Multiuser high-rise building fire escape device

摘要

A multiuser high-rise building fire escape device includes a basic bearing frame assembly (1) alternatively mounted on the roof or either floor of a high-rise building, and several cabins (2,2′) mounted on the tracks of the basic bearing frame assembly (1) and suspended therefrom through a steel rope combination (20). The cabins (2,2′) each comprises a speed reducing gear (3) to smoothen the down stroke speed of the cabin (2,2′), a motor assembly (4) to drive the steel rope (20) to wind up so as to lift the cabin (2,2′), a mid-way stop mechanism (5) to stop the cabin (2,2′) during down stroke, and a ladder door (26) to control the access of the cabin (2,2′) and to serve as a bridge for striding over the cabin (2,2′) and an intermediate floor of a building.
