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 import ore, grain, etc. to be larger, but the lack of port facilities for cargo handling, such as the shallowness of the water in ports, is one of the factors that prevents ships from becoming larger. There is. Previously, countermeasures such as dredging the port and constructing a pier have been taken to deal with such problems.
This method involves costly civil engineering work, which requires large construction costs and long-term construction work. In addition, demurrage due to ship congestion is a major problem in some ports, but the above-mentioned conventional methods cannot be a very effective solution to this problem.

In view of these problems, it is an object of the present invention to provide a cargo handling base capable of efficiently and smoothly carrying out cargo handling operations by appropriately dealing with problems such as the increase in the size of ships and ship congestion.

For this reason, the present invention provides a terminal floating on the sea, a main conveyance line using a belt conveyor system that connects the terminal and a storage yard while being supported by a buoyant body, and a belt conveyor system that extends from the terminal while being supported by a buoyant body. Its basic feature is that it is equipped with a plurality of terminal conveyance lines and floating cargo handling equipment connected to the tip of each terminal conveyance line.

The present invention will be described below with reference to the drawings.

The present invention comprises a terminal (1) floating on the sea, a main conveyance line (2) using a belt conveyor system that connects the terminal (2) and a storage yard while being supported by a buoyant body, and Multiple end conveyance 2-in (3) by belt conveyor system extending from terminal (1)
and floating cargo handling equipment (4) connected to the tip of each terminal conveyance line. The present invention has substantial cargo handling equipment centered around the terminal (1) located offshore in deep water, with floating cargo handling equipment (4) located at the tip of the terminal (1).
) with a plurality of single-end transport lines (3) extending in all directions, it is possible to carry out cargo handling by a large number of ships in a wide offshore area, and furthermore, the terminal (1) and onshore storage The terminal (1) is connected to the yard (5) by a main conveyance line (2) using a belt conveyor system, and the terminal (1) is used as a relay base for cargo handling to each terminal conveyance line (3).
4.

The terminal (1) is floating at a suitable location on the sea, for example, at a relatively deep water location about 2 to 5 km offshore, and constitutes a transfer base for cargo to be handled. This terminal (1) is constructed to be able to float by incorporating a buoyancy tank, etc., and its displacement in the horizontal direction is restrained by multiple identification piles (6) installed on the surrounding seabed. , is floatingly installed so that it can only move up and down while being guided by this fixed vile.

The main transport engine (2) using the belt conveyor system is installed on land, etc., and is connected to the storage yard (5) and the terminal (2).
1), and as shown in Figures 4 to 6, the pipeline (8) floated by a buoyancy body (7) (in this example, a buoyancy tank) and the pipeline (8) disposed within this pipeline. It consists of multiple belt conveyors (9) installed. That is, the pipeline (8) V and both 111
It is composed of a plurality of connected tubes (81) each having a buoyancy body (7) attached to the i. The belt conveyor (9) is disposed within this pipeline (j). Some of these belt conveyors (9) are for unloading and others are for shipping, and the direction of conveyance is determined accordingly. In addition, in this implementation area, the buoyant body (7) is composed of both 111+1 of each 1J body (81).
The i7 design reduces the influence of waves, etc. In addition, the pipe body (81) rl at the terminal side end of the main conveyance line (2) is raised up to the terminal deck as shown in Figure 3, and the lower part of the rising part is connected to the terminal (1).
It is supported via a support frame 01 by a buoyant body (7) connected to the buoyancy body (7). Such a structure can prevent seawater etc. from flowing into the p-tube.

The '3' body (81) is connected in a l1lill manner 11. However, in order to absorb external forces caused by waves, etc., each tube can be flexibly connected to a 6-shaped tubular body, such as a bellows. An appropriate one having a vertically elongated circular shape can be used.

The pipeline floating on the sea surface (8) is fixed to the fixed pile θυ so that it can float up and down.

In this implementation 'V/1, the fixed bails 00 erected on both sides of each tube body (8J) are attached to the buoyant body (7) and inserted into the insertion holes of the fixtures (2). In other words, the pipeline (8) is restrained while allowing it to float in the vertical direction.

A plurality of terminal conveyance lines (3) using a belt conveyor system extending from the terminal (1) are basically the same as the main conveyance line (2), and a floating pipeline a+ to which a floating body 01 is attached. It consists of a Bell i and a conveyor α9 arranged within it. These terminal conveyance lines (3) are divided into two types, one for shipping and one for unloading, and the direction of conveyance is determined accordingly. In this example, (
3a) to (3d) are unloading lines, (3e) and (
3f) constitutes the shipping line.

In this embodiment, this terminal conveyance line (3) has a length of 19 meters from the terminal (1) as the main conveyance line (2).
