Referring to fig. 1 to 2, the embodiment of the present application provides a leaf spring type crash barrier, which includes an elastic rail 100, the elastic rail 100 includes an arc-shaped buffering portion 101 and an energy releasing portion 102, a convex side of the arc-shaped buffering portion 101 faces a road, the energy releasing portion 102 is disposed in a concave side of the arc-shaped buffering portion 101, and the arc-shaped buffering portion 101 is provided with a plurality of rotatable guide drums 200 along an arc surface thereof.

Specifically, in the present embodiment, as shown in fig. 1 and fig. 2, the arched buffering portion 101 and the energy releasing portion 102 are the same spring leaf, wherein the arched buffering portion 101 is disposed in front of the arched buffering portion to form an arched arc surface, and two ends of the arched buffering portion 101 are spirally wound into a plurality of turns of spring leaf structures respectively and disposed on the concave side of the arched arc surface of the arched buffering portion 101 to form the energy releasing portion 102, and in the energy releasing portion 102, a gap is left between two adjacent turns of spring leaf structures, so as to form an energy absorbing cavity by using the gap. It can be expected that when a vehicle is collided with an anti-collision guardrail by deviating from a road surface, because the spring structures of the plurality of rings have good elasticity, the spring pieces are large in size and form an energy absorption cavity, after the elastic anti-collision guardrail is collided, the elastic railing 100 deforms to consume collision energy, and huge impact force caused by vehicle collision can be buffered, so that the safety of people and vehicles is protected, the collision is relieved, and the damage of the vehicles and the people is reduced.

In the present embodiment, in order to adjust the traveling direction of the collided vehicle, referring to fig. 1 to 2, a plurality of installation cavities are arranged at intervals along the arc surface of the arched buffer part 101, a rotating shaft 600 is vertically installed in each installation cavity, one guide drum 200 is sleeved on each rotating shaft 600, and the guide drums 200 freely rotate on the rotating shafts 600. It is foreseeable that when the arc-shaped buffer part 101 contacts with the vehicle body, the contact surface between the arc-shaped buffer part 101 and the vehicle is larger, after the vehicle is impacted, the arc-shaped buffer part is flatly unfolded towards two sides along the elastic guardrail, the running direction of the vehicle is changed, the vehicle slides on the guardrail along a plurality of continuous guide drums 200, and the running direction of the vehicle is orderly adjusted until the vehicle is in the same direction with the guardrail or the road surface, so that the vehicle is prevented from rushing out of the road surface.

In one embodiment, in order to stably install the elastic balustrade 100 on the road surface 700, referring to fig. 1 to 2, the energy releasing portion 102 is coiled by a spring plate to form a sleeve hole, a column 300 is inserted into the sleeve hole, and meanwhile, an upper cross beam 400 and a lower cross beam 500 are respectively disposed at the upper end and the lower end of the elastic balustrade 100, the upper end and the lower end of the column 300 respectively penetrate through the upper cross beam 400 and the lower cross beam 500, and the upper cross beam 400 and the lower cross beam 500 are fixed to the column 300, so that the elastic balustrade 100 is clamped and limited by the upper cross beam 400 and the lower cross beam 500, and the column 300 is nailed into the road surface, so that the elastic balustrade 100 is well fixed on the road surface 700.

In one embodiment, in order to provide a striking prompt for the driver, the guide drum 200 is coated with a striking color, and the guide drum is also provided with a reflective sign, wherein the predictable striking color and the reflective sign arranged on the guide drum 200 can improve the identification of the road and provide a more striking warning for the driver at night.

To sum up, the spring leaf formula crash barrier that this application embodiment provided has following advantage:

firstly, the method comprises the following steps: the spring leaf formula anticollision barrier that this application embodiment provided, because elasticity railing 100 self adopts the spring leaf as the main part, form arch buffer portion 101 and the energy release portion 102 that many rings of layer spring coils and form, utilize the spring structure to have good elasticity, form the energy-absorbing chamber through spring leaf massiveness, can consume the impact energy when elasticity railing 100 takes place to deform, can cushion a large amount of vehicle impact force, protect people, car safety, alleviate the striking, reduce car and people's damage.

Secondly, the method comprises the following steps: the embodiment of the application provides a spring leaf formula anticollision barrier, because elasticity railing 100 has arch buffer 101, when the vehicle takes place the striking with arch buffer 101, based on the cambered surface of arch buffer 101, make area of contact when vehicle and guardrail collide for ordinary plane, the contact surface of cambered surface is bigger, receive the striking back, elasticity railing 100 is levelly and smoothly expanded to the guardrail both sides, change the vehicle direction of travel, the vehicle slides on a plurality of continuous direction rotary drums 200 on the guardrail, the direction of travel of adjustment vehicle is up to with guardrail or road surface syntropy in order.

Thirdly, the method comprises the following steps: the spring leaf formula anticollision barrier that this application embodiment provided because direction rotary drum 200 is solid construction, avoids in-service use direction rotary drum 200 to lead to the light collision because of hollow easily to be damaged, and the condition that needs frequent change takes place.

Fourthly: the guide drum 200 has striking colors and is provided with a light reflecting mark, so that the identification degree of a road can be improved, and a driver can be warned more striking at night.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
