Embodiment Construction

[0029] like Figure 1-5 As shown, the whole structure of the large-scale flexible connecting bridge between floating bodies that can suppress movement in the present invention mainly includes a load-bearing beam connected by a main girder 6 and a telescopic beam 4 nested, a flexible folded leaf 2 with rollers, an equidistant displacement device 5, Axial movement damper 7, rotation damper 3. The structure and function of each component are as follows:

[0030] Main beam 6: It is the main load-bearing structure connecting the floating body 1. One end of the main beam 6 is hinged with the end of the floating body 1 through a ball joint 8, and the other end is nested and connected with the telescopic beam 4. The bottom of the main beam 6 is provided with a limit connecting rod 6.1. The flexible laminated leaves 2 are laid on the main beam 6 as the movement guide rail of the flexible laminated leaves 2 slider, and at the same time play the function of constraining the movement of...

Abstract

The invention discloses a flexible connecting bridge between large floating bodies capable of restraining motion. The flexible connecting bridge comprises a force bearing beam rotatably connected between floating bodies (1); a flexible folding blade (2) arranged above the force bearing beam; an equidistant displacement device (5) which is connected between the two floating bodies (1) and connected with rolling bodies (9) in an associated mode, wherein the blades are driven to move on a main beam (6) and a telescopic beam (4) at equal intervals to achieve bridge floor leveling; an axial motion damper (7) which is axially mounted between the main beam (6) and the telescopic beam (4); and rotary dampers (3) which are obliquely supported between the beams and the floating bodies (1) at the ends where the beams are located. The motion response between the floating bodies can be effectively improved, the working environment grade is improved, and compared with the current integral large floating body which is generally not higher than 5-grade sea conditions, the sea condition adaptation grade of open sea deployment can be improved to 6-grade or above after the floating bodies are adopted. And the flexible connecting bridge can also be used for flexible connection between medium-sized or conventional floating bodies.

Description

technical field [0001] The invention belongs to the technical field of marine engineering equipment, and in particular relates to a flexible connecting bridge device between large floating bodies for motion response suppression. Background technique [0002] Large or ultra-large offshore floating bodies are an important application direction in the field of military and civilian equipment such as offshore airports, offshore production and operation platforms, and offshore supply platforms in the future. Due to the limitation of operation requirements, it needs to be deployed at sea for a long time, and must have the ability to overcome the influence of wave motion and structural hydroelasticity. In terms of design scheme, the current connection between floating bodies generally adopts the technical scheme of multi-module connection. For example, the MOB concept platform in the United States and the offshore supply support base concept all adopt a multi-module combination me...
