Description

Technical Field

[0001] The utility model belongs to the technical field of roads and bridges, and in particular relates to a novel anti-collision guardrail for road and bridges. Background Art

[0002] Road bridge safety guardrails are generally barrier facilities set up parallel to the road. Their main function is to prevent traffic accidents caused by abnormal vehicles running off the road or crossing the central divider into the opposite lane due to driver error or other reasons, and to protect the safety of pedestrians, buildings, car drivers and passengers on the roadside. At the same time, they also have the function of guiding the driver's line of sight, increasing driving safety and beautifying the highway environment.

[0003] At present, most of the safety guardrails of roads and bridges are made of steel or cement, with simple structural design, which is just a column shape connected with a crossbar. When a car hits the guardrail, it will be subjected to a very strong reaction force due to rigid impact without buffering force, which can easily pose a huge threat to the people on the car, and the guardrail will also be damaged. Therefore, we propose a new type of road and bridge anti-collision guardrail. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of road bridge anti-collision guardrail, comprising a fixed pile, a guardrail is arranged on one side of the fixed pile, a U-shaped block is arranged on the side of the fixed pile, a connecting plate is clamped on the side of the U-shaped block, and two fixed blocks are fixedly connected to the side of the connecting plate, and the two fixed blocks are fixedly connected by a sliding rod;

[0006] The surface of the sliding rod is slidably connected to two sliding sleeves, the surface of the sliding sleeve is provided with a sliding block, the sliding block is fixedly connected to the side of the baffle through a connecting assembly, the side of the sliding block is fixedly connected to the side of the fixed block through a first spring, and the surface of the fixed block is fixedly connected to the surface of the baffle through a shock absorbing assembly.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The new road bridge anti-collision guardrail, through the arrangement of the U-shaped block, the connecting plate, the sliding sleeve, the connecting assembly, the first spring and the second spring, can buffer the impact force exerted on the baffle plate through the rebound force of the first spring and the second spring when the vehicle contacts the baffle plate, thereby reducing the damage to the car caused by the rigid impact and further ensuring the safety of the driver and passengers.

[0012] 2.

The left and right sides of the fixed pile 1 are both provided with U-shaped blocks 3, and the connecting plate 4 is fixed by the U-shaped block 3, and the baffle 10 can be further arranged;

[0021] The surface of the slide rod 6 is slidably connected to two slide sleeves 7, and a slide block 8 is provided on the surface of the slide sleeve 7. The slide block 8 is fixedly connected to the side of the baffle 10 through a connecting component 9, and the side of the slide block 8 is fixedly connected to the side of the fixed block 5 through a first spring 11. The surface of the fixed block 5 is fixedly connected to the surface of the baffle 10 through a shock absorbing component 12. In the process of the slide block 8 driving the slide sleeve 7 to move, the first spring 11 can be pressed to contract, and further buffering is performed through the rebound force.
