Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to unloading from a docked container ship to a quay,
It also relates to a newly developed container guide to improve the efficiency of loading cargo from a quay to a container ship.

"Prior Art" Conventionally, container cranes have been used to unload and load containers between a quay and a container ship that has docked.

FIG. 7 shows a conventional example, 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 a girder 6 is horizontally supported by the frame body 5 toward the sea side, and its length can be extended at the tip of the girder 6. A boom 7 is connected so as to be movable up and down, and a spreader 9, which is a container hoist, is provided on a trolley 8 that moves along the girder 6 and the boom 7 so as to be movable up and down by a hoisting device 10. . In the frame body 5, the tips of the legs 11 spaced apart from each other at a predetermined interval rest on guide rails 12 laid along the quay 4, and the guide rails 12 support the container ship 2 in the longitudinal direction of the hull of the container ship 2. It is possible to move to. The frame body 5 also includes a relay stand 14 on which the container 3 is temporarily placed, and an auxiliary girder 15 horizontally arranged above the relay stand 14.
The auxiliary girder 15 is provided with an auxiliary trolley 17 that is equipped with a container hanger 16 and can run along the auxiliary girder 15.

The cargo handling work using the container crane I as described above will be explained as follows, taking the case of unloading as an example.

First, as shown in FIG.
is reciprocated along the girder 6 and boom 7, and the containers 3 loaded on the container ship 2 are transferred one by one to the transfer stand 14.

Then, the container 3 carried onto the transfer stand 14 is moved to a chassis (truck) 18 that is sequentially moved on the quay 4 by the container hoist 16 of the auxiliary trolley 17 until the trolley 8 brings the next container 3. and is transported to a desired location by this chassis 18.

[Problems to be solved by the invention] By the way, in the above-mentioned container crane,
The transport distance of the container 3 by the auxiliary trolley 17 is the fourth
As can be seen from the figure, the transport distance of the trolley 8 is much smaller, and therefore the time required to unload one container 3 is much smaller than the transport distance of the trolley 8 after the trolley 8 is located on either side of a given container 3. This is the time it takes to move the container 3 to the transfer stand 14 and return it to the next container 3 to be unloaded (hereinafter referred to as cycle time).In order to shorten the container handling time and increase work efficiency, It becomes necessary to shorten the cycle time of said trolley 8.

One possible way to shorten this cycle time is to increase the running speed of the trolley 8 and the lifting speed of the spreader 9 in the container crane 1.
With such a method, it is difficult to significantly shorten the time due to design reasons, and although it is still possible to install a new container crane I, when using an existing container crane I,
This would require extensive modification and is virtually impossible.

In addition, this type of container crane 1 is generally designed so that the length of its boom 7 is the maximum width of a so-called Panamax type ship. Since the tip cannot reach the side edge of the hull, the work efficiency is extremely poor, and in such a case, the above-mentioned method of increasing the traveling speed of the trolley 8 or the traveling speed of the spreader 9 cannot be effective. .

This invention was made in view of the above-mentioned circumstances, and even when using an existing container crane or in the case of a ship with a very wide hull, it is possible to effectively utilize the trolley cycle time of the container crane. It is an object of the present invention to provide a container guide which can significantly reduce the time and therefore the working time and efficiency of container cargo handling.

"Means for Solving the Problems" The container guide according to the present invention is installed on the deck of a container ship to form a framework for preventing containers loaded on the deck from collapsing. The structure includes a column that stands upright on top of the ship, and a beam that is supported by the column so as to extend horizontally along the width direction of the ship, and the column has an upper end position that is The height dimension of the beam is selected so that it protrudes above the topmost container loaded on the deck, and the beam has a height that extends above the upper end of the support column in front of and behind the containers loaded on the deck. They are arranged in multiple stages in the height direction, with the topmost stage being the highest, and are configured to be used as travel guides for a shipboard container transfer device that grasps and transports containers.

"Function" A container ship equipped with a container guide according to the present invention uses the container guide to prevent containers loaded on the deck from collapsing during navigation, but when the container ship berths at a quay serving as a container terminal, containers are When unloading or loading, the shipboard container transfer device is installed on the beam of the container guide, and the container guide is used as a traveling guide for the shipboard container transfer device. A series of container loading and unloading operations can be carried out through cooperation between the container transfer equipment and the container crane installed on the quay side.

In this case, the shipboard container transfer device may include, for example,
A main body frame that can run in the width direction of the hull between the pair of beams using a pair of beams installed in parallel at the same height position as a travel guide, and a container that is suspended from the main body frame so that it can be raised and lowered. If the container is configured to include a spreader or the like capable of suspending containers, container cargo handling on a container ship can be carried out entirely by the above-mentioned shipboard container transfer device.

Therefore, when handling containers between a container ship and a quay, the movement of containers by a container crane installed on the quay side is carried out between a container transport chassis waiting on the quay and the container transporter on the ship. The distance traveled by the container crane can be reduced by the distance traveled by the onboard container transfer device on the container ship. In this case, the reduction in travel distance of the trolley on the container crane is much greater than in the conventional case where an auxiliary trolley is provided on the container crane. The cycle time will be significantly shortened, making it possible to significantly reduce container handling time and efficiency.

In addition, if the above-mentioned shipboard container transfer device is normally stored on the quay side and installed on the container guide on the container ship by a container crane when the container ship docks at the quay, it is possible to install the container ship's equipment on the container guide. Therefore, it is possible to suffice with a container guide as a simple structure, and it is also possible to reduce the cost required for onboard equipment.

In addition, if a shipboard container transfer device is installed on the container guide as described above, and a series of cargo handling operations are performed by cooperation between the container crane and the shipboard container transfer device, the hull width can be reduced to Panamax. Even in the case of a ship exceeding the maximum value for its type, the above-mentioned shipboard container transfer equipment can be used to cover areas that the container crane cannot reach, and even in the case of a ship with a very large hull width, container handling operations and Efficiency can be significantly reduced.

Embodiment FIGS. 1 to 3 show an embodiment of a container ship equipped with a container guide according to the present invention.

The two rows of struts 21 described above each include four struts 21 arranged along the width direction of the hull. In addition, the distance between each row is set to be larger than the dimensions of the containers 3 loaded on the deck 2a, and each row is exactly spaced in the gap C between the containers stacked in multiple stages (see Figure 3). Care has been taken to position the columns. Also,
The height dimension of each support column 21 is selected so that the upper end thereof protrudes above the topmost container 3 loaded on the deck 2a.

The beams 23 are attached to the upper ends of the columns 21 in each row, while the beams 24 are attached at positions lower than the beams 23 by more than the height of the container 3. In addition,
In this embodiment, the number of beams is set to two levels, upper and lower, but it goes without saying that the number of beams may be increased to more than that.

The six beams 23 and 24 described above are configured such that rail portions 23a and 24a are provided at their upper portions, respectively, so that they can be utilized as traveling guides for the aforementioned shipboard container transfer device 20 (see Fig. 3). ). Then, each of the above-mentioned rail portions 23
A.24a serves as a running path for the main body frame and relay container receiver, which will be described later, and is provided over the entire width of the hull.

This container transfer device 20 is for gripping and transporting the container 3, and is installed on the beam 23 of the container guide 19 erected on the deck 2a of the container ship 2, and is movable in the width direction of the ship. a main body frame 26, a hoisting device 27 attached to the upper frame of this main body frame 26, a spreader 28 that is held movably up and down by this hoisting device 27 and hangs the container 3, and the main body frame 26.
The relay container receiver is configured to include a stand 29 that can run under the beam 24 of the container guide 19 in the width direction of the hull separately from the main body frame 26.

The main body frame 26 is provided with running wheels 26a at the lower ends of the legs located at both ends of the upper frame, and the running wheels 26a are set on the above-mentioned rail portion 23a and driven by a drive (not shown). When the traveling wheels 26a are driven by the device, they can travel along the rail portions 23a from one end of the hull to the other, and as a result, the trolley 8 of the container crane 1 installed on the quay 4 side It is possible to run directly under the trolley in the same direction as the trolley 8. Further, the bottom of this body frame 26 is open, and the spreader 28
can be raised and lowered freely.

The above-mentioned rail portion 24a is provided on the beam 24, and is laid parallel to the inside of the rail portion 23a. On the other hand, the stand 29 of the relay container holder has a plate shape on which the container 3 can be placed, and the rail portions 29 are placed on both sides of the stand 29.
Running wheels 29a are provided to ride on the main body frame 26, and the relay container receiver is moved by the drive device 30 to the main frame 26.
It is possible to move forward and backward in the width direction of the ship by passing under it.

The height of the main body frame 26 is such that even when the relay container holder 29 enters under it, the relay container holder does not reach the pedestal 29.
The space is set so that a space capable of accommodating the container 3 remains above the container.

The main body frame 26 and the relay container receiver are set on the container guide 19 by the container crane 1 on the quay side.

The movement of the main body frame 26 and the relay container holder 29 described above is controlled by a control device (not shown).

This control device determines the position of the chassis 18 on land, the position of the container 3 handled by the main body frame 26, and the current position of the trolley 8, main body frame 26, and relay container receiver on the stand 2.
In response to the signals from these position detecting devices, the main body frame 26 and the relay container receiver adjust the moving distance of the stand 29 so that the cycle time of the trolley 8 is minimized. The controller is equipped with a calculation device that calculates the
The position where the trolley 8 meets the trolley 8 is automatically adjusted to the optimum position.

As described above, the container ship equipped with the container guide 19 is
During navigation, the container guide 19 is used to prevent the containers 3 loaded on the deck 2a from collapsing, but when unloading or loading the containers 3 after docking at the quay 4, which will serve as a container terminal. , the container guide 19
The shipboard container transfer device 20 is installed on the beams 23 and 24 of the shipboard container transfer device 20, and the container guide 19 is used as a travel guide for the shipboard container transfer device 20. A series of container cargo handling operations can be carried out in cooperation with the installed container crane 1.

Container cargo handling using the container transfer device 20,
An example of unloading from the container ship 2 to the chassis 18 on the quay 4 will be explained as follows.

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 located directly above the container 3 to be unloaded.

At this time, the relay container receiver stand 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, the spreader 28 is lowered to grip the container 3 loaded on the container ship 2. Next, as shown in Fig. 2, the spreader 28 is raised to pull up the container 3, and when the lower end of the container 3 reaches a position slightly above the relay container holder 29, the spreader 28 is raised. to stop.

Then, the relay container receiver runs one or both of the stand 29 and the main body frame 26, and the main body frame 26
The stand 29 of the relay container receiver is placed under the container 3 which is suspended inside.

Next, the spreader 28 is lowered and the container 3 that was being lifted is placed on the stand 29 of the relay container holder.Then, the grip by the spreader 28 is released, and the relay container holder moves the stand 29 onto the main body frame. 26.

Next, the spreader 9 suspended from the trolley 8 of the container crane I is lowered, and the container 3 placed on the relay container receiver is lifted up, and the rest is carried out in the same manner as before. The trolley 8 on the container crane 1 is run to lower the container 3 onto the chassis 18 on the quay, but in the meantime, the main body frame 26 and the relay container receiver stand 29 move on to the next cargo handling operation. That is, the main body frame 26 moves to the second container 3 by the same operation as described above.
is removed from the hull, while the relay container holder is placed on stand 2.
9 picks up the second container 3, then lowers the first container 3 onto the chassis 18, and moves it to the quay 4 side so that it can meet the trolley 8 of the container crane I returning earlier. run towards.

In this case, the position where the trolley 8 of the container crane I and the relay container receiver meet the stand 29 is the position of the chassis 18 on land, the position of the container 3 to be loaded next by the main body frame 26, and the position of the container 3 to be loaded at the current time. The optimum position of the trolley 8 and the relay container receiver is calculated based on the position of the stand 29, etc. so as to eliminate unnecessary waiting time.

Then, at the point where they met, the container crane 1's truck 15-lorry 8 and the relay container receiver stop the traveling of the platform 29, and the carrier passes the container 3 between them. The container crane I travels toward the main body frame 26 to pick up the third container 3, and the container crane I
Go to lower the second container 3 onto the chassis 18. Repeat the same steps below.

Incidentally, when loading the containers 3 from the quay onto the container ship 2, the trolley 8 of the container crane 1, the relay container receiver, the platform 29, etc. may be operated in the opposite manner to the above.

When cargo handling is carried out as described above, for the second and subsequent containers 3, the platform 29 and main body frame 26 of the relay container receiver run on the ship's hull, and the containers are transferred to the trolley 8 of the container crane 1. The traveling distance of the trolley 8 on the container crane 1 is reduced by the amount that the position where the container crane 3 is transferred approaches the quay.

In this case, the rate at which the traveling distance of the trolley 8 is reduced is
Since the auxiliary trolley is much larger than the conventional case where the auxiliary trolley is placed on the container crane, this greatly reduces the cycle time of the trolley 16 = -8 on the container crane 1, and reduces the work time and time required for container handling. It becomes possible to significantly reduce efficiency.

In addition, by erecting the container guide 19 on the deck 2a of a container ship and setting the container transfer device 20 on the container guide 19, it is possible to use a ship whose hull width exceeds the maximum width of the Panamax type. Even in cases where the container crane l cannot reach the range, the main body frame 26 and the relay container receiver can be moved on the platform 29, and even in the case of a ship with a very large hull width, the container transfer device 20 can be moved. It can be used effectively and the work and efficiency of container cargo handling can be significantly shortened.

In addition, in the container transfer device 20 described above, the main body frame 26 and the stand 29 of the relay container receiver are both installed on the container guide 19. In this case, the stand 29 of the relay container receiver is placed on the main body frame. Beam 24 below 26
Since it is attached to the spreader 28 of the main body frame 26
The vertical distance of the container 3 can be kept small, and as a result, the main body frame 26 and the relay container holder can be moved to the stand 2.
9, it is also possible to reduce the size of the main body frame 26 to promote the compactness of the equipment, and it is also possible to reduce the size of the main body frame 26 and promote the compactness of the equipment. Even if the gap in the height direction between the cell guide and the cell guide is small, the work can be carried out efficiently without any problems.

In the above-mentioned embodiment, the main body frame 26 and the relay container holder 29 are configured to run on rails, but it is also possible to use a trackless type that does not use rails, or a combination of a rack and pinion. etc. can also be used.

Furthermore, in the above-mentioned embodiment, the main body frame 26 of the container transfer device 20 and the stand 29 of the relay container holder were made to run on the beams 23 and 24 at different height positions, respectively. - As shown in FIG. 6, both may be made to run on the uppermost beam 23.

"Effects of the Invention" As is clear from the above explanation, a container ship equipped with a container guide according to the present invention uses the container guide to prevent containers loaded on the deck from falling over while sailing. When unloading or loading containers after docking at a quay that will become a container terminal, a shipboard container transfer device is installed on the beam of the container guide, and the container guide is used to transfer containers onboard. Used as a traveling guide for the equipment, it is possible to carry out a series of container cargo handling operations in conjunction with the ship's two-phase container transfer equipment and the container crane installed on the quay side.

In this case, the shipboard container transfer device may include, for example,
A main body frame that can run in the width direction of the hull between the pair of beams using a pair of beams installed in parallel at the same height position as a travel guide, and a container that is suspended from the main body frame so that it can be raised and lowered. If the container is configured to include a spreader or the like capable of suspending containers, container cargo handling on a container ship can be carried out entirely by the above-mentioned shipboard container transfer device.

Therefore, when handling containers between a container ship and a quay, the movement of containers by a container crane installed on the quay side is carried out between a container transport chassis waiting on the quay and the container transporter on the ship. The distance traveled by the container crane can be reduced by the distance traveled by the onboard container transfer device on the container ship. In this case, the rate at which the travel distance of the trolley on the container crane is reduced is much greater than in the conventional case of deploying an auxiliary trolley on the container crane. This will significantly reduce the time required, making it possible to significantly reduce container handling time and efficiency.

In addition, if the above-mentioned shipboard container transfer device is normally stored on the quay side and installed on the container guide on the container ship by a container crane when the container ship docks at the quay, it is possible to install the container ship's equipment on the container guide. Therefore, it is possible to use only a container guide as a simple structure, and it is also possible to reduce the cost required for the ship's equipment.

In addition, if a shipboard container transfer device is installed on the container guide as described above, and a series of cargo handling operations are performed by cooperation between the container crane and the shipboard container transfer device, the hull width can be reduced to Panamax. Even in the case of a ship exceeding the maximum value for its type, the above-mentioned shipboard container transfer equipment can be used to cover areas that the container crane cannot reach, and even in the case of a ship with a very large hull width, container handling operations and Efficiency can be significantly reduced.
