The invention discloses a hydraulic control system of a crude oil outer conveying hose boom, and belongs to the field of hydraulic pressure. The hydraulic control system comprises two hydraulic oil cylinders, and comprises a speed control valve set, and the speed control valve set comprises a first two-position four-way electromagnetic valve, a second two-position four-way electromagnetic valve, atwo-way cartridge valve, a sequence valve and a first one-way valve; an oil inlet of the second two-position four-way electromagnetic valve communicates with an oil outlet of the first one-way valve,a first working oil port of the second two-position four-way electromagnetic valve communicates with an oil inlet of the first two-position four-way electromagnetic valve, a second working oil port of the second two-position four-way electromagnetic valve does not communicate, and an oil return port of the second two-position four-way electromagnetic valve communicates with a first oil port of the two-way cartridge valve; and a first oil port of the two-way cartridge valve communicates with an oil inlet of the first one-way valve, a second oil port of the two-way cartridge valve communicateswith the rod ends of the two hydraulic cylinders, and a control oil port of the two-way cartridge valve communicates with an oil inlet of a first two-position four-way solenoid valve. According to theinvention, the lifting time of the hose can be shortened.
Description
technical field [0001] The invention relates to the field of hydraulic pressure, in particular to a hydraulic control system for a crude oil transportation hose boom. Background technique [0002] Floating Production Storage and Offloading (English: Floating Production Storage and Offloading, abbreviation: FPSO) can carry out preliminary processing and storage of crude oil, and is called "offshore oil factory". The crude oil export system connects the head of the tanker to the tail of the FPSO through a mooring cable, and transports the crude oil stored in the FPSO to the tanker through a floating hose. [0003] The crude oil transportation system includes a drawworks with hoses stored there, jibs and piping devices. The jib is arranged in the direction in which the winch retracts and unwinds the hose, and is used to lift the hose and prevent the hose from touching the outside. The jib includes a straight rod, two L-shaped rods and two hydraulic cylinders. The first ends ...
