Description
Technical field
The utility model relates to one kind to be used for the oblique blast hole projectile filling positioning device of presplitting.
Background technique
Slope and land slide is the mostly important safety devices of surface mine, whether stability of slope, concerning the normal of entire mine
Production.
Presplit blasting is as a kind of construction method for guaranteeing side slope safety, and the important measures of maintenance stability of slope.Through
Cross presplit blasting, retain that rock mass wall surface is relatively stable, complete, be retained rock mass not by or it is seldom be destroyed, reduce not
It is necessary to backbreak, side slope is controlled to greatest extent and sprays anchor expense, and slope surface appearance is neat.
But the explosion of presplitting blasthole needs not couple spaced loading, i.e., the installation weight spaced apart in blasthole
Not equal explosive, how efficiently, convenient construction operation is at a great problem.So far for this purpose, still lacking a kind of good device
The powder charge for going realization presplitting blasthole, brings very big difficulty to blast working.
Existing way is spaced binds the blasting charge at an upper portion thereof, and used primacord at an upper portion thereof with a bamboo pole or bamboo chip
Blasting charge is connected, this way can frequently result in primacord and disengage with the blasting charge or primacord when backfilling operation
Broken by sandstone, especially for oblique blasthole, explosive can not be located at blasthole hit exactly, skew place, cause demolition effect exist compared with
Big difference.
Utility model content

Art problem is to provide one kind for the oblique blast hole projectile filling positioning device of presplitting, and structure is simple, easy to use.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: one kind is fixed for the oblique blast hole projectile filling of presplitting
Position device, including two halves circular guide, two guide grooves close up after in a circular pipe, for placing primacord in the pipeline, wherein
Several screw holes are evenly equipped with along axial direction on one guide groove side wall, further include multiple explosive boxes for blasting charge, the explosive cassette bottom
Portion is provided with externally threaded screwed pipe, the screwed pipe be screwed on screw hole and be connected inside pipeline, the guide groove inner sidewall
On be provided with guide rail, the semicircle sealing plate moved along guide rail is provided on the guide rail, is provided with and allows among the sealing plate bottom
The semicircle card slot that primacord passes through, each screwed pipe two sides are provided with a sealing plate, so as to constitute a closing by four blocks of sealing plates
Space；More screw rods are bolted on the lateral wall of the guide groove both ends, the screw rod end is hinged with rubber wheel.
Further, the sealer for sealing screw hole is pasted on the guide groove lateral wall.
Further, the protrusion being mutually engaged and groove are respectively arranged on the side wall that two guide grooves fit, the protrusion and
Groove is in oat tail groove structure.
Further, the bayonet being mutually engaged with guide rail is provided at the top of the sealing plate, the bayonet and guide rail are in dovetail groove
Structure.
Further, the card slot radius is less than or equal to primacord radius.
Compared with prior art, the utility model has the following beneficial effects: the present apparatus can ensure that explosive is located in blasthole
The heart, and ensure that contact of the primacord with explosive, primacord is protected, structure is simple, easy to use.
