Self-adaptive gravity high-rise fire escape rope forced landing device

Abstract

The invention relates to a self-adaptive gravity high-rise fire escape rope forced landing device. The self-adaptive gravity high-rise fire escape rope forced landing device comprises an outer shell,an inner shell embedded into the outer shell, an elastic part and at least one brake part. The inner shell and the outer shell are slidably connected in at least one direction. The elastic part is connected to the inner shell and the outer shell to apply an acting force opposite to the sliding direction of the inner shell and the outer shell. The brake part comprises a movable part connected to arope winding plate to conduct a torque and a brake part for applying a reverse action force to the movable part. The brake part is connected to the outer shell, the movable part is connected to the inner shell, or the brake part is connected to the inner shell, and the movable part is connected to the outer shell, so that the brake part and the movable part shifts and / or deviates along with slideof the inner shell and the outer shell so as to change the action force between the brake part and the movable part. Therefore, the resistance of a rope pulled out in the device is positively relatedto the weight of a forced lander, and the falling speed difference of forced landers with different weights is controlled to decrease.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an adaptive gravity high-rise fire escape rope forced landing device. Background technique [0002] At present, the traditional high-rise fire escape forced landing device mainly includes two kinds of fixed resistance type and resistance manual adjustable type. Among them, the fixed resistance type high-rise fire escape 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 landings, which will lead to slow decline for those with small weights and slow down for those with heavy weights. The rapid descent, or the lack of gravity due to the small body weight directly lead to the failure to make a forced landing. However, the resistance manual adjustable high-rise fire escape emergency landing device generally needs to set the resistance when the rope is pulled out according to its own weight,...

Among them, the fixed resistance type high-rise fire escape 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 landings, which will lead to slow decline for those with small weights and slow down for those with heavy weights. The rapid descent, or the lack of gravity due to the small body weight directly lead to the result of being unable to make a forced landing

The resistance manual adjustable high-rise fire escape emergency landing device generally needs to set the resistance when the rope is pulled out according to its own weight, or often requires two people to cooperate to complete it, one is tied to the rope to descend, and the other manually controls the rope in real time. Although this manually adjustable high-rise fire escape forced landing device can adjust the resistance when the rope is pulled out according to the weight of the forced lander, so that the landing speed of the forced lander can be controlled to a certain extent, but in the emergency of a fire Under such circumstances, people usually cannot make accurate judgments and quickly operate equipment that is not frequently used, which makes the escape efficiency low and easily delays the timing of escape in a fire
