Abstract
The utility model discloses a plug for borehole, including stopper shell (1), stopper chamber (2), cock body (3), its characterized in that stopper shell (1) is the elastomer, and fills in shell (1) both ends symmetry, and the part of the crooked parcel in stopper shell (1) both ends forms the regional stopper chamber (2) that forms in space of cock body (3), stopper shell (1) lower part. The utility model discloses it is simple and convenient practical, low cost. After putting into the big gun hole with plug for borehole, stopper shell (1) can according to big gun hole diameter automatic crooked and with big gun hole interference fit, tightly attach on the big gun pore wall, accomplish the decurrent downthehole explosive in shutoff, especially big gun hole drill way to downthehole explosive, act on more obviously.
Description
Technical field
The utility model belongs to blasting material field, relates to a kind of plug for borehole.
Background technology
When on ore deposit, down-hole or subway tunnel carry out blast working, when aperture, big gun hole is downward, adopt the explosive of coupled mode filling very easily to drop out big gun hole, cause big gun hole can not effective fragmentation, cause and owe to dig or other adverse consequences, therefore measure must be adopted effectively to be got lodged in big gun hole by explosive.Meanwhile, for the big gun hole of Discontinuous charge, need explosive to be fixed on different position, big gun hole.Existing technology is: a kind of hat plug for borehole, is provided with cone, flexible fixed-wing, fixing hole, during use, uses urging action bar, hat plug for borehole is put into big gun hole, makes flexible fixed-wing fix hat plug for borehole.But in engineering reality, due to reasons such as hat plug for borehole complicated operation, convenience differences, cannot extensive use.Therefore, a kind of more simple and practical plug for borehole is needed.
Summary of the invention
The purpose of this utility model is for problems such as existing hat plug for borehole complicated operation, convenience differences, provides a kind of device of convenient practicality.
The purpose of this utility model realizes by following technical proposal:
A kind of plug for borehole, comprises plug shell, plug chamber, cock body, it is characterized in that plug shell is elastomer, and plug shell two ends is symmetrical, and the part of plug shell bending two ends parcel forms cock body, and the void area of plug shell bottom forms plug chamber.
Above-mentioned a kind of plug for borehole, it is characterized in that: the length of described plug shell, in the scope of 15mm ~ 150mm, is not put into the plug shell width before big gun hole and is greater than blasthole diameter, width can diminish according to blasthole diameter is bending, after putting into big gun hole, plug shell and big gun hole interference fit.
Above-mentioned a kind of plug for borehole, is characterized in that: the material of described plug shell is plastics, cardboard or rubber.
Above-mentioned a kind of plug for borehole, is characterized in that: the described width of plug chamber after plug for borehole puts into big gun hole is greater than the diameter of the payment to a porter of big gun hole detonator afterbody or the detonator of detonator afterbody.
Above-mentioned a kind of plug for borehole, is characterized in that: the shape of cross section that described plug chamber and cock body form is for oval or circular.
Above-mentioned a kind of plug for borehole, is characterized in that: described cock body is hollow or solid.
Accompanying drawing explanation
Fig. 1 is plug chamber of the present utility model is solid structural representation.
Fig. 2 is plug chamber of the present utility model is hollow structural representation.
In figure, 1, plug shell; 2, chamber is filled in; 3, cock body; L, plug shell length; W, plug shell width; B, plug chamber width.
Detailed description of the invention
Be below specific embodiment of the utility model, by reference to the accompanying drawings, the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.In the present embodiment, blasthole diameter is 42mm, and explosive need be fixed on bottom big gun hole, and detonator used is plastic detonating tube detonator.
A kind of plug for borehole, comprises plug shell 1, plug chamber 2, cock body 3, it is characterized in that filling in shell 1
The length L of plug shell 1 is 80mm, and not putting into plug shell 1 width W before big gun hole and be greater than blasthole diameter, is 52mm, and width W can be varied down to 35mm according to blasthole diameter is bending, puts into big gun hole, and plug shell 1 width becomes 42mm, makes plug for borehole and big gun hole interference fit.The material of plug shell 1 is elastomeric butadiene-styrene rubber.
The plug width b of chamber 2 after plug for borehole puts into big gun hole is greater than the diameter of the payment to a porter of big gun hole detonator afterbody or the detonator of detonator afterbody, is 8mm.The shape of cross section that plug chamber 2 and cock body 3 form is oval.Cock body 3 is solid.
During use, first bending plug shell 1, makes width W become 35mm, puts into big gun hole, because plug shell 1 is elastomer, returns to the width 42mm identical with blasthole diameter; Make the afterbody detonator of plastic detonating tube detonator within plug chamber 2, protection detonator is not extruded wearing and tearing; Tamper is used to be shifted onto by plug for borehole bottom big gun hole, adjacent explosive.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Claims (3)
