Shock absorption and isolation cable saddle
The invention discloses a seismic mitigation and isolation cable saddle which comprises a saddle body used for fixing a main cable; the base is connected with the main tower; wherein 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, buffering energy dissipation pieces are arranged between the saddle body and bosses at the two ends of the mounting groove, one end of each buffering energy dissipation piece makes contact with the corresponding boss, and a gap for prolonging the natural vibration period of the saddle body is formed between the other end of each buffering energy dissipation piece and the saddle body. The saddle body is further connected with the bosses at the two ends of the installation groove through pre-tightening structures. When an earthquake occurs, the pre-tightening structure is damaged firstly, the saddle body is separated from the base, the saddle body slides automatically firstly, earthquake energy is separated from the main tower, part of the earthquake energy is consumed, when the earthquake energy is enhanced, the saddle body makes contact with the buffering energy dissipation piece, part of the earthquake energy is absorbed by the buffering energy dissipation piece, and the earthquake energy transmitted to the main tower is reduced; the construction cost of the main tower is effectively reduced, and the safety of the suspension bridge is facilitated.
本发明公开了一种减隔震索鞍，包括：鞍体，鞍体用于固定主缆；底座，底座与主塔连接；其中，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设置有缓冲耗能件，缓冲耗能件的一端与凸台接触，另一端与鞍体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。本发明中，发生地震时，预紧结构先被破坏，鞍体与底座分开，鞍体首先进行自滑移，将地震能量与主塔隔开并消耗部分地震能量，而在地震能量增强时，鞍体与缓冲耗能件接触，缓冲耗能件吸收部分地震能量，减少向主塔传递的地震能量，有效降低主塔的建设成本，有利于悬索桥的安全。
