Abstract

The invention discloses a three-degree-of-freedom sliding groove type connector for connecting a transfer barge and a semi-submersible platform. The connector comprises a boss appendage arranged on the transfer barge and two channel appendages arranged on the semi-submersible platform, wherein the number of the channel appendages is two, and the boss appendage is inserted between the two channel appendages; vertically distributed sliding grooves are formed in the two channel appendages; the cross section of the sliding groove is trapezoidal; the two side faces of the boss appendage are each provided with a pin shaft hole, and a pin shaft is arranged in each pin shaft hole in a penetrating mode; a telescopic mechanism is arranged at the tail part of the pin shaft; the two pin shafts are respectively inserted into the sliding grooves; the central axes of the two pin shafts coincide with each other; and the two side faces of the boss appendage and the front end face, close to the semi-submersible platform, of the boss appendage are each provided with an arc-shaped face. Accurate butt joint, rapid connection and tight connection can be achieved, and the vertical degree of freedom, the rolling degree of freedom and the pitching degree of freedom between connecting interfaces can be released.

Description

technical field

[0001] The invention relates to the technical field of marine equipment, in particular to a three-degree-of-freedom chute connector for connecting a transfer barge to a semi-submersible platform. Background technique

[0002] The ultra-large floating platform is used as a transfer of marine equipment and materials and as an aviation island platform base. It can quickly deploy floating deployment berths in important sea areas of the national ocean strategy or international waters, serving the national ocean power strategy. The construction of ultra-large floating platforms is complicated in configuration and huge in size. The purpose of offshore connection is to solve the problems of engineering design and construction, offshore transportation, and engineering installation of ultra-large floating platforms with complex configurations.

[0003] In the "Floating Support Platform Engineering (Phase III)" special project of the high-tech ship scientific research p...
