Abstract

The utility model discloses a kind of curve guard rail cushion at collision, fixed plate including being fixedly connected on buffer rear body, the front of the buffer ontology is fixedly connected with buffer layer, the bottom of the buffer ontology is fixedly connected with the baffle being vertically arranged, the buffer layer constitutes step structure by the first buffer stages, the second buffer stages and third buffer stages are successively continuously coupled from top to bottom, and extends at baffle and be fixedly connected.The utility model can effectively absorb vehicle crash power by the staged buffer layer of setting, it ensure that under the conditions of certain speed vehicle can mitigate the rigid collision dynamics with guardrail, the problem of so as to avoid vehicle rollover, while this kind of buffer is easy for installation, it is practical and efficient.

Description

A kind of curve guard rail cushion at collision
Technical field
The utility model relates to highway guardrail technical field, specially a kind of curve guard rail cushion at collision.
Background technique
Highway guardrail is applied to always fastlink as a kind of effective safety protecting device for travelling crane, but due to There are many section situations for fastlink, and every kind of section situation will be different, and existing fastlink is in ramp segment Usually it can lead to not in time vehicle rollover because of the processing of bend vehicle, and often due to car body itself can be produced with guardrail before rollover Caused by raw rigid collision, how to avoid the vehicle as caused by the particularity of bend position in vehicle deceleration process unexpected Collision situation is at relevant design personnel's problem to be solved.
Utility model content
The purpose of this utility model is to provide a kind of curve guard rail cushion at collision, to solve to mention in above-mentioned background technique Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of curve guard rail cushion at collision, including It is fixedly connected on the fixed plate of buffer rear body, the front of the buffer ontology is fixedly connected with buffer layer, described slow The bottom for rushing device ontology is fixedly connected with the baffle being vertically arranged, and the buffer layer is by the first buffer stages, the second buffer stages With third buffer stages from top to bottom successively continuously coupled composition step structure, and extends at baffle and be fixedly connected.
First buffer stages, the second buffer stages and third buffer stages are the cambered surface of the obstructed over-angle setting of tool Structure, the cambered surface angle of first buffer stages are 60 ° -75 °, and the cambered surface angle of second buffer stages is 45 ° -60 °, The cambered surface angle of the third buffer stages is 30 ° -45 °.
The height of the buffer ontology is 1m, with a thickness of 50cm-70cm.
The buffer ontology is high-density sponge material.
The buffer layer and baffle are rubber material.
As shown from the above technical solution, the utility model can effectively absorb vehicle by the staged buffer layer of setting Impulsive contact force ensure that under the conditions of certain speed vehicle can mitigate the rigid collision dynamics with guardrail, so as to avoid vehicle side The probability turned over, while this kind of buffer is easy for installation, it is practical and efficient.
Detailed description of the invention
Fig. 1 is the utility model side sectional view;
Fig. 2 is the utility model structure diagram;
Fig. 3 is the utility model scheme of installation.
In figure: 1 buffer ontology, 2 fixed plates, 3 bolts, 4 guardrails, 5 buffer layers, 51 first buffer stages, 52 second are delayed Rush stratum, 53 third buffer stages, 6 baffles.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
A kind of curve guard rail cushion at collision as shown in Figs. 1-3, including being fixedly connected on consolidating for 1 rear portion of buffer ontology Fixed board 2, the front of the buffer ontology 1 are fixedly connected with buffer layer 5, and the bottom of the buffer ontology 1 is fixedly connected with The baffle 6 being vertically arranged, the buffer layer 5 by the first buffer stages 51, the second buffer stages 52 and third buffer stages 53 by The successively continuously coupled composition step structure under, and extend at baffle 6 and be fixedly connected, this kind of buffer leads to during installation It crosses fixed plate 2 to be connected on guardrail 4, and the bolt 3 by being arranged in fixed plate 2 is fixed and is connected on guardrail 4, institute State the cambered surface knot that the first buffer stages 51, the second buffer stages 52 and third buffer stages 53 are the obstructed over-angle setting of tool Structure, the cambered surface angles of first buffer stages 51 are 60 ° -75 °, the cambered surface angle of second buffer stages 52 is 45 ° - 60 °, the cambered surface angle of the third buffer stages 53 is 30 ° -45 °, this kind of staged angle setting can effectively agree with vehicle The position of headstock part, during vehicular impact, the headstock of different height position can impact in different buffer stages, and And huge damage caused by capable of effectively reducing in rigid collision, the setting of angle equally can make vehicle headstock position exist The buffer stages that can be gradually reduced along the gradient in impact process are collided, and effective buffering effect is played.
Further, the height of the buffer ontology 1 is 1m, and with a thickness of 50cm-70cm, this kind of height can be effective It is adapted to the position height of headstock, suitable for the impact at a variety of vehicle headstock positions, while thickness is moderate, is not blocking curve traffic More preferably safe effect is provided in the case where the visual field.
Further, the buffer ontology 1 is high-density sponge material, and high-density sponge can effectively be born vehicle wink Between huge impulsive contact force.
Further, the buffer layer 5 and baffle 6 are rubber material.
This kind of buffer is easy for installation, can successively be fixedly mounted around 4 place curved edge of guardrail during the installation process, And buffer ontology 1 is arranged towards road surface direction, and after colliding, the replaceable installation of this kind of buffer, using flexible It is convenient.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines In range.
