Description
Technical field
This utility model relates to a kind of traffic guardrail, particularly relates to a kind of crashproof road guard having and forwarding structure.
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 invention patent (CN102027173A) discloses a kind of shock-absorbing installation for roadway, is arranged in road
Roadside, Yang Xianhuo road, absorbs when colliding with vehicle and disperses to impact produced by it, including: pillar, in the central authorities of road
Roadside, Xian Huo road, buries underground at regular intervals and fixes and in cylinder body shape；Rotate stay tube, built-in by pillar and can revolve
Turn；Multiple buffer roll parts, form combined mouth to be rotationally arranged at rotation and prop up the outer peripheral face of stay tube, and inside/outside portion is in one
The drum of type elastic rubber material, and high brightness reflective tape is set outside it；Safety rails, presses on buffer roll parts
One determining deviation is set multiple, in the up/down portion of each pillar, each integral is horizontally disposed with；First rotates catching sheet, and its central authorities set
It is equipped with combined hole, and is arranged at the outer peripheral face up/down end rotating a stay tube being provided with buffer roll parts, in combined hole
A side face part forms second and fixes groove and form multiple radial first protuberance projected upwards in its one side, to rotate
Groove is fixed in the one side formation first propping up stay tube, thus is fixed by the first steady pin；Second rotates catching sheet, and its central authorities set
It is equipped with above-mentioned combined hole, and is separately positioned on the up/down end of pillar, so that the second rotation catching sheet is arranged at respectively
Being arranged on the bottom of the first rotation catching sheet rotating a stay tube up/down end, the inner peripheral surface part at combined hole forms the
Four fix groove, to fix groove in the one side of pillar formation the 3rd, thus are fixed by the second steady pin, and in its one side shape
Become multiple radial first protuberance projected upwards, to rotate the kissing forming the first protuberance in catching sheet with first
Close；
In addition Chinese utility model patent (CN202849974U) discloses a kind of SA with absorbing impact force rotary body
Level type rotary anti-collision guardrail, including pipe support, the horizontal bar being connected with column, sheathed elastic rotary body, this elasticity on column
Be respectively provided with upper rail and bottom rail above and below rotary body, upper rail including at least in the higher level's horizontal bar being arranged above and below and
Subordinate's horizontal bar, is provided with the rotation supporting being set on column between elastic rotary body lower end and bottom rail, rotate supporting and be
Two panels.
In three kinds of above-mentioned guardrail structures, all include rotation supporting, carried out support elastic rotary by rotating supporting
The rotation of body, wherein rotates supporting and is only circular planes steel plate, and the mixing that elastic rotary body is EVA material and polyurethane
Body, therefore the frictional force between elastic rotary body and circular plate is relatively big, affects rotating freely of elastic rotary body, elastic rotary body
Impact force kinetic energy can not be fully absorbed, and then have influence on the using effect of this guard rail.
