The invention relates to the technical field of bridge construction, in particular to a swivel system crossing a railway bridge. The system is characterized by comprising a spherical hinge lower support arranged on the ground, a rotating body spherical hinge arranged on the spherical hinge support, a spherical hinge upper support arranged on the rotating body spherical hinge, a rotating body bridge arranged on the spherical hinge upper support and a balance weight balancing device arranged below the rotating body bridge; wherein the spherical hinge upper support is located on one side of the center of the swivel bridge, the swivel bridge comprises a long bridge body and a short bridge body, the balance weight balancing device is arranged below the short bridge body, and the balance weightbalancing device is used for keeping the long bridge body and the short bridge body balanced. The balance weight balancing device arranged below the short bridge body can balance the moment of force at the two ends of the swivel spherical hinge, so that the tensile stress on the swivel bridge is uniformly distributed, and the swivel bridge is uniformly deformed.
本申请涉及桥梁建设的领技术域，尤其是涉及一种跨铁路桥的转体系统，其特征在于：包括设置在地面上的球铰下支座、设置在球铰支座上的转体球铰、设置在转体球铰上的球铰上支座、设置在球铰上支座上的转体桥梁以及设置在转体桥梁下方的配重平衡装置；所述球铰上支座位于转体桥梁中心的一侧，所述转体桥梁包括长桥体以及短桥体，所述配重平衡装置设置在短桥体的下方，所述配重平衡装置用于使长桥体和短桥体保持平衡。本申请具有在短桥体下方设置的配重平衡装置可以使转体球铰两端的力矩平衡，使转体桥梁上的拉应力分布均匀，使转体桥梁均匀变形的效果。
