Buffering and energy-absorbing highway anti-collision guardrail

Abstract

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.

Description

technical field [0001] The invention belongs to the field of road guardrails, in particular to an energy-absorbing buffer and energy-absorbing road crash guardrail. Background technique [0002] At present, crash barriers are installed on both sides of the expressway to withstand the impact of the vehicle when the vehicle is out of control, and buffer the impact of the vehicle to reduce the damage to the vehicle. The current anti-collision barriers are generally provided with wavy guardrails. When the guardrails are hit by vehicles, they absorb the collision energy through the elastic deformation of the guardrails to achieve a buffering effect on the vehicle. However, due to the deformation of the guardrails only To buffer the vehicle, the buffering effect is limited. When the vehicle hits the guardrail at a high speed, the guardrail still cannot effectively buffer the vehicle, which is easy to cause serious damage to the vehicle, and when the guardrail is hit by the vehicle...

The current anti-collision barriers are generally provided with wavy guardrails. When the guardrails are hit by vehicles, they absorb the collision energy through the elastic deformation of the guardrails to achieve a buffering effect on the vehicle. However, due to the deformation of the guardrails only To buffer the vehicle, the buffering effect is limited. When the vehicle hits the guardrail at a high speed, the guardrail still cannot effectively buffer the vehicle, which is easy to cause serious damage to the vehicle, and when the guardrail is hit by the vehicle, Guardrails are easily damaged
