The invention relates to a walking landing leg system of a railway rescue crane, and belongs to the field of auxiliary facilities of cranes. According to the system, a landing leg locking mechanism is clamped on the upper surface of a longitudinal beam and moves longitudinally along the longitudinal beam; a supporting cylinder of the landing leg mechanism is fixedly connected with the landing leg locking mechanism, and moves relative to the longitudinal beam through the landing leg locking mechanism, and a landing leg body of the landing leg mechanism is in hinge connection with a crane body; two sets of double-shaft turning walking wheel stands are connected with the longitudinal beam through a bearing core plate, concentrated load of the landing legs of the crane is dispersely transmitted to railway tracks at two sides through four pairs of wheel pairs, not only are the problems of the overlarge concentrated load of the landing legs of the crane on the railway tracks and walking with load solved, but also the longitudinal movement along the longitudinal beam, the lifting movement along the direction vertical to the longitudinal beam and the rotating movement relative to the longitudinal beam, of the landing leg mechanism of the crane are realized, so that the crane is endowed with the performance of walking movement and rotating movement through the landing leg mechanism of the crane, and the applicability and the work efficiency of the railway rescue crane are comprehensively improved.
