Precise in-position construction method for swivel bridge
The invention relates to the field of bridge construction equipment, in particular to a swivel bridge accurate in-position construction method, which is characterized in that an energy consumption bearing device is mounted at the beam end position of a swivel beam body, and the energy consumption bearing device is mounted at the head-on position of the swivel beam body in the swivel direction; the energy consumption bearing device is used for unloading the kinetic energy of the swivel beam body and converting the kinetic energy or part of the kinetic energy into power potential energy for storage, so that the rotation of the swivel beam body is slowly stopped through the energy consumption bearing device; rotation pushing is carried out on the rotation beam body so as to accurately adjust the position posture of the rotation beam body, and rotation pushing is achieved by combining external force and power potential energy stored by the energy consumption bearing device. The method has the advantages that the safety is high, redundant kinetic energy of the swivel beam is removed step by step through a plurality of devices in the stalling process, and the risks of beam body damage and structure overturning caused by forced stalling are greatly reduced; 2) the correction and rotation in position at the beam end position are more accurate and more effective, and 3) the phenomenon of inertial floating of the beam body caused by step-by-step adjustment at the beam end position is more controllable.
本发明涉及桥梁施工设备领域，尤其是一种转体桥精确就位施工方法，在转体梁体的梁端位置安装耗能承接装置，耗能承接装置安装在转体梁体转体方向的迎面位置；耗能承接装置对转体梁体的动能进行卸除并将该动能或部分该动能转换为动力势能储存，使转体梁体的转动通过耗能承接装置缓慢停转；对转体梁体进行回转顶推以精确调整其位置姿态，回转顶推是通过结合外力和耗能承接装置所储存的动力势能联合实现的。本发明的优点是：1）安全性高，停转过程中通过多个装置多次逐级卸除转体梁的多余动能，大大减少了强行停转造成的梁体损伤和结构倾覆的风险；2）在梁端位置修正转体就位更精确更有效；3）在梁端位置逐级调整造成的梁体惯性漂转的现象更可控。
