Embodiment Construction

[0028] Such as Figure 1 to Figure 6 As shown, the flexible connector between modules of the ultra-large offshore floating platform disclosed in this embodiment includes a sliding column 1, a sliding sleeve 2, a rubber sleeve 3, a support 4, a spring steel plate 5, a slider 6, and a connecting shaft 7. The fixed seat 8 and the sliding sleeve block 9 are especially suitable for the docking of the platform module as an inner hollow square body.

[0029] In this embodiment, the sliding column 1 is a solid square column, the sliding sleeve 2 is a matching square tube, and the rubber sleeve 3 is elastically deformed when it is placed outside the sliding sleeve 2, so that the inner wall of the rubber sleeve 3 and the outer wall of the sliding sleeve 2 are in close contact. together, and the inner and outer walls of the rubber sleeve 3 are vulcanized. The rear end of the strut 1 has a threaded hole for connecting the support. The sliding column in other embodiments can also adopt t...

Abstract

The invention discloses a flexible connector arranged between ultra-large offshore floating platform modules and a butt joint method. The flexible connector comprises a slide column, a supporting seat, spring steel plates, slide blocks and a fixing seat; the front end of the slide column is provided with a hinge head, the supporting seat is connected to the rear end of the slide column, the springsteel plates are vertically connected to the supporting seat in pairs, and the slide blocks are connected to the two ends of the spring steel plates; the outer wall of the slide column is sleeved with a slide sleeve, the slide sleeve is closely sleeved with a rubber sleeve, and the rubber sleeve is embedded in a through hole formed in the fixing seat; the flexible connector is installed in an inner cavity of the platform module through the fixing seat, and the slide blocks make contact with the top surface and the bottom surface of the inner cavity of the platform module; the adjacent platform modules are connected through a hinge joint and a pin shaft of the flexible connector, and the slide column drives the slide blocks to move when moves along the slide sleeve. When transverse or vertical shearing force is applied to the hinge joint, the rubber sleeve is extruded to be deformed, and the transverse rigidity and the vertical rigidity of the connector are ensured. When the hinge joint is stretched or compressed, small rigidity in the longitudinal direction is achieved through the spring steel plates, and the stability of a floating body is ensured while the load of the connectoris decreased.

Description

technical field [0001] The invention belongs to the field of marine engineering, in particular to a flexible connector and a docking method between modules of an ultra-large offshore floating platform. Background technique [0002] The connector between the modules of the ultra-large floating platform is one of the important technical links in the design process of the ultra-large floating platform. Due to the huge size of the platform and the complex wave environment at sea, the loads on the connectors between the modules are very high. Huge, which brings great challenges to the structural design of the connector. [0003] For multi-degree-of-freedom flexible connectors, different stiffnesses in different directions have different effects on the system. A connector with a small vertical stiffness and a large horizontal and vertical stiffness design can greatly improve system performance. But there is no such connector with better performance at present. Contents of the i...
