The invention provides a transfer trolley capable of ascending and descending based on gravity. The transfer trolley comprises a chassis; a lifting assembly comprises a storage rack and two shear forkmechanisms used for lifting the storage rack, the two shear fork mechanisms are arranged on the chassis side by side and support the two sides of the storage rack, and a connecting rod is connected between the two shear fork mechanisms; a springback assembly is arranged between the two shear fork mechanisms and comprises a fixed part and a telescopic part, the fixed part is hinged to the chassis,and the telescopic part is hinged to the connecting rod; when the storage rack is pressed to descend, the shear fork mechanism acts and compresses the springback assembly through the connecting rod.On the basis of the technical scheme, the gravity of goods serves as lifting power, high-intensity labor of manual carrying is omitted, the working efficiency is high. Meanwhile, limitation of the motion range is avoided, the device adapts to various working environments, and the manufacturing and using cost is reduced.

    本发明提供了一种基于重力进行升降的转运小车,包括:底盘;升降组件,其包括置物架与两个用于升降所述置物架的剪叉机构,所述两个剪叉机构并列设置于所述底盘上并支撑所述置物架的两侧,所述两个剪叉机构之间连接有连接杆;回弹组件,所述回弹组件设置在所述两个剪叉机构之间,其包括固定部与伸缩部,所述固定部铰接在所述底盘上,所述伸缩部与所述连接杆铰接;其中,所述置物架受压下降时,所述剪叉机构动作并通过所述连接杆压缩所述回弹组件。基于本发明的技术方案,以货物的重力作为升降的动力,免去了人工搬运的高强度劳动,工作效率高,同时没有运动范围的限制,适应各种工作环境且降低了制造、使用成本。
