Description

  The present invention relates to a crane device mounted on a ship, and more particularly to a hull retractable cargo handling and transportation device that is installed integrally on a side port door.

As a conventional ship crane apparatus, for example, as shown in Patent Document 1, there is one in which a crane is installed on a ship deck. Therefore, it is installed at a specific place on the ship because it becomes a traffic obstacle, and the installation place is generally not a windtight or watertight compartment.
Patent Document 2 can be cited as an example of installing a crane in an opening provided on a shore side portion, which lifts and collects a boat. This boat raising apparatus has a configuration in which a swing crane is installed on a ceiling in an opening in which the heel side is in an open state, and no door is provided.

JP-A-7-300292 JP 2006-1442 A

In the crane apparatus shown in Patent Document 2, since a swivel crane is installed on the ceiling in the opening portion (hereinafter also referred to as a side port) that remains open, the rain and rain is the same as that installed on the exposed deck. The opening is not a windtight or watertight compartment. For these reasons, the conventional ship crane apparatus has the following problems.
(1) The required boom length is increased for the required outreach. As a result, the crane apparatus becomes larger.
(2) Since the crane device is directly exposed to seawater splashes, wind and rain, sand dust, ultraviolet rays, etc., the deterioration progresses, and maintenance and labor are required.
(3) The stability and design of the ship will deteriorate.
(4) When installing the machine structure and equipment of the crane device on the deck or ceiling in the side port, the installation location must be installed in a location that does not affect the construction of the insulation on the back side. The heat insulating material construction process has become complicated, leading to an increase in cost.
(5) If the side port is left open, measures against illegal intruders must be taken.
(6) Radio stealth is reduced in ships.

  The present invention has been made in view of the above problems, and is a hull retractable cargo handling device that can be installed on a side port door that can be configured in a wind-tight or water-tight compartment, and can lift and lower suspended loads. The purpose is to provide.

  In order to solve the above-mentioned problems, a hull retractable cargo handling and transporting apparatus according to the present invention includes a cargo storage compartment defined in a hull portion of the hull, and an upper end portion, a front end portion or a rear end portion at an opening portion of the cargo storage compartment. A door having an end portion that is openably and closably connected via a hinge portion, and a crane that is installed on an inner surface of the door and lifts or lowers a cargo.

  In the present invention, the cargo handling apparatus can be stored in the hull by installing a crane on the inner surface of the side port door. Moreover, the crane can be put into a swinging-out state by fully opening a side port door at the time of use. Therefore, in the cargo handling and conveying apparatus of the present invention, the crane is offset by the distance from the outer wall surface of the cargo storage section to the installation position of the crane and is attached to the inner surface of the door, so that the outreach of the crane becomes longer. Therefore, since the boom length can be shortened by the offset distance, the crane can be miniaturized. In addition, since the door is closed when not in use, it is not directly exposed to splashes of seawater, wind and rain, ultraviolet rays, dust, etc., so that the deterioration is unlikely to occur, which contributes to reduction in maintenance work and costs. In addition, the cargo handling and conveying apparatus of the present invention can be constructed irrespective of the heat insulating material construction process on the back side of the wall surface of the cargo storage section. In addition, the design is improved, and it is advantageous for measures against illegal intruders.

  Since the crane is configured to include a swivel and telescopic boom, the outreach of the crane becomes longer, which is advantageous for loading and unloading cargo. On the contrary, since the number of expansion / contraction steps of the crane can be reduced by the distance of the offset, the construction of the crane is simplified, the size can be reduced, and the production cost is reduced.

The door is substantially flush with the side wall when closed, and the cargo storage compartment has a weather-tight or water-tight structure.
With this configuration, the cargo storage compartment can be a wind-tight compartment or a water-tight compartment, and when it is a water-tight compartment, the stability of the ship is improved. Moreover, in a ship, radio stealth can be maintained.

The crane may have a pair of pulleys that guide a winch wire at a distal end thereof, and may include a boom attached to the door and a winch device attached to the door.
With this configuration, when the door is fully opened, the crane can be put out by a boom having a certain length, and the crane can be made small and small.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
1 to 3 show a first embodiment of the present invention, and FIG. 1 is a schematic sectional view showing a storage state of a hull retractable cargo handling device according to the first embodiment. It is sectional drawing when seeing. FIG. 2 is a schematic cross-sectional view showing a crane swinging state when the door of FIG. 1 is fully opened, and FIG. 3 is an explanatory view showing a cargo handling work state.

  This hull retractable cargo handling and transporting device 10 uses a swiveling and telescopic deck crane 4 installed on the inner surface of a door (also referred to as a side port door) 3 with a cargo receiving section 2 formed on the side 1 of the hull. Thus, the cargo 5 is lifted and stored in the cargo storage section 2 from the outside of the ship, or the cargo 5 is unloaded from the ship. Moreover, although this cargo handling and conveying apparatus 10 is a case where it is equipped with a port, it can also be equipped with a starboard, and is equipped with either one or both of a port and starboard. It can also be equipped at the stern end. Therefore, although the example which provided the cargo storage area 2 in the part of the shore side 1 is shown here, it can be provided in the arbitrary positions of the outer fence part of a ship.

  The cargo storage section 2 is not particularly limited, but is a section formed by a ceiling 6 made of an upper deck, a floor or passage 7 made of a lower deck, and a side wall 8. A work stage part for cargo handling work may be provided on the floor or the passage 7 part. The door 3 is coupled to the mounting member 12 of the ceiling 6 via a hinge 11 at the upper end so as to open and close the opening of the cargo storage compartment 2.

  As an opening / closing means for the door 3, a hydraulic cylinder 13 is pivotally attached to the mounting member 12 of the door 3 and the ceiling 6 so that both ends (each end of the cylinder case and the rod) can rotate about the shaft. The door 3 is a single-opening type in which the lower side opens upward, and rotates about 90 degrees in the clockwise direction. Note that one end of the hydraulic cylinder 13 can be attached to the ceiling 6 without the attachment member 12 interposed. Further, instead of the hydraulic cylinder 13, a mechanism that opens and closes the door 3 by a rotation method using the hinge portion 11 as a torque actuator or other mechanisms may be used.

  When the door 3 is closed, the door 3 has substantially the same inclination angle or substantially the same plane as the heel side 1. That is, it is configured to be substantially flush with the side wall or stern wall of the hull. Further, a seal member 14 such as a rubber packing is attached to the inner surface of the door 3 so as to be watertight when closed, and the seal member 14 is in contact with an edge plate 15 provided around the opening so as to be sealed. It has become. The seal structure of the door 3 may be a metal touch. Further, the door 3 has, for example, a wind-tight structure or a water-tight structure according to the section requirements of the cargo storage section 2.

  On the inner surface of the door 3, a swiveling and telescopic deck crane 4 for lifting or lowering the cargo 5 is installed. The swivel and telescopic deck crane 4 is a well-known one, and the detailed structure and illustration thereof are omitted here. However, the boom 16 can be swiveled 360 degrees with respect to the support column 17 and can extend and retract over a plurality of stages. It is configured to be possible. Further, the deck crane 4 is installed so that the turning center of the boom 16 is located at the inner surface position of the door 3 that is separated from the outer wall surface of the cargo storage section 2 by a distance L (offset distance).

Since the cargo handling apparatus 10 of the present embodiment is configured as described above, in the storage state of FIG. 1, the deck crane 4 is stored in a state in which the boom 16 is contracted and stood upward, As shown in FIG. 2, the door 3 is opened almost horizontally upward by the operation of the hydraulic cylinder 13 as shown in FIG. As a result, the deck crane 4 is in the swing-out state as shown in FIG. It becomes longer by the distance L from the outer wall surface. Therefore, the cargo 5 can be carried in and out far away, and can be carried in and out without causing the suspended load to collide with the hull of the ship even if the hull is slightly laterally shaken.
Conversely, since the number of expansion / contraction steps of the boom 16 can be reduced by an amount corresponding to the offset distance L, that is, the length of the boom 16 can be shortened, the configuration of the deck crane 4 can be simplified and the size can be reduced. , Production costs are lower.

The hull retractable cargo handling and transporting apparatus 10 of the present embodiment is provided with a swivel and telescopic deck crane 4 on the inner surface of a door 3 that can be opened and closed in a cargo storage section 2 provided on the side 1 side. Therefore, in addition to the above effects, there are the following effects.
(1) The cargo storage compartment can be, for example, a wind-tight compartment or a water-tight compartment. When the cargo compartment is made watertight, the stability of the ship is improved.
(2) Since the cargo handling equipment is housed in the ship, there is little deterioration of parts and oils and fats due to ultraviolet rays, seawater splashes, wind and rain, and dust. Therefore, it contributes to the reduction of maintenance costs including life cycle costs.
(3) Since there is no need to install a crane on the hull deck as in the prior art, the crane installation process is flexible. Processes convenient for the door and the cargo handling / transporting device can be assembled, resulting in cost reduction.
(4) Since the appearance can be made clean, the design of the ship is improved.
(5) The ship can maintain radio stealth.
