The invention provides a primary-secondary type four-column lifting machine, and relates to the technical field of four-column lifting machines. The child-mother type four-column lifting machine comprises two transversely-distributed bases, stand columns are fixedly connected to the two ends of each base, two connecting columns are fixedly connected between the two bases, a mother lifting plate capable of ascending and descending is arranged between every two stand columns, and the mother lifting plates ascend and descend through a mother lifting mechanism. A child lifting mechanism is arranged in the middle of the upper surface of the mother lifting plate, and a child lifting plate is arranged at the upper end of the child lifting mechanism. The base, the stand columns, the connecting columns and the limiting columns are arranged and matched with the driving effect of the primary lifting mechanism, the two primary lifting plates can be driven to move synchronously, on one hand, the synchronism is improved, on the other hand, the four stand columns can be limited, the overall stability is improved, under the effect of the secondary lifting mechanism, the secondary lifting plates are lifted, and the lifting efficiency is improved. And secondary lifting of the vehicle is achieved.
本发明提供一种子母式四柱举升机,涉及四柱举升机技术领域。该子母式四柱举升机,包括两个横向分布的底座,两个所述底座的两端均固定连接有立柱,两个所述底座之间固定连接有两个连接柱,两两所述立柱之间设置有可进行升降的母升降板,所述母升降板通过母升降机构进行升降,所述母升降板的上表面中部设置有子升降机构,所述子升降机构的上端设置有子升降板。本发明通过设置有底座、立柱、连接柱和限位柱,并配合母升降机构的驱动作用,即可带动两个母升降板进行同步移动,一方面提高同步性,另一方面可对四个立柱进行限位,提高整体的稳定性,且在子升降机构的作用下,即对子升降板进行举升,实现对车辆进行二次举升。
