Description

Container train loading and unloading system and method Technical Field

[0001] The present application relates to the technical field of container loading and unloading control, and in particular to a container train loading and unloading system and method. Background Art

[0002] Currently, rail container transport volume is low. For one thing, rail container transport takes a long time. In traditional rail container transport, freight trains must undergo unmarshaling operations at marshaling yards. This involves unmarshaling and re-marshaling freight trains destined for the same destination. This long marshaling wait time results in slow rail transport and freight train turnover. Furthermore, rail container loading and unloading is also slow.

[0003] Currently, railway container handling equipment primarily consists of rail-mounted gantry cranes and reach stackers. Rail-mounted gantry cranes require loading and unloading containers individually, and the overhead catenary system on electrified railways can interfere with container handling. Using existing railway container handling equipment requires freight trains to be shunted off and dispatched to stations without overhead catenary systems, resulting in low efficiency. Furthermore, track gauges may vary between railways, making cross-border transport, in particular, difficult because all containers must be hoisted between trains on different tracks.

[0066] In an embodiment of the present invention, a rapid loading and unloading system for standard container trains is installed alongside a railway line and can directly connect to standard container trains for loading and unloading containers. Based on the functions of the various areas within the system, the area can be divided into the following areas: a railway container loading and unloading area, a container stacking area, and a container truck loading and unloading area, as shown in Figure 1.

[0067] The railway container loading and unloading area is where standard container trains travel and dock. Standard container trains docked at the railway container loading and unloading area can load and unload containers. The container stacking area is a temporary storage area where containers are transferred to standard container trains or container trucks. The container truck loading and unloading area is where container trucks travel and dock. Container truck loading and unloading areas are where container trucks travel and dock.

[0068] Figures 1 to 3 illustrate the structure of the standard container train rapid loading and unloading system, showing schematic diagrams from different angles. The system comprises a standard container train, an electric contact line, an electric contact line translation mechanism, and a tandem bridge crane. The standard container train transports containers. The electric contact line is driven by the electric contact line translation mechanism; the electric contact line translation mechanism is mounted on a crane support. The tandem bridge crane consists of several bridge cranes arranged in parallel along the railway, used to load, unload, and transfer containers between the railway container loading and unloading area, the container stacking area, and the container truck loading and unloading area. The bridge cranes can be directly adapted from existing bridge container cranes.

[0069] In an embodiment of the present application, when a container truck carrying a container enters a container truck loading and unloading area, the gantry crane's spreader is controlled to move to the container truck loading and unloading area, the gantry crane's spreader is controlled to lift the container and move it to the container stacking area, and the container is lowered to the container stacking area. When an empty container train enters a railway container loading and unloading area, the power contact network translation mechanism is controlled to drive the power contact network to the side of the container train. The gantry crane's spreader is controlled to move to the container stacking area. The gantry crane's spreader is controlled to lift each container to the railway container loading and unloading area, and the container is lowered to the standard container train. The power contact network translation mechanism is controlled to drive the power contact network above the standard container train to drive the standard container train away from the railway container loading and unloading area. This avoids interfering with the railway's power contact network, allows loading and unloading to be performed directly above the standard container train, and allows all containers on the standard container train to be loaded and unloaded simultaneously, thereby achieving rapid loading and unloading of railway containers and improving loading and unloading efficiency and coordination.

[0070] The following, in conjunction with Figure 4, details the container train loading and unloading method provided by an embodiment of the present application. This method can be implemented using a computer program and run on a container train loading and unloading system based on the von Neumann architecture. This computer program can be integrated into an application or run as a standalone tool application.

[0071] Please refer to Figure 4, which is a flow chart of a container train loading and unloading method according to an embodiment of the present application. As shown in Figure 4, the method according to the embodiment of the present application may include the following steps:

[0072] S101, when a container truck carrying a container enters the container truck loading and unloading area, controlling the spreader of the bridge crane to move to the container truck loading and unloading area, controlling the spreader of the bridge crane to lift the container and move it to the container stacking area, and then lowering the container to the container stacking area;

[0073] S102, when it is detected that an empty container train enters the railway container loading and unloading area, controlling the power contact network translation mechanism to drive the power contact network to move to the side of the container train;

[0074] S103, controlling the spreader of the tandem bridge crane to move to the container stacking area;

[0075] S104, controlling the lifting devices of the bridge crane to lift the containers to the railway container loading and unloading area, and then lowering the containers to the standard container train;

[0076] S105, controlling the electric contact network translation mechanism to drive the electric contact network to above the standard container train, so as to drive the standard container train away from the railway container loading and unloading area.

[0077] In one possible implementation, the overall loading and unloading process is as follows: a standard container train carrying containers enters the railway container loading and unloading area; the electric contact network translation mechanism drives the electric contact network to the side of the standard container train; the slings of the tandem bridge cranes respectively move to the railway container loading and unloading area, and the slings of the tandem bridge cranes respectively lift the containers to be unloaded to the container stacking area; the container truck enters the container truck loading and unloading area; the slings of the tandem bridge cranes respectively move to the container stacking area, and the slings of the tandem bridge cranes respectively lift the containers to be loaded and unloaded to the container truck; the container loading process is as follows: the container truck carries the containers into the container truck loading and unloading area; the container truck enters the container truck loading and unloading area; the container truck enters the container truck loading and unloading area; the container truck enters the container truck loading and unloading area; the container truck enters the container truck loading and unloading area; the container truck enters the container truck loading and unloading area The cranes then move to the container loading and unloading area. The cranes' spreaders then move to the container truck loading and unloading area, lifting containers to the container stacking area and lowering them onto the container stacking area. The empty standard container train enters the railway container loading and unloading area. The power catenary translation mechanism drives the power catenary to the side of the standard container train. The cranes' spreaders then move to the container stacking area, lifting containers to be loaded to the railway container loading and unloading area and lowering them onto the standard container train. The power catenary translation mechanism drives the power catenary to the top of the standard container train. The standard container train then leaves the railway container loading and unloading area.

[0078] For example, as shown in Figure 5, a loading and unloading example of standard container trains with different track widths is provided. The container loading and unloading process is as follows: Standard container train 1 enters the railway container loading and unloading area with containers loaded; standard container train 2 enters the railway container loading and unloading area empty; the overhead contact network translation mechanisms above the two trains respectively drive the overhead contact network to the side of the standard container trains; the spreaders of the tandem cranes respectively move above standard container train 1, lift the containers to be loaded and unloaded, and then drop the containers onto standard container train 2; the overhead contact network translation mechanisms above the two trains respectively drive the overhead contact network to the top of the standard container trains. The two standard container trains then depart the railway container loading and unloading area.

[0079] For example, as shown in Figure 6, a loading and unloading example of a standard container train without an electric overhead line translation mechanism is provided. In an embodiment of the present invention, a standard container train rapid loading and unloading system is installed alongside a railway line, enabling direct docking with standard container trains to load and unload containers. Based on the functions of the various areas within the standard container train rapid loading and unloading system, the area where the system is located can be divided into the following areas: a railway container loading and unloading area, a container stacking area, and a container truck loading and unloading area, as shown in Figure 1. The railway container loading and unloading area is the area where standard container trains travel and dock, where standard container trains dock and load and unload containers. The container stacking area is a temporary storage area where containers are transferred to standard container trains or container trucks. The container truck loading and unloading area is the area where container trucks travel and where container trucks dock and load and unload containers. The structure of the standard container train rapid loading and unloading system is shown in Figure 5, and includes a standard container train, an electric overhead line, and a tandem gantry crane. Standard container trains are used to transport containers, with electric locomotives at the front and rear. The pantograph of the rear electric locomotive is used to obtain electricity when entering the station, while the pantograph of the front electric locomotive is used to obtain electricity when leaving the station. The power contact network is located above the railway, and there is no power contact network in the loading and unloading area. The row of bridge cranes consists of several bridge cranes arranged in parallel along the railway, which are used to load, unload and transfer containers between the railway container loading and unloading area, the container stacking area and the container truck loading and unloading area. The bridge cranes can use existing bridge container crane devices.

[0080] The working principle of the standard container train rapid loading and unloading system of this embodiment is as follows:

[0081] 1. Overall loading and unloading process:

[0082] The electric locomotive behind the standard container train raises the pantograph to carry the container into the railway container loading and unloading area;

[0083] The lifting devices of the tandem bridge cranes move to the railway container loading and unloading area, and the lifting devices of the tandem bridge cranes lift the containers to be unloaded to the container stacking area;

[0084] The electric locomotive in front of the standard container train raises its pantograph and leaves the railway container loading and unloading area;

[0085] Container trucks enter the container truck loading and unloading area;

[0086] The lifting devices of the tandem bridge cranes move to the container stacking area and lift the containers to be loaded and unloaded to the container trucks.

[0087] The container loading process is as follows:

[0088] The container truck carries the container into the container truck loading and unloading area;

[0089] The spreaders of the tandem bridge cranes move to the container truck loading and unloading area, lift the containers to the container stacking area, and drop the containers to the container stacking area;

[0090] The electric locomotive behind the standard container train raises its pantograph and enters the railway container loading and unloading area without any load;

[0091] The spreaders of the tandem cranes move to the container stacking area, lift the containers to be loaded to the railway container loading and unloading area, and drop the containers onto the standard container trains.

[0092] The electric locomotive in front of the standard container train raises its pantograph and leaves the railway container loading and unloading area.

[0093] In an embodiment of the present application, when a container truck carrying a container enters a container truck loading and unloading area, the gantry crane's spreader is controlled to move to the container truck loading and unloading area, the gantry crane's spreader is controlled to lift the container and move it to the container stacking area, and the container is lowered to the container stacking area. When an empty container train enters a railway container loading and unloading area, the power contact network translation mechanism is controlled to drive the power contact network to the side of the container train. The gantry crane's spreader is controlled to move to the container stacking area. The gantry crane's spreader is controlled to lift each container to the railway container loading and unloading area, and the container is lowered to the standard container train. The power contact network translation mechanism is controlled to drive the power contact network above the standard container train to drive the standard container train away from the railway container loading and unloading area. This avoids interfering with the railway's power contact network, allows loading and unloading to be performed directly above the standard container train, and allows all containers on the standard container train to be loaded and unloaded simultaneously, thereby achieving rapid loading and unloading of railway containers and improving loading and unloading efficiency and coordination.
