Description
Technical field
The utility model is related to machinery equipment field, and in particular to ramp-down device.
Background technology
As China's city size speed expands, the living environment of people turns to based on high-rise building substantially.And
The density of population is higher and higher, and especially in public places, a high-rise building disaster accident especially fire incident is likely to result in greatly
The casualties of amount.And rescue run measure extremely lags, almost at the bottleneck project for being difficult to crack.
Fire substantially not ad hoc on the skyscraper in China, rescuing device for earthquake at present, when fire, earthquake etc. can not
When drag occurs, elevator will be forbidden to use, and Fire lift can only provide fireman reluctantly or delivery fire-fighting equipment uses, largely
Personnel be only capable of going downstairs by escape stair walking, evacuation speed slowly and order be unable to control.In addition, the pregnant equal spies of the old,weak,sick and disabled
Different crowd is very inconvenient using escape stair, and tread event easily occurs, causes casualties.
Skyscraper on the market evacuates escape device at present, and it is soft to be broadly divided into descending lifeline (case), escaping rope, escape
Ladder, slow drop umbrella, slideway etc..Above-mentioned apparatus is mostly to be hung on the positions such as external wall or balcony outside open or semi-open form,
Interim use is opened when emergency occurs.The especially ramp-down device of turntable and rope structure, since its is simple in structure, operation
It is convenient, it has a wide range of applications.The ramp-down device of the structure is also extensively used for outdoor prompt drop activity, the necks such as outdoor rescue
Domain.
But the existing ramp-down device of the structure, wherein compressing member are generally pressing plate, the radial direction along turntable directly acts on
On rope, in order to have enough stiction between rope and turntable, the contact area of increase rope and turntable can be passed through
It realizes, compressing member then uses arc pressuring plate at this time, can also increase frictional force by increasing the pressure of compressing member.No matter logical
Which kind of above-mentioned mode is crossed to ensure the stiction between rope and turntable, is had the following problems always：1, in ramp-down device liter
During drop, there are force of sliding frictions between compressing member and rope, and the force of sliding friction and stiction pass in direct ratio
On the one hand the presence of system, the force of sliding friction will produce a large amount of heat, there are security risks, on the other hand rub for a long time,
Rope and compressing member can be made constantly to wear, equally exist security risk.2, compressing member is usually fixed, with usage time
Increase, compressing member is constantly worn, and pressure reduces, on the one hand stiction drops the heavy burden ability of ramp-down device also with reduction
Low, on the other hand there is also the risks that stiction is mutated into force of sliding friction.
Therefore, how existing ramp-down device is improved, so that it is overcome the problems, such as above-mentioned, be art technology
Personnel's problem urgently to be resolved hurrily.

Compared with prior art, the utility model has the following advantages：
1, the use of compressing member chain structure, and idler wheel is rotary, by the cunning between original compressing member and rope
Dynamic friction is transformed to rolling friction, remote in order to reach identical maximum static friction force, force of rolling friction between rope and turntable
Less than force of sliding friction, to realize that rope and compressing member wear smaller, the heat of generation is also less.
2, compressing member along turntable in circumferential direction about in turntable periphery, since the compressing member of chain structure can be freely curved
Song allows multiple idler wheels to suppress rope contact turntable simultaneously, on the one hand can generate the pressure of bigger, to increase rope and turn
On the other hand maximum static friction force between disk makes the frictional force between rope and compressing member be distributed to multiple points, reduce single
The load of idler wheel, and there is gap between idler wheel, it can preferably radiate, use is more safe and reliable.
3, due to compressing member be chain structure, can be freely bent, thus can by regulating part adjust idler wheel and
The distance between turntable adjusts the pressure of compressing member, adjusted to carry out maximum bear a heavy burden；In the long-term use, it compresses
Mechanism and rope have abrasion, can also be adjusted by regulating part, it is made to keep the loading weight of safety.
4, under external disk and idler wheel outer surface concave arc shape setting, be avoided that rope sideslip is even detached from, that improves mechanism can
By property；The inner disc corrugated setting in periphery makes its periphery have a Wave crest and wave trough, and multiple wave crests contact ropes, trough and rope it
Between have gap, make mechanism heat dissipation it is better；The setting of concave arc shape under idler wheel outer surface, moreover it is possible to increase the base of rope and idler wheel
Plinth area, identical in pressure, the pressure smaller that rope receives reduces the deformation of rope, also improves mechanism
Reliability.
5, the setting of arrestment mechanism, can decrease speed it is too fast when, carry out pushing braking, ensure that ramp-down device will not be under high speed
It falls, improves the safety of device；In addition prior effect is that operating personnel can be controlled by the arrestment mechanism moment to arrestment mechanism
The decrease speed of ramp-down device processed achievees the purpose that land safely.
6, leading the setting of lock station can make rope remain center, play the role of balance and stability；The setting side of handle
Convenient to operate personnel capture.
