[0002] Engineering blasting is an engineering technique that uses the explosive energy of explosives to destroy, demolish, or throw media (such as rocks and concrete). It is widely used in mining, tunneling, building demolition, road construction, military engineering, and geological disaster prevention.

[0003] In engineering blasting, blasting holes are pre-drilled holes in media such as rock and concrete to hold explosives and detonation devices, and are a key structure for carrying out blasting. Their diameter, depth, and spacing are precisely designed according to the blasting target (such as fragmentation and throwing direction), and are commonly used in mining, tunnel construction, and other fields.

[0004] The main function of a blasting hole sealing device is to prevent leakage of explosives and control the blasting effect. It can effectively seal blasting holes, prevent explosive spillage, and ensure the accuracy and safety of the blasting effect. In short, blasting hole sealing devices for engineering blasting have the function of preventing leakage of explosives and controlling the blasting effect, playing an important role in ensuring the safety of engineering construction and the accuracy of blasting results. Application number CN202323631965.4 provides a blasting hole sealing device for engineering blasting. Through the action of springs, buffer discs, and other structures, it can buffer and offset the shock wave generated by the explosion, thus providing good protection. However, this device cannot secure the fixing disc to the rock portion during use, resulting in relatively low stability even when the bolts loosen.

[0005] Therefore, it is necessary to provide a blast hole sealing device for engineering blasting to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figure 1 , Figure 2 and Figure 3 A blast hole sealing device for engineering blasting includes: a mounting rod 1, and a reinforcing component 2 is provided at the bottom of the mounting rod 1; The reinforcement component 2 includes a reinforcement plate 21 fixedly disposed on the bottom side of the mounting rod 1. The top of the reinforcement plate 21 is provided with a slot 22, and a reinforcement block 23 is rotatably disposed on the inner side of the slot 22. The top of the reinforcement block 23 is provided with a locking tooth 24.

[0018] In its normal state, the reinforcing block 23, under the influence of the ejector spring 26, will have its locking teeth 24 extending beyond the outer edge of the reinforcing plate 21. When the sealing device is used, the mounting rod 1 and the reinforcing plate 21 are inserted into the blast hole. Under the action of the external hole wall, the reinforcing block 23 rotates inward, allowing the reinforcing plate 21 to enter the hole. When the blast occurs, a shock wave is generated, which exerts an outward pushing force on the reinforcing plate 21. At this time, since the reinforcing block 23 is provided with locking teeth 24 on its edge, when there is a tendency to move outward, the edge of the locking teeth 24 will engage with the cracks or irregular positions on the inner wall of the hole, thereby reinforcing the position of the mounting rod 1 in the hole and improving the stability of the device.

[0019] A sliding ring 25 is provided on the inner side of the slot 22. The inner side of the reinforcing block 23 is slidably connected to the outer side of the sliding ring 25. An ejector spring 26 is provided on the circumferential side of the sliding ring 25. The top of the ejector spring 26 is fixedly connected to the left side of the reinforcing block 23.

[0020] The two reinforcing blocks 23 are also provided with a rope for unlocking on the opposite side. The top of the rope extends to the top of the mounting rod 1. When the rope is pulled, the two reinforcing blocks 23 rotate inward against the push-out spring 26. The outer teeth 24 of the two reinforcing blocks 23 are smaller than the outer edge of the reinforcing plate 21, so the device can be pulled out.

[0021] A buffer plate 3 is provided on the periphery of the mounting rod 1 and below the reinforcing plate 21, and can slide up and down. A guide rod 4 is provided vertically on the top of the buffer plate 3. The periphery of the guide rod 4 is slidably connected to the inner side of the reinforcing plate 21, and a limit piece 5 is provided on the top of the guide rod 4.

[0022] By incorporating a buffer spring 6 and a buffer disc 3, when the buffer disc 3 is subjected to a shock wave, it slides upward on the circumferential side of the mounting rod 1, while simultaneously compressing the buffer spring 6 to buffer the impact.

[0023] A buffer spring 6 is provided on the periphery of the guide rod 4. The bottom end of the buffer spring 6 is fixedly connected to the top of the buffer plate 3, and the top end of the buffer spring 6 is fixedly connected to the bottom of the reinforcing plate 21.

[0024] An elastic airbag 7 is provided on the outer side of the reinforcing plate 21, and an inflation tube 8 is provided on the inner side of the elastic airbag 7 and inside the mounting rod 1.

[0025] By incorporating an elastic airbag 7, when encountering irregular holes, the elastic airbag 7 is inflated to prevent gravel from flying everywhere.

[0026] A fixing plate 9 is threadedly connected to the top of the side of the mounting rod 1, which can move up and down. A reinforcing nut 10 is provided at the bottom of the fixing plate 9 and on the side of the mounting rod 1. The inner side of the reinforcing nut 10 is threadedly connected to the side of the mounting rod 1. Four bolt fasteners 11 are provided on the inner side of the fixing plate 9.

[0027] When the bottom of the fixed plate 9 is pressed against the outside of the blast hole, it is fixed to the outside of the blast hole by using four bolt fasteners 11; at the same time, a reinforcing nut 10 is provided. When it is necessary to adjust the distance between the fixed plate 9 and the reinforcing plate 21, the fixed plate 9 can be rotated first to adjust the position, and then the reinforcing nut 10 can be rotated against the bottom of the fixed plate 9 to fix the adjusted position by friction.

[0028] The working principle of the blast hole sealing device for engineering blasting provided by this utility model is as follows: Step 1: When using the device, if it is necessary to adjust the distance between the fixed plate 9 and the reinforcing plate 21, the fixed plate 9 can be rotated first to adjust the position. Then, the reinforcing nut 10 is rotated only against the bottom of the fixed plate 9, and the adjusted position is fixed by friction. Then, the mounting rod 1 and the reinforcing plate 21 are inserted into the blast hole. The fixed plate 9 is fixed to the outside of the blast hole by using four bolt fasteners 11. The elastic airbag 7 is provided. When encountering irregular holes, the elastic airbag 7 is inflated to prevent the flying of gravel. Step 2: When the explosion generates a shock wave, it will exert an outward force on the reinforcing plate 21. At this time, since the reinforcing block 23 is provided with a locking tooth 24 on its edge, when there is a tendency to move outward, the edge of the locking tooth 24 will engage with the crack or irregular position on the inner wall of the hole, thereby reinforcing the position of the mounting rod 1 in the hole and improving the stability of the device. At the same time, by providing a buffer spring 6 and a buffer plate 3, when the buffer plate 3 is subjected to a shock wave, it can slide upward on the circumferential side of the mounting rod 1, while compressing the buffer spring 6 to buffer the impact.

[0029] Compared with related technologies, the blast hole sealing device for engineering blasting provided by this utility model has the following beneficial effects: When the explosion generates a shock wave, it will exert an outward force on the reinforcing plate 21. At this time, since the reinforcing block 23 is provided with a locking tooth 24 on its edge, when there is a tendency to move outward, the edge of the locking tooth 24 will be locked into the crack or irregular position of the inner wall of the hole under the action of the ejection spring 26, thereby reinforcing the position of the mounting rod 1 in the hole and improving the stability of the device.
