Displacement amplifying device
When the displacement amplifying device is used, an upper hinge lug seat is connected with an upper structure such as an upper bridge or a building, a lower hinge lug seat is connected with a lower structure such as a lower bridge or the building, a first hinge position of a hinge rod assembly is hinged to the upper hinge lug seat, and a second hinge position of the hinge rod assembly is hinged to the lower hinge lug seat. The third hinge position is hinged to the damper, so that the whole mechanism forms a lever structure with the second hinge position as the center point, and the hinge rod assembly swings with the second hinge position as the center during an earthquake; the vertical distance between the first hinge position and the second hinge position is smaller than that between the second hinge position and the third hinge position, so that the swing amplitude of the third hinge position is larger than that of the first hinge position, and the effect of amplifying the displacement of the damper is achieved; therefore, consumption of earthquake energy by the damper can be enhanced, and the working efficiency and the fatigue performance of the damper can be improved when an earthquake occurs.
本发明公开了一种位移放大装置，在使用时通过上铰接耳座与上部桥梁或建筑等上部结构连接，下铰接耳座与下部桥梁或建筑等下部结构连接，而铰接杆组件的第一铰接位置与上铰接耳座铰接，第二铰接位置与下铰接耳座铰接，第三铰接位置与阻尼器铰接，从而使得机构整体形成以第二铰接位置为中心点的杠杆结构，地震时铰接杆组件以第二铰接位置为中心进行摆动，而由于第一铰接位置和第二铰接位置之间的竖直距离小于第二铰接位置与第三铰接位置之间的竖直距离，因此第三铰接位置的摆动幅度会大于第一铰接位置的摆动幅度，从而起到放大阻尼器位移的效果，从而可以增强阻尼器对地震能量的消耗，在地震发生时可提高阻尼器的工作效率和提高阻尼器的疲劳性能。
