Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for continuously unloading cargo from a bulk cargo carrier or collecting it on land. Loading or unloading for continuous loading of cargo scheduled for transfer 1. It is related to the device.

BACKGROUND ART Conventionally, agricultural products such as grains, mining raw materials such as ore, and granular or powdered raw materials used in various chemical industries are transported by sea using bulk loading.

When loading a ship using this transportation method, for example, belt conveyors, cranes, fluid transport equipment, etc. are used, and when unloading at a port of call, cargo is unloaded according to the unloading equipment of the facilities installed at each port of call. .

However, in general, when loading a ship, equipment suitable for the cargo is used, but at a port of call, suitable equipment is not necessarily used. Later, when loading another bulk cargo, it may be necessary to move the loading device to a certain location.

Recently, this trend has been further exacerbated by the necessity of adopting a different mode of transportation with the intention of improving transportation efficiency on ships.

Specifically, a very good example would be transporting grain from an agricultural country and returning from the destination with a load of mining products (such as iron ore).

In such cases, it is clear that efficiency will be improved if unloading and loading operations can be performed using the same device.

The present invention provides for the loading or unloading of bulk cargo at at least one location around the offshore dolphin where the bulk cargo approaches the shore and unloads and straddles the cargo. Extension to contact 1. a traversing conveyor device, 17 at the end of which the bucket conveyor operates in conjunction with the traversing conveyor device, 2 at least two hoppers near the top of the bucket conveyor; Loading or unloading on a ship 1, characterized in that a crane device is included for discharging cargo into one hopper, and is connected to a conveyor device for loading cargo from another hopper.
．． 1-2 relates to a relatively compact yet highly efficient cargo unloading device for a carrier ship.

The present invention will be described in detail below based on the drawings.

FIG. 1 is a schematic diagram showing the entire main apparatus of the present invention. First, a loading line 6 is formed by combining a unloading line 3 consisting of a crane 1 and a hopper 2, a hopper 4, and a telescopic chute 5. are provided on the Dolphin 7. The dolphin 7 has a depth that allows bulk cargo to come ashore at sea, and is equipped with a conveyor device 8 such as a bucket conveyor that can transport the cargo up and down between the foundation and the seabed.

[2] A traversing conveyor device 9 is provided at the foundation within the dolphin 7 or on the seabed 10 until it reaches a predetermined loading yard on land.

Tunnel 11 inside Dolphin 7 and the traversing conveyor device
The section is naturally formed of dolphin and l.) flannel which keep the surrounding area watertight.

Considering recent trends in large-scale transportation, Dolphin 7 will be able to maintain a depth of about 7 m from the seabed to sea level 1, and it is possible that about 50 m will be needed from the broken sea surface to the top of crane 1. If the effective working length of the crane 1 is also about 37 m, it is possible to handle a 60,000-class Norku transport ship, for example.

At this level of scale, the maximum size is 1,20
o+1. + degree of unloading becomes possible.

On the other hand, this device also loads cargo, and its configuration will be explained next using FIG. 1.

To be adapted to this purpose, the dolphin 7 is provided with a separate hopper 4 below the upper end of the vertical conveyor device 8. A transverse conveyor I7, such as a small-scale belt conveyor, is arranged at the bottom of this hosono (4), and the cargo transferred by this conveyor is loaded onto the target bulk cargo by a telescoping chute 5.

The functions of each device will be explained below using the case of unloading as an example.

When unloading the cargo from the cargo ship 12 moored on the Dolphin for unloading, the crane 1 moves the bulk cargo 1
The grab bucket 13 hangs down from the crane 1 that moves to the target No. 2, positions its tip, and fixes it.The grab bucket 13 grabs the cargo inside the ship and pulls it out.
is moved to above the hopper 2 by the traverse means of the crane 1, and discharges the cargo into the hopper 2 here.

The cargo placed in the hopper 2 is fed into a supply hopper 15 of a conveyor device 8 that moves up and down by a feeder 14 arranged at the bottom of the hopper 2, and from there is fed to a supply hopper 15 of a conveyor device 8, such as a bucket conveyor, to the bottom of the dolphin 7. The cargo transferred in this way is sequentially transferred to the horizontal conveyor W.
The tunnel is supplied with 9 VC and transported within the tunnel in the size of a land accumulation yard.

Now, the shipping or unloading device according to the present invention is such that the main parts of the device can be used for both purposes, and when carrying out shipping, for example, a vertically moving conveyor device 8 and a traversing conveyor device are used. 9 can be reversed. Also, the terminal end of the traversing conveyor device 9 is set at 1 to 1 so that the angle can be changed separately with respect to the hopper 18Vc provided at the lower end of the conveyor device 8. It is also possible to make them correspond.

It goes without saying that Dolphin 7's structure would be destroyed even if various equipment such as crane 1 were placed on top of it, but it is necessary to have a wall thickness of about 5 m, for example. If it is a concrete structure, it will be able to withstand the various equipment for carrying out the above-mentioned 1200- treatment.
