The invention discloses a lifting device based on a four-column lifting machine. The lifting device comprises a support plate, male fasteners, female fasteners and square covers, wherein the support plate is a trapezoidal strip platform, a parking groove is formed in the middle of the support plate, skid-resistance grooves are formed in the surfaces of slopes, semicircular slots are formed in onesurfaces of the female fasteners, each male fastener and the corresponding female fastener are matched with each other, each female fastener is fixed to the surface of the support plate through a first through hole, several second through holes are formed in one surface of the square cover, and semicircular grooves are formed in the surface of the square covers; the semicircular groove, chucks andthe slots cooperate with one another. According to the lifting device, through the formation of the parking groove, an automobile tire is fixed, and the lifting device has the advantages of being simple in structure, convenient to operate, convenient in manufacturing and processing technology, long in service life and the like; and meanwhile, the support plate is fixed through the arrangement ofthe fasteners, an automobile is lifted through steel wire ropes, the assembly mode among structures is lowered, the structural materials are reduced, the production cost is lowered, and the efficiencyof installation and maintenance is improved.
