Description
Technical field
The invention belongs to ocean engineering field, and in particular to a kind of six degree of freedom flexible connector.
Background technology
Very Large Floating Structure is the great high-end ocean work for basing oneself upon the maintenance of national marine rights and interests and deep-ocean resource exploitation
Journey is equipped.It can be used as off-lying sea fast transportation transport hub, large-scale far-reaching sea exploitation operating platform, ocean goods and materials storage relay station
And synthesis military platform of Marine Mobile fast reaction etc..Due to the enormous size of Very Large Floating Structure, from construction, fortune
Defeated and regular maintenance etc. considers that it is doomed to use modularization assemble structure.Therefore connector turns into modular construction
Critical component, conventional people often lead to stress concentration, structure is difficult to using rigidity or the semi-rigid connectors such as welding, be hinged
Bear.
Chinese invention patent " very large floating structures intermodule connector and connection method（Application number：
201210496392.6）", " be applied to very large floating structures intermodule connector and connection method（Application number：
201410199638.2）", a kind of " dynamic adjustable negative pressure vacuum cap type connector of ocean floating body（Application number：
201610161973.2）" etc. for ultra-large type offshore floating type works modularization connect, it is proposed that if flexible connector fill
Put, and realize the function of Fast Installation dismounting, but it is related to the executing agency of complexity such as hydraulic jack, electromagnetism and inhaled mostly
Disk, vacuum cup etc., for the marine evil slightly environment residing for Very Large Floating Structure, its safety and reliability is difficult to
Ensure.Moreover, the problem of connector generally existing shear strength of prior art is inadequate.
In summary, the connector between the Very Large Floating Structure of prior art and the structure of connection are primarily present
Bonding strength is inadequate, and quick-assembling difficult to realize and the demand freed.
The content of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of anti-shear ability is strong, can effectively reduce structural stress, structure
Simple and compact, the six degree of freedom flexible connector for being convenient for changing maintenance.
The technical scheme of the present invention that solves the problems, such as is：A kind of six degree of freedom flexible connector, including deck and pedestal, it is described
Deck is rotary structure, and deck includes cross section for the body of shape of chinese word Ji, the Access Division for being fixedly connected on bodies top, setting
In the column that body half is opened wide in cavity, the Access Division is provided with neck；
The pedestal is the revolving body that cross section is shape of chinese word Ji, and half that deck body is inserted at the top of pedestal is opened wide in cavity, column
At the top of through pedestal and stretch into half unlimited cavity of pedestal；

Rigid backing plate can improve the rigidity of each elastic polymer material packing ring, increase the bonding strength of connector.
To avoid the connector, deck collides with shell in the course of the work, the side wall of the deck body with it is outer
Gap is left between the through hole edge of shell.
Further, the half of the first elastic polymer material packing ring and deck body is opened wide between cavity top inwall
Leave gap；
Sulfided between first elastic polymer material packing ring and deck body, pedestal and rigid backing plate.
Gap is left between the 3rd elastic polymer material packing ring and outer casing inner wall；
Vulcanization is one between 3rd elastic polymer material packing ring and deck this lateral edge, pedestal lateral edges and rigid backing plate
Rise.
Between the 4th elastic polymer material packing ring and outer casing inner wall and with being left between deck this body sidewall
Gap；
Vulcanization exists at the top of 4th elastic polymer material packing ring and deck this lateral edge, shell inner cavity and between rigid backing plate
Together.
Sulfided between second elastic polymer material packing ring and pedestal and column.
In such scheme, the purpose in gap is stayed to be to provide headspace for the deformation of each elastic polymer material packing ring.
Vulcanization can prevent connector contact surface in different stresses from separating.Sulfide site is synchronized with the movement, and on the one hand prevents
Gap is produced in cyclic loading and is worn, and more big load can be born by being on the one hand synchronized with the movement.
Preferably, the body of the deck is integrally formed with Access Division；The snap-latch surface of the neck is inclined-plane.Work as snap-latch surface
For inclined-plane when, self-lock ability is stronger.
Preferably, the centre of gyration line three weight of the centre of gyration line of the deck, the centre of gyration line of pedestal, shell
Close.
Preferably, the cover top portion is provided with cyclic reinforcing rib, and radial reinforcement is provided with along cover top portion and side wall.
The present invention six degree of freedom flexible connector it is simple and compact for structure, load can be effectively reduced, make its occur tension and compression,
Load, especially its shearing strength are transmitted during the deformation such as bending by elastic polymer material to greatly promote, it is ensured that ultra-large type is floated
Body safe operation.Moreover, the connector is modular construction, maintenance is convenient for changing.
The floating platform attachment structure coordinated with the six degree of freedom flexible connector of the present invention, can quickly be connected and disconnected from,
Realize six degree of freedom elastic restraint.
