Abstract
The invention discloses a kind of anticollision barrier, arrange outer by PE on cemented body surface and be filled in the crashproof cushion pad that in PE skin, PU foaming body internal layer forms, can, to automobile start cushioning effect of coming as rollover, collision out of control, avoid rigid collision to cemented body causes damage to automobile itself, occupant and car stranger or thing; Meanwhile, crashproof cushion pad is upper and lower is respectively equipped with hemispheric projection and lower convexity, and during wheel rollover, wheel side tyre surface contacts with lower convexity with projection, has large cushion space, good buffer effect; In addition, the 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 is contrary with rotation of wheel direction, can slow down vehicle wheel rotational speeds, effectively reduce injury.
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 being located thereon portion, and protected apron is made up of steel plate, and both are for rigid material is also in being rigidly connected.After take charge knocks protected apron, protector can stop automobile plough under the dewatering ditch of speedway both sides of highway or pour the dangerous situation generation of opposing lane collision.But facts have proved that the protected apron of said structure is without pooling feature, under the impact force that automobile high-speed out of control is powerful, protected apron often can be caused to break, automobile out of control pours opposing lane and collides, and causes car crash; Especially the protected apron broken is hurted sb.'s feelings even more serious, can not effectively stop automobile plough under the dewatering ditch of speedway both sides of highway or pour the danger generation of opposing lane collision.On the other hand, the protected apron be made up of steel plate is also thoroughly raw, and lose compressive resistance and anti-collision effect, 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, carries out cushion bumper by arranging cushion pad to automobile out of control.
Anticollision barrier of the present invention, comprises Cement guard bar body, and described body height is suitable with wheel height, and the one side on body inside highway is provided with crashproof cushion pad, and described cushion pad is primarily of PE skin and be filled in PU foaming body internal layer composition in PE skin.
Further, in the middle part of described crashproof cushion pad, be provided with hemispherical projections, wheel and this projection contacts during vehicle side turning.
Further, described projection is divided into projection and lower convexity, and during vehicle side turning, the side tyre surface of wheel contacts with lower convexity with described projection.
Further, to compare the length that projection extends in highway long for the described lower convexity length extended in highway.
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 is contrary with rotation of wheel direction.
Further, described crashproof cushion pad top extends to outside body from body end face.
Beneficial effect of the present invention:
1) arrange outer by PE on cemented body surface and be filled in the crashproof cushion pad that in PE skin, PU foaming body internal layer forms, can, to automobile start cushioning effect of coming as rollover, collision out of control, avoid rigid collision to cemented body causes damage to automobile itself, occupant and car stranger or thing;
2) crashproof cushion pad is upper and lower is respectively equipped with hemispheric projection and lower convexity, and during 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 is contrary with rotation of wheel direction, can slow down vehicle wheel rotational speeds, effectively reduce injury.
Accompanying drawing explanation
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, the one side of body 1 inside highway is provided with crashproof cushion pad 2, described crashproof cushion pad is fixed on body 1 by crab-bolt, when automobile occur out of control hit guardrail time, 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 PE outer 21 and the PU foaming body internal layer 22 be filled in PE skin, and PU foaming body internal layer energy-absorbing effect is good, and cushioning effect is more obvious.
embodiment 2
The basis of embodiment 1 is improved further, crashproof cushion pad is provided with hemispherical projections 3, during vehicle side turning, first wheel contacts with protruding 3, protruding concrete larger cushion space.
embodiment 3
On the basis of embodiment 1, projection 4 and lower convexity 5 is divided into protruding 3, during 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 can strengthen buffering effect with side tyre surface.
As the further improvement of top technical scheme, it is long that described lower convexity 5 length extended in highway compares the length that projection 4 extends in highway, during vehicle side turning, wheel bottom first touches crashproof cushion pad, rollover angle can be reduced, car body is put on right position faster, the buffering effect improved further.
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 is contrary with rotation of wheel direction, vehicle wheel rotational speeds can be slowed down, 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 outside body from body end face, and namely crashproof cushion pad can cover bodies top, can reduce goods that junk falls as boxcar to the damage of guardrail.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
