Description

Airspace device for deep hole blasting powder charge
Technical field
The present invention relates to a kind of airspace devices for deep hole blasting powder charge, belong to blasting engineering auxiliary device technology Field.
Background technique
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 that there are unit consumption is big, detonation first pressing is excessively high, the overground disadvantage of rock so that the energy efficient benefit of explosive It is low with rate, and it is also easy to produce bulk and foundation, bring the problems such as blasting vibration harm.Air-decking technique can reduce Explosive makes blast pressure in hole axially be distributed more evenly along blasthole, 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 range, improves the effective rate of utilization of explosive blasting energy, To reduce blasting cost, controled blasting harm.Airspace device i.e. air column and explosive, air column and stemming it Between the spacer that is arranged to bear the weight of explosive and stemming.Currently used air-spacer is air bag, unit price height, It is cumbersome, loading rate is reduced, blasting cost is increased.
Summary of the invention
The technical problems to be solved by the present invention are: providing, one kind is low in cost, easy to operate to be filled for deep hole blasting The airspace device of medicine, to improve loading rate, reduce blasting cost.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: the airspace for deep hole blasting powder charge Device, the column casing including hopper and hollow structure, column casing top are standard-sized sheet mouth structure, the circumferentially spaced setting of column casing side wall There is a multiple groups sliding slot, every group of sliding slot as starting point and is parallel to the axis direction of column casing and be arranged using column casing top, between different groups Sliding slot stroke is different；Hopper is sheathed in column casing, the corresponding hopper of one group of sliding slot, is provided at least two pieces card on the outside of hopper It hooks, hook shape specification is adapted with sliding slot, hopper is slided along sliding slot to sliding slot end and is hung by hook In on the side wall of column casing.
Further, hook is symmetrically arranged two pieces；One group of sliding slot is symmetrically arranged two pieces.
Further, feed hopper bottom is provided with circular hole compatible with detonator.
Further, hopper and column casing are PVC material.
The beneficial effects of the present invention are: column casing outer diameter is slightly less than blasthole diameter, and sliding slot stroke is according to airspace when implementing Charge positions are determining, the good column casing of pre-production and hopper.When powder charge, first put column casing into blasthole, then by a hopper along The longest sliding slot of stroke is transferred, then powder charge, drain hopper under the sliding slot then grown further along stroke second, then powder charge again, directly To decentralization one hopper of top layer, it is packed into choke material, entire powder charge process is completed.The present invention is low in cost, easy to operate, Loading rate can be improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of column casing in the present invention；
Fig. 2 is the structural schematic diagram of hopper in the present invention；
Fig. 3 is overall structure diagram when implementing in the present invention.
Marked in the figure: 1- column casing, 2- sliding slot, 3- hopper, 4- hook, 5- detonator, 6- blasthole, 7- powder charge section, 8- air Section, 9- block section, 10- detonator.
Specific embodiment
For ease of understanding with the implementation present invention, the preferred embodiment of the present invention combination attached drawing is selected to be described further.
As shown in Figure 1 to Figure 3, the present invention includes the column casing 1 of hopper 3 and hollow structure, is open knot at the top of column casing 1 Structure, 1 side wall of column casing is circumferentially spaced to be provided with multiple groups sliding slot 2, and every group of sliding slot 2 is using 1 top of column casing as starting point and parallel It is arranged in the axis direction of column casing 1,2 stroke of sliding slot between different groups is different；Hopper 3 is sheathed in column casing 1, one group of sliding slot 2 A corresponding hopper 3, the outside of hopper 3 are provided at least two pieces hook 4, and 4 shape specification of hook is adapted with sliding slot 2, so that Hopper 3 can be slided to 2 end of sliding slot along sliding slot 2 and be hung on the side wall of column casing 1 by hook 4.Wherein sliding slot 2 can It, can also be for set on the U-type groove structure of 1 inner wall of column casing for through the hatch frame of 1 side wall of column casing.
Simple and reliable for structure to make, hook 4 is symmetrically arranged two pieces；One group of sliding slot 2 is symmetrically arranged two pieces.Material PVC material can be used in bucket 3 and column casing 1.
It is passed through from hopper for convenience of detonator 5,3 bottom of hopper is provided with circular hole compatible with detonator 5.
When implementation, 1 outer diameter of column casing is slightly less than 6 diameter of blasthole, and 2 stroke of sliding slot is determined according to underground borehole blasting position, in advance First make column casing 1 and hopper 3.When powder charge, first column casing 1 is put into blasthole 6, it is then that a hopper 3 is longest along stroke Sliding slot 2 is transferred, then powder charge, then further along the lower drain hopper 3 of the long sliding slot 2 of stroke second, then powder charge again, until decentralization is most After the hopper 3 of one, upper layer, it is packed into choke material, entire powder charge process is completed.
