Problems solved by technology

[0004] The connection method of the highway safety guardrail adopts rigid connection. When the vehicle collides with the safety guardrail, the rebound degree of the vehicle is relatively large, and it is easy for the vehicle to rebound to the side of the normal driving vehicle and cause secondary accidents.

Embodiment Construction

[0019] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0020] Such as Figure 1 to Figure 3 A forced movable energy-absorbing safety guardrail is shown, which includes several uprights 1 and guardrail boards 2 between adjacent uprights 1, and is characterized in that it includes a connector 3, a limiter 4 and a connection Article 5.

[0021] The connector 3 is located between the column 1 and the guardrail 2. The connector 3 includes a rigid layer 31 and a flexible layer 32. The rigid layer 31 is placed on the outside of the flexible layer 32 to wrap the flexible layer 32 inside; the rigid layer 31 includes a connecting back cover 1. Connect the front cover and connect the side cover; connect the rear cover and the upright column 1 through bolts, which are narrow at the top and bottom, and wide in the middle; shape, the conne...

Abstract

The invention relates to a forced movable energy-absorbing safety guardrail. The safety guardrail comprises a plurality of vertical posts and guardrails located between adjacent vertical posts. The safety guardrail is innovatively characterized by comprising connectors, limiters and connection bars. The forced movable energy-absorbing safety guardrail adopts flexible connectors; the collision energy can be absorbed to a maximum extent under the precondition that the barrier effect of the safety guardrail is ensured, the rebound degree of vehicles colliding against the safety guardrail is greatly reduced, and the secondary accident rate caused by the rebound degree is reduced.

Description

technical field [0001] The invention relates to the traffic field, in particular to a forced movable energy-absorbing safety guardrail. Background technique [0002] Safety guardrails (including anti-collision buffer facilities) mainly refer to municipal guardrails, traffic isolation guardrails, expressway W-shaped guardrails (wave guardrails), and the main functions of road guardrails: First, they can prevent vehicles from driving out of the road, or prevent out-of-control vehicles from crossing the central separation The second is that the trajectory of the vehicle collision barrier should be able to transition smoothly, so that the vehicle can return to the normal driving direction and reduce the possibility of secondary accidents. The third is that once the out-of-control vehicle collides with the guardrail, it can Reduce the damage to the driver and passengers. Fourth, it can induce the driver's sight, and can clearly see the direction of the road and the outline of the...
