Anti-collision protective fence for highway bridge
The invention discloses an anti-collision protective fence for a highway bridge, and relates to the technical field of protective fences. Comprising a stand column, a mounting seat is fixedly mounted on the stand column, an extrusion block penetrates through the interior of the mounting seat, a protective fence is fixedly mounted on the outer wall of the extrusion block, an energy absorption mechanism is arranged on the inner wall of the mounting seat, a transverse plate is slidably connected to the inner wall of the stand column, and a limiting mechanism is arranged in the stand column. A mounting rod is fixedly mounted on the inner wall of the stand column, and a transmission mechanism is arranged in the stand column. According to the anti-collision protective fence for the highway bridge, impact force can be buffered through the arrangement of the energy absorption mechanism, when an automobile collides with the protective fence, a hinge block moves leftwards to extrude the end of a supporting rod so that a reset spring can be compressed, and finally part of the impact force is absorbed through the reset spring in the compression process; and therefore, the protective fence is prevented from being damaged due to overlarge impact force.
本发明公开了一种抗撞击的公路桥梁用防护栏，涉及防护栏技术领域。包括立柱，所述立柱上固定安装有安装座，所述安装座的内部贯穿有挤压块，所述挤压块的外壁上固定安装有防护栏，所述安装座的内壁上设置有吸能机构，所述立柱的内壁上滑动连接有横板，所述立柱的内部设置有限位机构，所述立柱的内壁上固定安装有安装杆，所述立柱的内部设置有传动机构。该抗撞击的公路桥梁用防护栏通过吸能机构的设置能够对冲击力进行缓冲，汽车撞击防护栏时通过铰接块向左运动对支杆的端部进行挤压使复位弹簧被压缩，最后通过复位弹簧在压缩的过程使冲击力一部分被吸收，进而防止了冲击力度过大导致防护栏被损坏。
