Abstract
The utility model discloses a device for automatically controlling speed of a self-rescuer of high buildings. The device comprises a centrifugal wheel, a lever-type centrifugal block, and a centrifugal sleeve. The centrifugal wheel is driven by a wire wheel enwound with cable wires; 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 device can control the falling speed of the self-rescuer of high buildings full-automatically and is used conveniently and safely.
Description
Technical field
The utility model relates to a kind of high-building self-help instrument, but special relevant with the apparatus structure of its Automatic Control speed.
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 automatic control velocity device of high-building self-help instrument, with the decrease speed of Automatic Control portable high-building self-help instrument, makes high-building self-help instrument use more convenient, safety.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of automatic control velocity device of high-building self-help instrument, form by centrifugal wheel, centrifugal of lever, concentrator bowl, centrifugal wheel is by the wire wheel transmission of lay winding wire ropes, 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.
Increase by a gear up mechanism in the said apparatus, gear up mechanism is by the wire wheel transmission of lay winding wire ropes, and the final stage gear and the centrifugal wheel of gear up mechanism are fixed on the centrifugal wheel shaft.
Have internal gear in the above-mentioned wire wheel, the internal gear of wire wheel is transmitted in the chopped-off head gear of gear up mechanism.
Set up brake block between centrifugal of above-mentioned concentrator bowl and the lever.
The outer wall of above-mentioned concentrator bowl and centrifugal brake block friction place is provided with cooling medium, is used to absorb the heat that the friction plate on centrifugal of the lever produces, and reduces the temperature of concentrator bowl.
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, 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 is at concentrator bowl, produce the rotation of centrifugal of frictional force obstruction lever, hinder the payingoff speed of wire wheel again by centrifugal wheel, 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 right view of Fig. 1.
The specific embodiment
Seeing also shown in Figure 1ly, is preferred embodiment of the present utility model, has disclosed a kind of automatic control velocity device of high-building self-help instrument, mainly is made up of centrifugal wheel 5, centrifugal 6 of lever, concentrator bowl 9.
Each member annexation is: centrifugal wheel 5 is by wire wheel 3 transmissions of lay winding wire ropes 10, has internal gear 31 among this embodiment in the wire wheel 3, also increase a gear up mechanism 4 (forming) in the device by three gears 41,42,43, the internal gear 31 of wire wheel 3 is transmitted in the chopped-off head gear 43 of gear up mechanism 4, the final stage gear 41 of gear up mechanism 4 and centrifugal wheel 5 are fixed on the centrifugal wheel shaft 8, are improved the rotating speed of centrifugal wheel 5 by gear up mechanism 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.
Among this embodiment, between concentrator bowl 9 and lever-type centrifugal 6, set up brake block 63, referring to Fig. 2, to increase friction.Concentrator bowl 9 is provided with cooling medium 91 with the outer wall of centrifugal 6 brake block friction place, is used to absorb the heat that the friction plate on centrifugal 6 of the lever produces, and reduces the temperature of concentrator bowl.
The utility model is simple in structure, compact, can apply in the various high-building self-help instruments.When disaster comes, an end that steel wire rope 10 is stretched out housing 2 fixes, can be fixed in the room by hook 12, 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, 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, and centrifugal action is at concentrator bowl 9, the rotation that generation frictional force obstruction lever is centrifugal 6, hinder the payingoff speed of wire wheel 3 again by centrifugal wheel 5, high-building self-help instrument is descended with certain speed, thereby reach the purpose of automatic control escape personnel's decrease speed.
