A flexible beam falling prevention device relates to an anti-seismic device for a bridge and comprises a connecting cable and an anchoring part. The anchoring parts are connected to the two ends of the connecting cable in an anchoring mode respectively and connected with the side face of the pier and the bottom of the box girder respectively, and the connecting cable is a high-strength steel strand inhaul cable or a high-strength steel wire rope. The anchoring part comprises an anchoring cylinder, a fork lug and a universal hinge bracket; the anchoring cylinders are respectively anchored and connected to two ends of the connecting cable; one end of the fork lug is fixedly connected with the anchoring cylinder, and the other end is rotationally connected with the universal hinge bracket; the universal hinge brackets are installed on the side faces of the bridge piers and the bottoms of the box girders respectively. A buffer is further installed between the fork lug at any end of the bridge pier or the box girder and the anchoring cylinder. Multi-directional anti-beam-falling limiting can be achieved at the same time, the instant impact test requirement can be met, and the energy dissipation structure is simple in overall structure, clear in stress, easy to achieve, convenient and efficient to construct and install and particularly suitable for anti-seismic measures of simply-supported system beam bridges.
一种柔性防止落梁装置，涉及一种桥梁用抗震装置，包括连接索、锚固件；锚固件分别锚固连接在连接索的两端，且分别与桥墩侧面、箱梁底部相连接所述的连接索采用高强钢绞线拉索或高强钢丝绳索；所述的锚固件包括锚固筒、叉耳、万向铰托座；锚固筒分别锚固连接在连接索的两端；叉耳的一端与锚固筒固定连接，另一端与万向铰托座转动连接；万向铰托座分别安装在桥墩的侧面和箱梁的底部；在桥墩或箱梁任意一端的叉耳和锚固筒之间还安装有缓冲器。本发明能同时实现多方向的防落梁限位，能满足瞬间冲击试验要求，其耗能结构整体结构简洁，受力明确，易于实现，且施工安装方便高效，特别适用于简支体系梁桥的抗震措施。
