The shuttle vehicle 6 runs to the railway container loading area 4 (which can be arranged at the side of the railway track 3) in the railway operation area, the railway rail-mounted crane 2 picks up the container from the shuttle vehicle 6 and places it on the designated position of the railway container loading area 4, and the shuttle vehicle 6 returns to the lower end of the elevated rail 8 to continue to interact with the elevated rail-mounted crane 7.

[0041] (3) Railway loading operation.

[0042] After the train car 21 drives into the railway operation area, the railway rail-mounted crane 2 lifts the container from the railway container loading and unloading area 4 and places it into the train car 21, and the railway loading operation is completed.

[0043] The shuttle vehicle 6 can also interact with the railway track crane 2 at the position after running to the railway operation area, and the railway track crane 2 grabs the container from the shuttle vehicle 6 and places it into the train carriage 21 to complete the railway loading operation.

[0050] The specific port loading operation is implemented according to the existing technology, which is not limited in the present application.

[0051] In the automatic port intermodal transport system of the present application, the port yard and the railway are connected to each other through the elevated track, the railway track crane interacts with the train carriage in the railway operation area to transfer containers, the high-speed shuttle vehicle realizes the transfer of containers between the railway and the elevated track, the containers are transferred to the intermodal interaction area through the elevated track and interact with the horizontal transport vehicle in the port operation area, and the horizontal transport vehicle directly interacts with the yard track crane at the side of the port yard. Through the above structure, the transfer of containers between the railway and the port is realized, the elevated track does not occupy ground space and does not interfere with other transport vehicles in the port, and the efficiency of intermodal transport can be significantly improved.

[0052] In some embodiments of the present application, the sea-rail intermodal system is further provided with a railway external truck lane 11 intersecting with the elevated track 8, and the area where the two intersect is defined as the railway external truck loading and unloading area 10. The external truck 13 driving on the railway external truck lane 11 directly enters the railway external truck loading and unloading area 10 to interact with the elevated track crane 7, so that the containers transported by land can be transported by rail or by sea based on the sea-rail intermodal system of the present application. When carrying out the container receiving operation at the port, the containers that need to be transported by land can be directly transported by land through the interaction between the elevated track crane 7 and the external truck 13, while the containers that need to be transported by rail are transported by rail through the interaction between the elevated track crane 7 and the shuttle car 6. When carrying out the container sending operation at the port, the containers sent by land from the external truck 13 can be transported to the port yard through the interaction between the elevated track crane 7 and the external truck 13, the interaction between the elevated track crane 7 and the horizontal transport vehicle 15. When carrying out the container sending operation by rail, the containers sent by land from the external truck 13 can be transported to the railway through the interaction between the elevated track crane 7 and the external truck 13, and the interaction between the shuttle car 6 and the elevated track crane 7. When carrying out the container receiving operation by rail, the containers that need to be transported by land can be transported by land through the interaction between the shuttle car 6 and the elevated track crane 7, and the interaction between the elevated track crane 7 and the external truck 13.

[0053] The railway external truck lane 11 is connected with the yard external truck loading and unloading lane 20 in the port operation area (connected through the truck lane 12 in the figure), so that the external truck 13 can send the loaded containers to the railway side through the transfer of the elevated track crane 7, and the containers on the railway side can be sent to the port yard 16 through the transfer of the elevated track crane 7 and the external truck 13.

[0054] In some embodiments of the present application, a railway temporary yard 9 is arranged under the elevated track 8 to temporarily store containers, so as to improve the operation efficiency of the high-speed track crane 7. At least two elevated track cranes 7 are arranged on the elevated track 8. In the container receiving operation by rail (including receiving containers from the port and receiving containers from land), one elevated track crane 7 takes the container from the horizontal transport vehicle 15 or the external truck 13, places the container in the railway temporary yard 9, and then performs the next operation. When the shuttle car 6 runs to the elevated track 8, the other or idle elevated track crane 7 takes the container from the railway temporary yard 9 and places it on the shuttle car 6. In the container sending operation by rail (including sending containers to the port and sending containers to land), one elevated track crane 7 takes the container from the shuttle car 6 and places it in the railway temporary yard for storage, and then performs the next operation. When the container needs to be sent to the port or land, the other or idle elevated track crane 7 takes the container from the railway temporary yard 9 and runs to the intermodal interaction area 19 to interact with the horizontal transport vehicle 15 or runs to the railway external truck loading and unloading area 10 to interact with the external truck 13.

[0055] In some embodiments of the present invention, both the overhead rail crane 7 and the yard rail crane 17 are equipped with a rotating spreader or a rotating trolley. The rotating spreader or rotating trolley is used to change the orientation of containers facing different directions, so as to meet the loading and unloading needs of railways and docks and improve operational efficiency.

[0056] In some embodiments of the present invention, the elevated track 8 and the yard track are designed as a double-layer operating structure. Taking the elevated track 8 as an example, for instance... Figure 2 As shown, in the double-layer track structure, each layer is equipped with at least one overhead rail gantry crane 7. The lower-layer overhead rail gantry crane 7 is used for interaction with the shuttle car 6, while the upper-layer overhead rail gantry crane 7 is used for interaction with the horizontal transport car 15 or the external container truck 13. Both layers of overhead rail gantry cranes 7 can operate in the railway temporary storage yard 9. Taking the storage yard track as an example, during the interaction between the lower-layer storage yard rail gantry crane 17 and the horizontal transport car 15 or the external container truck 13, the upper-layer storage yard rail gantry crane 17 completes the previous operation and enters the next operation, thereby significantly improving the efficiency of storage yard operations. As described above, the upper and lower layers of overhead / storage yard rail gantry cranes adopt avoidance measures to avoid operational conflicts.

[0057] It should be noted that the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
