[0002]

2. Description of the Related Art FIG. 7 shows a container ship 2 moored on a quay 1.
FIG. 3 is a schematic view showing a state in which a container 4 is being loaded and unloaded by a container crane 3. In the illustrated container crane 3, a girder 6 projects to the sea side above a leg 5 that can travel along the quay 1. A trolley 7 is provided on the girder 6 so as to be able to traverse, and a spreader 8 is suspended from the trolley 7 via a rope 9 so as to be able to move up and down.

Generally, when a container crane 3 is used to load and unload a container 4 on a container ship 2, the container 4 is gripped by a spreader 8 suspended from a trolley 7, and in this state, the spreader 8 is wound up and the trolley 7 is moved to the container. Ship 2
A series of operations of moving the container 4 to the upper target position, lowering the spreader 8 and loading the container 4 on the container ship 2 is performed.

At this time, as shown in FIG. 8, the container 4 is first loaded into a container hold 10 inside the container ship 2, and after the container hold 10 is filled with the container 4, the container 4 is placed on the quay 1 or the like. The retracted hatch cover 11 is installed on the upper side of the container hold 10 so that the containers 4 are stacked on the hatch cover 11.

[0005]

However, when loading the container 4 into the container hold 10, the container hold 10 is moved from the trolley 7 of the container crane 3 to the container hold 10.
Since the distance to the container 4 becomes long, the container 4 gripped and suspended by the spreader 8 tends to swing due to the influence of wind and inertia, and there is a problem that it takes time to insert the container 4 into the container guide 12.

A container guide 12 for guiding the container 4 up and down is provided in the container hold 10, while the container 4 is provided on the hatch cover 11.
Since there is no guide means for guiding the ascending and descending of the containers 4, there is a problem that when the containers 4 are stacked on the hatch cover 11, it is difficult to align the containers 4 in each stage.

The present invention has been made in view of the above-mentioned circumstances, and when loading a container into a container hold, the container can be easily inserted into a container guide, and the container is stacked on a hatch cover. Also in this case, it is an object to improve the cargo handling efficiency of the container with respect to the container ship by making it possible to easily align the containers at each stage.

[0008]

SUMMARY OF THE INVENTION The present invention provides a pair of traveling girder supported by a traveling device so as to be able to travel in the longitudinal direction of a hull while straddling a hatch cover of a container ship in the width direction of the hull.
Slightly larger than the longitudinal dimension of the container, they are separated in the longitudinal direction of the hull and connected outside the hatch cover, and a traversing device is installed on each traveling girder so as to be able to traverse in the hull width direction. On the other hand, a pair of guide columns extending to a position higher than a predetermined number of stages of containers stacked on the hatch cover are separated from each other in the hull width direction to be erected, and a rectangular shape capable of vertically passing containers to be unloaded by a container crane.

And positioning the entry guide frame at a predetermined container stacking position, and suspending the container to be unloaded by the container crane while guiding the ridge formed by the two sides of the container vertically through the guide member of each guide column through the entry guide frame. take down.

After the first-stage containers are landed on the hatch cover, the second and subsequent containers may be sequentially stacked on the first-stage containers in the same manner. The alignment of the containers in each stage is naturally performed, and the containers in each stage are stacked in a state of being accurately overlapped.

Next, when the stacking operation at the predetermined container stacking place is completed, the guide members of each guide column are retracted in the longitudinal direction of the hull so that the guide members and the containers do not interfere with each other in the hull width direction, and the stacking is completed. The traversing device is traversed on the traveling girder in such a manner that a predetermined number of containers are passed under the entry guide frame supported in a gate shape by the respective guide columns, and the containers are moved in the same manner as described above at the new container stacking place. Stacking is performed while guiding vertically.

When the container stacking operation is repeated and the containers stacked in a predetermined number of rows are arranged in a line in the hull width direction, the traversing device and the traveling girder are integrally connected, and the entire device is lifted. Move to a place where container stacking is not performed, and perform container stacking work in the same procedure.

At this time, if lifting metal fittings for enabling the container crane to be gripped by the spreader are provided at the four corners of the entry guide frame so as to be able to be retracted from the frame, the lifting metal fittings can be placed inside the frame during operation. , And the lifting hardware can be arranged in the frame and held by the spreader of the container crane only when moving, so that the entire apparatus can be lifted and moved using the container crane.

Further, a rectangular entry guide frame 19 through which the container 4 to be unloaded by the container crane 3 (see FIG. 7) can pass vertically is provided on each of the traversing devices 17 by a pair of guide columns 18 standing upright. An entry guide portion 20 is supported by the upper end in a gate shape, and is formed inside the entry guide frame 19 so as to gradually project upward and out of the frame so that the container 4 can be guided well into the frame.

Each of the guide columns 18 has two types of guide members 21 and 22 for vertically guiding a ridge formed by two sides of the container 4 through the entry guide frame 19.
3 is disposed so as to be able to retreat in the longitudinal direction of the hull.
As shown in detail in FIG. 4 and one of the guide members 21,
It extends in the vertical direction over substantially the entire length of the guide column 18, and guides the side surfaces at both ends in the longitudinal direction of the container 4,
Rod members 23 protruding from a plurality of appropriate locations in the vertical direction.
Are slidably inserted into bearings 24 provided on the guide column 18 side, and can be advanced and retracted in the longitudinal direction of the hull by actuators 25 mounted at a plurality of vertical positions of the guide column 18. The guide member 22 is divided and arranged at a plurality of positions in the vertical direction of the guide column 18 so as to guide the side surfaces at both ends in the width direction of the container 4. The actuator 26 mounted on the side can move forward and backward in the longitudinal direction of the hull via a link mechanism 27.

On the outside of each of the guide members 22, a steady rest 28 for restraining the displacement of each of the guide members 22 in the hull width direction extends vertically over substantially the entire length of the guide column 18. I have.

Further, as shown in FIGS. 3 and 5, at the four corners of the entry guide frame 19, a lifting metal fitting 29 for enabling the container crane 3 to be gripped by the spreader 8 is provided with an actuator around a rotating shaft 30. It is provided so that it can be rotated from the inside of the frame by being rotated by 31.

That is, the spreader 8 of the container crane 3
Is a gripping method for gripping the four corners on the upper surface of the container 4. If the lifting brackets 29 are fixed and arranged, the lifting brackets 29 project into the entry guide frame 19 and the container 4 cannot be passed in the vertical direction, so that each lifting metal 29 is retracted from the frame at the time of work, and only when necessary, each lifting metal 29 is placed in the frame and held by the spreader 8 of the container crane 3. I have to get it.

According to such a lifting device for container handling, when the hatch cover 11 is removed and the container 4 is loaded into the container hold 10, the traveling girder 15 is moved forward and backward by the traveling device 14. After traveling to the appropriate position in the direction, the traversing device 17 on each traveling girder 15
Is traversed in the width direction of the hull, and the guide column 18 and the entry guide frame 19 are positioned immediately above the predetermined container guide 12.
The ridge formed by the two side surfaces of the container 4 through the entry guide frame 19 is formed by the guide members 21 and 22 of the respective guide columns 18.
The container 4 is hung down while being guided vertically, and the container 4 is inserted into and accommodated in the container guide 12 immediately below.

When the container 4 is completely accommodated in the predetermined container guide 12, the traversing device 17 on each traveling girder 15 is traversed in the width direction of the hull and a new container guide 1 is moved.
2 and the container 4 is inserted into and accommodated in the container guide 12 while guiding the container 4 in the vertical direction in the same manner as described above. After the container 4 is loaded, each traveling girder 15
To move up and down a new row by moving the ship forward and backward, and carry out container loading work in the same procedure.

After that, after the container hold 10 is filled with the container 4, the hatch cover 11, which has been evacuated to the quay or the like, is installed above the container hold 10 and the container 4 is stacked on the hatch cover 11. .

That is, after the traveling girder 15 is moved to an appropriate position in the longitudinal direction of the hull by the traveling device 14, the traversing device 17 on each traveling girder 15 is traversed in the hull width direction to guide the guide post 18 and the entry guide frame. The container 4 to be unloaded by the container crane 3 is positioned at a predetermined container stacking position, and the ridge formed by the two sides of the container 4 through the entry guide frame 19 is positioned at each guide column 18.
While being guided vertically by the guide members 21 and 22.

When stacking the containers 4 on the hatch cover 11, the traveling girder 15 is moved to an appropriate position in the longitudinal direction of the hull by the traveling device 14, and then the traversing device 17 on each traveling girder 15 is moved in the hull width direction. , The guide post 18 and the entry guide frame 19 are positioned at a predetermined container stacking position, and the container 4 to be unloaded by the container crane 3 is moved through the entry guide frame 19 by the guide members 21 and 22 of the respective guide posts 18. The ridge formed by the two side surfaces of No. 4 is suspended while being guided vertically.

After the first-stage containers 4 are placed on the hatch cover 11, the second-stage and subsequent containers 4 may be sequentially stacked on the first-stage containers 4 in the same manner. In this case, the alignment of the containers 4 in each stage is automatically performed, and the containers 4 in each stage
Pile up in a state of being accurately superimposed.

Next, when the stacking operation at the predetermined container stacking place is completed, the guide members 21 and 22 of each guide post 18 are retracted in the longitudinal direction of the hull, and the guide members 21 and 22 and the container 4 are moved in the width direction of the hull. The container 4 of a predetermined number of stacked levels is set in a state where there is no interference,
The traversing device 17 is traversed on the traveling girder 15 so as to pass under the entry guide frame 19 supported by each guide column 18 in a gate shape, and the container 4 is moved up and down at a new container stacking place in the same manner as described above. Stacking while guiding in the direction.

When the containers 4 stacked in a predetermined number of stages are arranged in a line in the hull width direction by repeating the stacking operation of the containers 4 in this manner, the traversing device 17 and the traveling girder 15
Then, the entire apparatus is lifted and moved to a place where the containers 4 have not yet been stacked, and the container stacking operation is performed in the same procedure.

At this time, each lifting bracket 29 retracted from the frame of the entry guide frame 19 is rotated around an axis of rotation 30 by an actuator 31 so as to protrude into the frame. Can be held by the spreader 8, and the entire apparatus can be lifted and moved using the container crane 3.

When the container 4 is to be discharged from the container ship 2, it is needless to say that the above procedure may be reversed.

When the traversing device 17 and the traveling girder 15 are integrally connected and the whole device is lifted, for example, as shown in FIG. The sheaves 33, 34 are provided at the tip of each of the side portions 15a, 15a, and the sheaves 35, 36, 37, 38 are provided near the upper end of each guide column 18, respectively. The weight 41 with the upper and lower parts 39 and 40 mounted thereon is moved to
The elevating rope 42 is sequentially wound around sheaves 33, 35, 36, 39, 37, 38, and 34, then inverted, wound in the reverse order, and stretched endlessly. Further, a connecting rope 4 is provided between the winding device 43 provided on each traversing device 17 and the sheave 40 below the weight 41.
4 and the take-up device 43 takes up the connecting rope 44 so that the weight 41 is pulled down so that both side portions 15a and 15a of the traveling girder 15 can be erected via the elevating rope 42. Each traversing device 17 has
A rail clamp 45 is provided so as to be integrally connected to a central portion in the longitudinal direction of each traveling girder 15, and a plurality of jack-up devices 46 are arranged on the lower surface of the central portion 15b of each traveling girder 15 in a well-balanced manner. What should I do?

In this way, when the entire apparatus is lifted and moved using the container crane 3, each traversing device 17 is integrally connected to the longitudinal center portion of each traveling girder 15 by the rail clamp 45. Above, the traveling device 14 of each traveling girder 15 is floated from the upper deck passage 13 by the jack-up device 46, and then the winding device 4
By winding up the connecting rope 44 in step 3, the weight 41 is pulled down, and both side portions 15a, 15a of the traveling girder 15 are raised upward via the elevating rope 42, so that the entire apparatus can be made compact and can be lifted. .

According to the mechanism using the weight 41 as shown in the figure, the lifting rope 42 can be prevented from being loosened by the weight 41 and the power required for the winding device 43 can be greatly reduced. There are advantages.

Therefore, according to the container loading / unwinding guide apparatus as described above, the container 4 to be unloaded by the container crane 3 is moved vertically in a position above the hatch cover 11 where no guiding means is conventionally provided. Can be suspended while being guided from the trolley 7 of the container crane 3 without any guide means. At such a short suspension distance, the trolley 7 is gripped by the spreader 8. Since the container 4 to be hung down is significantly suppressed from swaying due to the influence of wind or inertia, handling of the container 4 at the time of cargo handling is facilitated, and the cargo handling efficiency can be greatly improved.

In particular, when loading the container 4 in the container hold 10, the container 4 to be unloaded by the container crane 3 is guided vertically from a relatively short hanging distance in which the occurrence of shaking is suppressed. Since the container 4 can be inserted into the container guide 12 in the hold 10, the container 4 can be easily inserted into the container guide 12.

Also, when the containers 4 are stacked on the hatch cover 11, the containers 4 of a predetermined number of stages to be stacked on the hatch cover 11 can be stacked while being guided in the vertical direction. Can be easily adjusted.

Incidentally, the lifting and lowering guide device for container handling according to the present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention.

[0046]

According to the above-described lifting and lowering guide device for container handling according to the present invention, a container to be unloaded by a container crane is guided in a vertical direction at a position above a hatch cover which has not provided any guide means in the past. Since it is possible to suspend the container from the trolley of the container crane without guide means, the container suspended and spread by the spreader at such a short suspending distance can reduce the wind. And swaying due to the influence of inertia is significantly suppressed, which makes it easy to handle containers during cargo handling work and greatly improves cargo handling efficiency.Especially, when loading containers in container holds, Relatively short containers that are controlled by container cranes Since the container can be guided in the vertical direction from the hanging distance and inserted into the container guide in the container hold, the container can be easily inserted into the container guide, and when the containers are stacked on the hatch cover, In addition, since a predetermined number of containers to be stacked on the hatch cover can be stacked while being guided in the vertical direction, various excellent effects such as easy alignment of the containers in each stage can be achieved. obtain.
