Embodiment approach

[0037] An elastic buffer device for a bridge anti-collision guardrail and an implementation method thereof, comprising the following implementation steps:

[0038] (1) Pass the slide bar 1 through the prefabricated column 13, and fix it with a block 4 at one end;

[0039] (2) Put spring 6 on the other end of slide bar 1;

[0040] (3) Prefabricate the “[”-shaped cover plate 3 with T-shaped chute 10 on the inside, and the T-shaped slider 11 is embedded in the T-shaped chute 10;

[0041] (4) Connect and fix the “[” type cover plate 3 with the slide bar 1;

[0042] (5) Fix the first hinge block 5 and the column 13, and connect the connecting rod 6 to the first hinge block (5) through the hinge rod 1A;

[0043] (6) Use the hinge rod 2A to connect the second hinge block 7 with the connecting rod 6, and fix the second hinge block 7 with the T-shaped slider 11;

[0044] (7) Put the vertical spring 8 on the cylinder head 15 of the second hinged block 7 and the fixed block 9, connect...

Abstract

The invention discloses an elastic buffering device of an anti-collision guardrail for a bridge and an implementation method of the elastic buffering device. The elastic buffering device comprises a stand column [-shaped cover plate, a sliding rod, a check block and a buffering device body. The two sliding rods penetrate through the stand column in the height direction, one ends of the sliding rods are fixedly connected with the [-shaped cover plate, the other ends of the sliding rods are fixedly connected with the check blocks, and the buffering device is arranged between the stand column andthe [-shaped cover plate. The vertical buffer device comprises a first hinge block, a connecting rod, a second hinge block, a vertical spring, a fixing block, a T-shaped sliding groove and a T-shapedsliding block. The horizontal springs and the vertical buffer devices are good in buffer effect and high in energy consumption, all the components can be conveniently connected together through the hinge rods, and construction is convenient, rapid and efficient.

Description

technical field [0001] The invention relates to the technical field of roads and bridges, in particular to an elastic buffer device for a bridge anti-collision guardrail and an implementation method thereof. Background technique [0002] Bridge guardrail is a kind of traffic safety facility installed on the outer side of the road shoulder, which prevents vehicles from going out of the road and minimizes the damage to occupants. Therefore, the application of guardrails in traffic management is particularly important. Most of the current bridge guardrails are made of concrete or metal materials, which have poor cushioning effect in the event of a collision, which is not conducive to the safety of vehicles and personnel. [0003] In the patent with publication number CN207259957U, a kind of anti-collision buffer bridge guardrail is designed, including base, column, upper beam, first connecting rod, second connecting rod, third connecting rod, movable anti-collision plate, first...
