The invention discloses a steel rail walking device and a railway turnout paving machine comprising the same. The steel rail walking device comprises a frame, a heart plate, oil cylinders, lifting connecting rod mechanisms, steel rail wheels, a side bearing and wheel mounting frames, wherein the steel rail wheels are installed on the wheel installing frames, the wheel installing frames are hingedto the frame, and the frame is hinged to one ends of the lifting connecting rod mechanisms at the same time; the other ends of the lifting connecting rod mechanisms are connected with the oil cylinders, the telescopic driving of the oil cylinders is utilized to drive the lifting connecting rod mechanisms to move, and then the lifting connecting rod mechanisms are used for driving the steel rail wheels to realize winding and unwinding operation so as to avoid the interference of the steel rail wheels to the turnout during turnout hoisting operation of the railway turnout paving machine; and theheart plate and the side bearing are arranged on the frame, and the steel rail walking device is connected with a sleeper beam of the railway turnout paving machine through the heart plate and the side bearing. According to the steel rail walking device, the technical problems that the existing railway turnout paving machine is low in walking speed, large in running limitation on a railway ballast and poor in maneuverability in a long-distance special field can be solved.
