Swing type seismic mitigation and isolation cable saddle
The invention discloses a swing type seismic mitigation and isolation cable saddle which comprises a saddle body and a base, a mounting groove is formed in the base, the saddle body is arranged in the mounting groove, a lubricating structure is arranged between the bottom face of the saddle body and the mounting groove, and gaps for prolonging the natural vibration period of the saddle body are formed between the saddle body and bosses at the two ends of the mounting groove. The saddle body is further connected with the bosses at the two ends of the mounting groove through pre-tightening structures, and the contact face between the lubricating structure and the mounting groove is a swing face of an arc-shaped structure. The saddle body and the base are connected through the pre-tightening structure, when a strong earthquake occurs, the pre-tightening structure is damaged firstly, the saddle body and the base are separated, the saddle body swings and slides along the mounting groove under the action of earthquake energy absorbed by the main cable, part of the earthquake energy is consumed, the impact of the earthquake energy on the main tower is reduced, and the construction cost of the main tower is effectively reduced; meanwhile, the safety of the suspension bridge is facilitated.
本发明公开了一种摆动式减隔震索鞍，包括鞍体以及底座，底座上开设有安装槽，鞍体设置在安装槽内，鞍体的底面与安装槽之间设置有润滑结构，且鞍体与安装槽两端的凸台之间具有延长鞍体自振周期的间隙，鞍体还通过预紧结构与安装槽两端的凸台连接在一起，润滑结构与安装槽之间的接触面为弧形结构的摆动面。本发明鞍体与底座通过预紧结构连接，而在发生较强地震时，预紧结构先被破坏，使鞍体与底座分开，鞍体在主缆吸收的地震能量的作用下沿着安装槽进行摆动滑移，消耗部分地震能量，减少地震能量对主塔的冲击，有效降低主塔的建设成本，同时有利于悬索桥的安全。
