[0002] Explosives refer to a chemical substance that can produce explosions. They are mostly used in industrial fields such as mineral mining, building demolition, road construction, and dam construction. They are an efficient tool. Due to the dangerousness of blasting explosives themselves, specific tools and equipment are required to handle them, such as anti-static clothing, explosion-proof warehouses, and cannon barrels.

[0003] According to the patent number CN217058538U, a deep hole step blasting explosive centering limiting device is disclosed, which includes a charge cartridge with a top opening, an explosive roll supporting and limiting structure is arranged inside the charge cartridge, and a plurality of support blocks arranged at intervals along its circumference are fixedly arranged on the outer wall of the charge cartridge, a threaded hole is arranged on a side of the support block away from the center of the charge cartridge, and a positioning screw is connected through the threaded hole.

[0004] During the implementation of the above scheme, radial uncoupled charging can be achieved in blastholes of different diameters. However, during the implementation of the above scheme, it is difficult to always keep the explosive roll at the center of the blasthole. When the explosive roll is placed in the blasthole, if it deviates from the center position, it is easy to be rubbed by the retaining wall, thereby affecting the quality of blasting and even causing the explosive roll to explode prematurely, seriously damaging the blasting effect. For this reason, we provide a blasting explosive centering device to solve the above problem. Utility Model Content

[0026] The embodiment of the utility model provides a blasting explosive centering device, which can clamp the explosive roll so that the explosive roll is always located at the center of the blast hole, solving the problem that it is difficult to always locate the explosive roll at the center of the blast hole in the above-mentioned technology.

[0027] See also Figure 1 and Figure 2 Three clamping mechanisms 2 are arranged above the clamping seat 1. The three clamping mechanisms 2 are distributed in a triangle, which can clamp the explosive roll more stably, prevent the explosive roll from changing position due to friction with the retained wall during the process of being placed into the blast hole, and ensure that the explosive roll is always located in the center of the device.

[0028] The bottom surface of the clamping seat 1 is fixedly connected with a lower fixing plate 3, and the top surface of the lower fixing plate 3 is fixedly connected with a protection plate 4 corresponding to the clamping mechanism 2. Each protection plate 4 is located outside the clamping mechanism 2 and can protect the clamping mechanism 2.

[0029] See also Figure 4 The outer surface of each protective plate 4 is fixedly connected with a telescopic spring 5, and one end of each telescopic spring 5 is fixedly connected with a connecting plate 6. Through the setting of the telescopic spring 5, the clamping plate 205 can be squeezed to provide greater support for the clamping plate 205 to clamp the explosive roll, thereby improving the clamping effect of the device.

[0030] The outer surface of each connecting plate 6 is fixedly connected with an auxiliary plate 7, and each auxiliary plate 7 is adapted to the clamping plate 205. The auxiliary plate 7 is made of rubber, which can support the clamping plate 205 while increasing the friction with the clamping plate 205, so that the clamping plate 205 can better clamp the explosive roll.

[0031] The outer surface of each protective plate 4 is provided with a bolt hole 8, the interior of each bolt hole 8 is threadedly connected with a threaded rod 9, one end of each threaded rod 9 is fixedly connected with a wall contact plate 10, and the threaded rod 9 and the wall contact plate 10 can be selectively installed according to the size of the blast hole. If the blast hole is large, the diameter of the device can be increased by adjusting the threaded rod 9, so that the device can be better located in the center of the blast hole.

[0032] Please refer again Figure 1 and Figure 2 An upper fixing plate 11 is arranged above the lower fixing plate 3, and each protective plate 4 is fixedly connected to the upper fixing plate 11. Through the arrangement of the lower fixing plate 3 and the upper fixing plate 11, the explosive roll can be prevented from rubbing against the retaining wall during the process of being dropped into the blast hole, thereby increasing the stability and safety of the device.

[0033] See also Figure 3 The clamping mechanism 2 includes a slide groove 201 opened on the surface of the clamping seat 1, the inner wall of the slide groove 201 is fixedly connected with a slide rod 202, and the outer surface of the slide rod 202 is slidably connected with a slider 203. Through the setting of the slide rod 202, support and limit are provided for the sliding of the slider 203 to prevent the slider 203 from shaking during the sliding process, which affects the clamping effect of the device on the explosive roll.

[0034] The slider 203 is slidably connected to the slide groove 201, and the top surface of the slider 203 is fixedly connected to a connecting rod 204, and the top of the connecting rod 204 is fixedly connected to a clamping plate 205. The material of the clamping plate 205 is bamboo strips, and the top of the clamping plate 205 is a smooth inclined surface, which is convenient for the staff to place the explosive roll inside the clamping plate 205.

[0035] A return spring 206 is sleeved on the outer surface of the slide bar 202, and the two ends of the return spring 206 are fixedly connected to the slide groove 201 and the slider 203 respectively. Through the setting of the return spring 206, after the explosive roll is placed, the clamping plate 205 can be pushed to reset, thereby automatically clamping the explosive roll and giving the clamping plate 205 a thrust. Under the simultaneous push of the three clamping plates 205, the explosive roll can always be located in the center of the device.

[0036] Working principle: the staff first adjusts the threaded rod 9 according to the size of the blast hole so that the diameter of the device is slightly smaller than the diameter of the blast hole, and then holds the explosive roll and gently squeezes the clamping plate 205. At this time, the clamping plate 205 will push the slider 203 to slide, thereby facilitating the placement of the explosive roll. After the placement is completed, the reset spring 206 pushes the slider 203 to reset under the action of elastic force, thereby giving the clamping plate 205 a thrust to keep the clamping plate 205 clamping the explosive roll. While the clamping plate 205 clamps the explosive roll, it will squeeze the auxiliary plate 7. At this time, the auxiliary plate 7 will also give the clamping plate 205 a thrust to ensure the clamping effect of the clamping plate 205 on the explosive roll. Finally, under the clamping effect of the three clamping plates 205, the explosive roll can always be located in the center of the device, thereby avoiding touching the retained wall and enhancing the blasting effect of the explosive.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
