Description
Technical field
The present invention relates to a kind of guardrails slowing down frontal impact, specifically use the guardrail of special construction, can be with
It effectively prevent automobile front directly to collide, belongs to field of traffic.
Background technology
Nowadays many traffic accidents make one to lose relatives, many traffic accidents are all related with guardrail, although guardrail
But at the same time in order to avoid a part of traffic accident, there are also the accident caused by guardrail, can have the vehicles of some accidents due to
It is improper to drive, and has directly knocked the top of guardrail, and since guardrail is integrally fixed at ground, vehicle is directly installed in top, huge
Impulsive contact force can directly by vehicle tearing into two, although the starting position now with some guardrails bends a part and avoids outward
Such case, but effect is not satisfactory, and also the guardrail in road center has no idea that this structure, hidden danger is used still to exist.
Invention content
In view of the above-mentioned deficiencies, the present invention provides a kind of vehicle for being directed to and being possible to directly knock guardrail top, slows down punching
Power is hit to avoid a kind of guardrail slowing down frontal impact of accident.
The present invention is achieved by the following technical solutions：A kind of guardrail slowing down frontal impact, including Crashworthy plate, support
Bar, six rib fixed frames, column, spring, front apron, rear baffle, guardrail board, casing, track, track sliding block, track spring and ground
Stake, the cylindric supporting rod for fixedlying connected to the inner side several Intermediate Grays and being fixed with front apron of the Crashworthy plate, the front end of front apron
Supporting rod passes through a six rib fixed frames, the rear end of supporting rod to sequentially pass through rear baffle with holes, six rib fixed frames and casing,
Spring is installed between front apron and rear baffle on supporting rod, the column with muscle is fixed in the inside of six rib fixed frames,
The both sides of six rib fixed frames are fixed with guardrail board, are equipped with track in the lower end of first column, are equipped with and are fixedly connected in track
Track sliding block on column inside track, is equipped with track spring, is stood since second column on rear side of track sliding block
It is fixedly connected with the threaded pile of long taper below column, the casing rear end is fixedly connected on six rib fixed frames.
The Crashworthy plate is the C-shaped of intermediate smooth bending two ends, and thickness is between 0.3~2.5cm.
The quantity of the supporting rod is 1~5, and vertical section is arranged in uniform force shape, is pacified on each supporting rod
Dress there are one spring and a front apron, the quantity of six rib fixed frames and the quantity in the hole on rear baffle and position and supporting rod and
Position is corresponding, and the diameter in hole is bigger 1~2mm than the diameter of supporting rod.
The quantity of the casing is identical as the quantity of supporting rod, on casing the diameter in hole it is bigger than the diameter of supporting rod by 1~
2mm。
The ground of the column is suitable with height above ground level, and track is all located at below ground with pile.
The length of the casing is more than Crashworthy plate to the horizontal length of track rear end.
The usefulness of the invention is when vehicle frontal directly knocks guardrail top, to be in direct contact Crashworthy plate,
Crashworthy plate can head on supporting rod and move backward, and due to the effect of spring and rear baffle, will produce a reversed power and offset one
Point power collided, if the too fast buffering that can so enter second part of speed, Crashworthy plate withstand on first column, drive the
One column moves backward, to further compressed spring and compression track spring, forms second and buffers, by delaying twice
Punching, it will substantially reduce the vehicle for knocking and, car body tearing is avoided to cause the accident.

Specific implementation mode
A kind of guardrail slowing down frontal impact, including it is Crashworthy plate 1, supporting rod 2, six rib fixed frames 3, column 4, spring 5, preceding
Baffle 6, rear baffle 7, guardrail board 8, casing 9, track 10, track sliding block 13, track spring 11 and pile 12, the Crashworthy plate
The 1 cylindric supporting rod 2 for fixedlying connected to the inner side several Intermediate Grays and being fixed with front apron 6, the supporting rod 2 of the front end of front apron 6 pass through
The rear end of one six rib fixed frame 3, supporting rod 2 sequentially passes through rear baffle 7 with holes, six rib fixed frames 3 and casing 9, is supporting
Spring 5 is installed between the front apron 6 on bar 2 and rear baffle 7, the column 4 with muscle is fixed in the inside of six rib fixed frames 3,
It is fixed with guardrail board 8 in the both sides of six rib fixed frames 3, track 12 is equipped in the lower end of first column 4, is equipped in track 12
The track sliding block 13 being fixedly connected on column, inside track 10, the rear side of track sliding block 13 track spring 11 is installed, from
Second column 4 starts 4 lower section of column and is fixedly connected with the threaded pile 12 of long taper, and 9 rear end of casing, which is fixed, to be connected
It is connected on six rib fixed frames 3.
In order to enable Crashworthy plate 1 to bear the shock of strength, the Crashworthy plate 1 is the C-shaped of intermediate smooth bending two ends,
Thickness is between 0.3~2.5cm.
Shock in order to enable devices to sustain strength makes device be unlikely to deform, and the quantity of the supporting rod 2 is 1~
5, vertical section is arranged in uniform force shape, is respectively mounted that there are one spring 5 and a front apron 6, six ribs on each supporting rod 2
Fixed frame 3 is corresponding with the quantity of supporting rod 2 and position with the quantity in the hole on rear baffle 7 and position, and the diameter in hole is than support
Big 1~the 2mm of diameter of bar 2.
In order to make the supporting rod moved backward possess the space moved backward, and can smoothly move forward and backward, it is described
The quantity of casing 9 is identical as the quantity of supporting rod 2, and the diameter in hole is bigger 1~2mm than the diameter of supporting rod 2 on casing 9.
In order to make guardrail more stable and stronger, the ground of the column 4 is suitable with height above ground level, track 10 and pile
12 are all located at below ground.
In order to enable supporting rod to protrude fully into casing, the length of the casing 9 is more than Crashworthy plate 1 and arrives track 10
The horizontal length of rear end.
When automobile front knocks Crashworthy plate 1, Crashworthy plate 1 drives supporting rod 2 to move backward, the front apron 6 on supporting rod 2
Compressed spring 5, when supporting rod 2 moves backward to the position of column 4, Crashworthy plate 1 heads on column 4 and moves backward, spring 5 by into
One step is compressed, while track spring 11 is compressed, and pile 12 squeezes into the guardrail part that underground fixes rear end, and buffering will twice
Slow down the impulsive contact force of automobile significantly.
Above-mentioned specific implementation mode cannot function as limiting the scope of the invention, for the technology people of the art
For member, any alternate modification or transformation made to embodiment of the present invention are all fallen in protection scope of the present invention.
Place is not described in detail by the present invention, is the known technology of those skilled in the art of the present technique.
