[0028] Working principle:
[0029] When the ultra-thin four-way vehicle structure is in use, the servo motor 14 is driven by the lifting and reversing drive to make the four-way vehicle in the middle position. At this time, the main rail travel driving wheel 5 and the main rail travel driven wheel 6 are both in a suspended state. At this time, the four-way vehicle can be carried out without load in the direction of the sub-rail shelf 21. When the four-way vehicle is in a cargo-carrying operation state on the sub-rail shelf 21, the servo motor 14 is driven by the lifting and reversing drive to make the four-way vehicle in a high position. At this time, the cargo pallet 19 and the cargo are lifted to separate the cargo pallet 19 and the cargo from the contact surface of the sub-rail shelf 21. The main rail travel driving wheel 5 and the main rail travel driven wheel 6 are both in a suspended state and do not contact the main rail 20. At this time, the four-way vehicle can be carried out on the sub-rail shelf 21.
[0030] When the four-way vehicle is running on the main track 20, the servo motor 14 is driven by the lifting and reversing to make the four-way vehicle in a low position. At this time, the sub-track driving wheel 12 and the sub-track driven wheel 13 are both suspended in the air and do not contact the track of the sub-track shelf 21. The main track driving wheel 5 and the main track driven wheel 6 are in contact with the main track 20. At this time, the loaded and unloaded states are in the same state, thereby realizing the operation on the main track 20.
