Elastic rotor traffic anti-collision guardrail

The traffic anti-collision guardrail is formed by connecting guardrail sections, each guardrail section comprises stand columns, cross beams, rotor shafts and rotors, more than two cross beams are arranged between the two vertical stand columns, a plurality of rotor shafts are vertically arranged between the cross beams, the rotors are arranged on the rotor shafts in a sleeving mode through through holes in the centers of the rotors, and the rotor shafts are connected with the cross beams. The guardrail is characterized in that the central height of a cross beam at the lowermost end of the guardrail section is 0.3-0.5 m, and the central height of a cross beam at the uppermost end of the guardrail section is 0.8-1.3 m; the stand column is connected with the cross beam through a cross beam and stand column connecting plate; the connecting mode of the adjacent guardrail sections is that the adjacent cross beams of the adjacent guardrail sections are connected to the shared stand column through the guardrail tran
