Structure, described safeguard structure include clad, upper buffer board, lower buffer board, two horizontally sets solid with column
Fixed sleeve, two slide bars, two springs and about two the spaced hydraulic dampers connected, two sets
Cylinder is arranged at interval in the upper and lower, and upper buffer board, the longitudinal section of lower buffer board are sector structure, upper buffer board and under
One end of the arcwall face of buffer board is provided with multiple detent projection, the detent projection on upper buffer board and lower buffering
Detent projection on plate engages each other, one end away from arcwall face of upper buffer board and lower buffer board respectively with two
The right-hand member of slide bar is hinged, and two slide bars are inserted in two sleeves respectively, and the middle part of described slide bar is provided with annular table
Rank, the right-hand member of described sleeve is provided with for ring-shaped step carries out spacing spacing annulus, two spring positions respectively
In two sleeves, the left end of described spring is resisted against the left end of sleeve, and the right-hand member of spring is sleeved on slide bar also
Being resisted against on ring-shaped step, the left end of two hydraulic dampers is hinged with column respectively, two hydraulic dampers
Right-hand member respectively with the bottom of upper buffer board, the upper articulation of lower buffer board, one end of described clad is fixedly installed
On the sleeve of upside, its other end is fixedly installed on after walking around buffer board and lower buffer board on the sleeve of downside.
In this technical scheme, upper buffer board and lower buffer board are engaged each other by detent projection, so work as cladding
Layer is when being clashed into, act on buffer board and the right side of lower buffer board, upper buffer board and lower buffer board synchronize to
Left part moves, and carries out first order buffering by intermeshing structure, and two hydraulic dampers are respectively acting on
Upper buffer board and lower buffer board, carry out second level buffering to upper buffer board and lower buffer board to the impulsive force of left end,
External impact power is born during left movement, two slide bars hinged with it at upper buffer board and lower buffer board
Third level buffering is carried out by two springs.This guardrail can effectively absorb the impact force of errant vehicle, thus
The excessive damage in rigid knockout process, vehicle produced can be reduced, meanwhile, also can prevent the mistake of safeguard structure
Degree deformation or separated with column.
Further, in order to improve the resistance to impact of clad, described clad is that elastomeric material is made.
Further, in order to alleviate the overall weight of buffer board, described upper buffer board and lower buffer board are hollow knot
Structure.
