Title
(EN) Interlock device for elevator
(ZH) 电梯的联锁装置
Abstract
(EN)
In an elevator interlock apparatus, a catch is disposed on a landing entrance, and a latch is disposed on a landing door. The latch engages with the catch and prevents movement of the landing door in a door opening direction when the landing door is in a fully-closed state. A release detector detects whether or not the latch is in a position engaged with the catch by detecting a change in a magnetic field without contacting the latch.

(ZH)

在电梯的联锁装置中,在层站出入口处设有挂钩,在层站门上设有门闩。门闩在层站门为全闭状态时与挂钩卡合,以阻止层站门向开门方向移动。解锁检测器通过检测磁场的变化,以与门闩不接触的方式来检测门闩是否位于与挂钩卡合的位置。
