Abstract
The utility model discloses an impact preventing helmet which is worn by an operating personnel in areas with the risks of impact pressure burst in a mining industry. The helmet is composed of a buffering washer which is arranged inside a high-strength helmet body, wherein the lower part of the helmet body is provided with a wide cap band with adjustable length. The impact preventing helmet has the advantage of reasonable design. A head part of the operating personnel can be free from striking so as to obtain protection in the process of the occurrence of the impact pressure burst, when the impact preventing helmet is worn by the operating personnel in areas with the risks of impact pressure burst under mining wells. Thus, physical injuries which are brought because of the impact pressure burst are reduced to a great extent and the purpose of safety production is achieved.
Description
One, technical field
The utility model relates to a kind of industry of digging up mine at the protecting against shock helmet that has the regional deathtrap operating personnel of impact to wear.
Two, background technology
Coal mine rock burst is that the down-hole country rock destroys suddenly, causes strenuous vibration and presses to manifest with a kind of ore deposit that a large amount of coal (rock) pieces are dished out, and be a kind of dynamic disaster of serious threat Safety of Coal Mine Production.Ji Zai bump occurs in Nanshi's tower good fortune colliery of Britain in 1738 the earliest.Now, in more than 20 countries and regions such as China, South Africa, Russia, Poland, the U.S., Germany, Japan all in the threat of pressing in varying degrees with being hit.All there is the bump disaster in mineral bureaus such as Beijing of China, Datong District, Fushun, Beipiao City, Yan Zhou, Zaozhuang, Xuzhou.Mining depth reaches the threat that the above most of mines of 500m are subjected to bump to some extent.In the bump generating process, operating personnel's bump that is hit and jolts in limited space can be subjected to personal injury.
Fushun Mining Group company tiger platform ore deposit, mining depth is big, and the coal seam is thick, complex structure, the bump disaster is serious, when the shallow coal seam more than the exploitation-255m level (apart from face of land 300m), overbump ground just once took place press.Along with the increase of mining depth, bump manifests more and more frequent.Impact strength and destructiveness are increasing, particularly mining depth reach apart from face of land 500m take place when above particularly frequent and strong.With adopting dark increasing, bump all has the trend that increases the weight of in frequency, intensity and harm.
Bump can cause large tracts of land roof fall, pucking, the tunnel roof and floor of working face to close up, if having the people to work in generation area, then may produce injury to it, even cause death.Studies show that, bump takes place after, the main position of injury to personnel is a brain, account for more than 90%, secondly be the mechanical failure of chest, comprise that rib fractures etc. to account for 60%.And internal's damage mainly to be lung, the heart, stomach etc. account for 19%, secondly also account for 19% again for fractureing of upper and lower extremities.This mainly is that the vibration frequency of each organ of human body is consistent with the vibration frequency of bump, produces that resonance causes.And the oscillatory acceleration that bump produces makes human impact's object, causes resonance personnel's injures and deaths.Result of study shows, the energy that discharges in vibrations is greater than 10
5Under the situation of J (1.7 grades of Richter scales), the vibration amplitude of oscillatory acceleration may from 2 to 100, even greater than 1000m/S
2
Domestic being on the bump research direction mainly concentrates on three aspects: the one, and the research of bump genesis mechanism; The 2nd, bump hazard assessment, detection and forecasting technique research; The 3rd, the research of bump control measures.Yet because the bump genesis mechanism is very complicated, the bump problem is still a difficult problem that does not thoroughly solve as yet at present both at home and abroad, presses still on a lot of mine damaging impact ground and often takes place.Simultaneously, in existing miner's articles for labour protection, there is not to consider to weigh wounded harmful security protection equipment with being hit.When original mining Capsule was worn, the gap was less between helmet body and the human body head, does not have padded coaming, and when taking place to impact, impulsive force directly acts on human body head.And, the impact strength deficiency of Capsule, inefficacys of easily breaking when take place impacting tied up and restricted meticulously, easily flown by shake or comes off.
Three, summary of the invention
The purpose of this utility model provides a kind of protecting against shock helmet that has bump deathtrap operating personnel to wear in the mining industry, presses with minimizing with being hit and endangers casualties and the extent of injury that causes.
The utility model---the protecting against shock helmet is to establish buffer gasket to constitute in high strength helmet body, and length-adjustable wide in width band is arranged at helmet body bottom.
The utility model protecting against shock helmet is to adopt the shock proof ABS resin of light industrial chemicals to make.Folder is filled with the buffer gasket that thicker padded coaming is made between helmet body in the protecting against shock helmet and the human body head, the impact that human body head is subjected to when having slowed down collision, protecting against shock helmet impact strength is increased, can protect the impact of outer bound pair human body head effectively, and but the wide in width band of length regulated at will arranged on the protecting against shock helmet, comfortable wearing, easy to operate, difficult drop-off.Therefore, use of the present utility model can make the operating personnel in the bump generating process, and head is avoided bump and is protected, and reaches the purpose of safety in production.
Four, description of drawings
Fig. 1 is the internal structure schematic diagram of the protecting against shock helmet of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Five, the specific embodiment
Shown in Fig. 1 to Fig. 2 is the utility model---the protecting against shock helmet.The buffer gasket of establishing in the helmet body 5 of the protecting against shock helmet is coupled together by guipure 2 by buffering hatband 3 and crown protection pad 1, and is fixed in the helmet body 5 with bolt 6.The mine lamp deck and the air-vent that have fixing mine lamp to use on the helmet body.The wide in width band 4 of the protecting against shock helmet is provided with the buckle 7 of regulating length; 9 is the lower jaw pad on the hatband, and 8 is the hatband clamp.
The utility model is reasonable in design, and the protecting against shock helmet adopts the ABS resin of the light anti-HI high impact of industrial chemicals to make.Before entering the deathtrap, the operating personnel who enters bump deathtrap, down-hole correctly worn the utility model protecting against shock helmet on request; as bump takes place in operation process; when the operation personnel head bump that is hit and jolts; under the protection of the utility model protecting against shock helmet; can alleviate injury, realize safety in production operating personnel's human body.
