Abstract

The invention discloses a hydraulic control system of a large cable winch, and belongs to the field of hydraulic systems. The hydraulic control system of the large cable winch comprises a hydraulic pump, a first reversing valve, a constant difference pressure-reducing valve, a two-way plug-in valve, a first throttling valve and a single-ball shuttle valve, wherein an oil outlet of the hydraulic pump separately communicates with an oil inlet of the constant difference pressure-reducing valve, a port B of the two-way plug-in valve and an oil inlet of the first throttling valve; an oil outlet ofthe first throttling valve communicates with a port X of the two-way plug-in valve; a port A of the two-way plug-in valve communicates with a port P of the first reversing valve; an port A of the first reversing valve communicates with a port A of a cable arranging motor; a port B of the first reversing valve communicates with a port B of the cable arranging motor; a port T of the first reversingvalve communicates with an oil tank; and an oil outlet of the constant difference pressure-reducing valve communicates with an oil inlet P port of the single-ball shuttle valve. The hydraulic controlsystem does not bear fluctuation influences of flow and load.

Description

Technical field [0001] The invention relates to the field of hydraulic systems, in particular to a hydraulic control system of a large cable winch. Background technique [0002] Large cable winches are used in crude oil transportation systems for oil transportation operations. [0003] There is a hydraulic control system for a large cable winch, which includes a reversing valve, an overflow valve, a motor and a hydraulic pump. The A and B ports of the reversing valve are respectively connected with the two working oils of the cable discharge motor of the large cable winch. The hydraulic pump is driven by the motor. The oil outlet of the hydraulic pump is connected to the oil inlet of the overflow valve and the P port of the reversing valve. The oil outlet of the overflow valve and the T port of the reversing valve are connected to the oil tank. . [0004] In the process of implementing the present invention, the inventor found that the prior art has at least the following problems:...
