The invention discloses a winch hydraulic system controlling a guide rope through stepless speed regulating constant tension, and relates to the field of tension controlled winch hydraulic systems. The system comprises a fuel tank, a motor, a volume adjustable hydraulic pump, a one-way valve, a high-pressure overflow valve, a backpressure overflow valve, a motor operating valve bank, a winch motor, a brake oil cylinder, a plate-type overflow valve, a proportional overflow valve, a first threaded cartridge shuttle valve, a second threaded cartridge shuttle valve, a two-position two-way normally-closed ball valve, and a two-position three-way electromagnetic ball valve. The system can realize stepless speed regulation and constant tension control requirement of a guide cable winch, and can solve problems of power loss caused by high-pressure overflow in a conventional hydraulic winch constant tension control system, so as to save energy resources and improve efficiency of a hydraulic system. The system is designed by using an integrated valve block, and the design reduces volume space the system occupies, and reduces the number of system pipelines, and reduces failure rate. The system is convenient to install and maintain, and can realize batch and standardized production.
