Abstract
The utility model provides a detonating cord fixing clip, wherein a fixing groove is arranged on the clip body; fixing pin(s) is/are arranged on one side or two sides of the fixing groove; the fixing groove is matched with the detonating cord; and the clip bodies are positioned on the two sides of a joint of the detonating cord and the detonating tube. The detonating cord fixing clip provided by the utility model can be used for fixing the detonating cord, thereby transmitting detonation waves smoothly and reducing blind shots greatly. When the detonating cord fixing clip is not used, the occurrence probability of blind shots of different degrees is not less than 80% no matter a middle deep hole step explosion or an ore yard explosion is adopted; after the detonating cord fixing clip provided by the utility model is adopted, the amount of blast holes for the first time is 30, 64 fixing clips are used, and no blind shot exists after the explosion; and the total success rate is higher than 99.5% after the fixing clips are used repeatedly.
Description
Technical field
The utility model relates to the mine blasting field, particularly a kind of primacord fixed card.
Background technology
Primacord is main initiating equipment in the surface mine blasting network, generally adopts it to transmit detonation wave, but the normal blind big gun of generation that is prone to needs explosion again, and time-consuming, cost also rises.
Summary of the invention
The utility model technical problem to be solved provides a kind of primacord fixed card, can avoid the swing of primacord in the propagation of explosion process, reduces the generation of blind big gun.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of primacord fixed card, and the card body is provided with holddown groove, and the holddown groove one or both sides are provided with steady pin.
Described holddown groove cooperates with primacord.
Described card body is positioned at the both sides of primacord and detonator junction.
Described card body also is positioned at a side of afterbody and the primacord and the detonating capsule connecting portion of primacord.
Through anatomizing, the reason that blind big gun produces is that traditional primacord produces strong swing in the process of propagation of explosion, thereby the detonator that is attached thereto is given a discount, and the detonation wave transmission is interrupted, thereby has produced blind big gun.
A kind of primacord fixed card that the utility model provides, fixedly primacord makes it transmit detonation wave smoothly, significantly reduces blind big gun and produces.When not using the utility model, no matter be, all have blind big gun in various degree to occur in medium-length hole bench blasting or ore yard explosion; Occurrence probability totally is higher than 80%, behind employing the utility model, 30 in big gun hole is arranged for the first time; Use 64 fixed card, do not occurred blind big gun after the explosion.Repeatedly use later on, its total success rate is more than 99.5%.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the front view of the utility model.
Fig. 2 is that the A of the utility model is to view.
Fig. 3 is the overall structure sketch map of the utility model.
The specific embodiment
In Fig. 1, Fig. 2, a kind of primacord fixed card, card body 1 is provided with holddown groove 2, and holddown groove 2 one or both sides are provided with steady pin 3.
Described holddown groove 2 cooperates with primacord 4.According to the primacord external diameter is 6mm, and the internal diameter of holddown groove 2 is identical with the external diameter of primacord 4.
In Fig. 3, described card body 1 is positioned at the both sides of primacord 4 and detonator 6 junctions.Be the both sides that primacord 4 and detonator 6 adopt adhesive plaster 5 junctions, during use steady pin 3 squeezed in rock or the earth that holddown groove 2 blocks primacord 4 and gets final product.
Described card body 1 also is positioned at a side of afterbody and the primacord 4 and detonating capsule 7 connecting portions of primacord 4.After adopting the utility model, the generation of blind big gun significantly reduces.
