Problems solved by technology

[0005] 1. The guardrail has no elastic deformation and cannot provide resilience for the vehicle
[0006] 2. Due to its own structure, the strength of the guardrail is poor, and it is easily damaged during a collision
[0007] 3. When a collision occurs, the vehicle will often stop suddenly, and the energy cannot be released. The huge inertia will cause the vehicle to roll over and cause serious traf

Embodiment 1

[0026] Such as figure 1 As shown, 1 is a main shaft, 2 is a foundation, 3 is a flexible roller, and 4 is an upper connection belt.

[0027] During construction, the multiple main shafts 1 are pre-embedded in the foundation 2, the inner hole of the flexible roller 3 is sleeved on the main shaft 1, and the upper connecting belt 4 fixes the upper ends of the multiple main shafts 1 to increase the overall strength.

[0028] The height of flexible drum 3 can be designed according to the wheel height of truck and bus.

[0029] The way of fixing the upper connection belt 4 and the main shaft 1 can be integral molding, bolt connection, bolt connection, welding, riveting and the like.

[0030] A gap is designed between the plurality of flexible rollers 3 so that their independent rotation is not interfered with.

Embodiment 2

[0032] Such as figure 2 As shown: In order to achieve the purpose of actively detecting accidents, an angular displacement sensor 5 is arranged between the flexible roller 3 and the main shaft 1. The outer ring of the angular displacement sensor 5 contacts the flexible roller 3, and the inner ring contacts the flexible roller 3. Once the flexible roller If there is an angular deviation between 3 and the main shaft 1, the signal line 6 will transmit the signal to the traffic control department.

[0033] The power supply of angular displacement sensor 5 adopts solar cell.

[0034] The angular displacement sensor 5 can also be replaced by a Hall position sensor.

Embodiment 3

[0036] Such as image 3 As shown: on the one hand, in order to further strengthen the overall strength of the guardrail, and on the other hand, in order to save the material of the flexible roller 3 (the lower part of the flexible roller 3 has no effect), this embodiment designs the lower connecting belt 7, the lower connecting belt 7 and the main shaft The fixing method can also be one-piece molding, bolt connection, bolt connection, welding, riveting and other methods. The setting of the lower connection belt 7, in addition to enhancing the overall strength of the guardrail, can also play a role in supporting the flexible drum 3,

Abstract

The invention relates to an anti-collision and anti-rollover flexible roller intelligent protective fence, which comprises a plurality of parallel main shafts, wherein flexible rollers are arranged outside each main shaft in a sleeving way; a gap is formed between the flexible rollers; and a connecting device is fixedly connected with the plurality main shafts. A rotating position sensor is arranged in each flexible roller. The anti-collision and anti-rollover flexible roller intelligent protective fence has the beneficial effects that when scratch or collision, between a vehicle and the protective fence, caused by a traffic accident occurs, a part of energy is counteracted through the deformation of the flexible rollers; the resilience force after the deformation of the flexible rollers can be exerted on a vehicle body, so that the vehicle damage degree due to collision is reduced; meanwhile, the damage degree of the protective fence per se is also reduced; the automatic rotation generated by the flexible rollers after receiving the lateral force achieves the guide effect on wheels, so that the vehicle body corrects the self direction in the direction along the road; and the vehicle body basically cannot generate the rollover phenomenon due to sudden stop. Rotating signals of the flexible rollers can be transmitted to a remote end, so that a traffic administration department can immediately, fast and accurately know traffic information and take emergency measures.

Description

technical field [0001] The invention relates to a safety protection device for road use. 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. The guardrail has no elastic deformation and cannot provide resilience for the vehicle. [0006] 2. Due to its own structure, the guardrail has poor strength and is easily damaged during a collision. [0007] 3. When a collision occu...
