The invention relates to a track driving device based on driving of an oil cylinder. The track driving device consists of a track support frame, track shoes, track pins, pin shaft clamp plates, a transverse oil cylinder and longitudinal oil cylinders, wherein the adjacent track shoes are connected by the corresponding track pin to form an annular track chain ring, the interior of each track chain ring is supported by the track support frame, the track support frame is in sliding friction with each track chain ring, the transverse oil cylinder is a double-piston rod hydraulic cylinder, piston rods at the two ends of the transverse oil cylinder can sleeve vertical columns of the track support frame, the longitudinal oil cylinders are single-piston rod hydraulic cylinders and are positioned at the two sides of the transverse oil cylinder, a cylinder body of each longitudinal oil cylinder is fixedly arranged on the track support frame, a piston rod of each longitudinal oil cylinder is fixedly connected with the corresponding piston rod of the transverse oil cylinder through a bolt without relative displacement, the transverse oil cylinder can be moved along the vertical direction under the telescopic action of the longitudinal oil cylinders at the two sides, one end of each pin shaft clamp plate is fixedly arranged at the outer side of a cylinder body of the transverse oil cylinder, and can be moved along with the cylinder body of the transverse oil cylinder along the horizontal direction, and the other end of each pin shaft clamp plate is engaged with the corresponding track pin. The track driving device has the advantages that the structure is simple, the safety and reliability are realized, and the maintenance is convenient.
