Background technology
With the continuous development of highway construction, highway spreads all over mountains and rivers and Plain, is limited by factors such as landform, on road
Tunnel Engineering is increased in line design, to adapt to the needs of route alignment.In previous Tunnel Blasting construction, since tradition is quick-fried
The limitation of broken technique, often occurs Tunnel Blasting safety accident, and tunnel safety explosion for a long time just becomes pendulum and constructing
A problem before unit plane.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides a kind of tunnel safety blast working device, carries
High blast working safety, and make it is simple, it is easy to operate, save cost, considerable economic benefit and society can be generated
Benefit.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of tunnel safety blast working
Device, including initiator, detonator, detonating needle, excitation needle and Nonel detonator, the initiator pass through two detonations of positive and negative anodes
Main line links together with excitation needle respectively, and the excitation needle is located in detonating needle, and the detonating needle and excitation needle are inserted together
Enter in detonator, the end of the detonator is connected with Nonel detonator, and the end of the Nonel detonator has been arranged in parallel more
A detonation tube bank, each detonation tube bank are connected with the detonator in corresponding quick-fried blasthole.
The excitation needle is that two 0.5mm conducting wires with insulated hull are mutually twisted together, and end is had one's hair trimmed with scissors, end
It is connect with detonation main line.
The utility model has an advantageous effect in that compared with prior art：The utility model uses a kind of self-control excitation
Needle detonation tube network blast working device avoids compared with traditional common electric cap demolition set technology because applying
Tool shock etc. generates early quick-fried caused safety in production caused by spark, electrostatic, stray electrical current, induced current etc. during work
Major accident substantially increases blast working safety, and makes simply, easy to operate, saves cost, produces considerable
Economic benefit and social benefit.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1 be initiator, 2 be detonator, 3 be detonating needle, 4 be excitation needle, 5 be Nonel detonator, 6 be detonation master
Line, 7 are detonation tube bank.
Specific implementation mode
As shown in Figure 1, a kind of tunnel safety blast working device of the utility model, including initiator 1, detonator 2, detonation
Needle 3, excitation needle 4 and Nonel detonator 5, the initiator 1 are connect with excitation needle 4 respectively by two detonation main lines 6 of positive and negative anodes
Together, the excitation needle 4 is located in detonating needle 3, and the detonating needle 3 and excitation needle 4 are inserted into detonator 2 together, described
The end of detonator 2 is connected with Nonel detonator 5, and the end of the Nonel detonator 5 has been arranged in parallel multiple detonation tube banks 7,
Each detonation tube bank 7 is connected with the detonator in corresponding quick-fried blasthole.
The excitation needle 4 is that two 0.5mm conducting wires with insulated hull are mutually twisted together, and end is had one's hair trimmed with scissors, end
End is connect with detonation main line 6.
The operation principle of the utility model：Detonation center of pin has two metal electrodes, and being inserted into detonator just makes the two electricity
Pole enters detonator inner cavity, in firing device（Initiator）It exports under forceful electric power field action, two electrodes electricity production, to strong compression tube chamber
In air dielectric and form shock wave, to excite the explosive charge of detonator tube wall, this explosion is along pipe propagation of explosion, to its end
End enters Nonel detonator, and Nonel detonator is excited to explode, then drives other detonator propagation of explosions, the ignition big gun of final relay-type
Blasting cap detonation in hole, explosive loading explosion, completes the detonation of entire section blasthole.
It is that the 0.5mm conducting wires with insulated hull are mutually twisted together by two that needle is excited in the utility model, and end is with cutting
Knife is had one's hair trimmed, and end is connect with detonation main line.
In the utility model initiation net take extension elementary errors in hole, hole extra-cluster connection detonation mode, number is outside each hole
The section alias of detonator takes mode in parallel between each detonating primer, to ensure the reliability and accuracy of initiation net.It is coupled
When it is noted that：The fastness in the connection direction and tie point of primacord；Detonator cannot be knotted and be drawn and attenuated；Detonating primer black glue
Cloth is tightly wrapped up from cluster detonator free end 10cm or more, after network joins well, to be had special messenger to be responsible for inspection, be confirmed errorless
Afterwards, Fang Zhun detonates.
The method that network connection mostly uses " bundle connects " in the utility model uniformly ties up detonator along detonator radial direction with adhesive plaster
At detonator tube body main charge position.Consider operating feature when quality and the binding of detonator, 20 are at most bundled on the outside of 1 hair detonator
Root detonator, compound relay-type bundle in network, and 2 hairs are led the detonator number that quick-fried detonator bundlees and should be controlled 40 on each relay point
Within root, adhesive plaster must not be less than 3 layers, it is important to which detonator, which will uniformly be arranged in detonator surrounding, to be tied up and want closely connected.
After powder squib bundlees in the utility model, excitation needle is inserted into 2cm in nonel tube, with detonation main line connection
Needle is excited, because excitation needle is to play the role of ignition by high voltage excitation spark, so the tape insulation copper that main line will use resistance small
Line.Traditional electric cap blasting technology is not required to installation excitation needle, and directly detonator twisted wire is connected on main line.
After security official evacuates personnel equipment in the utility model, guarded against, dynamiter connects excitation needle with main line
After, main line is connected on initiator, is checked initiator voltage, after reaching requirement voltage, is pressed detonation button.
The utility model increases blast working safety, avoids instead of electric detonator initiation detonator network technology
Electric cap causes the early quick-fried serious accident brought in carrying, misoperation；The technology also has stronger shock resistance simultaneously
Property, antistatic and anti-scattered strays fluidity, avoid because in work progress tool hit etc. generate spark, electrostatic, stray electrical current, induction
Electric current may cause early quick-fried caused major accident of keeping the safety in production.
The utility model self-control excitation needle material therefor is the enameled wire of tape insulation skin, and cost is relatively low, and excitation needle makes letter
It is single, it is easy to operate, waste and scrap can be not only made full use of, saves cost, and can guarantee the safety of explosion, there is good economy
Benefit and social benefit.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
It is lower that various changes can be made.
