[0002] A hydraulic winch is a device that uses a hydraulic system to provide power. Its working principle is to convert pressure into mechanical energy through a hydraulic oil circuit, thereby driving the winch to rotate. When multiple hydraulic winches need to work at the same time, the oil circuits can be connected to achieve the coordinated work of multiple winches, improve work efficiency and rescue capabilities, and use the flow and pressure transmission of hydraulic oil to achieve centralized control and management of multiple winches. In practical applications, the technology of connecting multiple hydraulic winches to oil circuits is widely used in vehicle rescue, engineering construction, outdoor adventures and other fields, especially in occasions that require a lot of traction or require multiple winches to work together. The application of this technology is particularly important. The linkage between multiple winches must first be solved by how to supply oil to multiple winches at the same time without affecting each other. Summary of the invention

[0003] The problem to be solved by the present invention is how to supply oil to multiple winches simultaneously by linkage between the winches.

[0004] To achieve the above object, the technical solution of the present invention is: a method for supplying oil to a linkage system of multiple winches, which is used to supply oil to a linkage system of multiple winches, wherein the linkage system of the winches comprises: a winch control panel and a winch, wherein the winch control panel is connected to the winch, wherein a reversing valve and a pressure compensating valve are arranged in the winch control panel, wherein one end of the reversing valve is connected to the output end of the pressure compensating valve, and the other end of the reversing valve is connected to the input end of the pressure compensating valve and the winch; wherein a bidirectional hydraulic motor is arranged in the winch, and both ends of the bidirectional hydraulic motor are connected to the reversing valve; The specific steps include: S1, push the reversing valve in the winch console in one direction, and the hydraulic oil is delivered to the corresponding reversing valve; S2, the hydraulic oil flows to the pressure compensation valve through the reversing valve, and part of the hydraulic oil flows back to the reversing valve through the pressure compensation valve; S3, the hydraulic oil flowing back to the reversing valve flows to the bidirectional hydraulic motor in the winch; S4. Hydraulic oil flows back from the bidirectional hydraulic motor in the winch to the reversing valve.

[0005] This solution connects the capstan to the capstan operating console. An oil reversing valve is arranged in the capstan operating console. When the operator pushes the reversing valve, the hydraulic oil flows through the reversing valve and then flows into the bidirectional hydraulic motor in the capstan, driving the motor to rotate. When multiple capstans are linked, it is only necessary to push the reversing valve in the capstan operating console connected to the corresponding capstan, so as to accurately control each capstan.
