The invention provides a teaching simulant elevator training device. In the device, a vertically downward fixing guide rail is mounted in a transparent cabinet body of the device; a sliding groove is formed in the fixing guide rail; rotating shafts are arranged at the upper end and the lower end of the fixing guide rail; ratchet wheels are connected onto the rotating shafts; a stepping motor is arranged inside the cabinet body and used for driving the rotating shafts; a circle of transmission belt is arranged on the outer sides of the upper ratchet wheels and the lower ratchet wheels in a circulating manner; a movable platform capable of being horizontally lifted is further arranged inside the cabinet body, and is locked on the transmission belt through a locking mechanism; a sliding block is also fixed on the inner side of the movable platform, and is in sliding connection with the sliding groove in the fixing guide rail; a plurality of photoelectric sensors arrayed in one row at equal intervals from top to bottom are also arranged on the inner side of the cabinet body. The training device cooperates with the corresponding control training platform for joint use, students can observe the control running effect of the PLC, on the simulant elevator directly and vividly by the cabinet body, so that interest of students participating in the PLC training teaching is increased, and the teaching effect of the PLC courses is improved.
