The technical scheme includes that the rotary anticollision guardrail comprises multiple sets of guardrail units which are sequentially arranged in the horizontal direction, each set of the guardrail unit comprises an upper cross rod and a lower cross rod, multiple uprights are sequentially arranged between the upper cross rod and the lower cross rod in the horizontal direction and are perpendicular to the cross rods, an elastic rotary body is sleeved outside each upright, and the distance between each two adjacent uprights is three times that of the thickness of each elastic rotary body. The rotary anticollision guardrail used for the emergency dangerousness avoiding areas has the advantages that collision force of out-of-control vehicles can be absorbed, the vehicles can be guided to correct road sections, and the rotary anticollision guardrail is convenient to repair.
Description
Technical field
The utility model relates to the traffic anticollision barrier, and is specifically a kind of for the speedway rotary anticollision barrier of long descending highway section urgent danger prevention band continuously.
Background technology
Truck needs the highway section of turning again in the continuous long descending highway section, particularly long descending of speedway, because long-time braking, occur runaway conditions such as brake failure, steering wheel be stuck easily.Behind the truck run-off-road, still can't slow down, the urgent danger prevention band generally is set outside the turning road.The urgent danger prevention band cushions highway section, stone uphill way and outside cement protecting wall by stone to be formed, by vehicle is cushioned and slowing down in two stone highway sections.But, when the excessive velocities of errant vehicle or quality are heavier, the substantial deviation track, can directly clash into the cement protecting wall, and the cement protecting wall can not absorb impulsive contact force, also vehicle correctly can't be guided toward the stone highway section, also can cause automobile upset or counter-rotating to the opposition of vehicle; After having an accident, if cement protecting wall damage is serious, repair also very bothers, it is long to last the time, and the rehabilitation cost height influences the normal operation of urgent danger prevention band.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of rotary anticollision barrier for the urgent danger prevention band is provided, and can absorb the impulsive contact force of errant vehicle, with the extremely correct highway section of guiding vehicles, and is convenient to repair.
For this reason, the technical solution adopted in the utility model is as follows: the rotary anticollision barrier that is used for the urgent danger prevention band, its technical characterictic is, it comprises many group fence units, organizes fence unit more and is arranged in order in the horizontal direction, and every group of fence unit comprises upper and lower two cross bars, be provided with many root posts between two cross bars, column is arranged in order in the horizontal direction and is all vertical with cross bar, the flexible rotary body of column overcoat, and the distance between adjacent two root posts is greater than the twice of elasticity rotary body thickness.
Fence unit is fixed on the cement protecting wall of urgent danger prevention band by upper and lower two cross bars, and the frictional force between elasticity rotary body and the column keeps the stable of both relative positions, and only when being subjected to extraneous impulsive contact force and influence, rotary body just turns.When long descending curves the heavier errant vehicle substantial deviation track of highway section excessive velocities or quality, clash into this elasticity rotary body, because the elasticity rotary body has good elastic force and restoring force, can absorb the impulsive contact force of vehicle effectively, make its deceleration; On the other hand, under the effect of automobile impulsive contact force, the elasticity rotary body rotates centered by column, and steer motor is adjusted direction gradually, makes it enter correct track; After having an accident, if anticollision barrier is damaged, the unit that only need unload damage gets final product, and it is convenient to change, and rehabilitation cost is low, and it is short to last the time.
As improvement, described column by both ends respectively through being fixed in the upper and lower cross bar between two cross bars.This setting makes to be connected more firmly between column and upper and lower two cross bars that syndeton is simple, cross bar easy to process; And, detachable between column and the cross bar, convenient transportation.
As improvement, described elasticity rotary body evagination is in cross bar.This setting makes rotary body absorb the better effects if of vehicle impulsive contact force, and is also better to the guide effect of vehicle, and avoided vehicle directly to clash into cross bar and caused the cross bar gross distortion.
As improvement, the upper and lower both sides of described cross bar all outwards are bent to form first flange, all form a plurality of first through holes on first flange.This setting makes that the syndeton between cross bar and the cement protecting wall is simple, firm.
As improvement, the equidistant even distribution of described column.This setting makes the easy for installation of column.
As improvement, described many group fence units splice from beginning to end.This setting makes many group fence units splice the back from beginning to end and forms a guardrail chain, and the cement protecting wall is put in order segment protect, more can use the requirement of arc cement protecting wall, absorbs the better effects if of vehicle impulsive contact force, and is also better to the guide effect of vehicle.
As improvement, it also comprises a guide, this guide is arranged on the end near the anticollision barrier of first group of fence unit, it comprises a guiding surface, the thickness of guiding surface reduces to the end away from fence unit gradually at the end near fence unit, and the both sides up and down of guiding surface all outwards are bent to form second flange, all form a plurality of second through holes on second flange.This setting by the guiding surface guiding of colliding that liquidates, has increased to meet and has hit area, and vehicle is had cushioning effect preferably.
As improvement, described fence unit also comprises two connecting rods, and two connecting rods all are arranged in the cement protecting wall of urgent danger prevention band and are corresponding with upper and lower two cross bars respectively; Connecting rod comprises that one connects panel and upper and lower two side panels, connects to form the hole corresponding with first through hole on first flange on the panel, and cross bar is locked on the corresponding connecting rod by lock-screw.This setting, make between cross bar and the cement protecting wall be connected more firm.
As improvement, described fence unit also comprises upper and lower two push rods, the end of the rear end of push rod and the side panel of connecting rod offsets, and the front end of push rod passes connecting rod and cement protecting wall and column and offsets, and the lateral wall of push rod front end and the inside wall of cross bar offset.This setting makes push rod to connecting rod, cross bar, column support force be arranged, and has avoided extension bar, cross bar, column to collide distortion easily because of vehicle.
As improvement, the surface of described elasticity rotary body is provided with the bonding groove of reflective membrane, bonding reflective membrane in this groove; Perhaps, the surface recombination of described elasticity rotary body has reflector layer.
The beneficial effects of the utility model are mainly reflected in: first, when long descending curves the heavier errant vehicle substantial deviation track of highway section excessive velocities or quality, bump elasticity rotary body, because the elasticity rotary body has good elastic force and restoring force, can absorb the impulsive contact force of vehicle effectively, make its deceleration; The second, under the effect of vehicle impulsive contact force, the elasticity rotary body rotates centered by column, and steer motor is adjusted direction gradually, makes its stone highway section that enters the urgent danger prevention band, continues to slow down; The 3rd, after having an accident, if anticollision barrier is damaged, the unit that only need unload damage gets final product, and it is convenient to change, and rehabilitation cost is low, and it is short to last the time.
