Conventionally, the outreach of land-based shore cranes has been designed based on the width of a single-banamax ship, and even if the width of the container ship is made wider and more containers are loaded, the hatched part as shown in Figure @8 Container 7 cannot be handled due to lack of outreach R of Syrian crane 1.

[Problem that the invention seeks to solve]

For this reason, there are cases in which container ships themselves are equipped with entry cranes, but the disadvantage is that the equipment costs are extremely high.

In other words, if we could create an inexpensive inboard container moving device that compensates for the lack of outreach of shore cranes while using land-based shore cranes with high cargo handling efficiency, it would be possible to carry more containers by leaving a wider container ship.
The operating cost per container can be significantly reduced.

The present invention aims to solve these problems, and provides a container ship equipped with a container moving device, which is equipped with an inexpensive container moving device that compensates for the lack of outreach of simian cranes on wide container ships. The purpose is to provide.

[Means for solving problems]

For this reason, the container ship with a container moving device of the present invention is a wide container ship, and is equipped with a container moving device for stowing containers in a container hold, and the container moving device can move containers that can be moved in the width direction of the ship. A movable cell guide frame structure for stowage, a drive mechanism by which the movable cells can drive the idle frame structure, and a movable cell guide frame structure for supporting the movable cell guide frame structure and guiding its movement in the width direction of the ship. A lower idle rail laid at the bottom of the container hold, and an upper part attached to the inner wall of the container hold to guide the movable cell guide frame structure and prevent it from falling down when the movable cell guide frame structure moves. 〃It is characterized by being configured with an idle rail.

[For production]

In the above-mentioned container ship equipped with a container moving device of the present invention,
The movable cell gamma side frame structure is projected into the outreach of the loading/unloading crane, and after containers are loaded onto the structure, it is guided outside the crane's outreach to the upper idle rail and lower guide rail. Containers are loaded outside the outreach of loading and unloading cranes.

〔Example〕

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.
Figures 1 to 7 show container movement l as an embodiment of the present invention.

and outreach R by the movable cell guide frame structure 3.
An id is formed by continuous cells extending from the inside to the outside of the 7 Utreach R.

The adjacent movable cell γ id 17 and the movable cell guide frame structure 3 are guided at their upper portions by an upper id rail 9 and a V guide roller 10 as shown in FIG.
The adjacent movable cell guide 17 and the movable cell guide frame structure 3 are prevented from falling in the longitudinal direction.

The upper idle rail 9 is laid on the inner wall of the bulkhead 8 as the inner wall of the container hold 20 and extends horizontally in the ship width direction.
0 is restrained and rolled, so that the posture of the movable cell guide 17 adjacent to the movable cell guide frame structure 3 is maintained in a required state.

That is, the movable cell guide frame structure 3 and the adjacent movable cell guide 17 are kept perpendicular to the hull due to the engagement between the upper idle rail 9 and the lower roller 4 and the engagement between the idle roller 10 and the upper idle rail 9. It becomes possible to do V.

Then, as shown in Fig. 2.7, the hydraulic sill 11 as a drive mechanism for the adjacent movable cell guide 17 and the movable cell guide frame structure 3 is connected to the inner wall 6 of the container hold 20 and the movable cell guide frame structure 3. A pair of upper and lower inserts are installed at required locations in the longitudinal direction between the two.

The hydraulic cylinder 11 extends horizontally in the ship width direction, and is adapted to move the movable cell guide frame structure 3 in the ship width direction by expanding and contracting.

This movement of the movable cell guide frame structure 3 is allowed by the link 18 extending or bending, and when the link 18 is fully extended, the movable cell guide frame structure 3 is allowed to move. Link 18. When the adjacent movable cell forms a cell guide extending outside the outreach R of the shore crane 1 by the id 17, and the link 18 is bent, the movable cell guide frame structure 3 extends to the outreach R of the shore crane 1.
Ids are formed when the cells are moved inside.

The hydraulic cylinder 11 is driven by a circuit shown in FIG. 7, and the hydraulic cylinders i2, 13.
