Embodiment 1
As shown in Figure 1 to Figure 3, compact road traffic safety guard of the invention, including column 100, elastic rotary portion
Part 200 and horizontal bar, horizontal bar include some horizontal bar units 300, and horizontal bar unit 300 includes the first horizontal bar body 310, the second horizontal bar sheet
The horizontal bar body 330 of body 320 and the 3rd, wherein the first horizontal bar body 310 and the 3rd horizontal bar body 330 are isometric, the first horizontal bar body
310 or the one end of the 3rd horizontal bar body 330 be fixed on column 100, the other end is rotated with reference to elastic rotary part 200 and with second
Horizontal bar body 320 is fixed.
Inventor is by largely testing and Structure Improvement Design, by horizontal bar shortening, the first horizontal bar body 310 or the 3rd
The one end of horizontal bar body 330 is fixed on column 100, the other end rotate with reference to elastic rotary part 200 and with the second horizontal bar body
320 fix what deserves to be explained is, bonding strength between horizontal bar 300 and column 100 is high, even if during Vehicular impact, can also protect
Card vehicle will not cross guardrail, while simplify installation process, only need one to two people to complete the installation of horizontal bar, operating personnel
Number is few；In addition so that road traffic guardrail installation is more convenient, in Process of Engineering Construction, traffic guardrail can be greatly shortened
Set-up time, come into operation provide safeguard in time for road.
In Fig. 1, column 100 has tubular structure and is erect installed in road side, center or turned with constant interval
Crook；Here constant interval be according to country road guard standard determine, for example, the column clipping room of highway barrier away from
From for 2.5m-3m；Elastic rotary part 200 includes elastic rotary body 210 and rotating shaft 220, and the shape of elastic rotary body 210 is in circle
Cylinder, elastic rotary body 210 have the through hole of portion to bottom insertion elastic rotary body 210 from it, and elastic rotation is inserted in rotating shaft 220
Turn in 210 through hole and form integral structure, i.e. rotating shaft 220 and elastic rotary body 210 rotation or static simultaneously.
Due to a diameter of 140mm of national road guard standard mandatory provisions column, existing elastic rotary body surrounds
The rotationally mounting means of column 100, so, if the through hole of elastic rotary body 210 and column coordinate, it is necessary to be slightly larger than or
Equal to 140mm, the entire outer diameter of elastic rotary body inevitably enlarges, and the volume increase of corresponding elastic rotary body, increases elasticity
The manufacture difficulty of rotary body, while increase cost of manufacture.In addition, the both ends of rotating shaft 220 can with bearing set, horizontal bar 300
End opens up mounting hole, so rotates more freely.
The elastic rotary body 210 of the present invention forms integral structure with rotating shaft 220, and rotating shaft 220 is rotated relative to horizontal bar 300 and tied
Close, the diameter of rotating shaft 220 is smaller, and the diameter of corresponding elastic rotary body 210 is smaller, compared to existing safety barrier, elasticity rotation
The reduction of 210 materials is turned, reduces production cost, and in the case where being impacted by car load, energy good absorption impact energy,
To vehicle play a part of buffering, stably, guiding, reduce collision reaction risk, avoid in vehicle collisions and break away, turn over
Car, effectively increase the security of occupant.
The safety barrier of the present invention is mounted in the road side of outdoor, exposes to the weather, in order to prevent from entering in column 100
Water, antiseptic property is improved, column 100 is provided with end cap 120, and the lower end of end cap 120 is provided with screw thread, set in corresponding column 100
Screw thread, after fastener is fixed, end cap 120 is screwed on, the fixation of end cap 120 and without welding, facilitate installation.
The elastic rotary body 210 of the present invention is made of one kind in ethane-acetic acid ethyenyl ester and flexible polyurethane, and E is compact
A or flexible polyurethane it is elastic splendid, and do not allow it is easily rupturable, it is good in outdoor ageing resistace, stand and expose to the weather, use the longevity
Life length.
The material of elastic rotary body 210 is the mixture of vinylacetate, PUR (EVA) and polyurethane, is had very strong
Elasticity, it is not easy to rupture.Because the elastic rotary body 210 has good bullet and power restoring force, when automobile impacting to the bullet
During property rotary body 210, the shock impulsive contact force of automobile will be effectively absorbed and reduced by elastic rotary body, at the same time it can also avoid
Elastic rotary body is collided and crashed.The guardrail on the one hand can effectively prevent automobile cross medium line swarm into it is head-on opposite
Track collides or flown out track, keeps automobile in correct lanes；On the other hand, automobile impacting guardrail can be reduced
Impulsive contact force, meanwhile, in the presence of automobile crash power, elastic rotary body 210 is pivoted about with column 100, guiding
The gradual adjustment direction of automobile, is located at correct track, avoids occurring to touch again with the automobile on adjacent lane or roadside
Hit, mitigate the extent of injury of accident significantly, reduce injures and deaths, reduce property loss.
It is specific to be reflected in test using in result, collide the impact of the vehicle transmitted, base to the safety barrier of the present invention
Absorbed naturally by the collision deformation of elastic rotary body 210 in sheet, even and relatively strong impact, by with above-mentioned elasticity
Stretcher strain horizontal bar 300 continues to be absorbed counteracting rotary body 210 together, is touched so as to can more effectively absorb counteracting vehicle in structure
Caused impact when hitting, not only protects vehicle, also can effectively prevent outside vehicle derailing to road.
The elastic rotary body 210 of the present invention is integral type or is split type, in the along the circumferential direction table of elastic rotary body 210
Face is provided with annular groove 211, and luminous zone 212 is bonded in groove；Or have and elastic rotary body in the surface recombination of elastic rotary body 210
The luminescent coating of 210 integrative-structures, be advantageous to remind motor vehicle operators to pay attention to road conditions, ensure safe driving.For convenience at night
Between light, fluorescent material can also be added in EVA (ethane-acetic acid ethyenyl ester) and flexible polyurethane material, be then made
Elastic rotary body 210.
Above-mentioned luminescent coating is that light projection can be made when the material to the fluoresent coating of material luminescence, can also be protected even if withdrawing from light
Hold the phosphorescent coating of luminance or when phosphor light, then make the electronics of material of the above-mentioned phosphor of composition from excited state
Through metastable state, recover to one kind in the noctilucence figure layer to be lighted during ground state, can be in the sulfide or zinc sulphide of alkaline-earth metal
Heavy metal, or the micro radium in horizon in the zinc sulphide containing copper are added, is used as luminous paint.
In highway both sides, column 100 directly can be embedded in roadbed；Or column 100 extends downward into horizontal bar 300
Lower section and formation installation landing portion, install landing portion and are connected with base 110, be all provided with positioning hole on base 110 so that safety protective
Column may be mounted on mattess.
Embodiment 2
