Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a container cradle such as a flat foam or a pallet used for cargo handling in a container yard.

[Conventional technology]

1. The loading and unloading form when the stacking cone 9 is attached and detached on the ground side by loading and unloading the container in the container yard.
Fig. 16 shows the cargo handling cycle.

1) Unloading cycle (when performed on the ground) ... Removing stacking cone 9 a) The containers 3 on the ship are vertically stacked as shown in FIG. Stacking cones 9 are inserted in the four corners between the upper and lower containers for lashing the upper and lower containers 3 as shown in FIG. First, a ship operator cuts the edge between the upper and lower containers 3 by rotating the handle 11 of the stacking cone 9. There are various methods for cutting the edges by using various stacking cones 9, and as an example, Fig. 17 shows the stacking cone 9 before cutting the edges of the upper and lower containers, and Fig. 18 shows the cut edges. A stacking cone 9 is shown. First, in FIG. 17, the latch 12 is in the locking position by the force of the spring, and the upper and lower containers 3 are completely locked. Onboard worker handles
Rotate 11 from the ship downwards using hook bar 14 etc. (Fig. 18). Then, the latch 12 is retracted and is housed in the stacking cone 9 as shown in FIG. 18 so as to come out above the notch portion of the upper corner metal fitting 10 of the container 3 below.

b) As shown in FIG. 15, the container crane 1 is hung by the spreader 6 using the upper corner metal fittings 10 of the container 3 with the edge cut off, and the container 3 with this stacking cone 9 is hoisted, traversed, Perform operations such as unwinding, bring it to an appropriate height above the ground, and stop temporarily. The container 3 remains suspended in the air.

c) Since the stacking cone 9 cannot be dropped on the trailer chassis 4 or on the ground if the stacking cone 9 is attached to the lower side of the container 3, the stacking cone 9 remains suspended by the container crane 1. It is necessary to remove it in the state of. The removing method differs depending on the various stacking cones 9, but one example is shown in FIG. First, a ground worker first pushes down the locking pin 13 and turns the stacking cone 9 main body to the right to pull it out from the lower corner metal fitting 8 of the container 3.

d) After that, when the container crane 1 is dropped onto the trailer chassis 4, the main trolley 5 is traversed, the trailer chassis 4 is aligned, and then the trailer chassis 4 is unwound and the container 3 is dropped. When the container 3 is sent to the rear yard by the straddle carrier 7, the stacking cone 9 may be taken down after the stacking cone 9 is taken and the container 3 may be dropped to the ground. After that, the main trolley 5 moves toward the ship to receive the next container as shown in FIG.

2) Unloading cycle (when carried out with the platform 15 on the horizontal member 17 of the container crane 1) ... Removing the stacking cone 9 a) The container 3 on the ship is operated by the ship operator as shown in Fig. 20. The edge between the upper and lower containers 3 is cut so that the container can be handled.

b) The container 1 with the stacking cone 9 is brought to a proper height on the platform 14 shown in Fig. 20 by hoisting, traversing and lowering as in the case of being performed on the ground, and then stopped temporarily. .

c) With the stacking cone 9 still attached, it is not possible to drop it on the platform forme 15, so it is necessary to remove it while the container crane 1 is suspended as in the case where it is carried out on the ground. On the horizontal member 17 or on the plate form
At 15, remove the stacking cone 9 and place it on a leveler as if it were done by an operator on the ground. As above, the work is performed at a high place, and the platform 15 itself does not have a function to drop the container to the ground, and it is necessary to traverse under the auxiliary trolley 16 next to it. A mechanism for taking out and removing the stacking cone 9 is also considered. In this case as well, the container 3 is still hung through the wire rope, and it is quite difficult in practice to know the position of the stacking cone 9 and take it automatically because the shake of the load easily occurs.

d) The container 3 from which the stacking cone 9 has been removed is dropped onto the plating worm 15. The container 3 is now out of the loading cycle of the main trolley 5 of the container crane 1. After that, the main trolley 5 goes to the ship as shown in FIG.
16 hangs container 3 on platform 15 on the ground.

3) Loading cycle (when carried out on the ground) ... Installation of stacking cone 9 a) After the container crane 1 grabs the container 3 and hoists it a little on the ground (there may also be traversing) and then temporarily stopped.

b) Attach the stacking cone 9 to the lower corner metal fitting 8 of the container 3 which is still suspended via the wire rope. An example of this is shown in FIG. When the handle 11 of the stacking cone 9 is locked as shown in FIG. 21 (a), the fixed side of the stacking cone 9 is inserted into the lower corner metal fitting 8 of the container (3) and turned counterclockwise so that the fixed side is locked. Become.

c) After mounting the stacking cone 9, the container 3 which has been temporarily stopped is wound up as shown in the cargo handling cycle 2 of FIG.
It is traversed, unrolled and loaded onto a ship.

4) Loading cycle (when carrying out with the platform 15 on the horizontal member 17 of the container crane 1) ... Attaching the stacking cone 9 a) As shown in Fig. 20, the container 3 to be loaded is a supplementary trolley.
It is raised from the ground at 16 and placed on Platfohm 15.

b) The main trolley 5 of the container crane 1 grabs the container 3 on the platform worm 15 and winds it up a little, then pauses.

c) The stacking cone 9 stored on the horizontal member 17 is attached to the lower corner metal fitting 8 of the container 3 which has been suspended through the wire rope in the same manner as when mounted on the ground. Since this work is work at a high place and is the same as dangerous work, there is no difference from the case where it is removed, so an automatic attachment mechanism is also considered, but it is removed because the container 3 is still hung through the wire rope. The same problem remains as in the case.

d) After the stacking cone 9 is mounted, the temporarily stopped container 3 is loaded into the ship in the same manner as when loading from the ground.

5) Until now, we have described one cycle of unloading and loading.
With respect to both the cycles for loading the cargo into the ship, the loading and unloading of the stacking cone 9 described so far is within the cargo handling cycle as shown in the cargo handling cycle of FIG.

2. Fig. 25 shows the cargo handling configuration when the stacking cone 9 is attached and detached on the upper side of the container for cargo handling in the container yard, and Fig. 26 shows the cargo handling cycle.

1) Unloading cycle: Removing stacking cone 9 Stacking cone 9 unloading the upper container 3 while racking between the container cranes stacked vertically as shown in Fig. 25. When it is done, it is left in the upper corner fittings 10 of the four corners of the lower container 3. The remaining stacking cone 9 is removed and collected by a worker on the container 3. It is desirable that the above-mentioned worker finishes the collecting work of the stacking cone 9 in the unloading cycle shown in FIG. 26, and if the collecting work is not finished, the waiting time of the container crane 1 may occur. . The work of removing the stacking cone 9 is not included in the unloading cycle of FIG. 26 (not shown).

2) Loading cycle: Attaching the stacking cone 9 Contrary to the unloading cycle, the upper corners of the four corners of the container 3 below the container 3 where the stored stacking cone 9 is about to be loaded next time. A worker attaches to the metal fitting 10.
The mounting work of the stacking cone 9 is not included in the loading cycle (not shown).

3) Unloading and loading cycle ... Detaching and mounting stacking cone 9 Collecting stacking cone 9 on container 3 stacked below container 3 that has been unloaded, and
The stacking cone 9 is mounted on the container 3 corresponding to the bottom of the container to be loaded next time. This collection and installation work is also unloaded and not included in the loading cycle (not shown).

4) The workers who perform the above-mentioned collection and installation work ride on the head block, which is the suspension of the container crane, and transfer to the container on board from the ground, which is extremely dangerous, and recently, on the deck of the ship. Since the containers are also loaded on the steps, work will be done at a height of at least 4 steps container height on the ship (8 feet x 4 steps ≈ 9.8M), so there will be a tendency for workers to avoid work on the container crane 3 onboard the ship. Yes There are many methods of leaving stacking cones in the lower corner metal parts (see item 1).

3. Despite the fact that the stacking cone is about 5 to 10 kg / piece, attachment and detachment are mainly done manually by workers. Recently, an automatic removal device has been considered, but the stacking cone is a wire. At present, it is quite difficult to detect load fluctuations because it is attached to the bottom of a container crane that is hung by ropes, and to detect the stacking cone position in three dimensions (hoisting, traverse, traveling direction of the crane). is there. Storage of stacking cones that have been manually or automatically attached / detached requires manual work such as throwing them into a container, and also the work of transporting them because the trailer chassis or straddle carrier, etc. is an obstacle to coming under the container crane. Work is hard.

[Problems to be Solved by the Invention]

1. The method of attaching and detaching the stacking cones on the container on board is the oldest method, and it is excellent in that it does not affect the loading and unloading cycle of the container crane. When it came to load containers, it became work at a high place, and there was a problem in terms of worker safety. In order to solve it, many methods have been used to attach and detach stacking cones on the ground side. The work is also performed while the container is suspended by the cargo handling device. Therefore, the loading and unloading time of the container crane is included in the loading and unloading cycle, resulting in loss time and new problems. (For example, modern container cranes that are planned to handle 50 containers per hour will need to load one container every 72 seconds. Lost time due to 15 seconds of loading and unloading is 20% of the loading cycle. %) 2. Furthermore, the main trolley 5 is an unloading container as shown in Fig. 25.
Temporarily place it on Plattform Ohm 15. Or vice versa
Plating foam 15 by supplementary trolley 16 for shipping container
In a system equipped to temporarily put
After temporarily placing the container 3 in the flat ohm 15 and before it is hoisted again,
If the stacking cone 9 can be attached and detached while the container 3 is temporarily placed in the stacker 15,
Detachment time does not cause a long cargo handling cycle.

Further, as shown in FIG. 27, the unloading container is temporarily placed from the main trolley 5 on the pallet 59 supported by the elevating device 58 for raising and lowering the pallet 59, or conversely, the pallet 59 placed on the ground is used for the loading container. In a system in which the container 3 is temporarily placed by another cargo handling machine, after the container 3 is temporarily placed on the pallet 59, the container 3 is temporarily placed on the pallet 59 until the container 3 is suspended again. If the stacking cone 9 is made detachable, the stacking cone attaching / detaching time does not cause a long cargo handling cycle.

The platform on which the container is placed, such as the platform 15 and the pallet 59, will be referred to as a container cradle.

The same effect can be obtained by placing a container pedestal on the ground and placing the container on it with appropriate cargo handling equipment such as a straddle carrier, and attaching and detaching the stacking cone 9 on this pedestal. You can get it.

3. Furthermore, if the stacking cone of the container is attached / detached on the container cradle, there is no shaking of the container due to the swing of the rope, which is the case when attaching / detaching the container while it is suspended, and the attachment / detachment work itself is easy. .

4. However, as shown in Fig. 29, the conventional container cradle 018 was designed to support the weight of the container at the position of the bottom corner fitting of the container, so that the container cradle 018
It was impossible to attach and detach the stacking cone unless it was grated or it was hung from the container cradle 018.

Therefore, if the weight of the container on the container cradle is supported by the wide part of the bottom surface of the container, excluding the lower corner metal fittings, the space corresponding to the lower corner metal fittings of the container pedestal is used for attaching and detaching the stacking cone. You can

5. An object of the present invention is to provide a container cradle for attaching / detaching a stacking cone while the container is placed on the ground, based on the technical idea of the above item 4.

[Means for Solving the Problems]

1. The container cradle is placed on the ground or on the horizontal material of the container crane, and the space is large enough to avoid hitting the lower container corner fittings and stacking cone with the lower container corner fittings and stacking cone. To provide. The weight of the container will be supported on the top surface of the cradle.

2. Using the void, attach or detach the stacking cone manually or automatically.

3. Allow the stacking cone to be stored and stored in the container cradle.

4. A moving device is installed on the container cradle to improve cargo handling efficiency.

[Work]

1. Since there is a gap, the container can be placed on the container cradle with the stacking cone attached. Therefore, since the container crane attaches and detaches the stacking cones, there is no loss time when the container is suspended and suspended.
In addition, since this container cradle is placed on the ground side (including on the horizontal material of the crane), dangerous work at high places that is performed on the container on board is eliminated.

2. Since it is possible to remove the stacking cone while the container is placed on the container cradle, it is safer than the stacking cone removal from the suspended container.
Even in the case of automatic attachment and detachment, the prevention of load shake and the detection of the stacking cone position are greatly simplified.

3. Since this container cradle has a storage and storage function, it is useful for reducing the fatigue of the worker who tried to store and store it, and if the automatic attachment / detachment device and the automatic storage device are combined, it is useful for the rationalization of the worker.

4. Furthermore, when this container cradle is placed on the horizontal material of the container crane, a moving device in the transverse direction of the container crane is added, so when combined with a supplementary trolley, the container cradle itself is a supplementary trolley. You can go down,
The cargo handling efficiency is higher than when the supplementary trolley only comes to the top of the fixed container pedestal.

Furthermore, when this container cradle is placed on the ground, a device that can freely move in the traversing and traveling directions of the container crane is added, so a crane or trailer for the fixed container cradle accompanying the hatch change etc. is added. The cargo handling efficiency is higher than that of moving by.

Figures 1,2,4,5,8,9 show various embodiments of the container cradle 18, and Figures 3,6,7,10,11 show various voids. The container cradle 18 includes a container lower corner fitting 8 and a stacking cone 9.
It has a void 19 large enough to avoid hitting.

FIG. 1 shows a first example of a container pedestal in which fixed voids 19 are provided in accordance with the respective lengths of containers to be handled.

FIG. 2 is a second example of the container cradle, which is the same as FIG. 1 in that a fixed gap 19 is provided in accordance with the length direction of the container to be handled, but the container is positioned in the traveling direction of the container. The upper surface is stepped in accordance with the length of the rails, the positioning guides 31 are provided at the peripheral edges, and the wheels 55 on the rails 56 are provided at the four corners. In this case, compared to receiving almost the entire bottom surface of each length container in FIG. 1, in the case of a 40 foot container, the 20 foot container portion 18a at the center has a gap between the bottom surface of the container and the container cradle, The 10-foot parts 18b and 18b on both sides of the container bear the weight of the container. In this way, it is not necessary to support the entire bottom surface of the container.

It is also possible to provide a positioning guide 31 for facilitating the placement of the container on the container pedestal in the lateral traveling direction of the container crane or in one of the lateral traveling directions. Again

A motor 26, a sprocket 27, and a sprocket chain 25 provided above are used to move the container pedestals 18, 18 closer to each other, move them away from each other, or move them in opposition to each other. A case is shown in which a notch-shaped void 19 that is aligned with the lower corner fitting 8 is provided. See P.25 * 5. The void 19 in the container cradle 18 shown in Fig. 1 and Fig. 2 was a fixed type void according to the length of each container.
The air gap 19 in FIGS. 5 and 5 is an example of a type in which the air gap 19 moves according to the length of the container on the container pedestal using power, and both are shown as an example of the above ground arrangement type.

FIGS. 3, 6, 7, 10 and 11 show examples in which the shape of the void 19 having a size large enough to avoid contact with the container lower corner fitting 8 and the stacking cone 9 is different. Fig. 3 shows a shape in which a hole is formed in a notched step from the upper surface of the cradle 18 in the middle part of the container cradle, and as shown in Fig. 7, there is a hole in the entire cradle 18 depth. You may open. FIG. 6 and FIG. 7 show the container pedestal 18 having four corners with holes of required depth or notched holes communicating vertically.

FIGS. 8 and 9 show still another ground-mounted container cradle 18
An example of is shown. When it is provided on the horizontal beam 17 in FIG. 20, the wheels and the driving device may be added to the pedestal as in the embodiment of FIG. The embodiment of FIG. 8 has a longitudinal rail on a lower base 72 having a length greater than the maximum container length handled.
24 is provided, and a pair of relatively small container pedestals 18, 18 on which the wheels 23 are movably mounted on the rail 24 are provided, and a pair is formed by the geared motor 26, the sprocket 27, and the sprocket chain provided on the lower table 72. The container pedestals 18, 18 are moved toward each other, away from each other, or opposed to each other. The pair of pedestals 18 and 18 are adjusted so that the lower corner metal fittings are 8 minutes shorter than the length of the container 3 to be handled, and the lower corner metal fittings 8 and 8 overhang from the ends of the pedestal 18 The container 3 is lowered and received, and in this state, the stacking cone 9 is attached and detached by forming a space 19 outside the end of the container pedestal 18 as a space 19. When installing the stacking cone automatic attachment / detachment device on this pedestal 18, 18, use the container pedestal 1
If four sets of devices are attached to the ends of the outer end faces of the 8,18, there is an advantage that this stacking cone automatic attachment / detachment device can be shared when handling containers 3 of any length. The storage space for the removed stacking cone 9, which will be described later, can be formed not only on the container pedestals 18, 18 but also in the lower pedestal 72. Further, when this type is arranged on the container crane machine, the wheels and the drive device may be attached to the lower part 72.

In the embodiment shown in FIG. 9, the lower corner metal fittings 8 of 45 feet container or less are provided with corresponding voids 19 similarly to the example of FIG. 1, and only the largest 48 containers are provided with the lower corner metal fittings 8 from both ends. It shows that it is received by overhanging, and the action and effect are substantially the same as the example of FIG.

FIGS. 8, 9 and 10 show the case where the container cradle is made shorter than the container used, and the entire end of the container cradle is used as a void. Although not shown in the drawing, a void may be formed by edging a portion of these notches with shaped steel or the like. Further, as shown in FIG. 11, a through-hole may be opened only in the direction in which the stacking cone enters.

The procedure and apparatus for attaching / detaching the stacking cone while the container is lowered on the container cradle shown in FIGS. 1, 2, 4, 5, 8 and 9 will be described below.

As shown in Fig. 17, the stacking cone 9 is sandwiched between the upper and lower containers, and the conventional stacking cone 9 receives the weight of the upper container 3 at the collar 32 of the stacking cone. In the present invention, the method of FIG. 3, FIG. 6, FIG.
As shown in FIG. 10 and FIG. 11, the collar 32 of the stacking cone 9 is in the space 19 and the weight of the upper container 3 is from the bottom surface of the container excluding the lower corner metal fitting 8 of the container 3. It is designed so that it can be received by touching the upper surface of the container cradle. Since the space 19 is wide enough to attach and detach the stacking cone 9, the stacking cone 9 can be attached or detached manually or automatically.

There are various methods for attaching and detaching the stacking cone 9, depending on the type of stacking cone, but the following method is generally available.

(B) Figure 19 shows the case of manual operation. First, a ground worker puts his / her hand in the space, pushes down the locking pin 13 downward, turns the stacking cone 9 main body to the right, pulls out from the lower corner metal fitting 8 of the container 3 and takes out from the space and stores it on the ground. When installing, with the handle 11 of the stacking cone 9 in the locked state shown in FIG. 21, insert the fixed side of the stacking cone 9 into the lower corner metal fitting 8 of the container 3 and turn it counterclockwise to the lower corner metal fitting 8. On the other hand, it becomes a lock state.

(B) Figure 12 shows the automatic case. Refer to P.21 * 1. In the figure, 71 is the body frame of the stacking cone automatic attachment / detachment device 70 mounted in the void 19 of the container cradle 18. The body frame 71 is either fixed in place within the cavity 19 or mounted so that it is somewhat free-floating for easy alignment with the cone of the container. The reference numeral 45 is vertically movably engaged with the main body frame 71 through a guide wheel 40 and a rotation stop slide plate 57 provided vertically on the peripheral surface, and is vertically connected to the main body frame 71 by a vertical cylinder 42. A driven lift seat 39 is pivotally engaged with a lift seat 45 via a swing bearing 36, and a horizontal swing cylinder 38 connected between the lift seat 45 and the lift seat 45 changes from a locked state to an unlocked state, for example.

The cargo handling efficiency is higher than in the case. In this case, a case where the drive device is placed on the container cradle and a case where the drive device is pulled by a wire rope are considered.

As shown in FIG. 4, when the tires 22 are arranged on the container cradle and can move on the ground, it is possible to quickly deal with the change of the hatch of the container crane. In this case as well, the drive system by self-power or other power does not matter.

〔The invention's effect〕

At the position corresponding to the position of the lower corner metal fittings of the container, there is a space with a shape that can accommodate the lower corner metal fittings and the stacking cone attached to the lower corner metal fittings. Can be placed,
The following effects are produced: 1. The stacking cone can be attached / detached outside the cargo handling cycle of the container crane (main trolley), which improves cargo handling efficiency.

2. Automatic attachment / detachment is very easy because it is attached and detached using the container cradle.

3. Because stocks are held nearby, it is very efficient.

4. By installing a moving device, it is possible to match the movement of the container crane and other related equipment.
