Description

Container transport device and transport method {CONTAINER TRANSPORTING APPARATUS AND METHOD}

The present invention relates to a transportation device of a container, and more particularly to a container transportation device that can be used in a mobile port or an automatic container unloading system to transport or deliver a container.

Maritime transportation using ships as a means of moving goods between remote areas uses less energy than other means of transportation and the transportation cost is low, making up a large part of international trade.

Recently, in the sea transportation using a container, a large sized ship is used to improve the efficiency of transportation, which is to secure the economics of transportation by increasing the amount of transportation of the vessel. As a result, more ports and ports are required to dock large vessels and to unload containers.

However, harbors that can dock large container ships are limited at home and abroad, and the construction of such ports requires a lot of expenses due to dredging to maintain the required port depth, as well as a large place. In addition, due to the construction of a large port has a lot of influence on the surrounding environment, such as causing a traffic jam or destruction of the coastal environment, there are many restrictions on the construction of a large port.

Therefore, there is a need for the development of a new system that can unload cargo at sea offshore, without having to dock a large vessel on the quay of a seaport on land. Patent invention (registration number 10-0895604) regarding the cargo transfer method used was received. 1 and 2 is a view showing a schematic view of the mobile port shown in the patent. The floating port mobile harbor 10 can be unloaded by using the crane 20, Figure 1 is unloading between the mobile port 10 and the large container ship 30, Figure 2 is a mobile port The unloading between 10 and the land pier 40 is shown.

The unloading of containers such as containers according to the prior art between the mobile harbor 10 and the land pier 40 is generally an operation in which one crane intermittently transports one container. There is a problem that is consumed.

3 is a view schematically showing a state of performing container unloading by using a crane installed in a mobile harbor. Here, the longitudinal direction and the longitudinal direction and the X direction, the width direction and the transverse direction and the Y direction, and the vertical direction and the Z direction of the mobile harbor 10 indicate the same direction. When the crane 20 unloads the container C between the container ship 30 or the land pier 40 using the spreader 80, the container C is fastened to the spreader 80. It moves along the direction of the arrow shown in the figure.

In this case, the spreader 80 or the crane 20 loads the container C at a desired position on the mobile harbor 10 only after repeating several transverse, longitudinal and vertical movements. In addition, the spreader 80 can then start the unloading work for the next container only after repeating several movements again through the reverse process.

Therefore, the unloading operation by the crane 20 only takes a long time and there is a problem that the work efficiency is low, it is necessary to solve this. In addition, when the crane 20 itself moves, the center of gravity of the mobile harbor 10 is changed, so that it is difficult to maintain the equilibrium, and there is a problem that unloading is delayed.
