Abstract
The utility model provides an unpowered auto-circulation escape ladder. A damping retarding mechanism and a sprocket gear train are provided on the upper part of the main frame of the escape ladder and form a transmission counter; a circulation chain mechanism is provided on the facade of the main frame, a recirculation chain and a foot board. The chain mechanism and the damping retarding mechanism form the transmission counter via the sprocket gear train, and the transmission counter can drive the chain mechanism and the foot board rolling back and forth under self-weight of human bodies. The main frame is provided with a plurality of bridge approaches connected with the chain mechanism in sections. The utility model can transmit to the damping retarding mechanism in the mechanism to control the chain combination and the foot board via a drive sprocket and a driven sprocket relying on the self-weight of human bodies without external power, and transport the people trapped rapidly at a uniform speed and in an uninterrupted way. The utility model is high in transport efficiency, safe and reliable, and suitable for various new and reconstructed high-rise and low-rise architectures, especially for adding fireproof passages in narrow buildings without fireproof passages.
Description
Technical field:
The utility model relates to a kind of improvement of the flame proof passageway building of skyscraper, and a kind of unpowered automatic circulation safety ladder especially is provided, and belongs to high-low storey building fire life-saving equipment technical field.
Background technology:
Existing high low layer flame proof passageway all adopts traditional staircase structure, when meeting accident dangerous situation, personnel are by the stair escape of running downwards, because stair are easily by the pyrotechnics shutoff, which floor trapped personnel do not run just to can't run, suffocated by pyrotechnics, be eager to escape easily produces extruding mutually in addition, causes life danger.
Summary of the invention:
The utility model provides a kind of unpowered automatic circulation safety ladder, and when having solved existing high lower building and meeting accident dangerous situation, passway for escaping is stranded stifled, evacuates shortcomings such as danger.
The utility model solution is as follows: be provided with damping reducing gear and sprocket system on the body frame top of safety ladder and constitute transmission, circulation link chain mechanism is located at the body frame front, reciprocation cycle chain and pedal are installed on it, link chain mechanism and damping reducing gear constitute transmission by sprocket system, but chain drive-belt mechanism and pedal under the body weight effect, the rolling that moves in circles, the body frame structure supports by base support or by arm, by means of the fixing dual mode in building side.
In the setting height on the body frame, segmentation is provided with an access bridge to body frame front chain combination pedal place, the people continuously can be evacuated to ground.
The utility model in use, in case dangerous situation occurs, trapped personnel makes up the pedal place by every floor access bridge to body frame front chain, set foot on the pedal balancing pole of holding, the circulation link chain combination begins at the uniform velocity to descend by body weight, reciprocation cycle realizes uninterruptedly trapped personnel being delivered to ground continuously.
The utility model good effect is, under any complicated adverse circumstances, need not external impetus, by body weight can be by drive sprocket, reached the internally-damped reducing gear of main frame control chain combination and pedal by movable sprocket, at the uniform velocity incessantly trapped personnel is transported to ground rapidly, the transfer efficiency height, safe and reliable, be applicable to various high-low storey buildings newly-built, reconstruction, be particularly useful for narrow no flame proof passageway building and set up flame proof passageway.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
The specific embodiment:
According to shown in Figure 1, the damping reducing gear on the top of the body frame 1 of safety ladder adopts conventional high-rise descending lifeline 2, by drive sprocket 3, formed sprocket system by movable sprocket 4, constituted transmission by movable sprocket 4 and descending lifeline 2, body frame 1 bottom also is provided with train 7, two circulation link chains 5 are installed in parallel in and constitute the chain movement pair on drive sprocket 3 and the train 7, be separated by between the circulation link chain 5 1.5～2.0 meters and be horizontally arranged with some pedals 6, chain 5 constitutes transmission with descending lifeline 2 by drive sprocket 3, when the people steps on pedal 6, by the rolling that moves in circles of himself weight-activated chain and pedal, body frame 1 structure supports by base support or by arm, by means of building fixedly dual mode of side.
Claims (3)
1, a kind of unpowered automatic circulation safety ladder, it is characterized in that: be provided with damping reducing gear and sprocket system on the body frame top of safety ladder and constitute transmission, circulation link chain mechanism is located at the body frame front, reciprocation cycle chain and pedal are installed on it, link chain mechanism and damping reducing gear constitute transmission by sprocket system, but chain drive-belt mechanism and the pedal rolling that moves in circles under the body weight effect.
2, the described safety ladder of claim 1 is characterized in that: segmentation is provided with some access bridges that are connected with link chain mechanism on body frame.
