DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Refer to Figures 1-5, The explosive shaped charge initiation charging device includes a charging cylinder 1. An explosive accommodating cavity is provided inside the charging cylinder 1. A cylinder cover 2 is sleeved on the outer side of the top of the charging cylinder 1, and the charging cylinder 1 and the cylinder cover 2 are connected by a buckle. A fixing plate 3 is integrally formed on the top of the cylinder cover 2. A guiding column 4 movably connected thereto penetrates through the center of the fixing plate 3. A positioning block 5 is integrally formed at one end of the guiding column 4 away from the fixing plate 3. A pair of symmetric first springs 6 are welded between the fixing plate 3 and the positioning block 5. A pull ring 7 penetrates through the center of the top of the fixing plate 3 and the guiding column 4. It limits the guiding column 4 and the positioning block 5 through the pull ring 7. When the pull ring 7 is pulled out, the positioning block 5 is driven by the elastic force of the first spring 6 itself to move towards the side away from the fixing plate 3, so that the positioning block 5 squeezes the inner wall of the blast hole, thereby limiting and fixing the position of the charging cylinder 1. Then the shaped charge surface can be positioned, thus achieving the purpose of making the shaped charge surface close to the blasting body.

[0020] A fixing ring 8 is welded in the middle of the top of the charging cylinder 1. The fixing ring 8 is a semi-circular ring. An installation cylinder 9 is welded on the top of the charging cylinder 1. A moving rod 10 movably connected thereto penetrates through one end of the installation cylinder 9. The moving rod 10 is composed of a cylinder and a disc. A second spring 11 is installed inside the installation cylinder 9, and one end of the second spring 11 is welded to the disc at one end of the moving rod 10. A limiting ring 12 is welded to the end of the moving rod 10 away from the second spring 11. By pulling the moving rod 10 to squeeze the second spring 11 and then inserting the detonating cord, and then releasing the moving rod 10, the moving rod 10 and the limiting ring 12 are driven by the second spring 11 to squeeze and fix the inserted detonating cord.

[0021] A plurality of connecting rods 13 are fixedly arranged in a circular array inside the charging cylinder 1, and an installation ring 14 is fixed between the plurality of connecting rods 13. The inserted detonating cord can be limited through the installation ring 14.

[0022] Explosive introduction holes 15 are penetrated through the tops of both the charging cylinder 1 and the cylinder cover 2. Through the explosive introduction holes 15, it is convenient to pour the colloidal explosive into the inside of the charging cylinder 1. A sealing cover 16 is installed inside the explosive introduction hole 15 penetrated through the top of the cylinder cover 2, and the sealing cover 16 can seal the explosive introduction hole 15. Installation holes 17 are penetrated through the centers of the tops of both the charging cylinder 1 and the cylinder cover 2, which is convenient to insert the detonating cord into the inside of the charging cylinder 1.

[0023] When this device is in use, open the cylinder cover 2, squeeze the second spring 11 by pulling the moving rod 10, insert the detonating fuse into the installation hole 17. When the detonating fuse is inserted to the specified length, introduce the detonating fuse into the guiding and installing ring 14. At this time, release the moving rod 10, and drive the moving rod 10 and the limiting ring 12 by the second spring 11 to squeeze and fix the inserted detonating fuse. Then cover the cylinder cover 2, open the sealing cover 16, squeeze the colloidal explosive into the charging cylinder 1 through the explosive inlet hole 15. After the colloidal explosive is filled, close the sealing cover 16, install the charging cylinder 1 on the inner wall of the blast hole. The outer shape of the charging cylinder 1 is adapted to the shape of the blast hole. At this time, pull out the pull ring 7, and drive the positioning block 5 to move away from the fixed plate 3 by the elastic force of the first spring 6 itself, so that the positioning block 5 generates a force action with the inner wall of the blast hole for fixation.
