Description

How to ship using a ship or ship

The present invention relates to a conveying method using a ship and a ship, and more particularly, to a method of conveying an amphibious vehicle to a vehicle deck, which is capable of oscillating, preferably lifting, Which is capable of securing a large space of an amphibious vehicle, and a conveying method using the vessel.

For example, as described in Japanese Patent Laid-Open Publication No. 2014-108689, a vehicle capable of traveling on the sea and land can be used as a vehicle for running on land, a crawler (crawler) Amphibious vehicles equipped with water jet propulsion devices (such as screw propellers and water jets) are known. Amphibious cars are being used as rescue vehicles or disaster countermeasures in addition to military vehicles.

In the past, amphibious vehicles were launched from the shore (shallow shoals) to the waterfront, and amphibious vehicles frequently moved to active water areas. However, since the amphibious vehicle is not a special structure for water movement, the movement speed in the water phase is slower than that of the ship, and the fluctuation at the time of water movement is also large. Therefore, if the active water area is far from the coast, it takes a lot of time to move the water. In addition, the crew of the amphibious car has a problem of seasickness because it stays in the car for a long time in a large bumpy car. Therefore, there is a need for a way to move an amphibious vehicle between the active water area and the coast in a short time.

Published Patent Publication No. 2014-108689

Therefore, the present inventor can remarkably shorten the time required for water transfer if the amphibious vehicle is mounted on a ship and the ship transports the amphibious vehicle between the shore and the active water area. Further, During the bounce, the crew of the amphibious vehicle was able to sit onboard, thus reducing the possibility of crew seasickness. However, as a method of conveying using this vessel, it is necessary to lift the amphibious vehicle from the car deck of the vessel to the water deck, preferably from the water to the deck of the vessel, in the active water area, .

In order to achieve the above object, the present invention provides a watercraft,

A vehicle deck on which the amphibious vehicle is mounted and an inclined deck inclined downward from the rear end portion to the aft end portion of the vehicle deck to be part or all of the line width direction .

According to this configuration, it becomes possible to oscillate the amphibious vehicle from the vehicle deck to the water main while having a relatively simple structure. In addition, by driving or sliding the amphibious vehicle to lower the inclined deck, the amphibious vehicle is oscillated as the aquamarine, thereby making it possible to quickly launch the amphibious vehicle to the aquamarine. Therefore, it is particularly useful when a plurality of amphibious cars are oscillated in a short time. In addition, since the seawater that has passed from the forward side to the deck of the vehicle can be discharged from the inclined deck of the rear portion, the drainage of seawater is greatly improved.

As a method of oscillating the amphibian vehicle from the vehicle deck by water, for example, as shown in Fig. 8, a rampway is installed at the rear end of the vehicle deck, and the rampway is inclined downward toward the water It is conceivable to extend the amphibious vehicle by running or sliding the amphibious vehicle from the deck of the vehicle through the rampway and oscillating it by water.

However, in general ships, since the height (freeboard) from the water surface at the rear end of the vehicle deck is high, it is necessary to install a long rampway in order to heighten the height position of the tip end of the rampway have. Further, when lifting the amphibious vehicle from the watercraft to the vehicle deck, it is necessary to further lower the height position of the tip end of the lampway, so it is necessary to provide a longer lampway.

When the lampway is placed over the water, the tip end of the lampway is not supported and is in the same state as the cantilever beam. Therefore, when the lampway is long, the load applied to the junction (lamp hinge) between the lampway and the hull becomes very large. Also, the weight of the amphibious vehicle is very large, for example, about 20 to 30 tons, so it is difficult to install a long rampway that can withstand the weight of the amphibious vehicle. Even if it is possible, a large auxiliary equipment for supporting the lampway is required.

In addition, as a method of oscillating another amphibious vehicle from the deck of the vehicle to the watercraft, a dock descent method for a ship, for example, may be applied to an amphibious vehicle. Specifically, for example, as shown in Fig. 9, a dock deck is provided on the stern side of a vehicle deck to move the amphibious vehicle from the vehicle deck to the dock deck, thereby flooding the dock deck, I can think of a way. However, in this case, the space of the vehicle deck on which the amphibious vehicle is mounted narrows because it is necessary to secure the space of the runway connecting the space of the dock deck and the deck of the vehicle to the dock deck.

Compared with the method of oscillating these amphibious cars from the vehicle deck to the aquaplane, the space required by the inclined deck is much smaller than the space required when the dock deck is installed on the stern side of the vehicle deck Therefore, it is possible to secure a large space of the vehicle deck on which the amphibious vehicle is mounted.

In the ship, if the rampway is provided at the rear end of the inclined deck, the amphibious vehicle is raised from the waterpipe to the rampway and the inclined deck so that the amphibious vehicle can be lifted to the vehicle deck . Further, when the amphibious vehicle is made to oscillate, the amphibious vehicle can travel or slide on the rampway until the amphibious vehicle is placed on the ramp by arranging the rampway at the rear end of the inclined deck to extend to the water, It is possible to reduce vibrations and shocks generated when the amphibious vehicle is driven, and to oscillate the amphibian vehicle more smoothly. In addition, since the ship is provided with the inclined deck, the height from the water surface of the rear end portion of the inclined deck can be reduced. Therefore, even when the amphibious vehicle can be lifted from the watercraft to the vehicle deck, May be short. That is, since it can be constructed with a short lampway, it can withstand the weight of an amphibious vehicle.

If the ship is provided with a rampway on the forward side, it becomes possible to move the amphibious vehicle between the shore and the vehicle deck only by the ship without using other loading facilities. Therefore, It is highly versatile as a ship that carries out transportation between water bodies.

In the ship, if the inclination angle of the inclined deck relative to the vehicle deck is fixed at 10 degrees or more and 20 degrees or less, the angle of inclination of the inclined deck can frequently rise to the inclined deck The amphibious vehicle can be lifted frequently, but the inclination angle can be increased as much as possible, so that the space of the vehicle deck can be secured to a large extent.

In other words, if the angle of inclination is larger than 20 degrees, it becomes difficult for the amphibious car to ascend the inclined deck frequently, so that a facility such as a winch is required to lift the amphibious vehicle from the waterpark to the vehicle deck. On the other hand, if the inclination angle is less than 10 degrees, the length of the inclined deck required to lower the height from the water surface of the stern end of the inclined deck becomes long, which makes it difficult to secure the space of the vehicle deck.

And a tilting mechanism capable of changing the inclination angle of the inclined deck with respect to the vehicle deck. The inclination angle of the inclined deck with respect to the vehicle deck by the tilting mechanism is 0 degrees or more, The inclination deck is inclined downward with respect to the vehicle deck only when the amphibious vehicle is oscillated and / or lifted. In other cases, the inclination of the inclined deck relative to the vehicle deck By making the inclination deck parallel to the vehicle deck by setting the angle to 0 degrees, it becomes possible to mount the amphibious vehicle on the inclined deck. That is, by effectively utilizing the inclined deck as a part of the vehicle deck, the number of amphibious vehicles can be increased.

In order to achieve the above object, the present invention provides a conveying method for conveying an amphibious vehicle to an active water body, the method comprising the steps of: providing the amphibian vehicle on a ship front side of a vehicle deck on which the amphibious vehicle is mounted; The amphibious vehicle is caused to descend from the inclined deck inclined downward from the rear end portion to the aft end portion of the amphibious vehicle so as to oscillate.

According to this method, the amphibious vehicle can be moved between the active water area and the coast in a short time by returning the amphibious vehicle from the ship. In addition, it becomes possible to oscillate the amphibious vehicle from the vehicle deck to the waterpath with a relatively simple structure. Also, by driving or sliding the amphibious vehicle down the sloping deck, the amphibious vehicle is allowed to enter the aquifer, making it possible to launch the amphibious vehicle quickly to the aquifer. Therefore, it is particularly effective when a plurality of amphibious vehicles are oscillated in a short time.

Further, since the space required by the inclined deck is very small as compared with the space required when the dock deck is installed on the stern side of the vehicle deck, the space of the vehicle deck on which the amphibious vehicle is mounted can be largely secured .

Wherein the rampway is connected to the inclined deck at the rear end of the inclined deck, and when the amphibious vehicle is oscillated from the vehicle deck to the waterpath, the rampway is extended up to the water And the amphibious vehicle is caused to oscillate with the water droplet by causing the inclined deck and the rampway to descend, and when the amphibious vehicle is lifted from the water main to the vehicle deck, the stern rampway is arranged so as to extend to the water And the amphibious vehicle is lifted to the deck of the vehicle by raising the rampway and the inclined deck, the following effects can be obtained.

According to this method, it is also possible to salvage amphibious cars from ships in active waters and to return amphibious cars from the active waters to the coast. In addition, when the amphibious vehicle is oscillated, the amphibious vehicle can travel or run on the rampway until just before the aquaplaning, so that the vibration and impact generated when the amphibious vehicle enters the aquarium can be reduced, It becomes possible to oscillate an amphibious car.

In addition, in the conveying method using the ship, since the height from the water surface of the rear end portion of the inclined deck can be made lower by providing the inclined deck, even when the amphibious vehicle can be lifted from the water main to the deck, The lampway installed at the rear end of the inclined deck may be short. That is, since it can be constituted by a short lampway, it can withstand the weight of an amphibious vehicle sufficiently.

The method according to claim 1, wherein, when the amphibious vehicle is accommodated in the vehicle deck from the shore and / or when the amphibious vehicle is lifted from the deck to the shore, By moving the amphibious vehicle by placing the rampway over the coast, it becomes possible to move the amphibious vehicle between the coast and the vehicle deck only by the ship without using other loading facilities, And as a ship carrying it, highly versatile.

In the method of conveying using the ship, when the amphibious vehicle is oscillated from the vehicle deck to the aquaplane and / or when lifting the amphibious vehicle from the aquisition to the deck of the car, the quantity of ballast water of the ship is increased The height from the water surface of the rear end portion of the inclined deck can be further lowered so that the amphibious vehicle can be oscillated and / or lifted more smoothly. When the rampway is provided at the rear end of the inclined deck, the length of the rampway can be further shortened.

According to the conveying method using the ship and the ship of the present invention, the amphibious vehicle can be moved between the active water area and the coast in a short time by conveying the amphibious vehicle from the ship. Further, it is possible to oscillate the amphibious vehicle from the vehicle deck to the water main, while having a relatively simple structure in which an inclined deck inclined downward from the rear end portion to the stern end portion of the vehicle deck is provided. In addition, the amphibious vehicle can be driven into the aqueduct by driving or sliding the amphibious vehicle to lower the inclined deck, thereby rapidly launching the amphibious vehicle into the aqueduct.

Further, since the space required by the inclined deck is very small as compared with the space required when the dock deck is installed on the stern side of the vehicle deck, the space of the vehicle deck on which the amphibious vehicle is mounted can be largely secured .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a carrying method using a ship and a ship according to an embodiment of the present invention will be described with reference to the drawings.

The vessel of the embodiment according to the present invention is a vessel specialized in carrying an amphibious vehicle. This amphibious vehicle refers to a vehicle capable of driving on water and land. Specifically, for example, a military vehicle, a water-rescue vehicle, a disaster, or the like having a running tread, a crawler (crawler), a water running water-propelling device (a screw propeller and a water jet) Countermeasures vehicles.

1 to 3, the ship 1 according to the first embodiment of the present invention is provided with a vehicle deck 5 on which an amphibious vehicle 20 is mounted, And an inclined deck 6 which is inclined downward from the front end portion 3a to the rear end portion 3a. In this embodiment, the upper deck 4 of the ship 1 is formed by the vehicle deck 5 and the inclined deck 6, and the vehicle deck 5 and the inclined deck 6 are fixed to the hull. That is, the inclination angle? Of the inclined deck 6 with respect to the vehicle deck 5 is fixed.

As shown in Fig. 1 (b), the inclined deck 6 of this embodiment is provided at the center in the width direction of the hull, and the width W of the inclined deck 6 is smaller than the width of the amphibious vehicle 20 The passage width W is set to 3 m to 5 m. In this embodiment, a part of the line width in the line width direction is constituted by the inclined deck 6. However, the entire line width of the ship 1 may be constituted by the inclined deck 6. [ Further, a plurality of inclined decks 6 may be provided with respect to the line width direction.

As shown in Fig. 3, the inclination angle [theta] 1 of the inclined deck 6 with respect to the vehicle deck 5 is greater than 0 degrees and not more than 40 degrees, preferably not less than 0 degrees and not more than 20 degrees, It may be 10 degrees or more and 20 degrees or less.

When the inclination angle 1 is larger than 0 and smaller than 40 degrees with respect to the vehicle deck 5 and the inclination angle 1 is smaller than the inclined angle of the amphibious vehicle 20 with respect to the steep deck 6, To a state in which it can go down to the state.

When the inclination angle? 1 of the amphibious vehicle 20 is greater than the inclination angle? 1 of the inclined deck 6 with respect to the vehicle deck 5 is greater than 0 degrees and less than 20 degrees, Can be set within a range in which the impact and vibration when entering into the water can be made smaller.

If the inclination angle? 1 of the amphibious vehicle 20 is larger than the inclination angle? 1 of the inclined deck 6 with respect to the vehicle deck 5 is 10 degrees or more and 20 degrees or less, It is possible to increase the angle of inclination as much as possible while ensuring that the space of the vehicle deck 5 can be secured to a large extent.

In other words, the maximum value of the inclination angle at which the amphibian 20 can be lowered in a stable state with the amphibian 20 slid is about 40 degrees, and the inclination angle at which the amphibian 20 can travel and descend to a more stable state The maximum angle is about 20 degrees. That is, if the inclination angle? 1 is larger than 40 degrees, the inclination becomes too great, and it becomes difficult for the amphibious vehicle 20 to descend the inclined deck 6 in a stable state. If the inclination angle? 1 is greater than 20 degrees, the amphibious vehicle 20 can descend the inclined deck 6 in a stable state even if the inclination angle? 1 is 40 degrees or less. However, It becomes difficult to control the entry speed of the amphibian 20 into the aqueduct. Therefore, the impact or vibration generated when the amphibian 20 enters the aquarium is somewhat large. On the other hand, if the inclination angle? 1 is less than 10 degrees, the inclination angle? 1 required to decrease the height H from the water surface of the stern end 6a of the inclined deck 6 The horizontal distance L1 (see Fig. 1 and Fig. 2) becomes longer, which is disadvantageous in securing the space of the vehicle deck 5.

The height H (freeboard) from the planned load water line DWL of the rear end portion 6a (stern end portion 3a) of the inclined deck 6 is 0 m or more and 1 m or less, preferably 0.3 m or more Further, it may be 0.6 m or less.

The height H from the planned load water line DWL of the rear end portion 6a of the inclined deck 6 is set to 0 m

Of the inclined deck 6 is less than 1 m and the horizontal distance L1 of the inclined deck 6 can be made as short as possible while the amphibious vehicle 20 can oscillate safely from the inclined deck 6 with water, It is possible to secure a large space of the vehicle deck 5.

The height H of the rear end portion 6a of the inclined deck 6 from the planned load water line DWL,

The inclined deck 6 can be inclined to a greater extent than the amphibious vehicle 20 in the range of impact or vibration when the amphibious vehicle 20 enters the aqueduct 6 from the inclined deck 6, The horizontal distance L1 of the vehicle deck 5 can be shortened.

The horizontal distance L1 of the inclined deck 6 in the direction of the skipper may be, for example, 3% or more of the waterline length Lpp of the ship 1 and 30% or less. Alternatively, the horizontal distance L1 in the ship skeleton direction of the inclined deck 6 may be 4 m or more and 15 m or less, for example. When the horizontal distance L1 of the inclined deck 6 in the direction of the ship's skid is set to these values, the amphibious vehicle 20 is inclined with respect to the inclined deck 6 ) Can be safely oscillated.

In other words, when the horizontal distance L1 is shorter than 3% of the inter-waterline length Lpp, even if the horizontal distance L1 of the oblique deck 6 is increased to some extent, The inclination angle? 1 of the inclined deck 6 with respect to the vehicle deck 5 can be made smaller so that the amphibious vehicle 20 can oscillate the inclined deck 6 more safely . On the other hand, if the horizontal distance L1 is longer than 30% of the waterline length Lpp of the ship 1, the space occupied by the inclined deck 6 becomes large, It becomes difficult to do.

The length L2 of the inclined deck 6 shown in Fig. 3 may be set longer than the wheel base (crawler grounding length) of the amphibious vehicle 20 to be mounted. When the length L2 of the inclined deck 6 is made longer than the wheel base of the amphibious vehicle 20 to be mounted, when the amphibious vehicle 20 descends the inclined deck 6, The crawler can descend the inclined deck 6 in the state that all the crawlers are grounded on the inclined deck 6 and can enter the aquifer with the inclination angle? 1 of the inclined deck 6. Therefore, it becomes possible to oscillate the amphibian 20 in a more stable state.

Specifically, since the wheel base of the amphibian 20 is approximately 4 m to 8 m, the length L2 of the inclined deck 6 may be 4 m or more and 15 m or less. When the length L2 of the inclined deck 6 is longer than 4 m, even when the wheel base of the amphibious vehicle 20 is longer than 4 m, the amphibious vehicle 20 can be stabilized in a somewhat stable state, It is possible to descend. If the length L2 of the inclined deck 6 is longer than 15 m, the length of the inclined deck 6 becomes longer than necessary, which is disadvantageous for securing the space of the vehicle deck 5.

The ship 1 further includes a player lampway 9 on the player's side. The player lampway 9 is rotatably connected to a forward ramp hinge portion 9a provided at the front end of the vehicle deck 5. [

Next, a method of conveying the amphibian 20 using the ship 1 will be described. In the following description, the case where the amphibious vehicle 20 waiting at the coast Q is transported to the active water will be described as an example.

First, as shown in Fig. 1, the ship 1 is ridden on the coast Q where the amphibious vehicle 20 stands by, and the player lampway 9 on the bow 2 side is led to the bow lamp hinge 9a ) To the front of the shore (Q). The amphibious vehicle 20 is frequently moved from the coast Q to the vehicle deck 5 via the player rampway 9 to mount the amphibian 20 on the vehicle deck 5. When the amphibious vehicle 20 is mounted, the player lampway 9 on the shore Q is rotated backward around the player lamp hinge 9a so that the player lampway 9 is folded.

Then, the amphibian 20 is transported by the vessel 1 to the active water area. The amphibious vehicle 20 mounted on the vehicle deck 5 is frequently moved in the direction of the stern 3 to stop the amphibian 20 It runs or slides so that the inclined deck 6 descends and is oscillated by water.

Thus, according to the vessel 1, it becomes possible to oscillate the amphibian vehicle 20 from the vehicle deck 5 to the aqueduct with a relatively simple structure. The amphibious vehicle 20 is caused to run or slid so as to lower the amphibious vehicle 20 so that the amphibian 20 can be oscillated by the aquamarine so that the amphibian 20 can be quickly oscillated by the aquamarine. Therefore, it is particularly useful when a plurality of amphibious cars 20 are oscillated in a short time. In addition, since the inclined deck 6 is provided on the stern 3 side, the seawater that has passed from the stern 3 side to the vehicle deck 5 can be discharged from the rear inclined deck 6, .

The amphibious vehicle 20 has a very large weight, for example, about 20 to 30 tons. Therefore, as shown in FIG. 8, the long rampway 7 which can withstand the weight of the amphibious vehicle 20 is installed However, since the inclined deck 6 of the vessel 1 can be formed as a part of the ship, the strength to withstand the weight of the amphibious vehicle can be secured with a relatively simple structure.

9, the space required by the inclined deck 6 of the ship 1 is formed on the side of the stern 3 of the vehicle deck 5 with the dock deck 30, the vehicle deck 5, Compared to the space required when the main body 31 connecting the dock deck 31 is installed. Therefore, if the size of the hull is the same, the ship 1 can secure a larger space of the vehicle deck 5 on which the amphibian 20 is mounted than the ship 1Y shown in Fig.

Since the ship 1 is provided with the player rampway 9 on the side of the bow 2, the amphibian 20 can be driven only by the ship 1 without using other loading facilities, It becomes possible to move between the decks 5. Therefore, it is highly versatile as a ship that carries the conveyance between the coast (Q) of the amphibious vehicle 20 and the active water area.

In the present invention, the space for the vehicle deck 5 is secured by providing a short oblique deck as in the case of the ship 1 of the first embodiment shown in Figs. 1 to 3. However, The shape of the ship 1A may be the same.

The height H of the rear end portion 6a of the inclined deck 6 from the water surface is made low by extending the inclined deck 6 having a small inclination angle? 1 in the shipboard direction. The amphibious vehicle 20 can be mounted on the inclined deck 6 during the course of travel if the inclination angle? 1 of the inclined deck 6 is set to, for example, greater than 0 degrees and smaller than 5 degrees, The deck 6 can be used as the vehicle deck 5. As a result, it becomes possible to mount a large number of amphibious cars 20 on the inclined deck 6 and the vehicle deck 5. The configuration in which the inclined deck 6 having a small inclination angle? 1 is provided to such an extent that the amphibian 20 can be mounted as in this embodiment is effective in the case where the freeboard of the vehicle deck 5 can be made low This is useful when the captain is long.

Next, the ship 1B according to the third embodiment of the present invention and the conveying method using the ship 1B will be described with reference to Fig. 5. Fig.

The ship 1B further includes a rampway 7 at the rear end 6a of the inclined deck 6 of the ship 1 of the first embodiment shown in Figs. The other configuration is the same as that of the vessel (1).
