Description

Ramp-down device is used in a kind of novel high-rise life saving and transport
Technical field
The utility model relates to a kind of safety rescue transport devices, and in particular to a kind of novel high-rise life saving and transport are with slow Falling unit.
Background technique
With the quickening of urbanization process, skyscraper increases rapidly, however, when occur fire, earthquake, the attack of terrorism, When the emergency events such as gas leak, normal fire escape cannot be used, and cause personnel that cannot flee from skyscraper in time, easily be gone out The major accident of the existing dead group's wound of group, therefore we must design a kind of device for high building emergency escape.
A variety of ramp-down devices for high-rise life saving are had existed in the market, and cardinal principle includes following several, clip Escape device for high-rise buildings: the device mainly generate system control power by lever, the double force-increasing mechanism fork-like farm tools used in ancient China of connecting rod control in Contraband shape slot it is dynamic, Determine friction block to clamp rope and it is allowed at the uniform velocity to glide, major advantage is to automatically control decrease speed, but user cannot Velocity magnitude is voluntarily controlled, speed cannot be kept to zero in time when easily causing fear, and landing.Brucker survival capsule drops in rope: its principle is Rope is vertical to wear a kind of slow lowering means, and is fixed with protective case, plays falling bodies decelerating effect using tribology principle.The device Great advantage be that can reuse up and down, but without enough safety precautions, safety coefficient is not high.Tiltedly rope is slided Drop: being fastened with one, long rope is having dangerous situation upstairs, and the other end of rope is fastened on the stress point of lower section one or hauled with automobile Form a ramp rate escape;Escape to air cushion packet pad: with air cushion packet pad, distress personnel is jumped out of the building escape, they main excellent Point is that decrease speed is fast, can more people utilize, but risk is big, and is not suitable for the disadvantaged group such as old man, children.Apparatus above is not It is popularized, to find out its cause, the problem of being primarily present following several respects, safety issue: most counting apparatus does not have protective device, Especially when close to ground, without buffer unit, and reliability is insufficient, such as tiltedly rope downhill race;Practicability problem: most counting apparatus There is a problem of what speed was difficult to control, need the completely manual control of distress personnel, and other people is needed to assist, as brucker survival capsule drops in rope. If survivor was not used, and declined from eminence, it is not easy to hold the speed of decline;Applicability problem: as air cushion packet pad this Class device does not consider its use in disadvantaged group, such as child, old man, disabled person or patient.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, a kind of novel high-rise life saving and fortune are provided Defeated to use ramp-down device, the installation weight is light, easy to use, assists without power mechanism with other people, automatic speed-limiting can ensure to meet Safety when stationarity and landing when dangerous personnel are landed, while can play high building translocation;The device is widely applicable, energy It is used widely in disadvantaged group, and lifesaving inefficiency can be improved.
To achieve the above object, the utility model is using following technical scheme: it includes wirerope 6, snak link 4, it It include also shell 1, bi-face sealed ball bearing 2, centrifugal braking mechanism 3, rope woolding axis 5, the shell 1 is by left apparatus body 11 and the right side Apparatus body 12 is connected by screw to composition, and two bi-face sealed ball bearings 2 are separately positioned on left apparatus body 11 and right apparatus body 12 Middle part, rope woolding axis 5 is fixed on shell 1 by bi-face sealed ball bearing 2, and two centrifugal braking mechanisms 3 are separately mounted to twine 5 left and right ends of reel for rope, wirerope 6 are wrapped on rope woolding axis 5, and one end and the rope woolding axis 5 of wirerope 6 connect firmly, wirerope 6 it is another End connection snak link 4.
The rope woolding axis 5 includes central spindle 51 and flat key 52, and two flat keys 52 are separately positioned on 51 left and right sides of central spindle.
The centrifugal braking mechanism 3 includes drive block 31, friction block group 32, guiding steel disc 33, drag ring 34, drive block 31 are arranged in the square groove inside shell 1 and are connect by flat key 52 with rope woolding axis 5, connect firmly disc on the end face of drive block 31 Guiding steel disc 33,31 periphery of drive block is equipped with friction block group 32, annular groove is provided in friction block group 32, and guiding steel disc 33 is inlayed In the annular groove in friction block group 32, two drag rings 34 are embedded in left apparatus body 11 and right apparatus body 12 and tight respectively Frictionally block group 32.
The friction block group 32 includes friction block 321 and extension spring 322, one group of 321 two pieces of friction block, two pieces friction Circular configuration is formed by the connection of extension spring 322 between block 321.
End cap 13 is respectively arranged with outside 1 two sides of shell.
1 lower part of shell is provided with load-bearing axle 14, and one end of load-bearing axle 14 is provided with hanging ring 141.
Four square holes 111 being evenly distributed are provided on 11 medial plane of left apparatus body.Square hole 111 is used for It is coupled backpack strip, lands after facilitating personnel's harness from eminence.
Working principle of the utility model is: personnel can be by being connected to four sides in left 11 plane of apparatus body for backpack strip It is born after in shape hole 111 in back, weight can be hung in part load-bearing axle 14, and the snak link 4 of connecting steel wire ropes 6, which is hung over, to be built It builds on the reliable connector of object, personnel or weight can be realized from eminence safe falling, wirerope 6 is constantly from rope woolding axis when landing It is issued on 5, drives rope woolding axis 5 to rotate when sending, rotation rope woolding axis 5 makes the drive block 31 being connected on rope woolding axis 5 also together Rotation, so that the friction block group 32 of 31 outside of drive block be driven to rotate synchronously, friction block group 32 is because there is guiding steel disc 33 to be directed at It will not be axially moveable when rotating, and thrown away when friction block group 32 rotates by the effect of centripetal force outward, press to friction Ring 34 generates frictional force, this frictional force will hinder the rotation of rope woolding axis 5, i.e. 5 revolving speed of rope woolding axis is slack-off, and so on realizes fortune Dynamic balance, personnel or weight are with slower speed (average 2m/s or so) decline.When closer from the ground on rope woolding axis 5 around steel Cord 6 is fewer, i.e., its diameter is also smaller, and the circle number that part rope woolding axis 5 rotates when declining same height is more, the centripetal force of generation It is bigger, so that sinking speed is also slower, realize safe landing.
After adopting the above technical scheme, the utility model has the beneficial effect that the present apparatus is using the gravity of human body or weight Power drives rope woolding axis to rotate, so that friction block be driven to rotate, under centripetal force effect, friction block presses to drag ring and generates friction Power.People or weight decline it is faster, rope woolding axis rotation it is faster, friction block generate centripetal force it is bigger, hinder rope woolding axis rotation rub Wipe power it is also bigger, frictional force is bigger, rope woolding axis rotation it is slower, be finally reached a balance, enable personnel or weight decline and The speed of decline is lower (close to uniform motion), it is ensured that the average speed of 2 m/s of human body or so declines, and makes personnel or again Object lands safely.
