Elevator protective net and anti-wind net draw-in structure thereof

Abstract

The invention discloses an elevator protective net and an anti-wind net draw-in structure thereof. The elevator protective net comprises draw-in gears, two or more guide wheels and gear covers. The draw-in gears and the guide wheels are arranged in the gear covers; the gear covers are at least provided with side edge openings; the draw-in gears are arranged in the middles of the side edge openings, and the draw-in gears are exposed outside the side edge openings; and the two or more guide wheels are located on the two sides of the draw-in gears correspondingly. Thus, winding of the protective net in the process of draw-in or unfolding is prevented, when an elevator landing door loses efficacy, the protective net can be smoothly unfolded at the corresponding elevator landing door to prevent people from entering a hoistway, the people is prevented from falling into the hoistway, and personal safety is guaranteed.

Description

technical field [0001] The invention relates to an elevator protective net and an anti-winding net collection structure thereof. Background technique [0002] An elevator is a vertical lift powered by a motor, equipped with a car, and used in multi-storey buildings to take people or carry goods. As a means of transportation in high-rise buildings, elevators bring great convenience to people's lives, but at the same time, taking elevators also contains great risks, and accidents occur that threaten people's lives. There are many factors that make the elevator unsafe, but the most harmful one is the falling accident of the shaft, which directly causes casualties. Most of the reasons are the failure of the elevator door mechanism, or artificial illegal operation, which causes the car to not be on the floor. The elevator door accidentally opens and the passenger or staff slips and falls into the well, causing personal injury accidents. [0003] At present, the anti-fall protec...

Problems solved by technology

There are many factors that make the elevator unsafe, but the most harmful one is the falling accident of the shaft, which directly causes casualties. Most of the reasons are the failure of the elevator door mechanism, or artificial illegal operation, which causes the car to not be on the floor. The elevator door accidentally opens and the passengers or staff fall into the hoistway by accident, causing personal injury accidents.

[0003] At present, the anti-fall protection device of most elevators adopts mechanical type or protective net type, but the safety factor of mechanical protective device is low, and requires frequent manual maintenance, which not only brings trouble to use, but also causes waste of resources; protective net type The protection device is easy to entangle the protective net during the net collection process, so that when the elevator door fails, the protective net cannot be smoothly deployed at the corresponding elevator hall, resulting in the loss of the protective effect of the protective net
