Description

High-rise fire rapid-descent self-rescuer

Technical Field

The utility model relates to a high altitude device of saving oneself especially relates to a personnel's fast device that falls.

Background

With the continuous development of the productivity level of the human society and the acceleration of the urbanization process, the buildings are continuously developed towards centralization and high-rise. Limited by the restriction of the existing fire fighting means, when a fire disaster or an earthquake occurs in a high-rise building, the fire fighting rescue cannot enter a high-rise area to implement effective rescue at the first time. Due to uncertainty of rescue time, when an emergency disaster occurs in a high-rise building, serious casualties and property loss often occur. This requires that high-rise buildings need a safe, quick, easy to operate device that can save oneself in time when a dangerous situation occurs. At present, the mode that traditional gear reduction mechanism and friction reduction mechanism combined together is mostly used on the market, and the general structure of these devices is complicated, in case when mechanical failure, gear card are dead etc. uncontrollable factor, can't in time effectual put into the rescue. If a fault occurs on the way of the person descending, the loss will be immeasurable. Therefore, a safe, efficient and quick high-altitude self-rescue device is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a high-rise fire fast-descent self-rescuer.

A high-rise conflagration fast fall self-rescuer, including lifting hook, hawser and stay tube. The support pipe is internally and longitudinally movably provided with a suspension connecting rod, and the length of the suspension connecting rod is slightly longer than the section length of the support pipe so as to conveniently arrange a U-shaped suspension buckle. The U-shaped hanging buckle is fixedly connected with the hanging connecting rod, and the opening of the U-shaped hanging buckle is slightly larger than the section length of the supporting tube so as to facilitate the U-shaped hanging buckle to move on the supporting tube. A safety hole is formed in the U-shaped hanging buckle and used for hanging a safety rope.

The utility model discloses a rescue device, including stay tube, stand pipe, fixed winding has the stand pipe on the stay tube lateral wall, the fixed decelerator that is provided with in stand pipe both ends, decelerator be provided with and grip the handle, the one end that grips the handle is provided with the round hole that is used for fixed stay cord, the handle other end that grips is provided with eccentric camshaft, stay cord one end has hung the weight, the needs setting of weight is in the below of waiting to rescue people or thing, will fall to the ground earlier than personnel when the whereabouts. The eccentric camshaft is characterized in that a friction plate is arranged on one side of the extending portion of the eccentric camshaft, a return spring is arranged in the middle of the holding handle, the other end of the return spring is fixed on the outer wall of the guide pipe, and the cable penetrates through the guide pipe and the speed reducing device.

Further, the guide pipe is wound on the support pipe at least one turn.

Furthermore, the lifting hook is hooked on the supporting arm.

Furthermore, the supporting arm is arranged on the balcony wall and can be folded on the surface of the wall. When the support arm is not used, the support arm is folded on the wall surface, so that the support arm is attractive and does not occupy space; in use, the support arms are deployed to provide support.

The utility model discloses a theory of operation: (1) when in use, the rescued person A can hang the lifting hook 1 at one end of the utility model on the supporting arm of the wall body, and the lifting hook at the other end passes through the balcony to be thrown (or fixed) to the ground. The safety rope to be worn by the rescuee passes through the safety hole to be fixed with the utility model. Then, the balcony is turned over for jumping down. In the falling process, the weight pulls the holding handle of the speed reducer through the weight of the weight, and then the eccentric cam shaft is opened, so that the friction plate is separated from the cable in the guide pipe, and the speed reducer can fall.

(2) Because there is frictional force between hawser and the stand pipe, the utility model discloses a fixed stand pipe of twining certain number of turns in the back shaft outside for increase the actual friction area of hawser and stand pipe, the gravity that produces with the help of the frictional force that produces between the two balances or offsets people or heavy object, makes at the in-process people or heavy object that fall down with at the uniform velocity or less acceleration whereabouts.

(3) Because the weight is in by the certain distance in rescue person below, the weight can fall to the ground earlier with by the rescue person, the weight after falling to the ground loses the effect to the stay cord, therefore the pulling force that the weight was exerted on holding the handle disappears, reset spring will hold the handle jack-up and reply original position, holding the handle this moment just can begin to extrude its inboard hawser, the hawser receives the frictional force of direction pipe wall and the extrusion force of holding the handle simultaneously, the resultant force of its resistance that receives will exceed the dead weight of whole system, can produce an ascending resistance along the hawser, this resistance just can force a dress rescue device to slow down, make by the rescue person safe landing. The deceleration control of the whole rescue device is controlled by the landing time of the weight, the landing time of the weight is determined by the pull rope on the weight, and the longer the pull rope is, the earlier the weight lands, and the earlier the braking effect starts. The length of the heavy hammer can be properly adjusted according to the physical knowledge by combining the actual situation so as to better realize the rescue purpose.

(4) After the rescued person A arrives at the ground, the safety rope is unfastened and fixed on the ground by the lifting hook. The rescued person B, C.

Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings.

Referring to fig. 1-4, the fast-falling self-rescuer for high-rise fire comprises a lifting hook 1, a cable 2 and a support pipe 3. The hook 1 is hooked on a support arm 10, and the support arm 10 is arranged on the wall 4 of the balcony 40 and can be folded on the surface of the wall 4. The support tube 3 is longitudinally and movably provided with a suspension connecting rod 31, and the length of the suspension connecting rod 31 is slightly longer than the section length of the support tube 3 so as to conveniently arrange a U-shaped hanging buckle 32. The hanging connecting rod 31 is fixedly connected with a U-shaped hanging buckle 32, and the opening of the U-shaped hanging buckle 32 is slightly larger than the section length of the supporting tube 3 so as to facilitate the movement of the hanging buckle on the supporting tube 3. The U-shaped hanging buckle 32 is provided with a safety hole 320, and the safety hole 320 is used for hanging a safety rope.
