Large-tonnage large-diameter integral swivel support mounting device and mounting method
The invention belongs to the technical field of bridge swivel supports, and particularly relates to a large-tonnage large-diameter integral swivel support mounting device and method. Comprising a rotating body lower disc, a rotating body upper disc and a rotating body support arranged between the rotating body lower disc and the rotating body upper disc, and a rotating system is further arranged between the lower end face of the rotating body upper disc and the lower end face of the rotating body lower disc. The rotating body lower disc and the rotating body upper disc are rotationally connected through a rotating body support; the swivel support comprises a lower spherical hinge fixed to the swivel lower disc and an upper spherical hinge fixed to the swivel upper disc, the upper spherical hinge and the lower spherical hinge are rotationally connected, and a limiting pin shaft is arranged in the center of the lower spherical hinge. Rotation of a large bridge can be achieved, it is guaranteed that traffic is not affected during construction, in addition, the supporting feet and the annular steel plate sliding ways can guarantee stress balance of the box girder in the rotation process and prevent inclination, the arranged pre-buried plate serves as an emergency rotation mechanism, and even if the upper spherical hinge and the lower spherical hinge are clamped and cannot rotate, the box girder can be prevented from inclining. And the rotation in place can be continuously realized by utilizing the pre-embedded plate.
本发明属于桥梁转体支座技术领域，具体涉及一种大吨位大直径整体式转体支座安装装置及安装方法。包括转体下盘，转体上盘，设于转体下盘和转体上盘之间的转体支座，转体上盘的下端面与转体下盘的下端面之间还设有转动系统；转体下盘与转体上盘之间通过转体支座转动连接；转体支座包括与转体下盘固定的下球铰，与转体上盘固定的上球铰，上球铰与下球铰之间转动连接，下球铰的中心处设有限位销轴。本发明可实现大型桥梁的转动，保证施工时不影响交通，此外本发明的撑脚和环形钢板滑道可保证转动过程箱梁的受力平衡，防止倾斜，设置的预埋板作为应急旋转机构，即使上球铰和下球铰之间卡住无法转动，也可利用预埋板继续实现转动到位。
