The invention discloses an elevator door lock safety anti-trapping system which comprises a conventional door lock loop connected with an elevator host controller in series and a standby door lock loop provided with a change-over switch and connected with the conventional door lock loop in parallel, and the standby door lock loop and the conventional door lock loop are connected into a door lock safety system through the change-over switch. The contact directions of the conventional door lock switch and the standby door lock switch of the same car door or landing door are perpendicular to each other in space. The contact directions of the contacts of the conventional door lock loop and the standby door lock loop are set to be perpendicular to each other, when the elevator runs and the conventional door lock loop breaks down, a standby door lock switch does not break down at the same time, and therefore the standby door lock loop is switched rapidly, the elevator runs to the flat layer position again, and passengers are rescued to leave an elevator car. And maintenance personnel do not need to wait for on-site rescue for a long time, and rapid and safe rescue is achieved.

    本发明公开了一种电梯门锁安全防困系统,其包括与电梯主机控制器串联的常规门锁回路、具有切换开关的与常规门锁回路并联设置的备用门锁回路,所述备用门锁回路与所述常规门锁回路通过切换开关接入门锁安全系统,同一个轿门或厅门的常规门锁开关与备用门锁开关的接触方向在空间上彼此垂直。常规门锁回路与备用门锁回路的触头接触方向设为相互垂直,当电梯运行时常规门锁回路产生故障时,备用门锁开关不会同时出现故障,从而迅速切换至备用门锁回路,恢复电梯运行至平层位置解救乘员离开电梯轿厢为止,无需长时间等待维护人员到达现场救援,实现快速安全救援。
