Problems solved by technology

[0004] At present, the connection of domestic offshore structures only relies on mooring cables for soft connection. This connection method is only suitable for port operations or under low sea conditions. There is no technical solution to solve the docking problem between ships and floating structures under high sea conditions.

Embodiment Construction

[0023] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, a three-degree-of-freedom chute connector for connecting a transfer barge to a semi-submersible platform, which includes a boss attachment 20 located on the transfer barge 10 and a channel attachment located on the semi-submersible platform 11 Body 30.

[0025] There are two channel attachments 30 , and the boss attachment 20 is inserted between the two channel attachments 30 .

[0026] The two channel appendages 30 are provided with vertically distributed sliding slots 31 . The cross section of the chute 31 is trapezoidal. The width of the bottom of the chute is smaller than the width of the mouth of the chute.

[0027] Two side surfaces of the boss attachment 20 are respectively provided with a pin shaft hole 21 , an...

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...
