Description

Technical Field

[0001] This utility model relates to the field of blasting protection technology, specifically to a blasting protection device for metal mines that can be quickly assembled and constructed. Background Technology

[0002] At mine blasting sites, blasting operations are often accompanied by blast waves and a large amount of debris being ejected. Although workers maintain a safe distance from the blasting point, small pieces of debris can still fly out, posing a safety hazard. Therefore, a protective space for refuge must be built before blasting.

[0003] Currently, most common shelters are constructed by splicing together panels with sound-insulating materials and then securing them with screws and fasteners. However, this method has many drawbacks in practice: Firstly, the frequent disassembly and reassembly of screws and fasteners during the construction of such shelters makes the entire process cumbersome, consuming a lot of time and manpower, and greatly reducing work efficiency; secondly, shelters built with only simple sound-insulating panels have a simple internal structure and poor stability. Under the impact of blasting in metal mines, the shelter is prone to shaking, causing workers to collide with the shelter walls and get injured, making it difficult to guarantee the stability and safety of personnel inside the shelter.

[0004] Therefore, there is an urgent need for a metal mine blasting protection device that can be quickly assembled and effectively improve the stability of personnel in the protective chamber, in order to solve the shortcomings of existing protective chambers in terms of construction and personnel safety. Utility Model Content

[0005] This utility model provides a metal mine blasting protection device that can be quickly assembled and constructed.

[0006] The specific technical solution of this utility model is as follows:

[0007] A metal mine blasting protection device that can be quickly assembled includes a base plate. Folding baffles are rotatably connected to both sides of the base plate. A splicing seat is engaged between the two folding baffles at their closest ends. Two protective doors are connected to both ends of the splicing seat through an opening and closing mechanism. The opening and closing mechanism can drive the two protective doors to move closer together and clamp the base plate, the two folding baffles, and the splicing seat to form a blasting protection chamber, or drive the protective doors to move away from each other and open the blasting protection chamber for personnel to enter and exit.

[0008] Furthermore, preferably, splicing slots are provided on both sides of the splicing base, and splicing strips that are adapted to the splicing slots are provided on the adjacent end faces of the two folding baffles.

[0009] Furthermore, preferably, the opening and closing mechanism includes two symmetrically arranged synchronous racks. The ends of the two synchronous racks that are far apart from each other are connected to the inner surface of the protective gate, and the other ends are slidably disposed inside the splicing seat and precisely mesh with both sides of the same adjusting gear. The adjusting gear is rotatably disposed inside the splicing seat, and a rotating shaft is connected through the center of the adjusting gear. A rotating operating block is connected to the lower end of the rotating shaft.

[0010] Furthermore, preferably, a support rod is provided between the rotating operating block and the sitting mat. The lower end of the support rod is connected to the upper surface of the sitting mat, and the upper end rotates through the bottom of the rotating operating block and is connected to the center of the lower end face of the rotating block. The rotating block is rotatably disposed inside the rotating operating block.

[0011] Furthermore, preferably, a support pad is provided on the outer surface of the bottom end of the support pole, and the support pad is attached to the ground mat.

[0012] Furthermore, preferably, the seating mat is connected to the two folding baffles via a hinge.

[0013] Furthermore, preferably, the outer surfaces of the floor mat, the two folding baffles, the splicing seat, and the two protective doors are all covered with sound-insulating material.

[0014] The beneficial effects of this utility model are as follows: Through the ingenious design of components such as the seating pad, folding baffle, splicing base, and protective door, combined with the convenient operation of the snap-fit ​​and opening / closing mechanisms, the protective chamber can be quickly assembled and disassembled, significantly saving time and labor costs, improving work efficiency, and meeting the needs of frequent site changes and emergency evacuation in mine blasting operations. The snap-fit ​​structure of the splicing base and folding baffle is stable and reliable. The opening / closing mechanism drives the protective door to clamp all components, forming a sealed protective chamber. The support poles and support pads enhance the stability of the equipment and provide stable seating support for workers, preventing bumps and injuries, and comprehensively ensuring the safety of workers. Simultaneously, sound-insulating materials are adhered to the outer surfaces of the main components of the equipment, effectively reducing blasting noise damage, improving the shelter environment, and alleviating the psychological pressure on workers. Furthermore, the entire assembly, opening, and closing process is simple to operate, requiring no complex tools or cumbersome steps, allowing workers to quickly enter a protective state or evacuate, making it highly practical.

[0024] like Figure 1 Figure 2As shown, this embodiment provides a metal mine blasting protection device that can be quickly assembled and constructed, including a base plate 1. The base plate 1 has two folding baffles 2 rotatably connected to its two side edges via hinges 9. This connection method allows the folding baffles 2 to be flexibly flipped, facilitating closure to form a protective structure during use. A splicing seat 3 is engaged between the two adjacent ends of the two folding baffles 2. Two protective doors 5 are connected to both ends of the splicing seat 3 via an opening and closing mechanism 4. The opening and closing mechanism 4 can drive the two protective doors 5 to move closer together and clamp the base plate 1, the two folding baffles 2, and the splicing seat 3 to form a blasting protection chamber, or drive the protective doors 5 to move away from each other, opening the blasting protection chamber for personnel access.

[0025] like Figure 3 Figure 4 As shown, the snap-fit ​​structure between the splicing base 3 and the two folding baffles 2 is as follows: Splicing slots 301 are provided on both sides of the splicing base 3, and splicing strips 201, adapted to the splicing slots 301, are offset from the adjacent ends of the two folding baffles 2. When the two folding baffles 2 are flipped and brought closer together, the splicing strips 201 securely engage with the splicing slots 301, achieving a tight snap-fit ​​between the splicing base 3 and the folding baffles 2. This snap-fit ​​structure is simple yet robust, laying the foundation for forming a complete protective chamber.

[0026] like Figure 3 As shown, the opening and closing mechanism 4 includes two symmetrically arranged synchronous racks 401. One end of each rack is connected to the inner surface of the protective gate 5, while the other end slides inside the splicing base 5 and precisely meshes with both sides of the same adjusting gear 402. The adjusting gear 402 is rotatably mounted inside the splicing base 5. A rotating shaft 403 is centrally connected to the adjusting gear 402, and a rotating operating block 404 is connected to the lower end of the rotating shaft 403. By rotating the operating block 404 clockwise or counterclockwise, the adjusting gear 402 can be driven to rotate, thereby causing the two synchronous racks 401 to move closer or further apart, thus closing or opening the protective gate 5. The operation is convenient and effortless.

[0027] like Figure 3 Figure 5As shown, a support rod 6 is also provided between the rotating operating block 404 and the ground pad 1. The lower end of the support rod 6 is connected to the upper surface of the ground pad 1, and the upper end rotates through the bottom of the rotating operating block 404 and is connected to the center of the lower end face of the rotating block 7. The rotating block 7 is rotatably located inside the rotating operating block 404. A support pad 8 is also provided on the outer surface of the bottom end of the support rod 6, and the support pad 8 is attached to the ground pad 1. This design ensures the flexible rotation of the opening and closing mechanism 4 while providing strong support for the entire protective equipment, significantly improving its stability. During blasting operations, workers can sit safely on the support pad 8 and hold the support rod 6 to maintain their balance, effectively avoiding the risk of injury from impacts caused by shaking the protective chamber due to blasting.

[0028] To enhance the sound insulation of the protective equipment and reduce the harm of blasting noise to workers, high-quality sound insulation material is adhered to the outer surfaces of the ground mat 1, folding baffle 2, splicing seat 3, and protective barrier 5. This not only creates a relatively quiet shelter environment for workers but also helps reduce psychological stress, enabling them to maintain a more stable mood and clear thinking during blasting operations.

[0029] Working Principle: Before use, place the base plate 1 stably on a flat surface. At this time, the splicing seat 3 is suspended directly above the base plate 1 under the support of the protective door 5 and the support pole 6, with the protective door 5 in the open position. During operation, the two folding baffles 2 are flipped towards the center using the hinge 9 until the splicing clip 201 is securely engaged in the splicing slot 301 on the side of the splicing seat, completing the engagement between the folding baffles 2 and the splicing seat 3. During blasting operations, workers can quickly enter the protective chamber formed by the base plate 1, folding baffles 2, and splicing seat 3 through the open protective door 5. Subsequently, rotating the rotating operating block 404 clockwise drives the adjusting gear 402 to rotate clockwise, causing the two synchronous racks 401 to move closer together, causing the protective door 5 to move closer together and clamp the base plate 1, folding baffles 2, and splicing seat 3, forming a well-sealed blasting protective chamber, providing all-round protection for workers and effectively resisting the impact and flying debris generated by the blast. Inside the protective chamber, personnel sit on the support pad 8 and hold the support pole 6 to maintain stability, effectively avoiding the risk of collision and injury caused by the shaking of the protective chamber due to the blast impact.

[0030] The snap-fit ​​design of the folding baffle 2 and the splicing base 3 of this protective equipment, combined with the clamping effect of the protective door 5, not only enables the rapid construction of the protective chamber but also ensures its sturdiness and airtightness, effectively guaranteeing the safe and stable protective effect. The easy operation of the protective door 5 further facilitates the rapid construction and dismantling of the protective chamber, effectively compensating for the shortcomings of traditional protective chambers in terms of construction efficiency and personnel safety, and significantly improving the overall safety and work efficiency of mine blasting operations.

[0031] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
