Steel wire rope locking device for winch

The invention relates to a steel wire rope locking device for a winch. The steel wire rope locking device is characterized by comprising a support; the support comprises a rectangular baseplate; two L-shaped support plates are arranged on the two relative edges of the baseplate; vertical plate faces of the support plates are parallel and are arranged relatively, and transverse lower edges of the support plates are integrally connected with the baseplate; a rotating shaft is arranged between the vertical parts, far away from the transverse parts, of the two support plates; the two ends of the rotating shaft is movably matched with the corresponding support plates; two support arms are arranged on the baseplate, the same ends of the two support arms are respectively connected to the two ends of the rotating shaft; a middle shaft is arranged between the two support arms; a pressure roller is arranged between the outer ends of the two support arms; springs are connected between the two ends of the middle shaft and the upper parts of the corresponding support plates of the middle shaft; the two ends of a roll shaft of the pressure roller are rotatably matched with the outer ends of the corresponding support plates of the roll shaft. By adopting the device, a steel wire rope of the winch can be effectively compressed to prevent loose, thus avoiding damage to the winch or the rope due to instant falling off of a load.
