Controllable overturn-preventing swivel spherical hinge
The invention discloses a controllable overturn-preventing swivel spherical hinge. The controllable overturn-preventing swivel spherical hinge comprises a spherical hinge bracket, a lower spherical hinge, a limiting pin shaft and an upper spherical hinge, wherein the lower spherical hinge is fixed on the spherical hinge bracket; the upper spherical hinge is coaxially and longitudinally overlappedabove the lower spherical hinge; the upper spherical hinge and the lower spherical hinge are assembled in a spherical rotating mode; the limiting pin shaft is fixed to the center of the lower spherical hinge; a limiting hole allowing the limiting pin shaft to be inserted therein is formed in the upper spherical hinge; the limiting pin shaft is of a concrete-filled steel tube structure; the upper spherical hinge is of an annular convex spherical structure; and the lower spherical hinge is of an annular concave spherical structure matched with the upper spherical hinge. Compared with the prior art, the upper spherical hinge and the lower spherical hinge are integrally arranged to form a hollow circular ring shape, so a narrower cross section can be achieved under the condition of the same bearing capacity, and the compactness degree of bottom concrete pouring is better guaranteed; the whole plane structure of the controllable overturn-preventing swivel spherical hinge is annular, backfilling and sealing of a center part after swivel operation is completed are facilitated, and safe use of a bridge in a later period is guaranteed.
本发明公开了一种可控式防倾覆转体球铰，包括球铰支架、下球铰、限位销轴和上球铰。其中，下球铰固定于球铰支架上，上球铰同轴纵向叠置于下球铰上方，上球铰与下球铰呈球面转动装配，限位销轴固定于下球铰的中心位置，上球铰上设有供限位销轴插入的限位孔，限位销轴为钢管混凝土结构，上球铰呈圆环形凸球面结构，下球铰呈与上球铰适配的圆环形凹球面结构。相比于现有技术，本发明的上球铰和下球铰整体呈中空的圆环形设置，同等承载力情况下可以实现横断面更窄，更利于保证其底部混凝土浇筑的密实程度；可控式防倾覆转体球铰整体平面结构为环形，有利于转体作业完成后对中心部位的回填封固，确保后期桥梁安全使用。
