基于电梯开关门新型安全保护装置研究与设计

电梯门锁结构中电气触头常会出现短接等问题,导致电梯门还未完全关闭,电梯便开始运行,从而引发了剪切事故和坠落事故。针对这些问题提出了一种新安全保护装置,本装置采用增加一个有高速开关二极管控制的电路与电气触头形成一种双重保障,从而保证电梯安全有效的运行。

The electrical contact in the structure of elevator door lock often has problems like short circuit and so on, which leads the elevator door to be not completely closed, and the elevator will start to run, thus causing the shear accident and fall acci-dent. Aiming at these problems, a new kind of safety protection device is put forward. In this device, an additional circuit controlled by high speed switch diode and electric contact are added to form a kind of double guarantee, so as to ensure the safe and effective operation of the elevator.
