Device for preventing steel wire rope reel of winch from being separated from groove

The utility model relates to the technical field of winches, in particular to a device for preventing a steel wire rope reel of a winch from disengaging from a groove, and solves the problem that a steel wire rope of the winch disengages from the groove and is disordered. A device for preventing a steel wire rope reel of a winch from disengaging from a groove comprises a base and two installation supporting arms. The base is fixed to a winch body through bolts. The bottoms of the two installation supporting arms are installed at the two ends of the base correspondingly. The tops of the two installation supporting arms are jointly connected with a carrier roller shaft, and the carrier roller shaft is rotationally sleeved with an anti-disengaging carrier roller. The anti-disengaging carrier roller abuts against a steel wire rope on a steel wire rope reel of the winch. The anti-disengaging carrier roller is additionally arranged beside the steel wire rope reel of the winch, so that the anti-disengaging carrier r
