Description

Highway guardrail buffer structure

Technical Field

The utility model relates to a traffic protection facility technical field, very much relate to a highway guardrail buffer structure.

Background

Along with the development of social economy, vehicles are more and more popular, and in order to guarantee driving safety, a protection device needs to be arranged on a road to prevent the vehicles from rushing out of a road edge due to out-of-control. At present, most of guardrails are composed of upright posts and guard plates fixed on the upright posts, and the upright posts and the guard plates are made of rigid materials and are rigidly connected together; however, the structure has no buffer action or has little buffer action on the vehicle running at high speed, the vehicle running at high speed collides against the guardrail, the vehicle and the guardrail are in rigid contact, the vehicle is easily damaged, a driver is injured, and the accident of vehicle damage and human death can be caused in more serious cases.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a structural design is reasonable, and buffering effect is good, is favorable to improving the safeguard effect, improves the highway guardrail buffer structure of security.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a highway guardrail buffering structure is characterized by comprising upright columns, a first protection plate and a second protection plate, wherein the first protection plate and the second protection plate are transversely connected to the upright columns and are respectively arranged at the upper ends and the lower ends of the upright columns; a plurality of vertically arranged buffer cylinders are uniformly distributed between every two adjacent upright columns, and the upper end and the lower end of each buffer cylinder are rotatably arranged on the first protection plate and the second protection plate; the first protection plate is fixedly installed on the stand column through bolts, and the second protection plate is installed on the stand column through an elastic part, so that the distance between the second protection plate and the stand column can be changed under the action of external force.

By adopting the structure, the second protective plate is arranged on the upright post through the elastic part, so that when a vehicle is out of control and collides with the guardrail, the elastic part deforms under the action of vehicle impact to absorb impact energy. In addition, when the vehicle is out of control, the slant of front side usually strikes the guardrail, and vertical being provided with rotatable buffer cylinder between first guard plate and the second guard plate for the vehicle contacts the buffer cylinder earlier, and the buffer cylinder receives the slant and collides the back, converts the kinetic energy of vehicle into the rotation of self, and the rotation of buffer cylinder also can guide the locomotive to deflect towards the guardrail direction simultaneously, thereby can minimize the impact force of vertical action on the guardrail, thereby further improve the security of vehicle. After the elastic part and the buffer cylinder are used for dual energy absorption, the first guard rail is fixedly arranged on the upright post, so that the first guard rail can be effectively prevented from being damaged by vehicle collision to buffer out of the guard rail, and the safety is further improved.

Further, first guard plate and second guard plate are located respectively the inboard and the outside of stand, install the upper end of buffer cylinder the outside of first guard plate, the lower extreme is installed the inboard of second guard plate.

Because the second guard plate is located the outside of stand for the second guard plate can move towards the direction that deviates from the stand under the striking of vehicle, and it is bigger to move the space, increases the energy-absorbing effect. In addition, the relative one side of first guard plate of buffer cylinder installation and second guard plate can enough guarantee the vertical setting of barrel, can also make full use of the width of stand, avoids the buffer cylinder to occupy too much road space.

Furthermore, elastomeric element is including passing the second guard plate is installed screw rod on the stand with wear to establish backing plate on the screw rod, the backing plate is located the outside of second guard plate, the butt joint cover is established between backing plate and the second guard plate coil spring on the screw rod.

Therefore, the second protection plate can compress the spiral spring along the screw rod under the collision action of the vehicle, and the spiral spring absorbs impact energy, so that the guardrail has a buffering effect.

Further, the buffer cylinder includes barrel and pivot, pivot both ends fixed mounting be in on first guard plate and the second guard plate, have the coaxial through-hole that link up the setting on the barrel, the internal diameter of through-hole with the diameter phase-match of pivot, the barrel rotationally wears the dress in the pivot.

Like this, with pivot fixed mounting on first guard plate and second guard plate, and set up the through-hole on the barrel, make the relative pivot of barrel rotate, can make the structure of guardrail simpler, reduce manufacturing cost and maintenance cost.

Furthermore, the barrel is formed by plastic injection molding, and the interior of the barrel is filled with foam.

Furthermore, have on the excircle face of buffer cylinder along the reflection of light indication subsides of circumference equipartition setting, the middle part of reflection of light indication subsides extends along circumference and forms "a Chinese character" shape relative its both ends.

During the installation, can follow the direction of travel setting on this side road with the "shape" of sticking is instructed in the reflection of light of buffer cylinder inboard department for the in-process of driving a vehicle at night, under the vehicle light effect, the border of instruction road, the guide vehicle is gone along the right direction, improves the driving safety at night. Because the reflection of light indicates to paste along the circumference equipartition of buffer cylinder a plurality ofly for the buffer cylinder is in any position, can both have the reflection of light that supplies to illuminate and indicate to paste in the inboard.

Further, the height of the first protection plate is 0.5-1 m.

In this way, it is ensured that the vehicle does not rush out of the first fender.

Furthermore, the first protection plate and the second protection plate are both double-wave-shaped guardrail plates.

To sum up, the utility model has the advantages of structural design is reasonable, and buffering effect is good, is favorable to improving protective effect, improves the security.
