Abstract
The present invention is the recoverable high-rise descent control device with adaptation function, including transmission mechanism, arrestment mechanism, rope machine for automatically recovering structure.Spool turns are pulled by rope, reel drives planetary gear to rotate, and the rotation of the sun gear engaged and mandrel is driven by planetary gear.Now brake pad produces frictional resistance with cabinet wall, realizes retarding braking, survivor is landed with safe speed.When survivor is two people, because the effect of centrifugal force causes the spring of connection brake pad internal screw to fasten, brake pad produces resistance with box house friction, obtains the safe speed that two people escape declines.After survivor lands, unloaded rope counter motion in the case where the coil of strip spring of rope recovering mechanism drives, final uniform winding is ready on reel for next use.Advantage of the invention is that rope can automatically reclaim, can automatically adjust decrease speed, small volume, stable performance according to survivor's number difference.
Description
Technical field
The invention belongs to high-rise life saving technical field, more particularly to a kind of adaptive fall-slowing device for rescuing from high building of recoverable.
Background technology
With the development in epoch and the continuous propulsion of Process of Urbanization Construction, not only the high building such as commercial center, high and new tech park stands in great numbers, and common residential quarter residential building also begins to gradually tend to high stratification.But due to skyscraper possessed potential safety hazard in itself, once the accidental pollution events such as fire, earthquake occur, great casualties and property loss are easily caused, therefore, the safe escape of skyscraper turns into the social concern that people pay close attention to further.
At present, the more popular small-sized escape device for high-rise buildings of domestic and international research field mainly has following 3 type：Mechanical friction damp type escape device, electromagnetic damping formula escape device, Hydrautic damping escape device.Wherein, required precision of the Hydrautic damping escape device to equipment is very high, and hydraulic oil and hydraulic system potted component are very high to the susceptibility of temperature, easily protected from environmental, it is difficult to ensure that device normal work under high temperature of fire state, and using it is cumbersome it is time-consuming, cost is high.Electromagnetic damping formula escape device, its reliability is poor, the winding and electric elements used once occur insulation sex chromosome mosaicism potential safety hazard will be brought to survivor, job stability it is difficult to ensure that.Fall-slowing device for rescuing from high building majority on the market is to belong to mechanical friction damp type this is a kind of, frictional resistance torque is produced under the action of the centrifugal force, and the speed of decline is limited in a safe range, does not account for the body weight question of people, cause decrease speed too fast or excessively slow, it is impossible to adaptive；And the recovery structure of steel wire cable is mostly using reciprocating, i.e. people ties up to one end decline of rope, the other end of rope rises therewith, then the next man is just declined using the other end gone up, and so on circulate, such reciprocating recovery structure needs an external reel, uses very inconvenient；Minority excessive velocities when withdrawing rope using the descending lifeline of automatic recovery rope structure, easily damage the window of periphery resident family and external article.
The content of the invention

Embodiment
Further details of elaboration is done to the present invention with reference to the accompanying drawings and detailed description.
As Figure 1-Figure 2, the present invention is a kind of adaptive fall-slowing device for rescuing from high building of recoverable, including transmission mechanism, arrestment mechanism, rope machine for automatically recovering structure.
The transmission mechanism, it is fixed on including mandrel 2 by screw on casing 11, internal gear 4 is fixedly connected with the screw of casing 11, sun gear 10 is connected with mandrel 2 by being interference fitted, line wheel 3 is to be fixed as one with planet wheel spindle, three planetary gears 5 are installed on planet wheel spindle, planetary gear 5 with internal gear 4 to internal messing, and with sun gear 10 to external toothing；Line wheel 3 is pulled to rotate when steel wire rope declines, line wheel 3 drives planetary gear 5 to rotate, and planetary gear 5 drives the sun gear 10 with its external toothing to rotate, to realize speedup.
The arrestment mechanism, connected including center of friction block 9 and sun gear 10 by being interference fitted, sun gear multi-diameter shaft limits the axial movement of center of friction block 9, brake pad 8 is enclosed on four axles of the surrounding of center of friction block 9 stretching, and it is fixed on by screw on center of friction block 9, head of screw is cased with spring 7 with leaving a fixed gap outside brake pad in the gap；When steel wire rope declines, the speedup of sun gear 10 is realized by transmission mechanism, drives center of friction block 9 to rotate, under the influence of centrifugal force, brake pad 8 tightly pushes down the inwall of box plate 11 and produces frictional resistance torque, realizes retarding braking target；Different according to centrifugal force caused by the difference of people's body weight, the active force of spring 8 is also different, can adjust the size of moment of friction, adaptively to adjust decrease speed of the survivor in the range of safe speed；And due to the presence of spring 8, when steel wire rope reclaims, centrifugal force caused by scroll spring resilience is smaller, overcome the moment of friction after the active force of spring 8 smaller, friction mechanism does not almost work, when rope recovery is too fast, centrifugal force is more than the active force of spring, produces the recovery speed of moment of friction control rope.
The rope machine for automatically recovering structure, including line wheel 3 are connected in mandrel 2 by gap, and the one end of scroll spring 1 is fixed in mandrel 2 by screw, and the other end is fixed in line wheel 3；Pulls wire wheel rotates when steel wire rope declines, and scroll spring 1 compresses, and when reclaiming steel wire rope, scroll spring resilience, drives line wheel to rotate backward, and steel wire rope one encloses circle and is wound into lines until all recovery.
