Abstract
The utility model relates to a device that in -process nonel detonator dropped is clogged in prevention big gun hole, does it include first steel pole (1 1 ), the second steel pole (1 2 )And through -hole (2), its characterized in that: first steel pole (1 1 )With second steel pole (1 2 )Two steel cylinders of diameter and length homogeneous phase etc. Connect through the welding mode between them, the radius of through -hole (2) is less than first steel pole (1 1 ), the second steel pole (1 2 )The radius, and only be located first steel pole (1 1 )One side. The utility model discloses stopped in the surface blasting engineering when the big gun hole clogging the process the drop possibility in big gun hole of detonator accident that nonel detonator is used for passing the section of exploding, solved because of the unneccessary trouble that the biography section of exploding detonator accident dropped and brings, guaranteed the success rate of big gun hole blasting to have improved work quality and efficiency.
Description
Technical field
This utility model relates to the guard technology field of blasting engineering, the device that during a kind of prevention blast hole stemming conveniently, safely, Nonel detonator drops.
Background technology
In engineering explosion, non-electric nonel tube detonator is one of critical elements in non-electric initiation network system, it has a water resisting property, do not affected by stray electrical current, cheap, the outstanding advantages such as strong adaptability and safety height, thus be widely used in all kinds of engineering explosions, advantage the most incomparable in mine blasting the most in the open.nullAt present during mine blasting blast hole stemming，Detonator for propagation of explosion section in filling and couples before blasting circuit the most exposed，This partly plastic detonator is frequently used the bulk stone at scene and is wound constraint，And then fix it，But in actual mechanical process，Because near on-the-spot big gun hole, bulk stone is less，Even without，Part dynamiter may use lighter in weight、The stone that profile is less carries out simple bondage，The most fearful is，Few part workmen because not carrying out the fixing operation of any propagation of explosion detonator without stone，Later stage filling is caused to cause propagation of explosion detonator to come off because stone is small and light during waiting，Finally drop big gun hole，This brings trouble greatly to construction，Clear up it，Can take considerable time and manpower，And there is certain potential safety hazard，Delay the construction period，Affect blast working efficiency and quality.
Utility model content
The problem existing during engineering explosion is clogged for solving non-electric nonel tube detonator, this utility model provides a kind of device that Nonel detonator drops during preventing blast hole stemming.
For solving above-mentioned drawback, technical solution adopted in the utility model is: a kind of device that Nonel detonator drops during preventing blast hole stemming, and it includes the first steel pole (1-1), the second steel pole (1-2) and through hole (2).It is characterized in that: described first steel pole (1-1) and the second steel pole (1-2) are two steel cylinder of diameter and identical length etc., are attached by welding manner between them；The radius of described through hole (2) is less than described first steel pole (1-1), the radius of the second steel pole (1-2), and is only located at the side of the first steel pole (1-1).
Preferably, the length of described first steel pole (1-1) and the second steel pole (1-2) is all higher than 290mm, and diameter is all higher than 30mm.
Preferably, the position of described through hole (2) is at distance the first steel pole (1-1) end points 70mm, and radius is 5mm.
The beneficial effects of the utility model are: mine is on-the-spot in the open, and workmen, without earnestly seeking searching bulk stone, only needs directly on device welding center, the detonator being used for propagation of explosion part to be wound around a few, can realize detonator and fixedly secure.In addition, even if the later stage causes device to move because of artificial or other factors, because the first steel pole (1-1) and the second steel pole (1-2) length are all higher than 290mm, its size is more than most of surface mine medium-length hole blasting bore diameters, can ensure that plastic detonating tube wound on it is stuck on big gun hole, thus contain dropping of detonator completely.Through hole (2) ties up management for device, by rope class instrument therethrough, can realize the collection of many devices, store and transport.In general, this technical scheme is the most operable without skilled operator, easy to use, safe and reliable, stopped in surface blasting engineering because of during blast hole stemming process Nonel detonator inadvertently fall off the probability in big gun hole for the detonator of propagation of explosion section, solve the unnecessary trouble brought because propagation of explosion section detonator inadvertently falls off, it is ensured that the success rate of shot hole blasting, improve operation quality and efficiency.

Detailed description of the invention
Below according to accompanying drawing, this utility model is described further.
As shown in Figures 1 to 3, the device that during prevention blast hole stemming, Nonel detonator drops, it includes the first steel pole (1-1), the second steel pole (1-2) and through hole (2).Described first steel pole (1-1) and the second steel pole (1-2) are two steel cylinder of diameter and identical length etc., are attached by welding manner between them；The radius of described through hole (2) is less than described first steel pole (1-1), the radius of the second steel pole (1-2), and is only located at the side of the first steel pole (1-1)；The length of described first steel pole (1-1) and the second steel pole (1-2) is all higher than 290mm, and diameter is all higher than 30mm；The position of described through hole (2) is at distance the first steel pole (1-1) end points 70mm, and radius is 5mm.
Mine is on-the-spot in the open, and workmen, without earnestly seeking searching bulk stone, only needs directly on device welding center, the detonator being used for propagation of explosion part to be wound around a few, can realize detonator and fixedly secure.In addition, even if the later stage causes device to move because of artificial or other factors, because the first steel pole (1-1) and the second steel pole (1-2) length are all higher than 290mm, its size is more than most of surface mine medium-length hole blasting bore diameters, can ensure that plastic detonating tube wound on it is stuck on big gun hole, thus contain dropping of detonator completely.Through hole (2) ties up management for device, by rope class instrument therethrough, can realize the collection of many devices, store and transport.In general, the technical program solves the unnecessary trouble brought because propagation of explosion section detonator inadvertently falls off, and improves shotfiring safety, it is ensured that the success rate of shot hole blasting, improves operation quality and efficiency.
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its form or structure, do any change; everything has same as the present application or akin technical scheme, within all falling within protection domain of the present utility model.
