Anti-seismic and anti-falling beam structure
The invention belongs to the field of anti-falling beams, and particularly relates to an anti-seismic and anti-falling beam structure. An anti-seismic seat is movably clamped at the top of a bridge abutment, a fixed column is fixedly connected to the bottom of an anti-falling beam body, a movable plate is slidably connected into a mounting cavity in the anti-seismic seat, and the bottom end of thefixed column extends into the mounting cavity and is fixedly connected with the bottom of the movable plate; two telescopic rods are symmetrically and fixedly connected to the inner wall of the top of the mounting cavity, the bottom ends of the two telescopic rods are fixedly connected with the top of the moving plate, two ball screws are symmetrically and rotationally connected to the inner wallof the bottom of the mounting cavity, and screw nuts are in threaded connection with the two ball screws; two fixing rods are symmetrically and fixedly connected to the tops of the two lead screw nuts, the top ends of the four fixed rods are fixedly connected with the bottom of the moving plate, the two ball screws are fixedly sleeved with gears, and damping grooves are formed in the inner wallsof the two sides of the mounting cavity, so the problems that an existing anti-falling beam is single in anti-seismic structure and poor in anti-seismic effect are solved.
本发明属于防落梁领域，尤其涉及一种抗震防落梁结构，桥梁墩台的顶部活动卡装有抗震座，防落梁主体的底部固定连接有固定柱，抗震座上安装腔室内滑动连接有移动板，固定柱的底端延伸至安装腔室内并与移动板的底部固定连接，安装腔室的顶部内壁上对称固定连接有两个伸缩杆，两个伸缩杆的底端均与移动板的顶部固定连接，安装腔室的底部内壁上对称转动连接有两个滚珠丝杠，两个滚珠丝杠上均螺纹连接有丝杠螺母，两个丝杠螺母的顶部均对称固定连接有两个固定杆，四个固定杆的顶端均与移动板的底部固定连接，两个滚珠丝杠上均固定套设有齿轮，安装腔室的两侧内壁上均开设有减震槽，解决现有的防落梁抗震结构单一，抗震效果不佳的问题。
