Description
Technical field
The present invention relates to blasting gear field, more particularly to a kind of rock blasting hole measurement bar.
Background technology
Blasting work is very important for mine, and it directly affects the cost of mining, concerns mining profit
Just.Many blast holes are bored before explosion on blasting face, explosive is loaded in this some holes, then implements explosion, quick-fried
Often because the depth for each blast hole for implementing explosion simultaneously is inconsistent in broken implementation, so that the face formed after explosion is not same
In one plane, which adds the cost of mining.
In summary, for the defect of prior art, it is accordingly required in particular to a kind of rock blasting hole measurement bar, thus solve with
On the problem of mention.
The content of the invention
There is provided a kind of rock blasting hole measurement bar in order to solve problem of the prior art by the present invention.
In order to solve the above technical problems, one aspect of the present invention is：A kind of rock blasting hole measurement bar,
Including the upper back-up ring for covering rock blasting hole, the center of upper back-up ring is provided with first through hole, first through hole provided with use
In the measurement bar of measurement explosion hole depth, measurement bar, which is provided with, to be used to prevent the lower back-up ring of measurement bar sideslip, lower back-up ring and upper gear
It is fixedly connected between circle by multiple bracing pieces, the side of the measurement bar is provided with a groove from top to bottom, and the side of groove is set
There is the spiral shell for being used to fasten measurement bar for being provided with the baffle plate for being fixedly connected with upper back-up ring, baffle plate and being used for using cooperatively with groove
Silk.
In a preferred embodiment of the present invention, the diameter of the lower back-up ring is 1/2nd of upper back-up ring diameter.
In a preferred embodiment of the present invention, the lower end of the measurement bar is taper.
In a preferred embodiment of the present invention, the inner side of the bracing piece is provided with the bulb for illuminating, so can be with
Facilitate reading.
The present invention compared with prior art, advantageously, can fast and accurately measure the depth of blast hole.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in figure 1, a kind of rock blasting hole measurement bar of the present invention, including for covering rock blasting hole
Upper back-up ring 1, the center of upper back-up ring 1 is provided with the measurement for being provided with first through hole, first through hole and being used for measuring explosion hole depth
Bar 2, measurement bar 2, which is provided with, to be used to prevent the lower back-up ring 3 of the sideslip of measurement bar 2, is added between lower back-up ring 3 and upper back-up ring 1 by multiple
Strong bar 4 is fixedly connected, and the side of the measurement bar 2 is provided with a groove 5 from top to bottom, and the side of groove 5, which is provided with, to be used for and upper gear
The screw 7 for being used to fasten measurement bar 2 for being used for using cooperatively with groove 5 is provided with the baffle plate 6 that circle 1 is fixedly connected, baffle plate 6.
By a preferred embodiment of the present invention, the diameter of the lower back-up ring 3 is 1/2nd of the upper diameter of back-up ring 1.
By a preferred embodiment of the present invention, the lower end of the measurement bar 2 is taper.
By a preferred embodiment of the present invention, the inner side of the bracing piece 4 is provided with the bulb 8 for illuminating, so can be with
Facilitate reading.
The present invention is during use, first by upper back-up ring and a clogging blast hole of plug of lower block circle formation,
Then measurement bar is promoted, the bottom of measurement bar is contacted with the inner bottom surface of blast hole, then using screw locking measurement bar, then
Measurement bar reading is extracted, the depth of blast hole so just can be easily measured very much, this is a kind of new technical scheme, is easy to
Promote the use of.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
