The device is composed of a sliding rail, a chain, chain wheels, sliding wheels, a motor, a seat and a connection rod part. The chain, the chain wheels, the sliding wheels, the motor, the seat and the connection rod part are arranged on the sliding rail. As is shown in the figure, the sliding rail is arranged on the lower portion of an upper stair, the chain is arranged on one side of the sliding rail, sliding wheel sets slide in the sliding rail, the seat is suspended below one sliding rail set, and the motor and the chain wheels are suspended below the other three sliding rail sets. A user sits on the seat, the motor drives the chain wheels to rotate, the chain wheels move along the chain and drive the sliding wheel sets to slide in the rail and the seat to advance along the sliding rail simultaneously, and accordingly the function of going upstairs and downstairs is achieved.
