Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cargo/vehicle carrier that can be used as a dedicated carrier for cargo such as automobiles or containers, or as a mixed carrier for automobiles and cargo.

Regarding the loading method of the hull, the roll-on roll-off (self-propelled boarding and disembarkation) method for car carriers is replaced by the lift-on and roll-off method.
The purpose of this is to improve the loading efficiency of the lift-off method, and the cell guide method on container carriers is used to improve the loading efficiency of the lashing method.

Since car carriers and container carriers each have their own loading methods, the hulls themselves are designed and constructed accordingly.

For this reason, it has conventionally been impossible to load cargo such as containers onto a carrier exclusively for automobiles, or conversely to load automobiles onto a carrier exclusively for containers.

Due to these circumstances, all of the above-mentioned dedicated carriers have been forced to reduce transport efficiency due to one-way cargo.

The purpose of the present invention is to solve such problems, and in a carrier ship having multiple decks, the deck is divided into a fixed deck on the side part and a movable deck in the central part below the hatch opening, and The movable deck is configured to be movable onto the fixed deck by running on fixed beams disposed at intervals at which containers are inserted, and the fixed beam is provided with a plurality of cell guides for stacking containers in multiple layers, and these cell guides A part of the cell guide is of a fixed type and the rest is of a swing type so that the swing type cell guide can be interlocked with the movable deck, and when the movable deck is in the central part, the swing type cell guide This objective is achieved by providing a cargo/vehicle carrier configured such that the movable deck is in a horizontal storage position along a fixed beam and the swinging cell guide is in an upright position when the movable deck is on the side fixed deck. As a result,
It can carry cars and/or cargo.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be explained in detail below based on the drawings showing one embodiment thereof.

This example is intended to adopt the roll-on/roll-off loading method when carrying automobiles, so it is possible to use a car-only carrier that is equipped with an existing rampway for this purpose, and is capable of carrying both cargo and cars only. Or it has been modified to be able to carry only cargo.

1 to 4, the interior of a carrier 1 according to the present invention is partitioned in the bow and stern direction by bulkheads 2, and each partition is provided with a plurality of decks 3 at intervals that allow containers to be inserted. It is provided via a grid-like beam frame 4.

5 is a batch opening, 11 is an upper deck, a rampway 12 is formed on the upper deck 11, and a passage 13 is formed on the bulkhead 2, so that the automobile X can be rolled onto any deck 3.
It is configured to roll off.

Note that Y is a container.

5 to 7 show an enlarged cross section and an enlarged plan view of the port side of the carrier 1.

As is clear from the figure, the deck 3 is divided into a side part and a center part below the batch opening 5, and the center deck is further divided into two parts along the hull centerline, each of which is separated from the nearest part of the side deck (fixed deck) 6. It has a movable deck T that can slide upwards and horizontally.

In addition, FIG. 5 shows a state where the movable deck 7 is moved to the center of the hull, and FIG. 6 shows a state where the movable deck 7 is moved to the side of the ship.

This slide mechanism will be described later.

The lower part of the batch opening 5 in the beam frame 4 has two longitudinal beams 4A arranged at equal intervals on the hull centerline and on the left and right sides of the centerline, of which one on the hull centerline and the outermost one. Fixed struts 8 are provided at the intersections with the transverse beams 4B, and these fixed struts 8 connect and reinforce the beam frames 4 to fixed decks 6 of adjacent stages.

A container cell guide (fixed cell guide) 9 is fixed to each of the fixed columns 8.

The lower ends of these fixed cell guides 9 are cut off to allow the sliding of the movable deck T, and the containers (not shown) passing through the cutout portion 9A of the upper fixed cell guide 9 can be smoothly moved through the fixed cell guides. In order to accommodate the receiver 9, its upper end is constructed in a twisted shape.

Reference numeral 14 is a flip-up inclined plate provided between the movable deck 7 and the fixed deck 6, and serves to smoothly perform roll-on and roll-off.

In addition, in FIG. 6, 17 is a cable body, 18 is a sheave, and 19 is a winch installed on the upper deck 11, and these are for sliding the movable deck I as described later.

FIGS. 8 to 10 show enlarged portion A of FIG. 5.

In the figure, reference numeral 10 denotes a swinging cell guide (swinging cell guide), and the cell guide 10 is interlocked with the movable deck 7.

That is, when the movable deck I is located at the center below the batch opening 5, the swinging cell guide 10 is retracted along the horizontal beam 4B (see Figure 10), and when the movable deck 7 is completely moved onto the fixed deck 8. When slid, the swinging cell guide 10 stands up in the center between the fixed cell guides 9 adjacent in the ship width direction (see FIG. 8).

FIG. 9 shows the intermediate state. FIGS. 11 to 13 show a plane view of the swinging cell guide 10 when it is in the retracted state and an upright state, and a side view when it is in the upright state.

As is clear from the figure, two sets are provided corresponding to the front and rear ends of the movable deck T of the swing cell guide 10, and one set and the other set of each set correspond to the fixed cells. Together with the guide 9, they form a set of four to guide a container (not shown).

The interlocking mechanism between the swinging cell guide 10 and the movable deck 7 will be described later.

FIG. 14 (Based on the enlarged opening of FIG. 13 and FIG. 6, the sliding mechanism of the movable deck 7 will now be described.

The movable deck 7 has a plurality of rollers 16 at its front and rear ends, and as shown in FIG.
It is possible to run on it.

At the left and right ends of the movable deck γ, there are cables (
(chain, wire rope, etc.) 17 are connected,
This cable 1T is guided along the transverse beam 4B to the ship's side,
This is roughly connected via a sheave 18 to a winch 19 installed on the upper deck 11.

Therefore, by rotating the winch 19 forward and backward, the movable deck 7 can be slid between the central portion below the batch opening 5 and the fixed deck 8 on the side.

Positioning on the movable deck 7 and in the central portion is performed by dropping the roller 16 into a recess (not shown) formed in the transverse beam 4B.

Next, regarding the interlocking mechanism between the movable deck 7 and the swinging cell guide 10, the operation diagrams shown in FIGS. 8 to 10 and FIGS.
This will be explained based on FIG. 14.

The upper ends of the pair of swinging cell guides 10 are attached to the horizontal beam 4B via pins 20 at mutually adjacent positions, so that the pair of swinging cell guides 10 can freely swing in opposite directions around the pins 20. It becomes.

The base end of a ring 21 of equal length is pivotally supported in the longitudinal center of each swinging cell guide 10, and the link 21
The tips of the two are connected to each other by a pin 22.

A base end portion of an arm 23 is connected to this pin 22 .

A horizontal engagement rod 24 is fixed to the tip of this arm 23 (particularly evident in FIG. 14).

On the other hand, metal fittings 25 that can be engaged with and detached from the engagement rod 24 are fixed at appropriate positions on the front and rear end surfaces of the adjacent movable decks T so as to face each other.

As shown in FIGS. 15 and 16, this metal fitting 25 has a notched hole 26 that is long in the sliding direction of the movable deck 7, and one side of the cutout hole 26 is slightly larger than the diameter of the engaging rod 24. A through hole 26A is formed, and a bulge 26B is integrally formed at the upper part behind the ventilation part 26A.

When the movable deck 7 slides from above the fixed deck 6 toward the center below the hatch opening 5 in the order shown in FIGS. The receiver is inserted into the notch hole 26 from the opening.

Therefore, when the movable deck 7 is further slid after the engagement rod 24 is received in the notch hole 26, the engagement rod 24 is pushed by the back wall 26a of the notch hole 26, and as the movable deck 7 slides, the arm 23 is pulled.

Therefore, the pin 22 rises in the vertical direction from the relationship in which the pair of swinging cell guides 10 are attached to the transverse beam 4B by the pin 20.

Following the rise of the pin 22, the swinging cell guide 10 is pushed up in opposite directions by the equal length link 21 and swings upward (see Fig. 9), and simultaneously when the movable deck 7 is slid to a predetermined position. It is stored in a horizontal position on the side of the horizontal beam 4B (see Fig. 10).

Conversely, when the movable deck 7 is slid from the central portion toward the fixed deck 8, that is, when the movable deck 7 is slid in the order shown in FIGS. is pushed downward.

For this reason, the engagement rod 24 is pushed upward via the arm 23, so that the engagement rod 24 is pushed up against the bulge upper wall 26 of the notch hole 26.
b or engages with the step wall 26C between the swollen portion 26B and the through hole 26A (see FIG. 16).

Therefore, the swinging cell guide 10 slowly swings downward, overtaking the slide of the movable deck 7.

When the swinging cell guide 10 assumes the standing position, the arm 23 also assumes the standing position;
Since the weight of the swinging cell guide 10 no longer acts on the locking member 10, the engaging rod 24 faces the through hole 26A.

Therefore, when the movable deck 7 is further slid thereafter, the engagement rod 24 passes through the through hole 26A, is relatively removed from the notch hole 26, and is separated from the metal fitting 25.

After that, the movable deck 7 slides onto the fixed deck 8,
Positioned.

In order to perform the above operation smoothly, as shown in FIGS. 17 and 9, a stopper fitting 2 is attached to the horizontal beam 4B.
7 is provided so that the arm 23 can be reliably maintained in its upright position.

Next, the overall operation of such a configuration will be explained.

First, when only the automobile X is to be loaded, the movable deck 7 is positioned at the center below the hatch opening 5, the inclined plate 14 is set, and the automobile X is sequentially rolled onto any deck 3.

In addition, when loading only container Y, first load container Y onto the uppermost movable deck T from the same state as when rolling on automobile Container Y is loaded onto the movable deck 7 of the tier.

After repeating this operation one after another, slide all the movable decks 7 onto the fixed deck 6, and then move the container into the hold formed below the hatch opening 5 using the fixed cell guide 9 and the swinging cell guide 10. Stack Y in multiple layers as shown in Figure 3.

In this case, the containers Y can be stacked on the hatch cover 15 and the upper deck 11 in the same manner as before.

Next, when you want to fight car X and container Y, first roll on car X onto movable deck γ in the same state as when only car X is rolled on, and then
After sliding the containers Y onto the fixed deck 6, the containers Y are stacked in multiple layers as shown in FIG. 4 in the same manner as described above into the hold formed below the hatch opening 5.

In this way, problems caused by one-way cargo can be solved and transportation efficiency can be improved.

As described above, according to the present invention, it is possible to load only a car, only cargo, or even a car and cargo at the same time, so that the problem of one-way cargo, which has conventionally been a problem in terms of transportation efficiency, can be solved.

In addition, some of the multiple cell guides for container multi-layer stacking provided on the fixed beam are fixed, and the rest are swingable, so that the swingable cell guides can be linked to the movable deck. The cell guide, which is an obstacle when rolling on and off the ship, can be stored along the fixed beam, making it fully suitable for use as a car carrier.
