Description

Technical Field

[0001] The present invention relates to the technical field of terminal transportation facilities, and in particular to a three-dimensional port container operation system. Background Art

[0002] With the continuous development and maturity of automated container terminal yard automation equipment and technology, especially the continuous application of autonomous driving technology, more and more newly built container terminals (logistics yards, train loading and unloading yards) use automated operation modes for yard operations, and yard (yard) operations use automated rail-mounted container gantry cranes (abbreviated as automated rail cranes or ARMGs). The port roads are arranged at level crossing, which cannot completely solve the separation of internal and external container trucks, resulting in the interweaving of internal and external container trucks. When the internal container truck adopts the unmanned driving mode, there are safety issues under the technical conditions and policy requirements of the existing unmanned container trucks. When the traffic volume of both internal and external container trucks is large, it seriously affects the efficiency of the loading and unloading system.

[0003] The existing automated terminal yard (station) layout mainly includes the following types:

[0004] (1) The yard operation line is arranged perpendicular to the wharf shoreline. The yard loading and unloading operation adopts the cantilever-free ARMG. The inner and outer container trucks are handed over on the sea and land sides to achieve the separation of the inner and outer container trucks. This layout is suitable for terminals (yards) without transshipment or with a small transshipment ratio. For terminals (yards) with a high transshipment ratio, it will seriously affect the equipment utilization efficiency and operation efficiency;

[0005] (2) The yard operation line is arranged perpendicular to the wharf shoreline. The yard loading and unloading operation adopts a combination mode of non-cantilever ARMG + single (double) cantilever ARMG. The inner container truck is handed over at the sea side handover area and under the cantilever, and the outer container truck is handed over at the land side handover area and under the cantilever, so as to achieve the separation of the inner and outer container trucks. This layout can adapt to a certain transfer ratio, but the number of inner container trucks increases, the control system is complex, and the system capacity is greatly affected;

[0006] (3) The yard operation line is arranged parallel to the wharf shoreline. The yard loading and unloading operations use single (double) cantilever ARMG or ARTG. The inner and outer container trucks are connected inside the span or under the cantilever. The roads in the port (yard) are arranged at level crossing, which makes it impossible to separate the inner and outer container trucks.

[0007] It can be seen that the current layout of automated terminal yards (stations) has the following shortcomings: (1) Automated terminals arranged perpendicular to the terminal shoreline achieve the separation of internal and external container truck traffic, but cannot adapt to situations with a large transshipment ratio, otherwise it will have a significant impact on equipment efficiency and system efficiency; (2) Automated terminals arranged parallel to the terminal shoreline cannot achieve the separation of internal and external container truck traffic. There is interference between internal and external container truck traffic, which affects traffic efficiency and operating efficiency. At the same time, there are major safety hazards, especially when the internal container truck adopts the automatic driving mode, the safety risk is even greater. (3) The internal traffic organization is intertwined, causing traffic congestion on social roads around the yard (station). Summary of the invention

[0008] The main purpose of the present invention is to provide a three-dimensional port container operation system to solve the problem in the prior art that the internal and external container trucks of an automated terminal with a large transfer ratio cannot be effectively separated.

[0010] Furthermore, the cantilever rail crane is a double-cantilever rail crane, and the two cantilevers of the double-cantilever rail crane are respectively located above the outer container truck transport road and above the inner container truck transport road.

[0011] Furthermore, the outer container truck transport road includes a first loop road and a plurality of first longitudinal roads connecting two opposite sides of the first loop road; the inner container truck transport road includes a second loop road and a plurality of second longitudinal roads connecting two opposite sides of the second loop road.

[0012] Furthermore, the first longitudinal road and the second longitudinal road are arranged in parallel, a road gap is formed between two adjacent second longitudinal roads, and the plurality of first longitudinal roads are located under the plurality of road gaps in a one-to-one correspondence.

[0014] Further, the yard area is arranged between the adjacent first longitudinal road and the second longitudinal road.

[0015] Furthermore, the second longitudinal road includes three lanes, the ones on both sides are working lanes, and the one in the center is a driving lane.

[0016] Furthermore, the second ring road includes two fast lanes and two slow lanes.

[0017] Furthermore, the inner container truck transport road also includes a plurality of third longitudinal roads connecting the opposite sides of the first loop road, the third longitudinal roads are parallel to the first longitudinal roads and are located directly below the second longitudinal roads, and the third longitudinal roads include parking lanes and driving lanes.
