Description

  The present invention relates to an abdominal tree that supports a marine vessel and a method for supporting the ship, and more particularly, to an easy-to-install abdominal tree and an efficient method for supporting the ship using the abdominal tree.

  In general, when performing maintenance of the hull and the bottom of the ship in the dock, the hull is supported by a main board (keel board) and abdominal board arranged on the bottom of the anchor. The main wood is a wood that is arranged along the center line of the hull, and mainly has a function of supporting the weight of the hull. The abdominal board is a board arranged on both sides of the main board, and mainly has a function of maintaining the balance of the hull. When the ship is supported in the dock using these blocks, the main block and the abdomen are placed on the bottom, the ship is allowed to enter the dock, and the water in the dock is discharged. However, after the ship is bottomed on the main board, the abdominal board is made to reach the ship bottom of the ship.

  By the way, the shape of the ship bottom (inclination gradient, etc.) is not uniform over the entire length of the hull, and the shape of the ship bottom varies depending on the type and size of the ship. You must set the position to place. In addition, the position, height, inclination of the support surface, etc. must be adjusted underwater in order to place the hull on the main board and then place the board on the bottom. Such adjustment often involves diving divers driving wedges between the woodcuts or moving the wheeled wood. Further, in order to facilitate the adjustment of the abdominal tree, a sliding type abdominal tree apparatus (see Patent Document 1), a rotary type abdominal tree apparatus (refer to Patent Document 2), and a piston type abdominal tree apparatus. (See Patent Documents 3 and 4) and the like have already been proposed.

For example, the lower board wood body 11, the middle board wood body 12, and the upper board wood body 13) are configured in multiple stages, and the board bodies other than the lowermost stage (the middle board wood body 12 and the upper board wood body 13) are one step below. It is configured to be slidable along the side surface and the upper surface of the wood board body (the lower board wood body 11 and the middle board wood body 12).

  The lower board wood body 11 is a board body arranged at the lowermost stage of the abdominal board wood 1. The lower board wood body 11 is a board body serving as a base on which other board wood bodies (for example, the middle board wood body 12 and the upper board wood body 13) are loaded. Therefore, it is preferable that the lower board wood body 11 is able to maintain a state where it is arranged at a predetermined position when the ship enters, and has a structure in which buoyancy is unlikely to occur. Specifically, the lower board wood body 11 is a box-like heavy object formed of a steel plate, and a through hole 11a is formed on a side surface 11b thereof. With this flow hole 11a, water can enter the inside of the lower board wood body 11 so that air does not accumulate. The circulation holes 11a are not limited to those formed on the illustrated side surface 11b, and may be formed on other side surfaces, may be formed on the upper surface 11c, or may be formed in plurality.

  Moreover, the lower board wood body 11 is arrange | positioned in the direction which cross | intersects the centerline of a ship along a pair of 1st rail 111,111 arrange | positioned along the both sides of the side surface 11b, and the upper surface 11c. A pair of second rails 112, 112, and a stopper 113 that stops the middle stage wood body 12 slid along the first rail 111 so as to be slidable along the second rail 112.

  The first rail 111 and the stopper 113 are formed of an L-shaped steel material, and the vertical portion constitutes the first rail 111 and the horizontal portion constitutes the stopper 113. In such a steel material, the horizontal portion constituting the stopper 113 is arranged along the second rail 112 arranged on the upper surface 11c of the lower board wood body 11 with the L-shape inverted upside down. The vertical part which comprises is welded to the both side parts of the side surface 11b of the longitudinal direction of the lower board wood body 11, and is fixed to the lower board wood body 11. FIG.

  The second rail 112 is made of a steel material having an L-shaped cross section. Such a steel material is arranged so that the horizontal portion faces each other inward in the short direction so that there is a gap with the upper surface 11c of the lower board wood body 11, and the vertical portion is in the longitudinal direction of the upper surface 11c of the lower board wood body 11. The vertical section is fixed to the lower board wood body 11 by welding the vertical portion to the upper surface 11 c of the lower board wood body 11. With this configuration, the second rail 112 in the form of an insertion slot is formed on the upper surface 11c of the lower board wood body 11 so that a part of the middle board wood body 12 can be inserted in the longitudinal direction. A plurality of set bolts 114 are arranged along the longitudinal direction of the second rail 112 so that a part of the inserted middle board wood 12 can be fixed. Further, the L-shaped members arranged on both sides of the lower board wood body 11 are overhang portions 115 for lifting the lower board wood body 11 with a crane or the like. In addition, the notch part 112a formed in the 2nd rail 112 is an opening part used when transporting the lower board wood body 11 with a crane.

  The middle board wood body 12 is a board body arranged on one stage of the lower board wood body 11. The middle board wood body 12 is configured to be slidable along the side surface 11b and the upper surface 11c of the lower board wood body 11 one step below. Specifically, a pair of first sliders 121 and 121 slidably arranged along the first rail 111 arranged on the lower board wood body 11 and a second rail 112 arranged on the lower board wood body 11. And a pair of second sliders 122, 122 slidably arranged along the line.

  The first slider 121 includes, for example, a first support member 121a extending from the lateral side surface 12a of the middle board wood body 12 and a first support member 121a substantially parallel to the side face 12a of the middle board wood body 12. A second support member 121b coupled so as to extend toward the lower board wood body 11, and a slider connected to the inside of the second support member 121b so as to be engageable with the first rail 111 of the lower board wood body 11. Main body 121c. As shown in FIG. 3, the first slider 121 is formed so as to protrude from the side surface 12 b in the longitudinal direction of the middle stage wood body 12. With this configuration, when the side surface 12b of the middle board wood body 12 is disposed so as to face the side surface 11b of the lower board wood body 11, the slider body 121c of the first slider 121 is engaged with the first rail 111. Can do.

  For example, the second slider 122 is connected to the lower surface of the middle board wood body 12 and is configured by a plate member protruding at least on both sides in the lateral direction. The protruding portion of the plate member constitutes the second slider 122 and is inserted into the gap between the second rail 112 formed on the lower board wood body 11 and the upper surface 11c. Further, the positional relationship between the first slider 121, the second slider 122, and the stopper 113 is such that the slider body 121c of the first slider 121 is raised along the first rail 111 and brought into contact with the stopper 113. The slider 122 is configured to be disposed at a position where it can be inserted into the gap between the second rail 112 and the upper surface 11c.

  The middle board wood body 12 is also a board body arranged below the upper board wood body 13. Therefore, the middle board wood body 12 has a pair of first rails 123 and 123 arranged in the height direction along the side surface 12c so that the upper board wood body 13 can slide along the side surface 12c and the upper surface 12d. A pair of second rails 124, 124 arranged in a direction intersecting the center line of the ship along the upper surface 12 d, and the upper board wood body 13 slid along the first rail 123 along the second rail 124 And a stopper 125 that is stopped to be slidable.

  The first rail 123 is made of a steel material combined in a T-shaped cross section. Such steel material is fixed to the middle-stage base wood 12 by welding with a T-shaped leg portion disposed along the height direction of the side surface 12c. With this configuration, a gap can be formed between the T-shaped face material of the steel material and the side surface 12c, and a part of the upper board wood body 13 can be inserted along the face material of the steel material.

  The second rail 124 is made of a steel material having an L-shaped cross section like the second rail 112 of the lower board wood body 11, and the middle board wood body 12 is the same as the second rail 112 of the lower board wood body 11. Is fixed to the upper surface 12d. However, the second rail 124 is disposed so as to protrude toward the side surface 12c on which the first rail 123 is disposed. A portion from which the first rail 123 protrudes constitutes a stopper 125. The stopper 125 can come into contact with a part of the upper board wood body 13 raised along the first rail 123 to stop the upper board wood body 13 from rising. Further, a plurality of set bolts 126 are arranged along the longitudinal direction on the second rail 124 so that a part of the inserted upper board wood 13 can be fixed. In addition, the notch part 124a formed in the 2nd rail 124 is an opening part used when conveying the intermediate | middle board | substrate board 12 with a crane.

  Further, the middle board wood body 12 maintains a fixed state in the water before entering the ship, and when loading on the lower board wood body 11, the diver needs to be easily lifted in the water. Is configured to be adjustable. Specifically, the middle board wood body 12 has a box shape formed of a steel plate so as to have a sealed hollow portion. Therefore, the middle board wood body 12 is formed in a structure that generates buoyancy by the air stored in the hollow portion. Further, a plurality of weight pockets 127 are arranged on the side surface 12a of the middle board wood body 12, and the buoyancy of the middle board wood body 12 can be suppressed by arranging a predetermined weight in the weight pocket 127. It is configured to be able to. That is, when it is desired to maintain the state of being placed on the bottom, a predetermined weight is placed in the weight pocket 127, and when it is desired to load the middle board wood body 12 on the lower board wood body 11, the weight is removed. The middle board wood body 12 is raised using buoyancy. Since the middle board wood body 12 is moved in a state where the upper board wood body 13 is loaded, the buoyancy generated in the middle board wood body 12 is based on the total weight of the middle board wood body 12 and the upper board wood body 13. The volume of the hollow portion is designed so as to provide an appropriate weight balance that can be moved in water. The overhanging portion of the weight pocket 127 also has a function for a diver to lift the middle board wood body 12 underwater or to carry the middle board wood body 12 with a crane or the like.

  The upper board wood body 13 is a board body arranged at the uppermost stage of the abdominal board wood 1. Accordingly, the upper board wood body 13 has an inclined surface 13a that comes into contact with the ship bottom, and is composed of timber such as rice pine formed in a wedge shape as a whole so as not to damage the ship body.

  In addition, the upper board wood body 13 is configured to be slidable along the side surface 12c and the upper surface 12d of the middle board wood body 12 one step below. Specifically, a pair of first sliders 131 and 131 slidably disposed along a first rail 123 disposed on the middle board wood 12 and a second rail 124 disposed on the middle board wood 12. And a pair of second sliders 132, 132 slidably arranged along.

  The first slider 131 and the second slider 132 are, for example, formed by plate members that are connected to the lower surface of the upper board wood body 13 and protrude on both sides in the lateral direction and the longitudinal direction. Specifically, a T-shaped notch that can be inserted into the first rail 123 of the middle board wood body 12 is formed at the tip of the plate member protruding to the side surface 12c side of the middle board wood body 12, The notch constitutes the first slider 131. Further, the projecting portion in the short direction of the plate member constitutes the second slider 132, and is inserted into the gap between the second rail 124 formed on the middle board wood body 12 and the upper surface 12d. The positional relationship among the first slider 131, the second slider 132, the first rail 123, and the stopper 125 is raised by inserting the notch portion of the first slider 131 into the first rail 123, and the first slider 131 is moved to the stopper 125. The first slider 131 is separated from the first rail 123 while being in contact with the first slider 123, and the second slider 132 is arranged at a position where it can be inserted into the gap between the second rail 124 and the upper surface 12d.

  Further, as described above, the upper board wood body 13 has a large ratio of timber and has a structure in which buoyancy is likely to occur. Therefore, before entering the ship, it is necessary to maintain a fixed state in water, and a weight pocket 133 is arranged on the side surface of the upper board wood body 13 in order to adjust the buoyancy. By arranging a predetermined weight in the weight pocket 133, the buoyancy of the upper board wood 13 can be suppressed. That is, when it is desired to maintain the state of being placed on the bottom, a predetermined weight is placed in the weight pocket 133, and when the upper board wood 13 is to be loaded on the middle board wood 12, the weight is removed. The upper board wood 13 is raised using buoyancy. Note that the L-shaped members arranged on both sides of the upper board wood body 13 are overhanging portions 134 for the diver to lift the upper board wood body 13 in water.

  Here, FIG. 4 is a diagram showing the positional relationship between the wood plank and the ship bottom at the time of dredging. As shown in the figure, the lower board wood body 11, the middle board wood body 12 and the upper board wood body 13 constituting the abdominal board wood 1 of the present invention are substantially perpendicular to the center line of the ship on the bottom 2 of the ship. Are arranged in a line in the direction (longitudinal direction of the abdominal board 1), the lower board wood body 11 is arranged at position α, the middle board wood body 12 is arranged at position β, and the upper board wood body 13 is arranged at position γ. And Further, a propeller 31, a bilge keel 32, and other projections are arranged on the bottom 3 of the vessel that enters the vessel. When the vessel enters the vessel, the propeller 31 passes near the position α, and the bilge keel 32 passes near the position β. Shall.

  Now, the height of the lower board wood body 11 is h1, the height of the middle board wood body 12 is h2, the height of the upper board wood body 13 is h3, the distance between the propeller 31 and the base 2 is D1, and the bilge keel 32. And D2 and the distance between the bottom 3 and the bottom 2 at the position α is D3. In the present invention, the height h1 of each of the wooden bodies 11 to 13 satisfies the relationship of height h1 <distance D1, height h2 <distance D2, and (height h1 + height h2 + height h3) ≦ distance D3. ~ H3 is set. That is, each board body 11 to 13 is formed at heights h1 to h3 that do not come into contact with the bottom 3 and the protrusions from the bottom 3 (for example, the propeller 31, the bilge keel 32, the barbus / bow, etc.) when the ship enters. . In this way, by setting the heights h1 to h3 of the wood blocks 11 to 13 and forming the abdominal wood 1 in multiple stages, by placing the wood blocks 11 to 13 on the bottom 2 individually, 3 is a case in which a projecting object is present in 3, the ship can be crushed without coming into contact with the board bodies 11 to 13 and the ship bottom 3 or the projecting object, and the size of the abdominal board 1 can be increased. be able to.

  Finally, a method for supporting a ship according to the present invention will be described. Here, FIG. 7 is a figure which shows the support method of the ship which concerns on this invention, (A) is an arrangement | positioning process, (B) is an approach process, (C) is a drainage process and a bottoming process, (D) is The adjustment process, (E) shows the support state. In addition, in each figure, about the same components as 1st embodiment described in FIG. 1 etc., the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  The ship support method according to the present invention shown in FIGS. 7 (A) to 7 (E) is a support method for the ship 6 in which the ship 6 is supported by the main board 5 and the abdominal board 1. Arrangement process of placing the tree 5 and the abdominal board 1 on the bottom 2, an entry process for entering the ship 6 into the dock, a draining process for discharging the water in the dock, and the ship 6 on the main board 5 A bottoming step for bottoming, and an adjusting step for placing the abdominal board 1 to the bottom 3 of the ship 6. A wooden body 11, a middle board wooden body 12, and an upper board wooden body 13). In the placement process, each wood board body 11-13 is individually arranged on the bottom 2 and in the adjustment process, each wood board body 11-11. 13 is characterized in that it is stacked in order from the top and assembled to the abdominal board 1.

  The arrangement process shown in FIG. 7A is a process of arranging the main board 5 and the abdominal board 1 in the dock. The arrangement positions of the main board 5 and the abdominal board 1 are planned in advance according to the type, size, etc. of the vessel 6 scheduled to be docked. For example, the main board 5 is arranged along the center line of the ship 6. Further, the abdominal board 1 is in a direction substantially perpendicular to the center line of the ship 6, and the lower board wood body 11, the middle board wood body 12, and the upper board wood body 13 are in the lower stage in a direction away from the center line of the ship 6. Are arranged in a row in order. At this time, the position of the lower board wood body 11 corresponds to the arrangement position of the abdominal board wood 1. Further, in the middle board wood body 12 and the upper board wood body 13, the first slider 121 of the middle board wood body 12 is engaged with the first rail 111 of the lower board wood body 11, and the first slider of the upper board wood body 13. 131 is arrange | positioned so that it may engage with the 1st rail 123 of the middle stage board | substrate body 12 (refer FIG. 5). In addition, the arrangement direction of each board body 11 to 13 is determined by the position at which the abdominal board 1 is arranged, the shape of the ship bottom 3, and the like, and may be a direction substantially parallel to the center line of the ship 6. It may be a direction that intersects the center line of the ship 6.

  The approach process shown in FIG. 7B is a process for causing the ship 6 to enter the dock. The ship 6 is arranged on the main board 5 and the abdominal board 1 by this approach process. At this time, the abdominal board 1 is divided into the respective board bodies 11 to 13 and arranged on the bottom 2 so that the height is lowered. Therefore, even if the ship 6 has a protrusion such as a propeller or a bilge keel that protrudes from the ship bottom 3 and the abdominal tree 1 is disposed on the path of the protrusion, the protrusion contacts the abdominal tree 1. The draft W at the time of dredging can be set deeper than before.

  The draining process and the loading process shown in FIG. 7C are processes in which the ship 6 is brought close to the bottom 2 by discharging water from the dock to the outside, and the ship 6 is settled on the main board 5. . If the water in the dock is completely drained as it is, the ship 6 becomes unstable, so that the ship bottom 3 is supported by the abdominal tree 1 by the adjustment process described later, and the ship 6 is stabilized. In addition, the water in the dock is often cloudy and the visibility is poor. If the abdominal board 1 of the present invention is used, the upper board board 13 and the middle board board 12 are levitated along predetermined rails. The abdominal tree 1 can be easily assembled.

  7D, the lower board wood body 11, the middle board wood body 12, and the upper board wood body 13 are loaded to assemble the abdominal board 1, and the abdominal board 1 is attached to the bottom 3 of the ship 6. This is the process of addressing. Specifically, the abdominal tree 1 is assembled by stacking the respective wooden bodies 11 to 13 by the assembling method of the abdominal tree 1 shown in FIG. By using the abdominal tree 1 of the present invention, the abdominal tree 1 can be easily assembled, the burden on the diver can be effectively reduced, and the working time can be shortened. In addition, since the driving force of a hydraulic cylinder or the like is not used, the energy efficiency is excellent, and it is possible to easily cope with the enlargement of the abdominal board 1. In order to bring the upper board wood 13 into contact with the ship bottom 3, the upper board wood 13 and the middle board wood 12 are slid on the middle board wood 12 and the upper board wood 13 and the middle board wood 12 are moved to the lower board wood. Processing such as sliding on the body 11, sliding the abdomen wood 1 on the bottom 2, and driving a wedge into the upper board wood 13 may be performed.

  The support state shown in FIG. 7E is a state in which the water in the dock is completely drained. The ship 6 is supported in a stable state by the main board 5 and the abdominal board 1 arranged on both sides thereof (only one side is shown in the figure), so that desired maintenance can be performed safely. it can.

  When the ship 6 is put out, (1) water is put in the dock so that the ship 6 is lifted from the main board 5 and the abdominal board 1 and the abdominal board 1 is again connected to each board body 11 to 11. The ship 6 may be moved after being divided into 13 and arranged on a plane, or (2) even if the ship 6 is moved in a state where the abdominal board 1 is assembled, the projecting object does not come into contact. You may make it move the ship 6 after filling water in a dock or making the ship 6 light.

  The present invention is not limited to the above-described embodiment. For example, the structure of the rail, the slider, and the stopper is not limited to that shown in the drawings, and various modifications can be made without departing from the spirit of the present invention. is there.
