Description
Technical field
The present invention relates to a kind of safety blasting device, belong to field of civil engineering.
Background technology
Blasting network initiation ends generally use electric cap or Nonel detonator are detonated, and are used as using Nonel detonator
Quick-fried end, especially high intensity high precision fuse blasting cap, the increase of explosive use cost can be caused, and operate extremely inconvenience；
Facilitate but easily disturbed by electrostatic, radio frequency electrical and stray electrical current as initiation ends, operation using electric cap, and easily
Trigger early quick-fried accident, there is larger potential safety hazard.
The content of the invention
In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of safety blasting dress
Put, it is rational in infrastructure, it is safe to use.
In order to solve the above technical problems, the present invention adopts the technical scheme that, a kind of safety blasting device, including outer barrel
Body, middle cylinder and interior cylinder, middle cylinder are socketed in outer barrel body, and interior cylinder is socketed in middle cylinder, outside
Cylinder lower end closed；The lower end of the middle cylinder is provided with end plate, and burning exploding wire is provided with end plate, and burning exploding wire is worn
The both ends for crossing end plate and the exploding wire that burns are respectively arranged with the both ends of end plate；The middle cylinder is internally provided with packaging ring,
Packaging Paper is provided with packaging ring, middle part powder charge chamber is provided between packaging ring and end plate, powder charge intracavitary in middle part is filled with medicine head；
The middle cylinder inwall epimere is provided with internal thread, and external screw thread is provided with interior cylinder outer wall, and internal thread is matched somebody with somebody with external screw thread
Close and set；Connection ring, middle cylinder top are provided between middle cylinder top outer wall and the top inwall of outside cylinder
Outer wall is fixedly connected with the top inwall of outside cylinder by connection ring, between the inwall of the outer wall of middle cylinder and outside cylinder
Drug-filling cavity is provided with, explosive is filled with drug-filling cavity；Rubber stopper is provided with the interior cylinder, the both ends of rubber stopper are arranged at
Two fairleads are provided with interior cylinder, in rubber stopper, setting is leaded in fairlead, and the both ends of lead are higher than interior cylinder
End face.
Optimize, above-mentioned safety blasting device, some strip grooves are provided with the outer surface of the outside cylinder.
Optimize, above-mentioned safety blasting device, some exhaust holes are provided with the rubber stopper.
The advantage of the invention is that it can overcome the drawbacks of prior art, novelty reasonable in design.The design of the application
By the way that the lead of ignition and the medicine head of ignition are provided separately.When needing to ignite, inside is made by rotating inner part cylinder
Cylinder moves in middle cylinder towards packaging ring, and lead contacts after wearing out Packaging Paper with the medicine head of ignition, and two leads lead to
Medicine head burnup pilot combustion exploding wire after electricity, the explosive in drug-filling cavity is ignited so that demolition set occurs after burning exploding wire burning
Blast.Such mode causes lead and the medicine head of ignition to be provided separately, and contacts, prevents quiet by both when needing to ignite
Electricity, radio frequency electrical and stray electrical current interference and trigger early quick-fried accident, add the security of demolition set.Strip groove is convenient
Outside cylinder ruptures in explosion time.Exhaust hole reduces air drag when interior cylinder moves in middle cylinder.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
In figure：1 it is outside cylinder, 2 be middle cylinder, 3 be interior cylinder, 4 be end plate, 5 be burning exploding wire, 6 is envelope
