Abstract

PURPOSE:To aim at making the working of unloading efficient, by reciprocating a scraper along an inclined path which is inclined upward from the bottom surface of a cargo hold of top opening type arranged longitudinally of a ship, in order to rake up the bulk cargo in the hold. CONSTITUTION:In the end section of a top opening type bulk cargo hold 1 for storing therein dredged mud or the like, which is laid longitudinally of a ship, a curved surface 1b is formed curved and inclined upward from the bottom surface 1a of the hold 1. An outboard discharge device including a hopper 13 and a belt conveyor 14 is connected to the opening of an inclined member 4 which is provided on a top deck 2 so that it is connected to the hold curved surface 1b through a support bed 3. The unloading of the bulk cargo in the hold 1 may be efficinetly made by a scraper 5 which is adapted to reciprocate along the curved surface 1b in the hold 1 and the inclined member 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carrier for carrying bulk cargo such as dredged soil, and particularly to a carrier for unloading bulk cargo.

Conventionally, when unloading dredged soil onto land from a carrier equipped with an upper-barrel type para cargo hold, the carrier was berthed and then unloaded using a grab bucket from inside the mud hold. .

1- However, after unloading using such grab buckets, only small grab buckets that can be inserted into the narrow cargo hold can be used, which requires long hours of cargo handling work, leading to a reduction in the operating rate of the carrier ship. There is.

The present invention attempts to solve these problems, and aims to provide a bulk cargo carrier that can efficiently and quickly unload bulk cargo such as dredged soil.

For this reason, the bulk cargo carrier of the present invention is equipped with an upper-to-bottom round-shaped bulk cargo hold arranged in the direction of the ship's ship, and in order to unload the bulk cargo in the hold, a reciprocating movement is made between both ends of the cargo hold. a scraper that can be scraped up, a ramp that ascends and slopes from the bottom of the hold at the end of the hold, and a cargo handling member for overboard discharge that receives the bulk cargo scraped up by the scraper along the ramp. It is characterized by

In this way, by combining the ramp that ascends and slopes from the bottom of the upper-to-bottom type bulk cargo vessel with the scraper that scrapes up the bulk cargo along the ramp, it is possible to Coupled with cargo handling components for overboard discharge that receive bulk cargo,
This has the effect that the process after unloading bulk cargo can be carried out extremely efficiently.

A bulk cargo carrier as an embodiment of the present invention will be explained below with reference to the drawings. Figure 1 is a plan view of the hull,
The figure is a side view of the hull, and FIG. 3 is a cross-sectional view of the hull, with the left half showing a cross section near the stern and the right half showing a cross section near the center of the hull.

As shown in these figures, an upper, round-shaped bulk cargo hold 1 for storing dredged soil, etc. is arranged in the direction of the ship's ship, and the end of the hold 1 is curved and sloped upward from the bottom surface 1a. Curved surface 1
b is formed.

A two-part structure 3 is provided on the first deck 2 of the stern section, and an inclined member 4 is provided which utilizes this structure 3 to connect to the hold curved surface 1b.

In this way, the hold curved surface 1b and the inclined member 4 form a ramp A that ascends and slopes from the bottom surface 1a of the hold 1.

3- There is also a scraper 5 that reciprocates between both ends of the hold 1.
There are i groups of scrapers on the left side, and each scraper 5
is driven by a cable 9a that runs from the return winch 6 at the stern section through a slide 11t7 on the two-part structure 3 and a pulley 8 on the bow section to the scraper 5, and from the scraper 5 to the superstructure 3 section. This is carried out using a cable 9b that passes through a pulley 10 and reaches a raking winch 11 at the stern of the ship.

Therefore, with the winding operation of the cable 9b by the scraping winch 11, the dredged soil scraped out from inside the hold 1 by the scraper 5 is scraped up along the ramp A, and the dredged soil is scraped up into the upper part 4a of the ramp member 4. It is designed to be carried up to

An opening 12 is formed in the upper part 4a of the inclined member, and a hopper 13 is provided below this opening 12 by using the upper structure 3. ing.

Furthermore, a belt conveyor 14 is provided to receive the dredged soil that has fallen through the hopper 13, so that the dredged soil can be sent to the dredged soil receiving means on land-1-4.

With the above-described configuration, the scraping winch 11 is operated to scrape and scrape the dredged soil by the scraper 5 through the opening 12* at the top of the ramp A, and the return winch 6 is operated to scrape and scrape the dredged soil using the scraper 5. The operation of returning the material to the bow end of the hold 1 is repeated, and in this way, the material is transported from the opening 12 through the hopper 13 to the belt conveyor 14.
Dredged soil that has fallen onto the ground can be smoothly unloaded onto land.

In addition, each winch 6.11 is operated by the scraper 5 in the upper structure 3'' second hunt roll box 15.
This is done in conjunction with monitoring the operation of the

In the above embodiment, the dredged soil is scraped out only when the scraper 5 moves toward the stern, but by providing a 180-degree reversal mechanism for the scraper 5, dredged soil is scraped out only when the scraper 5 moves toward the bow. It is also possible to more efficiently unload the dredged soil through the ramp, hopper, belt conveyor, etc. provided at the bow of the ship by scraping out the dredged soil.

Further, instead of the overboard discharge material handling member consisting of the hopper 13 and the belt conveyor 14, an overboard discharge material handling member such as a chute may be provided.

As detailed above, according to the para cargo carrier of the present invention,
It is equipped with an upper square-type bulk cargo hold arranged in the direction of the ship's ship, and includes a scraper that can reciprocate between both ends of the hold in order to unload the bulk cargo in the hold, and an end of the above-mentioned hold. The simple structure includes a ramp that ascends and slopes from the bottom of the hold, and a cargo handling member for discharging overboard that receives the bulk cargo scraped up by the scraper along the ramp. This method has the advantage that dredged soil, etc., can be unloaded efficiently and safely in an extremely short period of time, which previously required the unloading of dredged soil.
