Over-rotation prevention system and method for swivel bridge construction
The invention relates to an over-rotation prevention system and method for swivel bridge construction, and the system comprises an annular slide way fixed on a concrete lower turntable, and further comprises a fixed limiting device and a movable limiting device which is matched with the fixed limiting device for use so as to carry out over-rotation prevention limiting on a supporting leg fixed on a swivel upper disc; in the rotating process of the rotating body upper disc, the movable limiting device is pushed by the supporting feet and rotates above the annular sliding way along the circle center of the annular rail. During limiting, the movable limiting device is pushed by the supporting feet and finally abuts against the fixed limiting device. During abutting, the movable limiting device buffers and consumes the kinetic energy of the supporting feet and the swivel bridge and reduces the impact load. According to the system, the over-rotation problem occurring in the swivel bridge construction process can be effectively prevented, the buffering material and the buffering device are adopted at the collision position, the effects of buffering and reducing the collision force are achieved, and the bridge pier or the supporting foot is prevented from being collided and damaged.
本申请涉及一种用于转体桥施工的防过转系统及方法，包括固定在混凝土下转盘上的环形滑道，还包括固定限位装置和与固定限位装置配合使用以对固定在转体上盘上的撑脚进行防过转限位的活动限位装置；在转体上盘转动的过程中，所述活动限位装置由撑脚推动并在环形滑道上方沿环形轨道的圆心转动；在限位时，所述活动限位装置被撑脚推动并最终抵靠在固定限位装置上；抵靠时，活动限位装置对撑脚及转体桥的动能进行缓冲消耗及减小冲击荷载。本申请的系统能够有效防止转体桥施工过程出现的过转问题，通过在碰撞位置采用缓冲材料及缓冲装置，起到了缓冲和减小碰撞力的作用，防止桥墩或者撑脚发生碰撞破坏。
