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.
