Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to a multi-layered intelligent logistics vehicle for ports. Background Art

[0002] Port logistics is an important part of cargo transportation. In recent years, due to the flexibility of port logistics vehicles, they have played an important role in port logistics. This is because the cargo transportation volume of ports is relatively large. After the cargo ship docks at the port, in order to facilitate the transportation of goods, the staff will use logistics vehicles. Specifically, the containers are transferred from the cargo ship to the land, and then the material boxes in the container are dispersed to multiple logistics vehicles. The logistics vehicles then transfer the material boxes to the designated location as needed, thereby completing the rapid and effective dispersion of the goods in the port container.

[0003] However, when the material truck is loading and unloading the logistics boxes in the container, due to the convenience of the logistics truck, the vehicle body is relatively small. When a forklift is used to transfer the goods in the container to the logistics truck, the amount of each transfer is relatively small, which makes the utilization rate of the forklift not high, but increases the cost. In addition, some logistics boxes are at a higher risk during the transfer process with a forklift, so the loading and unloading of goods on the logistics truck is carried out manually, and a trolley can be used for transportation during manual transportation. However, when loading and unloading to the logistics truck, workers are required to lift and transport the material boxes, which has a relatively high labor intensity and a relatively low loading and unloading efficiency. At the same time, the material boxes are not placed neatly during loading and unloading, which leads to an increase in subsequent labor. Summary of the invention

The rotating disk 30 drives the turning roller 20 to perform intermittent movement through the turning shaft 22, so that the turning roller 20 drives the material box in the turning hole 21 to perform intermittent rotation. At this time, the worker can directly take the material box on the turning roller 20 on the logistics car 10, and the worker does not need to carry it up and down at the rear of the logistics car; Similarly, when unloading the material truck, the worker inserts the logistics box into the flipping hole 21 on the logistics carriage 10, and the material box on the flipping hole 46 realizes intermittent rotation through the rotating disk 30 and the semi-rotating wheel 31. When it runs to one side of the adsorption disk 63, it cooperates with the electric telescopic rod 62 to realize grabbing, and then realizes the downward flipping through the rotating shaft 54, the driving rod 52, the swing rod 51 and the Z-shaped flipping rod 45, so that the adsorption disk 63 drives the material box to flip into the U-shaped positioning plate 66 to complete the neat unloading.
