Description

Technical Field

[0001] The utility model relates to the technical field of deep hole blasting, in particular to a deep hole blasting device. Background Art

[0002] Civil blasting projects are widely used in infrastructure projects such as mining, water conservancy and hydropower, railways, and highways. During blasting construction, it is necessary to drill holes in the rock mass and load explosives into the blast holes for blasting.

[0003] However, in the prior art, when deep hole blasting is performed, water often accumulates in the deep hole. In order to ensure that the blasting device enters the water, a counterweight is provided on the blasting device. However, this will cause the blasting device to sink directly to the bottom and be easily covered by other objects in the deep hole, thus affecting the blasting effect. Therefore, we propose a deep hole blasting device. Utility Model Content

[0005] The utility model solves the above-mentioned technical problems with the following solution: a deep hole blasting device, comprising a bottom block, a charging cartridge threadedly mounted on the upper end surface of the bottom block, the charging cartridge filled with explosives, a sealing cap threadedly mounted on the upper end of the charging cartridge, a detonator buried in the explosive, the detonator connected to a detonating cord movably penetrating the sealing cap, a connecting ring threadedly mounted on the outer wall of the bottom block, a plurality of L-shaped first support rods fixedly mounted on the outer wall of the connecting ring, the lower end of the first support rod being hollowly arranged, a second support rod movably embedded in the lower end of the first support rod, a plurality of the second support rods being fixedly connected by a cross-shaped connecting plate, a counterweight block fixedly mounted on the upper end surface of the connecting plate, and the counterweight block being connected to an adjustment mechanism.

[0006] Preferably, the adjustment mechanism includes a screw rod rotatably mounted on the upper end surface of the counterweight block, a plurality of the first support rods are fixedly connected by a cross-shaped fixing piece, the screw rod thread passes through the fixing piece, and a knob is fixedly mounted on the upper end of the screw rod.

[0007] Preferably, a traction wire is fixedly mounted on the upper end surface of the cover.

[0008] Preferably, a limiting ring is provided on the upper end surface of the connecting ring, and the limiting ring is fixedly mounted on the outer wall of the bottom block.

[0009] Preferably, the inner wall of the drug cartridge is provided with a waterproof layer.

[0010] The beneficial effects of the utility model are:

[0011] By arranging a first support rod to cooperate with a second support rod, the cartridge can be prevented from sinking directly to the bottom. At the same time, the second support rod is slidably connected to the first support rod, and the rotating screw can adjust the relative distance between the first support rod and the second support rod, thereby adjusting the height of the cartridge to meet different blasting requirements. A counterweight block is set on the connecting plate to ensure the stable sinking of the device. At the same time, the first support rod is installed on the connecting ring, and the connecting ring is threadedly connected to the bottom block. The lower components such as the connecting ring and the first support rod can be directly disassembled when needed, which is more functional.

[0021] like Figure 1-3 As shown, the utility model is a deep hole blasting device, including a bottom block 1, the bottom block 1 has a certain quality, and ensures that the loading cartridge 2 can sink into the water when the lower components such as the connecting ring 7 are disassembled, the upper end surface of the bottom block 1 is threadedly installed with a loading cartridge 2, and the inner wall of the loading cartridge 2 is provided with a waterproof layer 16, and the waterproof layer 16 is provided to prevent the explosive from getting wet, and the loading cartridge 2 is filled with explosives 3, and the upper end of the loading cartridge 2 is threadedly installed with a sealing cover 4, and the upper end surface of the sealing cover 4 is fixedly installed with a traction line 14, a detonator 5 is buried in the explosive 3, and the detonator 5 is connected to a detonating cord 6 that movably penetrates the sealing cover 4, and the outer side wall of the bottom block 1 is threadedly installed with a connecting ring 7, and the upper end surface of the connecting ring 7 is provided with a limiting ring 15, and the limiting ring 15 is fixedly installed on the outer wall of the bottom block 1. The ring 15 is used to limit the connecting ring 7 to ensure the stable connection between the connecting ring 7 and the bottom block 1. A plurality of L-shaped first support rods 8 are fixedly installed on the outer wall of the connecting ring 7. The lower end of the first support rod 8 is hollow, and a second support rod 9 is movably embedded in the lower end of the first support rod 8.
