Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a highway emergency escape lane guardrail. Background Art

[0002] The primary task of highway emergency lane guardrails is to ensure that vehicles can safely slow down and stop in an out-of-control state, or to absorb the impact force when colliding with the guardrail to prevent the vehicle from causing greater harm.

[0003] When designing highway emergency lane guardrails, measures should be taken to reduce the damage caused by accidents. Currently, guardrails mostly absorb impact forces by using elastic buffer mechanisms. However, since the setting direction of the elastic buffer mechanism is fixed, it is difficult to keep the impact force and the rebound direction of the elastic buffer mechanism consistent, so that the elastic buffer mechanism is often subjected to a large shear force, affecting the service life of the elastic buffer mechanism. Therefore, this solution provides a highway emergency lane guardrail, in which the force direction of the elastic buffer mechanism is kept consistent with the deformation direction as much as possible. Utility Model Content

[0004] The utility model aims at least to solve the problem in the prior art that the deformation direction of a buffer structure arranged in a fixed direction is difficult to coincide with the direction of the impact force.

[0005] The present invention provides a highway emergency escape lane guardrail, which is achieved by the following specific technical means: comprising a cross bar, on which a vertical tube is fixed, on which an annular seat 1 and an annular seat 2 are symmetrically slidably provided, an elastic member is connected between the annular seat 1 and the annular seat 2, and at the same time, the annular seat 1 and the annular seat 2 are hingedly connected to the circumference of each of the annular seat 1 and the annular seat 2, a vertical plate is hingedly connected between a group of connecting arms on the annular seat 1 and a corresponding group of connecting arms on the annular seat 2, and a plurality of groups of vertical plates are rotatably sleeved with rotating drums on the outer sides thereof, and when a vehicle collides with the rotating drum from different angles, the force deviating from the radial direction of the vertical tube is absorbed by the rotating drum as the force driving the rotating drum to rotate, and the force in the radial direction of the vertical tube is transmitted to the vertical plate located at the corresponding position outside the vertical tube, so that the elastic member undergoes elastic deformation to absorb the impact force from the radial direction.

[0006] Preferred technical solution 1: a ball is rotatably embedded in the vertical plate, and the vertical plate contacts the inner wall of the drum through the ball.

[0007] Preferred technical solution 2: A protective barrel is provided on the outer fixed sleeve of the rotating drum to protect the rotating drum.

[0008] Preferred technical solution three: an annular hollow chamber is formed between the protective barrel and the rotating drum, and the annular hollow chamber is used to absorb the first wave of impact force.

[0009] Preferred technical solution four: the annular hollow chamber is filled with gas, and thin plates are provided on the upper and lower end surfaces of the protective barrel. The strength of the thin plates is lower than that of the protective barrel. After the protective barrel is deformed to a certain extent, the squeezed gas breaks through the thin plates and is discharged.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. Multiple groups of vertical plates arranged around the vertical pipe can directly receive the impact force from the radial direction, and at the same time, the rotation of the drum can absorb the impact force in the tangential direction, so as to avoid the shear damage of the buffer structure caused by a large amount of impact force and improve the overall service life;

[0012] 2. When the first wave of impact force is received, the setting of the protective barrel and gas disintegrates and dissipates energy through the dispersion of gas, thereby reducing the amount of energy transferred. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the plurality of vertical plates 7 are in contact with the inner wall of the rotating drum 8 to support the rotating drum 8. When the vehicle hits the rotating drum 8 from different angles, the force deviating from the radial direction of the vertical tube 2 is absorbed by the rotating drum 8 as the force driving the rotating drum 8 to rotate, and the force in the radial direction of the vertical tube 2 is transmitted to the vertical plates 7 located at the corresponding position outside the vertical tube 2. The radial movement of the vertical plates 7 changes the distance between the annular seat 1 3 and the annular seat 2 4, thereby starting the elastic member 5 to undergo elastic deformation to absorb the impact force from the radial direction.

The elastic member 5 is connected to the slide plate 11 and the slide plate 2 12. A protrusion 13 is fixed in the middle part of the vertical tube 2. The elastic member 5 is provided with two groups, namely, a spring 1 51 and a spring 2 52. The spring 1 51 is connected between the slide plate 1 11 and the top wall of the vertical tube 2, and the spring 2 52 is connected between the vertical plate 7 2 and the bottom wall of the vertical tube 2.

When the protective barrel 10 is subjected to a large impact, it will be concave and deformed;

[0025] The annular hollow chamber is filled with gas, and thin plates 101 are provided on the upper and lower end surfaces of the protective barrel 10. The strength of the thin plate 101 is lower than that of the protective barrel 10. After the protective barrel 10 is deformed to a certain extent, the squeezed gas breaks through the thin plate 101 and is discharged, releasing the pressure and dissipating part of the impact force to prevent it from continuing to be transmitted inward.
