Abstract
The utility model discloses a detonating tool with reliable propagation of detonation. The detonating tool comprises a casing; a main charge is loaded in the casing; a lead hole is arranged in the middle part of the inner cavity of the casing; two blasting cap holes are further arranged in the inner cavity of the casing; the bottom of the blasting cap holes is connected with a priming explosive; the detonating mode of exciting the main charge by a blasting cap in the prior art is changed to the detonating mode that the blasting cap excites the priming explosive and then the priming explosive excites the main charge; the top of the casing is provided with an energy collecting hole; and the energy collecting hole is of a tapered structure, a spherical structure or a cylindrical structure. The detonating tool with reliable propagation of detonation disclosed by the utility model is mainly used for detonating various insensitive explosives or boosting detonating blast waves, so that the main charge can be quickly and stably detonated; and the detonating tool has the characteristics of high density, high strength, good water-resisting property, safety and zero pollution, and is fit for the reliable detonation of various insensitive explosives in various climatic conditions.
Description
Technical field
The utility model relates to the explosion utensil, specifically is a kind of initiating source that is used for mine blasting, engineering explosion, water borehole blasting and large outdoors colliery explosion.
Background technology
At present, usually the detonation tool structure by: housing, main charge two parts are formed, and product has a detonator hole and a wire guide; Excite main charge through the detonator in the detonator hole when exciting; Reach the whole blast of detonation tool, thereby ignite desensitized explosive, make it reach steady detonation very soon.
Because the detonation tool product requirement has characteristics such as sensitivity to initiation height, explosion velocity is high, degree of packing is high, power is big; Therefore the main charge of detonation tool product all is to mix with two kinds of high explosives; And main charge itself will have cap-sensitivity, causes product cost very high.
Summary of the invention
The purpose of the utility model provides the reliable economical detonation tool of a kind of propagation of explosion.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
The reliable detonation tool of a kind of propagation of explosion comprises housing, and main charge is housed in the housing, and housing inner chamber middle part is provided with wire guide, and the housing inner chamber also is provided with two detonator holes, and bottom, detonator hole is connected with primary explosive column.
The utility model has changed in the prior art and excites primary explosive column to excite detonating of main charge by primary explosive column again by becoming the pattern that detonator excites main charge, changing by detonator.Because primary explosive column is manufactured by single high explosive and formed, sensitivity is very high, can improve the product percentage of initiation after the use, guarantee blasting quality; Realized that simultaneously exciting primary explosive column to become double detonator by single detonator excites primary explosive column, is excited the detonation mode of main charge again by primary explosive column.Double detonator detonate architecture advances the probability that can not normally act on because of detonator cause the disadvantage that main charge can not reliable initiation, can also obviously reduce the bursting work cost.
The housing top is provided with sockets for collecting energy; The moment excitation energy of detonation tool product is greatly improved; Play positive role to igniting desensitized explosive; Not only reach good propagation of explosion, ignition effect, and effectively raise relevant blast parameter such as product power, can also reduce product cost through adjustment to product main charge prescription.
Compared with prior art; The utility model has realized that propagation of explosion structure and cumulative structure are in the inner application of detonation tool; And product structure is simple, reasonable in design, explosion transfer performance is good, and percentage of initiation, the moment excitation energy that effectively raises product is greatly improved.Thereby relevant blast parameter such as power is effectively improved, better improve the detonation propagation reliability of nonel tube of product, can under the prerequisite that does not reduce its product main performance index, reduce product cost through adjustment to product main charge prescription.
The described detonation tool of the utility model is mainly used in detonate all kinds of desensitized explosives or the enhancing shock wave that detonates, and makes main charge reach steady detonation very soon.It has high density, high-power, good, safe, the free of contamination characteristics of water-resistance, is applicable to the reliable initiation of all kinds of desensitized explosives under the various weather conditions.

The specific embodiment
Requiring the technical scheme of protection to do below in conjunction with accompanying drawing to the utility model specifies.
The reliable detonation tool of a kind of propagation of explosion that the utility model is described comprises housing 1, and main charge 2 is housed in the housing 1, and housing 1 inner chamber middle part is provided with wire guide 3, and housing 1 inner chamber also is provided with two detonator holes 4, and 4 bottoms, detonator hole are connected with primary explosive column 5.
Housing 1 usefulness paper or plastics are processed, and main charge 2 is composite explosives.Two booster gains 5 are formed detonation train, and the weight of each primary explosive column is 8～30g, and the employing passivation is pacified very much or the desensitized hexogen compacting forms.
The utility model adopts the double detonator structure, and detonator hole 4 be two blind holes of dark 60～100mm, gos deep into primary explosive column 5 inside bottom the blind hole, helps fully contacting of detonator and primary explosive column 5 in the initiation process, has improved the percentage of initiation and the detonation propagation reliability of nonel tube of product.Wire guide 3 is a through hole, and two detonators pass two detonator holes 4 of fixing insertion, wire guide 3 backs respectively, when any one detonator normally acts on, can reach 100% propagation of explosion.
Housing 1 top is provided with sockets for collecting energy 6, and its big I of sockets for collecting energy 6 structures can play the effect of energy accumulating according to the diameter decision of product in the initiation process of product.
Described sockets for collecting energy 6 is pyramidal structure, spherical structure or cylindrical structural.The type of selecting for use of sockets for collecting energy 6 can be according to the decision of characteristics such as the geology of customer requirements or explosion type and bursting work, landform, and the size of sockets for collecting energy is according to the decisions such as appearance and size of product.
