Bridge stay cable damping mechanism
The invention discloses a bridge stay cable damping mechanism, and belongs to the technical field of bridge engineering, the bridge stay cable damping mechanism comprises a bottom plate mounted on a bridge floor and a mounting frame mounted on a stay cable, and a connecting assembly is mounted between the bottom plate and the mounting frame; the connecting assembly comprises a first connecting rod in spherical hinge connection with the bottom plate and a second connecting rod in spherical hinge connection with the mounting frame, the ends, close to each other, of the first connecting rod and the second connecting rod are in spherical hinge connection with connecting plates, a damper is arranged at the spherical hinge joint, and the two connecting plates are connected through a first spring; buffering fixing bases are elastically connected to the two sides of the mounting frame and mounted on the stay cable. When the stay cable vibrates, the mounting frame is driven to move, the first connecting rod and the second connecting rod rotate through the spherical hinge connecting part, the first spring between the two connecting plates deforms to achieve buffering, and through damping vibration absorption of the spherical hinge connecting part, when the stay cable vibrates in any direction, damping vibration absorption is achieved. Buffering and vibration absorption can be carried out through the connecting assembly.
本发明公开了一种桥梁斜拉索减震机构，属于桥梁工程技术领域，包括：安装在桥面上的底板以及安装在斜拉索上的安装架，底板与安装架之间安装有连接组件，连接组件包括与底板球铰连接的第一连接杆以及与安装架球铰连接的第二连接杆，第一连接杆与第二连接杆相靠近的一端均球铰连接有连接板，球铰连接处设有阻尼，两个连接板之间通过第一弹簧连接，安装架两侧均弹性连接有缓冲固定座，缓冲固定座安装在斜拉索上。本发明当斜拉索发生振动时，带动安装架运动，第一连接杆以及第二连接杆通过球铰连接部位转动，使两个连接板之间的第一弹簧变形实现缓冲，并通过球铰连接部位的阻尼吸振，实现了斜拉索任意方向振动时，能通过连接组件进行缓冲和吸振。
