Description
Technical field
The utility model relates to field of traffic, is specifically related to a kind of guardrail buffer.
Background technology
Along with running at full speed of China's economy, communication have also been obtained fast development, wherein highway communication is one of topmost mode of land transportation, its flexible and rapid feature easily not only becomes an independently transportation system, also become the important means of the collecting and distributing goods and materials in railway station, harbour and airport, the economic development for country plays important basic role.Along with road construction dynamics progressively strengthens, the passenger-cargo consumption of traffic increases, road traffic accident quantity is also in rising trend, the traffic accident wherein occurring in highway corner accounts for proportion greatly, therefore mostly between margin of roads or track, all protective guard is set, but existing protective guard can not effective absorbing impact energy, easily railing is broken after causing car crass, or overturn, cause secondary collision to cause more serious accident, and all highway barriers are arranged to crashproof cushion guardail can increase great amount of cost.
Chinese patent (patent No. 20142006964.2) discloses a kind of anticollision barrier; it comprises guardrail matrix and rubber plate; the front towards direction, road surface of the coated described guardrail of described rubber plate and two end faces in described guardrail length thereof direction; achieve the seamless protection to anticollision barrier, and improve the performance preventing Snow Agent from corroding of anticollision barrier.But because this anticollision barrier only has a heavy safety precautions, buffering effect is not ideal enough; On the other hand, whole highway barrier is arranged to anticollision barrier, not only increases cost, and can the wasting of resources be caused, simultaneously due to non-dismountable between rubber plate and guardrail, be difficult to change after rubber plate corrosion is impaired.
Utility model content
For the problems referred to above, the utility model provides a kind of economical and effective, safe and practical and quick detachable removable guardrail buffer.
The utility model adopts following technical scheme:
The more than one chute that the utility model comprises hollow buffer board, be arranged on hollow buffer board front surface and the metal block be arranged in chute.
Described hollow buffer board and guardrail match, the Compress Spring that described hollow buffer board comprises the elastomeric layer being arranged on rear surface and side, the metal level being arranged on front surface and is arranged between elastomeric layer and metal level.
Described hollow buffer board is also provided with screw.
Described chute inner surface is provided with rubber spacer.
Described metal block lateral section is " L " shape, and described metal block front surface is arc, and arcwall face is relative with vehicle traveling direction, and described metal block is metal material, and arcwall face is provided with cushion rubber layer.
Described hollow buffer board height is not less than the height of guardrail.
Described elastomeric material is elastomeric material or other organic composite materials.
The beneficial effects of the utility model are as follows:
The utility model is provided with screw, is fixed on guardrail by securing member, when the utility model is damaged, can change at any time; Be provided with Compress Spring in hollow buffer board, increase hollow buffer board elasticity, car opposition of central collision can be given, reduce the instantaneous velocity of car; The utility model is provided with metal block and chute, when car and buffer collide, car with metal block along slide, the speed of a motor vehicle is decomposed to both direction, the speed of a motor vehicle is reduced, and chute inner surface is provided with cushion rubber layer, makes metal block be subject to the rightabout frictional force with the speed of a motor vehicle when sliding, reduce further the speed of a motor vehicle, thus reduce danger coefficient; Metal block surface is provided with the bed course of quality of rubber materials, can play certain cushioning effect, protection car body.The utility model only need be arranged on the guardrail of accident-prone road section, cost-saving, economical and practical, has maltilevel security safeguard measure, reduces danger coefficient to greatest extent.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is hollow buffer board sectional view.
In figure: the hollow buffer board of 1-, 2-chute, 3-metal block, 4-screw; 5-elastomeric layer, 6-metal level, 7-Compress Spring.
detailed description of the invention:
For three chutes and three metal block:
As depicted in figs. 1 and 2, the present embodiment comprise hollow buffer board 1, the chute 2 that is arranged on hollow buffer board 1 front surface and the metal block 3 be arranged on respectively in each chute 2; The number of described chute 2 and metal block 3 is respectively 3.
Described hollow buffer board 1 matches with guardrail, the Compress Spring 7 that described hollow buffer board 1 comprises the elastomeric layer 5 being arranged on rear surface and side, the metal level 6 being arranged on front surface and is arranged between elastomeric layer 5 and metal level 6.
Described hollow buffer board 1 is also provided with screw 4, for fixation hollow buffer board 1.
Described chute 2 inner surface is provided with rubber spacer, increases frictional force when metal block 3 slides.
Described metal block 3 lateral section is " L " shape, and described metal block 3 front surface is arc, and arcwall face is relative with vehicle traveling direction, and described metal block 3 is metal material, and arcwall face is provided with cushion rubber layer, for the protection of car body.
Described hollow buffer board 1 is highly not less than the height of guardrail.
Described elastomeric material is elastomeric material or other organic composite materials.
The utility model in use, first be fixed on the guardrail of both sides of highway on by screw 4 by the utility model with securing member, when there being car to hit, the Compress Spring 7 in hollow buffer board 1 is compressed, produce an opposition, the instantaneous velocity of automobile is declined, and meanwhile, automobile can slide along chute 2 along with metal block 3, the speed of a motor vehicle is decomposed to both direction, the cushion rubber layer of chute 2 inner surface is to automobile reciprocal frictional force simultaneously, reduce further the speed of a motor vehicle, reduces impact.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
