Problems solved by technology

[0002] At present, when a fire breaks out, people will choose to use safe passages to escape, but the safe passages are located inside the building. Compared with the outdoor escape passages, the indoor ventilation circulation is poor, so it is safer to use the outdoor escape passages, and the outdoor escape passages are often basically used. Fixed frame structure, but cannot realize lifting and disassembly functions, so it is necessary to design a liftable and detachable escape staircase

specific Embodiment approach

[0021] As an improved specific embodiment, the drive assembly includes a rope 22, a winding wheel 21, a winding motor 20 and a reversing wheel 23, and the reversing wheel 23 is rotatably installed on the roof, and the rewinding wheel 21 and The driving motor is driven and connected, the rope 22 is passed around the reversing wheel 23, and one end is fixed on the winding wheel 21, and the rope 22 can be wound on the winding wheel 21, and the other end is connected to each floor. The upper pedal 50 is fixed by the fixing block 220.

[0022] After the crimping motor 20 is turned on, the rope 22 is driven to shrink, and after being reversed by the reversing wheel 23, the upper pedal 50 fixed on the rope 22 by the fixed block 220 is stretched upwards, thereby extending the escape ladder.

[0023] As an improved specific embodiment, the upper pedals 50 on each floor are assisted to move through a sliding assembly, and the sliding assembly includes a chute 3 fixed on the building ext...

Abstract

The invention discloses an escape stair for an outer wall. According to the technical scheme, the escape stair is characterized by comprising upper fire escape exits, lower fire escape exits and escape ladders, wherein the upper fire escape exits and the lower fire escape exits are formed in all floors, and the escape ladders are erected at the outer ends of the upper fire escape exits and the lower fire escape exits; and the escape ladders are fixed to a driving assembly and sequentially connected end to form an open chain structure, every two adjacent escape ladders can be driven by the driving assembly to rotate relatively, and the whole escape ladders can be switched between a folded state and an unfolded state.

Description

technical field [0001] The invention relates to the field of escape stairs, in particular to an escape staircase for exterior walls. Background technique [0002] At present, when a fire breaks out, people will choose to use safe passages to escape, but the safe passages are located inside the building. Compared with the outdoor escape passages, the indoor ventilation circulation is poor, so it is safer to use the outdoor escape passages, and the outdoor escape passages are often basically used. The fixed frame structure cannot realize the lifting and dismounting functions, so it is necessary to design a liftable and detachable escape staircase. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a liftable and detachable escape staircase for external walls. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] This escape staircase for...
