Description

Technical Field

[0001] The utility model belongs to the technical field of blasting, and particularly relates to a blasting hole plugging device. Background Art

[0002] In the implementation process of modern blasting engineering, the plugging of blasting holes plays a crucial role. This link not only concerns the success or failure of blasting operations, but is also a key step in ensuring project safety and environmental protection. By adopting scientific and reasonable plugging techniques, the potential impact of explosive substances on the surrounding environment during blasting can be significantly reduced, such as reducing harmful factors like flying rocks, shock waves, and vibrations. This refined management not only ensures the safety of personnel in the construction area, but also maximally protects surrounding buildings, facilities, and the ecological environment from damage.

[0003] In the Chinese patent with the publication number CN217110699U, a blasting hole plugging device is mentioned, which can plug the blasting hole through an outer expansion cylinder. The outer expansion cylinder includes split pieces distributed in a trumpet shape. On the one hand, it is convenient for the outer expansion cylinder to be installed in the blasting hole. On the other hand, in combination with a pressing head, the split pieces can be opened and expanded, so that the split pieces are firmly pressed against the hole wall of the blasting hole, and the opened and expanded split pieces form a resistance to the direct impact of explosives in the blasting hole. However, this plugging device has deficiencies in fixing with the inner wall of the blasting hole, and its firmness is not strong enough. This leads to the possibility that the device may be ejected from the blasting hole due to huge impact forces during blasting. This situation not only affects the normal function of the plugging device, but also greatly reduces its stability during use, thus possibly having an adverse impact on the blasting effect and safety. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a blasting hole plugging device to solve the problems raised in the above background art.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figures 1 to 4 as shown, a blasting hole plugging device includes:

[0029] plugging cylinder 1;

[0030] Fixing mechanism 2, the fixing mechanism 2 includes an adjusting rod 21, a large bevel gear 22, a fixing frame 23, a reinforcement mechanism 24 and an adjusting handle 25. The adjusting rod 21 is installed in the middle of the top end of the plugging cylinder 1 through a bearing. A number of large bevel gears 22 and reinforcement mechanisms 24 are provided, and a number of large bevel gears 22 are all installed on the outer surface of the adjusting rod 21. The fixing frame 23 is installed on the inner top wall of the plugging cylinder 1, and a number of reinforcement mechanisms 24 are all installed on the outer wall of the fixing frame 23. The adjusting handle 25 is installed at the top end of the adjusting rod 21;

[0031] Buffer mechanism 5, the buffer mechanism 5 is installed at the bottom end of the fixing mechanism 2, and the buffer mechanism 5 is located at the lower side inside the plugging cylinder 1. The buffer mechanism 5 buffers the impact force received by the plugging cylinder 1.

[0032] As Figures 1 to 3 can be seen, a number of inlet and outlet holes 3 are provided on the upper part of the outer surface of the plugging cylinder 1, a number of through holes 4 are provided on the lower part of the outer surface of the plugging cylinder 1, and a buffer head 6 is installed at the bottom end of the buffer mechanism 5;

[0033] The reinforcement mechanism 24 includes an adjusting screw 241, a small bevel gear 242, a reinforcement rod 243 and a limiting plate 244. The adjusting screw 241 is installed on the outer wall of the fixing frame 23 through a bearing. The small bevel gear 242 is installed at one end of the adjusting screw 241. The reinforcement rod 243 is installed on the outer surface of the adjusting screw 241. The limiting plate 244 is installed on the outer surface of the reinforcement rod 243.

[0034] As described above, first, insert the plugging cylinder 1 into the blasting hole. Then, hold the adjusting handle 25 to drive the adjusting rod 21 to rotate. The adjusting rod 21 then drives a number of large bevel gears 22 thereon to rotate. Through the meshing transmission between the large bevel gear 22 and the small bevel gear 242, the adjusting screw 241 is driven to make the reinforcement rod 243 move outward. In this way, a number of reinforcement rods 243 can all pass through the corresponding inlet and outlet holes 3 and be inserted into the inner wall of the blasting hole, thereby firmly fixing the plugging cylinder 1 and the blasting hole together. This fixing method effectively prevents the plugging cylinder 1 from being pushed out or displaced by the impact force during blasting, thereby improving the stability of the entire plugging device and reducing the risk of the device being pushed out of the blasting hole. In addition, through the effective plugging of the blasting hole by the plugging device, the flying stones and fragments generated during blasting can also be reduced, further improving the safety and ensuring the blasting effect of the explosive inside the blasting hole.

[0035] Specifically, referring to Figures 1 to 3 shown, the small bevel gear 242 meshes with the large bevel gear 22. Both the reinforcement rod 243 and the buffer head 6 are provided with a conical structure. The fixing frame 23 is provided with a pentagonal structure.

[0036] As described above, when the large bevel gear 22 rotates, it can drive the small bevel gear 242 to rotate, realizing the transmission of power, which is conducive to the insertion of the conical reinforcement rod 243 into the inner wall of the blasting hole. Also, the conical buffer head 6 can disperse the impact force received, and the pentagonal structure of the fixed frame 23 can increase the structural stability and load-bearing capacity.

[0037] Embodiment 2:

[0038] Reference Figure 4 As shown, the buffer mechanism 5 includes a buffer plate 51, a sliding groove 52, a sliding block 53, a fixing pin 54, a spring 55, a buffer rod 56, a buffer block 57 and a shock absorber 58. The buffer plate 51 is installed at the bottom end of the fixed frame 23. The sliding groove 52 is opened at the bottom end of the buffer plate 51. The sliding block 53 is installed inside the sliding groove 52. The fixing pin 54 is installed on the outer wall of the sliding block 53. The spring 55 is installed on the outer surface of the fixing pin 54. The buffer rod 56 is installed at the bottom end of the sliding block 53 through a connecting seat. The buffer block 57 is installed at the bottom end of the buffer rod 56 through a connecting seat. The shock absorber 58 is installed between the opposite surfaces of the buffer plate 51 and the buffer block 57.

[0039] As described above, when the buffer head 6 is impacted by blasting, its conical structure first preliminarily disperses the impact force. Subsequently, the buffer head 6 pushes the buffer block 57 to move into the inside of the plugging cylinder 1, thereby causing the outer surfaces of the upper parts of several buffer rods 56 to move outward. These moving buffer rods 56 further push several sliding blocks 53 to slide in the corresponding sliding grooves 52. The sliding of the sliding blocks 53 further pushes several fixing pins 54 to pass through the through holes 4 and insert into the inner wall of the blasting hole together, thus realizing the re-reinforcement of the plugging cylinder 1. This reinforcement method ensures the plugging quality of the plugging device for the blasting hole. At the same time, during the sliding process of the sliding blocks 53, they will squeeze the spring 55 to make it contract. At this time, the elasticity of the spring 55 and the shock-absorbing effect of the shock absorber 58 jointly convert and disperse the impact force received by the buffer block 57, further improving the buffer effect and effectively reducing the possible damage to the plugging device caused by the impact force.

[0040] Preferably, as shown in Figure 4 the sliding groove 52 and the sliding block 53 are both arranged in a cross-shaped structure. The fixing pin 54 is located inside the through hole 4. The diameter of the buffer block 57 is the same as the inner diameter of the plugging cylinder 1.

[0041] As described above, it makes the cross-shaped sliding block 53 not break away from the cross-shaped sliding groove 52, and also ensures that the sliding block 53 and the fixing pin 54 connected thereto can accurately move along the predetermined track, enabling the fixing pin 54 to pass through the through hole 4 and directly contact the inner wall of the blasting hole, which is conducive to the movement of the buffer block 57 inside the plugging cylinder 1 to buffer the impact force.

[0042] Application example:

[0043] This design is applied in engineering environments where blasting operations are required, especially in scenarios such as mine exploitation, tunnel excavation, rock fragmentation, and building demolition. By setting the fixing mechanism 2, this design can firmly fix the plugging cylinder 1 on the inner wall of the blasting hole, preventing the plugging cylinder 1 from being pushed out or displaced by the impact force during the blasting process, thus ensuring the stability of the plugging device, improving the blasting effect. At the same time, by setting the buffer mechanism 5, it can absorb and disperse the impact force generated during blasting, reducing the damage to the plugging device. Moreover, the impact force can also push the fixing pin 54 further into the inner wall of the blasting hole to achieve secondary reinforcement, significantly reducing the risk of accidents during the blasting process. This blasting hole plugging device has broad application prospects and remarkable benefits in engineering environments such as mine exploitation, tunnel excavation, rock fragmentation, and building demolition where blasting operations are required.

[0044] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
