Abstract
The utility model discloses a device for manually controlling speed of a self-rescuer of high buildings. The device comprises a shell, a wire cable, a wire wheel, a live shaft, a centrifugal wheel, a brake handle, a reduction torsion spring and a brake block. One end of the wire cable extends out of the shell, and the other end is enwound and fixed on the wire wheel which drives the centrifugal wheel through the live shaft; the brake handle is arranged on the shell through a pin shaft; the reduction torsion spring is arranged between the handle and shell; and the brake block which is pushed and pressed by the handle to generate braking on the centrifugal wheel is arranged on the handle. The device can control the setting out speed of the self-rescuer of high buildings manually and is used conveniently and safely.
Description
Technical field
The utility model relates to a kind of high-building self-help instrument, and especially manually the apparatus structure of control rate is relevant with it.
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.
In the society there being much existing high-rise life saving mode, such as tiltedly rope downhill race escape, is to fasten with long rope one end 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, be the friction control unwrapping wire between the armrest palm and the rope, some needs distress personnel to run quickly toward roof, because offered the security against fire road junction on roof, 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, promptly by the control of the friction between human body and rope unwrapping wire.
In a word, high-building self-help instrument of the prior art uses all very inconvenient, and, in the escape process, manual adjustments decrease speed voluntarily, safety in utilization has much room for improvement.
The utility model content
Main purpose of the present utility model is to provide a kind of manual control rate device of high-building self-help instrument, and it is easy to use, safe and can manually control the payingoff speed of high-building self-help instrument.
In order to reach above-mentioned purpose, solution of the present utility model is:
The manual control rate device of high-building self-help instrument, mainly form by housing, steel wire rope, wire wheel, turning cylinder, centrifugal wheel, brake lever, reduction torsion spring and brake shoes, one end of steel wire rope stretches out outside the housing, the other end twines and is fixed on the wire wheel, wire wheel is transmitted in centrifugal wheel by turning cylinder, brake lever is contained on the housing by bearing pin, is provided with reduction torsion spring between handle and the housing, is equipped with on the handle to promote to be pressed on the brake shoes that produces braking on the centrifugal wheel by handle.
Increase by a gear up mechanism in the said apparatus, have internal gear in the wire wheel, the internal gear of wire wheel is transmitted in the chopped-off head gear of gear up mechanism, and the final stage gear and the centrifugal wheel of gear up mechanism are fixed on the turning cylinder.
After adopting said structure, the utility model is simple in structure, can apply in the various high-building self-help instruments.When disaster comes, an end of steel wire rope is fixed, shoulder this high-building self-help instrument then and jump downwards, the escape personnel is rotated by steel wire rope pulling wire wheel by self gravitation in the decline process, is transmitted in centrifugal wheel.When desiring manually to control payingoff speed, can firmly hold handle, brake shoes is promoted to be pressed on the centrifugal wheel by handle, centrifugal wheel plays the brake drum effect, hindering wire wheel by centrifugal wheel through turning cylinder again rotates, the control payingoff speed is realized hand-operated brake, thereby reaches the purpose of manual adjustments decrease speed voluntarily by the escape personnel.The utility model makes various high-building self-help instruments 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
See also illustrated in figures 1 and 2, it is preferred embodiment of the present utility model, disclosed a kind of manual control rate device of high-building self-help instrument, mainly formed by housing 2, steel wire rope 10, wire wheel 3, turning cylinder 8, centrifugal wheel 5, brake lever 111, reduction torsion spring 114 and brake shoes 112.
Wherein, an end of steel wire rope 10 stretches out outside the housing 2, can have steel hook 12, makes things convenient for an end of steel wire rope 10 to fix, and the other end of steel wire rope 10 twines and is fixed on the wire wheel 3.
Brake lever 111 is contained on the housing 2 by bearing pin 113.
Be provided with reduction torsion spring 114 between handle 111 and the housing 2, brake shoes 112 is housed on the handle 111, and handle 111, brake shoes 112, bearing pin 113 constitute manual governing device 11, and brake shoes 112 can be promoted to be pressed on the centrifugal wheel 5 by handle 111, realize hand-operated brake, the manual adjustments decrease speed.
The utility model is simple in structure, can apply in the various high-building self-help instruments.
When disaster comes, be that the end with steel wire rope 10 fixes by the steel hook 12 on it, shoulder this high-building self-help instrument then and jump downwards, the escape personnel is rotated by steel wire rope 10 pulling wire wheels 3 by self gravitation in the decline process, is transmitted in centrifugal wheel 5.
When desiring manually to control payingoff speed, can firmly hold handle 111, brake shoes 112 is promoted to be pressed on the centrifugal wheel 5 by handle 111, hindering wire wheel 3 by centrifugal wheel 5 through turning cylinder 8, gear up mechanism 4 again rotates, the control payingoff speed, realize hand-operated brake, thereby reach the purpose of manual adjustments decrease speed voluntarily by the escape personnel.If desire is accelerated payingoff speed, only need to decontrol the hand of holding handle 111 and get final product.
The utility model makes various high-building self-help instruments easy to use, and it is safer to land.
