Deceleration anti-collision guardrail equipment for highway traffic safety facilities

Abstract

The highway traffic safety facility deceleration anti-collision guardrail equipment comprises a plurality of bases, and sliding grooves are formed in the tops of the bases in the length direction of the bases; the bottom of the first handrail is slidably arranged in the sliding groove, the first transmission structure is arranged in the sliding groove, a movable piece is connected with the first handrail, and a fixed piece is connected with the inner wall of the sliding groove. The supporting plates are arranged between every two adjacent bases, the lower ends of the second railings are rotationally arranged in mounting holes of the supporting plates, and the upper ends of the second railings are connected through connecting structures. By arranging the first transmission structure, when a vehicle collides with the guardrails, the first handrail can rotate in the normal running direction of the vehicle, the second handrail is driven by the second transmission structure to rotate, and therefore the vehicle is straightened; and meanwhile, the first elastic piece and the buffer ring can buffer the impact force of the vehicle, so that the vehicle is prevented from rushing out of the guardrail or impacting a reverse road.

Description

technical field [0001] The invention relates to the technical field of traffic safety facilities, in particular to a deceleration and anti-collision guardrail device for highway traffic safety facilities. Background technique [0002] A traffic guardrail is a traffic safety facility that is set on the outside of the road shoulder, traffic divider, and sidewalk teeth. The collision energy is absorbed by self-deformation or the vehicle climbs up, thereby changing the driving direction of the vehicle, preventing the vehicle from going out of the road or entering the opposite lane, and preventing the vehicle from rushing out of the road and causing a rollover accident, especially if it is set at the bends and dangerous roads in the mountains The traffic guardrail, for motor vehicle drivers, can attract sufficient attention in the distance, so that they can increase their vigilance, and can also guide the driver's sight when passing through, helping them to operate correctly. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the vehicle deviates from the driving lane and hits the railing, the vehicle and the railing will have a rigid collision, which will cause a large impact force on the vehicle and passengers, and the vehicle can only be buffered by the deformation of the vehicle. Reversely, for the problem of collision with the oncoming vehicle, provide a deceleration and anti-collision guardrail equipment for road traffic safety facilities
