Description

  The present invention relates to a ship conveyance device used when landing a marine vessel (mainly a small vessel such as a boat).

In a marina where small ships are moored, carts that move from below the sea level to the land are used on the slopes when landing or launching ships that stop in the harbor. That is, first, a carrier for ship transportation is placed on a carriage, and these are submerged in the sea. Next, the carriage is moved up on the slope by radio or the like, and the ship is also advanced toward the land. Then, the carrier and the ship are docked when the carriage (with the carrier for transportation) and the ship approach each other on the slope (the ship is placed on the carrier at the correct position and posture).
Japanese Patent Laid-Open No. 10-35586 (Publication date: February 10, 1998)

  However, it is not easy to bring the carriage and the ship close to each other on the slope near the sea surface due to the influence of waves, winds, and tides. This is because it is not possible to accurately grasp the state (position) of the bogie under the sea surface from the ship, and it is necessary to consider tides, and in addition, the ship itself swings due to waves and winds. This is because docking with a ship is the result of trial and error. In addition, since the carrier and the ship are docked in shallow water on the slope, the bottom of the ship may be damaged by the slope while docking is attempted many times. In addition, every time when landing (or launching), the carrier for transportation (often owned by the ship's owner) will be submerged in the sea, so the ship owner will complain that the carrier will be rusted. There was also.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a ship transport apparatus and a ship transport method capable of transporting (landing) a ship on the surface of the water (on the sea) to the land easily, safely and reliably. The point is to provide.

Ships carrying device of the present invention, in order to solve the above problems, the row earthenware pots, movable ship ship transport device on slopes submerged underwater the landing of the ship with a slope having a portion submerged below the water surface A carriage unit for placing a ship to be transported, a ship lifting / lowering unit for hoisting or sending a ship support used for lifting and unloading the ship to be transported, and the transport object A support unit that is provided on the carriage unit so as to be located on the outer sides of the two ship sides of the ship, and that supports the ship lifting unit, and a connection unit for mooring the ship to be transported It is characterized by having.

  According to the above configuration, a ship on the surface of the water (on the sea) can be transported (landed) to the land easily and safely as follows.

  First, the ship transport device is lowered to a portion of the slope below the water surface, and the ship to be transported is moved between the support portions of the ship transport device. And a ship and the said connection part are connected with a rope etc. on the water surface, and the ship which is a conveyance object is moored to a ship conveyance apparatus. Thereby, positioning of a ship and a ship conveyance apparatus in the surface parallel to the water surface is made. Next, the ship support material is wound up by the ship lifting / lowering section, the ship support material is hung on the ship bottom, and the ship is lifted by a predetermined distance. The predetermined distance is, for example, a distance that allows the ship bottom to come close to the water surface (underwater) where the influence of waves is almost eliminated.

  In this state, the ship conveyance device is lifted to the land side along the slope. Then, since the distance between the water bottom (sea floor) and the water surface is reduced, the platform portion of the carriage and the ship bottom are brought closer. Until the bogie part and the pedestal part come into contact, the ship support material is sent out from the ship lifting part so that the position of the bottom of the ship is maintained at a predetermined position with respect to the water surface. It is preferable to lower it. And when the said base part raises underwater to near the surface of the water, this base part and a ship bottom will contact, and the weight of a ship will be entrusted to a trolley | bogie part. Furthermore, if a ship conveyance apparatus (cart part) is pulled up to the land side as it is, a ship can be landed.

  As described above, the ship transport device of the present invention connects the connecting portion of the ship transport device and the ship on the water surface to position the ship transport device and the ship, and the bottom of the ship is brought near the water surface by the ship lifting / lowering portion. After raising the ship until it comes, it is transported along the slope to the shallows (land side). Thus, since positioning between both is performed in the state which stopped the ship which is a conveyance object, and a ship conveyance apparatus on the water surface, positioning can be performed safely and correctly. In addition, since the ship is moored to the ship transport device and transported on the surface of the water in a suspended state, the ship is not affected by waves or wind during transport, and the positioning state can be maintained with high accuracy. it can.

  As a result, after positioning on the surface of the water, simply pulling up the ship transport device (cart) to the land side, so that the cart's platform and the bottom of the boat automatically move in the direction of travel of the cart and the horizontal direction perpendicular thereto. ) When it approaches without slipping and the pedestal part rises to the surface of the water, the ship can be safely mounted (docked) on the trolley at the correct position.

  As a result, docking must be attempted many times due to the effects of waves and winds, or the effects of tides, resulting in problems such as being unable to place the ship in the correct position or damaging the bottom of the ship on the slope. Can be solved.

  Furthermore, since the carrier for transportation (corresponding to the ship to be transported, which is often owned by the ship owner) is not used for landing (draining), the carrier for carrier is rusted and complaints from the ship owner It can also solve problems such as

In order to solve the above-described problems, the ship transport method of the present invention uses a ship having a portion that sunk under the surface of the water and uses a ship transport device that can move on the slope that is sunk under the surface of the water to bring the ship on the water to land. A ship transport method for transporting, wherein the ship to be transported is moored in a ship transport device including a carriage unit and a ship lift unit for lifting the ship on the water located on the slope. a step, by a predetermined distance lifting process the ship by the ship Agefu portion, a step pulled Ru along the slope of the ship conveying device while lifting the ship, the lifting vessels, and the ship bottom is the truck until contacts, as the ship's bottom position is maintained in position relative to the water surface, the ship will reduce the vessels against the ship Agefu unit, a step of placing on the truck, the ship Carrying the ship while being placed on the transfer device Pulling the device along the slope, it is characterized by comprising the step of unloading the ship.

  According to the ship transport method, first, a ship to be transported is moored to the ship transport device on the sea located on the slope. Thereby, it is possible to safely and accurately perform positioning (positioning in a plane parallel to the water surface) between the ship to be transferred and the ship transfer device. Next, the ship is lifted a predetermined distance. The predetermined distance is, for example, such a distance that the bottom of the ship rises to near the sea surface (underwater). Thereby, the rocking | fluctuation of the ship by the influence of a wave can be suppressed. Next, the ship conveyance device is pulled up along the slope while the ship is lifted. As a result, the pedestal part of the carriage and the bottom of the ship approach each other without deviation (in the traveling direction of the trolley and the horizontal direction perpendicular thereto), and when the pedestal part rises to near the surface of the water, the ship is safely placed in the correct position Can be placed (docked) on the part. And the landing of the said ship is completed by pulling up a ship conveyance apparatus along a slope in this state.

  As described above, according to the ship conveyance device of the present invention, a small ship can be landed or launched easily, safely and accurately using a slope inclined from the sea to the land.

  Fig.5 (a) is a top view of the marina where the ship conveyance apparatus 1 shown to Fig.1 (a) (b) is used. FIG. 5B is a cross-sectional view of the marina shown in FIG.

  As shown in FIGS. 5 (a) and 5 (b), the marina includes an inclined surface 21, two rails 20 provided on the inclined surface 21, a ship receiving stage 22, a ship transfer device winder 23, A pulley 24 and a control panel 25 are provided.

  The ship transporting device winder 23 winds the wire W through the pulley 24 and pulls up the ship transporting device 1 connected to the wire W from the sea together with the ship S, or sends out the wire W through the pulley 24 to the wire W. It is for taking down the connected ship conveyance apparatus 1 with the ship S in the sea. The rail 20 is a traveling rail that is used when the ship conveyance device 1 moves up and down the slope 21 (the wheel 3y of the carriage 3 rotates). Moreover, the ship receiving stage 22 is provided in the plane part connected with the topmost part of the slope 21, and the ship S landed with the ship conveying apparatus 1 here is mounted on the carrier for conveyance (not shown). The control panel 25 controls the winding or sending operation of the wire W in the ship transporting device winder 23 and also controls the winding or sending operation of the belts 6x and 6y in the ship unloading devices 5a and 5b of the ship transporting device 1. To do.

  Below, the procedure at the time of landing the ship S by the ship conveyance apparatus 1 which concerns on this Embodiment is demonstrated in detail using Fig.3 (a)-(d) and Fig.4 (a) (b). Here, FIGS. 3 (a) to 3 (d) and FIGS. 4 (a) and 4 (b) are side views for explaining a ship transport procedure when the ship transport apparatus 1 is used.

  First, as shown in FIG. 3A, the above-described ship conveyance device 1 is lowered along the rail 20 to a portion below the water surface of the slope 21. Here, as described above, the ship transport device 1 is connected to the ship transport device winder 23 in the marina via the wire W (see FIG. 5A), and operates the control panel 25 (wirelessly operated or fixed). By operating the buttons on the operation panel, the ship transfer device winder 23 can be operated to lower the ship transfer device 1 to the initial position (see FIG. 5A). Here, the belts 6x and 6y connected to the ship lifting / lowering devices 5a and 5b are in a slack state on the carriage unit 3 as shown in FIGS. 3 (a) and 1 (b).

  Next, the ship S to be transported is moved between the support portions 7a and 7b of the ship transport device 1, and the two rope knots 8a provided on each of the two columns of the support portion 7a and the ship S are connected. The two predetermined locations are connected by the rope R, and the two rope knots 8b provided on the two struts of the support portion 7b and the predetermined two locations of the ship S are connected by the rope R, respectively. . As a result, the ship S is connected to the ship transport device 1 at four positions in the front and rear (head / stern direction) and left and right (ship side direction), and positioning of the ship S and the ship transport device 1 in a plane parallel to the water surface. Is made.

  Next, as shown in FIG. 3 (b), the belts 6x and 6y in a slack state on the carriage unit 3 are wound up by the ship lifting and lowering devices 5a and 5b, and the belts 6x and 6y are hung on two places at the front and rear of the ship bottom. The ship S is lifted a predetermined distance. Here, it is preferable to lift the ship S until the ship bottom comes to the vicinity of the sea surface (underwater) where the influence of waves is almost eliminated.

  Next, as shown in FIG. 3C, in this state (the state where the ship S is lifted), the ship transport device 1 is pulled up along the slope 21 to the land side (shallow side). Also here, the ship conveyance device 1 can be pulled up via the wire W by operating the control panel 25 provided in the marina (wireless operation or button operation of the fixed operation panel). As a result, the distance between the slope (sea floor) on which the rail 20 is provided and the water surface is reduced, so that the base portion 3x of the carriage unit 3 and the ship bottom (preferably located in the sea near the water surface) approach each other.

  Here, until the base part 3x of the cart part 3 and the ship bottom of the ship S come into contact with each other, the ship raising / lowering devices 5a, 5b to the belt 6x, so that the position of the ship bottom is maintained at a predetermined position (depth) from the water surface. It is preferable to send out 6y and lower the ship S with respect to the ship lifting / lowering devices 5a and 5b. At the same time, the knot of the rope R in the rope knots 8a and 8b also moves toward the sea surface. Therefore, it is preferable that the rope knots 8a and 8b have a predetermined length in a direction perpendicular to the sea surface as shown in FIG.

  As shown in FIG. 3 (d), when the platform portion 3x rises to the vicinity of the water surface under the sea, the platform portion 3x and the ship bottom come into contact with each other, and the weight of the ship S is deposited in the cart section 3x. Further, when the ship transport device 1 is lifted to the land by the ship transport device hoisting machine 23 and the bottom of the ship comes out on the water surface, the buoyancy applied to the ship S becomes almost 0, and the entire weight of the ship S is entrusted to the cart unit 3. . Thereby, the landing (draining) of the ship S is completed.

  In addition, after completion of draining, as shown in FIG. 4A, the ship transporting apparatus 1 is pulled up to the ship receiving stage 22 which is a plane part. Then, as shown in FIG. 4 (b), the ship is moved to a position where the carrier 27 corresponding to each ship S (which is often owned by the owner of the ship S) can be inserted by the ship lifting / lowering devices 5a and 5b. S is lifted, and the ship S is transferred to the carrier 27 for transportation to the land mooring site.

  On the other hand, when the ship S placed on the carrier 27 for transportation is launched to the sea surface, the following procedure is used.

  First, the ship S placed on the transport carrier 27 is moved together with the transport carrier 27 from the land mooring station to the ship receiving stage 22 (see FIG. 5A), and the ship transport device is lifted by the ship transport device winder 23. 1 is moved to the front of the ship receiving stage 22, and the carrier 27 for transport is inserted between the support portions 7 a and 7 b of the ship transfer device 1. Next, the ship S on the carrier 27 is lifted by the ship lifting / lowering devices 5a and 5b of the ship carrier 1, and the carrier 27 is removed. And the ship conveyance apparatus 1 is lowered | hung to the sea surface along the rail 20 on the slope 21 by the ship conveyance apparatus winding machine 23 in the state as it is. When the ship transport device 1 reaches a predetermined position on the sea, the ship S lifted by the ship lifting / lowering devices 5a and 5b is lowered, and the ship S is launched to the sea surface.

  Thus, the ship transport device 1 of the present invention connects the support portions 7a and 7b (rope pipes 8a and 8b) and the ship S of the ship transport device 1 and the ship S on the sea surface. The ship S is lifted so that the bottom of the ship comes close to the sea surface by the ship lifting / lowering devices 5a and 5b, and is transported (raised) to the land along the slope 21 as it is.

  Accordingly, the ship S is hardly affected by waves or winds during the transfer on the sea surface, and the ship transfer device 1 (cart unit 3) is not affected by the tides. By simply pulling to the land side with the hoisting machine 23, the platform portion 3x of the carriage section 3 and the ship bottom automatically approach each other without shifting (in the traveling direction of the carriage section 3 and the horizontal direction perpendicular thereto), and the platform portion When 3x rises to the vicinity of the water surface in the sea, the ship S can be safely (docked) on the cart unit 3 at the correct position.

  This solves the problem that the ship swings due to the influence of waves and wind, and the carriage (base part) and the bottom of the ship shift, and the ship cannot be placed at the exact position of the carriage or the bottom of the ship is damaged by the slope. can do. Furthermore, since the carrier 27 for transporting (draining) or launching (which is often owned by the owner of the ship S as described above) is not used, the carrier 27 is rusted and the owner of the ship S is attached. Can also solve problems such as complaints.

  The ship conveyance device of the present invention can be used when a small ship on the sea surface or lake surface is landed or a small ship on land is launched into the sea or lake using a slope inclined from the land to the water.
