Description
Technical field
The present invention relates to a kind of blasting engineering airspace device.
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.Tradition
Continuous cylindrical charge have that unit consumption is big, detonation first pressing is too high, the overground shortcoming of rock so that the Energy Efficient profit of explosive
It is low with rate, and bulk and foundation are also easy to produce, bring the problems such as blasting vibration harm.Air-decking technique can be reduced
Explosive makes blast pressure in hole axially be distributed evenly along blasthole, so as to drop the initial peak pressure of blasthole surrounding rock
Excessive crushing that is low or avoiding blasthole near region country rock, expands rupture zone scope, improves the effective rate of utilization of explosive blasting energy,
So as to reduce blasting cost, controled blasting harm.Airspace device i.e. air column and explosive, air column and stemming it
Between the spacer that sets to bear the weight of explosive and stemming.Conventional air-spacer is air bag at present, its unit price height,
It is cumbersome, loading rate is reduced, blasting cost is added.
The content of the invention
The technical problems to be solved by the invention are：There is provided between a kind of blasting engineering air with low cost, easy to operate
Every device, to improve loading rate, reduction blasting cost.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：Blasting engineering airspace device, including
Action bars, support frame；Action bars has the operation lever attachment hole set along its axis direction；Support frame includes fix bar, fixed
Bar has provided with least two pieces pole being hinged at the top of the fixation lever attachment hole set along its axis direction, fix bar outer wall,
Connected between adjacent two pieces pole by being flexibly connected thing, the outer wall of every pole is connected by spring with fix bar outer wall,
Every pole lower end has been fixedly connected with connecting rope；It is connected through a screw thread at the top of fix bar with action bars bottom, connecting rope is from admittedly
Fixed pole bottom starts to sequentially pass through after fixed lever attachment hole, operation lever attachment hole, is fixedly installed at the top of action bars, connecting rope peace
Spring is enabled to be in compressive state after installing.
Wherein, the screw connection structure between at the top of fix bar and action bars bottom can be substituted using following attachment structures：
With the clamping by way of groove and projection gap coordinate of action bars bottom at the top of fix bar, it is preferable that action bars bottom has
Overall and centralized positioning groove clamping at the top of centralized positioning groove, fix bar.
It is further:Operation rod outer surface is provided with the graduation mark set along its length.
It is further:Pole is set along fix bar circumferencial direction uniform intervals.
It is further:Pole quantity is 4~8.
It is further:Handle is provided with the top of action bars.
The beneficial effects of the invention are as follows：During implementation, entirety of the invention is assembled, now spring is in compressive state, branch
Support apparent size is less than blasthole internal diameter, and when support frame sends into design attitude, connecting rope, spring are cut off at the top of action bars
Pole is stuck in blasthole inwall by reseting elasticity moment, and action bars departs from support frame, and explosive or stemming are loaded on support frame top；
Said process is repeated, powder charge is completed, primacord may be disposed between flexible connection beyond the region of objective existence end and blasthole inwall.For improve pole with
Blasthole inwall abuts intensity, cuts off connecting rope so that device card is in blasthole, spring still keeps compressive state.Cost of the present invention is low
It is honest and clean, easy to operate.

Embodiment
For ease of understanding and implementing the present invention, the preferred embodiments of the present invention combination accompanying drawing is selected to be described further.
As shown in figure 1, the present invention includes action bars 1, support frame；Action bars 1 has the operation set along its axis direction
Lever attachment hole；Support frame includes fix bar 3, and fix bar 3 has the fixation lever attachment hole set along its axis direction, fix bar 3
Provided with least two pieces pole 4 being hinged at the top of outer wall, connected between adjacent two pieces pole 4 by being flexibly connected thing, every branch
The outer wall of bar 4 is connected by spring 5 with the outer wall of fix bar 3, and every lower end of pole 4 has been fixedly connected with connecting rope 2；Fix bar
3 top be connected through a screw thread with the bottom of action bars 1, connecting rope 2 sequentially passed through since the bottom of fix bar 3 fixed lever attachment hole,
Operate after lever attachment hole, be fixedly installed on the top of action bars 1, connecting rope 2 enables to spring 5 to be in compression shape after installing
State.
As shown in Fig. 2 when implementing, entirety of the invention is assembled, now spring 5 is in compressive state, support frame outward appearance
Size is less than the internal diameter of blasthole 7, when support frame sends into design attitude, cuts off connecting rope 2 at the top of action bars 1, spring 5 resets
Pole 4 is stuck in the inwall of blasthole 7 by elastic force moment, and action bars 1 departs from support frame, and explosive or stemming are loaded on support frame top；
Said process is repeated, powder charge is completed, primacord may be disposed between flexible connection beyond the region of objective existence end and the inwall of blasthole 7.To improve pole 4
Intensity is abutted with the inwall of blasthole 7, connecting rope 2 is cut off so that device card is in blasthole 7, spring 5 still keeps compressive state.The present invention
It is with low cost, easy to operate.
Wherein, the screw connection structure between the top of fix bar 3 and the bottom of action bars 1 can be replaced using following attachment structures
Generation：The top of fix bar 3 and the clamping by way of groove and projection gap coordinate of the bottom of action bars 1, groove can be arranged at solid
In fixed pole 3, can also be arranged on action bars 1, groove can be body circumferencial direction set it is one or more, can also
One only is set in center, projection is matched, it is preferable that the bottom of action bars 1 has centralized positioning groove, fix bar 3
Top entirety and centralized positioning groove clamping.Because groove and projection gap coordinate, connecting rope 2 is cut off so that device card is in blasthole 7
When, action bars 1 can be automatically disengaged with support frame, implement more convenient.
Support frame installation site can be controlled rule of thumb, also can be by the way of simple marking, it is preferable that outside action bars 1
Surface is provided with the graduation mark set along its length, can conveniently control support frame installation site, improve charging quality.
Preferably, pole 4 is set along the circumferencial direction uniform intervals of fix bar 3, to cause device uniform force, does not deviate by
Blasthole center, improves charging quality.
Preferably, the quantity of pole 4 is 4~8.If the quantity of pole 4 is very little, it is impossible to which completely enclosed blasthole, explosive can be missed；
If the quantity of pole 4 is too many, connecting rope 2 is just relatively more, operates relatively cumbersome.
Preferably, the top of action bars 1 is provided with handle 6, convenient operation.
Specifically, action bars 1, fix bar 3 can be made using pipe, the flexible connection thing between adjacent two pieces pole 4
Various clothes can be then used, while being flexibly connected thing due to wanting load-bearing, should possess sufficient intensity.In addition, for convenience of connecting rope 2
Set, the lower end of pole 4, the settable connecting hole in the top of action bars 1 or hook, for colligation connecting rope 2.
