down, thereby adjusting the height of the mounting mechanism 3. The adjusting mechanism 2 includes a plurality of mounting plates 201 which are fixedly connected to one side of the upper surface of the fixed plate 310. The opposite sides of four mounting plates 201 are rotatably connected with two corresponding rotating rods 202 through bearing seats. The surface of the rotating rod 202 is fixedly connected with a protrusion 203 which is in close contact with the arc-shaped abutting plate 303. The rotating rods 202 can be made of alloy steel to improve durability and wear resistance. The protrusion 203 can be designed in a cylindrical shape or other suitable shape to better fit the arc-shaped abutting plate 303. In addition, the adjusting mechanism 2 also includes two linkage rods 204 which are rotatably connected to the opposite sides of the other four mounting plates 201. The two linkage rods 204 are drivingly connected with the corresponding rotating rods 202 through belts, forming a linkage system. The surface of the linkage rod 204 is fixedly connected with a linkage gear 205, and the two linkage gears 205 are meshed, which can ensure that each rotating rod 202 moves synchronously and avoid structural damage caused by uneven force on a single point. To further improve the stability of the system, anti-loose nuts can be added to both ends of the linkage rod 204 to prevent loosening after long-term use. The mounting mechanism 3 includes two arc-shaped plates 301 which are mounted on the surface of the adjusting mechanism 2. The opposite sides of the two arc-shaped plates 301 are rotatably connected with rotating plates 302 through pin shafts. The surfaces of the four rotating plates 302 are rotatably connected with the arc-shaped abutting plate 303 through pin shafts. The arc-shaped plates 301 and the rotating plates 302 can be made of high-strength plastic or lightweight alloy material, which not only ensures the strength of the structure but also reduces the weight. The surface of the arc-shaped abutting plate 303 is attached with an air bag 304. The inner arc surface of the air bag 304 is fixedly connected with a communication tube 305 which is in communication with the air bag 304. One end of the communication tube 305 is fixedly connected with a mounting tube 306 which is in communication with the communication tube 305. The inside of the mounting tube 306 is fixedly connected with a pressure sensor 307. The air bag 304 can deform when subjected to external force, thereby tightly fitting the rock wall and improving the reinforcement effect. The pressure sensor 307 is used to monitor the pressure change in the air bag 304 to ensure that the contact pressure remains stable within a certain range and to avoid failure caused by overpressure or underpressure. The surface of the arc-shaped plate 301 is provided with mounting grooves 308, and a plurality of communication tubes 305 are slidingly connected in the corresponding mounting grooves 308. This design prevents the communication tubes 305 from winding or falling off during the inflation and deflation of the air bag 304, thereby improving the reliability of the system.The mounting groove 308 can be designed as a T-shaped groove to facilitate the mounting and dismounting of the communication pipe 305.

[0028] Furthermore, the mounting mechanism 3 also includes two sliding plates 309 fixedly connected to the lower surfaces of the two arc-shaped plates 301, the lower surfaces of the sliding plates 309 are slidingly connected with fixed plates 310, the opposite sides of the two fixed plates 310 are slidingly connected with a connecting plate 311, and recesses corresponding to the sliding plates 309 are formed in the upper surfaces of the two fixed plates 310. The sliding connection between the sliding plates 309 and the fixed plates 310 can adopt a ball guide rail to reduce friction resistance and improve movement accuracy. The connecting plate 311 serves to connect the two fixed plates 310 together to form a whole and enhance the rigidity of the structure. The upper surfaces of the fixed plates 310 are fixedly connected with two symmetrical arc-shaped rods 4, and the four arc-shaped rods 4 are respectively fitted with the corresponding mounting pipes 306 to serve as guides and supports. The two edges of one side of the fixed plate 310 are fixedly connected with connecting rods 5, and the upper surfaces of the connecting rods 5 are provided with communication grooves corresponding to the recesses. The connecting rods 5 not only can strengthen the structural strength of the fixed plate 310, but also serve as sliding components inside the hollow pipe 101 to realize the function of height adjustment. In summary, the implementation principle of the embodiment is that through the cooperative work of the supporting mechanism 1 and the adjusting mechanism 2, the accurate adjustment of the height and angle of the mounting mechanism 3 is realized, so that the air bag 304 can closely fit the mine wall to achieve the ideal reinforcement effect. At the same time, the pressure sensor 307 in the air bag 304 monitors the pressure change in real time to ensure the safety and effectiveness of the reinforcement process. This design not only simplifies the construction process, reduces the comprehensive cost, but also improves the operation efficiency, is suitable for various complex geological conditions, and significantly improves the technical level of mine repair and reinforcement.This design not only enhances the safety of the structure, but also improves the construction efficiency, and is suitable for a wider range of mine repair scenarios, further enhancing the application value of mine repair and reinforcement technology. Embodiment Three The difference between this embodiment and the above embodiments is that, on the basis of the adjusting mechanism 2, an intelligent control system is introduced to realize dynamic management of the pressure of the air bag 304. Specifically, the drive motor 206 and the pressure sensor 307 in the adjusting mechanism 2 are connected to a central controller. The central controller is a small computer based on an embedded computing platform, equipped with a data acquisition module, a communication interface and a control algorithm. The data acquisition module is responsible for collecting the pressure value from the pressure sensor 307 and transmitting it to the central controller for processing. The communication interface can be wireless or wired, facilitating remote monitoring and debugging. The control algorithm adjusts the working parameters of the drive motor 206 in real time to maintain the pressure in the air bag 304 within a constant range according to the preset target pressure value through the PID control strategy. In addition, the central controller can also integrate a temperature sensor to monitor the change of environmental temperature. This is because the gas pressure in the air bag 304 will change with temperature fluctuations, affecting the reinforcement effect. By monitoring the temperature in real time, the central controller can automatically compensate for the pressure deviation caused by temperature changes, ensuring that the air bag 304 is always in the best working condition. In summary, the implementation principle of this embodiment is to realize dynamic management and precise control of the pressure of the air bag 304 by introducing an intelligent control system, ensuring the continuous stability and reliability of the mine repair and reinforcement process. This design not only improves the reinforcement effect, but also reduces the influence of human factors, and is suitable for large-scale and continuous mine repair engineering, further improving the intelligent level of mine repair and reinforcement technology. Embodiment Four The difference between this embodiment and the above embodiments is that, on the basis of the mounting mechanism 3, a self-cleaning function is added to prolong the service life of the equipment and improve the maintenance convenience. Specifically, a micro-sprayer is arranged between the arc-shaped plate 301 and the rotating plate 302 in the mounting mechanism 3. The micro-sprayer can be a small high-pressure water gun or a compressed air nozzle, connected to an external water source or air source through a pipeline. When cleaning is needed, the micro-sprayer is turned on, and water or air flows along the surface of the arc-shaped plate 301 and the rotating plate 302, removing dust and impurities and keeping the surface of the equipment clean and tidy. The nozzle of the micro-sprayer can be designed to be adjustable in angle to cover a larger cleaning area. In addition, the outer layer of the air bag 304 can be made of a nano-coating material with self-cleaning properties. This coating material has hydrophobic and oleophobic properties, which can effectively prevent dirt from adhering to its surface, and even if exposed to harsh environments for a long time, it is not easy to get dirty. Regularly turning on the micro-sprayer for cleaning can further enhance this effect and prolong the service life of the air bag 304.In summary, the implementation principle of the embodiment is that by adding the self-cleaning function, the problem of easy dust accumulation and pollution of the mine repair and reinforcement equipment in harsh environments is solved, the service life of the equipment is prolonged, the maintenance frequency is reduced, and the work efficiency is improved. This design not only improves the operation environment of the equipment, but also helps to improve the reliability and sustainability of the overall system, and is especially suitable for long-term use in mine repair projects.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
