Problems solved by technology

Patent CN1212167A proposes a rotary high-rise building life-saving ladder, which uses a rope ladder to descend slowly, and its stability and operability are also difficult to meet actual needs
The utility model patent 2267826 proposes a high-rise escape device, which is transmitted by a single chain structure, and its balance and deformation caused by long-term placement are also difficult to enter the practical state.
From a technical point of view, the analysis of some schemes that adopt centralized and orderly slow down does not raise the issue of how to automatically adjust the slow down, and how to ensure that the speed of the person being carried is always slowed down under various load conditions in practical applications. kept within limits, this technique is critical to the specific implementation of any abort device

Embodiment Construction

[0028] As shown in Figure 1, the device is composed of upper and lower sprockets (4, 12), chain ladder (20), input sprocket shaft (7), flexible lower bearing seat (13), hydraulic oil tank (1), speed change mechanism (6 ), a hydraulic speed-regulating controller (2), a generator (3) and a blower fan (16) that is located at the entrance and is powered by the motor (3) through the cable (11) to form. Wherein the chain ladder (20) is vertically installed in the emergency escape passage reserved by the high-rise building, and its guide rail (19) is fixed on the wall of the passage. Two upper sprockets (4) are respectively arranged on both sides of the top of the guide rail (19), and two lower sprockets (12) are respectively arranged on both sides of the bottom of the guide rail (19), and the upper and lower sprockets on each side are jointly engaged with a chain (9) .

[0029] As shown in Figures 2 and 3, the chain ladder (20) is made up of guide rail (19), special-shaped piece (1...

Abstract

The emergency escape device for high rise building consists of jack ladder, guide track, chain wheel, speed varying mechanism, hydraulic speed regulating controller, etc. It is used for person in high rise building to escape in emergency. The present invention has the advantages of no need of outer driving force, relatively smooth lowering speed and no floating motion.

Description

Technical field [0001] The invention relates to an escape device for multi-storey buildings, in particular to a hydraulic speed-adjustable slow-down chain ladder escape device, which is suitable for fire, earthquake or robbery in entertainment places, office buildings, apartments, multi-storey residences, etc. In the case of helplessness, the chain ladder escape device of the present invention can safely escape from dangerous situations. Background technique [0002] How to solve the problem of safe escape of trapped people on the scene when a high-rise building is in distress has always puzzled researchers in construction and fire departments. So far, there are almost no ideal products that have been put into practical use. People have put forward some solutions to the problem from various aspects, some of which use ropes to descend slowly, and some use buffers to directly land. These are all individual escape behaviors. Safety and operability are not ideal. Chaos ensues ...
