According to the protection device for accidental movement of the lift car, a first sensor is fixedly connected to the middle of the top of a lift door, a signal transmission road section is fixedly connected to the top of the first sensor, and a central control system is fixedly connected to one side of the signal transmission road section; an independent control system is fixedly connected into the central control system, a main body control system is fixedly connected to one side of the independent control system, a signal converter is fixedly connected into the independent control system, and a second sensor is fixedly connected to the middle of the bottom of the elevator door. The first inductor and the second inductor are used for inducting closing of an elevator door, the inductors are connected into the independent control system, the independent control system is based on the main body control system and is not shared, and when the main body control system causes accidental movement of the elevator car, the independent control system is not affected, and the safety of the elevator car is guaranteed. The independent control system mainly controls the limiting mechanism and the protection mechanism, and the main body control system controls operation of the elevator.
本发明公开了一种轿厢意外移动的保护装置,包括电梯门的顶部中间部位固定连接有第一感应器,第一感应器的顶部固定连接有信号传输路段,信号传输路段的一侧固定连接有中央控制系统,中央控制系统的内部固定连接有独立控制系统,独立控制系统的一侧固定连接有主体控制系统,独立控制系统的内部固定连接有信号转换器,电梯门的底部中间部位固定连接有第二感应器,第一感应器和第二感应器用来感应电梯门的关闭,且感应器接入控制在独立控制系统,独立控制系统为基于主体控制系统的单独控制系统,不进行共享,当主体控制系统造成轿厢意外移动时,独立控制系统不受到影响,独立控制系统主要控制限位机构与防护机构,主体控制系统的控制为电梯的运行。
