Abstract
The utility model provides a prestress blasthole protector, which is characterized in that the blasthole protector is of a cylindrical thin shell structure of which the diameter is slightly larger than the diameter of a blasthole; an opening is formed in one axial side of the blasthole protector; a detonator nonel line outlet and a lifting hand button are arranged at the upper part of the blasthole protector; the lower part of the blasthole protector is designed to be an inner holding mode. The prestress blasthole protector is novel in structure, simple in process, strong in suitability for blasthole deformation, good in blasthole protection effect, and capable of effectively solving the blasthole maintenance problems under various climate conditions, so the scrapping rate of the blasthole is reduced, and the misfire detonation safety problem caused by the fact that the detonator nonel is rolled and broken as floating rocks are accumulated at the blasthole during the detonation construction is reduced.
Description
Technical field
The utility model belongs to mining engineering field, particularly a kind of prestressing force big gun hole hole keeper.
Background technology
There is certain thickness scum layer in the big gun hole scope of operation of having worn due to opencut rotary drill, in explosion for the previous period, at strong wind, is easy to cause big gun hole aperture float stone and rock slag muck side under heavy rain effect, forms useless hole.In addition, in the time that blast charging landfill is constructed, workmen and implement operation easily cause the scum layer disturbance of big gun hole, cause aperture, big gun hole float stone heap side, and detonator detonator is threatened safely, cause and miss-fire.
Summary of the invention
The purpose of this utility model is to provide a kind of prestressing force big gun hole hole keeper, for aperture, top, big gun hole scum layer provides effective protection, improve its stability, solve at strong wind on the one hand, under heavy rain adverse weather condition, big gun hole subsides and piles side problem, reduce the useless porosity in big gun hole, reduce rotary drill and process the cost in useless hole; Be to solve in the time that blast charging landfill is constructed on the other hand, operating personnel and implement, to the scum layer disturbance of big gun hole, cause aperture float stone heap side, the safety problem of miss-firing that the detonator detonator that breaks causes.
The purpose of this utility model realizes by following technical proposals:
A kind of prestressing force big gun hole hole keeper, is characterized in that this hole keeper is the cylindrical shape thin walled shell structure that diameter is a bit larger tham blasthole diameter and an axial side opening, and top is provided with detonator detonator line outlet and lifts hand button, and bottom is designed to interior receipts form.
The angle [alpha] of a described axial side opening is 65～78 °, and both sides are bead designs, and in bottom, receiving angle beta is 12～18 °.
The material of described cylindrical shape thin walled shell is engineering plastics.
The utility model novel structure, technique is simple, to big gun bore deformation strong adaptability, big gun hole protection effect is good, can effectively solve big gun hole maintenance issues under all kinds of weather conditions, float stone heap side in big gun hole while reducing the useless porosity in big gun hole and blast working, the safety problem of miss-firing that the detonator detonator that breaks causes.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-cylindrical shape thin walled shell; 2-lift hand button; 3-detonator detonator line outlet; 4-opening; 5-bottom.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model is applicable to the effective protection for surface mine borehole in all kinds of weather conditions and blast working situation.A kind of prestressing force big gun hole hole keeper, it is characterized in that this hole keeper is engineering plastics cylindrical shape thin walled shell 1 structure that diameter is a bit larger tham blasthole diameter and an axial side opening 4, top is provided with detonator detonator line outlet 3 and lifts attacker 2, and bottom 5 is designed to interior receipts form.Take the blasthole diameter of giving a farfetched interpretation of surface mine rotary drill as 250mm is as example, a long 1050mm of the utility model design, diameter 300mm, engineering plastics cylindrical shape thin walled shell 1 structure of an axial side opening 4, opening 4 angle [alpha] are 72 °.Under the extruding of operating personnel's both hands external force; opening 4 closures, the cylinder that formation diameter is 240mm, due to elastic deformation occurring; the inner prestressing force that forms; pack top, big gun hole into, discharge after external force, by enclosure interior stress, blasthole hole wall is formed to expansionary force; play the protective effect to scum layer hole wall; cylindrical shape thin walled shell 1 bottom 5 is designed to interior receipts form, and interior receipts angle beta is 15 °, is convenient to put into big gun hole.While putting into big gun hole, cylindrical shape thin walled shell 1 exceeds peripheral ground 50mm, avoids rock slag, rainwater to pour in down a chimney.At the bottom of the enough frictional force being produced by expansionary force in addition guarantees the unlikely hole of dropping of hole keeper.When being subject to the factors such as rainwater immersion when big gun hole and causing hole wall to increase hole keeper compression, opening 4 dwindles, and provides tension force progressively to increase.Cylindrical shape thin walled shell 1 opening 4 places are designed to crimping housing changing of the relative positions while avoiding closure, and in the time that opening is closed, hole keeper body construction provides extra bearing capacity.
The upper design of this structure detonator detonator line outlet 3, have protection detonating cord effect, top has also been designed and has been lifted attacker 2, is convenient to installation and the recovery of hole keeper.
Claims (3)
1. a prestressing force big gun hole hole keeper, is characterized in that this hole keeper is the cylindrical shape thin walled shell structure that diameter is a bit larger tham blasthole diameter and an axial side opening, and top is provided with detonator detonator line outlet and lifts hand button, and bottom is designed to interior receipts form.
2. a kind of prestressing force big gun according to claim 1 hole hole keeper, the angle [alpha] that it is characterized in that an axial side opening is 65～78 °, and both sides are bead designs, and in bottom, receiving angle beta is 12～18 °.
