Ground anchor type suspension bridge rotary cable rotating saddle lower force transmission device and construction method
The invention provides a ground anchor type suspension bridge rotating cable rotating saddle lower force transmission device and a construction method.The force transmission device comprises an arc saddle body, an arc sliding pair, an arc stop block and a pushing limiting set, the arc saddle body is fixedly connected with a saddle head of a rotating cable saddle, and the arc sliding pair comprises an upper bearing plate, a sliding plate and a lower bearing plate which are arranged in an attached mode; the upper bearing plate and the sliding plate are arc-shaped plates, the surface, facing the sliding plate, of the lower bearing plate is an arc surface, the upper bearing plate is fixedly connected with the arc-shaped saddle body, and the lower bearing plate is anchored on the anchorage; the number of the arc-shaped check blocks is two, and the two arc-shaped check blocks are fixed to the ends of the two sides of the upper bearing plate in the longitudinal direction and abut against the two sides of the arc-shaped saddle body. The number of the pushing limiting sets is two, and the two pushing limiting sets are arranged at the upper end and the lower end of the lower bearing plate and movably abut against the upper end face and the lower end face of the upper bearing plate. According to the force transmission device, it can be guaranteed that the cable rotating saddle moves longitudinally and flexibly when the main cable is installed, meanwhile, damage to all components of the arc-shaped sliding pair is reduced, and the service life of the sliding pair is prolonged.
本发明提供一种地锚式悬索桥回转缆转索鞍鞍下传力装置及施工方法，传力装置包括弧形鞍体、弧形滑动副、弧形挡块和顶推限位组，弧形鞍体与转索鞍的鞍头固定连接，弧形滑动副包括相贴合设置的上承板、滑板和下承板，上承板和滑板均为弧形板，下承板朝向滑板的表面为弧面，上承板与弧形鞍体固定连接，下承板锚固在锚碇上；弧形挡块设置为两个，两个弧形挡块沿纵向固定在上承板的两侧端部，并抵接于弧形鞍体的两侧；顶推限位组设置为两个，两个顶推限位组设置在下承板的上下两端部，并可活动地抵接于上承板的上下两端面。本发明的传力装置，可以保证主缆安装时转索鞍纵向灵活移动，同时也减小对弧形滑动副各个构件的损坏，延长滑动副的使用寿命。
