Roll shaft type cable saddle with characteristics of main cable saddle and splay cable saddle and using method thereof
The invention relates to a roll shaft type cable saddle with characteristics of a main cable saddle and a splay cable saddle and a using method thereof. The cable saddle comprises a mid-span side half cable saddle and an anchor-span side half cable saddle which are connected with each other, the side walls of saddle grooves of the mid-span side half cable saddle are parallel to each other, and a main cable is supported and steered; the side wall of a saddle groove of the anchor-span side half cable saddle gradually expands outwards in the anchorage direction, is an arc-shaped conical surface structure and supports, steers and diverges the main cable; and the mid-span side half cable saddle and the anchor-span side half cable saddle are arranged on the base, the base is arranged on the upper bearing plate, a rolling friction pair is arranged between the upper bearing plate and the lower bearing plate, and pre-deflection of the cable saddle is achieved through rolling of the rolling friction pair. The cable saddle is simple in structure, reasonable in stress diffusion, complete in function and convenient to install and maintain, and therefore a tower-free ground anchor type suspension bridge which is small in excavation volume, short in construction period, considerable in economic benefit and environmentally friendly can be built in steep mountainous areas and canyons.
本发明涉及一种具有主索鞍及散索鞍特性的辊轴式索鞍及其使用方法，索鞍包括彼此连接的中跨侧半索鞍和锚跨侧半索鞍，中跨侧半索鞍的鞍槽侧壁相互平行，对主缆进行支承和转向；锚跨侧半索鞍的鞍槽侧壁向锚碇方向逐渐外扩，呈弧形锥面结构，对主缆进行支承、转向和发散；中跨侧半索鞍和锚跨侧半索鞍设于底座上，底座设于上承板上，上承板和下承板之间设有滚动摩擦副，通过滚动摩擦副的滚动实现索鞍的预偏。本发明构造简单、应力扩散合理、功能完善、安装维护方便，从而使得在陡峭山区峡谷中修建开挖量少、施工工期短、经济效益可观和环境友好的无塔地锚式悬索桥成为可能。
