Description

[Detailed Description of the Invention] The present invention relates to a partial opening/closing device for a batch cover for closing a cargo batch opened on a deck in an upper part of a ship's hold.

Looking at recent trends in cargo ships, there has been an increase in the number of multi-purpose ships, which can carry a wide range of cargo, from heavy cargo to miscellaneous cargo, so they call at a variety of ports.

Heavy cargo ships often carry large plants in their cargo bays, resulting in long batches, which may be too large to carry miscellaneous cargo.

It is often not necessary to open the entire batch cover if it is limited to a portion of the batch where these small cargoes are loaded.

Furthermore, if there are containers etc. loaded on the batch cover, all of them must be removed to open and close, and this work takes a considerable amount of time at the port of call before the cargo handling work begins.

Conventionally, long batch covers whose front and rear parts are opened and closed separately have been opened and closed using torque hinges, hydraulic cylinders, etc., but such opening/closing devices are expensive to manufacture. .

On the other hand, in order to reduce costs, existing cranes are used to open and close the batch cover.

That is, as shown in FIGS. 1 and 2, the batch cover opening/closing device for long batches is located at the front A and rear B of the batch.
For example, when opening the front A'&, remove the container 02 on the front batch cover 01, and lock the cable 03 at one end of the center of the batch cover [as shown by the two-dot chain line]. The other end of this rope 03 is extended upward via a snatch block 05 attached to the side wall of the deck house 04a, and is connected to a hook paid out from a deck crane to cover the batch by the deck crane. 01 is opened, but when the front batch cover 01 is closed, the cable body 03a that is locked to one end of the front batch cover 01 that is stored upright is closed to the deck house 04b provided at the rear as shown by the dotted line. Snatch block 0 attached to the side wall of
6, the container 0 on the rear batch cover 07
I wonder if 8 will also be removed (・I can't index it (・.

In addition, when opening and closing the rear batch cover 07, it is done in the same manner as the opening and closing procedure of the front batch cover 01 described above, but in short, the containers 02 on the front and rear batch covers 01 and 07
,08 all had to be removed.

In addition, the above-mentioned cable body 03a is attached to the front and rear batch covers 01 and 07.
Since the batch is open when going to attach it to one end of the central part of the hatch, there is a danger in the attachment work because the distance between the end of the hatch coaming 09 and the front and rear hatch covers 0107 is not small.

The present invention proposes a hatch cover partial opening/closing device that can solve the above problems.
This will be explained based on FIGS.

A plurality of long hatches 1 are opened on the upper deck of a multi-purpose cargo ship, and a hatch coaming 2 is provided around the long hatches 10.

On the long hatch 1, there are provided hatch covers 3 and 4 which are divided into two parts in the front and back direction and can be opened and closed.

The front hatch cover 3 and the rear hatch cover 4 also have a plurality of panels 6 each having a rotating wheel 5 and a moving wheel 30 attached to the intermediate sides, and each of the adjacent panels 6 has wheels 5 attached to the intermediate sides. A rotating axle 5 that supports
They are connected by a chino 5b attached to a.

7 is the deck house installed at the bottom of the deck crane.
Front and rear hatch covers 3,
A lead sheep 8 is attached to engage the rope body 94 used when the cable 4 is opened.

Further, a lead block 10 and a connecting metal fitting 11 are provided on both sides of the hatch coaming 2 at the middle portion where the front and rear hatch covers 3 and 40 are divided.

The structure of the lead block 10 and the connecting hardware 11 will be explained in detail with reference to FIGS. 5 and 6. The connecting hardware 11 includes a plate-shaped arm 12 that faces each other, and a support plate 13 inserted into the lower part of the arm 12. , a bracket 14 provided on the side of the arm 12, and this bracket 1
4 is in contact with the center stopper 16.

Furthermore, a piece 15 is attached to the center stopper 16 to forcefully lock the bracket 4 in the left and right directions on both sides.

The arm 12 and support plate 13 are connected by bolts and nuts 17.
A stopper pin 18 is inserted into the intermediate portion of the arm 12, and the arm 12 is fixed in an upright state during use.

Moreover, the IJ-do block 10 is attached to the upper part of the connection hardware 11.

This lead block 10 consists of a pulley 21 mounted in a support frame 19 via a pin 20, and two opposing bifurcated brackets 22 connected to the lower part of the support frame 19. This can be done by removing bolts and nuts 29.

Further, a connecting piece 23 is inserted between the brackets 22, and the lower end of this connecting piece 23 is connected to the upper part of the connecting metal fitting 11 with a bolt nut 24.

Next, when opening only the rear hatch cover 4 with containers 25 etc. loaded on the front hatch cover 3, remove the containers etc. on the rear hatch cover 4 as shown in Figures 3 and 4, and then open the hatch cover. 4. Lock the cable 9 to the snatch block attached to the center of the panel 6 at one end, as shown by the dotted line, and attach the lead 7 to the cable 8 attached to the side of the deck house 7 at the other end of the cable 9. When the rope 9 is hoisted up by the deck crane after being engaged with a hook paid out from the deck crane, the rope 9 is opened by the movement of the wheels 30 on both sides of each panel 6 of the rear hatch cover 4.

Further, each panel stands up as the wheels 5 on both sides roll along the slope of the rampway 26 provided at the end of the hatch coaming 2, and the rear hatch cover 4 is retracted.

When closing the rear hatch cover 4, one end of the cable 27 is locked to the side axle 5a of the end panel 6 of the hatch cover, and the other end of the cable 27 is attached to the front and rear of the hatch cover. The panel 6 is connected through each lead block 10.
It is locked to an axle 5a that supports a wheel 5 provided at a position opposite to the axle 5a.

Further, the cable 2 stretched between the lead blocks 10 and 10
By inserting a handling block 28 into the rear hatch cover 7 and lifting the handling block 28 with a deck crane, the rear hatch cover 4 can be closed while each panel 6 operates in the opposite manner to when it is opened.

After the cargo handling work is completed, the lead block 10 used when closing the rear hatch cover 4 is removed by removing the bolts and nuts 24 from the pulley 21 at the top as shown in FIG. 6, and removing the connecting hardware 11 from the bottom by pulling out the stopper pin 18. , it can be rotated downward and stored between the frames of the hatch combing 2.

Note that the cable 27, lead block 10, and handling block 28 of the rear hatch cover 4 can also be used when the front hatch cover 3 is closed.

According to the present invention described in the above embodiments, one end of the cable is locked to a rotating axle attached to one side of the hatch cover, and the other end of the cable is attached to both sides of the hatch coaming at the center of the hatch cover, which is divided into the front and rear parts. By connecting the hatch cover to the other rotary axle via each lead block provided in the lead blocks, a handling block is inserted into the cable stretched between the lead blocks, and the handling block is lifted by a deck crane. In the front and rear hatch covers installed on long hatches of multi-purpose cargo ships, the rear hatch cover can be opened and closed even when containers, etc. are loaded on the front hatch cover, eliminating the need to remove all cargo on the hatch cover as in the past. , the time required for opening and closing the hatch cover, which is the work before cargo handling at the port of call, can be significantly shortened.

Furthermore, when the hatch cover is closed, there is no need to go through the trouble of attaching cables to the center, allowing for safer work.
