Description

Technical Field

[0001] This utility model relates to the field of blasting safety protection technology, specifically a mine entrance safety protection isolation frame for non-metallic mine blasting. Background Technology

[0002] Blasting is a commonly used and critical process in non-metallic mineral mining operations. It uses energy release to crush and strip the ore, creating conditions for subsequent mining and transportation. However, blasting involves many safety hazards, such as flying debris, shock wave propagation, and noise pollution. These factors can not only cause direct harm to equipment and personnel in the work area, but also affect the surrounding environment and non-working personnel. Therefore, strict safety protection measures must be taken.

[0003] Existing mine entrance protection facilities are mostly fixed structures, which are insufficient to effectively cope with the horizontal shock waves generated by blasting. Frontal impacts can easily cause structural damage and pose safety hazards. At the same time, they are not capable of intercepting flying debris during blasting, which can easily fly out of the mine entrance area and cause harm, failing to meet safety protection requirements. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

The existing mine protection facilities are mostly fixed structures, which are difficult to effectively cope with the horizontal shock waves generated by blasting. Frontal impacts can easily cause structural damage and pose safety hazards. At the same time, they are not capable of intercepting the flying debris during blasting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection isolation frame for non-metallic mine blasting, comprising a base plate and side frames. An impact plate is rotatably connected to the top surface of the base plate via a hinge. Limiting grooves are provided on both the left and right sides of the base plate. Limiting blocks are fixedly connected to the lower end of the side walls of the side frames. The limiting blocks are laterally inserted into the inner side of the limiting grooves. A telescopic rod is telescopically and slidably connected to the top of the side frames. An intercepting net is provided between the left and right side frames, and the intercepting net is located above the impact plate.

[0006] In this technical solution, an inclined impact plate is installed on the surface of the base plate, which can effectively block and guide the shock wave generated by blasting upwards, greatly reducing the horizontal impact force. At the same time, in conjunction with the interception net between the side frames, the flying debris can be intercepted, preventing the debris from flying directly out of the mine area, and significantly improving the safety protection level of blasting operations.

[0007] Preferably, the top of the impact plate and the side walls of the left and right side frames are provided with several hooks, and the lower surface of the top of the telescopic rod is also provided with hooks. The interception net is deployed between the left and right side frames through the hooks.

[0008] Preferably, the surface of the base plate and the bottom surface of the side frame are both perforated with pins, and the surface of the limiting block is threaded with fixing bolts.

[0009] Preferably, a storage groove is provided at the center of the top of the base plate, and a support column is rotatably connected between the inner sidewalls of the storage groove. A stop block is fixedly connected to the surface of the impact plate facing the support column.

[0010] Preferably, the base plate has an adjustment groove inside, and a gear is rotatably connected to the bottom surface of the adjustment groove. The gear meshes with the tooth groove provided on the side wall of the connecting rod. The connecting rod is slidably connected in the adjustment groove laterally, and one end of the connecting rod passes through the side wall of the adjustment groove and is located on the outside of the base plate.

[0011] Preferably, a rotating block is fixedly connected to the top of the gear, and the rotating block is located on the top surface of the base plate. A connecting groove is provided on the side wall of the base plate corresponding to the horizontal position of the connecting rod. The connecting groove and the connecting rod are respectively located on the left and right sides of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an inclined impact plate on the surface of the base plate, can effectively block and guide the shock wave generated by blasting upwards, greatly reducing the horizontal impact force. At the same time, in conjunction with the interception net between the side frames, it can intercept the flying debris, preventing the debris from flying directly out of the mine entrance area, and significantly improving the safety protection level of blasting operations.

[0014] 2. This utility model enables the rapid splicing of multiple base plates through the adjustment grooves and connecting grooves on both sides of the base plate.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0022] A safety protection isolation frame for non-metallic mine blasting, see [reference] Figures 1 to 4 The device includes a base plate 1 and side frames 5. An impact plate 2 is rotatably connected to the top surface of the base plate 1 via a hinge. A storage groove 102 is located at the center of the top of the base plate 1. A support column 3 is rotatably connected between the inner walls of the storage groove 102. The support column 3 is stored within the storage groove 102, occupying no extra space when not in use, facilitating the overall storage and transportation of the device. A stop block 201 is fixedly connected to the surface of the impact plate 2 facing the support column 3. The impact plate 2 can rotate around the hinge, thus unfolding during use. When the impact plate 2 rotates to a preset angle, the support column 3 is rotated out of the storage groove 102, causing its top end to abut against the stop block 201 on the inner side of the impact plate 2. The rigid contact between the support column 3 and the stop block 201 fixes the tilted posture of the impact plate 2. The tilted surface guides the horizontal shock wave upwards, significantly reducing the frontal impact force on the isolation frame and solving the problem of existing fixed structures being easily damaged by shock waves. An interception net 7 is provided between the left and right side frames 5 to block... The intercepting net 7 is located above the impact plate 2. Several hooks 8 are provided on the top of the impact plate 2 and on the side walls of the left and right side frames 5. Hooks 8 are also provided on the lower surface of the top of the telescopic rod 6. The intercepting net 7 unfolds between the left and right side frames 5 through the hooks 8. The edge of the intercepting net 7 has a pre-set hanging ring. The intercepting net 7 unfolds between the left and right side frames 5 through the detachable connection between the hanging ring and the hook 8, covering the area above the impact plate 2 and intercepting the flying debris, preventing the debris from flying directly out of the mine opening area, which significantly improves the safety protection level of blasting operations. The top of the side frame 5 is telescopically and slidably connected to the telescopic rod 6. The telescopic rod 6 can be adjusted in height. Several screw holes are provided on its side wall. After the height is adjusted, it is fixed with bolts to ensure stability. The setting of the telescopic rod 6 can flexibly adapt to different sizes of mine openings, ensuring that the coverage of the intercepting net 7 is adapted to the size of the mine opening, which greatly enhances the practicality and adaptability of the device in diverse mining scenarios.

[0023] It should be noted that the interception net 7 can be quickly installed and removed via hook 8, making it easy to replace the interception net 7 with different strengths according to the blasting scenario, such as high-density steel wire mesh, wear-resistant nylon mesh, etc., so as to adapt to the differences in the intensity of flying debris.

[0024] Specifically, an adjustment groove 4 is provided inside the base plate 1. A gear 401 is rotatably connected to the bottom surface of the adjustment groove 4. The gear 401 meshes with the tooth groove provided on the side wall of the connecting rod 402. The connecting rod 402 slides laterally in the adjustment groove 4, and one end of the connecting rod 402 passes through the side wall of the adjustment groove 4 and is located on the outside of the base plate 1. Rotating the rotating block 403 drives the gear 401 to rotate, and the gear 401 meshes with the tooth groove of the connecting rod 402, driving the connecting rod 402 to slide laterally along the adjustment groove 4, thereby adjusting the extension length of the connecting rod 402. Another set of connecting grooves 404 on the side wall of the base plate 1 corresponds to the position of the connecting rod 402. When splicing, the connecting rod 402 is inserted into the connecting groove 404 of the adjacent base plate 1, thereby completing the splicing. Several base plates 1 can be spliced ​​according to the mine opening size, solving the problem of poor adaptability of existing fixed-size devices.

[0025] Furthermore, a rotating block 403 is fixedly connected to the top of the gear 401, and the rotating block 403 is located on the top surface of the base plate 1. A connecting groove 404 is provided on the side wall of the base plate 1 corresponding to the horizontal position of the connecting rod 402. The connecting groove 404 and the connecting rod 402 are located on the left and right sides of the base plate 1, respectively. The rotating block 403 is easy to operate and can complete the extension and retraction adjustment of the connecting rod 402 without professional tools, reducing the installation difficulty. The cooperation between the connecting groove 404 and the connecting rod 402 ensures that the base plate 1 is flat after splicing, improving the overall stability of the base plate 1.

[0026] It is worth noting that, such as Figure 2 and Figure 4 As shown, limit grooves 103 are provided on both the left and right sides of the base plate 1. Limit blocks 501 are fixedly connected to the lower end of the side wall of the side frame 5. The limit blocks 501 are inserted laterally into the inner side of the limit grooves 103. The surface of the limit blocks 501 is threaded with fixing bolts 502. Before the limit blocks 501 are inserted, the fixing bolts 502 are removed. After the limit blocks 501 are inserted, the fixing bolts 502 are screwed in from the holes reserved on the surface of the base plate 1, thereby restricting the limit blocks 501 in the limit grooves 103 and ensuring the stability of the side frame 5. The surface of the base plate 1 and the bottom surface of the side frame 5 are both penetrated by pins 101. The pins 101 can be hammered into the ground, and the overall position of the base plate 1 and the side frame 5 is fixed by the friction between the pins 101 and the ground.

[0027] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
