Description

Technical Field

[0001] The utility model relates to the technical field of shaped charge blasting, in particular to a water-pressure shaped charge blasting pipe. Background Technique

[0002] The blasting shaped charge pipe is mainly applied to national railway, highway, subway engineering construction, mine exploitation, adit mining, coal mine exploitation and roof cutting. Since 2015, this technical product has been widely applied to the projects of China Railway, China Railway Construction, CCCC, CSCEC, Sinohydro, as well as iron ore, coal mine and military industrial system projects. Compared with the traditional smooth blasting, the shaped charge pipe smooth blasting technology can save explosives. At the same time, for the surrounding rock with very high rock integrity, the hole spacing of the peripheral holes can be greatly enlarged. After blasting, the contour line is flat, overbreak and underbreak are reduced, and the amount of shotcreting used in the later stage is decreased.

[0003] In the water-pressure shaped charge blasting, the water bag not only does not reduce the blasting effect, but can also protect the vegetation around the tunnel, reduce geological disturbance, reduce smoke and dust. Most importantly, it can save the explosive cost and reduce the construction cost. However, in the prior art, for different situations, shaped charge pipes with different lengths need to be adopted, and the production, carrying, classification and taking are all inconvenient. It is very easy to have the situation that the length cannot meet the requirements, and the length of the blasting pipe cannot be increased according to the actual needs. For this reason, we propose a water-pressure shaped charge blasting pipe. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water-pressure shaped charge blasting pipe, which is mutually matched by structures such as a first blasting pipe, a second blasting pipe and a connecting sleeve, so as to solve the problem that the lengths of the existing shaped charge blasting pipes are the same and it is inconvenient to change according to the actual situation.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A water-pressure shaped charge blasting pipe comprises a first blasting pipe. One end of the first blasting pipe is fixedly connected with a convex block. The second blasting pipe is detachably arranged outside the convex block. One end of the second blasting pipe close to the convex block is fixedly connected with a connecting block. A clamping groove is formed inside the connecting block. The convex block is inserted into the clamping groove. The outside of the mutually close ends of the first blasting pipe and the second blasting pipe is detachably provided with a connecting sleeve, and the connecting sleeve can further strengthen the connection effect between the first blasting pipe and the second blasting pipe.

[0007] Preferably, the inside of the connecting sleeve is symmetrically and threadedly connected with screw rods. One ends of the two screw rods are both fixedly connected with turning knobs. One ends of the two screw rods far away from the turning knobs are both threadedly connected with arc-shaped clamps. Elastic pads are fixedly connected to the outsides of the two arc-shaped clamps, and the elastic pads can prevent over-tight clamping and can increase the friction force at the same time.

[0008] Preferably, a through hole is provided inside the connecting sleeve and near one side of the screw rod. A round rod is movably arranged inside the two through holes. One end of each of the two round rods penetrates through the through hole and is fixedly connected to the arc-shaped clamp. The two round rods are used to limit the arc-shaped clamp, and the other ends of the two round rods extend out of the through hole.

[0009] Preferably, grooves are provided inside both the first blasting pipe and the second blasting pipe. The grooves are used to hold water or dust removal agents. Water inlet pipes are fixedly connected to the tops of the two grooves, and valves are fixedly connected to the outsides of the two water inlet pipes.

[0010] Preferably, concave holes are symmetrically provided inside the connecting block. Springs are fixedly connected inside the two concave holes. One end of each of the two springs away from the concave hole is fixedly connected to a limiting clamp. The limiting clamp is used to make the convex block and the card slot more tightly connected.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In this solution, through the cooperation of structures such as the first blasting pipe, the convex block, the second blasting pipe, the connecting block, the card slot, the limiting clamp, and the spring, it is convenient to increase the length of the blasting pipe.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached 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.

[0023] As Figure 1 - Figure 7 shown, a water pressure energy-gathering blasting tube in the illustration includes a first blasting tube 1. One end of the first blasting tube 1 is fixedly connected with a convex block 2. A second blasting tube 3 is detachably arranged outside the convex block 2. Both the first blasting tube 1 and the second blasting tube 3 are made of PVC material and can be flexibly set in length according to actual needs. One end of the second blasting tube 3 close to the convex block 2 is fixedly connected with a connecting block 4. A card slot 5 is opened inside the connecting block 4. The size of the card slot 5 is adapted to that of the convex block 2. The convex block 2 is inserted into the card slot 5. Concave holes 18 are symmetrically opened inside the connecting block 4. Springs 16 are fixedly connected inside both of the two concave holes 18. One end of each of the two springs 16 away from the concave hole 18 is fixedly connected with a limit clamp 17. The limit clamp 17 is made of rubber material. Through the cooperation of structures such as the spring 16, the limit clamp 17 and the concave hole 18, the friction between the convex block 2 and the card slot 5 can be increased, making their connection tighter. A connecting sleeve 6 is detachably arranged outside the mutually approaching ends of the first blasting tube 1 and the second blasting tube 3. The connecting sleeve 6 is made of plastic material and is used to further reinforce the first blasting tube 1 and the second blasting tube 3.

[0024] Specifically: Please refer to Figure 3 、 Figure 4 and Figure 7, symmetrically threaded inside the connecting sleeve 6 are screw rods 8. Fixedly connected to one end of each of the two screw rods 8 is a knob 7. The outside of the knob 7 is fixedly provided with indentations for amplifying friction. Threadedly connected to the end of each of the two screw rods 8 away from the knob 7 is an arc-shaped clamp 11. The arc-shaped clamp 11 is made of plastic. Fixedly connected to the outside of each of the two arc-shaped clamps 11 is an elastic pad 12. The elastic pad 12 is made of rubber. By rotating the knob 7, the knob 7 drives the screw rod 8 to rotate, thereby driving the two arc-shaped clamps 11 to approach each other. At the same time, it drives the elastic pads 12 to approach each other. The elastic pads 12 can prevent over-tight clamping and can increase friction at the same time, further strengthening the first blasting tube 1 and the second blasting tube 3, enabling the first blasting tube 1 and the second blasting tube 3 to be connected more tightly and making them more firm.

[0025] Furthermore, please refer to Figure 3 , Figure 4 and Figure 7 , inside the connecting sleeve 6 and on the side close to the screw rod 8 are through holes 10. Inside the two through holes 10 are movably arranged round rods 9. The round rods 9 are used to limit the movement range of the arc-shaped clamps 11 to ensure their horizontal movement. One end of each of the two round rods 9 penetrates through the through hole 10 and is fixedly connected to the arc-shaped clamp 11. The other end of each of the two round rods 9 extends outside the through hole 10. The two round rods 9 are slightly longer than the screw rods 8. The knob 7, the screw rods 8, and the round rods 9 are all made of plastic, with lower costs.

[0026] Furthermore, referring to Figure 5 , inside the first blasting tube 1 and the second blasting tube 3 are both provided with grooves 13. The grooves 13 are used to hold water or a dust-absorbing agent for use in conjunction with a water bag, which can further reduce dust and smoke at the site, being beneficial to environmental protection. Fixedly connected to the top of each of the two grooves 13 is a water inlet pipe 14. Fixedly connected to the outside of each of the two water inlet pipes 14 is a valve 15. Inside the water inlet pipe 14 is a sealing gasket to prevent the water or dust-absorbing agent inside the groove 13 from spilling. Through the mutual cooperation of structures such as the grooves 13, the water inlet pipes 14, and the valves 15, the dust reduction effect of the blasting tube can be improved, reducing dust pollution, being beneficial to protecting the safety of users, and enhancing the practicality of the first blasting tube 1 and the second blasting tube 3.

[0027] In addition, it should be noted that the first blasting tube 1 and the second blasting tube 3 can be used in connection with each other or separately, without affecting the blasting itself.

[0028] In summary, when it is necessary to increase the length of the first blasting pipe 1, first, the connecting sleeve 6 is sleeved outside the first blasting pipe 1. Then, the convex block 2 is aligned with the card slot 5. When the convex block 2 is inserted into the inside of the card slot 5, the limit clip 17 will be squeezed. The limit clip 17 squeezes the spring 16 under pressure, which can increase the friction force between the convex block 2 and the card slot 5, making the convex block 2 and the card slot 5 tightly connected. At the same time, the rotary knob 7 is rotated. The rotary knob 7 drives the screw rod 8 to rotate, thereby driving the two arc-shaped clips 11 to approach each other. At the same time, the elastic pads 12 are driven to approach each other. The elastic pads 12 can prevent over-tightening and can increase the friction force, further strengthening the first blasting pipe 1 and the second blasting pipe 3. At the same time, the valve 15 is loosened, and water or dust suppressant is added into the groove 13 through the water inlet pipe 14, and then the valve 15 is tightened.

Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
