Description
Technical Field
The utility model relates to a guardrail technical field specifically discloses highway guardrail collision buffer structure.
Background
In recent years, with the increasing of automobile keeping quantity and highway mileage in China, traffic accidents on roads are also increasing year by year, wherein the accidents of about 1/3 are caused by the collision of automobiles and guardrails. The miniaturization, the large-scale and the heavy-duty of the automobile lead the defense performance of the prior guardrail to be continuously reduced, and cause huge casualties and property loss every year. How to improve the protectiveness and the buffering effect of the guardrail can have very realistic and important significance.
The main form of highway guardrail is a continuous structure with corrugated steel guardrail plates spliced with each other and supported by upright posts. The deformation of the soil foundation, the upright posts and the cross beams is utilized to absorb collision energy, and an out-of-control vehicle is forced to change the direction and recover to a normal running direction, so that the vehicle is prevented from rushing out of a road, the vehicle and passengers are protected, and the loss caused by accidents is reduced.
At present, the guard rail of the highway is generally composed of a stand column and a wave-shaped guard plate positioned on the upper portion of the stand column, the guard plate is made of steel plates, the guard plate and the guard plate are rigidly connected through rigid materials, although the guard plate can initially absorb the impact force of a vehicle, the buffer effect and the impact force absorption effect are limited, the multi-stage buffer of the vehicle cannot be realized, and the serious loss of the vehicle and the casualties are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve traditional guard plate and cross just easily roll over, the limited problem of buffering effect.
In order to achieve the purpose, the utility model discloses a basic scheme provides highway guardrail collision buffer structure, including a plurality of support columns and two guardrails of fixing respectively at a plurality of support column upper sections and hypomere, be equipped with a plurality of crashproof gasbags between two guardrails, all rotate in the middle of the crashproof gasbag and be connected with the dead lever, dead lever upper end and lower extreme all with the guardrail rigid coupling, crashproof gasbag is inside all to be equipped with the cylinder, cylinder one side is equipped with the opening towards the inside relief valve of cylinder, the cylinder opposite side is equipped with the opening towards the inside relief valve of crashproof gasbag, sliding seal is connected with the slider in the cylinder, slider sliding connection is on the dead lever, the crashproof gasbag bottom is equipped with and holds the gliding opening.
The principle and effect of this basic scheme lie in:
1. be equipped with a plurality of air bags between two guardrails, the rotation is connected with the dead lever in the middle of the air bag, and the dead lever all with the guardrail rigid coupling, when the car hit to air bag, air bag can produce and rotate and unload a part of impact force, plays better cushioning effect.
2. The inside cylinder that all is equipped with of anticollision gasbag, cylinder one side is equipped with the opening and towards the inside relief valve of cylinder, the cylinder opposite side is equipped with the opening and towards the inside relief valve of anticollision gasbag, when anticollision gasbag receives the striking, gas between anticollision gasbag and the cylinder receives the extrusion, open the opening and towards the inside relief valve of cylinder, gas gets into in the cylinder, promote the slider lapse, make supporting legs and ground contact, the impact force that anticollision gasbag received is big more, gas gets into in the cylinder more fast more, slider slip range is big more, the supporting legs is just inseparabler with the contact on ground more fast, play the effect of fixed whole buffer, make the striker can be faster get back to stable state, can not rush out of the way.
3. Compared with the prior art, the device has adopted the combination of rotatory gasbag and cylinder, makes it can play a heavy cushioning effect when rotatory, plays the heavy cushioning effect of second when the extrusion gasbag, makes gaseous promotion slider when the extrusion gasbag, promotes the supporting legs and supports tightly with ground, plays fixed whole device and stabilizes the effect of rammer, more can play the effect of personnel on the protection vehicle than playing hard guard plate.
Furthermore, a buffer is filled between the anti-collision air bag and the air cylinder. Provides better buffering effect and protects the driver and passengers on the vehicle.
Further, the guardrail is wave. The wave-shaped beam guardrail has the advantages of being compatible in steel and flexibility, strong in capacity of absorbing collision energy, good in sight induction function, capable of being coordinated with the line shape of a road, attractive in appearance, capable of being used on a small-radius curve and easy to replace a damaged part.
Further, the support columns are connected with the guardrails through bolts. Simple structure, reliable connection and convenient assembly and disassembly.
Further, the fixed rod is connected with the guardrail through bolts. Simple structure, reliable connection and convenient assembly and disassembly.
