Background technology
Drillhole blasting is the common technology of rock excavation, is widely used in the fields such as water conservancy and hydropower, mine, traffic. Traditional continuous cylindrical charge exists that unit consumption is big, detonation first pressing is too high, the overground shortcoming of rock so that the effective utility of laser power of explosive is low, and is easily generated bulk and foundation, brings the problems such as blasting vibration harm. Air-decking technique can reduce the explosive initial peak pressure to big gun hole surrounding rock, blast pressure in hole is made to obtain evenly along big gun hole axial distribution, thus reducing or avoid the over grind of near region, big gun hole country rock, expand rupture zone scope, improve the effective rate of utilization of explosive blasting energy, thus reducing blasting cost, controled blasting harm. The spacer that namely airspace device is arranged between air column and explosive, air column and stemming is to bear the weight of explosive and stemming. Air-spacer conventional at present is air bag, and its unit price is high, complex operation, reduces loading rate, adds blasting cost.
Summary of the invention
The technical problem to be solved is: provide a kind of with low cost, easy to operate blasting engineering airspace device, to improve loading rate, to reduce blasting cost.

Wherein, screw connection structure between bottom fixing masthead portion and action bars can adopt following attachment structure to substitute: by the mode clamping of groove with projection matched in clearance bottom fixing masthead portion and action bars, preferably, there is bottom action bars centralized positioning groove, fix masthead portion entirety and centralized positioning groove clamping.
Further: action bars outer surface is provided with the graduation mark arranged along its length.
Further: pole is arranged along fixing bar circumferencial direction uniform intervals.
Further: pole quantity is 4～8.
Further: action bars top is provided with handle.
The invention has the beneficial effects as follows: during enforcement, integral installation of the present invention is prepared, now spring is in compressive state, bracing frame apparent size is less than big gun hole internal diameter, when design attitude sent into by bracing frame, cutting off connection rope at action bars top, pole is stuck in big gun hole inwall by spring reset elastic force moment, action bars departs from bracing frame, loads explosive or stemming on bracing frame top; Repeating said process, complete powder charge, primacord may be disposed at and flexibly connects between beyond the region of objective existence end and big gun hole inwall. Abutting intensity for improving pole with big gun hole inwall, cut off connection rope and make device card when big gun hole, spring still keeps compressive state. The present invention is with low cost, easy to operate.

Detailed description of the invention
For ease of understanding and implementing the present invention, the preferred embodiments of the present invention are selected to be described further in conjunction with accompanying drawing.
As it is shown in figure 1, the present invention includes action bars 1, bracing frame; Action bars 1 has the action bars connecting hole arranged along its axis direction; Bracing frame includes fixing bar 3, fixing bar 3 has the fixing lever attachment hole arranged along its axis direction, fixing bar 3 outer wall top is provided with at least two pieces pole 4 being hinged, by flexibly connecting thing connection between adjacent two pieces pole 4, the outer wall of every pole 4 is connected with fixing bar 3 outer wall each through spring 5, and every pole 4 lower end has been fixedly connected with connection rope 2; It is threaded connection bottom fixing bar 3 top and action bars 1, connects after rope 2 starts to pass fixing lever attachment hole, action bars connecting hole successively bottom fixing bar 3, be fixedly installed on action bars 1 top, spring 5 can be made to be in compressive state.
As shown in Figure 2, during enforcement, integral installation of the present invention is prepared, now spring 5 is in compressive state, and bracing frame apparent size is less than big gun hole 7 internal diameter, when design attitude sent into by bracing frame, connection rope 2 is cut off at action bars 1 top, pole 4 is stuck in big gun hole 7 inwall by spring 5 reseting elasticity moment, and action bars 1 departs from bracing frame, loads explosive or stemming on bracing frame top; Repeating said process, complete powder charge, primacord may be disposed at and flexibly connects between beyond the region of objective existence end and big gun hole 7 inwall. Abutting intensity for improving pole 4 with big gun hole 7 inwall, cut off connection rope 2 and make device card when big gun hole 7, spring 5 still keeps compressive state. The present invention is with low cost, easy to operate.
Wherein, screw connection structure between bottom fixing bar 3 top and action bars 1 can adopt following attachment structure to substitute: by the mode clamping of groove with projection matched in clearance bottom fixing bar 3 top and action bars 1, groove can be arranged on fixing bar 3, can also be arranged on action bars 1, groove can be body circumferencial direction arrange one or more, only can also arrange one in center, projection is matched, preferably, there is bottom action bars 1 centralized positioning groove, fix bar 3 top entirety and centralized positioning groove clamping. Due to groove and projection matched in clearance, cutting off connection rope 2 and make device card when big gun hole 7, action bars 1 and bracing frame can automatically disengage, and implement more convenient.
Bracing frame installation site can rule of thumb control, it is possible to adopts the mode of simple marking, it is preferable that action bars 1 outer surface is provided with the graduation mark arranged along its length, can conveniently control bracing frame installation site, improves charging quality.
Preferably, pole 4 is arranged along fixing bar 3 circumferencial direction uniform intervals, so that device uniform force, does not deviate by Bao Kong center, improves charging quality.
Preferably, pole 4 quantity is 4～8. If pole 4 quantity is very little, it is impossible to completely enclosed big gun hole, explosive can be missed; If pole 4 quantity is too many, connects rope 2 and just compare many, operate relatively cumbersome.
Preferably, action bars 1 top is provided with handle 6, convenient operation.
Specifically, action bars 1, fixing bar 3 all can adopt pipe to make, flexibly connecting thing and then can adopt various cloth between adjacent two pieces pole 4, flexibly connect thing owing to wanting load-bearing simultaneously, should possess sufficient intensity. It addition, for convenience of the setting connecting rope 2, pole 4 lower end, action bars 1 top can arrange connecting hole or hook, connect rope 2 for colligation.
