Bridge swivel spherical hinge with anti-pulling function
The invention discloses a bridge swivel spherical hinge with an anti-pulling function. The bridge swivel spherical hinge comprises an upper spherical hinge body, a lower spherical hinge body, an anti-pulling shaft and annular anti-pulling ribs. The upper spherical hinge comprises a low-roughness convex spherical panel, a middle anti-pulling sleeve is arranged in the center of the low-roughness convex spherical panel, and the middle anti-pulling sleeve comprises an upper sleeve, a conical sleeve and an upper anti-pulling plate welded to the large-caliber end of the conical sleeve; the lower spherical hinge comprises a concave spherical panel, a threaded sleeve is arranged in the center of the concave spherical panel, and a lower anti-pulling plate is fixed to the end, away from the upper spherical hinge, of the threaded sleeve; the concave spherical panel is provided with a plurality of coaxially arranged annular troughs, and sliding plates are embedded in the annular troughs; the upper spherical hinge and the lower spherical hinge are restrained in the horizontal direction and the vertical direction, the risk of overturning caused by unbalanced moment generated by a bridge is avoided, and the spherical hinge is particularly suitable for asymmetric swivel bridge structures such as a curved bridge and a variable-cross-section bridge. The safety of bridge swivel construction is improved; an annular sliding plate structure is further adopted, and machining and manufacturing of the spherical hinge are facilitated.
本发明公开了一种具有抗拔功能的桥梁转体球铰，包括上球铰、下球铰、抗拔轴与环向抗拔筋；所述上球铰包括低粗糙凸球面板，低粗糙凸球面板的中心处设置有中间抗拔套，中间抗拔套包括上套筒、锥形套筒与焊接在锥形套筒大口径一端的上抗拔板；所述下球铰包括凹球面板，凹球面板的中心处设置有螺纹套管，螺纹套管远离上球铰的一端上固定有下抗拔板；所述凹球面板上设置有若干同轴设置的环形槽，环形槽内镶嵌设置有滑板，本发明中将上、下球铰在水平及竖向进行了约束，避免桥梁产生不平衡力矩导致倾覆的风险，特别适用曲线桥梁、变截面桥梁等非对称转体桥梁结构，提高了桥梁转体施工的安全性；本发明还采用环形滑板结构，便于球铰加工制作。
