Description

Technical Field

[0001] This utility model relates to the technical field of sealing blast holes in mines, and in particular to a sealing device for blast holes in mines. Background Technology

[0002] In modern blasting engineering, sealing the blast holes is a crucial step. Proper sealing techniques can effectively reduce the impact of explosive materials on the surrounding environment and ensure project safety.

[0003] Among existing mine blast hole sealing devices, such as the blast hole sealing device disclosed in utility model patent application number 202420022212.9, this utility model pushes the support tube to open the connection between the first connecting rod and the second connecting rod outwards from the blast hole, thereby achieving the effect of quickly fixing the sealing bag, improving the problem of time-consuming and labor-intensive installation during the sealing process, and making the sealing device more firmly connected in the blast hole, reducing the possibility of the sealing device flying out of the blast hole, with high adaptability, improving the construction efficiency and safety of blasting projects.

[0004] However, the process of sealing blast holes in mines is complicated by the need to fix and adjust the equipment bit by bit, which increases the difficulty of operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mine blast hole sealing device that, by setting a water spraying mechanism and a fixing mechanism, makes it easier to fix the equipment during the sealing process of mine blast holes, reduces the difficulty of operation, and allows for directional water spraying to extinguish dust.

[0006] This utility model discloses a mine blast hole sealing device, which includes a buffer mechanism; it also includes a water spraying mechanism, a sealing mechanism, and a fixing mechanism. The water spraying mechanism is installed on the buffer mechanism, the sealing mechanism is installed on the buffer mechanism, and the fixing mechanism is installed on the buffer mechanism.

[0007] The buffer mechanism provides buffering, the water spraying mechanism sprays water, the sealing mechanism seals, and the fixing mechanism fixes. The sealing mechanism injects water in one direction, the fixing mechanism secures the equipment, the buffer mechanism buffers the explosion, and the explosion shock wave impacts the water spraying mechanism to spray water for dust suppression. This makes it easier to fix the equipment during the sealing of mine blast holes, reduces the difficulty of operation, and allows for directional water spraying for dust suppression.

[0008] Preferably, the buffer mechanism includes a base, a telescopic cylinder, and a spring, with the telescopic cylinder slidably mounted on the base via the spring; the spring supports the telescopic cylinder during an explosion, thus buffering the telescopic cylinder when it is subjected to a shock wave.

[0009] Preferably, the water spraying mechanism includes a baffle plate, six sets of springs, and six sets of plugs. The baffle plate is slidably mounted on the telescopic cylinder via the six sets of springs. The baffle plate is equipped with six sets of plugs, and each set of plugs extends into the water spray nozzle on the telescopic cylinder for sealing. The baffle plate is contracted by impact waves, which simultaneously causes the plugs to retract. The water in the telescopic cylinder is squeezed by the baffle plate and then sprayed out from the water spray nozzle on the telescopic cylinder.

[0010] Preferably, the sealing mechanism includes a second baffle and a third spring. The second baffle is slidably installed inside the telescopic cylinder by the third spring. Water is injected by pushing open the second baffle, and the third spring supports the second baffle to seal the equipment and prevent water leakage.

[0011] Preferably, the fixing mechanism includes a pull frame, four springs, six sets of support feet, six sets of support rods, and two sets of pull rings. The pull frame is slidably mounted on the base via four springs, and the six sets of support feet are rotatably mounted on the base. Each set of support feet is rotatably connected to the pull frame via a set of support rods, and the two sets of pull rings are rotatably mounted on the pull frame. By pulling the pull rings, the pull frame moves. After the pull frame moves, the support rods retract, causing the support feet to retract and extend into the opening. The support feet are then opened and locked into the opening by the support of four springs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the sealing mechanism enables unidirectional water injection, the fixing mechanism secures the equipment, the buffer mechanism buffers the explosion, and the explosion shock wave impacts the water spraying mechanism to spray water for dust suppression. This makes it easier to secure the equipment during the sealing of mine blast holes, reduces the difficulty of operation, and allows for directional water spraying for dust suppression.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 4 As shown, a mine blast hole sealing device includes a buffer mechanism 1, a water spraying mechanism 2, a sealing mechanism 3, and a fixing mechanism 4. The water spraying mechanism 2 is installed on the buffer mechanism 1, the sealing mechanism 3 is installed on the buffer mechanism 1, and the fixing mechanism 4 is installed on the buffer mechanism 1.

[0021] The buffer mechanism 1 provides buffering, the water spraying mechanism 2 sprays water, the sealing mechanism 3 seals, and the fixing mechanism 4 fixes.

[0022] The buffer mechanism 1 includes a base 11, a telescopic cylinder 12 and a spring 13. The telescopic cylinder 12 is slidably mounted on the base 11 via the spring 13.

[0023] The water spraying mechanism 2 includes a baffle 21, six sets of springs 22 and six sets of plugs 23. The baffle 21 is slidably mounted on the telescopic cylinder 12 by the six sets of springs 22. The baffle 21 is equipped with six sets of plugs 23, and each set of plugs 23 extends into the water spray nozzle on the telescopic cylinder 12 for sealing.

[0024] The sealing mechanism 3 includes a second baffle 31 and a third spring 32. The second baffle 31 is slidably installed inside the telescopic cylinder 12 via the third spring 32.

[0025] The fixing mechanism 4 includes a pull frame 41, a spring 42, six sets of support feet 43, six sets of support rods 44, and two sets of pull rings 45. The pull frame 41 is slidably mounted on the base 11 via the spring 42. The six sets of support feet 43 are rotatably mounted on the base 11. Each set of support feet 43 is rotatably connected to the pull frame 41 via a set of support rods 44. The two sets of pull rings 45 are rotatably mounted on the pull frame 41.

[0026] Water is injected by pushing open the baffle 2 31. The baffle 2 31 is supported by the spring 3 32 to seal the equipment and prevent water leakage. The pull ring 45 is pulled to move the pull frame 41. After the pull frame 41 moves, the support rod 44 retracts, which pulls the support foot 43 to retract and extend into the hole. The support foot 43 is supported by the spring 42 to open and lock into the hole. When the explosion occurs, the spring 1 13 supports the telescopic cylinder 12 to buffer it when it is subjected to the shock wave. At the same time, the shock wave hits the baffle 1 21, causing the baffle 1 21 to retract and drive the plug 23 to move backward. The water in the telescopic cylinder 12 is squeezed by the baffle 1 21 and sprayed out from the water spray nozzle on the telescopic cylinder 12 to extinguish dust. This makes it easier to fix the equipment during the sealing of the mine blast hole, reduces the difficulty of operation, and allows for directional water spraying to extinguish dust.

[0027] like Figures 1 to 4 As shown, this utility model discloses a mine blasting hole sealing device. During operation, water is injected to open the baffle 21 for water injection. The baffle 21 is supported by the spring 32 to seal the device and prevent water leakage. Pulling the pull ring 45 moves the pull frame 41. After the pull frame 41 moves, the support rod 44 retracts, which pulls the support foot 43 to retract and extend into the hole. The support foot 43 is supported by the spring 42 to open and lock into the hole. During the explosion, the spring 13 supports the telescopic cylinder 12 to buffer the shock wave. At the same time, the shock wave hits the baffle 21, causing the baffle 21 to retract and drive the plug 23 to move backward. The water inside the telescopic cylinder 12 is squeezed by the baffle 21 and sprayed out from the water nozzle on the telescopic cylinder 12 to extinguish dust.

[0028] The main function achieved by this utility model is: in the process of sealing blast holes in mines, by setting up a water spraying mechanism and a fixing mechanism, the equipment can be fixed more easily during the sealing process of blast holes in mines, reducing the difficulty of operation, and water spraying can be carried out in a directional manner to eliminate dust.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
