Abstract
The present invention provides a kind of technical solutions of the safety collision-protection device of freeway guardrail, are related to expressway traffic safety facilities technical field.Including the bottom plate being mounted on corrugated guardrail plate, the front of the bottom plate is equipped with multiple deformable bodys, is provided with buffering energy-absorbing chamber in the deformable body.After on Vehicular impact to deformable body, since deformable body itself has good elasticity, the injury collided to vehicle and driver and conductor can effectively reduce；In addition; since the buffering energy-absorbing chamber on deformable body can make deformable body deform; when sharp impacts occur; energy is consumed using the deformation of deformable body; the energy for being transmitted to driver's compartment in this way is less than the ability to bear for driving plot structure without deforming; preferably to guarantee the safety of passenger, injury is reduced, a kind of safety guard without changing existing guard bar structure being mounted in current highway guardrail board.
Description
Technical field
The present invention relates to expressway traffic safety facilities technical field, especially a kind of safety of freeway guardrail is anti-
Collision device.
Background technique
Currently, the protective device shield of all highway and intercity highway is substantially all as waveform steel guard rail.It is pacified
Run-off-road is occurred for vehicle after dress and intercepts protective effect well to being possible to go out highway and play, but to vehicle and personnel
The protection of property safety is relatively limited, and the stress and reaction force that high-intensitive protective fence steel plate is generated in Vehicular impact are to vehicle
And the injury of personnel or huge.Meanwhile making vehicle again due to the rigidity characteristics of waveform Steel material after vehicle collision guardrail
Deceleration is smaller, and vehicle backlash of turning back then is easy to greatly cause secondary traffic accident and repeatedly a chain of traffic accident to the probability of runway very much.
So freeway guardrail how is greatly improved to the protection class of vehicle crew, vehicle collision is reduced to a greater extent
The hardness injury of guardrail is hit in deformation after being spilled over to personnel or even personnel, and makes vehicle reduction of speed that vehicle are trapped in guardrail as far as possible
It is this technical problem to be addressed by invention on neighbouring urgent lane.
Before, have part for problems improvement and solution, but the operability of practice and little, have
It limitation and is not easy to promote on a large scale.Separately having drum-type anticollision barrier is that can effectively improve stiff safety fence to collide with vehicle
Bring hard breakdown, but its middle-size and small-size vehicle more numerous to quantity be it is more fatal, the rotation of rotating cylinder can not be more
The good strength generated to reduce the inertia of speed causes vehicle to change driving direction deviation guardrail and rushes at runway, easily
Cause the generation of secondary traffic accident.
Separately the structure of guardrail is changed, newly-built highway is can be only installed at, the high speed built up can then be made
At the waste of social resources.
This is existing deficiencies in the technology.
Summary of the invention
The technical problems to be solved by the invention aiming at deficiency of the prior art, and provide one kind substantially
Degree improves protection safety grade and installs safety collision-protection device that is simple, upgrading convenient and lower-cost freeway guardrail
Technical solution.
This programme is achieved by the following technical measures: a kind of safety collision-protection device of freeway guardrail, including
The multiple deformable bodys being mounted on corrugated guardrail plate are provided with buffering energy-absorbing chamber, the appearance of the deformable body in the deformable body

Band is provided in the fixed card slot, band loop is fixed on corrugated guardrail plate after fixed card slot.
In addition, the deformable body is rectangle deformable body, the rectangle deformable body includes further improvement of the present invention
Mounting plate and outer energy-absorbing plate, between the mounting plate and outer energy-absorbing plate be equipped with one group of connecting plate, the mounting plate, outer energy-absorbing plate and
Connecting plate constitutes buffering energy-absorbing chamber.
Beneficial effects of the present invention can be more on corrugated guardrail plate including being mounted on according to the description of the above program
A deformable body is provided with buffering energy-absorbing chamber in the deformable body, and the outer surface of the deformable body is provided with multiple drawing friction portions.
When sharp impacts occur, energy can be consumed using the deformation of deformable body, the energy for being transmitted to driver's compartment in this way, which is less than, to be driven
The ability to bear of plot structure, preferably to guarantee the safety of passenger, reduces injury without deforming.Material of the invention has
It is certain flexibility, elasticity, restorative and rigid, while there is energy-absorbing function, antiultraviolet of preventing fires, outside, which is equipped with, increases vehicle and this
Device generates the construction of powerful frictional force and tractive force, i.e. friction portion when contacting, integrally make vehicle may be more when colliding
Good energy-absorbing buffering reduction of speed reduces and reduces to a greater extent collision and brings the personal injury that vehicle deformation brings driver and conductor, mentions
The chances of survival of the personnel of liter.Injury when life entity hits stiff safety fence can be reduced simultaneously, such as the life entity being spilled in traffic accident,
When hitting this device, such as touching air bag protects personnel well.In addition, such device can be widely used in newly
On old guardrail, with installing, simple, construction is convenient, practical, the life of all vehicles and personnel and property can be made to obtain pole
Big protection.
It can be seen that compared with prior art, the present invention implementing with substantive distinguishing features outstanding and significant progress
Beneficial effect be also obvious.
