Abstract

The invention discloses a hydraulic power control system for a hydraulic plug type lifting system and belongs to the field of ocean engineering. The hydraulic power control system comprises a hydraulic drive assembly, a first unloading loop, a second unloading loop and a third unloading loop. The hydraulic drive assembly comprises a first hydraulic pump, a second hydraulic pump, a third hydraulic pump and a drive device which provides power for the first hydraulic pump, the second hydraulic pump and the third hydraulic pump. The first unloading loop comprises a first pilot overflow valve and a first two-position two-way electromagnetic valve. The second unloading loop comprises a second pilot overflow valve and a second two-position two-way electromagnetic valve. The third unloading loop comprises a third pilot overflow valve and a third two-position two-way electromagnetic valve. When the hydraulic power control system is used for lifting pile legs, the first hydraulic pump and the second hydraulic pump provide oil for a lifting oil cylinder, the oil supplied to the lifting oil cylinder is increased, the telescoping speed of the lifting oil cylinder is increased, and then the lifting speed of the pile legs is increased.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a hydraulic power control system of a hydraulic bolt type lifting system. Background technique [0002] The jack-up offshore platform mainly includes multiple legs, lifting mechanism and platform main body. The lifting mechanism is the key core equipment of the jack-up offshore platform. The lifting mechanism is installed at the well of the pile legs, and the lifting mechanism is driven by the hydraulic power control system. Thereby, the relative movement between the main body of the platform and the legs is realized. [0003] The hydraulic bolt-type lifting system realizes the relative movement between the platform body and the legs through the cooperation of the lifting cylinder and the bolt cylinder. The hydraulic power control system of the existing hydraulic bolt-type lifting mechanism includes two hydraulic pumps, one of which is used to drive the bolt cylinder, another h...
