Abstract

PURPOSE:To make the operation of efficient cargo handling attainable in the water area where seawater is deep enough, by installing a freight car line circulating around the shore and sea in a loop form via a steel bridge built at sea, while setting up handling terminals on the sea and also handling facilites on the shore at plural spots, respectively. CONSTITUTION:A ship S is berthed in the vicinity of a handling terminal 4 for unloading use, and an arm 6 is turned round whereby it is situated in parallel with the ship. After the specified turning motion is over, a float 7 is filled up with water, then seated on the seabed, and unloading takes place by a crane installation 14. And, cargoes are all stowed in a temporary storage tank 5 via a conveyor 13 and then loaded in a freight car 3 in regular sequence via a hopper 8. Cargoes in the freight car 3 are unloaded by an unloader 27 and fed to a storage yard or the like through conveyors. In addition, in case of loading, these cargoes are loaded on the freight car 3 by the unloader 27, and finally discharged from the freight car 3 to a temporary storage tank 20 at the handling terminal 4. With this, these cargoes are discharged out on the conveyor and efficiently projected through a chute into a hold of the ship S berthed beneath this chute.

Description

[Detailed description of the invention] The present invention relates to the creation of a cargo handling station for ships.

In recent years, there has been a tendency for ships to transport ore, grain, etc. by sea to become larger, but the lack of port facilities for cargo handling, such as shallow ports, is one of the factors that prevents ships from becoming larger. It has become. Conventionally, countermeasures have been taken to deal with such problems, such as laying down the port or constructing a pier, but this method
Although the construction requires a large amount of labor and expense, the cargo handling equipment obtained is hardly sufficient for efficient cargo handling.

The present invention was devised in view of the above circumstances, and aims to provide a cargo handling base that can efficiently handle cargo from a large number of ships. A loop-shaped freight car running line will be established so that freight cars can circulate between land and sea via a railway bridge, and cargo handling terminals will be installed at multiple locations on the freight car running line at sea, and multiple freight car running lines on land will be installed. Its basic feature is that the location is equipped with cargo handling equipment for freight cars.

An embodiment of the present invention will be described below with reference to the drawings.

The cargo handling base of the present invention is provided with a loop-shaped freight car running line 1 that allows freight cars to circulate and run on land and on the sea. For this reason, a steel bridge 2 has been constructed over the sea. In this embodiment, the freight car running line 1 is formed so that the sea portion and the land portion each swell into a ring shape. On such a freight car traveling line 1, freight cars circulate and travel. In this embodiment, the freight cars 3 are arranged in an endlessly connected manner over the entire length of the loop-shaped line, and can travel in circulation while being connected.
