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 in particular relates to a highway guardrail used in municipal engineering, which includes a first guardrail mechanism, a second guardrail mechanism and a protective plate, wherein when the protective plate is hit by a vehicle, the impact force will make the protective plate move, The protective plate pulls the buffer belt, winds the pulley to release the buffer belt, and winds the pulley to make the first rotating shaft rotate; the speed regulating mechanism enables the winding of the pulley to release the buffer belt at a relatively slow speed. The greater the impact force of the vehicle hitting the fender, the farther the fender is moved by the impact, the more buffer belts are released by winding the pulley, and the more impact energy is consumed, thus realizing the function of buffering the vehicle impact and being able to play To protect the vehicle and the driver and passengers. In addition, the first guide block spring is compressed to absorb the remaining impact energy, which can not only protect the structure, but also better buffer the greater impact force of the vehicle, and further protect the driver and passengers.

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...
