Description

A kind of blasting flyrock protective device

Technical field

The utility model is related to a kind of blasting flyrock protective devices.

Background technology

With the development of China's economy and technology, more and more blasting engineerings enter people’s lives and production district Domain due to the uncertainty of blasting flyrock and the complexity of blasting environment, makes ambient enviroment greatly be endangered, the anti-explosion of tradition Slungshot device is all shorter, it is impossible to ensure that slungshot is all blocked, and a large amount of flying dust are had during explosion, device is subject to impact force Also it is very big, it is necessary to ensure that device is not toppled over.

The content of the invention

To achieve these goals, the utility model employs following technical solution：The device is three layers, interlayer, that is, bullet Property substance, elastic material both sides are covered and are fixed by wire netting, and device is divided by hinge（Hinge）Two parts up and down of connection, dress Putting can fold, be unfolded, and more convenient movement after folding increases device height, on device after expansion by telescopic rod support Two layers of water covering can be hung, reduces the depositing dust after explosion and the impact to device, considerably increases the service life of device.

The fixing device for keeping out blasting impact is equipped with below device, which is located at the lower section both sides of protective device, It is made of rotatable telescopic rod, block and a ground nail, telescopic rod is located among lower device, prevents that impacting ambassador's device inclines .

Fig. 3 is the utility model fixture structure schematic diagram.

In figure：1 first telescopic rod；2 wire nettings；3 elastic materials；4 hinges（Hinge）；5 links；6 water bags；7 ropes；8 Two telescopic rods；9 ground nails；10 blocks.

Specific embodiment

As shown in Figure 1 to Figure 3, the blasting flyrock protective device in present embodiment, it is including three layers, i.e., middle spring Substance 3 is covered and fixed by the wire netting 2 of both sides, and device is divide into upper part and lower part, by hinge（Hinge）4 connections, so device It can fold, 8 one side of the second telescopic rod is fixed on above device, when the apparatus is switched on, can be stretched the second telescopic rod 8, be propped up Lower section device supports the top device, to increase device height, with link 5 on the device of top, can rope 7 be tied up to link On, water bag 6 is then fastened, edge link can connect other explosion-protection equipments, can also be on the wire netting 2 of device on the top Upper rope 7 then plus water bag 6, makes two layers of water bag 6 of suspension in front of device, carrys out protective device.

Specifically, fixing device is equipped with below device, by 9 groups of rotatable first telescopic rod 1, block 10 and ground nail Into, the first telescopic rod 1 in the centre of lower section device, 30 degree can be rotated around block 10,10 bottom of the first telescopic rod is sharper It is sharp, ground is may be inserted into, ground nail 10 is located at the corner of lower section device, can also be inserted into ground, prevents that impacting ambassador's device inclines .

Claims

1. a kind of blasting flyrock protective device, it is characterised in that：Device is three layers, intermediate for elastic material, elastic material both sides It is covered by wire netting and is fixed, device, which is divided into, can be folded, be unfolded by hinged two parts, device up and down, after folding more Add and be moved easily, increase device height by two telescopic rod support top devices after expansion, to stop higher slungshot, filling Link has been put, water covering can be hung, one layer of water covering can also be hung on wire netting, has reduced depositing dust and slungshot after explosion Impact to device.

2. a kind of blasting flyrock protective device according to claim 1, it is characterised in that：Also have below device and keep out explosion The fixing device of impact, the fixing device are located at the lower section of protective device, by rotatable first telescopic rod, block and ground nail group Into telescopic rod is located among lower device, prevents that impacting ambassador's device topples over.
