Description
Technical field
The utility model belongs to the device of pack conveying technology more particularly to deep hole safe transport explosive.
Background technique
Deep hole blasting refers to the shot hole blasting technology that bore diameter is greater than 75mm, hole depth is greater than 5m.Deep hole blasting has single
The small, high production efficiency low with explosive unit consumption of position drilling amount and convenient for using comprehensive mechanization construction carry out explosion, dig fill,
The advantages that hauling operation, is widely used in outdoor and underground excavation project.Deep hole blasting can be with presplit blasting, photoface exploision and milli
The technologies such as second explosion combine, to obtain smooth excavation face, adjoining rock stability, the effect for improving engineering construction quality, deep hole at present
The powder charge delivery method of explosion has directly to broadcast explosive and hook using hook to be conveyed down, since blasthole is deeper, directly from hole
Explosive is sent into bottom by mouth, is not only increased degree of packing, is become coupling charging, influences demolition effect；And explosive is impacted,
It is possible that will cause serious safety consequences.It is conveyed using hook, increase artificially causes blasting charge breakage probability, especially in underground
The more rich region of water, pack rupture, removes low explosive performance, influences demolition effect, all there is wind for safety and quality aspect
Danger.
Summary of the invention
The shortcomings that the purpose of the utility model is to overcome the conveyings of existing deep hole blasting operation explosive provides a kind of operation letter
Single, safety explosive conveyer.
Technical solution used by the utility model is a kind of deep hole blasting operation explosive conveyer, is characterized by, it
Main body be a tubulose powder charge casing, internal diameter be greater than powder stick diameter, outer diameter be less than bore diameter, the upper end of powder charge casing
For open type, for both sides symmetric design there are two lifting rope hole, lifting rope passes through lifting rope hole, and powder charge casing bottom designs one and draws off explosive
Switch.
The utility model is prevented explosive from contacting friction with blasthole and explosive is caused to rupture, will be fried by a powder charge casing
Medicine is sent into the lower section of blasthole, and the switch by drawing off explosive separates explosive and powder charge casing, and operating process is simple, safe.
The switch for drawing off explosive of the powder charge casing bottom is made of baffle, rotating bar, support rod, draught line, dress
There are four hole, two holes that rotating bar passes through, one end of baffle is fixedly connected the design of medicine casing bottom with rotating bar, is supported
Bar passes through remaining two hole, and support rod is located at the lower section of baffle, one end connection of draught line and support rod.
Powder charge casing is put into blasthole certain depth (not on earth), so that support rod is detached from powder charge casing, gear by draught line
One end of plate loses support, and under its gravity, baffle is rotated down by shaft of rotating bar, and open bottom, explosive is fallen.
Rotating bar centerline axis is higher than support rod, the Weir Plate Thickness that the height of the two difference is 1/2 upwards.Guarantee in this way
Support rod acts on lower baffle plate in level.
Rotating bar is parallel with support rod.The joint angle of baffle and rotating bar is at 90 degree.
The diameter of powder charge casing is D, and the width of baffle is 0.2-0.9D.
The internal diameter of powder charge casing is greater than powder stick diameter 10-20mm.It is skidded off with being easy to explosive cartridge.
Design has multiple simultaneous gas vents that sluice on the side wall of powder charge casing.
The utility model structure is simple, can effectively reduce the intensity of labour and improve safe operation performance, be easy to
Operation, while time saving and energy saving raising work efficiency.
Detailed description of the invention
Fig. 1 is the using state structure diagram of the utility model；
Fig. 2 is the bottom substance schematic diagram of the utility model；
Wherein: 1 powder charge casing, 11 lifting rope hole, 12 rotating bar, 13 baffle, 14 support rod 15 sluices and the traction of 2 lifting rope 3 of gas vent
4 powder stick of line.
Specific embodiment
The utility model is described in detail below with reference to view, cited embodiment can make the skill of this profession
Art personnel more understand the utility model, but do not limit the utility model in any form.
As shown in Figure 1, 2, a kind of deep hole blasting operation explosive conveyer, its main body are the powder charge casings 1 of a tubulose,
Its internal diameter is greater than powder stick diameter, and outer diameter is less than bore diameter, and the internal diameter of powder charge casing is greater than 4 diameter 10-20mm of powder stick.Such as: medicine
Coil diameter is φ 60mm, and powder charge casing selects internal diameter for the PVC plastic pipe of φ 75.The upper end of powder charge casing is open type, both sides
There are two φ 10mm lifting rope holes 11 for symmetric design, use φ 9mm nylon rope as lifting rope 2, pass through lifting rope hole, the side of powder charge casing
Design has multiple sluice simultaneous gas vent and gas vents 15 to influence cylindrantherae sinking to prevent water in hole deeper on wall.Powder charge casing bottom
Portion designs the switch for drawing off explosive, it is made of baffle 13, rotating bar 12, support rod 14, draught line 3, powder charge casing bottom
Portion's design is there are four hole, two holes that rotating bar passes through, and support rod passes through remaining two hole, pass through two of support rod
Hole axle will be higher than upwards support rod lower than two holes that rotating bar passes through, general rotating bar centerline axis upwards, the two difference
The Weir Plate Thickness that height is 1/2 guarantees that baffle is in level under the action of support rod in this way.Rotating bar is parallel with support rod.Gear
One end of plate is fixedly connected with rotating bar, and the joint angle of baffle and rotating bar is at 90 degree, in order to mitigate overall weight, the width of baffle
Degree can reduce, as long as guaranteeing that the center of powder stick can be fallen on baffle.The diameter of powder charge casing is D, and the width of baffle is
0.2-0.9D。
The length of rotating bar, which should ensure that, deviates center even if baffle, and rotating bar is not also detached from hole, can also be by rotating bar
Both ends carry out bending limit.Support rod is located at the lower section of baffle, and baffle is made to be maintained at powder charge casing bottom, plays support explosive cartridge and makees
With to realize the purpose for sending explosive, one end connection of draught line and support rod.Powder charge casing is hung in and is bored into certain position,
Firmly Traction line opens baffle, and explosive drops out, and extracts powder charge casing, carries out next group of powder charge.
