Lever amplification damping device and bridge system
The invention relates to a lever amplification damping device which comprises a sliding rail, a speed locker, a connecting rod and a lever amplification damper, and the sliding rail is used for being fixed to a main beam; one end of the speed locker is slidably installed on the sliding rail, and the other end of the speed locker is used for being fixed to the main beam. One end of the connecting rod is hinged to the end, slidably installed on the sliding rail, of the speed locker. The lever amplification damper is movably connected with the other end of the connecting rod and used for being hinged to the main tower. The speed locker and the connecting rod are both installed on the sliding rail in a sliding mode, so that displacement generated by the main beam under the temperature load effect is freely stretched out and drawn back through reciprocating movement of the speed locker on the sliding rail, and the other end of the connecting rod is movably connected with the lever amplification damper. The vertical vortex-induced vibration generated by the main beam under the wind load is conducted to the lever amplification damper through the connecting rod, bridge vibration is restrained, and the technical problem that in the prior art, the main beam cannot freely stretch out and draw back under the effect of the temperature load, and harmful structural stress is generated is solved.
本申请涉及一种杠杆放大阻尼装置，其包括：滑轨、速度锁定器、连接杆和杠杆放大阻尼器，滑轨用于固定于主梁；速度锁定器的一端滑动安装于滑轨，速度锁定器的另一端用于固定于主梁；连接杆的一端与速度锁定器滑动安装于滑轨的一端铰接；杠杆放大阻尼器与连接杆的另一端活动连接，杠杆放大阻尼器用于铰接于主塔。通过将速度锁定器和连接杆均滑动安装于滑轨，使主梁在温度荷载作用下产生的位移通过速度锁定器在滑轨往复移动得到自由伸缩，连接杆的另一端活动连接杠杆放大阻尼器，使主梁在风荷载下产生的竖向涡激振动通过连接杆传导至杠杆放大阻尼器，抑制桥梁振动，解决了相关技术中主梁在温度荷载作用下无法自由伸缩，产生有害结构应力的技术问题。
