Description

Technical Field

[0001] The invention relates to the technical field of blasting, in particular to a blasting shaped charge structure and a charging method thereof. Background Art

[0002] Blasting is a technology that uses the compression, loosening, destruction, throwing and killing effects of explosives in the air, water, soil and rock media or objects to achieve the desired purpose. In blasting engineering, concentrated charge blasting is a directional blasting technology. Its principle is to use the hole at one end of the explosive bag to enhance the effect of local destruction, which is called the concentrated charge effect. Usually, the hole used for blasting is usually a wedge-shaped concentrated charge groove.

[0003] For example, a Chinese patent document with the announcement number CN209512669U discloses a simple and quick shaped charge device. The simple and quick shaped charge device includes a main body and a cover plate, the main body and the cover plate are relatively arranged together to form a hollow column, the size ratio of the main body and the cover plate is greater than 2:1, an undercut groove is provided at the buckling end of the main body, and an undercut hook is provided at the buckling end of the cover plate, or an undercut hook is provided at the buckling end of the main body, and an undercut groove is provided at the buckling end of the cover plate, the undercut hook or the undercut groove cooperates, and the main body and the cover plate are connected or plugged together by means of the undercut groove and the undercut hook. The simple and quick shaped charge device has a low risk factor, is not easy to damage, and has a long service life.

[0004] The technical solution provided by the above patent and the shaped charge structure in the related prior art all have the following problems: the shaped grooves of the charge structure are symmetrically arranged on both sides of the charge structure, and after the explosive inside the charge structure explodes, a jet is formed along the direction of the bisector of the angular bisector of the shaped grooves, and the jet hits the inner wall of the blast hole, so that the inner wall of the blast hole and even the entire object to be blasted can be directionally cut. However, in this process, since the two shaped grooves share a portion of explosives, when there is a difference in the structural strength of the object to be blasted on the inner wall of the blast hole, for example, the structural strength of the object to be blasted close to one of the shaped grooves is low, and the structural strength of the object to be blasted close to the other shaped groove is high, or The structural strength of the material to be blasted near the bottom of the blasthole is high, and the structural strength of the material to be blasted near the top of the blasthole is low. In this way, the part with low structural strength is easily cut quickly by the jet generated by the explosion, while the part with high structural strength is not easy to be cut. In this way, the cracks produced after the part with low structural strength is cut will cause most of the high-pressure gas generated by the explosion to be discharged along the cracks, and finally it is easy for the cutting depth of the part with high structural strength to be small, which cannot meet the purpose of actual blasting needs; in addition, the angle between the bisectors of the two energy-gathering grooves cannot be flexibly adjusted, which limits the scope of application of the charging structure.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-Figure 10 , the present invention provides a technical solution:

[0054] A blasting shaped charge structure includes a plurality of charge tanks 1 and an adjustment disk 2. In this embodiment, the number of charge tanks 1 is not specifically limited, and can be adaptively adjusted according to factors such as the actual depth of the blast hole to meet the needs of blasting. Specifically, a plurality of charge tanks 1 are coaxially arranged to form a cylindrical explosive package, so as to be placed inside the blast hole; moreover, the charge tank 1 is in a hollow cylindrical shape, and a shaped energy groove 14 is arranged on its outer circumference. The shaped energy groove 14 in this embodiment is wedge-shaped.

[0055] The adjusting disk 2 is used to adjust the angle between the angular bisectors of the energy-gathering grooves 14 on each two adjacent charge tanks 1, wherein the angular bisector of the energy-gathering grooves 14 refers to the angular bisector of the energy-gathering grooves 14 in the top view. Normally, the angle between the angular bisectors of the energy-gathering grooves 14 on two adjacent charge tanks 1 is 180°. However, under some special blasting requirements, the user can adjust the angle between the angular bisectors of the energy-gathering grooves 14 on two adjacent charge tanks 1 by rotating according to actual needs. For example, the angle can be adjusted to 150° or 130°, etc., so that the explosives inside the charge tank 1 can be exploded through the energy-gathering grooves. The angle of the jet ejected from the groove 14 enables one explosive pack to complete a non-180° cutting of the explosive material. Furthermore, since each charge tank 1 is provided with a corresponding energy focusing groove 14, the explosive inside the charge tank 1 will form a jet at the corresponding energy focusing groove 14 after the explosion, so that the inner wall of the blast hole opposite to the energy focusing groove 14 can be blasted and cut, and there will be no situation where one charge tank 1 corresponds to two energy focusing grooves 14 to form two jets. That is, while ensuring the bidirectional cutting capability of the cylindrical explosive pack, it is ensured that the cutting depth of the jet formed at each energy focusing groove 14 meets the actual blasting requirements.

[0056] The adjusting disk 2 includes a top disk 21, a bottom disk 22 and a locking component. The top disk 21 is coaxially fixed on the top surface of the medicine tank 1, and the bottom disk 22 is coaxially fixed on the bottom surface of the medicine tank 1. The bottom disk 22 at the bottom of one medicine tank 1 is detachably rotatably connected to the top disk 21 at the top of another medicine tank 1 adjacent thereto. The locking component is used to limit the relative position between the rotatably connected top disk 21 and bottom disk 22. The bottom disk 22 of one medicine tank 1 can be plugged and connected to the top disk 21 of another medicine tank 1 adjacent thereto, so as to form an adjusting disk 2 between the two adjacent medicine tanks 1, thereby realizing the coaxial rotation connection between the two adjacent medicine tanks 1, and being used to manually adjust the relative angular position of the two adjacent medicine tanks 1, and locking the adjusting disk 2 with the locking component after the adjustment is completed. Moreover, the diameters of the top disk 21 and the bottom disk 22 are equal to the diameter of the medicine tank 1. The purpose of such a setting is to use the top disk 21 and the bottom disk 22 to block the upper and lower ends of the energy collecting groove 14. The medicine-filling tank 1 and the regulating disk 2 (except the spring 224 described below) in this embodiment can be made of PVC material.

[0057] In actual use, multiple charge tanks 1 are coaxially connected using the adjustment disk 2, and then the angular position of the charge tank 1 is adjusted according to the actual blasting requirements, so that the angle between the angular bisectors of the energy focusing grooves 14 on two adjacent charge tanks 1 meets the actual blasting requirements, and then locked using the locking component. After that, the explosive package consisting of multiple charge tanks 1 can be placed in the blast hole and then ignited for blasting.

[0058] By setting up multiple charging tanks 1, the traditional continuous charging mode is changed to the separate charging mode of the present invention, and each charging tank 1 is only corresponding to one energy focusing groove 14, so that after the explosion of the explosives in each charging tank 1, only a separate jet can be formed by the corresponding energy focusing groove 14 to cut the explosive material, which has good directivity and reduces the waste of detonation wave energy; at the same time, through the setting of the adjustment disk 2, the angle between the angular bisectors of the energy focusing grooves 14 on two adjacent charging tanks 1 can be flexibly adjusted, and the angle between the angular bisectors of the two adjacent energy focusing grooves 14 corresponds to the angle of the jets generated by the two energy focusing grooves 14, that is, the adjustment of the blasting cutting angle is realized, which meets various blasting needs and has a wide range of applications.

[0059] In this embodiment, the locking component includes a threaded hole 214 formed on the top plate 21 and a positioning stud 215 threadedly connected to the threaded hole 214; the axial direction of the positioning stud 215 is parallel to the axial direction of the medicine tank 1, the threaded hole 214 passes through the top plate 21, and the bottom end of the threaded hole 214 is connected to the energy gathering groove 14;

[0060] In this embodiment, a hexagonal groove 2153 is provided on the bottom surface of the positioning stud 215. Of course, in other embodiments, a cross groove or the like can be used instead of the hexagonal groove 2153. The function of the hexagonal groove 2153 is to use a corresponding hexagonal screwdriver to screw the positioning stud 215 so that the top end of the positioning stud 215 can squeeze the chassis 22, thereby achieving locking between the adjacent top plate 21 and the chassis 22, and ensuring that the angle between the angular bisectors of the two adjacent energy gathering grooves 14 no longer changes.

[0061] The charge tank 1 in this embodiment comprises a cylinder 11, a top sealing plate 12 and a bottom sealing plate 13; an energy-gathering groove 14 is arranged on the peripheral wall of the cylinder 11; the top sealing plate 12 and the bottom sealing plate 13 are respectively sealed and fixed at the upper and lower ends of the cylinder 11.

[0065] Furthermore, a slide groove 2221 extending along its radial direction is provided on the circumferential surface of the circular block 222, and the slide groove 2221 and the slider 223 are matched with each other so that the slider 223 can only slide along the extension direction of the slide groove 2221; the chassis 22 also includes a spring 224, the spring 224 is arranged inside the slide groove 2221, and the two ends of the spring 224 are respectively fixedly connected to the inner surface of the slide groove 2221 and one end of the slider 223, so that the spring 224 can be used to realize the elastic sliding of the slider 223; the bottom of the other end of the slider 223 is provided with an inclined surface 2231, when the slider 223 is in the overhanging position, the lower end of the inclined surface 2231 is inside the slide groove 2221, so that the slider 223 can be pressed and inserted into the inside of the second through hole 212.

[0066] In order to improve the accuracy of adjusting the angle between the angular bisectors of the energy focusing groove 14, angle scale lines 213 are provided on the circumferential surface of the top plate 21; positioning scale lines 225 are provided on the circumferential surface of the bottom plate 22. When adjusting, the position of the angle scale line 213 pointed by the positioning scale line 225 can be used to determine whether the adjustment is in place.

[0067] Furthermore, the outer side of the medicine tank 1 in this embodiment is wrapped with a jacket 3; the jacket 3 can be made of metal material.

[0068] The jacket 3 includes a first guide frame 31 and a second guide frame 32 symmetrically arranged on both sides of the medicine tank 1 and a connecting piece 33 fixedly connected between the first guide frame 31 and the second guide frame 32 . The first guide frame 31 is aligned with and connected to the notch of the energy gathering groove 14 .

[0069] In this embodiment, the jacket 3 also includes a first blocking plate 34 and a second blocking plate 35; the first blocking plate 34 and the second blocking plate 35 are respectively fixed to the upper and lower sides of one end of the first guide frame 31 close to the energy gathering groove 14, and the first blocking plate 34 and the second blocking plate 35 have the same cross-sectional shape as the energy gathering groove 14; a positioning hole 341 coaxial with the threaded hole 214 is provided on the first blocking plate 34, and the positioning stud 215 includes a coaxial and fixedly connected screw 2151 and a positioning rod 2152, the positioning rod 2152 extends to the interior of the positioning hole 341, and a hexagonal groove 2153 is provided on the bottom surface of the positioning rod 2152.

Specifically, when installing the top plate 21 During the process, it is only necessary to insert the positioning rod 2152 into the interior of the positioning hole 341 to complete the positioning of the top plate 21, and there is no need to adjust the angular position of the top plate 21 by rotating the top plate 21; the upper surface of the first sealing plate 34 is in contact with the lower surface of the top plate 21, and the lower surface of the second sealing plate 35 is in contact with the upper surface of the bottom plate 22. The first sealing plate 34 and the second sealing plate 35 are used to improve the sealing strength of the upper and lower ends of the energy focusing groove 14, so that the jet formed by the energy focusing groove 14 can fully impact the inner wall of the blast hole, and the cutting effect is better. Moreover, the first guide frame 31 also has the function of preventing the jet formed by the energy focusing groove 14 from scattering. At the same time, the first guide frame 31 and the second guide frame 32 also have the function of centering, so that the cylindrical explosive package composed of multiple charge tanks 1 can be coaxial with the blast hole, so that the explosive package remains stable during the blasting process.
