Embodiment 1

[0032] Such as figure 1 As shown, a kind of anti-collision guardrail with cushioning function provided by the embodiment of the present invention includes a wave guardrail 10, and also includes:

[0033] A buffer mechanism, which includes a number of rollers 21, a guide block 20 arranged at the upper end of the rollers 21 and one-to-one corresponding to the rollers 21, an upper support plate 22 arranged at the lower end of the rollers 21 and corresponding to the rollers 21 one-to-one, and rotatably arranged on Several guide wheels 11 on the corrugated guardrail 10, the roller 21 can rotate relative to the guide block 20 and the upper support plate 22, the upper support plate 22 is slidably arranged on the installation foundation, the guide block 20 is provided with a guide groove, and the guide groove is C-shaped structure, the guide wheel 11 is connected to the wave guardrail 10 through a rotating shaft, the guide wheel 11 is located in the guide groove, the rotating shaft ex...

Embodiment 2

[0036] On the basis of Example 1, as Figure 2 to Figure 8 As shown, this embodiment also includes a secondary buffer mechanism, such as figure 2As shown, it includes a lower support plate 25, a telescopic mechanism and two buffer springs 26. The upper support plate 22 corresponds to the lower support plate 25. The telescopic mechanism includes a first connecting rod 23 and a second connecting rod 24. The rod 23 and the second connecting rod 24 are arranged crosswise, the first connecting rod 23 is provided with a first chute 231, the second connecting rod 24 is provided with a second chute 241, the first chute 231 and the second chute 241 They are connected by a pin shaft, the pin shaft is slidably arranged in the first chute 231 and the second chute 241, the lower support plate 25 is provided with a support block 251, and the support block 251 is provided with a chute for relief 252, one end of the first connecting rod 23 is hinged on the upper support plate 22, and the ot...

Embodiment 3

[0040] Such as Figure 9 and Figure 10 As shown, the drum 21 is provided with a number of baffles 211. When the drum 21 rotates, the baffles 211 are driven to rotate. to turn.

[0041] Wherein, the cross-section of the baffle plate 211 is a triangular structure that gradually converges in a direction away from the drum 21 .

[0042] When the vehicle hits, it drives the roller 21 to rotate, and when the roller 21 rotates, it will drive the baffle 211 to rotate. When the first roller 21 rotates, it will drive the baffle 211 to rotate. Taking the clockwise direction as an example, the baffle 211 will drive the adjacent other A roller 21 rotates in the opposite direction, that is, counterclockwise. When the baffle 211 hits the adjacent baffle 211, it will produce an impact and consume part of the energy, and when the vehicle deviates and continues to move, it will hit the next adjacent roller. 21 on the baffle plate 211, and at this time, the rotation direction of the baffle p...

Abstract

The invention discloses an anti-collision guardrail with a buffer function, which belongs to the field of guardrails. The device includes a wave guardrail, and also includes: a primary buffer mechanism, which includes a number of rollers, a guide block arranged at the upper end of the rollers and one-to-one corresponding to the rollers, an upper support plate arranged at the lower end of the rollers and corresponding to the rollers one-to-one and rotatably A number of guide wheels arranged on the wave guardrail, the roller can rotate relative to the guide block and the upper support plate, the upper support plate is slidably arranged on the installation foundation, the guide block is provided with guide grooves, the guide wheels are located in the guide groove, and the adjacent The two guide blocks are connected by a return spring. The invention uses a buffer mechanism to enable the vehicle to produce a certain guiding effect under the rotation of the roller during impact, thereby reducing the possibility of rollover, reducing the deformation and damage of the roller due to the impact force, and at the same time energy consumption can also be absorbed The impact force of the vehicle reduces the damage to the vehicle.

Description

technical field [0001] The invention relates to the field of guardrails, in particular to an anti-collision guardrail with a buffer function. Background technique [0002] When the vehicle is running on the road, traffic accidents caused by various reasons will cause the vehicle's driving direction to deviate from the road. In order to prevent the vehicle from rushing out of the roadbed, wave guardrails or steel rope protection are widely used on roads (especially expressways) at this stage. The bar has the effect of blocking and restricting the vehicle. [0003] In practice, the disadvantages of corrugated or wire-rope barriers are: [0004] The guardrail is made of metal and is in rigid contact with the car body. The collision will cause great damage to the vehicle and personnel. [0005] 1. Due to its own structure, the strength of the guardrail is poor, and it is easily damaged during a collision. [0006] 2. When a collision occurs, the vehicle will often stop sudden...
