Description

Guard rail

Technical field

Road prevention field is the utility model is related to, more specifically, it relates to a kind of guard rail.

Background technology

At present, the traffic accident of Vehicular impact guardrail, vehicle speed often occur on highway or traffic route Degree is too fast, and traditional stiff safety fence can not provide certain buffering for vehicle so that occupant's damage is serious, if rigidity shield Column can effectively absorb impact kinetic energy with slowing down, and the traffic accident driver and conductor damage that the vehicle of traveling hits guard rail can greatly subtract Gently.

There is a kind of guard rail with rotary anti-collision bucket for this with problem in the market, this kind of guard rail includes upper horizontal stroke Beam, the pier stud parallel to the sill of entablature and for installing guard rail, wherein rotary anti-collision bucket are rotationally connected with horizontal stroke Between beam and sill, gas cell or elastomeric material are selected in its outer surface of rotary anti-collision bucket；In Vehicular impact to this kind During guard rail, Anti-collision barrel can change vehicle angle of rebound by spin friction mode, and impact energy is converted into friction energy and rotation Turn energy, help vehicle to go back to the right path；So as to greatly reduce after the occurrence of the traffic accident, the degree of impairment of personnel, but above-mentioned protection Its lower and upper cross-member of column is that rigidity can not be recovered after being hit, and influences its service life.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of guard rail, pass through entablature It is scalable be equipped with the rotatable of each component of sill, so as to can have certain deformation buffer capacity after guard rail is hit It power and can recover, add its service life.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of guard rail, including Two columns in roadside are erected in, the sill of hypomere in column is installed on and is installed on the entablature of column top, lower horizontal stroke Coordinate between beam and entablature and be rotatably connected to multiple Anti-collision barrels, the entablature is in series by multiple upper component head and the tail, phase Component is mutually socketed on neighbour, and junction is filled with the elastic layer with restoring force, and the sill is first by multiple lower components Tail is in series, and adjacent lower component is rotatablely connected.

By using above-mentioned technical proposal, when guard rail is hit, vehicle is entered in advance by the elastic layer of Anti-collision barrel The certain buffering of row, and change vehicle angle of rebound in a manner of spin friction, and impact energy is converted into friction energy and rotational energy, Vehicle is helped to go back to the right path；Entablature mutually deploys so that a circular arc is integrally presented in this section of guard rail top in this process Shape, further vehicle is guided to go back to the right path；Simultaneously in this process because each component of sill can be rotated mutually, from And it will not interfere the stretching of entablature because connecting Anti-collision barrel；After shock terminates, each component of entablature is by elasticity The elastic-restoring force of layer, mutually shrink, each component of sill is drawn by each component of entablature, turns to initial shape State；After undertaking Vehicular impact overcoat by each elastic layer, the deformation power for lower and upper cross-member, and elastic layer has There is restoring force, the service life of guard rail is added with this；If lower and upper cross-member is a continuous pillar, then after shock Permanent deformation will be caused, largely effects on the service life of guard rail.

The utility model is further arranged to：Described upper component one end is provided with connecting hole, and the other end is provided with and connected Borehole jack connects the connecting portion of cooperation, and the connecting hole openend is provided with the edge of varus, and the connecting portion end set has protrusion Platform edge, the elastic layer is filled in edge and platform between.
