Embodiment 1
[0038] A hydraulic system of a self-propelled steel rake grab dredger, including a hydraulic actuator, a hydraulic pump station, a hydraulic control system, hydraulic pipelines, and a hydraulic electric control system, characterized by:
[0039] (1) The hydraulic actuator includes four sets of positioning pile lifting devices, two trolley travel cylinders, one steel rake lifting winch, and four windlass winches;
[0040] (2) The configuration of the system power pump group is as follows:
[0041] Each lifting device is equipped with 2 sets of 22KW motor pumps in parallel to supply oil to the lifting cylinder, and the running speed of a single set is halved, that is, the two sets are emergency for each other, which improves the reliability of the system. There are 8 sets of motor pumps in the whole ship;
[0042] Two sets of 4KW motor-pump units are dispatched throughout the ship to supply oil to the pin oil cylinder. Depending on the actual working conditions, one or two sets ...

Embodiment 3
[0098] A hydraulic system of a self-propelled steel rake grab dredger, including a hydraulic actuator, a hydraulic pump station, a hydraulic control system, hydraulic pipelines, and a hydraulic electric control system, characterized by:
[0099] (1) The hydraulic actuator includes four sets of positioning pile lifting devices, two trolley travel cylinders, one steel rake lifting winch, and four windlass winches;
[0100] (2) The configuration of the system power pump group is as follows:
[0101] Each lifting device is equipped with 2 sets of 22KW motor pumps in parallel to supply oil to the lifting cylinder, and the running speed of a single set is halved, that is, the two sets are emergency for each other, which improves the reliability of the system. There are 8 sets of motor pumps in the whole ship;
[0102] Two sets of 4KW motor-pump units are dispatched throughout the ship to supply oil to the pin oil cylinder. Depending on the actual working conditions, one or two sets ...
