Abstract
The invention discloses an anti-collision guardrail. An anti-collision buffering pad is arranged on the surface of a cement body and is provided with a PE outer layer and a PU foaming body inner layer, wherein the PE outer layer is filled with the PU foaming body inner layer. The anti-collision buffering pad has a buffering function on vehicles out of control, such as rollover vehicles and collided vehicles, and prevents the situation that the vehicles collide with the cement body in a rigid mode and the vehicles, people in the vehicles and people or objects out of the vehicles are damaged and hurt. Meanwhile, the upper portion and the lower portion of the anti-buffering pad are provided with a semispherical upper protrusion and a semispherical lower protrusion respectively, side tire faces of wheels of vehicles are in contact with the upper protrusion and the lower protrusion when the wheels roll over, a large buffering space is available, and the buffering effect is good. Besides, the surface of the upper protrusion and the surface of the lower protrusion of the anti-buffering pad are provided with friction strips which are distributed in a spiral mode, the rotation direction of the friction strips is opposite to that of the wheels, and accordingly rotation speed of the wheels can be reduced and damage is effectively reduced.
Description
Technical field
The present invention relates to highway facilities field, particularly a kind of anticollision barrier with pooling feature.
Background technology
At present, the protector of speedway both sides of highway is made up of column and the protected apron that is located thereon portion, and protected apron is made up of steel plate, and both are also and are rigidly connected for rigid material.When take charge knocks after protected apron, protector can stop automobile to plough under the dewatering ditch of speedway both sides of highway or pour the dangerous situation generation of colliding in track, opposite.But facts have proved that the protected apron of said structure is without pooling feature, under the powerful impact force of automobile high-speed out of control, often can cause protected apron to break, automobile out of control pours track, opposite and collides, and causes car crash; Especially the protected apron breaking is hurted sb.'s feelings even more serious, can not effectively stop automobile to plough under the dewatering ditch of speedway both sides of highway or pour the danger of colliding in track, opposite to occur.On the other hand, the protected apron of being made up of steel plate is also thoroughly raw, loses compressive resistance and crashproof effect, and application life is shorter.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of anticollision barrier, by cushion pad is set, automobile out of control is carried out to cushion bumper.
Anticollision barrier of the present invention, comprises Cement guard bar body, and described body height is suitable with wheel height, and the one side near highway inner side on body is provided with crashproof cushion pad, and described cushion pad is mainly outer by PE and be filled in PU foaming body internal layer in PE skin and form.
Further, described crashproof cushion pad middle part is provided with hemispherical projections, and when vehicle side turning, wheel contacts with this projection.
Further, described projection is divided into projection and lower convexity, and when vehicle side turning, the side tyre surface of wheel contacts with lower convexity with described projection.
Further, described lower convexity extends to length in highway and compares projection to extend to length in highway long.
Further, the surface of described crashproof cushion pad projection and lower convexity is provided with fricting strip, and described fricting strip becomes spiral line type to arrange, and rotation direction and rotation of wheel opposite direction.
Further, described crashproof cushion pad top extends to body outside from body end face.
Beneficial effect of the present invention:
1) outer and be filled in the crashproof cushion pad that in PE skin, PU foaming body internal layer forms by PE in the setting of cement body surface, the automobile start cushioning effect that can come to out of control as rollover, collision, avoids rigid collision, to cement body, automobile itself, occupant and car stranger or thing are caused to damage;
2) upper and lower hemispheric projection and the lower convexity of being respectively equipped with of crashproof cushion pad, when wheel rollover, wheel tyre surface contacts with lower convexity with projection, has large cushion space, good buffer effect;
3) surface of crashproof cushion pad projection and lower convexity is provided with fricting strip, and fricting strip becomes spiral line type to arrange, and rotation direction and rotation of wheel opposite direction, can slow down rotation of wheel speed, effectively reduces injury.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Fig. 3 is the structural representation of embodiment 3;
Fig. 4 is the left view of Fig. 3.
Detailed description of the invention
embodiment 1
Comprise Cement guard bar body 1, described body height is suitable with wheel height, body 1 is provided with crashproof cushion pad 2 near the one side of highway inner side, described crashproof cushion pad is fixed on body 1 by crab-bolt, when automobile occurs out of control while hitting guardrail, first automobile contacts crashproof cushion pad, and crashproof cushion pad produces cushioning effect to automobile, avoids automobile and column guardrail body rigid collision.Described cushion pad is made up of with the PU foaming body internal layer 22 being filled in PE skin PE outer 21, and PU foaming body internal layer energy-absorbing effect is good, and cushioning effect is more obvious.
embodiment 2
On the basis of embodiment 1, further improve, be provided with hemispherical projections 3 on crashproof cushion pad, when vehicle side turning, first wheel contacts with projection 3, the concrete larger cushion space of projection.
embodiment 3
On the basis of embodiment 1, projection 3 is divided into projection 4 and lower convexity 5, when vehicle side turning, wheel tyre surface contacts with lower convexity 5 with described projection 4, and the side tyre surface relative wheel wheel hub of wheel is more coarse, and upper and lower projection contacts and can strengthen buffering effect with side tyre surface.
As the further improvement of top technical scheme, described lower convexity 5 extends to length in highway and compares projection 4 to extend to length in highway long, when vehicle side turning, wheel bottom first touches crashproof cushion pad, can reduce rollover angle, car body is put on right position faster, the buffering effect further improving.
As the further improvement of top technical scheme, the surface of described crashproof cushion pad projection and lower convexity is provided with fricting strip 6, described fricting strip becomes spiral line type to arrange, and rotation direction and rotation of wheel opposite direction, can slow down rotation of wheel speed, slow down automobile preshoot momentum, avoid or reduce clashing into injury.
Finally, the crashproof cushion pad top in embodiment 1-3 all can extend to body outside from body end face, and crashproof cushion pad can cover bodies top, can reduce the damage to guardrail of goods that junk falls as boxcar.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
