The invention discloses a carriage lifting device of a sugarcane transfer trolley. The carriage lifting device is characterized in that a square-tube-shaped guide rail is fixed to a base transverse beam and a connecting point of a vertical supporting rod and a diagonal draw bar, an included angle which ranges from 75 degrees to 80 degrees is formed between the guide rail and the base transverse beam, a limiting groove is formed in the guide rail, a guide rod capable of vertically moving in the guide rail is sleeved with the guide rail, the upper end of the guide rod is connected with a carriage through a carriage rotation shaft at the jointing position of the lateral edge and the upper edge of the carriage, a limiting block which vertically moves in the limiting groove along with the guide rod is arranged on the guide rod, a guide rail roller is arranged at the upper end of the interior of the guide rail, a guide rod roller is arranged at the lower end of the guide rod, and a carriage support capable of enabling the carriage to vertically move is welded and fixed to the outer side of the guide rail. A hydraulic cylinder is further fixed to the base transverse beam and the diagonal draw bar, and the upper end of a piston rod of the hydraulic cylinder is connected with the carriage through a hydraulic cylinder rotating shaft. The carriage lifting device has the advantages of being simple in structure, safe, reliable, high in working efficiency, excellent in passing performance and stability and the like.
