A vertical elevator anti-falling device and a vertical elevator for preventing people from falling

Abstract

The invention discloses a people-falling-prevention device for vertical elevator. The device comprises an upper falling prevention layer and a lower falling prevention layer which are vertically stacked. Therefore, an upper layer cable and a lower layer cable of the people-falling-prevention device are interwoven into a net-shaped structure which is arranged on the cross section of an elevator shaft to block and bear objects, especially people falling from upstairs carelessly. When a lift car descends, the bottom of the lift car presses a first single-way turning over rod and a third single-way turning over rod downwards, the outer end of a first lever and the outer end of the third lever warp up to drive an upper winding roll and a lower winding roll to rotate, the upper layer cable and the lower layer cable are wound until the upper layer cable and the lower layer cable retreat from the elevator shaft, the lift car can smoothly pass through the elevator shaft, and then the upper layer cable and the lower layer cable return to the initial positions under the pull-back effect of an upper cable pulling back device and a lower cable pulling back device. When the lift car ascends, the action principle is the same as the principle adopted when the lift car descends. Therefore, the people-falling-prevention device can ensure life and property safety of people and effectively avoid personnel casualty. The invention further discloses a vertical elevator preventing people falling based on the people-falling-prevention device.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an anti-falling device for a vertical elevator and a vertical elevator for preventing people from falling. Background technique [0002] Elevators are generally used in urban high-rise buildings at present, but existing elevator designs have hidden dangers in safety protection. The elevator is an automation product that combines electrical control and mechanical transmission. Naturally, there will be failures such as aging of electrical parts, failure of control, and failure of mechanical wear and tear. One of the faults of the elevator is to open the elevator door without the car. When people are inattentive, poor in sight, etc., they will enter the elevator shaft and cause an accidental fall; If there is no equipment inside to hinder the movement of the car, the following elevator accidents will occur: [0003] 1. When the elevator fails, the elevator door will open automatically or ...

AI Technical Summary

Problems solved by technology

[0003] 1. When the elevator fails, the elevator door will open automatically or be easily opened, and people will easily fall into the elevator shaft without paying attention, causing casualties;

[0004] 2. When the elevator fails, the maintenance personnel cannot know which floor the car is parked on. When they need to check one by one, opening the elevator door will also cause an accident to fall into the elevator shaft, causing casualties;

[0005] 3. When people forcefully open the elevator door, people will fall into the elevator shaft; for example, if a drunk person forces the elevator door to open, the drunk person will fall into the elevator shaft, causing casualties
