Study on Automatic Rope Arrangement for Large Capacity Winch

The rope arranging action of a large-scale winch is often disordered,which can cause rope damaged seriously and accidents of car runaway due to rope breaking,even results in heavy human injuries.Aimed at this situation,hydraulic speed-governing technology and PLC control technique are applied to the auto-control course of the rope arrangement of the winch,in order to realize signals gathered and monitored on real-time for the rotation velocity of the winch,the mov- ing direction and the displacement of the rope-arranging hydro-cylinder.Additionally,stepless speed regulation of the rope-arranging system is realized by regulating the frequency of explosion- proof converter,so that the purpose of tracking working condition of the winch dynamically and auto-controlling the rope-arranging process is achieved.
