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.
本发明公开了一种基于四柱举升机的托升装置。包括托板、公扣、母扣和方盖;托板为梯形条台,托板中间为停车凹槽;坡面表面设有防滑槽;母扣一表面设有半圆型卡槽,公扣与母扣相对配合,母扣通过第一贯通孔固定在托板表面;方盖一表面设有若干第二贯通孔;方盖表面设有半圆形凹槽;凹槽与卡盘和卡槽相对配合。本发明通过设置停车凹槽,将汽车轮胎固定,具有结构简单,操作方便,制作加工工艺方便,使用寿命长等优势;通过设置卡扣固定托板,通过钢丝绳实现汽车吊升,降低结构间的装配方式,减少结构材料,降低生产成本,提高安装维护的效率。
