Description

Technical Field

[0001] The utility model relates to a container cover shipping platform and a railway transportation system, belonging to the technical field of railway transportation systems. Background Art

[0002] Railways are important national transportation infrastructure and a major livelihood project. In order to achieve a pendulum-like mode of transport in the railway field, a detachable container cover can now be additionally provided on the traditional open-top container, expanding the transport capacity of the open-top container. For example, the Chinese patent document CN216508328U previously applied for by the applicant discloses a railway transportation system in which multiple open-top containers are respectively fixed on multiple freight flatbeds of a freight train. The open-top containers can be used to transport production raw materials to the factory area. After arriving at the factory area, the operators unload the production raw materials, and then the container cover can be fastened to the open-top container to form a closed structure. The closed structure can be used to transport waste materials such as fly ash. The container covers can be stacked and palletized on some freight flatbeds for transportation. In addition, the freight flatbeds can also be loaded with finished steel coils for transportation out of the factory area. However, in this conventional transportation method, container covers are usually stacked directly on freight flatbed trucks, and the container covers need to be loaded one by one, which increases the waiting time of the train. In addition, each container top cover needs to be additionally provided with locking corner pieces to lock the upper and lower adjacent container top covers, which increases the production cost of the container top covers.

When multiple folded container cover shipping platforms 10 are stacked, the locking corner pieces 15 of the upper container cover shipping platform can be locked to the container corner pieces 16 of the lower container cover shipping platform through the container twist locks 151. Figure 13 As shown, a plurality of container cover shipping racks 10 in a folded state can be stacked and placed, thereby enabling centralized storage and transportation.

[0050] The present invention also provides a railway transportation system comprising a freight train, an open-top container, a container cover, and the aforementioned container cover loading platform 10. The freight train includes multiple freight flatbed trucks, the open-top containers being secured to the trucks, and the container covers being detachably mounted on the open-top containers, capable of snapping onto the open-top containers to seal them. When transporting raw materials to a factory, the raw materials can be placed in the open-top containers for transportation. Upon arrival at the factory, workers unload the raw materials and then snap the container covers onto the open-top containers to form a closed structure, which can be used to transport waste materials such as fly ash. The container cover loading platform 10 is secured to the freight flatbed trucks via locking angle fittings 15, and multiple container covers can be stacked on the container cover loading platform 10. Furthermore, the container cover loading platform 10 is provided with a coil steel support 14, which can be used to load and transport coil steel upon arrival at the factory.
