Abstract
The utility model discloses a shockproof mine earthquake stool. The shockproof mine earthquake stool comprises an upper supporting plate and a lower supporting plate, a cylinder is arranged on the lower supporting plate, a cylinder sleeve sleeved on the cylinder is arranged on the upper supporting plate, a spring supported between the upper and lower supporting plates is arranged in the cylinder, and supporting legs are arranged below the lower supporting plate. The upper supporting plate is a riding part, the lower supporting plate is a base part in contact with a bottom plate, and the middle part is changed into the energy absorbing spring and the telescopic cylinder sleeve; the functions of eliminating shock energy by the energy absorbing spring and greatly reducing the amplitude of the supporting plate of the riding part during shock mine earthquake are realized through energy absorbing buffer, so that effects of weakening the shock strength and effectively protecting a human body are achieved. The shockproof mine earthquake stool is simple in structure, convenient to use and good in effect.
Description
Technical field
The utility model relates to a kind of stool, and especially a kind of industry that is applicable to dig up mine is having the protecting against shock ore deposit shake stool that ore deposit shakes, bump deathtrap operating personnel has a rest use temporarily.
Background technology
Ore deposit shake and impulsion pressure are the major natural disasters that affect China's mining.The ore deposit shake is the seismic activity that mining causes, is elastic wave and propagation athletic performance thereof that the disrumpent feelings motion of coal and rock produces, is the special shape of strata behaviors, and the mine vibrations will cause rock mass release and impulsion pressure disaster.Ore deposit shake is the phenomenon of difficult grasp in world's deep layer mining,, in the situation that the ore deposit shake is strong, can feels on ground and the vibrations of rock mass the building on ground be destroyed.
Ore deposit shake occurs in mainly that geological structure more complicated, crustal stress (tectonic stress) are large, the more significant mining area of fault activities., in China, occur that ore deposit shakes and there are the mining areas such as Beijing, Xin Wen, Fushun, Beipiao City, Datong District, Huating, Hegang, Qitaihe, Fuxin, Xuzhou, Yan Kuang, Yima in the mining area that forms disaster.Along with the continuous increase of mining depth, ore deposit shake frequency and energy all significantly increase, and the shake of maximum ore deposit can reach 4～6 grades, and even the ground seismaesthesia is strong, more than coverage can reach 10km.
Impulsion pressure is one of coal rock dynamic disaster phenomenon of serious threat mine safety production, and Germany, South Africa, the former Soviet Union, the U.S., Poland, Japan and China etc. main mining country in the world the overbump ore deposit all occurs press.Have nearly 100 pairs of big-and-middle-sized mine generation overbump ore deposits to press in China, and along with the continuous increase of the pit mining degree of depth, the danger of impulsion pressure and harm also are on the rise, the mechanism of impulsion pressure is extremely complicated, and influence factor is numerous.
The shake of strong ore deposit and impulsion pressure be coal petrography with suddenly, sharply, fierce form discharges elastic energy, produces sharp pounding, causes the destruction of roadway and a kind of phenomenon of human casualty accident.Its distinguishing feature is: (1) is sudden.Generally there is no obvious macroscopic premonitory, occur suddenly often, be difficult to time, place and intensity that prior Accurate Prediction occurs.(2) instantaneous vibratility.Generating process is sharply and of short duration, and the lasting vibrations time is no more than tens seconds usually, and with the huge sound and strong vibrations, vibrations can involve even tens kms of several kms as blast, and even there is the earthquake sensation on ground.(3) considerable damage.Cause top board moment obviously to sink, base plate cracking is suddenly heaved and is even connect top, and coal body is broken suddenly also dishes out from rib, stops up tunnel, destroys support; See that from consequence bump usually causes heavy casualties and huge production loss.
Ore deposit shake and impulsion pressure mainly contain dual mode to the injury of the person, the one, coal body is gone out directly the people to be pushed over bury and is caused death, the 2nd, sharp pounding is stood by personnel or the base plate sat is delivered to human body, cause the human organ injury, comprise head and chest impact, the shake of visceral rupture, backbone is disconnected etc., serious puts people's death.
Because ore deposit shake is in close relations with exploitation, as long as there is mining activity will inevitably follow the ore deposit shake, and impulsion pressure to be ore deposit shake and ore deposit press a kind of extreme form that manifests.Yet, due to ore deposit shake and the bump genesis mechanism very complicated, be still at present a difficult problem that not yet thoroughly solves both at home and abroad.in China's mine, miner's working time is all long at present, as " three or eight system " working system commonly used, the workman can reach about 10 hours working time of once going into the well, labour intensity is very large, need to take a load off one's feet unavoidably during this time, when the workman adopts common stool with seated resting, the body trunk part will directly contact with base plate by being rigidly connected, but because the ore deposit shake has sudden, in case the ore deposit shake occurs to impact, just lost the leg curvature buffer protection ability that has while originally adopting stance, will certainly be to human body especially trunk through the strong ore deposit shake of overdamping, the vitals such as internal organ and backbone damage.For this present situation, a kind of sudden impact ore deposit of can resisting of active demand shakes, avoids or reduces the rest device that the person is caused great bodily injury, the utility model---the invention of protecting against shock ore deposit shake stool, can allow workman's interim rest when ore deposit shake, the operation of impulsion pressure zone use, can effectively avoid and reduce the harm that disaster is brought.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in prior art, and a kind of protecting against shock ore deposit simple in structure, easy to use shake stool is provided.
For achieving the above object, protecting against shock of the present utility model ore deposit shake stool, comprise upper bearing plate and lower support plate, lower support plate is provided with cylindrical drum, upper bearing plate is provided with the cylindrical sleeves that is sleeved on cylindrical drum, be provided with the spring that is supported between lower support plate in cylindrical drum, described lower support plate is provided with supporting leg.
Be provided with the steel wire rope that flexibly connects between described both ends of the spring; Described supporting leg is 3 or 4; Described supporting leg bottom is provided with rubber blanket.
Beneficial effect: the utility model increases energy-absorbing buffer device between two-layer support plate, by built-in spring and flexibly connect steel wire rope and fasten telescopic cylindrical sleeves and form, in the mining industry, temporarily the have a rest protecting against shock ore deposit shake stool of use of the staff of ore deposit shake, the operation of bump deathtrap is arranged, the security of raising work and operating efficiency, reduce the personal injury degree that impact endurance test shock causes.This two-layer support plate in stool up and down all adopts the ABS resin material light, that intensity is high and shock resistance is good to make; upper strata is for taking part; lower floor is the base portion that contacts with base plate; mid portion changes into by energy-absorbing spring, scalable cylindrical sleeves, flexibly connects the energy-absorbing buffer device that steel wire rope forms; while having realized that the shake of impact ore deposit occurs; vibration energy subdues, takes by the energy-absorbing spring function that the partial support band amplitude greatly reduces, thereby plays the effect that weakens shockproofness and human body is played effective protection.It is simple in structure, easy to use, effective.
