Abstract
The utility model discloses a gear accelerating mechanism of a self-rescuer of high buildings, which comprises an acceleration gear set, a centrifugal wheel, a lever-type centrifugal block, and a centrifugal sleeve; the acceleration gear set is driven by a wire wheel enwound with cable wires, and a final gear of the acceleration gear set and a centrifugal wheel fixed on the shaft of the centrifugal wheel; the lever-type centrifugal block is fixed on the centrifugal wheel through a shaft pin; and the centrifugal sleeve which generates centrifugation acting force and counteracting force with the lever-type centrifugal block is fixed on the shell of the self-rescuer of high buildings. The mechanism can better control the falling speed of the portable self-rescuer of high buildings full-automatically so that the self-rescuer of high buildings is used more conveniently and safely.
Description
Technical field
The utility model relates to a kind of high-building self-help instrument, and is special relevant with the gear up mechanism of its control unwrapping wire.
Background technology
In the modern metropolitan cities, a lot of residents can live, work or amusement in high buildings and large mansions, because of certain reason just in case bump lifelong difficult fire of meeting ingeniously, there is not a kind of very capable instrument that can independent self-help escape, its consequence can not be imagined, and a lot of fire are arranged, and has all caused a large amount of casualties.
Existing on the market high-rise life saving mode has a lot, such as tiltedly rope downhill race escape, is to fasten with one in a long rope having dangerous situation upstairs, the other end of rope fasten below haul ramp rate of formation on stress point or with automobile; Such as drawing hanging basket to put with rope escape is fallen again; Allow the distress personnel escape of jumping out of the building also useful air cushion bag pad ... more than these escape modes all to be dependent on others, and in fire, convene personnel or etc. follow-up the coming of fire fighter could organize and implement.In addition, also have some to need the manually speed of the sliding rope device gliding speed of control of distress personnel oneself, some needs distress personnel to run quickly toward roof, because on roof, offered the security against fire road junction, arrived roof and equaled outdoor, dense smoke smoked less than, re-use special escape device for high-rise buildings, unsettled vertical downslide from the fire-fighting road junction, the people glides at a slow speed along rope.
In a word, high-building self-help instrument of the prior art uses all very inconvenient, and can't regulate decrease speed automatically in the escape process, and safety in utilization has much room for improvement.
The utility model content
The purpose of this utility model is to provide a kind of gear up mechanism of high-building self-help instrument, with the decrease speed of Automatic Control portable high-building self-help instrument better, makes high-building self-help instrument use more convenient, safety.
In order to reach above-mentioned purpose, solution of the present utility model is:
The gear up mechanism of high-building self-help instrument, form by speed increasing gear group, centrifugal wheel, centrifugal of lever, concentrator bowl, the speed increasing gear group is by the wire wheel transmission of lay winding wire ropes, the final stage gear of speed increasing gear group and centrifugal wheel are fixed on the centrifugal wheel shaft, centrifugal of lever is fixed on the centrifugal wheel by pivot pin, then is fixed on the housing of high-building self-help instrument with centrifugal concentrator bowl that produces centrifugal action power and reaction force of lever.
Have internal gear in the above-mentioned wire wheel, the internal gear of wire wheel is transmitted in the chopped-off head gear of speed increasing gear group.
After adopting said structure, the utility model is simple in structure, compact, can apply in the various high-building self-help instruments.When disaster comes, one end of steel wire rope is fixed, shouldering this high-building self-help instrument then jumps downwards, the escape personnel is in the decline process, rotate by steel wire rope pulling wire wheel by self gravitation, be transmitted in centrifugal wheel by the speed increasing gear group, drive centrifugal rotation at a high speed of lever, lever-type centrifugal is rotated the centrifugal force that produces radially at a high speed, centrifugal action produces the rotation that frictional force hinders centrifugal of lever at concentrator bowl, thereby hinders the centrifugal wheel rotation, hinder the payingoff speed of wire wheel again by the speed increasing gear group, thereby reach the purpose of automatic control escape personnel's decrease speed.The utility model is easy to use, and it is safer to land.
Description of drawings
Fig. 1 is the structural representation that the utility model applies to high-building self-help instrument;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Seeing also illustrated in figures 1 and 2ly, is preferred embodiment of the present utility model, has disclosed a kind of gear up mechanism of high-building self-help instrument, mainly is made up of speed increasing gear group 4, centrifugal wheel 5, centrifugal 6 of lever, concentrator bowl 9.
Each member annexation is among this embodiment: steel wire rope 10 is wrapped on the wire wheel 3, has internal gear 31 in the wire wheel 3, speed increasing gear group 4 is made up of three gears 41,42,43, the internal gear 31 of wire wheel 3 is transmitted in the chopped-off head gear 43 of speed increasing gear group 4, the final stage gear 41 of speed increasing gear group 4 and centrifugal wheel 5 are fixed on the centrifugal wheel shaft 8, are improved the rotating speed of centrifugal wheel 5 by speed increasing gear group 4.Centrifugal 6 of lever is fixed on the centrifugal wheel 5 by pivot pin 61 and (cooperates shown in Figure 2), is fixed on the housing 2 of high-building self-help instrument, referring to Fig. 1 with centrifugal 69 of concentrator bowl that produce centrifugal action power and reaction force of lever.
The utility model is simple in structure, compact, can apply in the various high-building self-help instruments.When disaster comes, one end of steel wire rope 10 is fixed, shouldering this high-building self-help instrument then jumps downwards, the escape personnel is in the decline process, rotate by steel wire rope 10 pulling wire wheels 3 by self gravitation, be transmitted in centrifugal wheel 5 by speed increasing gear group 4, drive centrifugal 6 rotation at a high speed of lever, lever-type centrifugal 6 is rotated the centrifugal force that produces radially at a high speed, centrifugal action produces the rotation that frictional force hinders centrifugal 6 of lever and centrifugal wheel 5 at concentrator bowl 9, hinders the payingoff speed of wire wheel 3 again by speed increasing gear group 4, high-building self-help instrument is descended with certain speed, thereby reach the purpose of automatic control escape personnel's decrease speed.
Claims (2)
1, the gear up mechanism of high-building self-help instrument, it is characterized in that: form by speed increasing gear group, centrifugal wheel, centrifugal of lever, concentrator bowl, the speed increasing gear group is by the wire wheel transmission of lay winding wire ropes, the final stage gear of speed increasing gear group and centrifugal wheel are fixed on the centrifugal wheel shaft, centrifugal of lever is fixed on the centrifugal wheel by pivot pin, then is fixed on the housing of high-building self-help instrument with centrifugal concentrator bowl that produces centrifugal action power and reaction force of lever.
