Description

Urban road traffic guardrail safety device

Technical Field

The utility model relates to the technical field of traffic guardrails, in particular to a safety protection device for an urban road traffic guardrail.

Background

Traffic barriers are installed on roads for separating motor vehicles, non-motor vehicles and pedestrian traffic to improve the safety of road traffic, improve traffic order, also to block bad traffic behavior, block pedestrians or bicycles or motor vehicles attempting to cross the road, such barriers generally have certain height, density and strength requirements for the barriers, which are mostly supported by a plurality of vertical barriers to form a barrier frame, and two sides are connected to mounting posts to be fixed on the road by the mounting posts.

In the prior art, some protection structures are usually additionally arranged on the traffic guardrail to reduce the impact of vibration generated by collision of the non-motor vehicle on a driver, thereby playing a role in protection. However, some guardrails with protective structures have a number of disadvantages in practical use. For example, some bumper guardrails absorb energy through structures such as elastic materials or springs, but energy absorption and dissipation are one process, and energy which is not completely absorbed in the process can cause rebound or sway of a collided vehicle, thereby causing secondary injury to personnel in the vehicle. For example, after the electric vehicle collides with the guardrail, due to the rebound effect of force, the vehicle may move a certain distance to the opposite direction again, so that personnel on the vehicle collide with the vehicle body under the inertia effect, and secondary injury is caused to the driver. In addition, the integration degree of part of the guardrail is higher, and only part of the structure is possibly damaged when collision occurs, but the place which is usually required to be replaced is far larger than the place which is actually damaged due to the higher integration degree, and the maintenance and replacement costs are certainly increased. Therefore, how to design a secondary injury to a driver caused by resilience of force after collision between a vehicle and a guardrail, and save maintenance and replacement cost becomes a key problem in the urban road traffic guardrail technology.
