Abstract
This utility model belongs to perforation plugging field, is specifically related to a kind of four grapple swollen bar depositing dust stopper.Easy play the most inwards during the swelling that this utility model exists to solve existing embrasure plugging device, dust that blasting process produces and toxic gas cannot the effective problems such as reduction, and then provide a kind of four grapple swollen bar depositing dust stopper, including matching used closure body and entity drift, closure body includes the swollen bar of annular of integral type and spherical plug, the swollen bar of annular is hollow structure, the extended end of the swollen bar of annular is provided with the four grapple tail pipes turned up, and the hollow hole flushing type swelling of entity drift is swollen with annular bar coordinates.This utility model utilizes four grapple tail pipes to firmly grasp big gun hole outer wall, prevents stopper play inwards when annular swollen bar driven in by drift；The dress water polo shape plug of stopper termination, can realize cooling, depositing dust, fall concussion of blasting, reduces the purpose that harmful gas produces.
Description
Technical field
This utility model belongs to perforation plugging field, is specifically related to a kind of four grapple swollen bar depositing dust stopper.
Background technology
During blast working, the closure quality in big gun hole can directly affect demolition effect, as explosive range, the response rate of explosive,
Toxic gas ratio etc. after blast, and block quality mainly by stopper structures shape.At present, the stopper of relatively broad utilization
For spalling class, such as patent 201120297739.5 and patent 201420470671.X, but such stopper is during swelling, holds
Easily occur to direction play at the bottom of big gun hole, affect swelling effect.Meanwhile, blasting process can produce dust and toxic gas, and dust is dense
Spending big, one is to affect blow-up point environment, and two is the excessive easy initiation extraneous explosion of dust concentration after blast, there is safety hidden
Suffer from.
Summary of the invention
Easy play the most inwards during the swelling that this utility model exists to solve existing embrasure plugging device, blasting process produces
Raw dust and toxic gas cannot the effective problem such as reduction, and then provide a kind of four grapple swollen bar depositing dust stopper.
This utility model adopts the following technical scheme that
A kind of four grapples swollen bar depositing dust stopper, including matching used closure body and entity drift, blocks body bag
Including the swollen bar of annular of integral type and spherical plug, annular swollen bar is hollow structure, and the extended end of annular swollen bar is provided with to turn up and forms
Four grapple tail pipes, the hollow hole flushing type swelling of entity drift is swollen with annular bar coordinates.
The grapple of described four grapple tail pipes is to be turned up 45 ° by annular swollen bar to be formed.
Described annular is swollen, and bar has elongated precracking along 90 degree of its axis direction interval.
The inverted gun thorn reverse with big gun hole uniformly it is covered with on described annular is swollen bar.
The diameter of described entity drift is more than the hollow hole diameter of annular swollen bar, and the length of entity drift is less than hollow hole
Length.
Described spherical plug is hollow structure, is full of water in plug, and during explosion, aqueous solution flows out and dust and toxic gas
Mixing, reaches depositing dust and neutralizes the purpose of degraded poison.
This utility model has the advantages that
1, swollen bar termination is provided with four grapple tail pipes of eversion type, can firmly grasp big gun hole outer wall, when annular swollen bar driven in by drift
Prevent stopper play inwards, it is ensured that swollen bar can fully swelling；
2, stopper termination is provided with the spherical plug of dress water, and during explosion, aqueous solution flows out and mixes with dust and toxic gas,
Reach cooling, depositing dust, fall concussion of blasting, reduce the purpose that harmful gas produces；And water or air insert big gun hole after realize not coupling
Attach together medicine, can weaken detonation pressure peak value, extend detonation gas action time, improve the capacity usage ratio of explosive charge.
Accompanying drawing explanation
Fig. 1 is the structural representation of closure body；
Fig. 2 is the sectional view of closure body；
Fig. 3 is the structural representation of entity drift；
In figure: 1-tetra-grapple tail pipe, 2-annular swollen bar, 2-1-precracking, the spherical plug of 3-, 4-entity drift.
Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Four grapple described in the utility model swollen bar depositing dust stopper, is mainly made up of four parts.Part I is to play
Fix four grapple parts of this stopper；Part II is swollen bar part；Part III is spherical plug, and plug is internal full
Water；Part IV is entity drift.First three part is structure as a whole.
As shown in Figure 1,3, four grapples swollen bar depositing dust stopper includes four grapple tail pipes 1, annular swollen bar 2, spherical plug 3 He
Entity drift 4.
Four grapple tail pipes 1 are integrated with annular spalling bar 2, and four grapples turn up 45 ° and to be formed by extending the swollen bar of the annular.
The effect of four grapples is promptly big gun hole outer wall, prevents stopper play inwards when annular swollen bar driven in by drift, it is ensured that drift energy
Swollen bar swelling is made in pouring annular swollen bar completely.
As in figure 2 it is shown, annular swollen bar 2 is hollow structure, annular swollen bar 2 opens precracking 2-1 every 90 °, and often
Inverted gun thorn uniformly it is covered with on individual swollen bar.When stopper loads big gun hole, drift 4 is knocked in swollen bar 2, makes swollen bar spalling, by ring
Shape inverted gun thorn thrusts big gun hole inwall, reaches plugging effect.
Spherical plug 3 can be broken up by gas atmosphere when explosion happens, and the aqueous solution in plug flows out and reaches with mix dust
To the mesh ground of depositing dust, the part toxic gas at closure after blast is also had simultaneously and necessarily neutralize Degradation.
