Description
Technical field
This utility model relates to a kind of traffic guardrail, particularly relates to a kind of have rotary body, safe and reliable flexibility
Cushion bumper road guard.
Background technology
Along with economic fast development, automobile is commonly used as the one vehicles easily.In China, not people having a common goal
The speed limit on road is the most different, and such as, the general speed limit in urban road is 40 kilometer per hours, and the general speed per hour of common road is 40-
80 kilometer per hours, the general speed per hour of highway is 60-120 kilometer per hour, and therefore the vehicle accident in urban district mostly is and knocks into the back
Accident, on common road or highway, owing to automobile speed is too fast, frequent accidents occurs, the most serious
It is that the automobile run at high speed bumps against on the guard rail of roadside or centre, road, and these guard rails are by concrete building brick or by being spaced
The concret block arranged and the horizontal bar connecting adjacent block are constituted, then or are connected structure by the cross bar of steel construction with column
Become, but, these guard rails cannot absorb the collision kinetic energy of automobile, and collision rift is turned over by the opposition of guard rail, automobile
Turn or reversion deviates former track, as easy as rolling off a log with the automobile generation secondary collision run at high speed, cause many Automobiles to ruin people
Die, exacerbate the hazardness of accident.
For above-mentioned vehicle accident, current Chinese utility model patent (CN202116999U) discloses a kind of interval and connects
The traffic guardrail of ground formula band rotary body, including column, the elastic rotary body being sheathed on column, is respectively arranged at elastic rotary body
Above and below upper rail and bottom rail, be set on column and be arranged on the rotation between bottom rail and elastic rotary body
Supporting, column includes the long column that is arranged alternately and short column, and long column extends downward bottom rail installation formed below and falls
Ground portion, the two ends of short column are connected with upper rail and bottom rail respectively；For another example Chinese utility model patent
(CN202849974U) disclose a kind of SA level type rotary anti-collision guardrail with absorbing impact force rotary body, stand including pipe
Post, the horizontal bar being connected with column, sheathed elastic rotary body on column, it is respectively provided with above and below this elastic rotary body
Horizontal bar and bottom rail, upper rail including at least in the higher level's horizontal bar being arranged above and below and subordinate's horizontal bar, elastic rotary body lower end with under
Being provided with the rotation supporting being set on column between horizontal bar, rotation supporting is two panels.
In two kinds of guardrail structures disclosed above, all include rotation supporting, carried out support elasticity by rotating supporting
The rotation of rotary body, wherein rotates supporting and is only circular planes steel plate, and elastic rotary body is the mixed of EVA material and polyurethane
Zoarium, therefore the frictional force between elastic rotary body and circular plate is relatively big, affects rotating freely of elastic rotary body, elastic rotary
Body can not fully absorb impact force kinetic energy, and then has influence on the using effect of this guard rail.
Summary of the invention
In order to overcome the defect of prior art, it is crashproof that the purpose of this utility model is to provide a kind of new type of safe flexible buffer
Road guard, ensures that rotary body can rotate freely, and reaches rotary body intended absorption buffering collision of closed effect.
A kind of crashproof road guard of new type of safe flexible buffer, including pipe column, the elasticity that is sheathed on pipe column
Rotary body, it is respectively arranged at the upper rail above and below elastic rotary body and bottom rail, is set on column and is arranged on down
Rotation supporting between horizontal bar and elastic rotary body, column includes the long column that is arranged alternately and short column, and long column is downward
Extending to bottom rail installation formed below and land portion, the two ends of short column are connected with upper rail and bottom rail respectively, its feature
It is that described rotation supporting includes collet and has the supporting plate of roller, collet and supporting plate and be set in pipe the most from the bottom to top
On column, elastic rotary body is placed on supporting plate, can realize being freely rotatable under the drive of roller.
This utility model improves further, also includes connecting support, and three, C-shaped connection support all offers through hole,
All offer through hole on upper rail, bottom rail corresponding with two longitudinal holes connecting support, wear connection by the first screw rod
After through hole on two longitudinal holes of frame and upper rail or bottom rail fixing；The horizontal stroke offering through hole on pipe column and be connected support
Corresponding to through hole, fixing worn the cross through hole of column through hole and connection support by the second screw rod after.
This utility model improves further, also include cushion pad, described cushion pad be placed in connection support and upper rail or under
Between horizontal bar, after wearing due to the second screw rod, its screw head and nut are respectively positioned in connection support, and cushion pad is resisted against screw head or spiral shell
On cap, on the one hand it is effectively prevented from upper rail or bottom rail and the second screw rod hard contact, on the other hand can play well
Hit rear horizontal bar buffering effect.
This utility model improves further, and described collet, supporting plate are annulus, and the external diameter of annulus is more than pipe column
Diameter less than the base diameter of elastic rotary body, can be direct with elastic rotary body when such structure ensure that Vehicular impact
Contact, without with collet annulus direct collision；On annulus, symmetry offers gap, and the head of gap and the first screw rod matches
Closing, annulus is placed steadily, and the head by the first screw rod is spacing, will not rotate with elastic rotary body, it is ensured that elastic rotation
The normal rotation turned.
This utility model improves further, and described elastic rotary body is integral type or is split type, at described elastic rotary
The along the circumferential direction surface of body is provided with cannelure, bonding reflective tape in groove；Or the surface recombination at elastic rotary body has and bullet
Property rotary body integrative-structure reflector layer, be conducive to remind motor vehicle operators note road conditions, it is ensured that safe driving.
This utility model improves further, and the installation portion of landing of described long column is connected with base, and base is all provided with peace
Dress hole so that anticollision barrier of the present utility model may be mounted on mattess.
Compared with prior art, advantage is: simple in construction of the present utility model, and the rotation supporting in this structure includes the end
Holding in the palm and have the supporting plate of roller, supporting plate can be freely rotatable on collet, and elastic rotary body is placed on supporting plate, thus bullet
Property rotary body realize be freely rotatable.Road traffic guardrail of the present utility model can be arranged at road center, roadside, road, intersection
