Abstract
An anti-scour air door is characterized by comprising a door plate (1), a low-resilience sponge layer (2), a rubber handle (3), a canvas (4) and a door frame (5), wherein two faces of the door plate (1) are covered by the low-resilience sponge layer (2) which is covered by the canvas (4), and the door frame (5) is embedded in walls. The door plate is made from the material of good plasticity and sock-adsorption buffer function. Two surfaces of the door plates are covered by the low-resilience sponge layer of 100mm thickness, to effectively prevent users to impact the air door after being impacted, thereby preventing shock movement. The anti-scour air door can effectively protect head and body in the impact to the air door, when the workers are in the danger area of rock burst and the rock burst occurs, thereby reducing hurt ratio of workers and realizing safe production.
Description
Technical field
The utility model relates to a kind of erosion control air door in the deathtrap that the bump influence is arranged in the mining industry.
Background technology
Coal mine rock burst is that the down-hole country rock destroys suddenly, cause strenuous vibration, and, be the power natural calamity that Safety of Coal Mine Production in another kind of serious threat after gas, water, fire, top board, coal dust five the Nature disasters with a kind of ore deposit pressure release phenomenon that a large amount of coals (rock), gas are gushed out suddenly.Put down in writing bump the earliest and occur in Britain Nanshi tower good fortune colliery in 1738, comprise more than 20 countries and regions such as China, Russia, South Africa, Poland, the U.S., Germany, Japan now all in the threat that is subjected to bump in varying degrees, coal companies such as Beijing of China, Datong District, Fushun, Beipiao City, Yanzhou, Zaozhuang, Xuzhou, Yima all exist the harm of bump.Mining depth reaches all in various degree the threats that is subjected to bump of the above most of mines of 500M, and in the bump generating process, underground operators is subjected to shock wave and coal (rock) bump that jolts and is subjected to personal injury in limited space.
The colliery is made a leapleap forward along with the progressively increasing of mining depth by Yima coal industry group company, the geological structure complexity, and the bump disaster is serious.Once at 2-5 exploiting fields-400 level 25080 work planes serious bump disaster taking place, causes down surplus the lane 300 a meter tunnel all to destroy, all stifled real from a large amount of coal cinders that base plate is gushed out whole tunnel.The 23130 times lane driving steamed bread of corn in 2-3 exploiting fields (-400 level) are in 27 mouthfuls of generations in 07 year December bump disaster, and the shock wave that is produced causes air door to damage, and strikes personnel's head of opening air door, causes the personnel death.This mainly is that the vibration frequency of human organ is consistent with the vibration frequency of bump, produces that resonance causes.And the oscillatory acceleration (shock wave) that bump produces makes the people strike object (or object strikes is behind personnel), causes that the resonance personnel's is injured.Expert's 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
2Along with adopting dark increasing, frequency and intensity that bump takes place all have the trend that increases the weight of.
Mainly concentrate on three aspects on the domestic direction that is positioned bump research: the one, the mechanism research that bump takes place; The 2nd, bump hazard assessment, the technical research that detects and forecast; The 3rd, the research of bump control measures.And do not have too much consideration at existing miner's articles for labour protection and protective gear.Existing air door is used plank more, and the outside tin plate parcel that adopts is made, when impact force is destroyed air door or the people is flushed to after causing the operating personnel to be clashed on the air door door-plate easily injured.Use the iron air door of mechanical chain and have in the colliery now, this has more increased personnel and has struck injured probability behind the air door.
Summary of the invention
The purpose of this utility model be exactly be to overcome above-mentioned deficiency of the prior art and provide a kind of in the mining industry has the deathtrap that bump produces the substitute of old-fashioned air door, press danger to cause casualties and injured degree with minimizing with being hit.
For achieving the above object, the utility model is to adopt following scheme to be achieved in that a kind of erosion control air door, by door-plate 1. it be, the slow-recovery sponge layer 2., rubber handle 3., canvas is 4., 5. doorframe is formed, wherein 2. 1. door-plate wrap up the slow-recovery sponge layer in the two sides, and 4. slow-recovery sponge layer 2. external application canvas wraps up, and 5. doorframe is embedded in the body of wall.3. rubber handle adopts soft material to be installed in the edge of open side, makes personnel can only could open air door in the side, and it is injured to have avoided air door to be subjected to bringing the personnel front after the impact force, and 1. door-plate adopts has good plasticity and shock-absorbing cushioning effect material is made.
The utility model air door: door handle adopts soft material to be installed in the edge of open side, makes personnel can only could open air door in the side, and it is injured to have avoided air door to be subjected to bringing the personnel front after the impact force.
The employing of the utility model air door door-plate has good plasticity and shock-absorbing cushioning effect material is made.The slow-recovery sponge parcel of 100MM is adopted on the door-plate two sides, and effectively protected personnel strikes the impact endurance test shock that causes behind the air door after being impacted.The use of the utility model erosion control air door can make the operating personnel who presses in the deathtrap in being subjected to the bump generating process with being hit; head has effectively obtained protection with health when taking place to impact with air door; thereby reduce the probability of injury to personnel, reach the purpose of safety in production.
Description of drawings

Fig. 2 is the utility model erosion control air door sectional drawing
The specific embodiment
Be the utility model air door shown in Fig. 1,3. rubber handle adopts soft material to be installed in the edge of open side, makes personnel can only could open air door in the side, and it is injured to have avoided air door to be subjected to bringing the personnel front after the impact force.
Be that 5. this air door doorframe is embedded in the body of wall shown in Fig. 2,1. door-plate adopts has good plasticity and shock-absorbing cushioning effect material is made, two sides parcel slow-recovery sponge layer 2., 4. slow-recovery sponge layer 2. external application canvas wraps up.
The utility model is reasonable in design, be installed in the bump deathtrap, down-hole, the damage of bump air door strikes the people or the people is subjected to striking on the air door after shock wave impacts as taking place, and can play the effect of shock-absorbing buffering effectively, reduce the injury to personnel probability, realize safety in production.
