Anti-sliding cable saddle of suspension bridge
The invention discloses an anti-slip cable saddle of a suspension bridge, and relates to the technical field of suspension bridge structures, the cable saddle comprises a bottom plate arranged on the top of a tower column; the supporting mechanism is arranged on the bottom plate; the two saddle grooves are both formed in the supporting mechanism, each saddle groove comprises a separation section and extension sections connected to the two ends of the separation section, the extension sections are bent towards the bottom plate, the two ends of the separation sections in the two saddle grooves are correspondingly connected, the middles of the separation sections in the two saddle grooves protrude towards the direction away from each other, and the ends and the middles of the separation sections are in smooth transition. The main cable is in contact with the side wall of the middle protruding part in the direction away from each other, and the friction force between the main cable and the saddle groove is increased. The saddle groove comprises the separation section and the extension sections connected to the two ends of the separation section, the extension sections are bent towards the bottom plate, the wrap angle of the cable saddle is increased, and the friction force between the main cable and the saddle groove is improved. The problems that in the prior art, the friction force is increased in a limited mode or durability and reliability are not high due to the fact that the friction force is increased by adding a zinc layer or tensioning a high-strength screw rod are solved.
本发明公开了一种悬索桥抗滑型索鞍，涉及悬索桥结构技术领域，该索鞍包括：底板，其用于设置在塔柱顶部；支撑机构，其设置在底板上；两个鞍槽，均设置在支撑机构上，鞍槽包括分离段和连接在分离段两端的延长段，延长段朝底板方向弯曲，两个鞍槽中分离段的两端对应连接，中部向相互远离的方向凸起，且分离段的端部与中部平滑过渡。主缆与中部向相互远离的方向凸起部分的侧壁接触，增加了主缆与鞍槽之间的摩擦力。鞍槽包括分离段和连接在分离段两端的延长段，延长段朝底板方向弯曲，增加了索鞍的包角，提高了主缆与鞍槽之间的摩擦力。解决了现有技术中采用增加锌层或张拉高强螺杆增加摩擦力，存在摩擦力提高有限或耐用性可靠度不高的问题。
