Description
Technical field
The utility model is related to one kind protecting opening arrangement for mine forward direction deep blasting hole.
Background technology
Surface mine give a farfetched interpretation deep blasting hole when, have certain thickness pine quarrel or the reasons such as lithology detrition for ground surface,
Blasthole quality is influenced, one-tenth porosity is low.It is mainly shown as that perforation procedure or pore-forming guard period aperture are caved in, needs to clear up again,
It is cumbersome, and often therefore blasthole is caused to be scrapped.Dew adopts positive blasthole and has two kinds of straight hole and inclined hole, for improve conscientiously blasthole at
Porosity needs to develop a kind of retaining device adapting to different type blasthole.
Utility model content
The problem of the utility model exists for the above-mentioned prior art makes improvement, and guard aperture cylinder is used in earth's surface loose media section
Body ensures that aperture is complete, i.e., the technical problem to be solved by the utility model is to provide one kind being used for mine forward direction deep blasting hole guard aperture
Mouth device, it is simple in structure, it is easy to use.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：One kind is protected for mine forward direction deep blasting hole
Opening arrangement, including a cylinder, cylinder lateral wall top are evenly equipped with several axially disposed guide rails, on the guide rail
It is provided with the sliding block being moved along it, universal spherical joint is provided on the sliding block, fixed plate is connected on the universal spherical joint.
Further, the both ends of the guide rail are both provided with the plug that anti-limited slip block is detached from.
Further, it is provided with mounting hole in the fixed plate, plug in pricker is provided in the mounting hole.
Further, it is provided with clamping screw on the sliding block.
Compared with prior art, the utility model has the advantages that：The present apparatus can be applicable in simultaneously straight blasthole and tiltedly
Blasthole, it is simple in structure, it is easy to use.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the organigram of the use state of straight blasthole in the utility model embodiment.
Fig. 2 is the organigram of the use state of oblique blasthole in the utility model embodiment.
Fig. 3 is the construction diagrammatic top view of the utility model embodiment.
In figure：1- cylinders, 2- guide rails, 21- plugs, 3- sliding blocks, 4- fixed plates, 41- mounting holes, 5- plug in pricker.
Specific implementation mode
Embodiment one：As shown in Figures 1 to 3, a kind of to protect opening arrangement, including a cylinder 1, institute for mine forward direction deep blasting hole
It states cylinder lateral wall top and is evenly equipped with several axially disposed guide rails 2, the sliding block being moved along it is provided on the guide rail
3, universal spherical joint is provided on the sliding block, and fixed plate 4 is connected on the universal spherical joint.
In the present embodiment, the both ends of the guide rail are both provided with the plug 21 that anti-limited slip block is detached from.
In the present embodiment, it is provided with mounting hole 41 in the fixed plate, plug in pricker 5 is provided in the mounting hole.
In the present embodiment, it is provided with clamping screw on the sliding block, is not shown in figure.
In use, either straight blasthole or oblique blasthole, blasthole is filled in by cylinder, because of the presence of universal spherical joint, fixed plate
Fixed plate can be kept concordant with ground always with angle-adjustable, then plug in pricker is inserted into and is fastened, clamping screw is tightened, fixed
Sliding block is thus avoided that blasthole is caved in.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
