Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 2, for the utility model discloses a wave form roof beam guardrail, including buffer 210, buffer 210 sets up on the horizontal end between wave form steel guardrail board 200 for cushion when colliding with wave form steel guardrail board 200 to the vehicle.

As shown in fig. 3, the buffering device 210 includes a buffering block 211, the buffering block 211 is connected with the corrugated steel guardrail plate 200 (see fig. 2) in a sliding manner, the sliding direction is perpendicular to the length direction of the corrugated steel guardrail plate, and the initial position of the buffering block 211 is greater than the distance from the highest point of the curved surface of the corrugated steel guardrail plate 200 to the anti-block 300. When the vehicle strikes the corrugated beam guardrail 400, the buffer block 211 firstly contacts the vehicle, and slides close to the upright post 100 under the impact force of the vehicle, when the buffer block 211 slides to be flush with the highest point of the curved surface of the corrugated steel guardrail plate 200, the vehicle can contact the corrugated steel guardrail plate 200 to generate impact on the corrugated steel guardrail plate 200, because when the vehicle directly contacts the corrugated steel guardrail plate 200, the buffer block 211 firstly buffers the impact of the vehicle, so that after the vehicle contacts the corrugated steel guardrail plate 200, the impact force is reduced, and the protection effect on the corrugated steel guardrail plate 200 is achieved.

In order to realize the sliding of the buffer block 211, a buffer spring 214 perpendicular to the corrugated steel guardrail plate 200 is arranged at the horizontal end of the corrugated steel guardrail plate 200, and the buffer block 211 is arranged at one end of the buffer spring 214 far away from the anti-blocking block 300. In order to guide the expansion and contraction of the buffer spring 214, a fixing rod 212 perpendicular to the wave steel fence plate 200 is welded to the horizontal end of the wave steel fence plate 200, and a sliding rod 213 is slidably moved in the fixing rod 212. The buffer spring 214 is disposed in the fixing rod 212, and two ends of the buffer spring are respectively abutted against the bottom wall of the fixing rod 212 and the sliding rod 213, and the buffer block 211 is disposed on the sliding rod 213. When the buffer block 211 is impacted by the vehicle, the sliding rod 213 slides to a position close to the anti-blocking block 300, and the sliding rod 213 compresses the buffer spring 214, so that a part of the impact force is converted into the elastic potential energy of the buffer spring 214, and the impact force of the vehicle directly acting on the corrugated steel guardrail plate 200 is reduced.

In order to disperse the impact force received by the buffer block 211 and guide the vehicle, the buffer block 211 is provided in a spherical shape, and the buffer block 211 is rotatably coupled to the slide lever 213.

In order to further protect the corrugated steel guardrail plate 200, so that the corrugated steel guardrail plate 200 and the obstruction block 300 are horizontally connected in a sliding manner, a rubber pad 220 is arranged between the corrugated steel guardrail plate 200 and the obstruction block 300, the rubber pad 220 is fixedly connected with the obstruction block 300, and the shape of the rubber pad 220 is the same as that of the corrugated steel guardrail plate 200. After the vehicle is buffered by the buffer block 211 and contacts the corrugated steel guardrail plate 200, the impact force acting on the vehicle pushes the corrugated steel guardrail plate 200 to move, the rubber pad 220 is compressed, and the rubber pad 220 absorbs the impact force acting on the corrugated steel guardrail plate 200, so that the time for the collision between the corrugated steel guardrail plate 200 and the obstruction block 300 is prolonged.

The specific working process of this embodiment: when a vehicle impacts the wave beam guardrail 400, the buffer block 211 firstly contacts the vehicle, the buffer block 211 pushes the sliding rod 213 to slide after receiving impact force, and the sliding rod 213 compresses the buffer spring 214. When the buffer block 211 slides to be level with the highest point of the curved surface of the corrugated steel guardrail plate 200, the vehicle contacts the corrugated steel guardrail plate 200, the impact force pushes the corrugated steel guardrail plate 200 to move, the corrugated steel guardrail plate 200 extrudes the rubber pad 220, and the rubber pad 220 absorbs part of the impact force. Because when the vehicle directly contacted with wave form steel guardrail plate 200, buffer block 211 had earlier cushioned the impact of vehicle for the vehicle contacted the back with wave form steel guardrail plate 200, and the impact force diminishes, and under the effect of rubber pad 220, further improved buffering effect, the time of extension wave form steel guardrail plate 200 and preventing hindering piece 300 collision has consequently played the guard action to wave form steel guardrail plate 200.
