The invention provides a connecting rod type oil cylinder lifting axle device and a semitrailer. The connecting rod type oil cylinder lifting axle device comprises a hydraulic system, an oil cylinder fixing frame, an oil cylinder and a connecting rod lifting device. The oil cylinder fixing frame comprises a beam frame formed by connecting a cross beam and a longitudinal beam, and two pieces of guide iron are arranged at the two transverse ends of the beam frame respectively; a base of the oil cylinder is fixed on the beam frame; the connecting rod lifting device comprises a connecting rod lifting beam, two U-shaped bolts and two sliding ways, a horizontal hole is formed in the middle of the connecting rod lifting beam, the upper end of a telescopic rod of the oil cylinder is installed in the horizontal hole through a pin shaft, the two U-shaped bolts are symmetrically installed at the two ends of the connecting rod lifting beam, and the lower portions of the U-shaped bolts form an axle traction part. The two sliding ways are installed at the two ends of the connecting rod lifting beam correspondingly and are in sliding fit with the two pieces of guide iron in the vertical direction correspondingly. The hydraulic system serves as a power source of the oil cylinder; by optimizing the structure, the advantages that an original hydraulic system is better in compatibility, axle lifting is more stable and accurate, and the traction displacement phenomenon is not prone to occurring are achieved.
