Corridor elevator

The invention discloses a corridor elevator. The corridor elevator is characterized by comprising an elevator support, a rail car device and a control system; the elevator support is arranged on stairs; the rail car device is used for vertically moving on the elevator support in a reciprocating mode; the control system is used for controlling the corridor elevator to work. The axis of a first steel wire grooved pulley and the axis of a second steel wire grooved pulley are perpendicular to an upper rail, a lower rail and a traction steel wire which is arranged between the rail car device and the second steel wire grooved pulley are arranged parallel to each other, and accordingly the traction steel wire can walk along the direction of the upper rail and the stability of the traction process is improved. The traction steel wire which winds a steel wire cylinder swings in the direction of the axis of the steel wire cylinder when the traction steel wire winds in or out of the steel wire cylinder, the axis of the steel wire cylinder is perpendicular to the axis of the first steel wire grooved pulley, and accordingly the swing effect of the traction steel wire can be avoided to enable the traction steel wire to smoothly enter a groove of the first steel wire grooved pulley and the smoothness of the movement of the traction steel wire is improved.
