Description

Traffic guardrail capable of buffering energy absorption

Technical Field

The utility model belongs to the technical field of traffic facilities, concretely relates to can cushion traffic guardrail of energy-absorbing.

Background

As a transportation means, the automobile brings convenience to users, but automobile accidents frequently occur, so that the safety of lives and property is threatened. In order to minimize the occurrence of accidents and to reduce the consequences of accidents, it is common to provide protective barriers at the road side or in the middle of the road, such as concrete railings fixed to the road, or made up of concrete blocks arranged at intervals and rails connecting adjacent blocks. When an automobile collides with the protective guard, the automobile can be prevented from crossing a middle line to enter a facing opposite lane and colliding, however, the existing protective guard cannot absorb impact force, and under the reverse acting force of the protective guard during collision, the automobile overturns or reverses and deviates from an original lane and generates secondary collision with an adjacent lane or a roadside, so that the harm degree is increased. After an accident occurs, when the damaged protective fence is repaired, the repairing work is troublesome, the duration is long, the repairing cost is high, and the normal operation of a road is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to above-mentioned defect, provide a can cushion the traffic guardrail that absorbs energy, can absorb the impact effectively, prevent that the car from taking place secondary collision.

The utility model provides a technical scheme that its technical problem adopted as follows:

a traffic guardrail capable of buffering energy absorption comprises a pillar and a cross rod arranged on the pillar; the cross bar comprises two symmetrically-arranged sectional materials, each sectional material comprises an arc-shaped plate, folded edges are formed at two opposite ends of each arc-shaped plate, and the bending direction of each folded edge is opposite to that of each arc-shaped plate.

Further, the quantity of horizontal pole is equipped with a plurality ofly, and a plurality of horizontal poles are along the axial equidistance setting of stand.

Furthermore, a positioning block for connecting the sectional materials is arranged on the support column, and the positioning block and the support column are of an integrated structure.

Furthermore, the two ends of the two sectional materials are mutually attached, and the middle parts of the two sectional materials form an energy absorption space.

Furthermore, the section bar is connected with the positioning block through a fastener, and a plurality of fastening holes for mounting the fastener are formed in the surface of the middle of the section bar.

Further, the folded edge is circular or mosquito-repellent.

Further, the thickness of the section bar is 1-2 mm.

The utility model has the advantages that:

(1) the middle cross bar of the utility model is composed of two sectional materials, which is convenient for transportation; when in replacement, the replacement can be carried out independently, thus saving the cost; the section bar adopts a structure of an arc-shaped plate and folded edges arranged at two opposite ends of the arc-shaped plate, so that the crushing damage of an automobile caused by impact can be reduced, and a good energy absorption effect is achieved, thereby achieving the effect of protecting the impacting objects; the buffer structure has a buffer function, can avoid the damage of the passing-through secondary collision of the vehicle, has the stress relief function in the same direction when the vehicle is collided, and cannot pierce the vehicle body when the vehicle is collided, thereby avoiding the damage to drivers and passengers; the utility model discloses the structure is retrencied, reasonable in design.

(2) The utility model discloses the quantity of well horizontal pole can increase and decrease according to actual conditions to guarantee the best protective effect.

(3) The utility model discloses an adopt the locating hole to link to each other with the section bar, the installation is firm, easy dismounting.

(4) The utility model discloses well two section bar compact structure can cushion and the energy-absorbing effectively through the energy-absorbing space to guarantee driver and crew's safety in the at utmost.

(5) The utility model discloses this side of well ring type and mosquito-repellent incense type has good energy-absorbing effect and structural strength, can play the guard action to driver and crew after the vehicle striking.

(6) The utility model discloses well section bar passes through the fastener with the locating hole and links to each other, firm in connection, and the dismouting is maintained conveniently.

Drawings

The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a left side view of FIG. 1;

wherein: pillar 1, horizontal pole 2, section bar 21, arc 211, hem 212, locating piece 3, fastener 4.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, the traffic guardrail capable of buffering energy absorption comprises a support column 1 and cross rods 2 arranged on the support column 1, wherein the number of the cross rods 2 is multiple, the number of the cross rods 2 is three in the embodiment, and the three cross rods 2 are arranged at equal intervals along the axial direction of a vertical column 1. The cross bar 2 comprises two symmetrically arranged section bars 21, and the thickness of the section bars 21 is 1-2mm, so that the cross bar is light in weight and convenient to carry and transport. The positioning block 3 for connecting the section bar 21 is arranged on the pillar 1, the positioning block 3 and the pillar 1 are of an integral structure, the section bar 21 is connected with the positioning block 3 through a fastening piece 4, the fastening piece 4 in the embodiment adopts a screw, and a plurality of fastening holes for installing the fastening piece are arranged on the surface of the middle part of the section bar 21. The profile 21 comprises an arc plate 211, and two opposite ends of the arc plate 211 are formed with folded edges 212, and the bent direction of the folded edges 212 is opposite to the bent direction of the arc plate 211. When the crossbar 2 is assembled, the two ends of the two profiles 21 are attached to each other, for example, the folded edges 212 of the two profiles 21 are attached to each other, the middle portions of the two profiles 21 form an energy absorbing space, the folded edges 212 are circular or mosquito-repellent, preferably circular in this embodiment, and it is noted that the circular folded plates are not closed so as to absorb energy. The plane that the top of the middle part of section bar was located is higher than the plane that the top of hem was located, and during the installation, the middle part of section bar contacted with the locating piece, and the appearance is pleasing to the eye like this, and whole compactness is retrencied, and structural strength is high.

The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
