Technical Field

[0001] This utility model relates to the technical field of blasting in mining engineering, specifically a blasting safety protection device for mining engineering. Background Technology

[0002] In mining operations, blasting is one of the core steps in obtaining ore resources. However, the dangerous factors generated during blasting, such as flying rocks, shock waves, dust and noise, can pose serious safety hazards to surrounding equipment, personnel and the environment. Therefore, it is necessary to control the spread of risks through safety protection devices. As disclosed in announcement number CN219869342U, a blasting safety protection device for mining engineering includes a protective plate. Connecting blocks are fixedly connected to the top and bottom of the left side of the protective plate, and connecting grooves for use with the connecting blocks are opened at the top and bottom of the right side of the protective plate. A movable groove is opened on the right side of the inner cavity of the protective plate, and a dual-axis motor is fixedly connected to the inner cavity of the movable groove. Threaded rods are fixedly connected to the top and bottom output shafts of the dual-axis motor. By inserting the connecting blocks into the connecting grooves and then starting the dual-axis motor to drive the two threaded rods to rotate, the threaded rods drive the threaded cylinders to insert into the slots, thereby assembling the two protective plates and expanding the protective area of ​​the device. The inclusion of casters allows the user to easily move the protective plate, and an electric push rod pushes the movable plate downwards, causing the limiting cone to insert downwards into the soil, increasing the stability of the protective plate. However, existing technologies suffer from the following problems: lack of reinforcement mechanisms to assist in supporting the entire device, resulting in poor stability during use; falling fragments directly impact the reinforcing plate, causing dents and damage; and difficulty in maintenance and replacement. For example, the comparative patents listed above have this problem. Therefore, this utility model provides a blasting safety protection device for mining engineering to solve the problems mentioned above. Utility Model Content

[0016] 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.

[0017] Please see Figures 1-6 The present invention provides the following technical solution: To address the problems in existing technologies, such as the lack of reinforcement mechanisms to support the entire device, poor stability during use, dents caused by falling debris directly impacting the reinforcing plate, and difficulty in maintenance and replacement, this solution provides a blasting safety protection device for mining engineering. The device includes a protective barrier 1 and positioning pins 3. A reinforcement component is provided on the side of the protective barrier 1 away from the blasting area. This component includes a fixed mounting post 5 fixed to the side of the protective barrier 1 away from the blasting area, a removable reinforcement bearing post 6 inserted into the fixed mounting post 5, a base plate 7 fixed to the lower end of the reinforcement bearing post 6, and a positioning pin 12. A buffer protection component is also provided on the side of the protective barrier 1 closest to the blasting area. This component includes a protective plate 13, multiple sets of connectors between the protective plate 13 and the protective barrier 1, and a replaceable buffer pad 16 glued and fixed to the side of the protective plate 13 away from the protective barrier 1. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, first, hold the handle 4 in the middle of the guardrail 1 and move the guardrail 1 to the position where safety protection is required for blasting in mining engineering. The upper end of the guardrail 1 is fixed with a protective top plate 2, and the bottom of the guardrail 1 is fixed with a positioning pin 3. The guardrail 1 is placed on the ground, and at the same time, the positioning pin 3 is inserted into the ground to position the guardrail 1. Combined with the setting of the reinforcement components, the fixed installation column 5 is equipped with a return spring 8 inside. The upper and lower ends of the fixed installation column 5 are telescopically connected with movable limit blocks 9. The movable limit blocks 9 abut against the movable end of the return spring 8, and the front and rear ends of the movable limit blocks 9 are fixedly connected with movable blocks 10. Furthermore, the movable limiting block 9 is inserted into the fixed slot 11, and the right side of the movable limiting block 9 matches the upper end of the reinforcing bearing column 6. The upper end of the reinforcing bearing column 6 is inserted into the fixed mounting column 5. At the same time, the reinforcing bearing column 6 presses against the movable limiting block 9, causing the movable limiting block 9 to slide and extend within the fixed mounting column 5. The movable limiting block 9 drives the movable block 10 to slide on the outside of the fixed mounting column 5. The movable limiting block 9 presses against the return spring 8, causing the return spring 8 to undergo elastic deformation. When the reinforcing bearing column 6 is fully inserted... When the fixed installation column 5 is in place, the return spring 8 restores its elastic deformation and pushes the movable limit block 9 into the fixed groove 11 to limit the distance between the reinforced support column 6 and the fixed installation column 5. In addition, the bottom of the reinforced support column 6 is fixed with a base plate 7, which is placed on the ground. The fixing pin 12 is then inserted through the middle of the base plate 7, and the lower end of the fixing pin 12 is inserted into the ground. By setting up the reinforcement components, the contact area between the device and the ground is increased, and the device is provided with auxiliary support, thereby improving the stability of the device during safe use and preventing it from tipping over. In addition, such as Figure 1 , Figure 2 and Figure 6 As shown, the protective guardrail 1 is also equipped with a buffer protection component on the side near the blast. The connecting component includes a buffer rod 14 fixed to the side of the protective plate 13 near the protective guardrail 1 and a buffer spring 15 sleeved on the outer surface of the buffer rod 14. The movable end of the buffer spring 15 abuts against the protective guardrail 1. When the falling debris hits the buffer pad 16, it impacts the protective plate 13. The protective plate 13 causes the buffer rod 14 to slide between itself and the protective guardrail 1, and compresses the buffer spring 15, causing the buffer spring 15 to undergo elastic deformation. This provides a good buffer protection effect, preventing direct impact on the protective guardrail 1. In addition, the buffer pad 16 can prevent debris from directly contacting the protective plate 13 and causing scratches and dents, thus extending the service life of the entire device.
