Abstract
The utility model relates to the detonator detonating needle that a kind of mine is fixed with band device, the main material of fixing clamp is PVC plastic, and shape is circular boop shape, long 10mm, wide 4mm, thick 1.5mm, and fixing clamp is composed of two semicircles, can open and close for fixing.The utility model solves the fixation problem between plastic detonating tube and detonating needle, pass through being fixed for fixing clamp and being connected and fixed for nylon cable tie, plastic detonating tube is effectively prevented because the percussion that detonation generates slides from detonator detonating needle, ensure that detonation quality and effect.The utility model structure is simple, cheap, easy to use, has good fixed function, is added to double insurance for detonation, improves the economic benefit of Blasting Enterprise and the safety of explosion.
Description
Technical field
The utility model relates to be used to ignite the device of plastic detonating tube in a kind of detonating tube remote initiation system, specially
A kind of mine is fixed with band the detonator detonating needle of device.
Background technique
Detonator is also referred to as Nonel pipe, is to use white plastic hose (translucent) made of high pressure polyethylene, outer diameter 3mm,
Internal diameter is 1.5mm, the booster explosive that inner wall has one layer of hexogen to mix with aluminium powder, this thin layer medicine can propagate sky due to pipe effect
Gas shock wave (smaller than cut off diameter), igniter cap, industrial detonator, common primacord, match board head etc. all can generate shock wave
Initiating equipment can ignite plastic detonating tube.After detonator is fired, a kind of special detonation, detonation wave are formed in pipe
It is propagated with constant speed.Detonator detonation is easy to operate light, and use is safe and accurate, reliable；It can anti-stray current, electrostatic and thunder and lightning；
Raw material is plastics, and the dosage of metal and cotton yarn is few；Detonator transportation safety, generally uses.
Blasting system composition: detonator firing device (common electric detonator initiation device)+electric wire+detonating needle+preposition safety
Detonator+propagation of explosion Nonel detonator.Detonating needle is actually a sparker, and detonation center of pin has two metals electric
Pole, being inserted into detonator just makes the two electrodes into detonator inner cavity, in the case where firing device (initiator) exports forceful electric power field action,
Two electrodes generate spark discharge, thus air dielectric in strong compression lumen and form shock wave, to excite detonator pipe
The explosive charge of wall, this explosion enter Nonel detonator to its end, and Nonel detonator is excited to explode along pipe propagation of explosion, then
Other detonator propagation of explosions, blasting cap detonation in the ignition blasthole of final relay-type are driven, entire section big gun is completed in explosive loading explosion
The detonation in hole.Device is fixed due to no on detonator and detonating needle, in mine blasting engineering, when multiple groups detonator
When connecting in blasting network, preceding group of detonator rear group of the detonator of pullling power easily and cause to be formed that detonates detonates from detonator
It falls off on needle, forms blind big gun, seriously affected blasting quality.So there is an urgent need to it is a kind of it is easy to carry, easy to use, can be continuous
The detonator detonating needle with fixed device used.
Utility model content
In order to solve the fixation problem between plastic detonating tube and detonating needle, prevent detonator from sliding influence from detonating needle
Detonation Initiation Effect, the utility model provide the detonator detonating needle that a kind of mine is fixed with band device.
The utility model uses following technical scheme: increasing structure 1 on detonator detonating needle top, in detonator and detonation
Needle connecting portion increases structure 2, and structure 1 is connect with structure 2 with nylon cable tie.Structure 1 is the locker of nylon cable tie, structure
2 be the hollow circular boop that internal diameter is 2.5mm and there is nylon cable tie in outside.
The utility model has the following characteristics that
1. material is simple with manufacture craft, it can be recycled, greatly reduce cost.
2. easy to use, scene can easily reach expected engine request.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the utility model embodiment.
Fig. 2 is the fixing clamp diagrammatic cross-section of the utility model embodiment.
Fig. 3 is the nylon cable tie front view of the utility model embodiment.
In figure, 1- detonating needle shell, 2- conducting wire, 3- detonating needle, 4- nylon cable tie lock, 5- nylon cable tie fixed station, 6-
Nylon cable tie, 7- circular boop shape fixing clamp.
Specific embodiment
It please refers to shown in Fig. 1, that show the specific structures of the utility model embodiment, in use, by detonating needle
It is inserted into inside detonator, circular boop shape fixing clamp is fixed on to the junction of detonator and detonating needle, then nylon cable tie is passed through
Lock is fixed, and the pulling force that the frictional force and nylon cable tie generated using pressure is generated prevents the landing of detonator.
Claims (2)
1. a kind of mine is fixed with band the detonator detonating needle of device, material is PVC plastic, it is characterised in that increasing one can
Circular boop shape for being connected and fixed and the fixing clamp with nylon cable tie have band lock on detonating needle, can effectively prevent and lead
Booster and detonating needle fall off.
2. the detonator detonating needle that a kind of mine according to claim 1 is fixed with band device, it is characterised in that detonator
With detonating needle by the fixing clamp it is fixed after, then connected by nylon cable tie, dual fixation played to detonator and detonating needle
Effect.
