[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Reference below Figure 1-Figure 4 A cable according to an embodiment of the present invention is described.

[0027] The present invention proposes a large deformation composite cable based on the cooperative deformation of an elastomer, the large deformation composite cable comprises a cable body 10 and an elastomer 30, the cable body 10 comprises a first connecting part 11, a second connecting part 12 and a deformation part 13; the first connecting part 11 and the second connecting part 12 are suitable for connecting a cable installation anchor to bear and transmit tension; the deformation part 13 connects the first connecting part 11 and the second connecting part 12; the cable body 10 is constructed as a plurality of, and the large deformation composite cable forms a force axis when subjected to tension; the plurality of cable bodies 10 are arranged at circumferential intervals about the force axis; the deformation part 13 protrudes in a plane perpendicular to the force axis, and the plurality of deformation parts 13 form a deformation cavity 20 around the force axis; the elastomer 30 is arranged in the deformation cavity 20, and the deformation part 13 is suitable for deforming and squeezing the elastomer 30 when the large deformation composite cable is subjected to tension.

[0028] According to the large deformation composite cable of the present application, the deformation part 13 protrudes in a plane perpendicular to the force axis, and a plurality of deformation parts 13 form a deformation cavity 20 around the force axis. In this embodiment, when the first connection part 11 and the second connection part 12 of the large deformation composite cable are subjected to force, the tension will be transmitted to the deformation part 13, and the deformation part 13 has a tendency to shrink into the deformation cavity 20 under the action of the tension and to stretch along the force axis. Therefore, the large deformation composite cable has good deformation ability and can undergo a large deformation under the action of tension. The elongation performance of the large deformation composite cable is improved by deformation, and the tensile performance of the large deformation composite cable can be improved, thereby overcoming its brittle characteristics and avoiding being directly broken, so that the large deformation composite cable can be suitable for working conditions with high requirements for deformation ability. At the same time, the elastomer 30 is arranged in the deformation cavity 20. When the deformation part 13 contracts inwardly, it will squeeze the elastomer 30, and the elastomer 30 will be deformed cooperatively. At the same time, the elastic force of the elastomer 30 reacts on the deformation part 13, which can inhibit its inward contraction to a certain extent, slow down its deformation, avoid sudden changes in the large deformation composite material cable, increase the stability of the large deformation composite material cable, and improve the load-bearing capacity of the large deformation composite material cable during the deformation process under the condition of certain deformation capacity, so that it is suitable for more working conditions.

[0029] It should be noted that in the related art, the deformation capacity of the composite cable generally only comes from the elastic deformation of the material itself. The elastic deformation capacity of the fiber-reinforced composite materials commonly used for cables is relatively small. For example, the common carbon fiber reinforced composite materials have an elastic deformation capacity of only 1%-2%. However, the present application improves the structure of the composite cable and combines the coordinated deformation of the elastomer 30 to enable the entire composite cable to achieve a larger deformation amount. In some embodiments, the deformation amount can reach 5%-10%. Therefore, the composite cable of the present application has a large deformation capacity and is a large deformation composite cable.

[0030] According to the large deformation composite cable of the present application, due to the presence of the deformation cavity 20, the large deformation composite cable has good deformation ability, can improve the extension performance and tensile performance of the large deformation composite cable through deformation, avoid being directly broken, and can be applied to working conditions with high requirements for deformation ability; at the same time, the elastic body synergistically deforms, which can delay the deformation process, increase the stability of the large deformation composite cable, and also improve the load-bearing capacity of the large deformation composite cable during the deformation process. The large deformation composite cable of the present application has good stability and reliability, and can meet the requirements of specific application fields for cable deformation ability.

[0031] According to some embodiments of the present application, the elastic body 30 is formed with a recess 31 that matches the deformation portion 13 , and at least a portion of the deformation portion 13 is located in the recess 31 to limit the circumferential movement of the deformation portion 13 relative to the elastic body 30 along the force axis.

[0032] In this embodiment, since the elastic body 30 is disposed in the deformation cavity 20 surrounded by the deformation portion 13, the elastic body 30 and the deformation portion 13 are at least partially in contact with each other. Figure 2 As shown, by providing a recess 31 and placing at least a portion of the deformation portion 13 in the recess 31, the circumferential movement of the deformation portion 13 relative to the elastic body 30 along the force axis can be limited, thereby preventing the deformation portion 13 from slipping and preventing the elastic body 30 from detaching from the gap between the multiple deformation portions 13 to form a large deformation composite cable.

[0033] According to some embodiments of the present application, the elastomer 30 is provided with multiple pressure gaskets corresponding one-to-one to the deformation parts 13, and each pressure gasket is arranged between the elastomer 30 and one of the multiple deformation parts 13 to be suitable for bearing the pressure applied by the deformation part 13 and dispersing it to the elastomer 30.

[0034] Since the contact area between the deformation part 13 and the elastic body 30 is limited, the pressure applied by the deformation part 13 to the elastic body 30 is relatively concentrated, and there is a situation where the pressure of the contact part is too large to damage the elastic body 30, and it is not conducive to the elastic deformation of the elastic body 30 as a whole. In view of this problem, in this embodiment, by arranging a pressure gasket (not shown in the drawings) between the elastic body 30 and the deformation part 13, the pressure gasket is subjected to the pressure of the deformation part 13, and then the pressure is transmitted to the elastic body 30, so that the force of the elastic body 30 can be dispersed, and then the deformation of the elastic body 30 can be made more uniform. In this embodiment, the shape of the pressure gasket is not limited, but the contact area between the pressure gasket and the elastic body 30 will affect the effect of pressure dispersion, and a specific design can be made accordingly in practice. In some embodiments, the above-mentioned recess 31 may be provided with a pressure gasket, which is connected to the elastomer 30, and the deformation portion 13 abuts against the pressure gasket; the pressure gasket and the elastomer 30 may be connected in a variety of ways such as embedding, bonding, etc., but it should be noted that the connection should not limit the deformation of the elastomer 30 to ensure that the large deformation composite cable can be deformed normally.

[0035] It should be noted that the elastic body 30 in the present application can be constructed as an elastic material piece formed by a hard elastic material to adapt to the shape of the deformation cavity 20, and can also be constructed as an elastic structural piece with elastic properties such as a spring.

[0036] According to some embodiments of the present application, the large deformation composite cable further includes a damping member, which is disposed inside the elastic body 30. In this embodiment, when the large deformation composite cable vibrates under the action of external environmental forces, the damping member can reduce vibrations of the overall structure of the large deformation composite cable, thereby improving the stability and adaptability of the large deformation composite cable.

[0037] In addition, the elastic body 30 of this embodiment is combined with the damping element, so that the stiffness and deformation capacity of the elastic body 30 can be variable and controllable. By changing the elastic body 30 and the damping element, the overall performance of the large deformation composite cable can be adjusted.

[0038] In this embodiment, the damping force direction of the damping member can be set to be directly opposite to the deformation portion 13, so as to better exert the damping effect.

[0039] In some embodiments, the elastic body 30 is constructed as a plurality of springs radially spaced around the force-bearing axis, each spring corresponds to a deformation portion 13, the inner diameter ends of the plurality of springs are connected, the outer diameter end of each spring can directly abut the deformation portion 13 or the pressure gasket, or can abut the deformation portion 13 or the pressure gasket through an elastic coating layer, the spring bears the pressure applied by the deformation portion 13 along its elastic force direction, and reacts to the deformation portion 13 through elastic force, so as to better exert the elastic effect of the elastic body 30. Furthermore, the outer sides of the plurality of springs can be coated with an elastic coating layer to facilitate the installation and use of the springs, while improving the coordination of the deformation of the plurality of springs.

[0040] According to some embodiments of the present application, the cable body 10 is constructed as a fiber-reinforced composite material, which includes fibers, which are configured as a plurality of fibers extending along the force axis, and at least part of the fibers protrude in a direction perpendicular to the force axis. In the present embodiment, the cable body 10 is constructed as a fiber-reinforced composite material, which is a composite material formed by laminating, molding or pultruding a reinforcing fiber material, such as glass fiber, carbon fiber, aramid fiber, etc., with a matrix material. Specifically, the cable body 10 is a structure with multiple fiber layers formed by curing a unidirectional fiber prepreg according to a prefabricated template. It should be noted that the unidirectional fiber prepreg is a composite material made of fiber tows and resin through processes such as coating, hot pressing, cooling and laminating. The extension direction of the fiber is consistent with the morphological extension direction of the cable body 10, which is manifested as extending along the force direction at the first connection part 11 or the second connection part 12, and protruding perpendicularly to the force direction at the deformation part 13 to extend along the morphological direction of the deformation part 13; when the large deformation composite cable is subjected to force, the tension will be transmitted along the extension direction of the fiber. The cable body 10 of the large deformation composite cable in this embodiment has excellent mechanical properties, and can maintain processing consistency through curing and forming.

[0041] According to some embodiments of the present application, each cable body 10 is made of a plurality of strands, each strand is constructed as a fiber-reinforced composite material including a plurality of fibers, and the fibers of each strand extend along the extension direction of the strand. The cable body 10 of this embodiment can improve the performance and application range of large deformation composite cables.

[0042] According to some embodiments of the present application, the deformation cavity 20 is configured as a plurality of deformation cavities 20 arranged at intervals along the force axis direction. In this embodiment, by providing a plurality of deformation cavities 20, the large deformation composite cable can have a plurality of deformation parts, and the deformation capabilities of the plurality of deformation parts are superimposed on each other, so that the large deformation composite cable has a greater deformation capability, and the tensile effect of the large deformation composite cable is better improved. Furthermore, by providing a plurality of deformation cavities 20, the deformation can be dispersed to each deformation part, reducing the deformation pressure of a single deformation part, and at the same time reducing the processing and installation pressure of a single deformation part, thereby improving the stability and reliability of the large deformation composite cable structure.

[0043] According to some embodiments of the present application, the large deformation composite cable also includes a constraint member 40, which forms a limiting hole 44. The limiting holes 44 are constructed to correspond one to one with the cable body 10. A portion of each first connection part 11 or a portion of each second connection part 12 is accommodated in one of the multiple limiting holes 44, so as to be suitable for converging multiple first connection parts 11 or multiple second connection parts 12.

[0044] In this embodiment, the large deformation composite cable has two connection ends suitable for connecting with the anchor, each of which is composed of a plurality of first connection parts 11 or a plurality of second connection parts 12; at the same time, the force axis of the large deformation composite cable passes through the center of the two connection ends. By arranging the restraining members 40 at the two connection ends, the plurality of first connection parts 11 or the plurality of second connection parts 12 can be gathered together, and when gathered, the protrusion of each deformation part 13 is kept toward the outer diameter side along the radial direction of the force axis to form a deformation cavity 20.

[0045] In this embodiment, when the large deformation composite cable is subjected to stress at both ends, the tension is dispersed to each cable body 10, and the deformation portion 13 of the cable body 10 is subjected to the tension of the first connection portion 11 and the second connection portion 12, and is stretched and deformed along the force axis direction and squeezes the elastic body 30; the elastic body 30 is squeezed and deformed by multiple deformation portions 13 at the same time. Further, multiple cable bodies 10 can be constructed to be identical and symmetrically arranged about the center of the force axis. When the large deformation composite cable is subjected to stress, each cable body 10 has the same deformation ability, can be deformed in coordination, and maintain synchronous deformation, thereby ensuring that each deformation portion 13 is subjected to uniform stress and ensuring the stability of the cable deformation process.

[0046] In the embodiment in which a plurality of deformation cavities 20 are provided, each cable body 10 further includes a plurality of intermediate connecting portions, each intermediate connecting portion being provided between two adjacent deformation cavities 20, and each connecting portion connecting two deformation portions 13 corresponding to two adjacent deformation cavities 20. In order to achieve stable connection of the plurality of cable bodies 10 between adjacent deformation cavities 20, a restraining member 40 is provided between adjacent deformation cavities 20 to gather the plurality of intermediate connecting portions corresponding to the plurality of cable bodies 10.

[0047] According to some embodiments of the present application, the restraining member 40 includes a first component 41, a second component 42 and a fastener 43. The first component 41 is formed with a first limiting groove, and the second component 42 is formed with a second limiting groove. The first limiting groove cooperates with the second limiting groove to form a limiting hole 44. The first component 41 and the second component 42 are suitable for approaching or moving away from each other to change the size of the limiting hole 44. The fastener 43 is arranged on the first component 41 and / or the second component 42. The fastener 43 is suitable for connecting the first component 41 and the second component 42 and for adjusting the distance between the first component 41 and the second component 42. In this embodiment, the limiting hole 44 is formed by the cooperation of the first component 41 and the second component 42 to limit the first connecting portion 11 or the second connecting portion 12, so as to prevent the dispersion of multiple cable bodies 10 when the large deformation composite cable is subjected to force, so as to ensure the stability of the large deformation composite cable structure. The size of the limiting hole 44 can be adjusted by adjusting the distance between the first component 41 and the second component 42 through the fastener 43, so that the clamping force on the first connecting part 11 or the second connecting part 12 along the radial direction of the limiting hole 44 can be adjusted to ensure the limiting effect of the limiting hole 44, while facilitating the separation or combination of the first limiting groove and the second limiting groove so that the first connecting part 11 or the second connecting part 12 can be placed in the limiting hole 44.

[0048] According to some embodiments of the present application, at least one of the first component 41 and the second component 42 is constructed as a ring centered on the force axis, and a plurality of limiting holes 44 are arranged at intervals along the circumference of the force axis. In this embodiment, by arranging the limiting holes 44 at intervals along the circumference of the force axis, the relative distance between each cable body 10 and the force axis is the same, which can ensure that the force of the multiple deformation parts 13 is uniform. Further, the limiting holes 44 can be constructed to be arranged at uniform intervals about the force axis to achieve the symmetry of the multiple cable bodies 10 about the center of the force axis. When the large deformation composite cable is subjected to force, each cable body 10 can be deformed in coordination, so that the elastic body 30 is subjected to more uniform force as a whole, and the stability of the deformation process of the large deformation composite cable is ensured.

[0049] In some embodiments, Figure 4As shown, the first component 41 is constructed as a cylindrical member, and a plurality of first limiting grooves extending in the axial direction are arranged at intervals in the circumferential direction of the first component 41; the second component 42 is constructed as an annular member, and a plurality of second limiting grooves extending in the axial direction are arranged at intervals in the circumferential direction of the inner wall of the second component 42; the first limiting grooves correspond to the second limiting grooves one by one, and cooperate to form a limiting hole 44. In order to facilitate the assembly of the first connecting part 11, the second connecting part 12 and the limiting hole 44, the second component 42 is constructed as a combination of two semi-annular members, the two semi-annular members are arranged around the first component 41, and the two ends of the semi-annular members are provided with ear plates extending in the radial direction, and a group of ear plates corresponding to the two semi-annular members are connected by a fastener 43, and the fastener 43 can adjust the radial spacing between the first component 41 and the second component 42 by adjusting the spacing between the two semi-annular members, so as to change the size of the limiting hole 44. The fastener 43 can be constructed as a bolt or a rivet for easy installation and use.
