The cargo carrying platform trolley comprises a carrying platform, a driving wheel mechanism and two sets of lifting wheel mechanisms arranged on the front side and the rear side of the bottom of the carrying platform respectively, and each lifting wheel mechanism comprises a retracting and releasing mechanism, a telescopic mechanism connected with the retracting and releasing mechanism and a lifting trundle connected with the lifting mechanism. The retracting and releasing mechanism comprises a stepping motor arranged on the bottom surface of the carrying platform, a lead screw connected with the output end of the stepping motor, a ball nut arranged on the lead screw and a connecting rod hinged to the ball nut, and the lifting mechanism comprises a connecting piece arranged on the bottom surface of the carrying platform and an electric push rod hinged to the connecting piece; the connecting rod is hinged to the lifting mechanism; load bearing and moving are achieved through the arranged driving wheel mechanism, lifting of the whole carrying platform is achieved through the lifting wheel mechanism, the height of the carrying platform is reduced and collision is prevented by folding the front lifting wheel and the rear lifting wheel in sequence when goods are loaded and unloaded, the total height of the carrying trolley can be reduced, and meanwhile flexibility of the trolley is improved.

    本发明公开了一种货物运载平台小车,包括载物平台、驱动轮机构和设置在载物平台底部前侧和后侧各一组的升降轮机构,升降轮机构包括收放机构、与收放机构连接的伸缩机构以及与升降机构连接的升降脚轮,收放机构包括设置在载物平台底面上的步进电机、与步进电机的输出端连接的丝杆、设置在丝杆上的滚珠螺母以及与滚珠螺母铰接的连接杆,升降机构包括设置在载物平台底面上的连接件以及与连接件铰接的电动推杆,连接杆与升降机构铰接;本发明通过设置的驱动轮机构来实现承重和移动,通过升降轮机构实现整个载物平台的升降,并在装卸货物时通过先后收起前后升降轮降低载物平台的高度并防止碰撞,可减小载物小车的总高,同时小车增加灵活性。
