The loading or unloading improves the transshipment efficiency of the underground pipeline transportation of goods.

Further, the transmission direction of the automatic loading and unloading platform 210 is perpendicular to the running direction of the bogie 4. During the operation of the logistics transport vehicle, the rotating stick receives the axial force without receiving the rotational moment, thereby ensuring that the logistics transport vehicle rotates the stick during the running process.

When the cargo container is placed on the automatic loading and unloading platform 210, the limit motor drives the rack and pinion mechanism to work, and the rack drives the limit stop to rise above the position of the rotating stick, so that the cargo container is limited to In the surrounding limit stop, the logistics truck is prevented from running during the operation, and the cargo pallet slides out of the automatic loading and unloading platform 210. In addition, there is another operation mode: after the logistics transport vehicle is docked to the loading and unloading station, the rotating stick of the automatic loading and unloading platform 210 is docked with the transport roller lane of the loading and unloading station, and the limit device of the opposite side of the transport roller lane is limited. The stopper rises and the other limiting devices remain in the initial state, so that when the cargo container is transported from the transport roller to the rotating roller, the raised limit stop can prevent the cargo container from slipping out due to inertia. The automatic loading and unloading platform 210, when the cargo container is placed on the automatic loading and unloading platform 210, the other limiting devices work to raise the limit stop of the other loading and unloading platform 210 in other directions.
