[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the upper, lower, left, right, front, rear, inner, outer and other orientation terms that appear or will appear in this invention are only based on the drawings of this invention, and they do not specifically limit this invention.

[0024] As Figures 1-4 shown, the present utility model includes a cable 1 and an anchor 2 for anchoring the cable 1, and the anchor 2 is provided at both ends of the cable 1; the cable 1 includes a steel wire group 11 and a protective sleeve 12 provided on the outer surface of the steel wire group 11; the steel wire group 11 is formed by twisting a plurality of steel wires, and the overall shape A of the cross-section of the steel wire group 11 is a polygon; the protective sleeve 12 includes a winding tape 12a in direct contact with the steel wire group, an inner sheath 12b provided on the surface of the winding tape 12a, and an outer sheath 12c sleeved on the surface of the inner sheath 12b; a spiral wire 12d is wound on the surface of the outer sheath 12c.

[0025] Preferably, the steel wires of the steel wire group 11 are galvanized steel wires, zinc-aluminum alloy steel wires or epoxy-coated steel wires.

[0026] In order to improve the strength of the steel wire group 11, the overall shape A of the cross-section of the steel wire group 11 is a regular hexagon, which provides a more uniform stress distribution and reduces the risk of damage caused by local stress concentration. The steel wires can be arranged more closely, improving the space utilization rate, so that the total cross-sectional area of the steel wires in the steel wire group 11 is increased without increasing the external dimensions, thereby enhancing the load-bearing capacity.

[0027] It should be noted that the spiral wire 12d can reduce the influence of wind-rain induced vibration. Wind-rain induced vibration is a complex vibration phenomenon that may occur in a stay cable member under the combined action of wind and rain. This phenomenon will change the aerodynamic characteristics of the cable, causing it to lose stability in the air flow and thus generating large-amplitude vibrations. The spiral wire 12d can disrupt the air flow and reduce the excitation. By reducing the vibration, setting the spiral wire 12d helps to improve the safety and reliability of the cable 1.

[0028] The anchor 2 includes an anchor cup 21, a sealing cylinder 22 and an extension cylinder 23; the anchor cup 2 is used to fix the end of the cable 1, and the anchor cup 2 is also provided with a cover plate 21a for sealing the bottom; an anchor plate 21b for fixing the steel wire group 11 is arranged in the anchor cup 21; an anchor cup nut 21c is threadedly connected to the outer wall of the anchor cup 21; the sealing cylinder 22 and the extension cylinder 23 are sleeved on the surface of the cable 1, one end of the sealing cylinder 22 is threadedly connected to the inner wall of the anchor cup 21, and the other end is threadedly connected to the inner wall of the extension cylinder 23.

[0029] Preferably, the inner sheath 12a and the outer sheath 12b are made of high-density polyethylene, and the inner sheath 12a and the outer sheath 12b can slide freely between each other. More preferably, the inner sheath 12a is made of black high-density polyethylene, and the outer sheath 12b is made of colored high-density polyethylene.

[0030] It should be noted that due to temperature changes, the materials may expand or contract. The inner sheath 12b and the outer sheath 12c can slide freely between each other, allowing a certain amount of movement space to adapt to the dimensional changes caused by temperature changes, and avoiding sheath damage or stress concentration in the cable structure due to thermal expansion and contraction. When affected by the external environment, such as ultraviolet radiation, temperature changes or mechanical friction, the free sliding of the inner sheath 12b and the outer sheath 12c helps to disperse stress, reduce damage and extend the service life. It can also serve as a shock-absorbing mechanism to reduce the impact on the anchor 2 and the bridge structure during vibration, and also helps to reduce the noise caused by vibration.

[0031] Preferably, the winding tape 12a is made of reinforcing fibers. The steel wire group 11 is coated with an anti-corrosion coating. The winding tape 12a made of reinforcing fiber material provides additional tensile strength and durability, protecting the steel wire group 11 from mechanical damage. And the steel wire group 11 is coated with an anti-corrosion coating, adding an additional anti-corrosion layer and further improving the corrosion resistance of the cable 1.

[0032] In order to ensure the precise fit between the steel wire group 11 and the anchor plate 21b and improve the anchoring efficiency and reliability, the anchor plate 21b is provided with steel wire holes through which the steel wires of the steel wire group 11 pass.

[0033] An annular backing plate 21d sleeved on the surface of the cable 1 is further arranged in the anchor cup 21, and the annular backing plate 21d in the anchor cup 21 provides additional anchoring for the cable 1 and also serves as a buffer between the anchor cup 21 and the sealing cylinder 22, helping to reduce the local stress concentration of the cable 1.

[0034] To strengthen the tight fit between the cable 1 and the anchor 2 and improve the overall stability, the anchor 2 further includes a compression ring 24, and one end of the compression ring 24 is threadedly connected to the inner wall of the extension cylinder 23.

[0035] The anchor 2 further includes a heat shrinkable sleeve 25, and the heat shrinkable sleeve 25 is sleeved on the surfaces of the extension cylinder 23 and the compression ring 24. The heat shrinkable sleeve 25 provides sealing and insulation functions, reduces the influence of environmental factors on the extension cylinder 23 and the compression ring 24, and also helps to prevent the intrusion of moisture and corrosive substances.

[0036] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
