Description
Technical field
The utility model belongs to the technical field of mining and geotechnical engineering, poly- more particularly to a kind of portable pull
It can pack.
Background technology
Highwall explosion in large-scale hydroelectric project slope excavating, the Blasting In Geotechnical in urban construction or excavation of foundation pit are quick-fried
The production resettlement etc. of broken, Near slope blasting in large surface mine exploitation and certain non-metal mines has some common prescriptions,
I.e.：Mitigation explosive is bad to highwall slope, protects the integrity of highwall, and then reduces the maintenance cost of side slope；Reduce attenuation of seismic waves
Intensity, the flutter failure for mitigating explosion side slope or Adjacent Buildings mitigate the excessive crushing around blasthole.To realize that these are wanted
It asks, often using Uncoincided charge technology in engineering, and Uncoincided charge is divided into axial do not couple and is not coupled with circumferential, axis
It is realized by using axial powder charge spacer to Uncoincided charge, and has been applied in explosion.And circumferential direction does not couple
It is realized by reducing cartridge size, but circumferential position of the powder column in blasthole is uncertain, is easy to abut blasthole inner wall one
Side and there is larger airspace in the other side, although this free style structure is met the requirements when calculating the not coefficient of coup, no
It can realize the effective protection of highwall and the uniform reduction of seismic wave.
Invention content
The purpose of this utility model is to provide a kind of portable pull Concentrated charges, solve since powder column is in blasthole
Side hole wall destroys serious problem in the explosion that circumferential position is uncertain and brings, and can more turn the energy of detonation gas
It is melted into the kinetic energy of energy-gathering jetting, effective controlled fracturing blasting direction prevents the formation and extension in other cracks, reduces irregularity degree, carries
High yield.
The purpose of this utility model is realized by following technical proposals：
A kind of portable pull Concentrated charge of the utility model by chassis, one group of casing being connected with this chassis and point
One group of fixed ring not being correspondingly sleeved on this group of casing is formed, the diameter dimension of described one group of casing from bottom to top according to
Secondary to successively decrease and overlapped socket between adjacent casing, the diameter dimension of one group of fixed ring is with described sleeve pipe diameter dimension
Change successively and match with the casing diameter size that it socket-connects, the lower part of described sleeve pipe is equipped with rebound snap-fastener, described sleeve pipe
Top be equipped with and the button hole that is mutually clamped of rebound snap-fastener.
The section outer contour shape of described sleeve pipe is made of hyperbola and the intersection of Symmetrical Circular Arc line, the rebound snap-fastener
It is each provided at button hole on the circular arc line outer surface.
The casing is made of PVC pipe, and the rebound snap-fastener uses moulded of plastics material button, described
Fixed ring is made of cystosepiment.
The advantages of the utility model：
1）The utility model adds fixed ring and sockets for collecting energy enables in quantity set, can more convert the energy of detonation gas
At the kinetic energy of energy-gathering jetting, explosive is saved；It is split along what joint-cutting extended in the case of joint, stratification development and stress of primary rock complexity
When seam meets with primary fracture, detonation pressure is higher, and effluxvelocity is bigger, and cutting effect is better；Effective controlled fracturing blasting direction, prevents
The only formation and extension in other cracks reduces irregularity degree, improves lumber recovery；
2）The utility model can be used for the cutting of the materials such as marble, granite；By controlling the direction of cumulative shooting flow, greatly
Reduce the shock wave to country rock, earthquake wave action greatly；Increase presplitting pitch of holes, reduce drilling expense and labor intensity, improves
Efficiency；Telescopic length is convenient for carrying.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the vertical view of the utility model Fig. 1.
Specific implementation mode
As shown in Figure 1, 2, a kind of portable pull Concentrated charge of the utility model is connected by chassis 1 with this chassis
One group of casing 2 and one group of fixed ring 3 being correspondingly sleeved on respectively on this group of casing formed, described one group of casing it is straight
Diameter size is successively decreased successively from bottom to top and overlapped socket between adjacent casing, the diameter dimension of one group of fixed ring with
Described sleeve pipe diameter dimension changes and matches with the casing diameter size that it socket-connects successively, and the lower part of described sleeve pipe is equipped with
Spring back snap-fastener 4, the top of described sleeve pipe is equipped with the button hole 5 being mutually clamped with the rebound snap-fastener, in big between casing when carrying
Part surface overlap condition, rebound snap-fastener 4, which is pressed into pipe sleeve outer surface, not to work, and one group of casing overall length dimension is minimum,
In use, stretching each casing, rebound 4 automatic rebounding of snap-fastener is allowed to enter in the button hole of adjacent casing, one group of casing total length ruler
Very little maximum, explosive payload are most.Fixed ring 3, which can need to choose by correspondingly-sized according to scene, to be set with.Above-mentioned pipe pipe is nested, with reality
Now axial cumulative and Uncoincided charge and simple carrying, and multistage combination can be designed according to blast hole depth, it is used between multistage
Plastic button is socketed.
Pack size is just adjusted according to design requirement in this way to realize the dress of the different pore size cumulative circumferential direction not coefficient of coup
Medicine；It is supported by fixed ring between Concentrated charge and blasthole, not only can guarantee position of the spacer in blasthole, but also can be accurately positioned
The direction of energy-gathering jetting；It is socketed using plastic snapper between multistage pack, the overall length of pack is adjusted according to blast hole depth.
The section outer contour shape of described sleeve pipe is made of hyperbola 6 and two intersections of Symmetrical Circular Arc line 7, and described returns
It plays snap-fastener and button hole is each provided on the circular arc line outer surface.Hyperbola outer surface forms sockets for collecting energy with fixed ring inner surface can
The direction for controlling cumulative shooting flow, substantially reduces the shock wave to country rock, earthquake wave action；Increase presplitting pitch of holes, reduces drilling
Expense and labor intensity, improve efficiency；Telescopic length is convenient for carrying.
The casing is made of PVC pipe, and the rebound snap-fastener uses moulded of plastics material button, described
Fixed ring is made of cystosepiment.
