Large-span normal-conducting high-speed magnetic levitation bridge parting structure
The invention relates to a large-span normal-conducting high-speed maglev bridge parting structure. The large-span normal-conducting high-speed maglev bridge parting structure comprises a large-span beam, a parting bearing beam, a cross large beam joint small beam, N parting small beams and a chain rod hinge system used for synchronously pushing the N parting small beams and the large-span beam to move in the same direction, wherein a first step part is arranged at the movable end of the large-span beam, a second step part is arranged at the fixed end of the parting bearing beam, and a fixed end and a movable end of the cross-girder seam small beam are arranged on the first step part and the second step part respectively; the N parting small beams are sequentially arranged on the horizontal plane of the second step part at intervals in the bridge direction and located between the vertical plane of the second step part and the cross girder seam small beam; the chain rod hinge system is arranged on the parting bearing beam, one end of the chain rod hinge system is connected with the movable end of the large-span beam, and the other end of the chain rod hinge system is connected with the N parting small beams. The structure is advantaged in that smoothness of the bridge floor can be improved, theoretically synchronous driving parting is achieved, the running comfort of the maglev train is improved, and safety and stability of high-speed running are improved.
本发明涉及一种大跨度常导高速磁浮桥梁分缝构造，包括大跨度梁、分缝承载梁、跨大梁缝小梁、N个分缝小梁以及用于同步推动N个分缝小梁与大跨度梁同向移动的链杆铰接系统；大跨度梁的活动端设有第一台阶部，分缝承载梁的固定端设有第二台阶部，跨大梁缝小梁的固定端和活动端分别设置于第一台阶部上和第二台阶部上；N个分缝小梁沿顺桥向依次间隔设置于第二台阶部的水平面上且位于第二台阶部的竖直面与跨大梁缝小梁之间；链杆铰接系统设置于分缝承载梁上，且其一端与大跨度梁的活动端连接，另一端分别与N个分缝小梁连接。本发明能够改善桥面的平顺性，事实实现理论上的同步驱动分缝，改善磁浮列车行驶舒适度，提高高速行车的安全稳定性。
