Abstract

The utility model discloses a popping rock blasting protector. The device is the four layers, and the intermediate level is the rubber big gun by the stratum reticulare, and the big gun is covered and be fixed with the wire netting by stratum reticulare both sides, the outmost water drum layer that is, and the water drum can be replaced, three connecting hole or coupling hook are laid respectively to device outside periphery, can realize the polylith concatenation, the device outside sets up the convenient transport of handle all around. The utility model discloses strengthened the performance of preventing popping rock big gun quilt, the high -pressure gas's that is favorable to producing the blasting release and the popping rock that produces the blasting cushion effectively, and the main material big gun is adopted car junked tire or old and useless conveyer belt to make, and external water drum layer receives high -pressure gas or the popping rock collision formation water curtain that breaks promptly, helps the dust fall after the blasting, embodies green's idea.

Description

A kind of Novel explosion flyrock protection device

Technical field

This utility model relates to a kind of Novel explosion flyrock protection device, is particularly well-suited to the flyrock protection of surface blasting, big gun quilt and external water covering and can slow down the harm to surrounding of blasting flyrock and flying dust in General Explosive.

Background technology

In recent years, along with the development of China's economic and technical, increasing blasting engineering enters into the life of people and produces region, and the blasting flyrock brought owing to blasting environment becomes increasingly complex, dust and noise nuisance are also increasingly severe. According to statistics blasting flyrock public hazards oneself through becoming one of latent defect reason the most serious in blasting engineering, the casualties that causes due to blasting flyrock, damage Factory Building and house, smash the demolition accidents such as machinery equipment and take place frequently.

The reason causing blasting flyrock has a lot, including to being understood not by the performance of quick-fried medium and construction features, the layout of borehole and the direction of jewel hole, that the blasting parameter such as the position of minimum burden and size, the height of explosive specific charge, charge constitution form selects is improper, construction quality not up to requiring, covering position not to or cladding thickness is inadequate etc. can produce blasting flyrock.

In common Control Blasting process, the means that the blasting flyrock that covered protection is maximally efficient produces, adopt blasting flyrock preventer carry out covered protection quick-fried point is carried out effective over, the speed being possible not only to slow down the slungshot that explosion produces can also discharge and buffer shooting pressure-air shock wave to a great extent.

This blasting flyrock preventer adopts the big gun quilt that automobile waste old tire or waste and old conveyer belt are made, and there is certain intensity and toughness, outside parcel wire gauze firmly connects, and can produce suitable deformation after being impacted, and the gases at high pressure that explosion produces can also be effectively evacuated in the space of big gun quilt. This device is possible not only to repeatedly reuse, moreover it is possible to making full use of automobile waste old tire and waste and old conveyer belt to reduce its harm to environment, external water covering effectively can also play the effect of environmental protection by depositing dust.

Summary of the invention

Apparatus of the present invention can overcome that existing device service life is short, cost is high and flyrock protection poor effect drawback, be a kind of novel four-layer structure slungshot blasting protection device.

This device is four-layer structure, interior three layers is big gun tegillum and both sides iron wire stratum reticulare, big gun all leaves bigger space between two crossing rubber any in stratum reticulare, it is neat that outermost layer causes edge with the lock seaming of common rubber strip, big gun can be fixed with bolt by surrounding and center, big gun is penetrated steel wire by surrounding boring and fixes, and big gun is all realized being reliably connected with two sides wire gauze. Outermost layer is water covering, and it is detachable that water bag is attached on the draw-in groove of outer layer wire gauze, is subject to impulsive force water bag and rupturable at device outer layer generation water curtain dust fall.

This device is square, and surrounding arranges supporting hole or hook, can connect into by requirement of engineering and need size, arrange handle in outermost layer surrounding, and two to three adults can carry.

The outer layer water bag of this device is attached on the wire gauze of outer layer covering gun by space, and water bag adopts disposable PVC plastic thin-film material, and water bag depends on fixing tabletting and bolt is attached on outside wire gauze.

The advantage of this device is made with being characterized as being employing automobile waste old tire or waste and old conveyer belt etc., makes full use of waste and scrap, cheap and environmental protection; And this kind of blasting protection installation weight is moderate, both can guarantee that and do not produced over-large displacement when being subject to slungshot and gases at high pressure impact, it is also possible to realized two or three adult's carryings; And this device has certain intensity, toughness and bullet to mould retractility, and it is provided with space, it is possible to the high speed slungshot that explosion is produced carries out hindering buffering, and the gases at high pressure that explosion is produced discharge; Outermost layer water covering is arranged in the gap that rubber big gun is spliced, and is subject to water bag meeting breakage when certain gas or slungshot impact, forms one layer of water curtain in whole outside of deivce face, it is possible to reach good depositing dust environmental protection effect. It is reliably connected between two-layer wire gauze and big gun quilt, and arranges handle at outermost layer. This device is square, and character is regular and is easy to splicing.

Detailed description of the invention

For this Novel explosion flyrock protection device of mode layer-by-layer preparation as shown in Figure 1 to Figure 4, (2) rubber big gun is made up of junked tire or waste and old conveyer belt by net, press against overlap joint and leave certain space, its surrounding is each fixes a usual rubber strip, corner and center bolt (4) are fixed, and all the other ground square punch are fixing with (5) traverse. Rubber big gun is netted both sides (1) wire gauze, and three realizes firm connection, and is worn (6) overlap joint hole by surrounding symmetry or (7) overlap joint hook facilitates this Novel explosion flyrock protection device to realize batch to splice use at big gun. Namely outermost layer water covering passes through the fixing nut of (10) water bag, the fixing bolt of (11) water bag and the fixing tabletting of (9) water bag and realizes fixing (3) water bag, can compress or loosen the fixing tabletting of (9) water bag thus realizing the fixing of (3) water bag and dismounting by tightening or loosening the fixing nut of top (10) water bag. Surrounding at this Novel explosion flyrock protection device avoids (6) overlap joint hole or (7) overlap joint hook is fixed nut by the fixing bolt of (12) handle and (13) handle (8) handle is fixed on the surrounding of device.

In Practical Project operates, using this Novel explosion flyrock protection device as assembly, hole can be overlapped by (6) or (7) overlap joint hook realizes the splicing of various area specification thus being applicable to different engineering instructions for uses.

This utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment is any conspicuously improved or change that those skilled in the art are made, all without the protection domain beyond design of the present utility model and claims.
