Bridge swivel system and mounting and swivel method thereof
The invention discloses a bridge swivel system and a mounting and swivel method thereof. A swivel device comprises an upper turntable arranged at the bottom of a bridge pier, an upper spherical hinge and a supporting leg which are arranged at the bottom of the upper turntable, a lower turntable and a slideway which are pre-buried at the top of a bearing platform, a lower spherical hinge arranged at the top of the lower turntable, and a positioning shaft arranged at the center of the lower spherical hinge; the upper spherical hinge and the lower spherical hinge serve as main supports and are in close fit, a sliding piece is arranged between the upper spherical hinge and the lower spherical hinge, and the upper rotary disc and the upper spherical hinge are positioned through a positioning shaft. The supporting leg and the slideway serve as assisted supports and are in sliding fit. The traction device comprises an anchor bearing and a prestress channel which are pre-buried on the upper turntable, a steel strand of which one end penetrates through the prestress channel and is connected with the anchor bearing, traction jacks connected with the other end of the steel strand, and a traction counter-force seat, a boosting counter-force seat and a limiting structure which are arranged at the top of the bearing platform; and the two groups of traction jacks and steel strands are reversely arranged on two sides of the upper turntable and can be controlled to be synchronous. The system is stable and safe in rotation, high in efficiency and capable of crossing two railway lines.
本发明公开了一种桥梁转体系统及其安装、转体方法，其中回转装置包括设在桥墩底部的上转盘、设在上转盘底部的上球铰和支腿、预埋在承台顶部的下转盘和滑道、设在下转盘顶部的下球铰、设在下球铰中心的定位轴，上球铰和下球铰作为主支撑贴紧配合且二者间设有滑片，上转盘和上球铰通过定位轴定位，支腿和滑道作为辅助支撑滑动配合，牵引装置包括预埋在上转盘上的锚座和预应力通道、一端穿过预应力通道与锚座连接的钢绞线、与钢绞线另一端连接的牵引千斤顶以及设在承台顶部的牵引反力座、助推反力座和限位结构，两组牵引千斤顶及钢绞线反向设在上转盘两侧且能在控制下同步。本发明回转平稳、安全、效率高，能跨越两条铁路线。
