The invention discloses an elevator accidental movement prevention protection device and an elevator, and the elevator accidental movement prevention protection device comprises a plurality of first relays which are connected in series and then connected to the two ends of a door lock loop of the elevator; the fault detection unit is configured to perform fault detection on each first relay and output a door lock bypass enable instruction under the condition that all the first relays work normally and a door lock bypass enable signal is received; each control unit is connected with the fault detection unit and suitable for controlling one first relay, and each control unit is configured to control the corresponding first relay when at least one of the first position sensor and the second position sensor detects that the elevator car moves or does not receive a door lock bypass enabling instruction. And controlling the corresponding first relay to be switched off so as to control the elevator car to stop moving. The accidental movement prevention protection device for the elevator adopts a common relay, so that the cost is lower.

    本发明公开了一种电梯防意外移动保护装置及电梯,其中,电梯防意外移动保护装置包括:多个第一继电器,多个第一继电器串联后,并连接到电梯的门锁回路的两端;故障检测单元,故障检测单元被配置为对每个第一继电器进行故障检测,并在所有第一继电器工作正常、且接收到门锁旁路使能信号的情况下,输出门锁旁路使能指令;多个控制单元,每个控制单元分别与故障检测单元相连,且适于控制一个第一继电器,每个控制单元被配置为在第一位置传感器和第二位置传感器中至少一个检测到电梯轿厢发生移动、或未接收到门锁旁路使能指令的情况下,控制相应第一继电器断开,以控制电梯轿厢停止运动。该电梯防意外移动保护装置使用普通继电器,所以成本较低。
