The invention relates to the technical field of bridges, in particular to a bridge damping device. The device comprises a pier and a bridge floor connected to the top of the pier through a bridge, thebridge is of a Y-shaped concrete structure, and first damping mechanisms are arranged at the top of the bridge in a bilateral symmetry manner. Each first damping mechanism comprises a top frame fixedly connected to the top of the bridge and a concave frame located at the outer side of the top of the top frame, supporting tables are arranged in the middles of the top frames, first springs are fixedly connected between the upper sides of the supporting tables and the inner walls of the bottom sides of the concave frames, buffer grooves are formed in the inner side walls of the tops of the concave frames, and the top ends of the top frames are inserted into the buffer grooves. Longitudinal shock absorption is effectively conducted on the bridge floor through the first springs, meanwhile, thebridge floor is connected with a supporting concave seat through rubber supports, first steel plates and polytetrafluoroethylene plates can relatively slide, so that shock absorption is effectively conducted on the bridge floor in the horizontal direction, rapid resetting of the bridge floor is facilitated, and longitudinal pressure borne by the bridge floor can be buffered; and then shock absorption in the longitudinal and horizontal directions is achieved.
本发明涉及桥梁技术领域，具体涉及一种桥梁减震装置，包括桥墩以及通过桥梁连接在桥墩顶部的桥面，桥梁设置呈Y型混凝土结构，且桥梁顶部左右对称设置有第一减震机构，第一减震机构包括固定连接在桥梁顶部的顶架以及位于顶架顶部外侧的凹架，顶架中部设置有支撑台，支撑台上侧与凹架底侧内壁之间固定连接有第一弹簧，凹架顶部内侧壁开设有缓冲槽，顶架顶端插入缓冲槽内；本发明通过第一弹簧，有效对桥面进行纵向减震，同时通过橡胶支座连接桥面可与支撑凹座，以及通过第一钢板与四氟板的相对滑动，从而不仅有效对桥面进行水平方向减震，而且便于桥面快速复位，也可缓冲桥面受到纵向压力；继而实现纵向与水平方向的减震。
