Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, in particular to a road and bridge guardrail with an adjusting effect. Background Art

[0002] Road and bridge guardrails refer to guardrails installed on roads and bridges. They use the deformation of the soil foundation, columns, and beams to absorb collision energy, and force out-of-control vehicles to change direction and return to their normal driving direction to prevent vehicles from running off the road. They have a strong ability to absorb collision energy, thereby protecting passengers and vehicles, reducing losses caused by accidents, and reducing economic losses.

[0003] The existing guardrail height is generally inconvenient to adjust. The guardrail height is difficult to change after it leaves the factory. Different types of bridges require guardrails of different heights to meet specific safety needs, such as cross-river bridges, viaducts, and pedestrian bridges in cities. In addition, in special sections such as slopes and curves of bridges, the fixed height of the guardrail is difficult to meet the protection needs, resulting in the guardrail protection being unable to provide the best protection for specific situations.

During this period, the upper guard plate 106 will drive the arc plate 107 and the telescopic rod 112 to move upward at the same time, and the upper arc plate 107 will slide on the surface of the first movable plate 108, and the telescopic rod 112 and the telescopic casing 111 will also extend, so that the upper roller 113 can slide on the surface of the second movable plate 114, so that the overall height of the guardrail can be adjusted, and the protection height can also be changed together, so that the guardrail can be more suitable for different sections of the bridge and different bridges. After adjusting to the required position, the first screw 104 is twisted into the surface of the main casing 101 and the inside of the adjustment hole 103, so that The side guard plate 102 can be limited. When a vehicle collides with the guardrail from the side, the surface of the vehicle can contact the roller 113, and the roller 113 can drive the telescopic rod 112 to rotate on the surface of the anti-collision plate 110, so that the vehicle can be deviated by the rotation of the roller 113, thereby gradually making the driving route normal.
