[Detailed description of the invention]

[Industrial applications]

 The present invention relates to an RV-carrier (a transport ship such as a multi-layer deck car for ocean going).

[0002]

[Prior art]

 Overseas multi-layer deck carriers have developed since the 1960s with the development of the Japanese automobile industry and an increase in overseas exports. Until the 1970s, major export destinations were to the United States and Europe, and most of the exported vehicles were small passenger cars. Eventually, as high-quality Japanese automobiles received high praise from around the world, export destinations, export volumes, and types of vehicles expanded dramatically. Against this background, the early multilayered multi-layer deck car carrier was built mainly for the purpose of transporting large amounts of passenger cars, and the height of passenger cars was about 1,500 mm. It is built as an ocean-going multi-layer deck ship with a large deck height of 600 to 1,700 mm (called PCC). Since then, the expansion of export destinations and the types of vehicles have led to a growing need for transportation of light trucks, vans, etc., and the number of multi-layer deck carriers with a large inter-deck height of about 2,100 to 2,200 mm for loading them has increased. I've been. In addition, a number of ships (called PCTCs) with multiple decks capable of adjusting the distance between decks for loading heavy trucks, dump trucks, buses, construction equipment, etc. have been built, It has become mainstream.

In recent years, in recent years, the sales volume of four-wheel drive vehicles, minivans, wagons, and the like, which are called recreational vehicles (sports utility vehicles in the United States), have expanded worldwide, and automakers have become increasingly involved. Competing to develop a new "RV car", and sales volume is also expanding dramatically. Since these RVs have a height of about 1,600 mm to 1,800 mm, they cannot be loaded on a conventional "passenger car deck". Therefore, these are conventionally loaded on the deck on which the aforementioned "light trucks" are loaded, and a solution called "increase in light truck decks" is adopted as a solution to the increase in RV vehicles. .

However, in response to a dramatic increase in the need for loading RV vehicles, the above-mentioned solution of increasing the number of “light truck decks” having a height between decks of 2,100 to 2,200 mm has the following problems. Remains. One is the decrease in the number of vehicles loaded due to the limitation on the number of decks, and the other is the increase in wasted space when loading RVs. In the former, having many of these “light truck decks” would naturally increase the height (depth) of the entire ship, but the higher the height of the ship, the higher the center of gravity of the ship, Significantly degrades the stability performance of Satisfying the stability performance is a basic requirement of a ship, and lacking it is synonymous with no longer satisfying the requirement of a ship. Therefore, increasing the height is naturally limited. An increase in the number of “light truck decks” means a decrease in the total number of decks, and the disadvantage is that the number of vehicles loaded decreases.

In the latter case, the RV vehicle has a vehicle height of 1,600 to 1,800 mm as described above. Therefore, when loaded on a “light truck deck” of 2,100 to 2,200 mm, the difference is large. A disadvantage is that about 500 mm is a wasteful space. In such a ship with multiple decks, the effect of this wasted space is very large.

[0006]

[Problems to be solved by the invention]

 Based on the above concept, based on the basic concept of “maximizing the effective use of space”, the present invention prevents a decrease in the number of loaded vehicles due to the limitation of the number of decks and increases the wasteful space when loading RV vehicles. This is to increase the space available for loading RV vehicles.

[0007]

[Means for Solving the Problems]

 The problem is that the total effective area of the RV-deck and the deck having a clear height of 1,900 mm or more in a transport ship such as a multi-layer deck car for ocean going is one layer or more. The problem is solved by the above-mentioned transport ship such as a multi-layer deck car for ocean going, which is 85% or more of the effective area of the deck.

The most effective distance between decks for enabling a large amount of RVs to be loaded without waste and maximizing the use of space is “a deck exceeding 1,730 mm and less than 1,900 mm”. Based on the conclusion that there is, this is called "RV deck". By holding this RV deck at 85% or more of the effective area of the vehicle deck of the entire ship, the proposition of effectively loading a large number of RV vehicles is solved. Since it is necessary to secure the loading of "small trucks" that have a height higher than that of RV vehicles, it is effective for loading RV vehicles themselves including these "small truck decks". Here, the definition of the distance between decks is called the clear height as a concept, and the depth of the deck, ribs, cross beams, vertical girder, etc. constituting the deck is determined from the design distance of each level between decks. This refers to the excluding distance, and also the actual effective height between decks excluding margins that must be considered in design, such as machining errors and deck flexure.

【Example】

 FIG. 1 is a schematic cross-sectional view of a transport ship such as a multi-layer deck car for ocean going according to the present invention, which is an embodiment having a 12-layer vehicle deck floating on the sea at a draft of 9.3 m. In this example, each deck of well 1, well 2, well 3 and well 12 is an "RV deck". Well 4, well 5, well 7 to well 11 are "small truck decks", and well 6 can accommodate larger vehicles. In this embodiment, there are four levels of "RV decks", and the deck of 1,900 mm or more becomes all the other decks. Therefore, when both are combined, the ship can be loaded with 100% RV. In this embodiment, RV vehicles can be loaded indefinitely without any reduction in the number of loaded trucks, and a higher ratio of "small trucks" can be loaded. Furthermore, three movable adjustable deck wells 5, 7 and 9 are provided so that large trucks, buses, construction equipment and the like can be loaded.

As a specific configuration, in the embodiment of FIG. 1, there are twelve hierarchies from a hierarchical well 1 close to the bottom of the ship to a top well 12, each of wells 1 to 3 is 1.8 m, well 4 and well 4. 5 is 2. 2m, well 6 is 2.9m, wells 7-11 are 2.2m each, and well 12 is 1. It has a deck spacing of 8 m and thus a level height. RV vehicles have a vehicle height of around 1.7 m. Therefore, as shown in FIG. 1, at a distance between decks of 1.8 m, 2.2 m, and 2.9 m, it is possible to support loading of a 100% RV vehicle.

The wells 4 and 5 can adjust the distance between the decks in the range of 2.2 to 2.6 m and 2.2 to 1.8 m as required, that is, they are partially movable decks. In some cases, well 5 may be removed and wells 4 and 6 may have one large inter-deck distance, e.g. 3m can be formed. Similarly, wells 6 and 7 have adjustable inter-deck distances in the range of 2.9-3.3 m and 2.2-1.8 m, respectively, that is, they can be partially movable decks. In some cases, well 7 can be removed and well 6 and well 8 can be brought to one large deck distance, for example, 5.0 m. Similarly, the wells 8 and 9 can adjust the distance between the decks within the range of 2.2 to 2.6 m and 2.2 to 1.8 m as necessary, that is, they are partially movable decks. In some cases, well 9 may be removed and well 8 and well 10 may form one large deck distance, e.g. 3m. Even when a part of the hold is formed as a movable deck in this way, as long as the minimum inter-deck distance of 1.730 to 1.900 m can be adjusted, the loading of RV vehicles is the same as for the fixed deck. Optimal hold is guaranteed.

In addition to the above, it is also possible to provide a new deck with a large inter-deck distance by removing the center deck among the three decks adjacent to each other for the wells 1 to 12.

[Effect of the invention]

 The transport ship, such as a multi-layer deck car, according to the present invention allows a large number of RVs to be loaded without reducing the number of loaded vehicles, and allows the space between the decks of the hull to be used as efficiently as possible. Shipping companies get their money from the freight of their cargo, but in the case of a vehicle, the freight is calculated by the volume of the loaded vehicle. In other words, how to effectively use the limited space inside the hull as a loading space is the mission of the hull design, and an optimal structure that meets the needs of today's large volumes of RVs has a major impact on the shipping company's economy. Has the effect of giving.
