Description

Technical Field

[0001] This application relates to the field of container loading and unloading control technology, and in particular to a container train loading and unloading system and method. Background Technology

[0002] Currently, the volume of railway container transport is relatively low. On the one hand, railway container transport is time-consuming. In traditional railway container transport, freight trains need to undergo marshalling operations at the marshalling yards they pass through, that is, after being disassembled, they are reassembled with freight trains heading to the same destination. Due to the long waiting time for marshalling, railway transport is slow and the turnover of railway freight trains is slow. On the other hand, the loading and unloading speed of railway containers is slow.

[0003] Currently, railway container handling equipment mainly includes rail-mounted gantry cranes and reach stackers. Rail-mounted gantry cranes require loading and unloading containers one by one, and the power contact network of electrified railways can affect container lifting. Using existing railway container handling equipment requires freight trains to be diverted and rerouted to stations without power contact networks to load and unload containers, resulting in low efficiency. In addition, different railways may have different track gauges, especially in cross-border transport, where all containers need to be lifted between trains on different tracks, leading to low coordination.

[0066] In this embodiment of the invention, a standard container train rapid loading and unloading system is installed beside a railway line, allowing direct connection to standard container trains for loading and unloading containers. Based on the functions of the various areas where the standard container train rapid loading and unloading system is located, the area can be divided into the following zones: a railway container loading and unloading area, a container stacking area, and a container truck loading and unloading area, such as... Figure 1 As shown.

[0067] The railway container loading and unloading area is the area where standard container trains run and stop, allowing for container loading and unloading. 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 run, allowing for container loading and unloading.

[0068] The structure of the standard container train rapid loading and unloading system is as follows: Figures 1 to 3 The diagram shows a standard container train rapid loading and unloading system from different angles, including the standard container train, the power contact network, the power contact network translation mechanism, and the tandem bridge cranes. The standard container train is used to transport containers, and the power contact network is driven by the power contact network translation mechanism, which is mounted on the crane supports. The tandem bridge cranes consist of several bridge cranes arranged side-by-side along the railway, used for loading, unloading, and transferring containers between the railway container loading / unloading area, container stacking area, and container truck loading / unloading area. Existing bridge crane devices can be directly used.

[0069] In this embodiment, when a container truck carrying a container enters the container truck loading / unloading area, the spreader of the tandem overhead crane is moved to the container truck loading / unloading area, and the spreader of the overhead crane is lifted and moved to the container stacking area, where it is then lowered. When an empty container train enters the railway container loading / unloading area, the power contact network translation mechanism is controlled to move the power contact network to the side of the container train; the spreader of the tandem overhead crane is controlled to move to the container stacking area; the spreader of the overhead crane is controlled to lift containers to the railway container loading / unloading area and lower them onto the standard container train; the power contact network translation mechanism is controlled to move the power contact network above the standard container train, so that the standard container train can leave the railway container loading / unloading area. This avoids interference with the railway's power contact network, allows loading and unloading directly above the standard container train, and enables simultaneous loading and unloading of all containers on the standard container train, achieving rapid loading and unloading of railway containers and improving loading and unloading efficiency and coordination.

[0070] The following will be combined with the appendix Figure 4 This application provides a detailed description of the container train loading and unloading method provided in its embodiments. This method can be implemented using a computer program and can 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 utility application.

[0071] Please see Figure 4 This is a flowchart illustrating a container train loading and unloading method as provided in this application embodiment. Figure 4As shown, the method in this application embodiment may include the following steps:

[0072] S101, when it is detected that a container truck carrying a container enters the container truck loading and unloading area, controls the spreader of the tandem bridge crane to move to the container truck loading and unloading area, controls the spreader of the bridge crane to lift the container and move it to the container stacking area, and lowers the container to the container stacking area.

[0073] S102, when a container train is detected entering the railway container loading and unloading area empty, the power contact network translation mechanism is controlled to drive the power contact network to move to the side of the container train.

[0074] S103, controls the movement of the spreader of the tandem overhead crane to the container stacking area;

[0075] S104, control the spreaders of the bridge crane to lift the containers to the railway container loading and unloading area, and then lift the containers onto the standard container train;

[0076] S105 controls the power contact network translation mechanism to drive the power contact network 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: Standard container trains carrying containers enter the railway container loading and unloading area; the power contact network translation mechanism drives the power contact network to the side of the standard container train; the spreaders of the tandem overhead cranes travel to the railway container loading and unloading area, and the spreaders of the tandem overhead cranes lift the containers to be unloaded to the container stacking area; container trucks enter the container truck loading and unloading area; the spreaders of the tandem overhead cranes travel to the container stacking area, and the spreaders of the tandem overhead cranes lift the containers to be loaded and unloaded to the container trucks; the container loading process is as follows: container trucks carrying containers enter the container truck loading area. Unloading area; the spreaders of the tandem overhead cranes travel to the container truck loading and unloading area, lifting containers to the container stacking area and then lowering them onto the standard container train; the standard container train enters the railway container loading and unloading area empty; the power contact network translation mechanism moves the power contact network to the side of the standard container train; the spreaders of the tandem overhead cranes travel 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 contact network translation mechanism moves the power contact network above the standard container train. The standard container train departs from the railway container loading and unloading area.

[0078] For example Figure 5As shown, this paper presents a loading and unloading example of standard container trains with different track widths. The container loading and unloading process is as follows: Standard container train 1, loaded with containers, enters the railway container loading and unloading area; Standard container train 2, empty, enters the railway container loading and unloading area; The overhead contact line translation mechanisms above the two trains drive the overhead contact lines to the side of the standard container trains; The spreaders of the tandem bridge cranes move above standard container train 1, and the spreaders of the tandem bridge cranes lift the containers to be loaded and unloaded onto standard container train 2, and then lower the containers onto standard container train 2; The overhead contact line translation mechanisms above the two trains drive the overhead contact lines to the top of the standard container trains. The two standard container trains then leave the railway container loading and unloading area.

[0079] For example Figure 6 As shown, this invention provides a loading and unloading example for a standard container train without a power contact network translation mechanism. In this embodiment, a rapid loading and unloading system for standard container trains is installed alongside the railway line, allowing direct docking with standard container trains for loading and unloading containers. Based on the functions of each area where this rapid loading and unloading system is located, the area can be divided into the following zones: a railway container loading and unloading area, a container stacking area, and a container truck loading and unloading area, such as... Figure 1 As shown in the diagram. The railway container loading and unloading area is the area where standard container trains operate and stop; standard container trains can load and unload containers here. 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 operate; container trucks can load and unload containers here. The structure of this standard container train rapid loading and unloading system is as follows: Figure 5 As shown, the system includes standard container trains, an overhead contact line, and a row of bridge cranes. The standard container trains are used to transport containers, with electric locomotives at the front and rear. The pantograph of the rear locomotive is used to obtain power when entering the station, while the pantograph of the front locomotive is used to obtain power when leaving the station. The overhead contact line is located above the railway, but there is no overhead contact line in the loading and unloading area. The row of bridge cranes consists of several bridge cranes arranged side-by-side along the railway, used for loading, unloading, and transferring containers between the railway container loading and unloading area, container stacking area, and container truck loading and unloading area. Existing bridge crane equipment can be used.

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

[0081] 1. Overall loading and unloading process:

[0082] The electric locomotive behind the standard container train raises the pantograph-loaded container and enters the railway container loading and unloading area;

[0083] The spreaders of the tandem bridge cranes travel to the railway container loading and unloading area, and the spreaders of the tandem bridge cranes lift the containers to be unloaded to the container stacking area.

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

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

[0086] The spreaders of the tandem overhead cranes travel to the container stacking area, and the spreaders of the tandem overhead cranes lift the containers to be loaded and unloaded onto the container trucks.

[0087] The container loading process is as follows:

[0088] Container trucks carrying containers enter the container truck loading and unloading area;

[0089] The spreaders of the tandem overhead cranes travel to the container truck loading and unloading area, lift the containers to the container stacking area, and then lower 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 unloaded;

[0091] The spreaders of the tandem overhead cranes travel to the container stacking area, lift the containers to be loaded to the railway container loading and unloading area, and then lower the containers onto the standard container train.

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

[0093] In this embodiment, when a container truck carrying a container enters the container truck loading / unloading area, the spreader of the tandem overhead crane is moved to the container truck loading / unloading area, and the spreader of the overhead crane is lifted and moved to the container stacking area, where it is then lowered. When an empty container train enters the railway container loading / unloading area, the power contact network translation mechanism is controlled to move the power contact network to the side of the container train; the spreader of the tandem overhead crane is controlled to move to the container stacking area; the spreader of the overhead crane is controlled to lift containers to the railway container loading / unloading area and lower them onto the standard container train; the power contact network translation mechanism is controlled to move the power contact network above the standard container train, so that the standard container train can leave the railway container loading / unloading area. This avoids interference with the railway's power contact network, allows loading and unloading directly above the standard container train, and enables simultaneous loading and unloading of all containers on the standard container train, achieving rapid loading and unloading of railway containers and improving loading and unloading efficiency and coordination.
