In recent years, in bridge construction, large span stayed-cable bridge is used widely, and the vibration problem of thing followed suspension cable is also outstanding day by day.Main Inclined Cable Vibration control mode is that composed of external damping device carries out vibration isolation at present, and has had various types of dampers to be successfully applied on the drag-line of cable stayed bridge.The direction of the vibration isolation that common single damper can play is single, mostly be chain of command internal vibration, but the direction of vibration of suspension cable has randomness, damper not the vibration of active direction will can not get controlling, and these vibrations can impact the use of drag-line and full-bridge equally.
For the vibration isolation outside suspension cable face, the modes that two dampers are installed that adopt are controlled more at present, and this will cause the waste of damping unit, is not clearly for the vibration isolation effect of some direction simultaneously.Also having a kind of mode is to adopt mechanical device that out-of-plane vibration is reached to a damper, and this mode can only adopt a damper, has avoided the waste of damping unit, but plays control action with the vibration in the plane vertical with this face in same opposite.For two existing problems a kind of can save damping unit again can to suspension cable directive vibration rise control action vibration control system be badly in need of research and development.
Utility model content
Technical problem to be solved in the utility model is that a kind of comprehensive Inclined Cable Vibration control system will be provided, and it only needs a conventional damper, can play good control to the vibration of suspension cable all directions again simultaneously.
For solving above technical problem, the utility model provides a kind of comprehensive Inclined Cable Vibration control system, comprise control system arc-shaped slide rail base, control system inhaul cable vibration guide rail, be filled in the high-damping rubber piece on control system arc-shaped slide rail base, conventional suspension cable damper and suspension cable, by the support connection control system inhaul cable vibration guide rail on this arc-shaped slide rail base, this arc-shaped slide rail base two pick up the ears and inhaul cable vibration guide rail between fill high-damping rubber, conventional damper is installed on inhaul cable vibration guide rail, conventional damper is connected with suspension cable.
Described control system arc-shaped slide rail base, is to be picked up the ears by the welding of band base plate circular arc slide rail, and the formation of bolt drag-line rail brackets.Described circular arc slide rail base plate arranges bolt hole, be connected with bridge floor by high-strength bolt, two pick up the ears and inhaul cable vibration guide rail between fill high-damping rubber piece, the latch by support connects inhaul cable vibration guide rail.
Described control system inhaul cable vibration guide rail, by Plate Welding or the cuboid framework that is cast into, one end that inhaul cable vibration guide rail is connected with arc-shaped slide rail arranges with arc-shaped slide rail with wide semicircle sliding-tongue, top utilizes bolt to be connected on two perpendicular walls on one side, is welding square steel with holes with the same At The Height of support latch of arc-shaped slide rail base.Sliding-tongue ensures that inhaul cable vibration guide rail is all the time at setting rotation with in surface, and square steel with holes is for connection control system arc-shaped slide rail base, and middle cavity is used for installing conventional suspension cable damper and suspension cable.Described control system inhaul cable vibration guide rail, upper end is for can load and unload cover plate, and lower end is semicircle cylindricality sliding-tongue, welds square steel with holes, is fixed on arc-shaped slide rail base by square steel with holes.
The high-damping rubber piece of described control system base, be placed on that two of arc-shaped slide rail base pick up the ears and inhaul cable vibration guide rail between.
Described conventional suspension cable damper, is bolted on inhaul cable vibration guide rail cavity base, and the other end is connected with suspension cable.
Compared with prior art, superior effect of the present utility model:
1) vibration in all directions can reach bottom by drag-line to utilize lever principle, by bottom high-damping rubber piece, vibrational energy is dissipated, conventional damper is arranged on drag-line guide rail simultaneously, can ensure in the moment drag-line along lead rail axis to vibration controlled;
2) the utility model can only just can be controlled the vibration of all directions with a conventional damper, and not only just in plane vibration and the vibration perpendicular to this face;
3) the utility model can effectively reduce the size of base by controlling the height of support, meets aesthetic design;
4) material that the utility model uses is common steel, easily obtains, and does not need special materials processing, and manufacturing process is simple;
5) the utility model operating principle is simple, and how with bolts the connection between member is, and Component composition is convenient, is convenient to install;
6) the utility model has overcome existing out-of-plane vibration control method and the limited shortcoming of control device control direction of vibration;
7) its out-of-plane vibration of the utility model mainly provides damping by high-damping rubber piece, and its in plane vibration is mainly provided by the conventional damper being arranged on inhaul cable vibration guide rail, and the division of labor is clear and definite.
