Description
Technical field
The present invention relates to a kind of explosive charge equivalent test device and method of testing.
Background technology
With the fast development of national economy, Rock Blasting Technology is each in water conservancy and hydropower, mine, traffic and urban construction etc.
Individual field is obtained a wide range of applications, and with bringing huge economic benefit.Due to the explosive reaction of explosive be a high temperature,
The transient process of high pressure and high speed, by the complicated and changeable of quick-fried Rock Nature and blasting condition, and rock blasting destructive process is again
One is lasted extremely of short duration process, therefore causes great difficulty to directly observation and research rock mass damage mechanism.Especially
The rendrock dosage typically used when being and being simulated explosion Rock Fracture Processes for laboratory is low, how could be more smart
The acting ability of true and easy control explosive charge, the specific value of testing laboratory's blasting energy is tested for the later stage
Room shot rock experiment has great importance.
The monitoring mode of traditional commercial explosive energy has a lot, but still suffers from blank for test in laboratory.Industry
It is upper at present be exactly more widely traditional lead cast and modern typical quick-fried hot, Underwater Explosion Method these three on industry
The detection mode of explosive energy.Lead cast needs cast the sample of some commercial explosives of internal storage in the lead of a cylinder,
When ignition, lead cast tube can be expanded by heat, will be to lead cast tube when stress reaches to a certain degree
Volume has certain change, and the specific energy of selected commercial explosive sample is calculated finally by the volume change of lead cast tube.It is quick-fried
Hot method is compared close with lead cast, is all to fully rely on the heat of explosive to judge the energy of explosive.The third mode is just
Underwater Explosion Method, Underwater Explosion Method is the advanced technology introduced from foreign country, but a kind of this method of detection need it is specific
Environment, a kind of this explosive method all completed under water, and this method is mainly sent out under water by testing commercial explosive
The change of data value between water impact wave parameter and gas bubble pulsation cycle is caused to judge the energy of explosive when raw blast
Size.Detection material category required for traditional mode is various, and the method such as detection also needs to specific environmental requirement under water, but
It is for simple required for laboratory and can guarantee that laboratory energy monitoring requirement, can not fully meets, this is just to experiment
The monitoring of room blasting energy brings bigger difficulty.
Therefore, prior art needs further improvement and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of explosive charge equivalent test device and
Method of testing, with it is simple, fast and accurately measurement and the low dosage explosive used by evaluation experimental room do work ability.
In order to solve the above technical problems, the present invention program includes：
A kind of explosive charge equivalent test device, it includes the protection tube being made up of rigid transparent material, wherein, protection
Sliding plunger is provided with sleeve pipe, sliding plunger can be slided in protection tube, sliding plunger is dynamic close with protection tube inwall
It is provided with envelope, one end closing of protection tube, the blind end and sliding plunger formation explosion chamber, explosion chamber for explosive
Detachable medicine storage, be provided with resistance trigger in detachable medicine storage；Graduation mark is provided with protection tube.
Described explosive charge equivalent test device, wherein, a gear is provided with the zero graduation line of above-mentioned graduation mark,
In original state, sliding plunger coincides with gear.
A kind of method of testing using the explosive charge equivalent test device, it comprises the following steps：
Explosive is placed in detachable medicine storage and is placed in protective sleeve, is rubbed according to the metering of explosive selection correspondence
The sliding plunger of coefficient is wiped, sliding plunger is placed at gear, and it is coaxial with protective sleeve；It is then switched on resistance trigger
Main firing explosive, air instantaneous expansion promote sliding plunger moved along protection tube, according to the displacement of sliding plunger with
And corresponding coefficient of friction, obtain explosive charge equivalent.
A kind of explosive charge equivalent test device and method of testing that the present invention is provided, be not put to the test dose, test site
Deng limitation, the quantization of the acting ability of explosive can be carried out in laboratory, meeting laboratory, to carry out laboratory easy accurate
The acting ability of various dose explosive is detected, present system simple structure, low cost, the test period is short, easy to operate, is easy to
Promote.
