The invention relates to a pallet fork system of a stacking machine, in particular to a safety type multi-stage pallet fork for a stacking machine. The safety type multi-stage pallet fork for the stacking machine comprises a cargo carrying table base and further comprises a telescopic pallet fork unit, a driving unit and a pallet fork tail end detection unit which are arranged on the cargo carrying table base, wherein the driving unit is connected with the telescopic pallet fork unit and used for driving the telescopic pallet fork unit to stretch out and draw back; and the tail end detection unit is connected with the telescopic pallet fork unit and used for detecting the telescopic displacement of the telescopic pallet fork unit. The telescopic pallet fork unit comprises a lower-layer pallet fork, a middle-layer pallet fork and an upper-layer pallet fork which are sequentially connected in a sliding mode, the lower-layer pallet fork is connected with the cargo carrying table base, andthe upper-layer pallet fork is connected with the pallet fork tail end detection unit. The safety type multi-stage pallet fork for the stacking machine has high safety and reliability, and can improve safety of equipment operation under the working conditions that the position of a tray object is abnormal or a transmission mechanism is accidentally damaged due to mechanical fatigue.

    本发明涉及堆垛机货叉系统,特别涉及一种安全型堆垛机用多级货叉。包括载货台基座及设置于载货台基座上的伸缩货叉单元、驱动单元及货叉末端检测单元,其中驱动单元与伸缩货叉单元连接,用于驱动伸缩货叉单元进行伸缩;末端检测单元与伸缩货叉单元连接,用于检测伸缩货叉单元的伸缩位移。伸缩货叉单元包括依次滑动连接的下层货叉、中层货叉及上层货叉,其中下层货叉与载货台基座连接,上层货叉与货叉末端检测单元连接。本发明具有高度安全可靠性,可避免在托盘对象位置异常或传动机构意外机械疲劳损伤等工况下设备运行的安全性。
