Metal friction damper with self-resetting function and anti-seismic bridge
The invention relates to the technical field of dampers, in particular to a metal friction damper with a self-resetting function and an anti-seismic bridge. The metal friction damper comprises two cantilevers, one ends of the two cantilevers are jointly connected with a load control rod, the other ends of the two cantilevers are rotationally connected with a rotating shaft, the left side and the right side of each cantilever are each provided with an outer connecting plate, and the outer connecting plates are slidably connected with the rotating shaft; the inner sides of the outer connecting plates are fixedly connected with metal friction curved surface outer wheels, the left side and the right side of the cantilever are each fixedly connected with a metal friction curved surface inner wheel, and the metal friction curved surface inner wheels and the metal friction curved surface outer wheels can drive the outer connecting plates to be close to or away from each other when rotating relatively. The load control rod can drive the metal friction curved surface inner wheel and the metal friction curved surface outer wheel to rotate relatively, and the outer connecting plate is connected with a spring set used for enabling the two outer plates to be close to each other. Compared with a damper in the prior art, on one hand, the overall structure is more compact, and on the other hand, the friction area is increased.
本发明涉及阻尼器技术领域，具体是一种具有自复位功能的金属摩擦阻尼器及抗震桥梁，包括2个悬臂，2个悬臂的一端共同连接有载荷控制杆，另一端转动连接有转轴，悬臂的左右两侧各设有1个外连接板，外连接板与转轴滑动连接，外连接板的内侧固定连接有金属摩擦曲面外轮，悬臂左右两侧各固定连接有1个金属摩擦曲面内轮，金属摩擦曲面内轮和金属摩擦曲面外轮相对转动时可带动外连接板相互靠近或远离，载荷控制杆能够带动金属摩擦曲面内轮和金属摩擦曲面外轮相对转动，外连接板连接有用于使2个外板相互靠近的弹簧组；本发明相对于现有技术中的阻尼器，一方面整体结构更加紧凑，另一方面增大了摩擦面积。
