Description

Multifunctional anti-collision guardrail

Technical Field

The utility model belongs to the technical field of highway guardrail protection, and particularly relates to a guardrail.

Background

The anti-collision guardrail belongs to a very key traffic facility, is not only favorable for the maintenance of a highway, but also favorable for providing safety guarantee for vehicles running on the highway, and bears the important role of guaranteeing the life safety of people. The anti-collision guardrail plays the role of isolation and protection when the highway normally operates. When the vehicle collides with the guardrail, the guardrail is required to have good collision resistance and an energy absorption function, and the vehicle and drivers and passengers are well protected.

Current guardrail adopts single tube crossbeam mostly, and this crossbeam is receiving the vehicle striking, and its stress point is yielding to take place sunken, and the resistance is too big to lead to the vehicle not good at the guidance quality.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a multifunctional anti-collision guardrail which is high in strength, not easy to deform when being impacted by a vehicle, and good in collision resistance and energy absorption.

The technical scheme of the utility model is as follows: the guardrail comprises at least one guardrail unit, wherein the guardrail units are sequentially connected end to form a guardrail body; the guardrail unit is formed by sequentially connecting a plurality of sections of guardrail sections end to end; the guardrail section comprises a base positioned at the bottom and two cross beams arranged on the base through upright posts, wherein the two cross beams extend along the length direction of the guardrail and are arranged in parallel; the guardrail sections comprise movable sections and/or fixed sections.

There are two support columns stand upper end, and in a support column stretched into the mounting hole in a crossbeam, another support column stretched into the mounting hole that corresponds in another crossbeam, the stand outside of support column root department was equipped with the extension board, and it has the pilot hole that is used for cartridge connecting piece to connect the crossbeam to open on the extension board.

And a mounting groove is formed in a gap between the two support columns. The inner surfaces of the two beams are oppositely arranged in the mounting groove.

The base is a box body, the longitudinal section of the box body is trapezoidal, the box body comprises an upper plane, a lower plane, a left inclined plane and a right inclined plane, the upper plane and the lower plane are parallel to each other, and an inner lining plate parallel to the upper plane is arranged in the box body.

The inner lining plate is arranged close to the upper plane.

When the guardrail section in a guardrail unit comprises at least one movable section and two fixed sections, the movable section is positioned between the two fixed sections.

The lower part of the movable base of the movable section is a roller, and the lower part of the fixed base of the fixed section is fixed on the ground through an anchor bolt.

Compared with a single-tube beam, on the premise of the same sectional area, the double-tube beam is high in strength, the problem that stress points are easy to deform and sink can be solved, the stress position of the beam forms an arc-shaped collision surface, vehicles can be smoothly guided out during collision, the safety of vehicle personnel is kept from the surface, and the death rate of drivers and passengers is greatly reduced.

Detailed Description

In fig. 1-5, a plurality of movable segments 92 are positioned between two fixed segments 91 to form a guardrail. The lower part of the movable base 3 of the movable section 92 is a roller, and the lower part of the fixed base 4 of the fixed section 91 is fixed on the ground through an anchor bolt 6. The movable base 3 is provided with two beams 1 arranged in parallel through the upright post 5, the two beams 1 are a first beam 11 and a second beam 12, and a small gap is formed between the first beam 11 and the second beam 12. Two crossbeams 2 that the unable adjustment base 4 upper portion was installed through stand 5 and is set up side by side, and two crossbeams 2 are crossbeam three 21, crossbeam four 22, have the little clearance between crossbeam three 21, the crossbeam four 22. The movable base 3 and the fixed base 4 are a box body, the longitudinal section of the box body is trapezoidal, the box body comprises an upper plane, a lower plane, a left inclined plane and a right inclined plane, the upper plane and the lower plane are mutually parallel, and an inner lining plate 8 parallel to the upper plane is arranged in the box body. The existing guardrail adopts the lining plates with vertical intervals, and when the guardrail is impacted by force, concave surfaces can be formed at the positions without the lining plates, so that the advance of vehicle tires is seriously influenced and hindered. In severe cases, the tail flicking of the vehicle is affected, and a secondary accident of the vehicle is caused. Aiming at the situation, the base of the guardrail is a box body, and the lining plate 8 parallel to the upper plane of the box body is adopted in the box body, so that the defect of a concave surface is solved, and the protective effect of the guardrail is better.

In fig. 6 and 7, two support columns 51 are arranged at the upper end of the upright column 5, one support column extends into a mounting hole in one cross beam, the other support column extends into a corresponding mounting hole in the other cross beam, a support plate 53 is arranged on the outer side of the upright column at the root of the support column, and an assembly hole 54 for connecting the cross beam by a plug-in connecting piece is formed in the support plate.
