Big chain link.Because the structure of anchor cable is different, it is necessary to be attached using different connection members, structure very complicated, applicable model
Enclose narrow, production cost is high, simultaneously as fault of construction, causing the moment of torsion of anchor cable can not effectively be discharged, and be shortened
The service life of anchor cable.
The content of the invention
To solve problems of the prior art, anchor cable moment of torsion can be effectively discharged the invention provides a kind of
Mooring swivel.
The purpose of the present invention is implemented by the following technical programs：
A kind of mooring swivel, including：
Suspension ring and installation through-hole are provided with cyclic adapting piece, the cyclic adapting piece；
Fittings body, the fittings body includes connection end and cavity end, and the connection end plugs into the installation through-hole and extend out to
The installation through-hole opposite side, the cavity end is provided with cavity,
Fixation kit, the fixation kit is arranged on one end that the fittings body inserts the installation through-hole, it is ensured that the ring-type
Connector is connected with the fittings body.
Further, the fixation kit includes nut, and the nut is set in the connection end, and with the connection end
Threaded connection.
Further, the nut is welded to connect with the connection end.
Further, in addition to screw, the nut is fixedly connected by the screw with the connection end.
Further, the screw is 4, is uniformly arranged on the nut outer wall circumference.
Further, the cavity is tapered into along the cross-sectional area away from the connection extreme direction.
Further, the cavity is conical cavity.
Further, the installation through-hole is circular hole, and the connection end is cylinder, and the installation through-hole internal diameter is more than described
Connection end external diameter.
Further, the shackle of the suspension ring and anchor chain coordinates.
Further, the shackle is Kenter shackle.
The beneficial effects of the invention are as follows：
Mooring swivel disclosed in this invention, rationally, cyclic adapting piece connects shackle or other companies of anchor chain to scientific structure design
Fitting, the other end is directly integrated with anchor cable casting, it is no longer necessary to the part such as enlarged link, common link, end open link, anchoring
System architecture is simpler, while the moment of torsion of anchor cable is released by multi-functional change, extends the service life of anchor cable.
This change integrates change, Casting Joint, end open link, enlarged link, the function of joining shackle, with simple in construction, suitable
With scope is wide, reliability is high, flexible rotation, long lifespan the advantages of.This change could be applicable to the standby anchoring system of other extra large frocks
System.

Embodiment
With reference to specific embodiment, specific embodiments of the present invention is described in detail.
As Figure 1-3, the invention discloses a kind of mooring swivel, including：Cyclic adapting piece 100 and fittings body 200, ring
Shape connector 100 is rotated with fittings body 200 and is connected.
Suspension ring 110 and erecting bed 120 are provided with specific cyclic adapting piece 100, erecting bed 120 is with installation through-hole
121 round table-like structure, the upper and lower surface of 110 right angle setting platform of suspension ring 120 is set, and the one of suspension ring 110 and erecting bed 120 into
Type.The concrete shapes of suspension ring 110 and size are according to the Kenter shackle on its anchor chain to be attached or other connectors
Size carries out specific design, in the present case without limiting.
Fittings body 200 includes connection end 210 and cavity end 220, and the profile of connection end 210 is cylindric, and its external diameter is less than etc.
In the internal diameter of installation through-hole 121, it is ensured that leave certain gap between connection end 210 and installation through-hole 121, make fittings body 200
Connection end 210 and suspension ring 110 can be relatively rotated, and discharge the moment of torsion of anchor cable.And the height of connection end 210 is more than erecting bed
120 thickness
Cavity end 220 is integrally formed with connection end 210, and the concrete shape of cavity end 220 is set according to specific needs, at this
In embodiment, the outside of cavity end 220 inside cavity end 220, is provided with cavity 221 in the circular cone stage body that section is inverted trapezoidal,
Steel wire for accommodating castable and anchor cable, connects as one anchor cable and fittings body 200 after casting material solidification, to ensure casting
Effect, the shape that cavity 221 is set to taper into along the cross-sectional area away from the direction of connection end 210, in this implementation
Example in, cavity 221 be shaped to it is similar to shape cavity end 220 outside, be similarly section for inverted trapezoidal the frustum of a cone
Shape, inside connection end 210, is again provided with cavity 211, cavity 211 is cylindrical, itself and the cavity inside cavity end 221
It is identical, and its internal diameter is identical with the top internal diameter of the cavity 221 inside cavity end 220.
Connection end 210 is plugged in installation through-hole 121, and its end extend out to the opposite side of installation through-hole 121, as shown in figure 1,
The upper surface of erecting bed 120 is stretched out in connection end 210 after installation through-hole 121.In the present embodiment, fixation kit includes nut
310 with screw 320, be provided with external screw thread on the outer wall of connection end 210, internal thread, nut be provided with the inwall of nut 310
310 are set on the outer wall of connection end 210, and are connected through a screw thread with connection end 210, and the external diameter of nut 310 is more than installation through-hole 121
Internal diameter, enables the upper surface of erecting bed 120 to carry out nut spacing, limitation fittings body 200 and the longitudinal direction in 100 1 directions of suspension ring
Relative displacement, and then prevent connection end 210 from being come off from installation through-hole 121.Four groups of use are evenly arranged with the outer wall of nut 310
In mounting screw 320 counterbore and with counterbore identical unthreaded hole, screw 320 is by counterbore and unthreaded hole by nut 310 with being connected
