Description

Guardrail capable of retarding front impact

Technical Field

The invention relates to a guardrail for slowing down frontal impact, in particular to a guardrail adopting a special structure, which can effectively prevent the frontal direct impact of an automobile and belongs to the field of traffic.

Background

At present, a lot of traffic accidents make people lose relatives, a lot of traffic accidents are all related to guardrails, the guardrails can avoid a part of traffic accidents, but at the same time, some accidents caused by the guardrails also exist, vehicles with some accidents directly hit the top of the guardrail due to improper driving, the vehicles directly hit the top because the guardrails are fixed on the ground, huge impact force can directly tear the vehicles into two halves, although the initial parts of some guardrails are bent outwards to avoid the situation, the effect is not ideal, the guardrail in the center of the road has no way to adopt the structure, and hidden dangers still exist.

Disclosure of Invention

In view of the above disadvantages, the present invention provides a guardrail with front impact mitigation, which can mitigate impact force and avoid accidents for vehicles that may directly hit the top end of the guardrail.

The invention is realized by the following technical scheme: a guardrail for slowing down the front impact comprises an anti-collision plate, supporting rods, hexagonal fixing frames, stand columns, springs, a front baffle, a rear baffle, guardrail plates, sleeves, a ground rail sliding block, a ground rail spring and ground piles, wherein the inner side of the anti-collision plate is fixedly connected with a plurality of cylindrical supporting rods of which the middle belts are fixedly connected with the front baffle, the supporting rod at the front end of the front baffle penetrates through one hexagonal fixing frame, the rear end of the supporting rod sequentially penetrates through the rear baffle with holes, the springs are arranged between the front baffle and the rear baffle on the supporting rod, the stand columns with ribs are fixedly connected inside the hexagonal fixing frame, the guardrail plates are fixed on two sides of the hexagonal fixing frame, the ground rail is arranged at the lower end of the first stand column, the ground rail sliding block fixedly connected to the stand columns is arranged in the ground rail, the ground rail spring is arranged inside the ground rail sliding block and at the rear side of the ground rail sliding block, the ground piles with long conical threads are fixedly connected below the stand columns from, the rear end of the sleeve is fixedly connected to the hexagonal fixing frame.

The anti-collision plate is C-shaped with a flat middle and two bent ends, and the thickness of the anti-collision plate is 0.3-2.5 cm.

The quantity of bracing piece be 1~5, vertical cross-section is the atress uniformity and describes the range, all installs a spring and a preceding baffle on every bracing piece, the quantity and the position of the hole on hexagonal mount and the backplate correspond with the quantity and the position of bracing piece, the diameter in hole is 1~2mm bigger than the diameter of bracing piece.

The number of the sleeves is the same as that of the support rods, and the diameter of the hole in each sleeve is 1-2 mm larger than that of each support rod.

The ground rail and the ground pile are both positioned below the ground.

The length of the sleeve is greater than the horizontal length from the anti-collision plate to the rear end of the ground rail.

The anti-collision device has the beneficial effects that when the front of a vehicle directly collides with the top end of the guardrail, the front of the vehicle directly contacts with the anti-collision plate, the anti-collision plate pushes against the supporting rod to move backwards, a reverse force is generated to offset a part of collision force due to the action of the spring and the rear baffle plate, if the vehicle speed is too high, the anti-collision plate enters the buffer of the second part and pushes against the first upright post to drive the first upright post to move backwards, so that the spring is further compressed and the ground rail spring is compressed to form secondary buffer, and the collided vehicle can be greatly reduced through the two-time buffer, so that the accident caused by the tearing of the vehicle body is avoided.
