Description
Technical field
The present invention relates to highway safe guarding device field, more particularly to a kind of anticollision public affairs on highway
Road guardrail.
Background technology
On a highway or on ordinary highway, the traffic accident that many vehicles hit guard rail can all occur every year,
The personal injury that thereby results in, vehicle and guard rail are repaired etc., not only cause economic loss, and can influence the life of household with
Work, accident can be related to the intervention of multiple departments such as traffic, medical treatment, insurance, and this accident is traffic department, insurance company, opened
Car driver, highway administration department are unwilling what is seen, how to mitigate vehicle and bump against the influence that guard rail is caused, are also the whole society
The thing of care.
The content of the invention
It is used for highway both sides it is an object of the invention to overcome the deficiencies of the prior art and provide one kind and plays buffer protection function
Anticollision highway barrier.
The purpose of the present invention is achieved through the following technical solutions：
A kind of anticollision highway barrier, the highway barrier mainly includes pedestal, supporting plate, buffer roller and for fixing
The fixing axle of buffer roller.The pedestal is fixedly installed on the ground, and its top is provided with the screwed hole for connecting.The buffering
Roller is set to cylindrical shape, which is provided with hollow bore, and the hollow bore is through to bottom always from the top of buffer roller.Institute
The two ends for stating fixing axle are provided with the external screw thread for being used for connecting.One end of the fixing axle through buffer roller hollow bore after with
Screwed hole connection on pedestal, buffer roller is secured firmly on pedestal.The supporting plate is located at the top of buffer roller, branch
The screwed hole connection on the screwed hole for connection, the other end and supporting plate of the fixing axle is again provided with fagging, makes branch
Fagging is cooperatively configured to absorb the anticollision highway barrier of impact with buffer roller, fixing axle and pedestal.
As the preferred scheme of the present invention, in order at utmost absorb the energy of shock, buffer roller of the present invention is adopted
With the softer plastic drum of material.Compared with traditional metal anticollision is rotten, this plastic drum can play buffering well and make
With the effectively injury caused by mitigation shock.
It is sliding friction as the preferred scheme of the present invention, between the buffer roller and fixing axle, under external force
It can be rotated around fixing axle.When human body or automobile are with buffer roller side collision, buffer roller Forced rotation, by part impact
Energy is laid down, and guides human body or automobile into next buffer roller, and so on, each buffer roller can therefrom absorb
A part of kinetic energy, the impact capacity produced by all collisions is finally absorbed and finished, farthest reduce the general of casualties
Rate.
As the preferred scheme of the present invention, the radius of the buffer roller is set to 250mm, is highly set to 450mm.So set
Meter is advantageous in that：On the one hand, buffer roller is contacted with vehicles or pedestrians first, most of impact energy is absorbed, so as to avoid
The metal parts of guardrail collides with vehicle or human body and damaged；On the other hand, the buffer roller of large-size can be filled out
More padded coamings, preferably absorbing impact energy are filled, while being also easier to be found by driver, so as to make rational return
Keep away.
As the preferred scheme of the present invention, in order to effectively absorb impact energy during collision, buffering of the present invention
The diameter of roller is respectively greater than pedestal and the width of supporting plate.The purpose so designed is, when a collision occurs, vehicle or people
The body buffer roller softer with material first is contacted, extruded, in extrusion process, and buffer roller can absorb part impact, subtract
The inertia of slow rammer, effectively mitigates the damage to rammer, at utmost ensures the life security of rammer.
Further, in order to further mitigate the injury caused by shock, the side of buffer roller of the present invention is also
Provided with the sponge wrapping layer for apparatus with shock absorbing.Sponge wrapping layer is first with vehicle or human contact and absorbing part energy
Amount, in addition, its soft texture is damaged when can avoid colliding.It is preferred that, the sponge wrapping layer can also be used
Froth bed is replaced.
Further, in order to further mitigate the injury caused by shock, the inside of buffer roller of the present invention
Also fill up the sponge packed layer for apparatus with shock absorbing.
Further, in order to remind driver at night on the run note both sides road and things, the sponge
Reflector layer is additionally provided with the outside of integument, the reflector layer is pasted onto the outside of sponge wrapping layer, under light-illuminating.
Working process and principle of the invention are：During installation, pedestal is fixed on to the both sides of highway first, then will be fixed
Axle is connected with the screwed hole on pedestal, then penetrates buffer roller in fixing axle, is finally arranged on supporting plate and fixes
On axle, it is connected by screw thread with fixing axle；When colliding, the sponge wrapping layer on buffer roller is contacted with automobile first,
Absorb a part of kinetic energy and prevent that vehicle body from being scraped, then buffer roller can be rotated with the direction of running car naturally,
Most of impact energy is absorbed crimp and by way of changing collision force direction, property and life is at utmost ensure that
Safety.The present invention also has the advantages that simple in construction, easy for installation, readily replaceable.
Compared with prior art, the present invention has further the advantage that：
(1) anticollision highway barrier provided by the present invention uses the plastic. buffer roller compared with softwood matter instead of traditional
Guardrail wires, can mitigate the injury that collision is caused, effectively reduce the loss caused by collision.
(2) anticollision highway barrier provided by the present invention sets one layer of sponge wrapping layer in the side of buffer roller,
The impact produced by hitting can be further absorbed, the inertia hit is reduced, and sponge material is soft, and human body will not be produced
Secondary injury.
(3) anticollision highway barrier provided by the present invention is provided with packed layer in buffer roller, further absorbs
Kinetic energy produced by impact, reduces casualties and property loss caused when accident occurs, effectively improves traffic accident
Survival probability.
(4) contacted between buffer roller provided by the present invention and fixing axle using sliding friction, occurring side collision
When can shed part impact kinetic energy well, and be directed to next buffer roller and absorb impact again, finally until hitting institute
The kinetic energy of generation is absorbed completely, and the situation for farthest reducing casualties occurs.
(5) anticollision highway barrier provided by the present invention uses the buffer roller of large-size, and in buffering rolling
Reflector layer is posted on the surface of cylinder, makes driver at night also it is easy to note that the generation of traffic accident can be reduced.
(6) buffer roller provided by the present invention is fixed by fixing axle with pedestal and supporting plate, readily replaceable and maintenance.
(7) present invention can afforest flowers and plants, not only attractive in appearance but also environmental protection in the top plantation of supporting plate.
