Assembly type buffering beam falling prevention device
The invention relates to the field of bridge construction, and particularly discloses an assembly type buffering beam falling prevention device which comprises a pier. A vertically-arranged anti-collision plate is fixed to the top of the pier, the anti-collision plate coincides with the center line of the pier, fixing frames are symmetrically arranged on the two sides of the anti-collision plate,and connecting plates are hinged to the movable ends of the fixing frames. Two sections of beam bodies are symmetrically arranged on the pier, cavities for containing the connecting plates are formedin the end faces of the beam bodies, entrances and exits are formed in the bottom walls in the cavities, the widths of the entrances and exits are larger than those of the connecting plates and the fixing frames, connecting rods are hinged to the connecting plates and are spring telescopic rods, and the movable ends of the connecting rods extend out of the entrances and exits to be detachably connected to the pier. A plurality of hydraulic dampers are horizontally hinged to the inner walls of the two sides of the cavities, and the other ends of hydraulic dampers are detachably hinged to the connecting plates. Limiting blocks are connected to the two side walls of the connecting plates through bolts, and gaps are reserved between the limiting blocks and the inner side walls of the cavities.The problems that an existing beam falling prevention facility is prone to damage and is not easy to replace after being damaged are solved.
本发明涉及桥梁建筑领域，具体公开了一种装配式缓冲防落梁装置，包括桥墩，桥墩顶部固定有竖直设置的防撞板，防撞板与桥墩中线重合，防撞板的两侧对称设置有固定架，固定架的活动端铰接有连接板；桥墩上对称设置有两段梁体，梁体的端面均开设有容纳连接板的腔室，腔室内的底壁开设有出入口，出入口的宽度大于连接板、固定架的宽度，连接板上铰接有连接杆，连接杆为弹簧伸缩杆，连接杆的活动端伸出出入口可拆卸连接在桥墩上；腔室两侧内壁上水平铰接有若干液压阻尼器，液压阻尼器另一端可拆卸铰接在连接板上；连接板的两侧壁螺栓连接有限位块，限位块与腔室内侧壁之间预留有间隙；本发明意在解决现有防落梁设施易受损，且受损后不易更换的问题。
