Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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 protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a fixed-point grouting and borehole protection device for mine area treatment. The device mainly consists of a first fixing plate 1 and a second fixing plate 2, which are joined together to form a through hole 3. The through hole 3 is designed to allow the grouting anchor rod to pass smoothly through laterally. Rectangular through slots 4 are horizontally formed on both the first fixing plate 1 and the second fixing plate 2. These rectangular through slots 4 have internal protective structures to protect the borehole from damage. Furthermore, disassembly and stabilization components are connected between the first fixing plate 1 and the second fixing plate 2 to ensure the stability and ease of disassembly and assembly of the device. The protective structure specifically includes a protective baffle 10 inserted into the inner wall of the rectangular through slot 4. The upper surface of the protective baffle 10 is designed with a slope 11. When the grouting anchor rod passes through the through hole 3, it will abut against the slope 11, causing the protective baffle 10 to move and provide protection. Simultaneously, a reset mechanism is connected between the rectangular through slot 4 and the protective baffle 10 to reset the protective baffle 10 after the grouting anchor rod passes through.

[0024] like Figure 1-4 As shown, the reset mechanism includes a strip-shaped groove 5 formed on the inner wall of a rectangular through slot 4. A horizontal fixing rod 7 is installed on the end wall of the strip-shaped groove 5, and a spring 8 is sleeved around the horizontal fixing rod 7. A sliding sleeve block 9 is also slidably sleeved around the horizontal fixing rod 7, and the opposing surfaces of the two sliding sleeve blocks 9 are fixedly connected to the two side surfaces of a protective baffle 10. When the grouting anchor rod abuts against the protective baffle 10, the protective baffle 10 will drive the sliding sleeve block 9 to slide on the horizontal fixing rod 7, compressing the spring 8. After the grouting anchor rod passes through, the elastic force of the spring 8 will reset the protective baffle 10; the reset mechanism can effectively reset the protective baffle 10 after the grouting anchor rod passes through.

[0025] like Figure 1-4 As shown, the disassembly and assembly components include connecting blocks 12 that are fixedly connected to the sides of fixing plate 1 and fixing plate 2. The surface of the connecting block 12 on the side of fixing plate 1 is threaded with screws 13, while the surface of the connecting block 12 on the side of fixing plate 2 is fitted with nuts 14. By rotating the screws 13 and nuts 14, fixing plate 1 and fixing plate 2 can be easily disassembled and assembled.

[0026] like Figure 1-4 As shown, the stabilizing assembly includes a plug rod 15 fixedly connected to the end of the first fixing plate 1 and a stabilizing insertion hole 16 formed on the surface of the second fixing plate 2 opposite to the end of the first fixing plate 1. The plug rod 15 can be inserted into the inner wall of the stabilizing insertion hole 16, thereby increasing the stability between the first fixing plate 1 and the second fixing plate 2.

[0027] like Figure 1-4 As shown, mounting holes 17 are provided on both the first mounting plate 1 and the second mounting plate 2, and cement nails 18 can be inserted into the inner wall of the mounting holes 17. The cement nails 18 can be used to fix the first mounting plate 1 and the second mounting plate 2 to their respective positions, ensuring that the device will not move during use.

[0028] like Figure 1-4 As shown, the end wall of the strip groove 5 has an insertion hole 6, and the end of the horizontal fixing rod 7 is inserted into the inner wall of the insertion hole 6. The inner diameter of the insertion hole 6 is matched with the outer diameter of the horizontal fixing rod 7 to ensure that the horizontal fixing rod 7 can be stably fixed in the strip groove 5; the horizontal fixing rod 7 can be firmly installed in the strip groove 5, providing stable support for the reset mechanism.

[0029] like Figure 1-4 As shown, one end of screw 13 passes through the connecting block 12 on the side of fixing plate 2, and nut 14 is threaded onto the outer periphery of the threaded section of screw 13. By rotating nut 14, the fastening or loosening between fixing plate 1 and fixing plate 2 can be easily achieved.

[0030] like Figure 1-4As shown, the plug rod 15 is inserted into the inner wall of the stable socket 16, and the inner diameter of the stable socket 16 is matched with the outer diameter of the plug rod 15. This design ensures that the plug rod 15 can be stably inserted into the stable socket 16, providing additional stability for the connection between the fixing plate 1 and the fixing plate 2.

[0031] The working principle of this utility model is as follows: First, the device consists of a fixing plate 1 and a fixing plate 2, which are detachably connected together through a disassembly component. After assembly, a through hole 3 is formed between the fixing plate 1 and the fixing plate 2. The design size of the through hole 3 matches that of the grouting anchor rod, ensuring that the grouting anchor rod can pass through smoothly.

[0032] Rectangular through slots 4 are horizontally formed on both fixing plate 1 and fixing plate 2. These rectangular through slots 4 are equipped with protective structures to protect the borehole from damage when the grouting anchor rod passes through. Specifically, the protective structures include protective baffles 10 inserted into the inner wall of the rectangular through slots 4. The upper surface of the protective baffles 10 is designed with a slope 11. When the grouting anchor rod passes through the through hole 3 and abuts against the slope 11, the protective baffles 10 will move along the direction of the slope 11, thus providing sufficient space for the grouting anchor rod.

[0033] To ensure the protective baffle 10 can reset after the grouting anchor rod passes through, a reset mechanism is connected between the rectangular through groove 4 and the protective baffle 10. The reset mechanism includes a strip-shaped groove 5 formed in the inner wall of the rectangular through groove 4, with a horizontal fixing rod 7 installed on the end wall of the strip-shaped groove 5. A spring 8 is sleeved around the horizontal fixing rod 7, with one end of the spring 8 connected to the end wall of the strip-shaped groove 5 and the other end connected to the protective baffle 10 via a sliding sleeve block 9. When the protective baffle 10 moves, it causes the sliding sleeve block 9 to slide on the horizontal fixing rod 7, compressing the spring 8. After the grouting anchor rod passes through, the elastic force of the spring 8 will reset the sliding sleeve block 9 and the protective baffle 10.

[0034] In addition, to enhance the connection stability between the first fixing plate 1 and the second fixing plate 2, the device is also equipped with a stabilizing component. The stabilizing component includes a plug rod 15 fixedly connected to the end of the first fixing plate 1 and a stabilizing insertion hole 16 opened on the surface of the second fixing plate 2 opposite to the end of the first fixing plate 1. The plug rod 15 can be inserted into the inner wall of the stabilizing insertion hole 16, thereby increasing the connection strength between the first fixing plate 1 and the second fixing plate 2;

[0035] Finally, to facilitate fixing the device in the desired location, mounting holes 17 are provided on both mounting plate 1 and mounting plate 2. By inserting cement nails 18 into these mounting holes 17, the device can be securely fixed around the borehole in the mining area.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
