Description

Technical Field

[0001] This utility model relates to the field of demolition blasting technology, specifically to a blasting device capable of multiple blasts. Background Technology

[0002] A multiple-explosive blasting device is a device that produces an explosion by igniting gunpowder in a confined space. The blasting device mainly consists of a support tube, a connecting tube, a blasting box, and an ignition device. When using the blasting device, the fuse inside the support tube is ignited by the electronic ignition device, which in turn ignites the detonator inserted into the blasting box, and the detonator detonates the blasting box.

[0003] Utility model patent CN221349902U discloses a multiple-explosion blasting device. An electronic ignition device is installed at the top of the support tube. Connecting rods are uniformly fixedly connected to the surface of the support tube. A connecting block is fixedly connected to the end of each connecting rod away from the support tube. Explosion boxes are installed on both sides of the connecting block. A connecting cover is installed on the surface of each explosion box. Connecting devices are installed on the sides of each explosion box. A fixing device is installed at the bottom of each connecting cover. Connecting tubes are installed on the sides of the support tube, with the end of each connecting tube away from the support tube located on the side of the explosion box. The connecting device includes a connecting frame, one side of which is fixedly connected to the side of the explosion box, and the connecting frame is sleeved on one side of the connecting block. The effects achieved by the aforementioned components are as follows: The blasting device mainly consists of a support pipe, a connecting pipe, a blasting box, and an ignition device. When using the blasting device, the fuse inside the support pipe is ignited by the electronic ignition device, which then ignites the detonator inserted into the blasting box, thereby detonating the explosives inside the blasting box. When using the fixing device, the connecting frame is fitted onto the surface of the connecting block, which allows the blasting box and the connecting block to be connected together effectively. This makes it very convenient to disassemble the blasting box when necessary, and the number of blasts can be controlled by disassembling the blasting box. However, in this patent, the number of blasts can be controlled by disassembling the blasting box, but after the blasting box is disassembled, the relative positions of the remaining blasting boxes are difficult to adjust, making it difficult to control the blasting direction.

[0022] In one embodiment, see Figure 1 The present invention discloses a blasting device capable of multiple blasts, comprising an initiation assembly and a charge assembly.

[0023] The detonation assembly includes a detonation tube 1 and a detonator 2 disposed inside the detonation tube 1.

The installation channels 7 communicate with the interior of each explosive loading unit 6. The adjusting members 4 rotate circumferentially along the axis of the detonation tube 1 under the action of external force to adjust the spacing between the supports, thereby adjusting the spacing between the explosive loading units 6.

[0024] Further, see Figure 4 The detonator 1 includes an outer cylinder 101 and an inner support column 102 connected to the cylinder 101. There is a gap between the cylinder 101 and the inner support column 102 to form a detonation cavity 3.

[0025] Preferably, the cylinder 101 is a hollow cylinder with an inner support column 102 located at the center of the cylinder 101.

[0026] Further, see Figure 1 , 4 The outer wall of the cylinder 101 is provided with an installation cavity 8, which is connected to the detonation cavity 3; the detonator 2 is installed on the cylinder 101; the adjusting component 4 includes an adjusting ring 401 provided in the installation cavity 8 and an adjusting plate 402 slidably provided in the adjusting ring 401, and a locking component 403 is detachably provided between the adjusting plate 402 and the adjusting ring 401.

[0027] Preferably, the mounting cavity 8 is located in the middle of the cylinder 101, and the mounting cavity 8 divides the cylinder 101 into two parts, with the two sets of cylinders 101 connected by the inner support column 102.

[0028] Preferably, there is a gap between the adjusting ring 401 and the outer wall of the cylinder 101 to form a sliding cavity 9, the inner wall of the adjusting ring 401 is provided with a connecting groove 10, and the adjusting plate 402 is provided with a slider 11 that is slidably connected to the connecting groove 10.

[0029] Preferably, the locking component 403 includes a locking stud provided on the adjusting plate 402. The adjusting plate 402 is provided with a locking screw hole 12 that is threadedly connected to the locking stud. After the adjusting plate 402 is inserted into the sliding cavity 9, the slider 11 is slidably connected to the connecting groove 10. At this time, the position between the adjusting plate 402 and the adjusting ring 401 is still in an active state. The adjusting plate 402 will fall out of the sliding cavity 9. By rotating the locking stud to abut against the outer wall of the cylinder 101, the slider 11 on the adjusting plate 402 is pushed into the connecting groove 10, thereby connecting the adjusting plate 402 and the adjusting ring 401.

[0030] Preferably, the adjusting plate 402 is provided with a through hole that communicates with the detonation chamber 3.

[0031] In the above configuration, the inner support column 102 inside the detonating tube 1 connects the two-part tube 101 and forms a detonation chamber 3 inside the tube 101, which facilitates the placement of the detonator 2 (the detonator 2 adopts an electronic ignition device in the existing structure, such as the YF-29 model electronic ignition device), and the fuse is placed in the detonation chamber 3. Of course, in order to ensure the connection between the detonator 2 and the fuse, a through hole can be opened at the closed end of the upper tube 101 for the fuse to pass through; the other end of the fuse can be led out from the through hole.

[0032] Further, see Figure 2 The support member 5 includes a support tube 501 and a clamping frame 502 disposed on the support tube 501. The support tube 501 is hollow inside and has an installation channel 7. The support tube 501 has a guide hole 13 on the outside that communicates with the installation channel 7.

[0036] Preferably, the charge box 601 is a hollow rectangular body with a "U" shaped cross-section in the vertical direction and a wire hole 20 for the detonator to pass through.

[0037] Preferably, the box cover 18 is provided with a sealing screw 21, and the medicine box 601 is provided with a sealing screw hole 22. The sealing screw 21 is threadedly connected to the sealing screw hole so that the box cover 18 covers the medicine box 601. The bottom end of the box cover 18 is provided with a sealing plate 23 located at the upper end of the slot 16. After the box cover 18 is connected to the medicine box 601, the sealing plate 23 abuts against the top end of the partition plate 19.

[0038] Preferably, the card slot 16 is provided with a rubber sealing layer.

[0039] Further, see also Figure 2 , 3 The medicine box 601 is provided with vertical connecting grooves 2410 and vertical clamping joints 25 connected to each other on the side end adjacent to the slot 16. A sealing gasket is provided on the inner wall of the vertical connecting groove 2410.

[0041] Preferably, the medicine box 601, the clamping frame 502, the snap-fit ​​plate 17, and the box cover 18 are all arc-shaped.

[0042] In the above configuration, the blasting explosive is stored in a charging box 601. A fuse is connected to a detonator inside the charging box 601, and the fuse ignites the detonator, thus detonating the charging box 601. The charging boxes 601 are connected to vertical connecting slots 2410 via vertical clamps 25, allowing the number of charging boxes 601 on the same support pipe 501 to be increased or decreased, thereby increasing the amount of blasting explosive. If there are two or more charging boxes 601 connected to the same support pipe 501, the partition plate 19 between adjacent charging boxes 601 can be removed. During the installation of the blasting explosive, the two or more charging boxes 601 are internally connected, facilitating the installation process. When it is necessary to increase or decrease the number of charge boxes 601 (i.e., increase or decrease the number of support tubes 501 to increase or decrease the number of charge boxes 601 around the detonator 1), the number of adjustment plates 402 can be increased or decreased, thereby increasing or decreasing the number of support tubes 501, and thus increasing or decreasing the number of charge boxes 601. The position of the charge box 601 relative to the detonator 1 can be adjusted by adjusting the position of the adjustment plates 402 along the sliding cavity 9. Of course, the position of the charge box 601 connected to the support tube 501 relative to the support tube 501 can also be adjusted.

[0043] In this embodiment, by setting the detonating tube 1 as the center of the entire device, and setting the adjusting plate 402 on the detonating tube 1, the amount of explosive can be controlled by increasing or decreasing the number of adjusting plates 402 (and simultaneously increasing or decreasing the number of support pipes 501 and explosive boxes 601 connected to the adjusting plates 402). The spacing between adjacent adjusting plates 402 can be adjusted to adjust the position between explosive boxes 601 and control the direction of explosive detonation. At the same time, the number of explosive boxes 601 connected to the same support pipe 501 can be increased or decreased individually, and the position of the explosive box 601 relative to the support pipe 501 can be adjusted to control the position of the explosive box 601 (fine-tuning the position of the explosive box 601 relative to the detonating tube 1). During the blast, the fuse and detonator are ignited by the ignition device, thereby causing the explosive in the explosive box 601 to explode.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
