Abstract

The invention relates to a high-rise escape device which comprises a chassis and a rotating disk wound with a steel wire rope, wherein a one-way clutch and a speed control mechanism are mounted in the chassis; a support shaft on one side of the one-way clutch extends out of the chassis and is linked with a rotating shaft of the rotating disk; the speed control mechanism comprises a friction braking and rotational speed regulating component and a gear rotational speed regulating component; the friction braking and rotational speed regulating component comprises a stepped shaft, a centrifugal clutch and a first gear with an internal thread; an outer ring of the centrifugal clutch is an outer gear; the gear rotational speed regulating component comprises a second gear, a third gear and a backstop device; an auxiliary shaft is rotatably mounted in the chassis; the second gear, the third gear and the backstop device are mounted on the auxiliary shaft; the backstop device is positioned between the second gear and the third gear; the second gear is meshed with the outer gear; and the first gear is meshed with the third gear. The invention provides the high-rise escape device which is high in reliability, convenient for mounting and stable for working.

Description

technical field [0001] The invention relates to emergency auxiliary equipment, in particular to a high-rise escape device. Background technique [0002] Existing high-rise escape device technology mainly contains two forms of electric drive and pure machinery. The reliability of electric-driven high-rise escape devices is greatly reduced due to the power failure caused by the fire itself. The purely mechanical high-rise escape device has significant advantages because it does not need electric drive and can still work effectively in a fire. There are many technologies about purely mechanical high-rise escape devices, but there are few practical ones. As for those available on the market, they are even rarer, and the degree of approval for such existing products is generally not high. [0003] After analyzing the existing domestic and foreign patents and products on the market, it is concluded that the existing technology mainly has the following problems: [0004] (1) The...
