It is movably supported along and is locked at a predetermined position.

Reference numeral 29 denotes a vertical shaft type hydraulic cylinder which is rotatably supported by a vertical shaft hinge 32 on the side wall of the quay within a range of ± 90 °, and has a ramp lift 33 for lifting the lamp 4 at its upper end. It is projected. Reference numeral 34 is a hydraulic cylinder for raising and lowering the hull standing upright in a plurality of pits 35 which are recessed symmetrically on the underwater shelf of the quay 5, and at the upper end of which a rest 36 that abuts the bottom plate of the container ship is projected. It is set up. The container ship bottoms by ballasting when it comes to berth, and its upper deck is at the same level as the upper surface of the quay. At that time, fine adjustment of the upper deck level is performed by the ballasting and hydraulic cylinders 34 for raising and lowering the hull.

When loading a container on a container ship in such an apparatus, as shown in FIGS.
The main body frame 4 is first on the quay, and the containers 2 carried from the container yard by the truck 8 are unloaded on the conveyor 7 and moved by the crane 6, where the work of stacking vertically is repeated.

In this way, the pair of upper and lower containers 2 stacked in two stages are sequentially transferred to the main body frame 4 by the conveyor 7.
Left and right pair of lift forks 10 at the bottom of the pedestal at the entrance opening of
Are sequentially fed over and the main body frame 4 is filled with the conveyor. Here, due to the power of the engine 5, the lift fork 10 that rises via the shaft 9 and the vertical chain 13 _V causes the container rows to be supported by the lift forks 10 at a position that is slightly elevated from the upper surface of the conveyor 7 at the same time. Frame 4 is in this state,
Along the long container frames 3 and 3 laid on the upper deck of the container ship across the ramp 4 by a large number of driving tires 16 that are driven simultaneously by the output of the engine 5 via shafts, chains, sprockets, etc. Moving. Here, the upper surface of the container base 3 is at a level slightly higher than the upper surface of the container 7.

[0015]
At that time, when the mark position sensors 19 and 19 respectively arranged at the lower front and rear ends of the body frame 4 detect the markings 20 imprinted on the long pallet racks 3 and 3, the driving tire 14 is operated by the computer 15. Stop all at once. Then, when the lift forks 10 are simultaneously lowered, all the containers in the main body frame 4 are simultaneously lowered and supported by the container base 3, and if the containers are fixed to the upper deck, the loading work is substantially completed. Therefore, the main body frame is returned to the original position and the loading work is completed. For the container unloading work from the container ship, the above-mentioned work procedure at the time of loading shall be performed in reverse order. In addition,
Since the driving tire in the above-described embodiment is rotatable in the angle range of 90 °, the main body frame can not only move forward and backward, but also turn left, turn right, and turn on the spot if necessary. It is possible to move a wide container yard vertically and horizontally.

[0016]

According to such a device, the following effects can be obtained. (1) During loading and unloading, the container ship bottoms out, its upper deck, ramp and quay upper surface are on the same plane, and there is no level fluctuation of the upper deck due to tidal waves, wind waves, etc., and stable and safe cargo handling work is possible. It can be carried out. (2) Since a large number of containers are loaded at one time by the multi-straddle carrier, the loading time can be shortened. (3) Since the starting and stopping and control of the multi-straddle carrier are automated, the loading and unloading of containers is labor-saving and labor-saving. (4) Most of this equipment is quayside equipment, and only a container mount is attached to the container ship itself, and since the container mount is relatively lightweight, it causes almost all the weight increase of the container ship. Instead, a large amount of goods can be loaded at high speed. (5) When the clearance between the container ship and the quay is small, the multi-straddle carrier can also cross this gap, and in this case, the ramp is unnecessary.

In short, according to the present invention, a long container is provided side by side on the upper deck of a container ship which has a small amount of water and berths on the quay, and then lands on the shore, and the horizontal upper deck is at substantially the same level as the upper surface of the quay. A plurality of pairs of parallel container supports that extend to the full width of the ship at a longitudinal interval that is approximately equal to the overall length of the container, and a plurality of vertical containers arranged vertically and horizontally at a longitudinal interval that is slightly longer than the overall length of the elongated container and at a prescribed lateral interval. 3D lattice-shaped frame body in which the upper parts of the columns are connected to each other by vertical beams and horizontal beams, drive tires attached to the lower ends of the columns to move the frame body laterally, and the frame body Horizontal conveyors for moving containers attached to the lower ends of the horizontal spaces that are partitioned from each other by the laterally arranged pedestals, and the lower ends of the opposite pedestals on both sides of each horizontal space. And a multi-straddle carrier movable in the lateral direction, which includes a lift fork that is arranged opposite to each other and abuts on the lower corners of both ends in the longitudinal direction of the same lengthwise container to raise and lower the container all at once. As a result, an economical container loading / unloading device capable of safely and quickly loading labor and labor on a large amount of containers on the quay and saving labor and labor is obtained. Therefore, the present invention is extremely useful industrially. ..
