The elevating mechanism 32 includes a pair of gate-shaped support members 3 arranged side by side in the bow-stern direction A so as to straddle the opening 30.
3, a plurality of lifting winch devices 35 attached to the support member 33 and wound around a lifting rope 34,
At the time of elevating the elevating base member 31, the elevating base member 31 is vertically erected on a side portion of the elevating base member 31 via a mounting member 36, and is fitted to an elevating guide hole 37 formed in the worktable 8 so as to be able to move up and down.
Elevating guide rod 3 for preventing swing of elevating table member 31
And 8.

In the above configuration, when the transport ship 1 is traveling, the rotating winch device 20 is driven to wind the rotating rope 24, and the connecting path plate 17 is flipped up as shown by the phantom line in FIG. Keep it.

When the vehicle arrives at the destination and arrives at the shore, the rotatable winch device 20 is driven to draw out the rotatable rope 24, and the connecting path plate 17 is rotated around the horizontal shaft member 15 by its weight. It passes to the quay 16 as shown by the solid line in the figure.

By doing so, the quay 16 side and the workbench 8 can be communicated with each other. For example, when loading a load (eg, gravel) N on the transport ship 1, a dump truck on which the load N is placed is used. 6 is moved from the quay 16 to the work table 8 and further above the elevating table member 31 across the connecting path board 17.

Then, the respective lifting winch devices 35 are driven to lower the lifting platform member 31 into the hold 3, dump the loading platform, and load N into the hold 3. At this time, the dump truck 6 may be lowered to the bottom of the hold 3 to dump the carrier on the spot, or may be moved to a predetermined location to unload the load N.

The dump truck 6 that has finished unloading the load N
Drives the lift winch device 35 to move the lift base member 31
Is raised to the work table 8, passes over the work table 8, and the connecting path plate 17, and moves from the quay 16 to a target place.

When the elevating table member 31 moves down or rises, the elevating guide rod 38 for preventing the swing of the elevating table member 31 moves up and down along the elevating guide hole 37, so that the wind or the wind rises. The shaking accompanying the shaking of the main body 2 can be prevented.

If a predetermined section of the hold 3 is filled by repeating the loading operation as described above,
The drive motor 13 of the moving device 10 is driven to move the worktable 8 in the bow-sail direction A so that the load N can be loaded into the empty part of the hold 3, and the same operation as described above is repeated.

Conversely, when unloading the cargo N in the hold 3 to the outside of the ship, the dump truck 6 emptied of the carrier is moved from the connecting path plate 17 to the work platform 8 and further onto the lift platform member 31. Then, the lifting winch device 35 is driven to lower the lifting platform member 31 into the hold 3, and the load N is loaded on the loading platform of the dump truck 6 by, for example, a cargo-handling vehicle such as a power shovel that has been previously carried into the hold 3. When the load N is fully loaded on the loading platform, the lifting platform member 31 is lifted, and the dump truck 6 crosses over the connecting path plate 17 from the working platform 8 to the quay 16 and goes to the target location.

In addition to the above-described method, it is of course possible to directly load and load the cargo N into the hold 3 from the dump truck 6 loaded on the work table 8. Since the bottom of the ship is liable to be damaged if the load N is loaded and loaded, the load N is unloaded by lowering the dump truck 6 to the hold 3 while the load N is loaded on the dump truck 6 as described above.

As described above, according to the embodiment of the present invention,
A communication board 17 is provided to connect the work table 8 provided on the carrier body 2 to the quay 16, and a loading / unloading vehicle is placed at a corner of the work table 8 to move up and down between the work table 8 and the hold 3. Stand member 31
And a lifting mechanism 32 for raising and lowering the lifting table member 31 is provided, so that a cargo handling vehicle such as a dump truck 6 passes over the connecting path plate 17 and the work table 8 and is carried into the hold 3 to be loaded. Since the loading and unloading of N can be performed, there is no need to provide a large cargo handling device on the quay 16 side, and the loading and unloading of the load N directly to the hold 3 of the transport ship 1 can be performed using a conventional cargo handling vehicle such as a dump truck 6. Therefore, the efficiency of the unloading operation of the load N can be improved.

[0023]

As is apparent from the above description, according to the present invention, a cover body is provided so as to cover a hold provided on a carrier body, and a communication path plate for connecting the land side and the cover body is provided. Since a loading / unloading vehicle such as a dump truck is placed thereon and a lifting / lowering table member for lifting / lowering between the cover body and the hold is provided, and a lifting / lowering mechanism for raising / lowering the lifting / lowering table member is provided, the connecting path plate is rotated. And transfer the cargo handling vehicle from the connecting board to the cover or in the hold, and then directly load and unload the cargo handling vehicle.
