Advantageous effects
The scheme has simple structure and convenient installation and maintenance, and the invention adopts simple and reliable structures such as the telescopic oil cylinder, the rotating device, the sliding structure and the like, and adopts reasonable matching forms of all mechanisms to complete the motion compensation of three degrees of freedom of rolling, pitching and heaving between the crane installation plane and the ship body. The scheme can compensate the motion of the crane with three degrees of freedom when marine equipment (such as ships and marine platforms) generates rolling, pitching and heaving motions due to severe sea conditions, and can limit the displacement or rotation of the crane with three degrees of freedom in horizontal transverse direction (such as ship width direction), horizontal longitudinal direction (such as ship length direction) and horizontal plane (such as horizontal plane parallel to a ship deck), so as to ensure that the crane is always in a horizontal stable state in severe sea conditions.
