Problems solved by technology

However, the traditional highway guardrail cannot automatically return to its original shape after being bent and deformed after being hit, especially after being violently hit by a vehicle, the front and rear guardrails will also be linked to produce bending deformation
The deformed guardrail not only makes the maintenance of the guardrail troublesome, but also affects the overall appearance of the highway guardrail.

specific Embodiment approach

[0080] Specific embodiments: In the present invention, the bases 4 of the first guardrail mechanism 1 and the second guardrail mechanism 2 are fixedly installed on the roadbed of the road. A whole guardrail is formed by the first guardrail mechanism 1, the second guardrail mechanism 2 and the protective plate 3. The two sides of the road can be combined together to form a complete guardrail body by adjoining and sequentially side by side. To prevent accidental impact of the vehicle.

[0081] For a guardrail as a whole, when the protective plate 3 between the first guardrail mechanism 1 and the second guardrail mechanism 2 is not hit by the vehicle, one end of the protective plate 3 is in a vertical state with the guardrail square post 5, and how much is wound on the winding pulley 21 Circle buffer belt 20; When hindering piece spring 31 uncompressed, hindering piece 30 has one end of pointed angle 32 to stretch out square guide cylinder 24; The inner ring surface of the ring ...

Abstract

The invention belongs to the technical field of guardrails and particularly relates to a highway guardrail used for municipal engineering. The highway guardrail includes a first guardrail mechanism, asecond guardrail mechanism and a protective board; when the protective board is hit by a car, the impact force can make the protective board move, the protective board pulls buffering belts, and winding belt pulleys release the buffering belts and make first rotating shafts rotate; the winding belt pulleys can release the buffering belts slowly through speed adjusting mechanisms. The higher the impact force performed on the protective board by the car is, the farther the protective board is moved after impact, and meanwhile, the more the buffering belts released by the winding belt pulleys are, the more the consumed impact energy is, so that the function of buffering the impact of the car is achieved, and the effect of protecting the car and a driver is achieved. Additionally, by utilizing compression of first block guiding springs to absorb remaining impact energy, not only can a structural protection effect be achieved, but also a greater impact force of the car can be better buffered, and the driver is better protected.

Description

technical field [0001] The invention belongs to the technical field of guardrails, in particular to a road guardrail used in municipal engineering. Background technique [0002] The road guardrail used in municipal engineering is an important protective measure to prevent vehicles from rushing out of the road after hitting the guardrail. The traditional highway guardrail will bend after being hit by a vehicle, and the curved guardrail can absorb the energy after the impact, so that the vehicle is not easy to be severely crashed, and at the same time, it can play a good role in protecting the vehicle and the driver. However, the traditional highway guardrail cannot automatically return to its original shape after being bent and deformed after being hit, especially after being violently hit by a vehicle, the front and rear guardrails will also be linked to produce bending deformation. The deformed guardrail not only makes the maintenance of the guardrail troublesome, but also...
