Bridge vortex vibration control device
The invention relates to the field of bridge engineering. The invention particularly discloses a bridge vortex vibration control device. The device comprises a control unit arranged at the bottom of abridge; the control unit comprises a plurality of controllers; the controller comprises a base and a plurality of sliding sheets; a sliding groove is formed in the base in the length direction; a wedge block is arranged in the sliding groove in a sliding mode; a plurality of sliding holes are formed in the two sides of the base; the sliding sheet is arranged in the sliding hole; a wedge surface matched with the wedge block is arranged at the end part of the sliding sheet; a wind shielding structure is arranged at the bottom of the sliding sheet; the wind shielding structure comprises a firstconnecting rod, a second connecting rod, a third connecting rod and a wind shielding curtain; the first connecting rod and the second connecting rod are hinged to the bottom of the sliding piece, thetwo ends of the third connecting rod are hinged to the first connecting rod and the second connecting rod respectively, the wind shielding curtain is quadrilateral, and three sides of the wind shielding curtain are arranged on the first connecting rod, the second connecting rod and the third connecting rod respectively. The technical problem that vortex vibration possibly occurs to a bridge underthe condition of low wind speed can be solved.
本发明涉及桥梁工程领域，具体公开了桥梁涡振控制装置，包括设置在桥梁底部的控制单元，所述控制单元包括若干控制器，所述控制器包括底座和若干滑动片，所述底座上沿长度方向开设有滑槽，所述滑槽内滑动设有楔块，所述底座的两侧设有若干滑孔，滑动片设置在滑孔内，滑动片的端部设有与楔块配合的楔面，滑动片的底部设有挡风结构，所述挡风结构包括第一连杆、第二连杆、第三连杆以及挡风帘，所述第一连杆和第二连杆均与滑动片底部铰接，第三连杆的两端分别与第一连杆和第二连杆铰接，所述挡风帘呈四边形且其三边分别设置在第一连杆、第二连杆和第三连杆上。本发明的目的在于解决桥梁在低风速情况下可能出现涡振的技术问题。
