Vertically track rolling on and off device for road-rail vehicle

The utility model discloses a vertically track rolling on and off device for a road-rail vehicle to realize fast and safe track shifting between a road and a railway. The vertically track rolling on and off device for the road-rail vehicle comprises a pedestal, a rotary supporting seat and a plurality of elevating driving mechanisms. The pedestal is connected with the rotary supporting seat via a revolving supporting mechanism; the lower end of the pedestal is provided with a positioning table respectively cooperating with each rail; each group of the elevating driving mechanism is formed by an external stand column, an internal stand column and an elevating oil cylinder; the external stand column is sleeved on the internal stand column; two ends of the elevating oil cylinder are respectively connected with the external stand column and the rotary supporting seat via a pin roll; the internal stand column is fixedly connected with the rotary supporting seat; and two ends of a vehicle frame are respectively fixedly connected with side surfaces of the external stand columns of a group of the elevating driving mechanism. A rotating movement of a complete vehicle is controlled by the vertically track rolling on and off device via the revolving supporting mechanism; elevating actions of the complete vehicle are achieved via the elevating oil cylinder, so that fast and safe track shifting between the road and the railway is realized; and the vertically track rolling on and off device for road-rail vehicle has strong reliability, high operating efficiency, so that operating difficulty is reduced.
