Description

Technical Field

[0001] The utility model relates to the technical field of concentrated energy blasting, in particular to a concentrated energy blasting charging device used in a high and large mining area. Background Art

[0002] The shaped charge blasting device is a device used for rock blasting. It can achieve efficient crushing of hard rock by accurately controlling the explosion direction and energy concentration of the explosive. This device usually includes positioning tubes, directional tubes, shaped charge packs, and angle reference marks, which work together to ensure the accuracy and effectiveness of blasting.

[0003] In the prior art, when charging an integrated energy-gathering device, explosives are generally stuffed into the interior manually. The charging process is time-consuming, labor-intensive, and inefficient. However, for a detachable energy-gathering device, the overall strength decreases due to changes in its structure. During the blasting process, its joints are prone to break first, resulting in a decrease in the energy-gathering blasting effect. Utility Model Content

[0006] Preferably, a spring cavity is opened in the inner wall of the clamping groove, a compression spring is fixedly connected to the inner wall of the spring cavity, and a T-shaped clamping block is fixedly connected to the other end of the compression spring.

[0007] Preferably, the reinforcing fixing mechanism comprises a reinforcing sleeve, a fixing groove is formed on the reinforcing sleeve, a fixing block is arranged at the lower end of the reinforcing sleeve, a connecting block is fixedly connected to the side wall of the fixing block, and a limiting block is fixedly connected to the side wall of the connecting block.

[0008] Preferably, the spring cavity is connected with the snap-in groove through the cavity opening, the bottom of the T-shaped snap-in block is against the side wall of the spring cavity, the side wall of the T-shaped snap-in block is slidably connected to the inner wall of the cavity opening, the T-shaped snap-in block is snap-fitted with the limiting groove, and the outer end of the T-shaped snap-in block is set as a circular surface.

[0009] Preferably, the limiting block is engaged with the fixing groove, and the connecting block has toughness.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. Put the explosive into the first fixed tube, rotate the second fixed tube so that the connecting plate is inserted into the clamping groove. When the connecting plate is inserted into the clamping groove, the connecting plate squeezes the T-shaped clamping block, and the T-shaped clamping block squeezes the squeezing spring, so that the T-shaped clamping block returns to the spring cavity. When the connecting plate abuts against the innermost side of the clamping groove, the squeezing spring squeezes the T-shaped clamping block so that the T-shaped clamping block pops out and abuts against the inner wall of the limiting groove. The first fixed tube and the second fixed tube are clamped by the T-shaped clamping block and the limiting groove, so that the explosive is fixed in the device, which is convenient for charging the device, saves time and effort, and improves the charging efficiency.

[0012] 2. By engaging the reinforcing sleeve at the connection between the first fixed tube and the second fixed tube, removing the connecting block, engaging the limit block on the inner wall of the fixing groove, and because the connecting block has toughness, loosening the connecting block, resetting the connecting block, squeezing the reinforcing sleeve, and squeezing the reinforcing sleeve directly between the first fixed tube and the second fixed tube through the fixing block, the overall strength of the structure of the device during blasting is improved, the connection is prevented from breaking first, and the energy-gathering blasting effect is improved.
