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 02267826 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, in practical applications, how to ensure that the deceleration of the person being carried remains within a certain range under various load conditions. At present, the problem of how to automatically adjust the deceleration has not yet been solved. The specific implementation of any escape device is critical

Embodiment Construction

[0032] Such as figure 1 Shown, this device is played by upper sprocket wheel (4), chain ladder (20), lower sprocket wheel (12), input sprocket wheel, makes the connection between upper connecting rod (34) and lower connecting rod (40) The effective stroke increases, and then the central angle of the balance wheel (29) rotates increases, and the damping force also increases, otherwise, the damping force decreases. Auxiliary balance spring (32) is promoted by balance wheel (29), and continuous suction and discharge energy play the balancing effect of motion.

[0033] Such as Figure 7As shown, the flexible lower bearing seat (13) is composed of an adjusting screw rod (10), a fixed screw rod (41), a fixed cover plate (42), a pressing plate (43), a spring (14), a bearing sleeve (15), a blind plate ( 44) and fork base (45) form. Among them, the bearing sleeve (15) is equipped with a spring (14), and the spring (14) has a pressing plate (43), all of which are embedded in the for...

Abstract

The emergency escape device for high rise building consists of jack ladder, guide track, chain wheel, speed varying mechanism, balance wheel speed regulating controller, etc. It is used for person in high rise building to escape in emergency. The present invention has the advantages of low cost, 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 balance-wheel speed-regulating type slow-down chain ladder escape device, which is suitable for people trapped on site when fires, earthquakes, or robbery occur in entertainment places, office buildings, apartments, and multi-storey residences. 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 multi-storey buildings are 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. Safe...
