DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulk carrier having a loading facility and a discharging facility, and more particularly to a bulk carrier in which a part of the discharging facility is used for loading.

[0002]

2. Description of the Related Art Amorphous solid cargoes composed of ores, coals, limestones, wood chips, grains, cement, and other small lumps, granules, and powders, ie, bulk carriers for transporting bulk materials by sea, are mainly used in bulk carriers. Those navigating along coastal areas often have to carry out cargo handling work at piers with incomplete harbor handling equipment.

[0003] For this purpose, a bulk carrier is provided with a cargo handling facility, and there is an unloading facility described in, for example, Japanese Utility Model Laid-Open No. 2-33196. This is a dispensing machine that reciprocates in the longitudinal direction of the hull along the bottom of a hopper-shaped cargo hold that is long in the longitudinal direction of the hull in the hold and discharges loose bulk in the cargo hold gradually, and a longitudinal direction of the hull. A first conveyor for extending the discharged bulk material along the bottom of the ship to the bow or stern side of the hold, and a second conveyor for extending the bulk material upward and above the upper deck; It is equipped with a third conveyor that discharges bulk materials at predetermined locations on the pier,
The third conveyor is mounted on a boom that is pivotally mounted on the upper deck.

On the other hand, there is a loading facility described in, for example, JP-A-11-227682. This shuttle is located above a cargo hold that is long in the longitudinal direction of the hull and reciprocates longitudinally on the center line.
The shuttle conveyor is provided with a hopper for supplying bulk material to the shuttle conveyor, and the bulk material supplied to the hopper from the wharf is distributed to the cargo hold by the shuttle conveyor. The bulk carrier described in Japanese Patent Application Laid-Open No. H11-227682 is disclosed in
It is equipped with a discharge facility similar to that described in US Pat.

[0005]

In the case of bulk carriers not equipped with the above-mentioned loading equipment, the bulk can be transferred from a quay to a cargo hold from a hatch using a conveyor such as a conveyor or a bucket. Loading is done,
At this time, the transporter is moved in the longitudinal direction of the hull on the wharf to load evenly so that the hull does not become unstable. In a bulk carrier equipped with the above-mentioned loading equipment, bulk materials are supplied from a pier to a hopper mounted on a hull using a carrier, and the bulk materials are uniformly loaded and loaded into a cargo hold by a shuttle conveyor.

Accordingly, in the latter case, there is no need to move the transporter in the longitudinal direction of the hull, so that the cargo handling equipment on the pier side can be simplified as compared with the former case.

However, in any case, the wharf-side cargo handling equipment is provided with a portion that extends from the land side to the sea side and is evacuated to the land side, and it is not possible to install the cargo handling equipment having such a part on the wharf. In addition to problems in safety, there are problems such as troublesome maintenance management, the need for a driver and an administrator, and a large burden of costs for installation and maintenance. For this reason, there is a tendency to dislike to install a cargo handling facility having a portion projecting from the land side to the sea side at the bulk loading wharf.

SUMMARY OF THE INVENTION The present invention has been made in order to cope with such a situation, and there is provided a bulk carrier which does not need to install a cargo handling facility having a portion projecting from a land side to a sea side on a pier. The purpose is to provide.

[0009]

SUMMARY OF THE INVENTION According to the present invention, there is provided a take-out means for sequentially pulling bulk materials downward from the bottom of a hopper-shaped cargo hold long in the longitudinal direction of the hull provided in the hold, and extending and discharging in the longitudinal direction of the hull.

In addition, there is provided a third transport means for unloading bulk material from the wharf, and the third transport means is provided with a bulk carrier equipped with a cargo handling facility which is installed on a boom rotatably mounted on the upper deck. The above problem has been solved by the following method.

That is, a loading boom rotatably mounted on an upper deck, and a loading transport mounted on the loading boom for transporting loose objects from a distal end portion to a base end portion which is a turning center side. Means and a relay conveyance means for guiding the conveyed bulk material above the entrance of the second conveyance means are added to the cargo handling equipment. Then, assuming that the boom is composed of a fixed length portion on the turning center side and a variable length portion protruding in a region in front of the boom, the bulk transport section length of the third transport means is made variable following the movement of the variable length portion. . Further, a discharging means is provided for discharging the bulk material transported by the third transport means in the middle of the fixed length portion, so that the discharging means can be moved along the third transport means, and the bulk material is laterally moved. It has a scraper that can be evacuated from the discharging position to a position where it does not come into contact with loose objects.

The loading boom is pivoted to protrude above the pier and the variable length portion of the boom is advanced to the maximum position above the cargo hold. The loading / transporting means receives the bulk goods at the wharf and sends them to the relay carrying means. The bulk materials are then fed into the cargo hold from the tip of the variable length portion via the second carrying means and the third carrying means. When the bulk material makes a pile with a predetermined height, the variable length part is retracted to make a pile with a predetermined height at an adjacent location. Load bulk in approximately half the area. After the variable-length portion has been retracted to the maximum, the discharging means means that the bulk material is discharged in the middle of the bulk transport section of the third transport means, that is, the bulk material is discharged at the fixed length portion of the boom, loaded into the cargo hold, and loaded into the remaining area, This is performed by sequentially moving the discharging means toward the center of rotation, or by repeatedly reciprocating.

[0012] The bulk material in the cargo hold is taken out downward by the take-out means, and is landed on the wharf by the first transfer means, the second transfer means, and the third transfer means.

As described above, the boom for unloading and the bulk transport section of the third transport means are variable in length, and the loading boom, the loading transport means and the relay transport means are provided, so that the sea side is provided. Loading and unloading can be carried out by ship-side equipment on a wharf without cargo handling equipment with overhanging parts. Further, since a part of the transporting means is used for both loading and unloading, the entire cargo handling equipment is simplified.

The boom is positioned at the center of rotation on the center line of the hull in front of or behind the cargo hold,
A chute for guiding the bulk material discharged at the end of the transport section of the third transport means is provided at the distal end of the variable-length portion, and the variable-length portion is made to reach near the opposite end of the cargo hold during maximum forward movement. This is a preferable mode for achieving both the uniform loading of bulk materials in the cargo hold and the conventional landing.

[0015] Further, with respect to the loading boom, the turning center is placed beside the turning center of the boom so that the loading boom can turn between a standby position placed on the upper deck and a receiving position protruding from the side of the ship. It is preferable that a hopper for receiving bulk materials is provided at the tip end in that the bulk material received on the land side is transported to the entrance of the second transport means at the shortest distance. Furthermore, in addition to enabling the loading boom to be turned, it is possible to ascend and descend in a preferable form in that it can receive loose objects without trouble even if the height difference between the upper deck and the pier changes. is there.

The boom comprises a main frame forming a fixed length portion and a sub-frame movable in the front-rear direction along the main frame and forming a variable length portion, and the main frame includes a discharging means. It is preferred that
