在电梯的正常启动运行条件中,无论是各层站的层门(又称厅门),或者轿门(包括贯通式或称通道式时的前后轿厢门),还是井道安全门,都被确认处于关闭状态,只有满足了该条件,电梯才能正常启动运行,这就是人们熟悉的“门联锁”安全保护,通过电气开关的触点联锁线路,门锁装置等实现。门联锁涉及电梯的门户开启和电梯启动运行条件,以“一统天下”作比喻应当是恰当的。
In the normal starting and running conditions of the elevator, whether it is the landing door (also known as the hall door), or the car door (including through-type or channel-style front and rear car door), or hoistway safety doors are confirmed Is closed, only to meet the conditions, the elevator can start running normally, which is familiar “door interlock ” security protection, through the electrical switch contact interlock lines, door locks and other devices to achieve. Door interlock involves the elevator door open and elevator start running conditions, “dominate the world ” metaphor should be appropriate.
