Description

Multi-functional priming apparatus

The utility model relates to a kind of mine using blasting machine, particularly a kind of explosion-proof type electric cap exploder.

All kinds of exploders that use in the present mining at home and abroad have only the detonating primer function, by its " safety regulations in coal mine " regulation: " after the energising; when charging blast-hole does not ring; twist together into short circuit; pull up key; after waiting 5 minutes; should remove blowing out bus after blowing out, could check along the line, find out the reason of not ringing ", but under the specific environment of Coal Production; the person of blowing out is because of its troublesome poeration; the time of blowing out is long; efficient is low; and the phenomenon of operating against regulations that bus is not plucked in frequent appearance, on the other hand, because the detonation power of exploder is very big; rich energy is very big in actual blowing out, under normal circumstances, this energy is to discharge by discharge loop, damages if discharge resistance loses efficacy, disconnected or the ms switch of circuit rust faults such as rotary contact is loosening continually, the capital excessive amount of electrical energy occurs and puts halfway phenomenon, and the personnel that blow out do not pluck bus again with regard on line as this moment, search etc. and to operate against regulations, banger will inevitably occur and collapse people's accident.Another defective that existing exploder exists is that its output voltage is stable inadequately, and overtension is easy to damage the big gun machine, and brownout again can not detonating primer.

It is a kind of simple in structure, reasonable in design that the purpose of this utility model will provide exactly, and output voltage stabilization can conveniently be realized safety interlocking after blowing out, and need not pluck the multi-functional priming apparatus that bus just can carry out next step operation.

The utility model adopts technical scheme as described below for achieving the above object: multi-functional priming apparatus comprises explosion-resistant enclosure, two binding posts, ms switch, power supply E, oscillating circuit, boost rectifying circuit, accumulator and a safety interlock system, this safety interlock system be one by K switch ₁, K ₂The linked switch of forming, K switch ₁, K ₂Be open type, K switch ₁Two ends a, b be connected on triode GB in the oscillating circuit ₁Emitter stage and base stage between, K switch ₂Two ends c, d be connected between two binding posts, the control button of linked switch is installed on the explosion-resistant enclosure.K in the linked switch ₁, K ₂Can for the dry-reed switch, also can mechanical rotation formula switch, can also be mechanical pull type switch, can also be other structure, link as long as can realize.This exploder also has a mu balanced circuit, and this circuit is by the switch triode GB of bleeder circuit, series connection ₂, GB ₃Form, bleeder circuit is connected in parallel on the two ends of accumulator, and its dividing point is connected to triode GB through a light emitting diode ND ₂Base stage, triode GB ₃Emitter stage connect positive source, its colelctor electrode meets the triode GB of oscillating circuit ₁Base stage.

It is like this work: when exploder begins charging, when the accumulator two ends reached rated voltage, bleeder circuit was given triode GB through light emitting diode ND ₂Provide a bias voltage to make its conducting, simultaneously triode GB ₃Also conducting is with the triode GB of oscillating circuit ₁The base stage short circuit, oscillating circuit is quit work, this moment is bright as the light emitting diode N D of accurate quick-fried indication, shows that accumulator has rated voltage, at any time can be in order to detonation.After having put big gun, the linked switch of safety interlock system is placed the position of lock, this moment, the exploder two-terminal was in short-circuit condition, and oscillating circuit is suppressed the failure of oscillations.

Adopt the multi-functional priming apparatus of said structure because safety interlock system has been arranged, put the position that safety interlock system is placed behind the big gun lock, can not pluck bus, carrying out line inspection lineman quickly and easily does, improved and blown out efficient, reduce the possibility that the workman operates against regulations, fundamentally solved the general difficult problem that exploder is hurted sb.'s feelings scientifically and rationally; The mu balanced circuit of Zeng Jiaing can make shot firing operation carry out under the situation of more directly perceived, safety and reliability in addition.

Below in conjunction with accompanying drawing the utility model is described in detail.
