Description

Permanent integrated damper and vibration reduction system
Technical Field
The utility model relates to the field of vibration control of bridge engineering, in particular to a permanent integrated damper and a vibration reduction system.
Background
The stay cable is used as a main bearing member of the cable-stayed bridge, and is extremely easy to generate severe vibration under the external excitation of wind, wind and rain and the like due to the characteristics of low damping, large flexibility and light weight. Too much vibration of the stay cable not only causes fatigue damage of the stay cable, but also easily causes stress corrosion of an anchoring area. In addition, the stay cable vibrates by a wide margin, so that people and vehicles passing by can cause uncomfortable feeling and unsafe feeling, and the normal operation of the bridge is affected.
In the related art, because the stay cable needs to be debugged for many times during construction, the inclination angle of the stay cable and the main beam can be changed, if a conventional damper is installed at the stage, the initial position of the damper can deviate, and later adjustment is difficult. In order to eliminate adverse effects caused by large vibration of the stay cable in the construction process, a temporary vibration damping device is generally adopted in engineering to inhibit the vibration of the stay cable. The traditional vibration damping method mainly comprises a steel wire rope tensioning method and a cableway pipe plug wood wedge method.
The stretching wire rope method is to set one wire rope perpendicular to the length direction of the stay rope in the bridge deck to connect the stay rope with the main beam and to utilize the inner friction energy consumption of the wire rope to inhibit the vibration of the stay rope. However, the steel wire rope in the method of tensioning the steel wire rope has limited energy consumption capability, so that the vibration reduction effect is poor.
The cableway pipe plug wood wedge method is characterized in that a sharp wood wedge is arranged between the stay cable and the cableway pipe, so that the stay cable is tightly attached to the cableway pipe, vibration energy is consumed by utilizing the deformability of a wood block, and vibration of the stay cable is restrained. However, the wooden wedge has limited vibration damping effect, and when the wooden wedge transmits the vibration of the inhaul cable to the cableway pipe, the problem of fatigue of the cableway pipe can be caused.
Because the construction period of the large-span cable-stayed bridge is longer, if the two methods are adopted, the vibration reduction effect is limited, and the tensioning steel wire rope or the wooden wedge is required to be replaced frequently, so that the construction workload is increased. It is therefore important to design and install a suitable damping device for large span cable-stayed bridges.

And, the fastening assembly 8 includes a bolt and a nut screwed to each other.
Of course, in the third embodiment, the angle adjusting hole in the first connecting hole 403 may be a circular arc through hole with the positioning hole as the center, so that the angle adjusting range may be finer.
In some alternative embodiments, referring to fig. 1 and 3, the base 4 includes a base bottom plate 401 and a base side plate 402, and the base side plate 402 is disposed obliquely to the base bottom plate 401. Specifically, an embedded plate is laid on the bridge deck, the base bottom plate 401 is connected with the embedded plate, and the inclination direction of the base side plate 402 faces the direction of the stay cable so as to adapt to the initial inclination;
alternatively, the elongated first connection hole 403 of the embodiment is disposed parallel to the oblique direction of the base side plate 402.
In some alternative embodiments, referring to fig. 3, the mounting plate 7 includes a mounting plate base plate 701 and a mounting plate side plate 702, the second connection hole 703 is provided on the mounting plate side plate 702, and the damping assembly is mounted on the mounting plate base plate 701.
Specifically, as shown in fig. 3, the mounting plate side plate 702 is attached to the base side plate 402, so that the fastening assembly 8 is convenient to penetrate through the second connecting hole 703 and the first connecting hole 403;
and, the mounting plate bottom plate 701 and the mounting plate side plate 702 are perpendicular to each other, and the mounting plate bottom plate 701 is also disposed toward the inclination direction of the base side plate 402, thereby reducing the pressure of the damping assembly to the mounting plate 7.
In some alternative embodiments, see fig. 1, the damping assembly comprises a support 3, a damping device 5, a swinging rod 6 and a chain rod 9, wherein the support 3 and the damping device 5 are mounted on a mounting plate base plate 701, one end of the swinging rod 6 is connected with the damping device 5, and the other end is connected with the connecting rod 2; one end of the chain rod 9 is hinged with the swinging rod 6 through a first rotating shaft 10, and the other end of the chain rod is hinged with the support 3 through a second rotating shaft 11.
When the stay cable clamped by the cable clamp 1 connected with the connecting rod 2 vibrates, vibration is transmitted to the swinging rod 6 from the cable clamp 1 through the connecting rod 2, and the swinging rod 6 is hinged with the chain rod 9, so that the other end of the chain rod 9 is hinged with the support 3, and the two hinged parts can rotate, thereby avoiding poor vibration reduction effect caused by over-strong rigidity.
In addition, since the swing rod 6 is connected between the damping device 5 and the connecting rod 2, the connecting rod 2 transmits vibration to the swing rod 6 first, and then the swing rod 6 is transmitted to the damping device 5, a part of the vibration amount can be counteracted by the swing rod 6; the support 3 and the chain rod 9 play a supporting role on the damping device 5 and the swinging rod 6, and the swinging rod 6 and the support 3 are connected together through the chain rod 9, so that the damping effect is improved.
In some alternative embodiments, referring to fig. 1 and 5, the connecting rod 2 is a double-rod connecting rod, and the diameter of the end of the swinging rod 6 connected with the connecting rod 2 is larger than that of the end connected with the damping device 5, the end of the swinging rod 6 connected with the connecting rod 2 comprises a first end 601 and a second end 602, and the two rod bodies of the double-rod connecting rod are respectively connected with the first end 601 and the second end 602.
Specifically, the double-rod type connecting rod 2 increases the transverse bending rigidity of the connecting rod 2, and also can ensure the vibration damping effect.
In some alternative embodiments, as shown in figures 1, 4 and 5, the end of the support 3 remote from the mounting plate 7 is provided with an ear plate 301, the ear plate 301 being hinged to the chain bar 9 by means of a first pivot 10. Specifically, the lug plate 301 is arranged to hinge the chain rod 9 and the swinging rod 6 and hinge the chain rod 9 and the support 3, so that the vibration of the stay cable is favorably adapted.
In some alternative embodiments, see fig. 2, the connecting rod 2 is connected in rotation with the cable clamp 1, in particular by means of a third rotation shaft 12.
Specifically, as shown in fig. 8, when the center line of the stay cable is slightly shifted during construction, the cable Liang Jiao a is slightly changed, resulting in a change in the spatial coordinates of the installation point of the cable clamp 1. The cable clip 1 is now rotated about the third axis of rotation 12 to accommodate the change in cable Liang Jiao a (represented by a 1 Becomes a 2 ) The center line of the connecting rod 2 is deviated, so that the damper body has a certain stroke and can stretch out and draw back:
when the cable clamp 1 is provided with the installation position length x, the central line length (x.tana) of the connecting rod 2 is increased as the installation position length x of the cable clamp 1 is unchanged when the cable beam angle a is increased. When the cable Liang Jiao a is reduced, the attachment position length x of the cable clip 1 is unchanged, and the connecting rod center line length (x·tana) is reduced.
The telescopic travel here can accommodate small spatial coordinate variations of the mounting points of the cable clip 1, but is insufficient to accommodate large variations between the cable clip 1 and the damping assembly. So we choose to set the base 4 and the mounting plate 7 on the bottom of the damper, so that it can realize the adjustment of larger angle, thus adapting to the large space coordinate change of the stay cable clamp mounting point in the construction period.
The present utility model also provides a vibration damping system comprising:
the stay cable and the permanent integrated damper as described above, wherein the cable clamp 1 is connected with the stay cable to form a system, referring to fig. 8 specifically, when the center line of the stay cable changes, that is, the stay cable vibrates, or the position of the stay cable in the bridge construction process changes, on one hand, the stay cable can be pulled through the relative rotation between the cable clamp 1 and the connecting rod 2, and on the other hand, the relative position of the first connecting hole 403 and the second connecting hole 703 can be adjusted, so that the height of the damping device 5 is raised or lowered, or the orientation and angle of the damping device 5 are adjusted, so as to realize vibration reduction of the stay cable.
Therefore, the vibration reduction system provided by the embodiment of the utility model can effectively adapt to the position change between the cable clamp 1 and the damping component caused by cable adjustment, load test, bridge deck pavement and the like in the construction stage, and can also meet the target requirements of vibration suppression of the stay cable in the construction period and the operation period.
