Description

DETAILED DESCRIPTION OF THE INVENTION “Industrial Application Field” The present invention has been newly developed to improve the work efficiency of unloading a docked container ship to a quay or loading a berth to a container ship. It is about the container guide.

“Conventional technology” Conventionally, container cranes have been used for unloading and loading containers on the quay and between the docked container ships.

FIG. 7 shows a conventional example thereof, in which reference numeral 1 is a container crane, 2 is a container ship, and 3 is a container loaded on the container ship 2.

The container crane 1 is permanently installed on the quay 4, and the girder 6 is horizontally supported by the frame body 5 toward the sea side, and the length thereof can be extended to the tip of the girder 6. The booms 7 are vertically linked so that
A trolley 8 moving along the girder 6 and the boom 7 is provided with a spreader 9 which is a container suspending device so as to be vertically movable by a hoisting device 10. Further, in the frame main body 5, the tips of the legs 11 spaced apart from each other by
It is mounted on a guide rail 12 laid along the guide rail 12, and is movable by the guide rail 12 in the longitudinal direction of the hull of the container ship 2. Further, the frame body 5 is provided with a relay stand 14 on which the container 3 is temporarily placed, and an auxiliary girder 15 which is horizontally arranged above the relay stand 14. Is an auxiliary trolley 17 that is equipped with a container hanger 16 and can run along the auxiliary girder 15.
Is provided.

The cargo handling work using the container crane 1 as described above will be described below by taking the case of unloading as an example.

First, as shown in Fig. 7, the container ship 2 docked
With the boom 7 projecting upward, the trolley 8 is reciprocated along the girder 6 and the boom 7,
The containers 3 loaded on the container ship 2 are sequentially transferred to the relay stand 14 one by one. Then, the container 3 carried on the relay stand 14 is a chassis (carriage) 18 which sequentially runs on the quay 4 by the container suspension 16 of the auxiliary trolley 17 until the trolley 8 carries the next container 3. And is transported by the chassis 18 to the desired location.

"Problems to be Solved by the Invention" In the container crane 1 as described above, the transport distance of the container 3 by the auxiliary trolley 17 is far longer than that of the trolley 8 as can be seen from FIG. It is small and therefore the time required to unload one container 3 is limited by the trolley 8
It is the time from when the container 3 is located above the container 3 to the transfer stand 14 and when it is returned to the next container 3 to be unloaded again (hereinafter referred to as cycle time). In order to improve work efficiency by shortening the cycle time of the trolley 8.

One of the ways to reduce this cycle time is:
Although it is possible to increase the traveling speed of the trolley 8 and the ascending / descending speed of the spreader 9 in the container crane 1, it is difficult to greatly shorten the design due to such a method, and when the container crane 1 is newly installed. It is still good, but when using the existing container crane 1, it requires substantial remodeling and is virtually impossible.

Further, in general, this type of container crane 1 is designed such that the length of the boom 7 is the maximum width of a so-called Panamax type ship, and the boom 7 of the ship is larger than the width of the ship. Since the tip end does not reach the side edge of the hull, the work efficiency is extremely poor. In such a case, the traveling speed of the trolley 8 and the spreader 9 described above are used.
The effect cannot be improved by increasing the running speed of.

The present invention has been made in view of the above circumstances, and effectively utilizes the cycle time of the trolley in the container crane even when using an existing container crane or in the case of a ship having a very large hull width. It is an object of the present invention to provide a container guide which can be significantly shortened and therefore can significantly reduce the working time and efficiency of container handling.

[Means for Solving Problems] A container guide according to the present invention is a container which is erected on a deck of a container ship and forms a framework for preventing a container loaded on the deck from collapsing. It is provided with a pillar that is erected higher than the container loading range and a beam that is horizontally supported by the pillar along the width direction of the hull. A rail portion that is provided in a plurality of stages in the height direction with the uppermost one of the columns being the uppermost position, and that allows the container transfer device that grips and transports the container to the beam to travel in the width direction of the hull. And a rail portion that allows the relay container cradle on which the container is placed to travel in the width direction of the hull inside the container transfer device.

"Operation" A container ship equipped with the container guide according to the present invention uses the container guide to prevent the container loaded on the deck from collapsing during navigation. When unloading or loading, install an onboard container transfer device and a relay container cradle on the beam of the container guide, and use the container guide as a travel guide to transfer these containers. A series of container loading and unloading can be performed by cooperation among the loading device, the relay container cradle, and the container crane.

Therefore, when carrying a container between the container ship and the quay, the container is moved by the container crane installed on the quay side. And it can be done only between the container cradle for relay,
The distance traveled by the container crane is shortened by the amount transported by the container transfer device on the container ship and the container cradle for relay. In this case, the mileage of the trolley on the container crane is reduced much more than the conventional case where the auxiliary trolley is arranged on the container crane. The time is significantly shortened, and the working time and efficiency of container handling can be significantly shortened.

In addition, the onboard container transfer device and the relay container cradle are usually stored on the quay side, and when the container ship berths on the quay side, it should be installed on the container guide on the container ship by a container crane. If so, the equipment of the container ship can be only a container guide as a simple structure, and the cost required for the onboard equipment can be reduced.

In addition, as described above, a shipboard container transfer device and a relay container cradle are installed on the container guide, and a series of cargo handling operations are carried out by cooperation between these container transfer devices, relay container cradle, and container crane. If the work is to be carried out, even in the case of a ship whose hull width exceeds the maximum value of the Panamax type, it is sufficient to run the onboard container transfer device within the range where the container crane cannot reach, and the hull width is Even in the case of a very large ship, the work and efficiency of container handling can be greatly reduced.

The container guide 19 is a frame body that is erected on the deck 2a of the container ship 2 in order to save manpower required for lashing, and is arranged on the deck 2a of the container ship 2 in an upright state in two rows along the width direction of the ship. The stanchions 21 are provided upright, and the beams 23 and 24 are supported by the stanchions 21 so as to extend vertically in two stages and extend horizontally along the width direction of the hull.

The aforementioned two columns of columns 21 are each composed of four columns 21 arranged along the width direction of the hull. Also,
The distance between each row is set to be larger than the size of the container 3 loaded on the deck 2a, and each row is exactly in the gap C (see FIG. 3) between the containers loaded in multiple stages. Considered to be located. Further, the height dimension of each of the columns 21 is selected so that the upper end position thereof projects above the uppermost one of the containers 3 stacked on the deck 2a.

The beam 23 is attached to the upper ends of the columns 21 of each row, while the beam 24 is attached to the position lower than the height dimension of the container 3 from the beam 23 or more. Although the number of beams is two in the upper and lower stages in this embodiment, it goes without saying that the number of beams may be increased.

The above-mentioned beams 23 and 24 are the above-mentioned shipboard container transfer device.
The rails 23a and 24a are respectively provided on the upper portions of the guides so that the rails 23a and 24a can be used as guides for the 20 (see FIG. 3). Each of the rail portions 23a and 24a described above serves as a traveling path for a main body frame and a relay container pedestal, which will be described later, and is provided over the entire width of the hull.

This container transfer device 20 is for gripping and carrying the container 3, is installed on the beam 23 of the container guide 19 which is erected on the deck 2a of the container ship 2, and can travel in the width direction of the ship. The main body frame 26, the hoisting device 27 attached to the upper frame of the main body frame 26, and the hoisting device
A spreader 28 that holds the container 3 so that it can be lifted up and down by a 27, and a relay that can run in the width direction of the hull separately from the body frame 26 on the beam 24 of the container guide 19 that passes under the body frame 26. It is configured to include a container receiving stand 29.

The main body frame 26 is provided with traveling wheels 26a at the lower ends of legs located at both ends of the upper frame, and the traveling wheels 26a are set on the above-mentioned rail portion 23a, and drive (not shown) is performed. When the traveling wheels 26a are driven by the device,
It is possible to travel from end to end of the hull along the rail portion 23a, and as a result, it is possible to run in the same direction as the trolley 8 directly below the trolley 8 of the container crane 1 installed on the quay 4 side. Has become. The bottom of the body frame 26 is open so that the spreader 28 can be freely moved up and down.

The rail portion 24a described above is provided on the beam 24,
They are laid in parallel inside the rail portion 23a. On the other hand, the relay container pedestal 29 has a plate shape on which the container 3 can be placed, and traveling wheels 29a for riding on the rail portions 24a are provided on both sides of the cradle 29. The cradle 29 can be advanced and retracted in the width direction of the hull by passing under the body frame 26.

The height of the main body frame 26 is set so that a space for accommodating the container 3 remains above the relay container cradle 29 even when the relay container cradle 29 enters below.

The setting of the main body frame 26 and the relay container cradle 29 on the container guide 19 is performed by the container crane 1 on the quay side.

The traveling of the main body frame 26 and the relay container cradle 29 described above is controlled by a controller (not shown).

This control device is a position detecting device for detecting the position of the chassis 18 on land, the position of the container 3 that is subsequently handled by the main body frame 26, and the current positions of the trolley 8, the main body frame 26 and the relay container cradle 29. And a calculation device that receives signals from these position detection devices and calculates the movement distance of the main body frame 26 and the relay container cradle 29 so that the cycle time of the trolley 8 becomes the shortest. The control device controls the relay container cradle 29 and the trolley 8.
The position where you meet is automatically adjusted to the optimum position.

As described above, the container ship equipped with the container guide 19
The container guide 19 is used to prevent the container 3 loaded on the deck 2a from falling during navigation, but when unloading or loading the container 3 by berthing on the quay 4 serving as a container terminal. , The beam 23 of the container guide 19
・ The shipboard container transfer device 20 is installed on 24, and the container guide 19 is used as a travel guide for the shipboard container transfer device 20, and installed on the shipboard container transfer device 20 and the quay side. A series of container handling operations can be performed in cooperation with the existing container crane 1.

Container handling using the container transfer device 20,
An example of unloading the container ship 2 to the chassis 18 on the quay 4 will be described below.

First, as shown in FIG. 1, the main body frame 26 is moved above the container 3 to be unloaded first, and the spreader 28 is positioned right above the container 3 to be unloaded.

At this time, the relay container pedestal 29 is retracted to a position away from the main body frame 26 so as not to interfere with the lifting and lowering of the spreader 28.

Then, next, the spreader 28 is lowered to grip the containers 3 loaded on the container ship 2. Then, as shown in FIG. 2, the spreader 28 is raised to pull up the container 3, and when the lower end position of the container 3 reaches a position slightly above the relay container cradle 29, the spreader 28 is stopped from rising. .

Then, one or both of the relay container pedestal 29 and the main body frame 26 are made to travel so that the relay container pedestal 29 is put under the container 3 suspended in the main body frame 26.

Then, next, the spreader 28 is lowered and the suspended container 3 is placed on the relay container pedestal 29, and then the grip by the spreader 28 is released, and the relay container pedestal 29 is placed outside the main body frame 26. To leave.

Then, next, the spreader 9 suspended on the trolley 8 of the container crane 1 is lowered, and the container 3 placed on the relay container cradle 29 is pulled up. 1 Trolley 8 is run and container 3 is attached to chassis 18 on the quay.
However, the main body frame 26 and the relay container cradle 29 move to the next cargo handling operation during that time. That is, the main body frame 26 takes out the second container 3 from the inside of the ship by the same operation as described above, while the relay container cradle 29 receives the second container 3 and then the first container 3
So that you can meet the trolley 8 of the container crane 1 that comes back after you unload it on the chassis 18 earlier,
Drive toward the quay 4 side.

In this case, the position where the trolley 8 of the container crane 1 and the relay container cradle 29 meet is the position of the chassis 18 on land, and then the position of the container 3 loaded by the main body frame 26, the trolley at the present time. 8 and the position of the relay container cradle 29, etc., the optimum position for eliminating unnecessary waiting time is calculated.

Then, at the meeting point, stop the traveling of the trolley 8 of the container crane 1 and the relay container cradle 29,
The container 3 is transferred between the two, and then the relay container cradle 29 receives the third container 3 to receive the main frame 26.
Driven towards, the container crane 1 goes to unload the second container 3 onto the chassis 18. The same operation is repeated thereafter.

When the container 3 is loaded onto the container ship 2 from the quay, the trolley 8 of the container crane 1, the relay container cradle 29, and the like may be operated in the reverse manner.

When the cargo handling is performed as described above, for the second and subsequent containers 3, the relay container cradle 29 and the main body frame 26 travel on the hull, and the container crane 1
The traveling distance of the trolley 8 on the container crane 1 is reduced because the position where the container 3 is transferred to the trolley 8 is closer to the quay. In this case, the rate at which the traveling distance of the trolley 8 is reduced is much larger than the case where the auxiliary trolley is provided on the container crane as in the conventional case.
As a result, the cycle time of the trolley 8 on the container crane 1 is significantly reduced,
It is possible to significantly reduce the efficiency.

Further, if the container guide 19 is erected on the deck 2a of the container ship and the container transfer device 20 is set on the container guide 19 in this way, the hull width of the ship exceeds the maximum value of the Panamax type. In this case, if the container crane 1 does not reach, the main body frame 26 and the relay container pedestal 29 may be moved, and the container transfer device 20 is effective even in the case of a very wide ship. It is possible to significantly reduce the work efficiency of container handling.

Further, in the container transfer device 20 described above, both the main body frame 26 and the relay container pedestal 29 are installed on the container guide 19, but in that case, the relay container pedestal 29 is installed from the main body frame 26. Is also attached to the lower beam 24, so the container 3 by the spreader 28 of the main frame 26
You can keep the vertical distance of the
It is possible to shorten the cargo handling time between the main body frame 26 and the relay container cradle 29, and it is also possible to reduce the size of the main body frame 26 to promote compactness of the device. Even if the gap in the height direction between the cantilever of the container crane and the cell guide on the container ship is small, the work can be efficiently proceeded without any trouble.

In the above-mentioned embodiment, each of the main body frame 26 and the relay container pedestal 29 was designed to run on rails, but a trackless type without rails or a combination of rack and pinion, etc. Can also be

Further, in the above-described embodiment, the main body frame 26 of the container transfer device 20 and the relay container pedestal 29 are made to travel on the beams 23 and 24 having different height positions, respectively. As shown in FIG. 6, both of them may be caused to travel on the uppermost beam 23.

"Effect of the invention" As is clear from the above description, the container ship equipped with the container guide according to the present invention uses the container guide to prevent the container loaded on the deck from collapsing during navigation. When unloading or loading containers at the quay which will be the container terminal, install the container transfer device and the relay container cradle on the beam of the container guide, It is possible to move along the width direction, and a series of container loading and unloading can be performed by mutual cooperation between the container transfer device and the relay container cradle and the container crane on the quay.

In this case, the shipboard container transfer device is, for example, a main body capable of traveling in the width direction of the hull between a pair of beams installed in parallel at the same height position as a traveling guide. A container is constructed by having a frame and a spreader or the like that can be lifted up and down on the main body frame to hang the container, and the relay container cradle can pass through the inside of the main body frame, The container loading and unloading can be performed by the container transfer device and the relay container cradle.

Therefore, when carrying a container between the container ship and the quay, the container is moved by the container crane installed on the quay side. And it can be done only between the container cradle for relay,
The distance traveled by the container crane is reduced by the amount transported on the container ship. In this case, if the mileage of the trolley on the container crane is reduced, it is much larger than the case of deploying an auxiliary trolley on the container crane as in the past, and therefore the cycle of the trolley on the container crane is reduced. Time has been significantly reduced,
It is possible to significantly reduce the working time and efficiency of container handling.

Further, the onboard container transfer device and the relay container cradle are usually stored on the quay side, and when the container ship berths on the quay side, it should be installed on the container guide on the container ship by a container crane. For example, the equipment of the container ship may be only the container guide as a simple structure, and the cost required for the onboard equipment can be reduced.

In addition, as described above, if the onboard container transfer device and the relay container cradle are installed on the container guide to perform a series of cargo handling work by mutual cooperation with the container crane, Even if the vessel exceeds the maximum value of the Panamax type, it is sufficient to run the onboard container transfer device and the relay container cradle within the range that the container crane cannot reach, and the vessel width is very large. Even in the case of, it is possible to significantly reduce the work efficiency of container handling.
