Single point mooring yoke support hinged joint structure with offshore bearing replacing function

Abstract

The invention discloses a single point mooring yoke support hinged joint structure with an offshore bearing replacing function. The structure comprises a nose cone body, an inner ring is arranged at the lower end of the nose cone body, the upper surface, the outer side face and the lower surface of the inner ring are each provided with an upper outer ring and a middle outer ring, the lower surfaces of the upper outer rings are in contact with the inner ring through an upper ring lining plate, the upper outer rings are fixedly connected with the middle outer rings through bolts, the inner surfaces of the middle outer rings are in step shapes, the vertical face of an inner step makes contact with the outer side face of the inner ring through a side lining plate, the horizontal plane of the inner step is connected with the lower surface of the inner ring through a lower ring lining plate, the middle outer rings are fixedly connected with lower outer rings through bolts, annular table grooves are formed in the centers of the lower outer rings, an auxiliary bearing pedestal is arranged on the center of the lower end of the nose cone body, a boss is arranged on the outer ring of an auxiliary bearing pedestal, the boss of the auxiliary bearing pedestal is in abut joint with the annular table grooves of the lower outer rings, and contact is achieved through auxiliary lining plates. Theproblem of offshore difficult replacing of a transverse shaking bearing of a yoke support hinged joint is solved.

Description

technical field [0001] The invention relates to the technical field of single-point mooring on offshore platforms, in particular to a single-point mooring yoke joint structure capable of replacing bearings at sea. Background technique [0002] The single-point mooring system can moor the ship in the sea area where it is operating, and has a vane effect, allowing the ship to rotate and swing around the single-point mooring. The yoke joint is the part that connects the mooring jib and the slewing tower in the single point mooring system. While transmitting the mooring force, the yoke joint has two rotational degrees of freedom, including controlling the mooring jib roll and The two pitching bearings are used to adapt to the rolling and pitching motion of the hull under various loads such as wind, waves, currents, and ice. [0003] Among them, the roll bearing of the yoke joint is used to release the roll degree of freedom of the mooring jib, and swings with the roll of the mo...
