Description
Technical field
The utility model is related to guardrail fields, are a kind of safety barriers for highway specifically.
Background technology
Guardrail be it is a kind of isolation highway basic means of transportation, for prevent vehicle crash and cause casualties or other
Loss.But there are a variety of deficiencies for the guardrail under the conditions of the prior art.For example, on urban road, there is a kind of outside to be coated with black
The guardrail of Huang staggeredly is fixedly connected with the ground, and the height of itself is not high, is not connected with each other between guardrail and guardrail, is only limitted to
Limitation vehicle pass-through, due to the rigidity of guardrail itself, may aggravate the degree that is wound of vehicle body if vehicle collides with it.
Guardrail itself does not have the effect of buffering shock-absorbing, and when knocking guardrail, the kinetic energy that vehicle itself has will be totally converted
It is impact force action in the personnel in vehicle and vehicle, to cause serious safety accident.And due to this kind of guardrail height
It is smaller, there is the risk turned on one's side after knocking guardrail there is also vehicle.
Under the conditions of the prior art, there is also a kind of corrugated beam barriers, and certain buffering shock-absorbing can be played using wave beams
Effect.When errant vehicle and guardrail collide, ideally wish that guardrail can act on the active component of vehicle, both
Do not cause vehicle to run off guardrail, does not cause vehicle to pierce below guardrail cross beams yet.More satisfactory situation should pass through shield
The mass action on column forces vehicle gradually to turn to, and is returned to normal travel direction always.But the automobile produced in the world at present
Multifarious, from the heavy-duty car of large-tonnage to the minicar of very little, mass difference great disparity, vehicle external form changes very greatly.
The trend of the oriented miniaturization of car of modernization, quality becomes increasingly lighter, in order to reduce air drag, preceding car bonnet
More meet streamlined and be lower, this vehicle with guardrail when colliding, it is easy to pierce below the crossbeam of corrugated beam barrier and make
At serious consequence.
Another situation is that the tonnage of vehicle is increasing, and vehicle develops to enlargement and heavy-duty direction.Large car exists
When with rail collision, it is possible to create jump problem.Especially when bumping against with " w types " corrugated beam barrier, due to the bumper of vehicle
The cross rail top of collision waveform beam guardrail and it may be made to be twisted into for inclined-plane, such case is very big in collision angle, and speed is very high
When danger bigger, once this occurs, it is possible to make bumper downwards toward rear-inclined, under the drive of automobile impulse force
It is easy to slide onto the inclined-plane of guardrail, then runs off the accident of guardrail.
Corrugated beam barrier is often used on Pan Shang highways and highway again, once there is the accident for running off guardrail,
Vehicle is then may result in drop under mountain or enter retrograde road side and cause more serious accident.
Utility model content
The purpose of this utility model is to provide it is a kind of being capable of buffering energy-absorbing, the superior safety for highway of security performance
Guardrail.
The utility model is achieved through the following technical solutions：A kind of safety barrier for highway, including several are side by side
The protection post for being arranged and being fixedly connected with road surface, protection post outside are provided with flexible protective layer；Described is anti-
Sheath is the helical structure made of elastic plate.When because drunk driving, skidding, by other vehicle collisions situations such as appearance and
When vehicle being caused to hit guardrail from a variety of different directions, this programme can effectively be buffered from any direction using protective layer
Impact, and using itself elasticity offset vehicle part kinetic energy mitigate vehicle to reduce the impact force that vehicle is subject to
Damage situations and the injures and deaths for reducing personnel.
The protective layer is rotatablely equipped with directive wheel close to the side of highway, and the directive wheel is parallel with protection post to be set
It sets.After vehicle and guardrail collide, guiding can be played the role of using directive wheel, by guiding vehicle along guardrail
Direction is mobile and avoids vehicle that direct collision further occurs with guardrail, and plays the role of during guiding unloading power, subtracts
The speed of slow vehicle and the kinetic energy for reducing vehicle, to the impact for reducing vehicle and personnel are subject to.
The baffle for canopy-protected layer is provided on the protection post.Prevent sundries from dropping into protective layer with this
Portion, and influence the elasticity of protective layer.
The elastic cushion block that several thickness are less than or equal to spiral spacing is provided in the protective layer.It can be increased with this
The elasticity and resistance to compression, impact resistance of strong protective layer, increase the energy that protective layer can absorb.
The elastic cushion block is made of rubber.The elastic advantage high, compressibility is good that rubber has, can increase this
The elasticity of scheme entirety, and protective layer can be prevented to be compressed to the limit and lead to elastic failure.
The outer sheath of the protective layer is equipped with wear-resistant layer.Reduce vehicle after vehicle and guardrail collide with this
Friction between guardrail reduces the abrasion that vehicle external surface is subject to.
The wear-resistant layer is made of rubber.
The reflective layer of yellow is provided on the outside of the wear-resistant layer.Not dazzling yellow can be reflected using reflective layer
Light, to play the role of prompting.
It is provided on the protection post towards the bending section being bent in highway.Vehicle rollover can be prevented using bending section
To the other side of guardrail.
The elastic plate is spring steel or carbon fiber board, and the thickness of elastic plate is between 8~12mm；Described is curved
Pars convoluta is made of carbon fibre material.
The utility model compared with prior art, has the following advantages and advantageous effect：
The utility model can play the role of buffering shock-absorbing when vehicle and guardrail collide, and utilize the elasticity of itself
Offset the part kinetic energy of vehicle, the impact force that reduction vehicle and occupant are subject to, to reduce damage and the people of vehicle
The injured degree of member.
