The invention discloses a winch towing cable tension measurement driving mechanism. The mechanism comprises a mounting base, a pin shaft type tension sensor, a tension measurement plate, a hydraulic motor, a winch speed reducer and a winding drum shaft, wherein a bearing is arranged between the mounting seat and the winding drum shaft; axial displacement of two ends of the bearing is limited by abearing inner retainer ring and a bearing outer retainer ring; sealing rings are arranged in the mounting seat and the bearing outer retainer ring; the hydraulic motor is directly in butt joint with the winch speed reducer; a winch speed reducer rotor is in bolted connection with the winding drum shaft; and a winch speed reducer stator is in bolted connection with the tension measurement plate; asupporting area of the pin shaft type tension sensor is positioned on mounting holes of a sensor seat and the mounting seat; and a bearing area is positioned on a stress hole of the tension measurement plate. The tension of the towing cable is calculated according to the tension measured by the pin shaft type sensor and structural geometrical parameters, the capability of monitoring the tension ofthe towing cable can be realized in real time under the conditions of rotation and braking of the winch speed reducer, and the winch towing cable tension measurement driving mechanism has the advantages of compact structure, stable measurement, high precision and the like.
