The invention provides a new type of highway guardrail, which belongs to
Guardrail technology field. The new highway guardrail includes a base and
Turn the buffer mechanism. The rotation buffer mechanism includes a bottom beam,
Top beams, columns, bearings, wheel hubs, elastic rings and soft washers, as described
The bottom beam is fixedly connected to the middle side of the base, and the
The top beam is fixedly connected to the top side of the base, and the column
Spacers are fixedly connected between the bottom beam and the top beam,
Both ends of the upright columns are fixed through the top and bottom of the bottom beam.
At the bottom of the top beam, several bearings are provided, and the
The inside of the bearing is keyed to the column, and the inside of the hub is connected to the
The peripheral side of the bearing is fixedly connected, and the inner side of the elastic ring is connected to the wheel
Fixed connection on the outside of the hub. The present invention can achieve multiple impact car collisions
The vehicle performs buffering and unloading force, which reduces the impact of the driving vehicle on the guardrail and the impact on people.
