Anti-falling safety elevator

Abstract

The invention discloses an anti-falling safety elevator, which comprises an elevator shaft and an elevator car. The elevator shaft includes an elevator shaft and a buffer shaft. The elevator shaft is the elevator shaft when the elevator works normally. Below, just below the elevator shaft, the outer contour of the elevator car is tightly matched with the inner contour of the buffer shaft. The stroke of the buffer shaft is greater than one-third of the stroke of the elevator shaft. Connect to atmosphere via vent line. Under normal circumstances, the elevator car stops when it falls to the bottom of the elevator shaft. When the elevator falls, the elevator car falls into the buffer shaft, and the air in the buffer shaft is compressed to decelerate the elevator car until the speed is zero. Due to the buffer shaft The stroke is greater than one-third of the stroke of the elevator shaft, so the acceleration of the elevator can be reduced to a safe level when the elevator falls, effectively ensuring the safety of people taking the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator safety equipment, in particular to an anti-fall safety elevator. Background technique [0002] With the continuous increase of high-rise buildings, elevators have become an indispensable tool in people's lives. Elevators are convenient, fast, and energy-saving. Although the elevator technology is relatively mature and its performance is relatively perfect, potential safety hazards still exist, and various elevator accidents emerge in an endless stream, causing great injuries and economic losses. [0003] In elevator accidents, especially the sudden fall of the elevator, the damage to personnel is the greatest. The bottom of the existing elevator car is equipped with a buffer device, and the elevator shaft is also installed with a hard limit between each floor, which can provide protection when the elevator car falls. Certain buffering effect, but the buffering effect of the above-mentioned devic...
