Self-resetting variable damping shearing type lead damper
The self-resetting variable damping shearing type lead damper comprises a sleeve shearing cylinder which is connected in a sleeved mode, and a sleeve comprises an outer cylinder and an inner cylinder which is coaxially connected into the outer cylinder in a sleeved mode; the shearing cylinder is connected to the open end of the outer cylinder in a sleeved mode, the outer cylinder comprises an outer cylinder body and an outer end plate installed at one end of the outer cylinder body, and one end of the inner cylinder is connected with the outer end plate. A first shearing groove is formed in the outer cylinder, a second shearing groove is formed in the shearing cylinder, a third shearing groove is formed in the inner cylinder, and a fourth shearing groove is formed in the limiting block; outer lead rings are arranged in the first shearing groove and the second shearing groove, and inner lead rings are arranged in the third shearing groove and the fourth shearing groove; when the lead shearing type damper is subjected to seismic oscillation, the sleeve firstly drives the inner lead ring to perform shearing motion, and when the displacement is too large, the outer lead ring is driven to perform shearing motion at the same time, so that the application range of the lead shearing type damper is widened. The good reset capacity is achieved through the reset spring, and the capacity of residual displacement on the damper for resisting the next earthquake is reduced.
本发明公开了一种自复位变阻尼剪切型铅阻尼器，包括套接的套筒剪切筒，所述的套筒包括外筒和同轴套接在外筒内的内筒；剪切筒套接在外筒开口的一端，外筒包括外筒体和安装在外筒体一端的外端板，所述的内筒的一端与外端板连接；外筒体开设有第一剪切槽，剪切筒体开设有第二剪切槽，内筒开设有第三剪切槽，限位块朝开设有第四剪切槽；第一剪切槽与第二剪切槽内布置有外铅环，第三剪切槽与第四剪切槽内布置有内铅环；本发明在受到地震动时，套筒首先带动内铅环发生剪切运动，当位移过大时则带动外铅环同时发生剪切运动，提高了铅剪切型阻尼器的使用范围。通过复位弹簧实现了良好的复位能力，减小残余位移对阻尼器抵御下次地震的来临时的能力。
