Hydraulic system for rope guide device floating support

Abstract

The invention relates to a hydraulic system, in particular to a hydraulic system for rope guide device floating support and is particularly suitable for scientific investigation winches. The hydraulic system is characterized in that the hydraulic system comprises a supporting oil cylinder and a pressure relief valve; a rod cavity of the supporting oil cylinder is provided with a first oil port, and a rodless cavity of the supporting oil cylinder is provided with a second oil port; the pressure relief valve is provided with a first port, a second port and an oil drainage port; the first oil port of the supporting oil cylinder is connected with an oil return tank through a pipeline, and the second oil port of the supporting oil cylinder is connected with the first port of the pressure relief valve through a pipeline; and the oil drainage port of the pressure relief valve is connected with an oil drainage tank through a pipeline, and the second port of the pressure relief valve is connected with an oil supply tank through a pipeline. By the adoption of the hydraulic system, the installation mode of a rope guide device and a winch can be changed, unnecessary friction is avoided, and thus the service life of mooring ropes can be prolonged.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system for floating support of a cable guide device, and is especially suitable for scientific research winches. Background technique [0002] A winch is a light and small lifting device that uses a drum to wind a cable to lift or pull a heavy object, also known as a hoist. In order to facilitate the entry and exit of the cable, a cable guide device is generally provided on the winch. At present, the cable guides are all directly fixed on the winch, which makes it impossible to change the angle of the cable guides. However, in the actual use process, the rope inlet and outlet positions of the winch rope storage device will generally rise and change, so that the rope inlet and outlet positions are inconsistent with the height of the fixedly installed cable guide device, and the situation of inclining rope inlet and outlet occurs. This causes unnecessary friction between the cabl...

At present, the fairleads are all directly fixed on the winch, which makes it impossible to change the angle of the fairleads

However, in the actual use process, the rope inlet and outlet positions of the winch rope storage device will generally rise and change, so that the rope inlet and outlet positions are inconsistent with the height of the fixedly installed cable guide device, and the situation of inclining rope inlet and outlet occurs. Cause unnecessary friction between the cable and the fairlead mechanism, accelerate the wear rate of the cable, and shorten the service life of the cable
