A bridge guardrail that changes the direction of vehicle impact

Abstract

The invention relates to a bridge guardrail that changes the impact direction of vehicles, so as to solve the problems that the existing guardrails cannot buffer, cannot intervene with vehicles and easily cause secondary injuries to personnel, and avoid greater safety accidents caused by vehicles rushing out of the bridge deck , including a substrate, a beam placed above the substrate, and a plurality of vertical rods for supporting the beam. There is an arc-shaped chute facing the inner side of the bridge on the substrate. There is a slider in the arc-shaped chute, and there is a sliding block on the slider. The anti-collision bar vertically arranged above the block has an arc-shaped guide groove on the beam, and the arc-shaped chute corresponds to the arc-shaped guide groove up and down and has the same arc. The upper end of the anti-collision bar slides in the arc-shaped guide groove; There is a push slider that slides vertically. The push slider and the slider are universally hinged through a connecting rod, and the connecting rod is inclined to the outside of the beam; it also includes a gravity beam placed above the beam. There are a plurality of vertical ejector rods below the gravity beam, and the lower ends of the vertical ejector rods slide downwards through the crossbeam and contact with the push slider.

Description

technical field [0001] The invention relates to a bridge safety protection device, in particular to a bridge guardrail which changes the collision direction of vehicles. Background technique [0002] Since the two sides of the bridge are usually water or mountains, driving safety on the bridge is particularly important. Once the vehicle rushes out of the guardrail, it will cause unpredictable and catastrophic consequences. The impact inertia is large, and after hitting the guardrail, it will often roll over and fall under the bridge, or crash the guardrail and rush out of the bridge deck, or bend the guardrail and fly out of the bridge deck along the curved guardrail. In any case, the vehicle After leaving the bridge deck, it will inevitably fall under the bridge, which will cause serious follow-up injuries to the people on board. [0003] At the same time, due to the rigid connection between the existing guardrail and the bridge, when the vehicle hits, the guardrail will c...
