The invention discloses a safety protection method for an elevator landing door. The safety protection method is characterized in that a laser infrared emitting-receiving unit is additionally arrangedon a car door, wherein while the car door drives the landing door to close, an infrared laser emitting unit of the car door scans a car door neutral position from top to bottom, and door closing is immediately stopped and the door returns if blocking occurs, so that car door movement is completely scanned without mission and a dead corner, a user is free of a feeling, and door closing safety is ensured. An electronic digital safety lock further can be additionally arranged in a control circuit. Safety measures of the safety protection method can radically improve the problem that current safety measures for the elevator landing door are a few, can greatly improve landing door opening safety, and further can improve safety performance during maintaining and after maintaining.
一种电梯层门安全保护方法,其特征是在轿厢门上增设激光红外发射接收单元,当轿厢门带动层门关闭时,轿厢门的红外激光发射单元自上而下对轿门空档进行扫描,如有阻断则立即停止关门并退回;从而实现轿门移动成面扫描,无遗漏,无死角,用户无感觉,确保关门安全。在控制电路中还可增设电子数字安全锁。本发明的安全措施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。
