The utility model discloses reduce the contact stress of ring body both ends with adjacent chain link greatly, improved mooring anchor chain link's atress situation, prolonged mooring anchor chain link's life, simultaneously greatly reduced mooring anchor chain link's percentage elongation, the vertical plastic deformation of ring body volume has improved ring body intensity when having reduced tensile test to promote product quality, reduced the product rejection rate. Before the improvement, 12.7 times long of being ring diameter d of ring body unloading improve 12.49 times long of only being ring diameter d of posterior annulus body unloading, and ring body unloading meropodium economizes 1.64% to greatly reduced manufacturing cost.
Description
Technical field
The utility model relates to a kind of Offshore Engineering mooring component used, especially a kind of mooring anchor chain link.
Background technology
Mooring anchor chain is Offshore Engineering device (oil drilling platform, the single point mooring unit etc.) vitals that mooring is fixing in ocean, and be related to the safety of Offshore Engineering device, mooring anchor chain is formed by connecting by multiple mooring anchor chain link is supporting.As shown in Figure 1, existing mooring anchor chain link comprises ring body 1 and is positioned at the crosspiece 2 of ring body 1 inner central, wherein ring body 1 outline is the ellipse of longitudinal two terminal circle arc head, its both lateral sides arc-shaped side 11 external arc radius of curvature R is 7.6d (d is ring body diameter), and arc-shaped side Inner arc radius of curvature r is 6.6d.In the use procedure of mooring anchor chain link, stress mainly concentrates on the contact position of the longitudinal two ends of ring body 1 and contiguous links, by the restriction of existing mooring anchor chain link structure, the contact stress of the longitudinal two ends of ring body 1 and contiguous links is bigger than normal, and stress is concentrated, greatly have impact on the service life of mooring anchor chain link, the stretch ratio of mooring anchor chain link is also higher simultaneously, during tensile test, the plastic deformation of ring body longitudinal direction is larger, ring body longitudinal length is easily overproof, cause waste product to increase, add the ring body high material consumption of circular arc head ellipse, these add productive costs all virtually.
Utility model content
The purpose of this utility model is to provide that a kind of cost is low, the mooring anchor chain link of long service life.
The utility model is achieved by the following technical programs:
A kind of mooring anchor chain link, comprise ring body and the crosspiece being fixed on ring body inner central, described ring body outline is that the arc head of longitudinal two ends symmetry and the common four arcs of arc-shaped side of both lateral sides symmetry kiss the ellipse connect, and described ellipse is that the jujube core shape of the sharp arc head of longitudinal two ends symmetry and the perfectly round arc-shaped side of both lateral sides symmetry is oval.
The purpose of this utility model can also be realized further by following technical measures.
Aforesaid mooring anchor chain link, wherein said sharp arc head external arc radius of curvature R 1 is 1.6 ~ 1.7 times of ring body diameter d, and sharp arc head Inner arc radius of curvature r1 is 0.6 ~ 0.7 times of ring body diameter d.
Aforesaid mooring anchor chain link, wherein said perfectly round arc-shaped side external arc radius of curvature R 2 is 4 ~ 5 times of ring body diameter d, and perfectly round arc-shaped side Inner arc radius of curvature r2 is 3 ~ 4 times of ring body diameter d.
Aforesaid mooring anchor chain link, in the middle part of the perfectly round arc-shaped side Inner arc in its middle rail both sides, between tangent line, angle β is 22 ° ~ 25 °.
Aforesaid mooring anchor chain link, wherein said β is 24 °.
The ellipse of the utility model ring body outline is the jujube core shape ellipse of longitudinal two ends point arc head and the perfectly round arc-shaped side of both lateral sides, because the longitudinal two ends of ring body change the larger sharp arc head of curvature into by the circular arc head that curvature is less, the perfectly round arc-shaped side external arc of ring body both lateral sides and Inner arc radius of curvature all reduce simultaneously, substantially reduce the contact stress of ring body two ends and contiguous links, contact stress reduces 9.52%, thus substantially improve the force-bearing situation of mooring anchor chain link, extend the service life of mooring anchor chain link; The stretch ratio of mooring anchor chain link reduces 41.32%.During tensile test, the longitudinal amount of plastic deformation of ring body is little, improves ring body intensity, thus improves product design, reduce product reject rate.Before improvement, 12.7 times that ring body blanking length is ring body diameter d, long 12.49 times of being only ring body diameter d of ring body blanking after improving, every root timber material conservation 1.64%, greatly reduces productive costs.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing mooring anchor chain link;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 2, the utility model comprises ring body 3 and is fixed on the crosspiece 2 of ring body 3 inner central, and ring body 3 outline is that the sharp arc head of longitudinal two ends symmetry and the common four arcs of perfectly round arc-shaped side of both lateral sides symmetry kiss the jujube core shape ellipse connect.
Wherein sharp arc head 31 external arc radius of curvature R 1 is 1.6 ~ 1.7 times of ring body diameter d, point arc head 31 Inner arc radius of curvature r1 is 0.6 ~ 0.7 times of ring body diameter d, perfectly round arc-shaped side 32 external arc radius of curvature R 2 is 4 ~ 5 times of ring body diameter d, and perfectly round arc-shaped side 32 Inner arc radius of curvature r2 is 3 ~ 4 times of ring body diameter d.In the present embodiment, R1 is 1.65d, r1 be 0.65d, R2 be 4.5d, r2 is 3.5d; Crosspiece 2 is bone shape crosspiece, and in the middle part of the Inner arc of the perfectly round arc-shaped side 32 in crosspiece 2 both sides, between tangent line, angle β is 22 ° ~ 25 °, in the present embodiment, and β is 24 °.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
