Flat sleeve is fixed on the upper and lower ends of proof rubber belt by rivet, and one is respectively provided with left and right sides of the proof rubber belt
Link and row's snak link are arranged, the buffer spring fixed seat is welded on back-moving spring and flattened on the outer wall of sleeve, and buffering elastic
Buffer spring is installed, one end of the buffer spring is connected with buffer spring fixed plate in the inner chamber of spring fixed seat.
Preferably, the snak link is used for being buckled on link, and link and snak link are directly pressed when whole device produces
On proof rubber belt.
Preferably, the back-moving spring is hung on the bar-mat reinforcement of Rock Workings Support.
Preferably, described when entirely preventing that collapsing device hangs in supporting, buffer spring fixed plate is pressed in the steel of Rock Workings Support
On supporting surface behind muscle net.
Preferably, the buffer spring and buffer spring fixed seat, buffer spring fixed plate are welding manner annexation.
Compared with prior art, the beneficial effects of the utility model are：The anti-device that collapses of the rock drift blasting is in the left and right sides point
Other design and installation link and snak link, can be used for by it is more than two panels this it is anti-collapse device and be overlapped, so as to realize basis
The size of different protection domains carries out selective protection, and is mounted with the upper and lower ends face Position Design of the device with slow
The buffer spring fixed plate of spring is rushed, when the device is hung on protection network, buffer spring fixed plate is just after protection network
The wall in face, in detonation when there is slungshot to pound to the device, buffer spring fixed plate just presses to wall and served to whole device
Cushioning effect, realize to the greatest extent and the buffer itself of the device protected, it is more existing it is anti-collapse device, the device not only has protection
Facility and protection but also have autoprotection function at branch protective function, substantially increase service life.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：A kind of rock drift blasting is anti-to collapse device, including tenses
Spring 1, back-moving spring flatten sleeve 2, proof rubber belt 3, link 4, snak link 5, buffer spring fixed seat 6, buffer spring
Fixed plate 7, buffer spring 8 and rivet 9, the one end of back-moving spring 1 are welded in the inner chamber that back-moving spring flattens sleeve 2, and are tensed
Spring flattens the upper and lower ends that sleeve 2 is fixed on proof rubber belt 3 by rivet 9, and proof rubber belt 3 is each side
Provided with row's link 4 and row's snak link 5, buffer spring fixed seat 6 is welded on back-moving spring and flattened on the outer wall of sleeve 2, and
Buffer spring 8 is installed, one end of buffer spring 8 is connected with buffer spring fixed plate 7 in the inner chamber of buffer spring fixed seat 6.
In above-described embodiment, specifically, snak link 5 is used for being buckled on link 4, and link 4 and snak link 5 are in whole device
Directly bear against during production on proof rubber belt 3, when needing to increase pretective acreage, directly can be carried out with the standby device
Connect by the way that snak link 5 is relative with link 4, in order to ensure that snak link 5 and the stability maintenance of link 4 will not fall off, therefore spring
Button 5 and link 4 are directly born against on proof rubber belt 3 when whole device produces to improve fastness；
In above-described embodiment, specifically, back-moving spring 1 is hung on the bar-mat reinforcement of Rock Workings Support, realize to Rock Workings Support
The protection of bar-mat reinforcement, prevent that slungshot particle causes the phenomenon that breaks to bar-mat reinforcement during rock drift blasting；
In above-described embodiment, specifically, when entirely preventing that collapsing device hangs in supporting, buffer spring fixed plate 7 is pressed in rock
On supporting surface behind the bar-mat reinforcement of lane supporting, buffer spring fixed plate 7 passes through the buffer spring 8 in buffer spring fixed seat 6
Another serves cushioning effect, when slungshot is pounded to proof rubber belt, while being shielded to supporting or reinforcing bar,
Also preferably it can prevent that collapse device plays buffer protection function again to whole simultaneously.
In above-described embodiment, specifically, buffer spring 8 is welding with buffer spring fixed seat 6, buffer spring fixed plate 7
Mode annexation, three, which realizes, goes completely into one, and durable anti-damage performance is improved.
Operation principle：The rock drift blasting is anti-to collapse device, it is possible to achieve to connection function, according to the Rock Workings Support of required protection
Area is carried out carrying out the device docking increase, and the row's snak link 5 for specially showing slightly prominent on the right side of is hung in link 4, real
Now dock, in order to increase the elasticity of whole device, whole device upper and lower ends face design and installation with buffer spring 8
Buffer spring fixed plate 7 and buffering spring fixed seat 8, whole device is hung over to the steel of rock gangway protection supporting by back-moving spring 1
Muscle is online, and the contact surface pressed to behind bar-mat reinforcement that spring dead plate 7 is tried one's best, and is pounded when there is slungshot caused by explosion to protection
When on balata belt 3, proof rubber belt 3 serves the protective effect of isolation slungshot, and spring dead plate 7 presses to contact surface
Buffer spring 8 is driven to produce elastic buffer effect, another serves buffer protection function, and also plays one in itself to device
Fixed protective effect.
