Abstract

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.

Description

technical field [0001] The invention relates to the field of tension control winch hydraulic systems, in particular to a winch hydraulic system for controlling guide cables through stepless speed regulation and constant tension. Background technique [0002] In the complex and changeable marine environment, the hoisting equipment will be subjected to additional additional force due to external factors (such as the influence of wave fluctuations and ocean currents, etc.), which will make the hoisting equipment drift with the waves, and the stability of the hoisting equipment is poor, and more may be damaged or lost. [0003] In order to ensure the stability of the equipment, when the hoisting equipment is hoisting precision equipment (such as equipment carrying precision instruments or underwater manned submersibles), it is usually necessary to use fairlead ballast to assist hoisting. During the hoisting process of precision equipment, the tension on the fairlead cable needs...
