The invention provides a jacking mechanism for a four-way vehicle. The jacking mechanism comprises a driving box body, a rigid chain and a jacking plate, a chain rail is arranged in the driving box body, one end of the chain rail extends to the outer side of the box body in the radial direction to form an opening, and a driving chain wheel is installed in the chain rail and driven by a four-way vehicle power assembly. The rigid chain is installed in the chain track and arranged on the outer side of the driving chain wheel in a sleeving mode, one end of the rigid chain extends to the opening side of the driving box body, the jacking plate is installed on a frame of the four-way vehicle in a sliding mode in the radial direction, and one end of the jacking plate is connected with the rigid chain located on the opening side; each rigid chain comprises a plurality of chain plates and chain links, a pin shaft is rotationally installed on each chain plate, the rigid chains are sequentially connected into a whole through the chain links installed between the adjacent pin shafts of every two adjacent chain plates, and a rigid chain structure only bent towards one side is formed between every two adjacent chain plates through a limiting assembly. The bending radius of the rigid chain of the jacking mechanism is small, so that the whole structure is simple, and the installation space is small.

    本发明提供一种用于四向车的顶升机构,包括驱动箱体、刚性链条和顶升板;驱动箱体的内部设有链条轨道,链条轨道的一端沿径向延伸至箱体外侧,形成一开口,在链条轨道内安装有驱动链轮,驱动链轮由四向车动力组件驱动;刚性链条安装于链条轨道内并套设于驱动链轮外侧,且其一端延伸至驱动箱体的开口侧,顶升板沿径向滑动安装于四向车的车架,其一端与位于开口侧的刚性链条相连接;刚性链条包括若干个链板和链节,每个链板上转动安装有销轴,刚性链条通过相邻的两个链板的相邻销轴之间安装链节依次连接为一体,相邻两个链板之间通过限位组件构成仅向单侧折弯的刚性链结构。本申请的顶升机构的刚性链条弯曲半径小,使得整体结构简单,安装空间小。
