  In such a ship equipped with a loaded boat, an opening is provided in order to provide an accommodation recess on the shore side. However, if the opening is left open, seawater will enter and the floor will slip easily. Therefore, it is inconvenient to lift and unload the onboard boat, and a door may be provided to impair the beauty of the ship.

  The opening of the storage recess on the shore side is about 10 tens m or less in terms of width in terms of accommodating the mounted boat, and when the door is made of steel plate, it is difficult to open and close manually. It is necessary to install a drive source that opens and closes the door.

  Also in the boat raising device, a drive source for driving David and the boom is necessary, and two kinds of drive sources for the boat raising device and the door are required in one accommodation recess.

  On the other hand, in recent ships, space saving is demanded. However, if two drive sources are installed as described above, there is a limit to miniaturization of the housing recess, and the door and the boat raising device are installed. There is a problem that the cost of the entire equipment installed in the containing recesses is also increased.

  Therefore, the present invention was devised to improve the above-mentioned problems, and the object of the present invention is to reduce the cost while improving the aesthetics of the ship and the workability of lifting and unloading the mounted boat. It is an object of the present invention to provide a boat raising device capable of downsizing a recess.

To solve the above object, problem solving means in the present invention down fried the boat against accommodating recess which is provided on the broadside of the hull of the ship to accommodate the tower Notei mounted in the ship in Agetei device, stretching for the boat which suspended via a wire rope is moved by a drive source in the horizontal direction with respect to the housing recess is unloaded the boat to carry and the accommodation recess outside in the housing recess A boom of a mold, a winch capable of extending and winding a wire rope, and an opening of the accommodation recess on the heel side, and the opening of the accommodation recess on the heel side when the opening of the accommodation recess is closed with a single door as a peripheral flush, the outer peripheral contour of the door is formed the same as the contour of the frame of the opening of the accommodating recess, above the boom The door is held and the door is detached and opened from the opening of the accommodation recess when the mounted boat is carried out, and the opening of the accommodation recess is closed by the door when the loading boat is carried in. And

  According to the boat raising apparatus of the present invention, since the door can be driven by the drive source that drives the boom, the cost can be reduced and the housing recess can be downsized. In addition, since the door can close the opening of the storage recess on the shore side, when the mounted boat is not used, it is only necessary to close the opening and open the opening only when necessary. Therefore, it is possible to solve the problem that the floor of the containment recess gets wet with seawater and the like, making it difficult to lift and lower the mounted boat. As well as improving the aesthetics, the problem of corner reflectors can be solved and the radar reflection cross-sectional area can be reduced.

  Hereinafter, as shown in FIG. 1 to FIG. 3, the boat raising apparatus 1 of the present invention is installed in a housing recess R for housing a mounted boat 3 that is provided on the side 2 of the hull S of the ship and is mounted on the ship. And a boom 4 for moving the mounted boat 3 suspended through the wire rope W in the horizontal direction with respect to the housing recess R to carry the loaded boat 3 into and out of the housing recess R. , A winch 5 capable of feeding and winding the wire rope W, and a door 7 for opening and closing the opening 6 of the housing recess R on the heel side 2, and the boom 4 and winch 5 are driven to accommodate the housing recess. The mounted boat 3 can be lowered to the sea surface with respect to R and landed, and conversely, the mounted boat 3 that has landed on the sea surface can be accommodated in the accommodating recess R. .

  Hereinafter, each part will be described in detail. The accommodation recess R is a storage chamber for storing a mounted boat 3 provided in the hull S and provided with a rectangular opening on the side 2 which is the side surface of the hull S of the ship.

  The accommodation recess R includes a floor 10, a side wall 11 along the front-rear direction of the ship, and a ceiling 12, and a mounting table 9 on which the mounted boat 3 is mounted is installed on the floor 10. Moreover, the opening edge 6a in the opening part 6 of the accommodation recess R is depressed toward the accommodation recess R, and the seal member 8 is mounted over the entire circumference of the opening edge 6a. The seal member 8 only needs to be suitable for sealing, and is formed of rubber or the like, for example.

  An extendable boom 4 is attached to the ceiling 12 of the housing recess R. The boom 4 may be fixed to the side wall 11 of the accommodation recess R instead of the ceiling 12.

  The boom 4 includes a slider 14 that holds a winch 5 that can feed and wind up the wire rope W, a slider 14 that holds the slider 14 slidable in a horizontal and horizontal direction with respect to the longitudinal direction of the ship, a guide rail 15, a guide A motor 16 as a drive source capable of driving the slider 14 in the above direction with respect to the rail 15 is provided.

  As shown in FIGS. 1 to 4, the guide rail 15 holds a pair of C-shaped channel-shaped rails 15a and 15b facing each other with the concave portions facing each other, and the rails 15a and 15b, and these rails 15a and 15b. Is provided with a plurality of support members 15c, 15d, and 15e that fix the housing 15 to the ceiling 12 of the housing recess R, and a roller chain 15f that is secured to the lower end of the rail 15a.

  The slider 14 includes a square pipe-shaped slider main body 14a inserted between the rails 15a and 15b, and four wheels that are rotatably supported on the sides of the slider main body 14 and can travel in the recesses of the rails 15a and 15b. 14b, and a winch 5 and a motor 16 are fixed below the slider body 14a.

  Therefore, the slider 14 is guided by the rails 15a and 15b of the guide rail 15 so that the slider 14 can smoothly move in the horizontal and horizontal directions with respect to the longitudinal direction of the ship which is the longitudinal direction of the rails 15a and 15b. It has become.

  The winch 5 can feed out and wind up the wire rope W, and can move the mounted boat 3 in the vertical direction. When the distance between the mounted boat 3 and the slider 14 is short and the winch 5 interferes, a sheave is provided at the lower end of the slider 14 so that the winch 5 is provided at a position that does not interfere with the mounted boat 3. May be.

  A sprocket 17 is attached to the shaft of the motor 16. The sprocket 17 meshes with the roller chain 15 f of the guide rail 15, and the slider 16 is moved with respect to the guide rail 15 by driving the motor 16. 1. Move the mounted boat 3 from the storage position of FIG. 1 where the mounted boat 3 is placed directly above the mounting table 9 and carry the mounted boat 3 out of the storage recess R and reciprocate to the lifting and lowering position of FIG. Be able to. That is, the boom 4 can be expanded and contracted by moving the slider 14 with respect to the guide rail 15 as described above.

  Therefore, in order to allow the mounted boat 3 to land on the sea surface from the mounting table 9, the mounting boat 3 mounted on the mounting table 9 is lifted from the mounting table 9 by slightly winding the wire rope W with the winch 5, and then the slider 14. It is only necessary to place the mounted boat 3 above the sea surface by moving it in the direction in which it protrudes from the guide rail 15, that is, in the direction to exit outward from the receiving recess R, and drive the winch 5 to unwind the wire rope W. By doing so, the mounted boat 3 can be lowered and landed on the sea surface. On the other hand, in order to place the mounted boat 3 on the sea surface on the mounting table 9, the slider 14 is moved to the lifting / lowering position that protrudes outward from the housing recess R, and the wire rope W is unwound to unload the mounted boat 3. After suspending with a hook (not shown) provided at the tip of the wire rope W, the wire rope W is wound up by the winch 5 to release the mounted boat 3 and lift it to a height slightly above the mounting table 9. Then, the slider 14 is driven to the accommodation position, the mounted boat 3 is moved above the mounting table 9, and the winch 5 is driven again to lower the mounted boat 3 to be mounted on the mounting table 9. .

Subsequently, as shown in FIG. 3, the outer periphery of the door 7 has the same shape as the outline of the frame of the opening 6 and is fixed to the tip of the slider 14. The door 7 can open and close the opening 6 of the housing recess R on the heel side 2 and closes the opening 6 of the housing recess R when the opening 6 of the housing recess R is closed. ing. As shown in FIG. 1, when the door 7 closes the opening 6 of the housing recess R, the edge of the surface of the door 7 on the housing recess R side is attached to the seal member 8 attached to the opening edge 6 a of the opening 6. Adhering closely, it is possible to prevent intrusion of seawater, rainwater, etc. into the accommodation recess R.

  The door 7 is driven by the motor 16 together with the slider 14. Specifically, when the slider 14 is in the housing position for housing the mounted boat 3, the door 7 closes the opening 6 of the housing recess R, and the slider 14 lifts and lowers the mounted boat 3 to lift and lower it. When moving to the position, the door 7 moves together with the slider 14 in the horizontal direction away from the housing recess R, leaves the opening 6 and opens the opening 6. That is, the door 7 is detached and opened from the opening 6 of the housing recess R when the mounted boat 3 is unloaded from the housing recess R, and the opening 6 of the housing recess R is opened when the loaded boat 3 is carried into the housing recess R. The door 7 can be closed.

  As described above, in the boat raising apparatus 1 according to the present embodiment, the door 7 can be driven by the drive source that drives the boom 4. Therefore, the cost can be reduced and the accommodation recess R can be downsized. . In addition, since the door 7 can close the opening of the accommodation recess R on the heel side 2, when the mounted boat 3 is not used, the opening 6 should be closed only when necessary. Since the intrusion of seawater, rainwater, etc. can be prevented, the problem that the floor 10 of the accommodation recess R gets wet with seawater, etc., makes it difficult to lift and lower the onboard boat 3, and the door 7 is opened. When the portion 6 is closed, it becomes flush with the periphery of the opening 6 on the heel side 2 so that not only the appearance is improved but also the problem of the corner reflector can be solved and the effect of reducing the radar reflection cross section can be expected. .

  Further, the door 7 merely opens and closes the opening 6 of the accommodation recess R, and the door 7 does not need to function as a strength member for supporting a drive source and other members constituting the boat raising apparatus 1. Therefore, the door 7 is light, and the drive source does not increase in output.

  Although the motor 16 is used for driving the boom 4, the motor 16 can use a hydraulic motor in addition to an electric motor, and is a direct acting cylinder device that drives the boom 4 itself with fluid pressure. Also good. Furthermore, although one boom 4 is used in the present embodiment, a plurality of booms 4 may be provided.

  By making the boom 4 extendable and retractable, it is advantageous in that the boom 4 can be installed with the depth of the accommodation recess R. However, the structure of the boom 4 described above is an example, for example, It is also possible to employ the boom 20 having the structure shown in FIG.

  The boom 20 is guided by guide rollers 21 and 22 attached to the ceiling 12 of the housing recess R, and is supported so as to be movable in a horizontal and horizontal direction with respect to the longitudinal direction of the ship. The motor 23 is driven. A winch 24 is fixed to the boom 20, and the mounted boat 3 can be lifted and lowered by the winch 24. The door 7 described above is fixed to the tip of the boom 20. In the structure shown in FIG. 5, the sealing member 25 is mounted on the surface of the door 7 on the side of the housing recess R, instead of providing the sealing member on the opening edge 6 a of the opening 6 of the housing recess R. Intrusion of seawater or the like into the housing recess R is prevented.

  Even if the boom 20 is configured in this manner, the door 7 can be opened and closed by the drive source of the boom 20, so that the same operational effects as described above can be obtained.

 Further, the shapes of the opening 6 and the door 7 are not limited to rectangles, and the shape of the opening 6 of the accommodation recess R and the shape of the door 7 may be matched.

 Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to the details shown or described.

  INDUSTRIAL APPLICABILITY The present invention can be used for a boat raising apparatus that lifts and lowers a loaded boat mounted on a ship.
