Buffering and energy-absorbing highway anti-collision guardrail
The invention relates to a buffering and energy-absorbing highway anti-collision guardrail. The guardrail comprises a pre-buried supporting plate and a plurality of inclined supporting rods connected to one side wall of the pre-buried supporting plate, a plurality of main anti-collision mechanisms are connected to the other side wall of the pre-buried supporting plate, auxiliary buffering mechanisms are arranged in gaps among the main anti-collision mechanisms, and the two ends of each auxiliary buffering mechanism are connected with the main anti-collision mechanism and the embedded supporting plate correspondingly. According to the buffering and energy-absorbing highway anti-collision guardrail, progressive buffering is conducted on out-of-control vehicles through the main anti-collision mechanism and the auxiliary buffering mechanisms, and the buffering process can be more stable and the buffering effect is better through buffering of multiple sets of buffering components. When an anti-collision plate is impacted, the anti-collision plate moves towards a middle limiting column, in the moving process, the auxiliary buffering mechanisms play a role in auxiliary buffering, meanwhile, the anti-collision plate can be prevented from being broken or deformed due to collision, the situation that the fixing column or the hollow sleeve is broken due to uneven stress of the anti-collision plate is effectively avoided, and safety is higher.
本发明涉及一种缓冲吸能的公路防撞护栏，包括预埋支撑板以及连接在预埋支撑板一侧壁上的若干个斜向支撑杆，所述预埋支撑板的另一侧壁上连接有若干个主防撞机构，若干个主防撞机构之间的间隙处设有辅助缓冲机构，所述辅助缓冲机构的两端分别与主防撞机构和预埋支撑板连接。该缓冲吸能的公路防撞护栏，通过主防撞机构以及辅助缓冲机构对失控车辆进行递进式缓冲，多组缓冲部件的缓冲可以使得缓冲过程更加的稳定且缓冲效果更好，当防撞板受到冲击时，向中部限位柱处移动，在移动过程中，辅助缓冲机构起到辅助缓冲的作用，同时可以防止防撞板因撞击而断裂或者是形变，有效的避免防撞板受力不均匀而导致固定柱或中空套管断裂的情况出现，安全性更高。
