Adjustable high-rise escape device

Abstract

The invention relates to an adjustable high-rise escape device, which is applied to temporary self rescue occasions when a high-rise emergency and a disaster occur, and comprises a metal structural box body. The adjustable high-rise escape device is characterized in that the box body is internally provided with a safety arrestment part, a guide rope part, a collecting rope part and a lifting and dropping slide part, a manual force adjusting telescopic link and a centrifugal clutch automatic force adjusting device are matched for arrestment, the guide rope part is internally provided with an automatic sequencing and winding mechanism for controlling a lifting and dropping rope, the collecting rope part is internally provided with an electric recovery unit, and the lifting and dropping slide is internally provided with a telescopic slide suitable for an escaper to stand on. The adjustable high-rise escape device is adjusted to drop with constant speed through a manual method or an automatic method by utilizing worm wheel and worm bar transmission and utilizing the weight of the escaper to generate dropping power, and is driven by a motor to return to a rescue site, thereby the quick and continuous escaping effect is realized. The invention has the advantages of strong sense of security of the escaper, small volume, easy storing, light weight as well as convenient conveying and installation in escaping.

Description

technical field [0001] The invention relates to an adjustable high-rise escape device, which is applied to high-rise emergency incidents and temporary self-rescue occasions when disasters occur, and belongs to the field of mechanical products. Background technique [0002] When a fire or other dangerous situation occurs in a high-rise building, residents in the building can quickly descend from the outdoors to escape from the window or balcony with the help of simple equipment and self-rescue, which is a relatively safe and fast way of escape. Existing various escape patents include more than one hundred escape devices and escape methods, such as gravity method, friction clutch type, hydraulic type, compressed air type, bucket truck type, manual self-service type, and gas cylinder energy storage type , electric type, friction wheel drum method and laser method, etc. Most of these devices are expensive, have poor operability in practical use, or require external energy source...

Problems solved by technology

Existing various escape patents include more than one hundred escape devices and escape methods, such as gravity method, friction clutch type, hydraulic type, compressed air type, bucket truck type, manual self-service type, and gas cylinder energy storage type , electric type, friction wheel drum method and laser method, etc. Most of these devices are expensive, have poor operability in practice, or need to rely on external energy, which is not conducive to maintenance, resulting in escape devices that cannot be popularized in most families. intrinsic meaning of the product

[0003] Chinese invention patent "Automatic speed-limiting high-rise escape device" (application number: 200810163860.1) discloses an automatic speed-limiting high-rise escape device. The advantage of rope length limit, its shortcoming is only by speed limit drum friction plate speed limit, manual braking device can not be controlled by the survivors themselves, the last survivor has the worst security; utility model patent "escape device for high-level distress" (application No.: 200420021816.4) An escape device, including an escape device composed of a damping deceleration part and an emergency braking part, a life-saving rope with a hook and an auxiliary part of a safety harness. The device has a rope inlet and a rope outlet Hole, using the principle of balance between friction and gravity in mechanics, through the braking hand brake, plays a role of rapid braking. Its disadvantage is that when the escape device falls and stalls, it cannot automatically limit the speed, cannot be used repeatedly, and has a poor sense of security. , low reliability; the high-rise building escape device described in the invention patent "Escape Device for High-rise Buildings" (application number: 96210964.9) includes a housing and a braking mechanism installed in it. The braking mechanism has a fishtail-shaped buffer at the tail The brake handle is installed on the connecting rod, which has double braking function. The disadvantage of this device is that the escape device cannot be used repeatedly, and the escapers have a poor sense of security.
