Description
Technical field
The invention belongs to mooring cable field, more particularly to a kind of high intensity end change.
Background technology
With the quickening of global industrial shift paces, the manufacture part of ocean engineering has been transferred to Asia substantially at present
Country.But the pith such as the anchoring and control panel of extra large frock in, still provided by enterprise of American-European countries.Thus may be used
See, develop itself the deepwater mooring system system into Analysis of Nested Design and the importance of ability to provide the auxiliary items.
For a long time, ocean platform be Marine oil and gas resource exploitation main tool, with marine resources development gradually to
Abyss field is drive on boldly, and traditional jack up fixed platform is no longer applicable, and oil development business both domestic and external uses semi-submersible type one after another
Drilling platforms and Floating Production oil storage system（FPSO）Deng deep-sea oil resource toolkit.No matter which kind of instrument, will be long-term
Mooring is in specific marine site, and this just proposes higher, more demands to the deepwater mooring system system, to the need of the deepwater mooring system system
Problem is asked also to increase sharply.
At present, R4 level marine mooring chains are generally used on deep sea drilling platform, it has high intensity, obdurability, resistance to
Corrosion and antifatigue technical characteristic, the wherein change of R4 levels are the annexes on seafari mooring platform chain, common change its
Bearing capacity is small, it is impossible to be used in the connection of mooring platform chain cochain bar, is provided according to classification society of American-European countries, ocean marine anchor chain
Level Four standard must be reached with seafari platform mooring cable swivel shackle, because four-grade mooring chain material can not be welded
Connect, so existing domestic common change may not apply to seafari mooring cable.
End change on oil platform possesses high intensity, the technical characteristic of obdurability, and the end after heat treatment turns
Ring, according to requirement is manufactured, its external form and internal soundness should meet the related request of classification society.In the mooring gear of oil platform
In, it may be desirable to a kind of shackle can be while two chain groups be connected, it can be ensured that flexible rotating, avoids that hinge phenomenon occurs, together
When be also required to be easily installed, be easy to the replacing of chain group.
The content of the invention
The present invention provides a kind of change of high intensity end, solves above technical problem.
The object of the present invention is achieved like this：A kind of change of high intensity end, comprising change body, end key, its
It is characterised by：Described end key upper end is locked in change body through change body by rotating nut riveting, described
End key be arranged to Y shape, the Y shape opening of described end key is provided with lateral pin and closed through end key lower end composition
Cyclization, described lateral pin right side are provided with nut check, and being provided with alignment pin on the right side of described nut passes through lateral pin.
Described change body includes body U-loop and body circular rings, and described body U-loop hangs down with body circular rings
Directly, the section of described body U-loop is provided in round, and splayed circular hole is provided with described body circular rings.
The Y shape of described end key is justified comprising end thread, terminal linkage, the circular arc of end first and end second
Arc；By cylinder transition between described terminal linkage and the circular arc of end first, described terminal linkage is arranged to and this
The splayed that the splayed circular hole of body circular rings matches, the described circular arc of end first and the circular arc of end second are tangent, described
End second circular arc be provided centrally with pin-and-hole.
Riveting chamfering is provided with the top of described rotating nut.
The present invention compared with prior art, has beneficial at effect：End key upper end is through change body by rotating spiral shell
Mother's riveting is locked in change body, improves bonding strength；End key is connected with the junction of change body using splayed,
Increase perishable section of thickness, improve service life.
