A center gear and two bottom layer chain fixing seats are arranged at the top of a bottom plate of a bottom layer assembly of the center-passing pallet fork device, a motor is arranged at the bottom of the bottom plate, and transmission chains are fixed to the two bottom layer chain fixing seats. A rack in transmission connection with the center gear is arranged at the bottom of the sliding plate of the middle-layer assembly, and the transmission chain is wound on the corresponding chain wheel on the sliding plate. An upper-layer chain fixing base is arranged at the bottom of the pallet fork plate of the upper-layer assembly, and the other end of the transmission chain penetrates through the sliding plate to be fixed to the corresponding upper-layer chain fixing base. The pallet fork device has the beneficial effects that the pallet fork device can cross the center of the pallet fork to take and place goods and is suitable for the situation that goods need to be positioned in the middle and taken and placed on the two sides. Moreover, by adopting the structure that the bottom-layer assembly, the middle-layer assembly and the upper-layer assembly slide layer by layer, the stroke is longer when goods are forked, only one motor is needed to drive the middle-layer assembly and the upper-layer assembly to act at the same time, the structure is ingenious, and the cost is low.

    本发明公开了一种过中心的货叉装置,其底层组件的底板的顶部设有中心齿轮和两个底层链条固定座,底板的底部设有马达,两个底层链条固定座上均固定有传动链条。中层组件的滑板的底部设有与中心齿轮传动连接的齿条,传动链条绕设在滑板上与其对应的链轮上。上层组件的货叉板的底部设有上层链条固定座,传动链条的另一端穿过滑板而固定在与其对应的上层链条固定座上。本发明的有益效果:该货叉装置可以越过货叉中心取放货物,适用于货物要求居中定位及两边取放货物的情况。而且,通过采用底层组件、中层组件及上层组件层层滑动的结构,使得叉取货物时的行程更长,并只需一个马达即可驱动中层组件和上层组件同时动作,结构巧妙,成本低。
