Description
Affiliated technical field
The utility model relates to a kind ofly can control decrease speed, from the device of eminence safe falling, the people who is particularly useful for being in eminence (high building or high tower etc.) is because of building () ladder or the passage emergency escape after being blocked by pyrotechnics.
Background technology
At present, when urgent dangerous situation takes place, as fire, known method from high-building safe escaping is normally got off along building () ladder or passageway for fire apparatus, if but building () ladder or passage just are difficult to leave safely eminence by the big fire blockade.Also there is the people to slide once in a while along rope, but this needs sufficiently long rope, survivor's fitness is relatively good, if to such an extent as to the too high rope in the residing position of survivor falls short of or wrist and arm do not have enough strength carrying body wts to slide just to be difficult to safety to leave eminence.Most cases can only wait for rescue, but the rescue personnel is on the scene and needs certain hour, and the survivor must have the ability to adhere to a period of time, can bear the poison gas that paint waits organic compound combustion to produce, and building can not collapse.But common people breathed 10 minutes in the poison gas that organic compound combustions such as paint produce in the actual fire, and the hope of existence is just little; The house reinforced concrete structure is heated and is comminuted destruction and causes easily collapsing, as September 11 attacks; Along with the development in city, present high building is more and more higher, the eminence that 13 floors are above, and aerial ladder and giant all can not reach height like this.Therefore, survivor's self-help escape is just extremely important!
In the reality, September 11 attacks, the fire prevention equipment of the U.S. is not talkative not advanced, but can only see helplessly that the building burns down.
Not long ago, Shanghai collegian's dormitory caused because of " immersion heater " that the room was on fire, and 4 schoolgirls jump off from the 6th buildings, and none survived.
Summary of the invention
For the people that helps to be in eminence (high building or high tower) because of building () ladder or the passage emergency escape after being blocked by pyrotechnics, the utility model provides a kind of can control decrease speed, from the device of eminence safe falling, prevents from that human body from landing to damage.
The technical scheme that its technical problem that solves the utility model adopts is: at the top of metal shell one aperture is arranged, has steel cable to pass aperture and be fixed in the axis in the shell and be wound in axis, steel wire rope be positioned at the outer end of shell fixedly connected hook; Axis is fixed with rotating disk/or fluted disc; Rotating disk outer is with the supporting conicalplate-coil spring of steel plate/or leaf spring/or supporting wire spring of steel plate, also has brake bar/or brake(-holder) block/or slide bar; The shell lateral surface has handle, and the shell outer bottom has damping spring, and damping spring connects back of the body pocket; Handgrip is arranged at shell lateral surface or bottom.
Such scheme can be divided into three parts: deceleration part, brake portion, other parts.Rotating disk and leaf spring/or supporting wire spring of steel plate/or the supporting conicalplate-coil spring of steel plate belong to deceleration part, brake bar/or brake(-holder) block/or slide bar belong to brake portion, all the other belong to other parts.
Each parts and overall structure relation is described in detail in detail below: at the device top one hook is arranged, link up with fixedly connected main rope, the aperture that the main rope other end passes crust of the device top is fixed on the aperture of the axis in the shell and is wound in axis.
Axis is fixed with rotating disk by unidirectional brightness formula, and (be to be that single load bearing rotates between axis and the rotating disk, axis drive rotating disk rotates together in the drive axis rotating process when main rope is outwards pulled out; But can not drive rotating disk and rotate together when the axis counter-rotation involves in main rope in the shell and is wrapped in the axis process axis).One folding crank handle is arranged at shell lateral surface axis position, folding crank handle is that the buckle-type sleeve is connected with axis, buckle is connected with axis when pulling open folding crank handle, thereby turning handle can drive axis and rotate and to involve in main rope in the shell and be wrapped in axis and rotating disk does not rotate, buckle is thrown off with axis when closing folding crank handle, and axis just drove rotating disk and rotates together but can not drive folding crank handle rotation when steel wire rope was pulled out and driven axis and rotate.The circumference that is fixed with tooth or rotating disk in the side that does not contact steel wire rope of rotating disk is made dentation and is formed fluted disc.
Rotating disk outer is with the supporting conicalplate-coil spring of steel plate/or leaf spring/or supporting wire spring of steel plate.One end of the steel plate of a supporting conicalplate-coil spring/or end of the steel plate of leaf spring/or an end of the steel plate of supporting wire spring insert two between cog of rotating disk or fluted disc; The other end of the steel plate of supporting conicalplate-coil spring is fixed in paraxonic, the other end of the steel plate of leaf spring is fixed in housing, the other end of the steel plate of supporting wire spring is positioned at the top of wire spring and has pulley to connect, and the side mid portion of the steel plate of supporting wire spring has a fixed axis and the space of a whole page to prize around fixed axis.Paraxonic is positioned at the axis next door, the fixedly connected paraxonic of conicalplate-coil spring one end, and the conicalplate-coil spring other end is fixed in housing, the also fixedly connected paraxonic of an end of the steel plate of supporting conicalplate-coil spring.Wire spring is installed in the sleeve of two cup-shapeds and an end is hinged in housing, and two length sleeves all are shorter than the spring normal length, and one of them sleeve is inserted in another sleeve and is capable of expansion and contraction.
The periphery of rotating disk also has brake bar/or brake(-holder) block/or slide bar.The hollow part of brake bar one end insertion rotating disk or two between cog of fluted disc make it and can not rotate when static, the other end is positioned at the socket of housing and connects wire spring and little steel wire rope, and little steel wire penetrating wire spring connects the startup handle of shell lateral surface or bottom handgrip.Brake(-holder) block is positioned at the side or the top of round bar, periphery or the side of being close to rotating disk when static make it and can not rotate, round bar is positioned at the socket of housing and connects wire spring and little steel wire rope, and little steel wire penetrating wire spring connects the startup handle of shell lateral surface or bottom handgrip.The slide bar two ends are positioned at the chute of housing, and the tooth that slide bar blocks rotating disk when static makes it and can not rotate, and the mid point of slide bar connects wire spring and little steel wire rope, and little steel wire penetrating wire spring connects the startup handle of shell lateral surface or bottom handgrip.
The shell outer bottom has damping spring, and damping spring connects seat.
The a certain position that human body is in high building has the gravitional force with respect to ground, gravitional force is converted into the kinetic energy of rotating disk by the main rope that is wrapped in axis, when rotating disk is begun to rotate by first tooth, tooth to an end of the steel plate of supporting conicalplate-coil spring/or end of leaf spring/or an end of the steel plate of supporting wire spring produce pressure, because the effect of spring, one end of the steel plate of a supporting conicalplate-coil spring/or end of leaf spring/or an end of the steel plate of supporting wire spring also tooth is produced reaction force, slow down the velocity of rotation of rotating disk, thus the decrease speed of reducing human; When tooth forwards to and the steel plate of supporting conicalplate-coil spring/or the steel plate of leaf spring/or during the tangent position of the steel plate of supporting wire spring, conicalplate-coil spring/or leaf spring/or wire spring to be compressed distortion maximum, at this moment, the elastic potential energy maximum, after tooth turns over the point of contact, spring moment recovery deformation, externally acting, elastic potential energy changes into momentum, make supporting conicalplate-coil spring steel plate an end/or end of leaf spring/or an end of the steel plate of supporting wire spring second tooth produced resistance, stop second rotation that tooth causes because of the effect of body weight for humans power.The distance that this moment, human body descended equals the length of main rope on the pairing axis of distance of two between cog, and (distance of establishing two between cog is S, the tooth radius of rotating disk is n a times of axis radius, then the distance that this moment, human body descended is S/n, be that S is divided by n), the human body gravitional force of this distance except that sub-fraction because of friction consume remaining elastic potential energy that is converted into spring earlier the moment after first tooth turns over the point of contact changes into momentum to second tooth then, make second tooth slow down, second tooth repeats the motion of first tooth again, energy repeats above-mentioned conversion again, go round and begin again, periodic motion makes rotating disk slowly rotate with certain speed, and human body slowly descends with certain speed.
Instantly the reduction of speed degree feel too soon to fear very much or the decline process in run into the startup handle that unclamps handgrip when emergency need promptly stop and can suddenly stopping.Because after unclamping the startup handle of handgrip because the effect of spring, brake bar one end insert the hollow part of rotating disk or two between cog of fluted disc/or the periphery of brake(-holder) block friction rotating disk or side/or slide bar block the tooth of rotating disk, rotating disk can not rotate, human body stops to descend.
If also want to continue to descend, the startup handle that pinches handgrip just can continue to descend.Because after pinching the startup handle of handgrip, the little steel wire rope pulling brake bar that links to each other with the startup handle/or brake(-holder) block/or slide bar, brake bar one end withdraws from the hollow part of rotating disk or two between cog of fluted disc no longer block rotating disk, brake(-holder) block no longer withstands the periphery or the side of rotating disk, slide bar no longer blocks the tooth of rotating disk, rotating disk is free to rotate, and the main rope that is wrapped in axis can draw back, and human body can continue to descend.
The coefficient of elasticity and the body mass of spring adapt.Coefficient of elasticity too greatly then disk is stuck and can not rotates, and human body can not descend; Coefficient of elasticity is too little then can't offset the acceleration that the effect of body weight for humans power is caused, and the descender need frequently unclamp and pinch and start handle.According to the human body different quality, as 40kg, 50kg, 60kg, 70kg, 80kg etc., the steel wire rope of selecting the suitable spring of coefficient of elasticity and disposing suitable length manufactures the downfall equipment of different size model.
The beneficial effects of the utility model are: the people who is in high building can drop to ground safely when building () ladder or passage are blocked by big fire, also can be used for travelling and the physical training of gymnasium of park, and is convenient and practical.
