Embedded buffer energy dissipation type bridge anti-beam-falling device
The invention relates to the field of bridge construction, and particularly discloses an embedded buffer energy dissipation type bridge anti-beam-falling device which comprises a pier, a support is fixed to the top of the pier, a bridge is arranged at the top of the support, inclined connecting grooves are formed in the bridge, the connecting grooves penetrate through the bridge and extend into the support, and limiting columns are arranged in the connecting grooves. Through grooves are formed in the side walls of the two sides of the support, fixing rods are arranged in the through grooves, annular grooves are formed in the fixing rods, damping rods are distributed in the circumferential direction of the annular grooves, the tops of the damping rods are sleeved with sleeves, the sleeves are abutted against the limiting columns, first damping springs are fixed between the annular grooves and the sleeves, and the damping rods are sleeved with the first damping springs; a plurality of transverse grooves are distributed in the bottoms of the annular grooves in the circumferential direction, sliding blocks are slidably connected into the transverse grooves and connected to the sleevesthrough inclined rods, and second damping springs are fixed between the sliding blocks and the transverse grooves. Therefore, problems that an existing bridge anti-falling beam device is complex in structure, high in manufacturing cost, inconvenient to construct and the like are solved.
本发明涉及桥梁建筑领域，具体公开了一种内嵌缓冲耗能型桥梁防梁落装置，包括桥墩，桥墩顶部固定有支座，支座顶部放置有桥梁，桥梁上开有倾斜的连接槽，连接槽贯穿桥梁并延伸至支座内，连接槽内均设置有限位柱；支座两侧侧壁上均开设有通槽，通槽内设置有固定杆，固定杆上开设有环形槽，环形槽周向分布有减震杆，减震杆顶部套设有套筒，套筒与限位柱相抵，环形槽与套筒之间固定有第一减震弹簧，且第一减震弹簧套设在减震杆上；环形槽底部周向分布有若干横槽，横槽内均滑动连接有滑块，滑块通过斜杆连接在套筒上，滑块与横槽之间固定有第二减震弹簧；本发明意在解决现有桥梁防落梁装置存在的结构复杂、造价较高、施工不便等问题。
