Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for opening and storing a hold opening f for forming a multi-tiered hold by partitioning the hold of a cargo ship or the like in the depth direction, and particularly for a container ship. It has a long warehouse mouth such as
In addition, even if the cargo ship does not have a sufficient deck opening, the removed hold mouth can be properly stored within the hull, and the bow can be formed with multiple V holes to accommodate a variety of cargo. 6. This invention relates to a method for opening and storing a cargo hold lid, which can be used for a variety of purposes on a cargo ship such as a container ship.

Many of the cargo ships built in recent years tend to be specialized vessels for carrying specific cargoes, such as tankers for crude oil and LNG carriers for natural gas. It is becoming common to store and transport cargo in standard containers, and many container ships are being built. These container ships carry and store relatively large containers in their holds, so compared to conventional cargo ships, they have larger holds and longer hatch openings. It is a characteristic. However,
Dedicated vessels such as container ships are only equipped with facilities that give priority to containers, so sometimes cargo cannot be balanced and one space is left over in the hold. Operating under such conditions would result in damage, so it is requested that the vessel be equipped with additional equipment to allow it to carry some kind of cargo (such as copycat cargo). As a solution to the above, it is conceivable to give priority to the cargo hold that accommodates the containers and make it thicker, and then install a tray such as a second deck above the cargo hold to form a separate multi-stage V cargo hold.

Conventionally, the second instep 'r11 had a hatch of a common caliber.
．． The method shown in Figures 1 and 2 is known as a method for opening and retracting the bow mouth of a cargo ship that is moving forward. Monodome 9.

・Since it is constructed in the shape of a pot/saw 7 and has a predetermined thickness in order to hold a predetermined metallurgy, it cannot be stored beyond the height t of the storage space n. Attempting to lower the height at which the boxes can be stacked increases the length of each piece, causing problems such as the storage racks protruding toward the warehouse entrance and complicating cargo handling operations. There was.

The present invention was founded in view of the above-mentioned problems, and its purpose is to solve problems such as those of container ships, etc., which have a long hatch, and have a high height between the decks, for example, between the upper deck and the second deck. Even if a cargo ship does not have enough trays, it can be properly stored in the hull above the cargo hold mouth, which is removed to open the cargo port, and the cargo hold can be formed into multiple tiers to accommodate a wide variety of cargo. An object of the present invention is to provide a complete method for opening and storing a cargo hold opening, which allows a cargo ship such as a container ship to be used for multiple purposes.

Below, preferred methods for opening and storing the cargo hold roof according to the present invention are as follows.
A practical example will be described in detail with reference to the accompanying drawings showing an example of a container ship having a large-capacity hold and a long hatch.

Container ship hull 1 shown in Figures 3 and 5 P
has a double-hull structure, and the hold 2 has an inner shell 1a and
~ horizontal partition walls 3 appropriately arranged in the longitudinal direction. The upper deck 4 that partitions the upper part of the hold 2 has a long hatch 5 for use in cargo handling operations, and a 2N bottom top plate 6 is attached to the bottom. rBJVr- of the 2N bottom filling plate 6 and the upper deck 4, a second deck 7 is provided in parallel thereto. This second deck 7 includes an upper deck 4
An elongated second deck hatch 8 that substantially coincides with the hatch 5 is formed. In addition, this second deck 1 is provided close to the upper deck 4 in order to form a lower cargo hold (hereinafter referred to as "container hold J") 2a't-large capacity, and is relatively narrow. A hold section (hereinafter referred to as "Kokei-makura") 2bvi'' is formed between the decks for storing cargo other than containers.
VC is provided with a hold mouth 9 for closing it and dividing it into sections in the depth direction of the hold 2t''.This hold mouth 9 is divided into a plurality of pieces along its longitudinal direction to form divided holds. The palate 1o... is formed in a rigid pontoon shape that supports cargo M turtles.These divided hatch 1o...
As shown in Figures 3 and 4, ... is the second deck warehouse entrance 8.
The hook is passed over support beams 11 extending from the peripheral edge of the frame, and is supported in a detachable manner. (Hereinafter, in this embodiment, these divided Kuraguchi M1o... will be referred to as "Panel A", "Panel B", etc. from left to right in the figure for convenience) , named ``) Gunel M''. ) As shown in FIGS. 5 S and TK, the split hatch cover 10 constructed in this manner includes the split hatch cover 10 at the end adjacent to the second deck 7VC, that is, panel A and panel M.
are the hatch beams 12 of the second deck plank and the upper deck hatch 5, respectively.
・It is divided into lengths lower than the height between them in order to be stored between them, and is pivotally supported to the hull 1 side at the edge of the second deck 1 so as to be freely deployable. Furthermore, in these panels A and M, there are other divided hatch lids 10 located on the center side.
For example, Tsukuneru E1 panel F etc. are placed and tied up,
It is constructed so that as many divided hatch covers 1υ as possible are stored between the decks. Then, these panels A and... and Nell MIC are expanded and moved to Kimiguchi 12.
A storage means 13 is provided which stands up along the ... and stores the entire structure including the ..., the flannel E, etc. between the decks. This storage means 13 is comprised of a wire loaf 14 connected to each of the four channel A and panel M, and a winch (not shown) provided on the ship to completely wind the wire loaf 14 and the like.

On the other hand, the IP panel A and the panel M, which are the end portions of the roof,
And, at least one of the split hatch lids 10 other than ``Ya Nell E'', ``Gun Nell 2'', etc., which are deployed together with the mounting type, has a VC loaded into the container hold a first, and its A traveling means 1 such as wheels driven by an electric motor runs on a double bottom top plate 6 serving as a bottom plate and is moved to the hull 1 side below the second deck T.
5 is provided. In this embodiment, a panel DVc adjacent to panel E is shown. This panel DiC includes a split hatch lid 10 other than the above, for example, panel G.
It is configured such that panels C etc. are stacked one after another. The transport of these panels G and the like and the panel E and the like is configured to be carried out using a loading means 16 such as a crane provided as land equipment or shipboard equipment.

Next, as shown in Figure 5P, when cargo other than containers is stowed between decks t2b, the opening and closing route network method of the ship's roof is directly cut. In order to close the ship's bow mouth 9, the divided hatch covers 1tl... are arranged in a row on a support beam 11. When the second deck hatch 8 is opened and the bow mouth 9 is completely stowed, the following procedure is carried out while carrying out the containers 11 loaded with the container bow 2aVc.

First, as shown in FIG.
With the adjacent iR channel E and nozzle E, the 2nd deck cargo hatch 8 is opened tightly, and the 2nd deck cargo door 8 is transferred to the tunnel A and the tunnel M 9111K by the loading means 16, respectively, and these tunnels are removed. Stack and place on top. At this time, bind these panels together and make them look like one piece.

Then, the containers 1γ... are carried out from the second deck hatch 8, which is partially opened due to the removal of the panels E1 and F, and are transferred to land.

Next, as shown in FIG. 5 RVc, the container M-2a formed by carrying out the containers 11...
, the nogunnel D equipped with the traveling means 15 is carried in from the opened second deck hatch 8 by the loading means 16 and positioned on the double bottom top plate 6.

Thereafter, as shown in FIG. 5S, panels G and C are sequentially opened from the warehouse opening 8 opened by the loading means 16.

J, B and [t are carried into container hold a and stacked on panel D. At this time, the second deck hatch 8 is sequentially expanded, so that all the containers 17 can be transported to land as appropriate. At this time, or in advance, the panel A and the wire rope 14 of the Norel MK storage means 13 may be connected.

Thereafter, as shown in Figure 5T, the 10th storage stage 131/C, along with panels E and F, were expanded and moved to stand up on the deck and between the panels A and M, respectively. .

Then, the container 17 attached to the corner of the container foot 2a is carried out from the long second deck entrance 8 which is opened properly and substantially coincides with the underground JIT entrance 5. Finally, in order to place it under the 4th and 1st deck of the 2nd deck of hold 2, which was now empty, we made a multi-stage gunnel. Transport the finished panel Dk. In this way, as shown in FIGS. 5T and 6, the entire end portion 1iC of the bow 2 and the hold mouth 9 are retracted.

On the other hand, when loading cargo, especially containers 11...t
When loading the container neck 2a VC and further stowing cargo other than the container on the deck slip 2b, the VC may perform the above procedure in reverse.

In addition, if the entire cargo hold 2 is to be used as a container hold, loading should be carried out with the second deck opening 8 fully open. good.

By the way, in the VC of the present invention, when dividing the hold 21'ik in the depth direction, the hold mouth 9 that opens and closes the hold mouth 8 is partially stored between the decks, and the second deck, which has become raw, is Since it is possible to properly lay out the cargo space in the lower hold, it is effectively adopted for cargo ships such as container ships that have long hatches and cannot have a sufficient height between the decks. obtain.

Therefore, the TLC second deck and other facilities in the hold hold a wide variety of cargo.
J can be rammed, a dedicated cargo ship such as a container ship can be used for multiple purposes as appropriate, and the efficiency of pail transport can be completely increased.

The storage location of the bow mouth according to the present invention is a location where the upper deck 4 extends out to the side of the hold 2, making it relatively difficult to perform cargo handling. This is not a method that reduces space, but rather a method that effectively utilizes the space within the hold to achieve storage of the bow palate 9.

Furthermore, by storing as many split hatch covers 10... as possible on the open deck side, the number of split hatch covers that can be stacked under the deck can be reduced by 8g2, f51 - lj,
It can be effectively used even if there is a 1/C hold that is not deep enough.

Also, the workers who are engaged in hooking the wires of the cargo dumping means 16 to the storage means 13 to the divided hatch lids 10..., can move the divided hatch lids to be transferred one by one without a special passage. 1
0: It is possible to move while continuing work on board and return safely to the ship.

In summary, the VC of the present invention has the following excellent effects. Demonstrate.

(1) The cargo hold opening, which divides and partitions the interior of the cargo space in the depth direction, should be appropriately stored on the cargo side, such as in the corner of the cargo room or in the corner of the cargo hold, where the upper deck extends and is relatively difficult to carry out cargo handling operations. Therefore, VC can be effectively adopted for cargo ships such as container ships that have long hatchbacks and cannot have sufficient height between decks.

(2) Therefore, the inside of the ship's hold can be divided in the depth direction, and a variety of cargo can be loaded onto a dedicated cargo ship such as a container ship.
It can be used for multiple purposes, and its transport efficiency can be improved.

(3) Since the structure is such that the split hatch lids are stored on the deck 1''EAj side, the number of split hatch covers transported on the bottom plate can be reduced by 1iJ, and the depth force can be reduced. It can be effectively used even if there are six VCs in the hold that cannot hold enough balls.

(4) The structure is simple and can be easily adopted.
