The invention relates to the technical field of windlasses, and discloses a marine hydraulic windlass which comprises a reduction gearbox and a main shaft, a first fixing shaft is fixedly installed in the middle of the left surface of an inner cavity of the reduction gearbox, and the middle of the first fixing shaft is movably sleeved with a permanent magnet driven gear. The electromagnetic gear, the second tension spring, the sliding rail, the permanent magnet block and the fixing block are arranged on the main shaft, and the electromagnetic vertical worm, the first tension spring and the sliding rail are arranged on the second fixing shaft, so that the electromagnetic gear is controlled to be powered on and the electromagnetic vertical worm is controlled to be powered off when equipment is anchored, the magnetic pole of the electromagnetic gear is an N pole, and the magnetic pole of the electromagnetic vertical worm is an S pole; the electromagnetic gear is separated from the permanent magnet driven gear through magnetic repulsion force between the permanent magnet block and the electromagnetic gear and tension force of the second tension spring, meanwhile, the electromagnetic vertical worm is meshed with the turbine through magnetic attraction force between the permanent magnet block and the electromagnetic vertical worm, the transmission ratio is increased, then the torque during anchor weighing is increased, and the ship anchor can be easily pulled out of silt.
本发明涉及起锚机技术领域,且公开了一种船舶用液压起锚机,包括减速箱、主轴,所述减速箱内腔左表面的中部固定安装有第一固定轴,所述第一固定轴的中部活动套接有永磁从动齿轮。本发明通过主轴上设有电磁齿轮、第二拉簧、滑轨、永磁块和固定块,且第二固定轴上设有电磁竖状蜗杆、第一拉簧和滑轨,使设备在起锚时控制电磁齿轮得电和电磁竖状蜗杆断电,此时电磁齿轮的磁极为N极,电磁竖状蜗杆的磁极为S极,通过永磁块与电磁齿轮之间的磁斥力和第二拉簧的拉力使电磁齿轮与永磁从动齿轮分离,同时通过永磁块与电磁竖状蜗杆之间的磁吸力使电磁竖状蜗杆与涡轮啮合,增加了传动比,进而增大了起锚时的力矩,易于将船锚从泥沙中拉出。
