In particular, the AGV fork arm trolley integrates the automatic pick-and-place function of goods, greatly improving the efficiency and accuracy of warehouse operations. However, the operation process of the existing AGV fork arm trolley is often complicated when performing maintenance, overhaul or replacing the fork arm. The specific steps for removing the fork arm are: raising the lifting mechanism or removing the fork arm cover, then disassembling the fork arm motor cover and the fork arm tail cover, removing the drag chain mounting parts, and finally pulling out the plug-in terminals. Only then can the fork arm be completely separated from the drag chain. Only after all the above steps are completed can the fork arm be completely separated from the drag chain. The whole process is cumbersome and time-consuming.
