Steel wire rope limiting device suitable for crawler crane

The utility model discloses a steel wire rope limiting device suitable for a crawler crane, and relates to the technical field of ocean engineering. Comprising supporting plates, a base is arranged between the supporting plates, the two ends of the base are fixedly welded to the supporting plates, L-shaped supporting plates are arranged on the base in a bilateral symmetry mode, transverse shaft mechanisms are arranged between the L-shaped supporting plates in an up-down mode, and a plurality of first bolt holes are evenly formed in vertical plates of the L-shaped supporting plates. Through the arrangement of the transverse shaft mechanism and the vertical shaft mechanism, the first rotating shaft rotates between the bearings, and the second rotating shaft upper shaft, the second rotating shaft middle shaft and the second rotating shaft lower shaft rotate with the supporting shaft as the axis. A steel wire rope is arranged in a rectangle defined by the two first rotating shafts, the four second rotating shaft
