Description

Technical Field

[0001] This invention relates to the technical field of bridge components, and more specifically, to a hanger anchoring device and a vibration reduction and isolation system. Background Technology

[0002] Urban landscape bridges, with their beautiful designs, greatly enhance the overall image of a city. With the high-quality development of urban construction in my country, an increasing number of urban landscape bridges are being built and put into use. In pursuit of aesthetic appeal, many urban landscape bridges opt for single-cable-stayed suspension bridges. In these bridges, the main cable is connected to the main girder by only a single suspender. When the bridge deck is subjected to eccentric loading, the torsional moment of inertia of the stiffening girder itself primarily resists the torque; the vertical support provided by the suspender is insufficient to effectively resist the torque. Furthermore, during bridge operation, under eccentric vehicle loads or wind loads, when the main girder experiences torsional vibration, the torsional stiffness of the stiffening girder and the support force of the suspender alone are insufficient to effectively suppress the vibration. Therefore, in the use of single-cable-stayed suspension bridges, it is necessary not only to adopt appropriate measures to improve the stress at the anchorage points of the suspenders and the main girder, but also to implement corresponding vibration reduction and isolation measures.

[0003] While existing cable anchoring technology is convenient to construct, its application to single-cable-stayed suspension bridges presents several problems: The anchorage only releases the bending moment within the longitudinal vertical section of the bridge, leaving some bending moment within the cross-section unreleased. Over time, this can lead to cable fatigue or even failure. Furthermore, the cable only provides upward support, failing to effectively control torsional deformation of the main girder. Once torsional vibration occurs, the main girder is prone to significant torsional deformation and vibration, impacting traffic safety on urban bridges. Summary of the Invention

[0004] The purpose of this invention is to provide a suspender anchoring device and a vibration reduction and isolation system that can effectively release bending moments in various directions.

[0008] Furthermore, it also includes a load-bearing pad; the suspension rod passes through the load-bearing pad so that the bottom of the load-bearing pad is connected to the base; the outer diameter of the load-bearing pad gradually increases from bottom to top.

[0010] Furthermore, the anchoring top plate is semi-circular and there are two of them, so that the two anchoring top plates can be spliced ​​into a ring; the hanger rod passes through the space between the two anchoring top plates; a limiting ring is provided at the bottom of the hanger rod and the outer diameter of the limiting ring is larger than the diameter of the through hole formed by the two anchoring top plates; the base is semi-circular and there are two of them, so that the two bases can be spliced ​​into a ring; the hanger rod passes through the space between the two bases.

[0015] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0016] In use, the suspender anchoring device of this invention suspends the anchoring top plate and the base, with the ball head housed within the recess. Simultaneously, the bridge beam is positioned above the base and supported by the bottom plate. In other words, the beam is indirectly supported by the suspender. When the bridge is eccentrically loaded, the beam rotates, causing the bottom plate to twist. Due to the complex stress conditions of the bridge, the beam may bend in multiple directions in addition to twisting. The recess in the bottom plate and the ball head of the anchoring top plate allow the bottom plate to swing relative to the anchoring top plate in any direction. This allows the suspender to adapt to any direction of beam torsion with minimal torsion, thereby releasing bending moments in any direction. Furthermore, when the bridge experiences torsional vibration, dampers installed around the bottom plate can be adjusted to reduce vibration. Attached Figure Description

[0031] Example:

[0032] like Figures 1-7As shown, the present invention provides a boom anchoring device, including a boom 1, an anchoring top plate 2, and a base 3. The anchoring top plate 2 is connected to the bottom of the boom 1. The upper end of the boom 1 is connected to the main cable, thereby suspending the various components below the boom 1 and the beam plate 16, thus effectively supporting the beam plate 16. A ball head 4 is provided on the upper part of the anchoring top plate 2. Since the torsion of the beam plate 16 is small, the required deflection angle is also small. Therefore, the ball head 4 only needs to be hemispherical or less. The base 3 is provided with a through hole for the boom 1 to pass through, so that the boom 1 passes through the base 3. The lower part of the base 3 is recessed to fit the ball head 4, so that the ball head 4 is accommodated in the recess 5 and can swing relative to the recess 5. Specifically, the recess 5 is provided with an inwardly concave spherical surface, so as to better fit the ball head 4, so that the surface of the ball head 4 is in contact with the inner wall of the recess 5. This also increases the contact area between the ball head 4 and the recess 5, thereby distributing the vertical load provided by the hanger to the contact surface of the two, preventing excessive wear.

[0033] In use, the suspender anchoring device of the present invention suspends the anchoring top plate 2 and the base 3 with the suspender 1, and the ball head 4 is housed inside the recess 5. Simultaneously, the bridge beam 16 is located above the base 3 and supported by the bottom plate. When the bridge is unevenly loaded or affected by strong winds, the beam 16 twists, which in turn causes the bottom plate to twist. Because the stress conditions of the bridge are complex, the twisting direction of the beam 16 can be arbitrary. Due to the cooperation between the recess 5 of the bottom plate and the ball head 4 of the anchoring top plate 2, the bottom plate can swing relative to the anchoring top plate 2 in any direction. This allows the suspender 1 to adapt to the arbitrary twisting direction of the beam 16 while bearing relatively small torsions, thereby releasing the bending moment at the end of the suspender 1.

[0034] In this embodiment, the beam 16 can be a steel beam 16 or a relatively thick concrete beam 16. The upper surface of the beam 16 is the bridge deck. To ensure effective deflection, the protrusion height of the ball head 4 is greater than the depth of the recess 5, so that there is a gap between the anchoring top plate 2 and the bottom plate when they are parallel. At the same time, the through hole of the base 3 is also larger than the diameter of the hanger 1, so that the hanger 1 has room to swing.

[0035] Because there is relative oscillation between the base 3 and the anchored top plate 2, and this oscillation releases the bending moment of the beam 16, several dampers 6 are provided between the anchored top plate 2 and the base 3 in this embodiment to provide damping force and thus better dissipate vibration energy. At the same time, the several dampers 6 are distributed around the hanger 1 to ensure balanced force distribution.

[0036] This embodiment also includes a load-bearing pad 7. The hanger 1 passes through the middle of the load-bearing pad 7. The load-bearing pad 7 is located above the base 3 and its bottom is connected to the base 3. The outer diameter of the load-bearing pad 7 gradually increases from bottom to top. This allows the supporting force of the hanger 1 on the beam 16 to be distributed to a larger area of ​​the bottom surface of the beam 16 through the load-bearing pad 7. While reducing the pressure, it also increases the lever arm length of the support, thereby providing additional torsional moment of inertia and enhancing the torsional performance of the stiffening beam.

[0037] In this embodiment, an anchoring base plate 8 is also provided on the top of the load-bearing pad 7. The lower surface of the beam plate 16 is connected to the upper surface of the anchoring top plate 2. The hanger 1 passes through the anchoring base plate 8. The area of ​​the anchoring base plate 8 is larger than the area of ​​the top of the load-bearing pad 7, which further increases the contact area with the bottom surface of the beam plate 16, and also causes the outer edge of the anchoring base plate 8 to protrude outwards from the load-bearing pad 7. This allows one end of several dampers 6 to be connected to the periphery of the anchoring base plate 8. The other end of the dampers 6 is connected to the anchoring top plate 2.

[0038] In this embodiment, the anchoring top plate 2 is semi-circular and there are two of them, so that the two anchoring top plates 2 can be spliced ​​into a ring. Connecting lugs are provided at the splicing points of the two anchoring top plates 2, such as... Figure 5 As shown. After the two anchoring top plates 2 are spliced, their fixing ears are secured together with screws to connect them into a single unit. The hanger rod 1 passes between the two anchoring top plates 2. A limiting ring 17 is provided at the bottom of the hanger rod 1, and the outer diameter of the limiting ring 17 is larger than the diameter of the through hole formed by the two anchoring top plates 2. This allows the limiting ring 17 to support the anchoring top plate 2 and prevent it from falling. The base 3 is semi-circular and has two parts, so that the two bases 3 can be spliced ​​together to form a ring. The hanger rod 1 passes between the two bases 3. The connection structure of the two bases 3 is the same as the connection structure of the anchoring top plates 2, and it also has connecting ears. Similarly, the two base plates can be connected into a single unit using screws.

[0039] Both the anchoring top plate 2 and the bottom plate are designed as two spliced ​​pieces, allowing for replacement of either the anchoring top plate 2 or the bottom plate without removing the load-bearing pad 7 and the anchoring bottom plate 8 if either is damaged. The specific replacement method is as follows: First, remove the screws on the connecting lugs; then, separate and remove the two parts of the anchoring top plate 2 or the bottom plate. Bring the two parts of the new anchoring top plate 2 or the bottom plate close to the hanger 1 from both sides and splice them together, then connect the two parts with screws.

[0040] This invention also provides a vibration reduction and isolation system, including a vibration sensor 9, a controller 10, and the aforementioned boom anchoring device. The damper 6 is an adjustable hydraulic damper 6, which can be an HR series hydraulic damper 6. This series of hydraulic dampers 6 offers various cylinder diameters and configurations to choose from. Simultaneously, a speed adjustment knob 13 is provided at the end of the cylinder body furthest from the telescopic rod; the damping force can be adjusted by rotating the adjustment knob 13. Each damper 6 is equipped with a drive device. Both the drive device and the vibration sensor 9 are connected to the controller 10. The drive end of the drive device is connected to the damper 6.

[0041] In use, vibration sensor 9 is installed on beam 16 to monitor its vibration. The monitoring data from vibration sensor 9 is received and analyzed by controller 10. This analysis determines the optimal damping force required by several dampers 6. Controller 10 controls the drive unit, which in turn controls the rotation of adjustment knob 13, thereby ensuring that the damping force of each damper 6 reaches its optimal value. In this way, the dampers 6 operate in their optimal state, thus better controlling the vibration of beam 16.

[0042] In this embodiment, the driving device includes a drive motor 11 and an adjusting gear 12 connected to the drive motor 11. An adjusting knob 13 is provided at the tail of the damper 6. The adjusting knob 13 is equipped with adjusting teeth to engage with the adjusting gear 12. The drive motor 11 is connected to the controller 10. Existing adjusting knobs 13 generally do not have adjusting teeth. To ensure effective engagement between the adjusting gear 12 and the adjusting knob 13, adjusting teeth can be provided on the existing adjusting knob 13.

[0043] This embodiment also includes a solar panel 14 and a battery. The solar panel 14 is mounted on the suspension rod 1 and located on the upper surface of the beam plate 16. The battery is connected to the solar panel 14 and the controller 10. The solar panel 14 and the battery can provide power to the entire system.

[0044] This embodiment also includes a main controller 15. Several sets of suspension rod anchoring devices are provided, each set corresponding to one suspension rod 1. Several vibration sensors 9 and several controllers 10 are all connected to the main controller 15. The main controller 15 sends control signals to each controller 10 based on the monitoring data from the vibration sensors 9. The stress conditions of the bridge are relatively complex. By analyzing the vibration of the entire bridge deck through the main controller 15, a damping force adjustment scheme for several dampers 6 of each suspension rod anchoring device is formulated. This allows the entire bridge's roof to achieve better performance.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
