[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a vibration reduction auxiliary cable device for cable-stayed bridges, comprising a cable 1, which is fixedly sleeved on the cable 2 of the cable-stayed bridge;

[0027] The vibration damping mechanism is installed between two adjacent stay cables 2 of the cable-stayed bridge. The two ends of the vibration damping mechanism are respectively connected and fixed to the slings 1 on the two adjacent stay cables 2.

[0028] The tensioning assembly is mounted on the vibration damping mechanism and is used to apply prestress to the vibration damping mechanism.

[0029] Auxiliary cable 3, one end of which is fixedly installed on the main beam 5 of the cable-stayed bridge by anchor 4, and the other end of which is fixedly connected to the loop 1 on the lowest cable-stayed cable 2, and the auxiliary cable 3 is set perpendicular to the lowest cable-stayed cable 2.

[0030] In use, the vibration damping mechanism is installed on the stay cable 2 via the lasso 1, and multiple vibration damping mechanisms in the same group are connected in series between the stay cables 2, so that multiple stay cables 2 are connected together through multiple vibration damping mechanisms to form a cable net structure, which improves the overall strength. Moreover, when the stay cables 2 vibrate due to external forces, the vibration damping mechanism can achieve vibration damping and buffering, thereby improving the buffering and absorption effect of the cable-stayed bridge on impacts. Furthermore, by setting the auxiliary cable 3, the stay cables 2 and the multiple vibration damping mechanisms connected as a whole can be tensioned and fixed again. This not only helps to improve the overall support strength between the stay cables 2, but also ensures that the positions of the vibration damping mechanism and the lasso 1 are not easily changed, thereby ensuring the overall stability of the cable-stayed bridge.

[0031] As a preferred embodiment: to ensure the vibration reduction performance of the stay cable 2, the vibration reduction mechanism includes two vibration reduction units, one end of each of the two vibration reduction units is connected to the same cable 1; each of the two vibration reduction units includes a vibration reduction component, both ends of the vibration reduction component are connected to a connecting cable 6, the end of the connecting cable 6 is fixedly connected to a first clamp 7, the two first clamps 7 are respectively fixedly sleeved on the cable 1 of the two adjacent stay cables 2, and the tensioning component is set between the two vibration reduction components;

[0032] The vibration damping component is installed on the loop 1 of the stay cable 2 through the connecting cable 6 and the first clamp 7, so that the stay cable 2 and the vibration damping component form a cable net structure, which helps to improve the support strength of the stay cable 2. Moreover, by tensioning the vibration damping component through the tensioning component, the tension of the vibration damping component can be adjusted, which can effectively suppress the vibration of the stay cable 2 caused by external excitation and improve the buffering and absorption of the stay cable 2 for impact.

[0033] As a preferred embodiment: to improve the vibration reduction effect of the vibration damping component, the vibration damping component includes a first sleeve 8, with friction blocks 9 slidably disposed at both ends of the first sleeve 8, and two connecting cables 6 fixedly connected to the two friction blocks 9 respectively; a spring 10 is sleeved on the connecting cable 6, the spring 10 is disposed inside the first sleeve 8, and the two ends of the spring 10 abut against the friction blocks 9 and the first sleeve 8 respectively; a damping element is disposed between the two friction blocks 9, and the two ends of the damping element are fixedly connected to the two friction blocks 9 respectively; the two ends of the tensioning component are fixedly connected to the two first sleeves 8 respectively.

[0034] The vibration of the stay cable 2 is transmitted to the damping component through the connecting cable 6. At this time, the friction block 9 slides in the first sleeve 8 under the action of the connecting cable 6. Energy can be dissipated through the friction between the friction block 9 and the first sleeve 8. At the same time, the friction block 9 will compress the spring 10 while sliding, thereby buffering the friction block 9. Moreover, when the friction block 9 slides, the damping component between the two friction blocks 9 will also buffer the friction block 9, thereby improving the buffering and absorption of the stay cable 2 against the impact.

[0035] To improve the buffering effect of the damping component, the damping component includes a second sleeve 11. Connecting rods 12 are slidably sleeved on the inner sides of both ends of the second sleeve 11. One end of the connecting rod 12 is fixedly connected to the side of the friction block 9 away from the connecting cable 6, and the other end of the connecting rod 12 is fixedly connected to a piston head 13. The piston head 13 is slidably connected inside the second sleeve 11, and the two piston heads 13 are in contact with each other. A tension spring 14 is sleeved on the outer side of the second sleeve 11, and the two ends of the tension spring 14 are fixedly connected to the two friction blocks 9 respectively.

[0036] When the friction block 9 slides under the action of the connecting cable 6, it will drive the piston head 13 to slide in the second sleeve 11 through the connecting rod 12. By utilizing the sealing between the piston head 13 and the second sleeve 11, the space between the two piston heads 13 can be in a vacuum state after the piston head 13 is separated under the action of external force, thereby achieving buffering of the friction block 9. Moreover, during this process, the tension spring 14 between the two friction blocks 9 extends, and the tension spring 14 can further improve the buffering effect of the friction block 9.

[0037] As a preferred embodiment, a sealing structure is provided between the connecting rod 12 and the second sleeve 11. The sealing structure can be achieved by setting a sealing ring at the end of the second sleeve 11.

[0038] By sealing the connection between the connecting rod 12 and the second sleeve 11, the air inside the second sleeve 11 cannot be discharged when the piston head 13 moves, thereby compressing the air using the piston head 13, thus increasing the energy dissipation for the vibration of the cable 2.

[0039] As a preferred embodiment, the tensioning assembly includes a connecting sleeve 15. The inner wall of the connecting sleeve 15 has a forward thread and a reverse thread at both ends. The two ends of the connecting sleeve 15 are threadedly connected to a screw 16. The end of the screw 16 is fixedly connected to a second clamp 17. The second clamp 17 is fixedly sleeved on the outer wall of the first sleeve 8, and the screw 16 is perpendicular to the first sleeve 8.

[0040] As a preferred embodiment: the first clamp 7 and the second clamp 17 have the same structure and each includes two symmetrically arranged clamp bodies 18. Both clamp bodies 18 are provided with connecting holes for connecting bolts. The two clamp bodies 18 are connected and fixed by bolts. Both ends of the clamp body 18 are fixedly connected with connectors 19. The connectors 19 are semi-cylindrical structures. The connectors 19 on the two clamp bodies 18 are joined together to form a connecting cylinder. The inner wall of the connecting cylinder is provided with anti-slip texture. The connecting cable 6 is fixedly connected inside the connecting cylinder.

[0041] As a preferred embodiment, the anti-detachment component includes an installation chamber 23. Four sets of installation chambers 23 are provided on the outer side of the first sleeve 8, and one end of the front of the installation chamber 23 is transparent. Two sets of installation chambers 23 are provided with two sets of guide wheels 22 and a first guide cable 21 for guiding engagement on the inner side of each set of installation chambers 23. The other two sets of installation chambers 23 are provided with a scale plate 27, a guide block 26 and a guide groove on the inner side of each set of installation chambers 23. The two sets of guide blocks 26 slide in engagement on the inner side of the guide groove. The two sets of guide blocks 26 are provided with a second guide cable 24 and a buffer spring 25 elastically connected to the installation chamber 23 on the side away from each other. A connecting plate 20 is installed on the outer side of the two sets of connecting cables 6. The two sets of first guide cables 21 and the two sets of second guide cables 24 are fixedly connected to the connecting plate 20. The bottom of the two sets of guide blocks 26 is provided with a pointer, and the pointer engages with the scale plate 27.

[0042] A method for using a vibration-damping auxiliary cable device for a cable-stayed bridge includes the following steps:

[0043] S1. Determine the installation position and length of cable 2 and install cable 2;

[0044] S2. Tension and adjust the inclination angle of the installed stay cable 2;

[0045] S3. Determine the installation location of the vibration damping auxiliary cable equipment and install the vibration damping auxiliary cable equipment; during the installation process, when the connecting cable 6 is connected to the first clamp 7 and when the screw 16 is connected to the second clamp 17, apply adhesive to the inner wall of the connecting cylinder of the first clamp 7 and the second clamp 17, and weld and fix the connecting cable 6 to the first clamp 7 and the screw 16 to the second clamp 17.

[0046] S4. Based on the tension of cable 2, tension the vibration damping mechanism of the vibration damping auxiliary cable device using the tensioning assembly;

[0047] S5. Protect and lubricate the stay cables 2 and vibration damping auxiliary cables. Protecting the stay cables 2 and vibration damping auxiliary cables includes anti-corrosion treatment of the surface of the stay cables 2 and the surface of the vibration damping auxiliary cables, as well as regular inspection and maintenance. Lubrication involves injecting lubricating oil into the stay cables 2, auxiliary cables 3 and connecting cables 6 to reduce frictional resistance and wear, thus completing the construction.

[0048] Example 1, as Figures 1-4 As shown, the two ends of the connecting sleeve 15 are threaded with screws 16, and the ends of the screws 16 are fixedly connected with a second clamp 17. The second clamp 17 is fixedly sleeved on the outer wall of the first sleeve 8, and the screws 16 are set perpendicular to the first sleeve 8. In use, the end of the screw 16 away from the connecting sleeve 15 is inserted into the connecting sleeve of the second clamp 17 and welded to fix it. When it is necessary to adjust the tension of the two damping components, simply rotate the connecting sleeve 15 to make the two screws 16 move in opposite directions, thereby adjusting the distance between the two damping components and realizing the tension adjustment of the damping components.

[0049] Example 2, as Figure 3As shown, when the connection between the connecting cable 6 and the friction block 9 and the damping component becomes loose or breaks, the connecting plate 20 can be used to drive the first guide cable 21 to stretch under the guidance of the two sets of guide wheels 22. A counterweight ring and a buffer washer are provided at the bottom end of the first guide cable 21, causing the buffer washer to drive the bottom end of the first guide cable 21 to contact and position with the mounting chamber 23. This, in conjunction with the connecting plate 20, limits the loosening position of the connecting cable 6, preventing the connecting cable 6 from detaching from the inside of the first sleeve 8. Simultaneously, the second guide cable 24 drives the guide block 26 to move in the guide groove, and also drives the buffer spring... Spring 25 is elastically compressed to form an auxiliary vibration damping structure, which buffers and dampens the connecting cable 6 subjected to external forces. The pointer and scale plate 27 are designed to facilitate maintenance personnel to judge the tension state of the auxiliary cable by using the transparent structure of the end face of the second guide cable 24 and the threshold of the tension state of the first guide cable 21 and the second guide cable 24 during maintenance. This allows maintenance personnel to observe the internal structure of the vibration damping mechanism from the outside of the structure to detect structural loosening or breakage, thus enabling subsequent maintenance work. This achieves the function of preventing the vibration damping auxiliary structure from locking up and facilitates the detection of the working status of the enclosed structure.

[0050] In summary, the vibration damping auxiliary cable device of this utility model is connected in series between the stay cables 2, and the vibration damping auxiliary cable device and the stay cables 2 are cross-connected to form a cable net structure system, which improves the support strength and vibration damping performance of the stay cables 2. At the same time, the stay cables 2 are connected by a vibration damping mechanism, which is conducive to increasing the vibration damping between adjacent groups of stay cables 2. The vibration absorption of the stay cables 2 by the vibration damping mechanism can effectively reduce the vibration amplitude of the stay cables 2 and improve the seismic performance of the overall cable-stayed bridge. In addition, the setting of the tensioning component can effectively suppress the vibration of the stay cables 2 caused by external excitation, and improve the buffering and absorption effect of the cable-stayed bridge on impact.

[0051] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
