The invention discloses an intelligent road height restriction frame. The intelligent road height restriction frame comprises a portal frame, at least one lifting component and at least one electronic control device, wherein at least one lifting component is fixedly arranged on the portal frame; each lifting component comprises a motor, a speed reducer, a converter, a leading screw and nut mechanism, a shearing knife and fork, a lifting rod and a height restriction rod; the motor drives a leading screw of the leading screw and nut mechanism to rotate by virtue of the speed reducer and the converter; the upper end of the shearing knife and fork is connected with a nut of the leading screw and nut mechanism, and the lower end of the shearing knife and fork is connected with the lifting rod through a sleeve; the height restriction rod is connected with the lifting rod; and at least one electronic control device is mutually and electrically connected with at least one lifting component one by one and used for controlling the motor to rotate forward and reversely. The intelligent road height restriction frame disclosed by the invention is simple in structure, the height of the height restriction frame is adjustable, and intelligent adjustment can be realized by virtue of the electronic control device and the motor, so that manpower and material resources which are invested for road control are effectively reduced.
