Abstract

The invention belongs to the technical field of highway anti-collision guardrail, in particular to an anti-collision guardrail for an expressway, comprising a vertical plate, a bottom plate, a blocking plate, a shock absorbing bar, a movable pin and a stop arc plate. The upper end of the stop arc plate is hinged on the bottom surface of the vertical plate, and a torsion spring is arranged at the hinge of the stop arc plate. The left side of the vertical plate is provided with a blocking plate; A low end of that blocking plate is fixedly connected with the left end of the bottom plate, and a shock absorbing bar is arranged between the blocking plate and the vertical plate; As that upright plate is arranged as an L-shaped plate andarticulated the corner of the upright plate to the left end of the bottom plate, a stop arc plate is arranged under the vertical plate, At the same time, a group of V-shaped grooves are arranged on the upper surface of the bottom plate to realize that the rightend of the vertical plate lifts the front end of the car after the vertical plate is hit by the car, so that the front wheels of the car cannot land on the ground, the front wheels of the car are prevented from continuing to transmit kinetic energy to the car, further more serious collision is avoided, and the safety of the vehicle is further protected.

Description

technical field

[0001] The invention belongs to the technical field of highway anti-collision guardrails, in particular to an expressway anti-collision guardrail. Background technique

[0002] The highway guardrail, as the isolation boundary between the highway and the external environment and the last barrier to protect vehicles, plays a vital role in ensuring the safety of vehicles. Especially in special areas such as cliffs, viaducts, winding mountain roads, emergency turns, and steep downhill turns, cars lost control and crashed into guardrails, resulting in car crashes and fatal accidents. The speed of the vehicle on the expressway is relatively fast. Once an accident occurs, the impact force will be very large. If the guardrail cannot have a good buffering effect, the driver and the vehicle will suffer more damage. Therefore, a guardrail with a good buffering effect is needed.

[0003] At present, the protective devices on both sides of the expressway are composed of ...
