The invention discloses a safety maintenance device for passenger conveying equipment. The safety maintenance device comprises a plurality of maintenance sockets, a mobile maintenance device, a first detection loop, a second detection loop and a control device, the control device is provided with a maintenance state verification module, and the maintenance state verification module comprises a main control unit, a signal input unit A and a signal input unit B; each maintenance socket is provided with a first pair of pins which are connected in series to the first detection loop, and a second pair of pins which are connected in parallel to each other to be connected to the second detection loop; when the signal of the first detection loop is the same as the signal of the second detection loop, the main control unit judges that the safety maintenance device is in an abnormal state; and when the signal of the first detection loop indicates that the first detection loop is disconnected and the signal of the second detection loop indicates that the second detection loop is connected, the main control unit judges that the safety maintenance device is normal and enables the passenger conveying equipment to enter a maintenance state.
本发明公开了一种乘客输送设备的安全检修装置,包括多个检修插座、移动检修装置、第一检测回路、第二检测回路和控制装置;控制装置具有检修状态校验模块,检修状态校验模块包括主控单元、信号输入单元A和信号输入单元B;每个检修插座都具有第一对针脚串联接入第一检测回路,以及第二对针脚相互并联后接入第二检测回路;当第一检测回路的信号与第二检测回路的信号相同时,主控单元判断安全检修装置处于异常状态;当第一检测回路的信号表示第一检测回路断开,且第二检测回路的信号表示第二检测回路导通时,主控单元判断安全检修装置正常并使乘客输送设备进入检修状态。
