Rotating barrel type intelligent crash pad for expressway

The invention belongs to the technical field of traffic equipment, and particularly relates to an expressway rotating barrel type intelligent anti-collision pad which comprises a plurality of anti-collision rods distributed at equal intervals in the front-back direction, and the multiple anti-collision rods are fixedly connected together through mounting supports which are symmetrically arranged in the up-down direction. And the lower end of the anti-collision rod is fixedly connected with an anchoring seat anchored in the ground. According to the invention, the collision force strength of the vehicle can be detected and fed back, and the rotation resistance between the rear barrel type anti-collision pad and the anti-collision rod can be adaptively adjusted based on the collision strength of the vehicle, so that the risk of secondary collision increase caused by an overlong sliding distance of the vehicle on the anti-collision pad is avoided; according to the anti-collision rod, the anchoring strength of the
