A bridge guardrail that decomposes the impact force of vehicles

Abstract

The invention relates to a bridge guardrail for decomposing the impact force of a vehicle, comprising a base body, a crossbeam placed above the base body and a plurality of ribs for supporting the crossbeam, the plurality of ribs are evenly distributed along the length direction of the crossbeam, and the base body It is connected with the beam through a plurality of steering arms, and the steering arm includes two arms placed symmetrically up and down between the base and the beam and a vertical bar placed between the two arms, and the lower arm One end is rotatably connected to the base body via the vertical axis, one end of the upper pivoting arm is rotatably connected to the beam via the vertical axis, the other end of the pivoting arm faces the direction of incoming traffic on the bridge, and the two ends of the vertical bar are respectively connected to the The other ends of the two pivoting arms are rotationally connected; the steering curved arm is connected to the base through a torsion device; the invention can buffer the impact of the vehicle, and intervene in the movement of the vehicle to change the direction of movement, preventing the vehicle from rushing out of the bridge deck , and at the same time reduce the risk of secondary injury to the occupants of the vehicle.

Description

technical field [0001] The invention relates to a bridge safety protection device, in particular to a bridge guardrail for decomposing the impact force of a vehicle. Background technique [0002] Bridges are essentially suspended roads used to connect different regions. Therefore, driving safety on bridges is particularly important. Once a vehicle rushes out of the bridge deck, it will cause unforeseen catastrophic consequences. Existing bridges mainly rely on guardrails for vehicle protection, but due to the When a collision occurs, the impact inertia is large. After hitting the guardrail, it will often roll along the impact direction and fall under the bridge, or break the guardrail and rush out of the bridge deck, or bend the guardrail and fly out of the bridge along the curved guardrail. In any case, the vehicle must fall under the bridge after leaving the bridge deck, causing more serious safety accidents. [0003] At the same time, due to the rigid connection between ...

Problems solved by technology

[0005] In view of the above situation, in order to make up for the technical deficiencies in the existing technology, the present invention provides a bridge guardrail that decomposes the impact force of vehicles to solve the problem that the existing bridge guardrail cannot buffer the impact of vehicles, and cannot actively intervene and impact vehicle movement. In an instant, the people on the vehicle are likely to cause secondary injuries, and avoid vehicles rushing out of the bridge deck and causing greater safety accidents
