The invention discloses an elevator landing door safety protection method based on induction and trigger. The method is characterized in that an induction switch is mounted on a landing door ground strip, meanwhile, a trigger switch is mounted on a car, only after the car moves to the landing door and is in place, the trigger switch on the car enables the induction switch to act, a control signalis sent to a control center, and the landing door can be driven by a car door to be opened. An electronic digital safety lock can be additionally arranged in a control circuit. By means of the method,the problem that few safety measures for elevator landing doors are achieved at present can be fundamentally solved, and the opening safety of the landing door can be greatly improved. Meanwhile, safety performance generated during maintenance and after maintenance can be improved.
一种基于感应触发的电梯层门安全保护方法,其特征是在层门地条上安装一感应开关,同时在轿厢上安装上触发开关,只有轿厢移动到层门并到位后,轿厢上的触发开关使感应开关动作并发出控制信号到控制中心,轿厢门才能带动层门打开;在控制电路中还可增设电子数字安全锁。本发明的能从根本上改善目前电梯层门安全措施少的问题,能大大提高层门开启的安全性。同时还能提高检修时和检修后的安全性能。
