[0004] However, the device is not convenient for transporting railway containers. Since the railway containers are wider than ordinary containers, when the railway containers are loaded on ordinary container ships, because the gap between adjacent sea containers is small, after a railway container is loaded on the ship, in addition to occupying the entire position of an ordinary container, it will also occupy part of the position of adjacent containers on both sides. Therefore, the railway containers cannot be stacked side by side like ordinary containers, which will affect the number of containers stacked on the ship. Therefore, a container loading conversion connector is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a container loading conversion connector in view of the deficiencies in the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a container loading conversion connector, including a container conversion connector, a ship hatch cover, a special container, and an ordinary container.
