The invention discloses a combined winch hydraulic system of an ultra-large pile driving barge. The combined winch hydraulic system of the ultra-large pile driving barge comprises a barge moving winch hydraulic system, a hoisting winch hydraulic system and a PLC electric control system, wherein oil inlets of a plurality of barge moving oil pump control valves in the barge moving winch hydraulic system are correspondingly connected with oil outlets of a plurality of barge moving winch oil supply pumps, a high-pressure oil supply header pipe is connected with right oil outlets of the barge moving oil pump control valves, a low-pressure oil supply header pipe is connected with left outlets of the barge moving oil pump control valves, and high-pressure oil inlets and low-pressure oil inlets of barge moving oil taking control valves correspondingly communicate with the high-pressure oil supply header pipe and the low-pressure oil supply header pipe; middle path inlets of a plurality of lifting oil pump control valves in the lifting winch hydraulic system are correspondingly connected with oil outlets of a plurality of lifting winch oil supply pumps, and left and right inlets of the multiple lifting oil pump control valves are correspondingly connected with the high-pressure header pipe and the low-pressure oil supply header pipe. According to the combined winch hydraulic system of the ultra-large pile driving barge, the matching adaptability and efficiency of the pump station power and the winch load are improved, the real-time energy consumption is reduced, and the equipment configuration redundancy is high.
