The drawings described herein are used to provide a further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please are not constituted an undue limitation on the present application for explaining the application.In the accompanying drawings:
Fig. 1 be the invention relates to for harbour stop elastic mooring cable structural schematic diagram；
Component and reference signs list:
1 packthread, 2 stretch cords, 3 fixing belts, 4 protective cases, 5 rope slings, 6 adjusting sets.
Specific embodiment
For the clearer general idea for illustrating the application, carry out in an illustrative manner with reference to the accompanying drawings of the specification detailed
It describes in detail bright.
It can be more clearly understood that the above objects, features, and advantages of the application, with reference to the accompanying drawing and specific implementation
The application is further described in detail in mode.It should be noted that in the absence of conflict, embodiments herein
And the feature in embodiment can be combined with each other.
Many details are explained in the following description in order to fully understand the application, still, the application may be used also
To be implemented using other than the one described here other modes, therefore, the protection scope of the application is not by described below
Specific embodiment limitation.
As shown in fig. 1, the elastic mooring cable provided by the present application stopped for harbour, the package including hollow setting
Rope 1, and set on the stretch cord 2 of 1 middle inside of packthread, packthread 1 is in loose shape, gives stretch cord 2 and provides the sky stretched
Between.In above structure, stretch cord 2 has preferable elasticity, the intensity with higher of packthread 1, the bullet when cable receives drawing-off
The stress first of power rope 2, the packthread 1 of outer layer is stretched therewith after stretch cord 2 stretches to a certain extent, is equivalent to and increases cable
Integral, flexible coefficient carries out returning for grading absorption, the impact force of buffering ship transmitting, and cable to the impact force that ship receives
Bullet is stablized, and the steady dragging to ship is realized.
Specifically, the both ends of stretch cord 2 are connected with packthread 1.In order to guarantee that stretch cord 2 is securely connect with packthread 1, In
Wherein in an embodiment, be enclosed with fixing belt 3 on the outside of the packthread 1 of corresponding 2 end of stretch cord, the end of stretch cord 2 with
Fixing belt 3, packthread 1 are stitched together, it is preferred to use axial suture way.When the drafting force duration that cable is subject to increases
When, what is disconnected first is the suture location of stretch cord 2 Yu packthread 1, and user just needs to take it after finding disconnection
He remedies in measure, and preventing drafting force to be further continued for increase causes packthread 1 to disconnect.That is, above-mentioned stretch cord 2 and package
The connection relationship of rope 1 can play effective early warning to the service condition of cable and remind, and ensure that the safety of ship.
In a wherein embodiment, be equipped with protective case 4 in the outer sheath of fixing belt 3, for reduce cable and ship it
Between friction.In a preferred embodiment, fixing belt 3 is knitted to form by polyester filament or polypropylene multifilament, the width of fixing belt 3

Example is added to extruder, squeezes out after being melted, being plasticized and plastic monofilament is made；
The plastic monofilament that S1.2 obtains more step S1.1 is twisted, and is obtained positive twisted filament beam and reverse lay tow, is contained in every thread tow
There is 15-30 root plastic monofilament, the twist of every thread tow is 15-45 twists/m；
S1.3 is knitted in advance: obtain strand by 1-3 that step S1.2 is obtained thread with orientation tow and for one, obtained positive twirl strand and
The quantity of reverse lay strand is equal；
S1.4 is woven into rope:
It weaves to obtain packthread using twill weave structure, the braiding number of spindles of packthread is 8-32 ingot.
8. the elastic mooring cable according to claim 1-5 stopped for harbour, which is characterized in that the bullet
The preparation method of power rope includes the following steps:
S2.1 is knitted in advance:
It by 3-10 root polyester filament and/or Tynex and is a strand yarn of exodermis, by 120-280 root rubber thread parallel
It arranges and is inner sandwich layer；
S2.2 knitting forming:
The rope yarn that step S2.1 is obtained is knitted to form exodermis according to twill weave structure or weft-knitting structure, exodermis
Braiding number of spindles is 16-32 ingot；While weaving exodermis, the inner sandwich layer that step S2.1 is obtained is long with 1.5-2.0 times of drawing-off
Degree is at the uniform velocity input in exodermis, and the stretch cord is made.
9. the elastic mooring cable according to claim 7 stopped for harbour, which is characterized in that
In step S1.1, the melt flow rate (MFR) of the wire drawing grade polypropylene particle is 2.0-8.0g/10min, and wire drawing grade is linear
The melt flow rate (MFR) of high density polyethylene (HDPE) particle is 0.5-1.0g/10min；
In step S1.1, the average diameter of the obtained plastic monofilament is 0.22-0.3mm, and the mean break of plastic monofilament is strong
Degree is 5-7g/D；
In step S1.1, the weight accounting of the wire drawing grade polypropylene particle and/or wire drawing grade linear high-density polyethylene particle
For 30%-99%.
10. the elastic mooring cable according to claim 8 stopped for harbour, which is characterized in that in step S2.1, institute
The average linear density for stating polyester filament and/or Tynex is 1000D-3000D；The average diameter of the rubber thread is 0.5-
1.0mm。
