Abstract

The invention relates to a brake device of self-adaptive weight high-rise fire escape rope emergency landing equipment. The brake device comprises an outer shell, an inner shell nested in the outer shell, elastic parts and a brake part, wherein the inner shell is in sliding connection with the outer shell in at least one direction; the elastic parts are connected with the inner shell and the outershell so as to apply action force opposite to the sliding direction of the inner shell and the outer shell; the brake part is fixedly connected onto the outer shell or the inner shell and is used forchanging the size of resistance applied to the rope when the rope is pulled out according to the size of relative sliding displacement between the inner shell and the outer shell. Through such arrangement, the resistance generated when the rope in the self-adaptive weight high-rise fire escape rope emergency landing equipment adopting the brake device is pulled out is positively correlated with the weight of emergency landing people so as to control the landing speed difference of the emergency landing people with different weights to be reduced.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a brake device for an adaptive gravity-adapted high-rise fire escape rope forced landing equipment. Background technique [0002] At present, the braking device of the traditional high-rise fire escape rope emergency landing device mainly includes two kinds of fixed resistance type and manual adjustable resistance type. Among them, the fixed resistance type high-rise fire escape rope forced landing device has a fixed resistance when the rope is pulled out. This method cannot well adapt to the different weights of the forced landing person, which will lead to slow decline for small weight and heavy weight. The rapid descent of the aircraft, or the lack of gravity due to its small weight directly lead to the result that it cannot be forced to land. However, the manually adjustable resistance rope emergency landing device for high-rise fires generally needs to set the resistance ...
