The invention discloses a platform lifting mechanism which is simple in structure and low in cost and can satisfy lifting working requirements of a small platform. The platform lifting mechanism comprises pulleys, lifting wire ropes, chain blocks, fixators, fixing seats and supporting lugs. The pulleys are fixed at the top ends of spud legs on the platform. One end of each chain block is connected with one supporting lug on each fixing seat, the other end is connected with one end of each lifting wire rope, and each lifting wire rope is connected with the other supporting lug on each fixing seat after being wound around each pulley. The supporting lugs are symmetrically fixed on the two sides of each fixing seat, and the centers of the connecting holes in the supporting lugs on the two sides directly face the centers of the two sides of each lifting wire rope which is wound around each pulley and downward vertically. The fixing seats are fixed on the platform. One end of each fixator is fixed on each fixing seat, the fixators and the fixing seats are hollow parts, the spud legs are sleeved with the fixators and the fixing seats, and the fixators and the fixing seats can slide with the platform along the spud legs.
