Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of rock drift blasting is anti-to collapse device, including baffle 1, leads
To bar 2, connection leg 3, spring 4, baffle-box 5, fixed plate 6, buffer board 7, mounting ring 8, exhaust outlet 9, surge chamber 10, air inlet 11
With through-hole 12, buffer board 7 is installed on the bottom side of baffle 1, guide rod 2 is mounted in the top side face of 5 outer wall of baffle-box, connection
Mounting ring 8 is installed, the both ends of spring 4 are mounted on mounting ring 8, and the top side face in fixed plate 6 is arranged in baffle-box 5, fixed on leg 3
Through-hole 12 is provided on plate 6, exhaust outlet 9 is arranged in the top side face of baffle-box 5, and the inside phase of exhaust outlet 9 and surge chamber 10
Logical, air inlet 11 is arranged on the bottom side of fixed plate 6, and air inlet 11 is communicated with the inside of surge chamber 10, and surge chamber 10 is set
It sets in the inside of baffle-box 5.
In above-described embodiment, specifically, through-hole 12 is provided on baffle 1, and baffle 1 is mounted on guide rod by through-hole 12
On 2, baffle 1 is moved by through-hole 12 on guide rod 2；
In above-described embodiment, specifically, spring 4 can be dismantled from mounting ring 8, and spring 4 is provided with symmetrical two
It is a, it is convenient for changing different springs, symmetrical spring makes baffle 1 always vertically on guide rod 2；
In above-described embodiment, specifically, the bottom side of buffer board 7 is set as arc surface, and buffer board 7 can be dismantled, and delay
Punching 7 is made of yielding rubber, and the arc surface of buffer board 7 can effectively guide dispersion explosion air-flow, and yielding rubber can hinder
Only explosion spoil bounces；
In above-described embodiment, specifically, baffle-box 5 is structure as a whole with the setting of fixed plate 6, convenient for baffle-box 5 and fix
The installation of plate 6 is fixed.
Operation principle：When collapsing device using the rock drift blasting is anti-, need to prevent that collapsing device has one to entire rock drift blasting first
Understanding in a structure can be used more easily when in use, make the axis and blasting hole axis of air inlet 11
Alignment is fixed fixed plate 6 by the through-hole 12 in fixed plate 6 with pin, is installed according to the intensity size of rendrock different
Spring 4 air-flow for being mingled with spoil is sprayed in blasting hole, air-flow is through air inlet 11 after explosive initiation in blasting hole
Into surge chamber 10, surge chamber 10 is bigger than 11 volume of air inlet, and the inside post consumption that air-flow enters surge chamber 10 falls a large amount of move
Can, air-flow is gone out through exhaust outlet 9 later, in gas shock to buffer board 7 after, the kinetic energy of air-flow is applied to the bottom side of buffer board 7
On face, the spoil in air-flow impinges upon on the bottom side of buffer board 7, and the kinetic energy of spoil is transmitted to buffer board 7, buffer board 7 at this time
It transfers force on baffle 1, is moved after 1 stress of baffle, 4 stress of spring stretches, and so that baffle 1 is slowed down and moves, at this time air velocity
It substantially reduces, the kinetic energy of spoil is depleted in air-flow, no longer has destructiveness, prevents collapsing operation to realize.
In conclusion although the present invention is described in detail referring to the foregoing embodiments, for the technology of this field
It, still can be with technical scheme described in the above embodiments is modified, or to which part technology for personnel
Feature carries out equivalent replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on, and
It should be included within protection scope of the present invention.
