Description

  The present invention relates to an automobile carrier and a method for mounting an automobile in an automobile carrier, and more particularly, an automobile carrier capable of mounting a large number of automobiles with a relatively simple configuration and capable of responding to various vehicle heights of the automobiles to be mounted. The present invention relates to an automobile mounting method in an automobile carrier ship.

  In order to increase the loading capacity of a vehicle in an automobile carrier ship, it is possible to cope with the difference in vehicle height of the mounted vehicle by using a liftable deck called a liftable deck between the upper and lower decks fixed to the hull. Has been done. For large vehicles with high vehicle height, the liftable deck is raised and mounted on the lower deck.For small vehicles with low vehicle height, the liftable deck is lowered and the lower deck and It is installed on both the double decks.

  As an automobile carrier equipped with this liftable deck, for example, in a split type liftable deck formed by arranging a plurality of deck plates in parallel, it can move in any direction between the installation position and the storage position. Each set of drums is lifted and lowered by winding and unwinding a set of wire ropes with a set of drums that are linked and driven by only one lifting drive source. 2. Description of the Related Art A liftable deck device for an automobile carrier ship that is stopped with a sagable stopper has been proposed (see, for example, Patent Document 1).

  In addition, liftable car decks installed between the upper and lower fixed car decks are lifted up and down to remove some central guide posts in the cargo area of the car carrier, improve traffic on the car deck, and improve cargo handling efficiency. In addition, one side of the ship side of the liftable car deck is sandwiched between at least two sets of front and rear, left and right three-way rollers or guide plates between the rails of the guide post with the hull, and the corresponding other side has at least two sets of four There has been proposed a car carrier having a liftable car deck that forms a car deck in a state of a lowest point, an intermediate position, and an uppermost part from a suspension device composed of a three-bar joint mechanism (see, for example, Patent Document 2).

  In addition, in order to increase the mounting space of automobiles on automobile carriers, a hull that can carry vehicles consisting of a boarding deck, upper deck, and lower deck is provided on the hull, and between the loading deck and each deck. The Kurauchi Rampway for moving cars is provided, and a liftable deck that is supported so that it can be raised and lowered between the boarding deck and the upper deck and that can be loaded with cars, and a liftable deck that is in a predetermined loading position Has proposed a car carrier having a fixed deck on which a car can be loaded (see, for example, Patent Document 3).

  However, in these automobile carriers, a single liftable deck is provided between the upper and lower decks fixed to the hull so that the liftable deck can be moved up and down. Although it is possible to cope with the difference in height, there is a problem that if an automobile with various vehicle heights is transported at the same time, an empty space is generated in the ship, and the space in the ship cannot be fully utilized.

  In this connection, the upper deck part which can be moved up and down configured to be releasably fixed by the fixing device at each of the position moved individually in the vertical direction and the position moved together in the vertical direction, and Equipped with a lower deck part that can be raised and lowered, and the upper deck part is united with the lower deck part closely overlapped to form a common deck unit, and the upper deck part and the lower deck part are mutually connected There has been proposed a structure for a cargo deck for a vehicle on a ship that can increase the strength of the formed common deck unit and reduce the deflection by acting on (see, for example, Patent Document 4).

  However, in this structure, depending on the cargo to be loaded, the upper deck portion and the lower deck portion are welded, riveted so that the load acting on the upper deck portion can be received by the lower deck portion integrated with the upper deck portion. If the load is relatively stable, it must be permanently joined or removed and integrated by striking, gluing, bolting, or non-bolt removable fixings. This is possible, but if it changes from voyage to voyage, it may be necessary to disassemble the integrated upper deck part and lower deck part. Since the structures are different, there is a problem that two types of deck sections are produced and the top and bottom positions are not mistakenly arranged and workability is deteriorated.

Japanese Patent Laid-Open No. 06-191474 Japanese Patent Laid-Open No. 10-181680 JP 2011-183866 A Japanese Patent No. 4560047

  The present invention has been made in view of the above-described situation, and an object of the present invention is not to further increase the number of liftable decks provided between upper and lower decks fixed to a hull in an automobile carrier equipped with a liftable deck. To provide a vehicle carrier capable of mounting a large number of vehicles and a vehicle mounting method in a vehicle carrier with a relatively simple structure and capable of responding to various vehicle heights of the vehicle to be mounted by forming a plurality of continuous layers. is there.

In order to achieve the above object, an automobile carrier of the present invention is provided between upper and lower decks fixed to a hull, and moves up and down between the upper and lower decks to move to a plurality of preset vertical positions. In a car carrier equipped with a liftable deck that is fixedly supported at the respective upper and lower positions, it has a cargo hold in which two of the liftable decks configured to support a cargo mounted independently are arranged continuously, The fixing support at the upper and lower positions of the liftable deck is performed by inserting a fixing pin provided on the liftable deck side into a fixing hole provided on a support pillar on the hull side, and around the liftable deck. By rotating a wire reel provided on the center side of the liftable deck and loosening the wire fixed to the wire reel, With the spring force that biases the fixing pin outward, the fixing pin protrudes, and the wire reel is rotated in the reverse direction to pull the wire fixed to the wire reel, thereby resisting the spring force. the fixing pin configured to draw, the when the riff Portable deck superposed into two layers provided with a Rifutoka for lifting riffs Portable deck, lower layer of the wire reel and coaxial pinion of the riff Portable deck a first cylinder which meshes to lower the rack for rotating the wire reel, a rack for meshed with the wire reel and coaxial pinion of the upper layer of the riff Portable deck rotates the wire reel The lift car includes a second cylinder that moves up and down.

  According to this configuration, in the car carrier ship, there is a deck called a liftable deck that can adjust the height position from the prior art, and it can handle different types of vehicle heights. By providing the liftable deck with the same structure, the number of cases of vehicle height that can be accommodated in the prior art was about 3 cases, for example, a continuous two-layer liftable deck between fixed decks. If it is arranged and the deck height can be set at an arbitrary position (however, it can be set in advance), the number of vehicle heights that can be loaded can be increased to more than 7 cases. Will be able to increase.

  For example, in an automobile carrier ship with a total length of about 200m, a mold width of around 30m, and a mold depth of around 40m, the deck height can be arbitrarily set by making the liftable deck into two continuous layers. Then, it becomes possible to increase the vehicle deck (car deck), which was 12 layers, to 14 layers, and accordingly, it is possible to increase the number of vehicles loaded per vehicle. In other words, even if the overall height of the car carrier is the same, the vehicle deck can be increased from 12 layers to 14 layers using a continuous two-layer liftable deck according to the vehicle height of the mounted vehicle. It becomes possible to increase the amount of vehicles mounted for two layers of the vehicle deck.

  In addition, the liftable deck is configured to support a single cargo, and the continuous multi-layered liftable deck has the same structure, so the upper and lower liftable decks are fixed. There is no need to fasten and integrate, and even if the cargo changes every voyage, it can be changed quickly, and since there is only one type of liftable deck, there is a problem of misplacement of the upper and lower positions. Does not occur.

  In the above-mentioned car carrier, the fixing support at the upper and lower positions of the liftable deck is performed by inserting the fixing pins provided on the liftable deck side into the fixing holes provided on the support pillar on the hull side. With this configuration, the upper and lower positions of the liftable deck can be fixedly supported with a very simple configuration.

  According to this configuration, the fixing pin can be easily protruded or retracted from the fixing hole provided in the support pillar on the hull side by a simple operation of rotating the wire reel. Become.

  In the above-described automobile carrier, it is relatively easy to move up and down the liftable deck and include a lift car that includes a cylinder that moves up and down the rack that rotates the wire reel while meshing with a pinion that is coaxial with the wire reel. With this configuration, the liftable deck can be fixedly supported on the support column, and the fixed support can be released.

  In the car carrier described above, when the lift car overlaps the liftable deck in two layers, a first cylinder that pushes out the rack for rotating the wire reel of the lower liftable deck, and the upper layer When the second cylinder that pushes out the rack for rotating the wire reel of the liftable deck is provided, not only fixing and releasing of the lower liftable deck, but also the upper liftable deck The fixed support and the fixed support can be released.

And the vehicle mounting method in the car carrier for achieving the above object is provided between the upper and lower decks fixed to the hull, and is moved up and down between the upper and lower decks to set a plurality of preset vertical positions. In the vehicle loading method in the car carrier equipped with the liftable deck that is fixedly supported at the respective upper and lower positions, the two liftable decks having a structure for supporting the cargo loaded independently are arranged continuously. A first loading method in which the upper layer of the liftable deck and the lower layer of the liftable deck are stacked or arranged close to each other, and an automobile is not loaded therebetween; and the upper layer of the liftable deck. And a second loading method in which a car is loaded between the lower liftable deck and the lower liftable deck. The wire reel provided on the center side of the liftable deck is fixed by inserting a fixing pin provided on the liftable deck side into a fixing hole provided on the support pillar on the hull side. The lift car is provided with a cylinder that moves up and down the rack that rotates the wire reel by meshing with a pinion that is coaxial with the lift table, and lifts and lowers the lift table on which the liftable deck is mounted, and drives the cylinder to move the liftable the wire reel which is provided on the center side of the deck is rotated by loosening a wire fixed to the wire reel, the spring force for biasing the locking pin outwardly, said support by projecting the fixing pins It is inserted into a fixing hole provided in a pillar, and the liftable deck is fixedly supported to the support pillar, and then the front of the lift car A liftable deck fixing step of lowering the lift table and moving the lift car; and moving the lift car to raise the lift table of the lift car and placing the liftable deck on the lift table from by driving the cylinder, the wire reel reverse rotation is allowed by the pulling of the wire fixed to the wire reel, it pulls the locking pin against the spring force, the supporting column withdrawn from the fixing hole which is provided, wherein the riff Portable deck withdrawal step of releasing the fixed support to said support column riff Portable deck, in the state where the riff Portable deck placed on the lift table, wherein the Rifutoka A liftable device that changes the vertical position of the liftable deck by raising and lowering the lift table. And a step of moving the liftable deck in two layers, the first cylinder provided in the lift car causes a pinion coaxial with the wire reel of the lower liftable deck. The rack for meshing and rotating the wire reel is moved up and down, and meshed with the pinion coaxial with the wire reel of the upper liftable deck by the second cylinder provided in the lift car. The rack for rotating the rack is moved up and down.

  According to this method, a plurality of continuous liftable decks are provided, and a first loading method in which an automobile is not loaded therebetween, and an upper liftable deck and a lower liftable deck are arranged apart from each other. By selectively adopting the second loading method of loading a vehicle on the vehicle, the number of cases that can be handled can be increased with respect to the number of cases of vehicle height that can be handled by the conventional technology.

  In the above-described method for mounting an automobile on a car carrier, the fixing support provided on the top and bottom positions of the liftable deck is inserted into the fixing hole provided on the support pillar on the hull side. By doing so, the vertical position of the liftable deck can be fixedly supported with a very simple configuration.

  Furthermore, in the vehicle mounting method in the above-mentioned automobile carrier ship, a lift car including a cylinder that moves up and down a rack that rotates the wire reel by meshing with a pinion coaxial with a wire reel provided on the center side of the liftable deck, By lifting and lowering the lift table on which the liftable deck is placed, driving the cylinder, rotating the wire reel provided on the center side of the liftable deck, and loosening the wire fixed to the wire reel The fixing pin is protruded and inserted into a fixing hole provided in a support column by a spring force that urges the fixing pin outward, and the liftable deck is fixedly supported on the support column, and then the Fixed liftable deck that moves the lift car by lowering the lift table of the lift car After that, the lift car is moved, the lift table of the lift car is raised, the liftable deck is placed on the lift table, the cylinder is driven, and the wire reel is reversely rotated. By pulling the wire fixed to the wire reel, the fixing pin is pulled out against the spring force and extracted from the fixing hole provided in the support column, and the liftable deck is removed from the support column. The liftable deck detaching step for releasing the fixed support of the liftable vehicle and the lift table of the lift car is moved up and down while the liftable deck is placed on the lift table, thereby changing the vertical position of the liftable deck. Including the liftable deck movement process, these liftable deck fixing processes, liftable deck removal Degree, the riff Portable deck moving step, or to place riff Portable deck at a predetermined position of the fixing holes, so that can be easily or change the arrangement.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an automobile carrier according to an embodiment of the present invention and an automobile mounting method in an automobile carrier will be described with reference to the drawings. The car carrier illustrated here has a total length of about 200 m, a mold width of about 30 m, a mold depth of about 40 m, and a full draft of about 10 m, but the present invention is not limited to this.

  As shown in FIGS. 1 to 3, an automobile carrier 1 according to an embodiment of the present invention is configured by being surrounded by a ship side outer plate 2, a ship bottom 3, and an upper deck 4, and a bridge 5 a at the upper part of the bow portion. The upper structure 5 having a living area 5b is provided, a bow valve 6 is provided below the full load water line at the bow, and a propeller 7 and a rudder 8 are provided below the full load water line at the stern.

  As shown in FIG. 1, the car carrier 1 includes a plurality of continuous cargoes 10 between a cargo hold 10 without a liftable deck and an upper deck 33 fixed to the hull as well as a lower deck 31 fixed to the hull. A lower layer of the liftable deck 32a (two layers in the figure) and a cargo hold 30 provided with an upper layer of the liftable deck 32b are configured. The meaning of “continuously” means that the decks 11, 31, 33 fixed between the two liftable decks 32 a, 32 b are not sandwiched. In FIG. 1, the liftable decks 32a and 32b are indicated by a one-dot chain line. In FIG. 1, the upper deck 33 of the lower cargo hold 30 becomes the lower deck 31 when viewed from the upper cargo pole 30. In addition, the lower liftable deck 32a and the upper liftable deck 32b are configured to support the cargo on which each is mounted independently.

  These liftable decks 32a and 32b move up and down between the lower deck 31 and the upper deck 33, move to a plurality of preset vertical positions, and are fixedly supported at the respective vertical positions. In this case, for example, as shown by the one-dot chain line inside the cargo hold 30 in FIG. 1, the upper and lower positions are moved in a state where the lower liftable deck 32a and the upper liftable deck 32b are stacked or arranged in the vicinity. If the upper and lower positions of the lower liftable deck 32a and the upper liftable deck 32b are moved away from each other, they can be arranged and used in the right two stages. it can.

  The liftable decks 32a and 32b have a length of 10m to 20m, a width of 8m to 12m, and a weight of about 15t to 30t, for example.

  That is, the height ha from the lower deck 31 to the lower liftable deck 32a, the height hb from the lower liftable deck 32a to the upper liftable deck 32b, and the upper deck from the upper liftable deck 32b. The height hc up to 33 and the three heights ha, hb, hc can be used properly. Basically, the heights ha, hb, and hc can be set arbitrarily, but the vehicle height is determined to some extent, and can be set in advance in several patterns and positions.

  On the other hand, in a cargo hold 20 having a single-layer liftable deck 22 such as a conventional car carrier 1X as shown in FIG. 12, the height from the lower deck 21 to the liftable deck 22 is high. The height hx and the height hy from the liftable deck 22 to the upper deck 23 are selectively used, and the range that can be selectively used is smaller than the car carrier 1 of the present invention shown in FIG. I understand that In FIG. 3, it is a three-stage adjustment. This is because the required height is determined to some extent depending on the vehicle type.

  Then, as shown in FIG. 4, fixing pins 65 provided on the side of the liftable deck 32 and fixing pins 65 provided on the top and bottom positions of the liftable decks 32a and 32b (hereinafter 32) are provided on the support column 70 on the hull side. It is configured to be performed by inserting it into the fixing hole 72 of the fixed metal fitting 71. As a result, the vertical position of the liftable deck 32 can be fixedly supported with a very simple configuration.

More specifically, as shown in FIGS. 4 to 6, a plurality (four in FIG. 4) of fixing pins (pin stoppers) 65 provided around the liftable deck 32 (four corners in FIG. 4). By rotating the wire reel 51 of the pin moving mechanism 50 provided on the center side of the liftable deck 32 and loosening the wire 61 fixed to the wire reel 51, the sheave 62 and the intermediate shaft 63 are passed through. by the urging force of the spring 64 for biasing the locking pin 65 on the outside, is projected the locking pin 65, by pulling the wire 61 fixed to the wire reel 51 by reversely rotating the wire reel 51, the spring 64 retract the locking pin 65 against the biasing force. Thereby, the fixing pin 65 can be easily protruded or retracted by a simple operation of rotating the wire reel 51.

That is, in FIG. 5, the fixing pin 65, the biasing force from the spring 64 (repulsive force), always has been a fixed forceps state coming out than the body of the riff Portable deck 32, FIG. 6 as shown, when about a half rotation of the wire reel 51 which is connected to the wire 61, the wire 61 is pulled, the fixing pin fixing pin 65 enters into the fixing hole 72 of the fixing bracket 71 of the support posts 70 It becomes a release state. The state of the fixing metal 71, the fixing hole 72, and the fixing pin 65 is shown in FIGS.

  The rotation of the wire reel 51 is performed by driving a cylinder 81 a (or 81 b) mounted on the lift table 81 and pushing up a rack 66 connected to the pinion 51 a of the wire reel 51. The lifting of the rack 66 is performed by a lift car 80 having cylinders 81 a and 81 b that move up and down the liftable deck 32 and mesh with a pinion 51 a coaxial with the wire reel 51 to rotate the rack 66 rotating the wire reel 51. . As a result, the liftable deck 32 can be fixedly supported on the support column 70 and the fixed support can be released with a relatively simple configuration.

  Further, when the lift car 80 superimposes the liftable decks 32a and 32b into two layers, a rack 66a (rack of the lower liftable deck 32a) for rotating the wire reel 51 of the lower liftable deck 32a is pushed out. A first cylinder 81a and a second cylinder 81b for pushing out a rack 66b (rack of the upper liftable deck 32a) for rotating the wire reel 51 of the upper liftable deck 32b are configured.

  The rack 66a of the lower liftable deck 32a and the rack 66b of the upper liftable deck 32b are positioned symmetrically with respect to the wire reel 51 and opposite to the center of the wire reel 51. The first cylinder 81a and the second cylinder 81b are positioned so as not to overlap. Thereby, not only the fixed support and the fixed support of the lower liftable deck 32a but also the fixed support and the fixed support of the upper liftable deck 32b can be released.

  Next, referring to FIG. 7, a method for changing the fixing position of the two-layer liftable decks 32 a and 32 b by the lift car 80 is a case where the lower-layer liftable deck 32 a is changed in the position load of the upper liftable deck 32 b. An example will be described.

  First, the lift car 80 is moved from the storage location by driving the wheels 84, and the liftable decks 32a and 32b can be placed on the lift table 81 as shown in the left diagram of FIG. It is arranged at the center position of the decks 32a and 32b.

  Next, the out trigger 85 is extended, and the lift car 80 is fixed to the lower deck 31 so that the lift is possible. Thereafter, the lift car 80 is operated to extend the lift cylinder 83 installed between the substrate 82 and the lift table 81 until the lift table 81 comes into contact with the lower liftable deck 32a and rises slightly. The lower liftable deck 32 a is placed on the lift table 81. At this time, the fixing pin 65 is inserted into the fixing hole 72. However, by placing the hole of the fixing hole 72 as a long hole with a margin in the vertical direction, The fine adjustment operation of the lifting cylinder 83 can be facilitated.

Next, as shown in the center diagram of FIG. 7, the first cylinder 81a with the lift table 81 is extended, and the rack 66a is pushed up in the lower liftable deck 32a to rotate the wire reel 51, by pulling the wire 61 fixed to the wire reel 51, pulling the locking pin 65 against the biasing force of the spring 64. As a result, the fixing support of the support column 70 from the fixing bracket 71 is released, and the liftable deck 32 a is supported by the lift table 81. Thereafter, the lifting cylinder 83 of the lift car 80 is further extended, lifted up, and the lift table 81 is raised.

  Then, as shown in the right diagram of FIG. 7, the lift cylinder 80 of the lift car 80 is further extended to lift the lift table 81, and the lower liftable deck 32 a mounted on the lift table 81 is used to lift the upper lift lift. The table deck 32b is supported.

Next, the second cylinder 81b with the lift table 81 is extended, the rack 66b is pushed up in the upper liftable deck 32b, the wire reel 51 is rotated, and the wire 61 fixed to the wire reel 51 is pulled. it is, pull the locking pin 65 against the biasing force of the spring 64. Thereby, the fixing support of the support pillar 70 from the fixing metal 71 is released, and the upper liftable deck 32b is supported by the lift table 81 via the lower liftable deck 32a. As a result, both the lower liftable deck 32a and the upper liftable deck 32b can be released from the support by the fixing bracket 71 of the support column 70.

  Next, as shown in the left diagram of FIG. 8, the lift cylinder 80 of the lift car 80 is extended to lift the lift table 81, and the lower liftable deck 32 a mounted on the lift table 81 is moved to the upper layer. Push up to the position where the liftable deck 32b was.

Next, the first cylinder 81 a with the lift table 81 is contracted, and the rack 66 a is pulled down in the lower liftable deck 32 a to rotate the wire reel 51 and loosen the wire 61 fixed to the wire reel 51. it is, to protrude the locking pin 65 by the biasing force of the spring 64. Accordingly, the fixing pin 65 is inserted into the fixing hole 72 of the fixing metal 71 of the support column 70.

Next, as shown in the central view of FIG. 8, when the second cylinder 81b with the lift table 81 is contracted, the rack 66b is pulled down in the upper liftable deck 32b, and the wire reel 51 is rotated. fixed to 51 the wire 61 is Yurumari, thereby fixing pin 65 by the urging force of the spring 64 protrudes.

  Next, as shown in the right figure of FIG. 8, the lift cylinder 80 of the lift car 80 is contracted, the lift table 81 is lowered, and the lift table 81 is pulled away from the lower liftable deck 32a. At this time, the upper liftable deck 32b is supported by the lower liftable deck 32a fixedly supported by the support pillar 70, and only the lift table 81 is lowered. When the lift table 81 is lowered to the storage position, the outtree 85 is retracted and traveled by the wheels 84 to return the lift car 80 to the storage location.

  Next, an automobile mounting method in the automobile carrier according to the embodiment of the present invention will be described. This method is provided between upper and lower decks 31 and 33 fixed to the hull, and moves up and down between the upper and lower decks 31 and 33 to move to a plurality of preset vertical positions. This is an automobile mounting method for an automobile carrier equipped with liftable decks 32a and 32b fixedly supported in the vertical position, and a plurality of continuous layers of the liftable decks 32a and 32b configured to support the cargo to be mounted alone (a plurality of layers ( In this case, the upper layer of the liftable deck 32b and the lower layer of the liftable deck 32a are stacked or arranged close to each other, and a vehicle is not loaded between them. And a method of selectively adopting the second loading method in which the upper layer of the liftable deck 32b and the lower layer of the liftable deck 33a are spaced apart and a vehicle is loaded between them.
