BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoist having a cargo port on a side wall of a ship and carrying a cargo in a cargo hold of a hull when carrying a cargo work by berthing. The present invention relates to a cargo handling device for ships and a construction method thereof.

[0002]

2. Description of the Related Art For example, a ship in which a cargo hold is formed on a deck of a car carrier or the like, a cargo handling port is provided on a side wall of a hull, and a hoist provided in the cargo hold from the cargo handling port performs cargo handling with a quay. There is. FIG. 3 shows a conventional cargo handling device for the ship. First, the configuration of the conventional cargo handling device will be described.

Reference numeral 1 is a quay, 2 is a hull, 3 is a cargo hold, and 4 is a deck of the cargo hold 3. Reference numeral 5 is a cargo handling port opened on the side wall of the hull 2, and 6 is a cargo handling port door supported on the side wall of the hull 2 by a hydraulic link type opening / closing means (not shown), which is moved upward when opened. 7 is a trolley hoist installed above the cargo hold 3. A guide rail 8 mounted on the ceiling of the cargo hold 3 suspends a trolley rail 9 so that the trolley rail 9 can travel freely. Is suspended in.

Therefore, at the time of loading and unloading, the loading port door 6 is opened (the state shown in the drawing), and the trolley rail 9 and the guide rail 8
The trolley hoist 7 can be loaded and unloaded between the cargo hold 3 and the quay 1 by extending the trolley hoist 7 to the upper side of the quay 1 along the line. The second layer and the third layer 4'in the figure
Is an overhanging deck that is used only when loading and unloading the floor, and has a rotating or sliding structure. Further, 10 is a cargo handling cage.

In this structure, when the cargo handling door 6 is closed, the trolley rail 9 must be stowed rearward, and the storage space S for the trolley rail 9 must be secured. The storage space for cargo hold 3 will be reduced accordingly. For example, in the case of a car carrier, cars will be loaded on the outward route and other cargo will be loaded on the return route.
The height between the decks of each floor is set according to the height of the automobile. Therefore, the automobile cannot be loaded in the place where the storage space S is formed.

Further, since the guide rail 8 is interposed,
The height of the guide rail 8 and the relationship of the trolley rails 9 affect the trolley hoist 7, which lowers the lift.
In particular, the deck 4 on the third layer (uppermost floor) of the cargo hold 3 has a disadvantage that the work space is lowered and the work safety is impaired. A forklift or the like is used for loading and unloading in the cargo hold 3 and the quay 1.

Further, since the trolley rail 9 is used in a cantilevered state, the structure of the trolley rail 9 and the mounting of the guide rail 8 must be made sufficiently strong. Further, when carrying out the cargo handling work, first, the cargo handling door 6 is opened, and after the cargo handling door 6 is completely opened, the trolley rail 9 is extended and the trolley hoist 7 is moved to a predetermined position to start the hoisting work. Therefore, it took a long time to start the hoist work.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a cargo handling apparatus according to the present invention, and FIG. 2 is a process diagram showing a method for constructing the cargo handling apparatus. The same parts as those of the conventional configuration shown in FIG. 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

Reference numeral 11 denotes a cargo door which is hinged to the side wall of the hull and is opened and closed by a hydraulic opening / closing mechanism (not shown). 12 and 13 are trolley rails,
Is a rail with hull fixed to the ceiling inside the cargo hold,
Reference numeral 13 is a rail with a door fixed to the inner surface of the cargo door 11. When the cargo door 11 is opened, the door-mounted rail 13 is in a horizontal state, overhangs above the quay 1, and is linearly connected to the hull-mounted rail 12.

Therefore, when the cargo door 11 is opened, the hull-equipped rail 12 and the door-equipped rail 13 are connected, and the trolley hoist 7 can move back and forth between the hull-equipped rail 12 and the door-equipped rail 13. Cargo handling can be performed between the cargo hold 3 and the quay 1. When the loading door 11 is closed, the rails 13 with doors are oriented vertically, and the rails 1 with hull
The relationship with 2 is broken. Of course, at this time, the trolley hoist 7 is housed and locked on the side of the rail 12 with the hull.

The hull-equipped rails 12 and the door-equipped rails 13 may be rails having a length corresponding to a range in which the trolley hoist 7 travels to carry cargo between the cargo hold 3 and the quay 1. Moreover, since the rail 12 with the hull and the rail 13 with the door are directly fixed to the hull 2 and the loading / unloading door 11,
Rail rigidity is increased and trolley hoist 7
Raises the head. That is, the height of the work space of the uppermost floor of the cargo hold 3 can be increased by several tens of cm.

By the way, in order to construct this cargo handling device,
If this is constructed after the construction of the hull, it will be a considerably large-scale construction, and there is a drawback that the mounting accuracy is difficult to obtain. For example, the rail 12 with the hull is attached to the ceiling portion of the cargo hold 3, and the rail 13 with the door must be attached while the rail 13 with the door is aligned with the rail 12 with the hull with the cargo door 11 opened.

Further, the rail 12 with the hull and the rail 1 with the door
After the 3 is attached, the trolley hoist 7 will be installed. The rail 12 with the hull, the rail 13 with the door, and the trolley hoist 7 are installed.
All the work such as installation of the above is upward work, and it is dangerous work to handle heavy objects.

On the other hand, the rail 13 with the door is used as the cargo door 11
, And the trolley hoist 7 is temporarily assembled to the rail 12 with the hull, and after these are mounted on the block, the cargo door 11 is opened and the rail 12 with the hull is adjusted according to the rail 13 with the door. However, even if the trolley hoist 7 is installed, the adjustment becomes unstable, and it is difficult to secure delicate precision. Moreover, since the work involves hanging heavy objects, there remains a problem in work safety.

Therefore, according to the present invention, the cargo handling apparatus is constructed on the ground by accurately incorporating it into the mounting block. The construction method of the cargo handling apparatus according to the present invention will be described below with reference to FIG. First, a rail 13 with a door is attached to and integrated with the cargo door 11 at the factory. In addition, the trolley hoist 7 is temporarily assembled on the rail 12 with the hull after ensuring the accuracy. Assembled state, FIG. 2 (A).

Next, in order to temporarily and securely mount the trolley hoist 7 and secure it, the ceiling portion of the cargo hold after completion is placed in the opposite direction, and the trolley hoist 7 together with the hull rails 12 are placed there. Temporarily mount and tie it up to assemble the medium block X. The state of middle assembly, FIG. 2 (B). Based on the middle-assembled block X, the mounting block Y is assembled by attaching the outer plate portion which is the frame of the cargo handling door 11 and the deck portion of the cargo hold.

In a state in which the mounting block Y is laid down sideways, the cargo handling door 11 having the rails 13 with doors attached is brought into contact with the cargo handling door 5 and hinged to be attached. After the loading port door 11 is attached, the loading port door 11 is once opened by a crane at the shipyard and is held at right angles to the mounting block Y. FIG. 2C.

In this state, the sub-assembled hull-equipped rails 12 and trolley hoist 7 are pulled up to ensure the accuracy of the door-equipped rails 13 and the hull-equipped rails 12 as the rails pass each other, and the hulls are set at predetermined positions. The attached rail 12 is fixed to the ceiling by welding. FIG. 2C. Then, after fixing the trolley hoist 7, the loading port door 11 is closed by the crane at the shipyard to complete the mounting block Y. Figure 2
(D).

The mounting block Y completed in this way
Is, with the ceiling part facing up and the cargo handling port 5 on the outside,
It will be mounted on the hull according to the construction process of the ship. As described above, the work of assembling the mounting block Y is done on the ground and is a downward work, so that safe work can be secured and the construction accuracy of the cargo handling device can be secured by ground work.

INDUSTRIAL APPLICABILITY According to the present invention, the cargo door provided on the side wall of the hull is a hinged rotary opening / closing type, and the trolley rail for suspending and holding the trolley hoist is fixed to the ceiling of the cargo hold. And a rail with a door fixed to the inner surface of the door, and when the door is opened, the rail with the door is connected to the rail with the hull in a horizontal straight line.

As a result, it is not necessary to form the trolley rail storage chamber, and the cargo storage space can be expanded.
Since the trolley rail is attached directly to the hull and door, the rigidity of the rail can be increased and the height of the working space can be increased. When the door is opened, the trolley hoist can run, and the start time of hoist work can be shortened.

Further, in the construction of this cargo handling apparatus, since it is assembled in a small size and assembled in the process of manufacturing the medium block and the mounting block, the accuracy is ensured on the ground and all the downward work. It is possible to deal with, and work safety can be secured.
