Drum-type skew highway crash barrier

Technical Field

The utility model relates to a drum-type skew highway crash barrier.

Background

With the development of society, highways are rapidly developed. A large number of guardrails are usually arranged beside a road to enclose the road. The highway section, mountain road, etc. all need to set up the guardrail, and be to going and going lane of highway clearly separating, and, when traffic accident such as car accident takes place on the road, the guardrail can block off a part of impact, will receive the number of vehicle that reaches and reduce to minimum, and highway rail guard is the most important traffic infrastructure, and it plays important influence effect to national economy and social development. The guard rails used at present are mostly guard piles of reinforced concrete structures or the combination of steel wire protection nets and stand columns, the two guard rails lack elasticity, the buffering effect is extremely poor, and rollover and casualties are caused easily when automobiles collide.

The highway guardrail is used as an isolation boundary between a highway and the external environment and a last barrier for protecting vehicles, and plays a vital role in ensuring the driving safety of the vehicles. Particularly, in special fields such as cliffs, viaducts, winding roads, emergency turning, large-angle downhill turning and the like, the accident that the automobile is out of control to collide with the guard rail and finally the automobile is damaged and the people is killed is frequently happened. The currently used solutions are: corrugated beam steel guardrail: the application range is the widest, and the method is commonly used at the main road side, the central road side and the ramp road side. Square tube beam guardrail: the bridge is mainly used for central separation of bridges and northern snow accumulation areas, is convenient to maintain, has higher cost and is commonly used in northern areas. Flexible guardrail: the road-side. Concrete guard bar: the method is mainly used for separating the service area and the center of the ramp, and has moderate safety level, difficult maintenance and low cost. The problems existing in the prior art are as follows: the cost is high: if the square tube cross beam guardrail with high safety level is convenient to maintain, the manufacturing cost is extremely high and the guardrail is not environment-friendly. The safety level is low: for example, concrete barriers, which are mainly used for service areas and central separation of ramps, have a low cost but a low safety level, are prone to breakage and are difficult to maintain. In view of the above, the existing protective guard has the disadvantages of low cost and high safety level, and therefore, it is necessary to design a road protective guard with high buffering performance to solve such problems.

The utility model relates to a drum-type skew highway crash barrier, a serial communication port the pivot on be equipped with to the spacing plectane of cylinder post.

The utility model relates to a drum-type skew highway crash barrier, a serial communication port the support column with the body that rolls slope the installation forward, slide forward when making things convenient for the vehicle striking.

The utility model relates to a drum-type skew highway crash barrier, a serial communication port the drum post make for the rubber material.

The utility model relates to a drum-type skew highway anticollision barrier when using, builds the revetment earlier, is installing the roll body that the striking can roll and unload the power on the revetment medial surface side by side, and the pivot of roll body is passed through the support column and is fixed on the revetment, is living in the pivot of roll body and is being connected rotatable cylinder post, is equipped with convenient pivoted bearing between pivot and the cylinder post. The support column inclines the installation that inclines forward with the body that rolls, slides forward when making things convenient for the vehicle to strike.

According to the drum-type offset highway anti-collision guardrail, when an automobile is collided, the roller column rotates, the automobile slides forwards along with the roller column, the yaw effect is achieved, the course of the automobile is guided, the impact momentum of the automobile and the impact on the guardrail are reduced to the maximum extent, the safety coefficient is maximized, and therefore the impact momentum of the automobile on the guardrail is reduced.
