Anti-collision protection height limiting device for highway bridge
The invention relates to an anti-collision protection height limiting device for a highway bridge. The device comprises two groups of buried energy reduction devices, two groups of anti-collision column devices and two groups of anti-collision height rod devices, wherein the two groups of buried energy reduction devices are respectively connected with bottom ends of the anti-collision column devices, and the anti-collision height rod devices are connected with inner sides of top ends of the two groups of anti-collision column devices. The device is advantaged in that the arrangement of the road height limiting frame is optimized, a fixing mode adopted by a traditional fixed road height limiting frame is changed, the structure is improved to be a device capable of flexibly changing the selfstructure, the device has the characteristic of avoiding secondary damage, when an automobile collides with the height limiting rod, the device can prevent hard collision with an automobile and reduce damage to the automobile after collision, the slidable buried energy reduction device is arranged on the bottom side, impact energy borne by the automobile colliding with the anti-collision column device is reduced, and the device adopts an upper-lower three-section buffer structure, has different collision effects and traction effects and is suitable for popularization and application.
本发明涉及一种公路桥梁用防撞击保护限高装置，包括地埋减能装置、防撞柱装置、防撞高度杆装置，所述地埋减能装置、防撞柱装置均设有两组，所述两组地埋减能装置分别连接在防撞柱装置的底端，所述防撞高度杆装置连接在两组防撞柱装置的顶端内侧。本发明优化了道路限高架的设置，改变传统固定式道路限高架采用的固定方式，改进为一种能够灵活改变自身结构的设置，而且设备具有避免二次伤害的特点，当汽车碰撞到限高杆的时候，设备可以实现防止硬性碰撞汽车，减少汽车碰撞后所受到的伤害，而且底侧设置了可以滑动的地埋减能装置，减轻汽车碰撞到防撞柱装置所受到的冲能，设备采用上下三段的缓冲结构，分别具有不同的碰撞效果和牵拉效果，宜推广使用。
