Winding mechanism with tension control function and trawling apparatus |
摘要 |
To provide a winding mechanism and a trawling apparatus capable of eliminating an excessive tension or slack generated in a wire wound around a drum and keeping the tension or wire length of the wire constant. A winding mechanism with tension control function includes a reversibly rotatable liquid-pressure motor rotating a drum having a wire wound therearound, a liquid-pressure pump coupled directly with the liquid-pressure motor and supplying hydraulic oil, and an electric motor rotating to drive the liquid-pressure pump. The winding mechanism further includes a control unit controlling a torque of the electric motor based on a variation in load current of the electric motor and winding off or winding up the wire to keep the tension of the wire at a set value.
