Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container storage device for a container.

[0002]

2. Description of the Related Art At present, containers are widely used for land and sea transportation as transport containers for the purpose of unitizing cargo, and accordingly, ships are located near ports which are points of contact for land and sea transportation. In order to efficiently transport containers by land in accordance with the arrival and departure of ports, it is desired to expand the standby area of the chassis on which the containers are mounted, but conventionally, the chassis is stored side by side on the ground. Was common.

[0003]

However, as described above, if the chassis are simply stored in parallel on the ground, there is a drawback that a vast land is required.

In view of the above situation, the present invention is to provide a container chassis storage device having a simple structure and capable of storing a large number of chassis in a limited space, and saving space.

[0005]

According to the present invention, there is provided a hangar standing upright on a pit, and a hangar which is connected to each other by a connecting member so as to be arranged in the hangar in the vertical direction with a required space therebetween. The present invention relates to a chassis storage device for a container, comprising a plurality of pallets that can be stacked and stored, and a pallet elevating device that is installed above the hangar and that suspends and supports the pallets so that the pallets can be hoisted and lowered. .

Further, the container chassis storage device may be provided with a pallet supply device for raising and lowering the uppermost pallet stacked and stored in the pit to the loading / unloading level.

According to the above means, the following effects can be obtained.

When carrying the chassis into the hangar, after placing the chassis on the uppermost pallet by the towing vehicle with the uppermost pallet positioned at the loading / unloading level,
Separate the chassis from the towing vehicle, wind the top pallet by the required amount by operating the pallet lifting device, raise the next pallet to the loading / unloading level, and place the chassis on each pallet in the same manner as above. To go.

On the other hand, when the chassis is carried out from the hangar, the towing vehicle is connected to the chassis placed on the pallet currently located at the loading / unloading level, and the chassis is towed by the towing vehicle. After emptying the pallet located at the loading / unloading level, the pallet elevating device operates to lower the required amount of the uppermost pallet, lower the empty pallet into the pit, and move it up one step. Then, the pallets are lowered to the loading / unloading level, and subsequently, the chassis placed on the pallets are sequentially pulled out by the towing vehicle in the same manner as described above.

Further, if a pallet supply device for raising and lowering the uppermost pallet stacked and stored in the pit to the loading / unloading level is provided, the alignment of the pallet with the loading / unloading level depends on the operation of the pallet lifting device. Instead, it can be done by operating the pallet feeder.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show an example of an embodiment of the present invention, in which a hangar 2 formed of a steel frame or the like is erected on a pit 1 and pallets are vertically arranged in multiple stages in the hangar 2. 3 and the pallets 3 which are vertically overlapped with each other are connected to each other by a connecting member 4 such as a chain, a wire, or a center-folding type link having a required length, and the uppermost pallet 3 is installed above the storage 2. The pallet lifting device 5 suspends and supports it via a wire rope 6 so that it can be hoisted down, and when the uppermost pallet 3 is unwound, the lower pallets 3 are sequentially stacked and stored in the pit 1. A container chassis storage device.

The pallet raising / lowering device 5 has a pinion 10 fitted on a drive shaft 9 rotatably driven by a motor 7 via a speed reducer 8, and a winch 11 around which a wire rope 6 is wound. Engage the integrated gear 12,
The wire rope 6 is fed from the winch 11 and wound around the fixed sheave 13, and the tip of the wire rope 6 is connected to the uppermost pallet 3. In the illustrated example, the winches 11 of the two adjacent container chassis storage devices are driven by the single motor 7. However, the winch 11 of each container chassis storage device is driven.
Needless to say, each may be driven by an individual motor 7.

Further, in the pit 1, there is installed a pallet supply device 14 for raising and lowering the uppermost pallet 3 stacked and stored in the pit 1 to the loading / unloading level. As shown in FIGS. 4 and 5, the pallet feeding device 14 includes a rod 1
5 A cylinder 17 having a sheave 16 pivotally attached to the tip thereof is erected, and the other end of a wire rope 18 having one end fixed in the pit 1 is hung around the sheave 16 to pallet 3 at the bottom stage.
The pallet 3 in the pit 1 is moved up and down by extending and retracting the rod 15 of the cylinder 17 so that the uppermost pallet 3 in the pit 1 is positioned at the loading / unloading level. ing.

Although a plurality of container chassis storage devices are arranged in parallel in the illustrated example, it goes without saying that only one container storage device may be provided.

Next, the operation of the illustrated example will be described.

When carrying the chassis 19 into the hangar 2, as shown in FIG. 4, a towing vehicle 20 (see FIG. 1) that pulls the chassis 19 is placed with the uppermost pallet 3 positioned at the loading / unloading level. After backing up and placing the chassis 19 on the uppermost pallet 3, the outriggers 21 of the chassis 19 are grounded on the uppermost pallet 3, the chassis 19 is separated from the towing vehicle 20, and the pallet lifting device 5 operates. The uppermost pallet 3 is wound up by a required amount, and the next pallet 3, that is, the uppermost pallet 3 in the pit 1 is moved to the cylinder 17 of the pallet feeder 14.
By the extension operation of, raise to the loading and unloading level,
Similarly to the above, the chassis 19 are placed on each pallet 3 sequentially.

On the other hand, when the chassis 19 is to be carried out from the hangar 2, the towing vehicle 20 is connected to the chassis 19 placed on the pallet 3 currently located at the loading / unloading level, and the chassis 19 is moved. After the outrigger 21 is contracted and the chassis 19 is towed by the towing vehicle 20 to empty the pallet 3 located at the loading / unloading level, the empty pallet 3 is moved to the cylinder 17 of the pallet feeder 14.
Of the pallet 3 from which the chassis 19 has been carried out by lowering the top pallet 3 by a required amount by the operation of the pallet elevating device 5 while lowering the pallet from the loading / unloading level by one pallet. 3 is lowered to the loading / unloading level, and thereafter, the chassis 19 placed on each pallet 3 are sequentially pulled by the towing vehicle 20 and carried out in the same manner as described above.

When the chassis 19 having a container (not shown) mounted therein is carried into the storage case 2, the pallet 3 is used.
If the length of the connecting member 4 for connecting the spaces is set in advance, or if necessary, the connecting member 4 is added each time to increase the height between the pallets 3. Good. If the height between the pallets 3 is set to a height that allows the towing vehicle 20 to pass through,
Instead of backing the towing vehicle 20 when the chassis 19 is loaded into the hangar 2, the towing vehicle 20 can be moved forward to pass over the pallet 3 and the chassis 19 can be placed on the pallet 3.

Thus, with a simple structure, a large number of chassis 19 can be stored in a limited space, and space can be saved.

The container chassis storage device of the present invention is not limited to the above-mentioned illustrated examples, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0022]

As described above, according to the container chassis storage device of the present invention, it is possible to store a large number of chassis in a limited space with a simple structure, and it is possible to save space. Can play.
