Over-rotation prevention method for swivel bridge construction
The invention relates to an over-rotation prevention method for swivel bridge construction, in the method, when a swivel upper disc rotates to a preset position, a supporting foot pushes a movable limiting device to abut against a fixed limiting device, and over-rotation prevention of swivel bridge construction is achieved; meanwhile, in the abutting process, the movable limiting device and the fixed limiting device buffer and consume kinetic energy of the supporting feet and the swivel bridge, and impact loads are reduced. According to the over-rotation preventing system used in the over-rotation preventing method for swivel bridge construction, the over-rotation problem occurring in the swivel bridge construction process can be effectively prevented. Buffering materials and buffering devices are adopted at the collision positions, the effects of buffering and reducing collision force are achieved, and the bridge pier or the supporting feet are prevented from being collided and damaged. And the slope groove is formed in the rail groove and used for preventing the movable limiting device from rebounding, so that the aim of accurately positioning the rotating body is achieved, and the subsequent fine adjustment time is saved.
本申请涉及一种用于转体桥施工的防过转方法，方法中，当转体上盘转动到预定的位置时，撑脚推动活动限位装置抵靠在固定限位装置上，实现转体桥施工的防过转；同时，抵靠过程中活动限位装置和固定限位装置对撑脚及转体桥的动能进行缓冲消耗并减小冲击荷载。本申请的用于转体桥施工的防过转方法中使用的防过转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。在轨道槽内设置斜坡槽用来阻止活动限位装置的回弹，进而达到转体精准就位的目的，节约了后续微调的时间。
