[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reciprocates between a ship docked on a quay and the berth to transfer the container in order to unload the container loaded on the ship or to load the container from the berth. The present invention relates to a container crane, in particular, a continuous container crane capable of continuously transferring containers in a short cycle.

[0002]

2. Description of the Related Art An example of a container crane for unloading a container loaded on a ship docked on a quay to a land or loading a container loaded on a ship from a land to a ship is shown in FIG. Conventionally used.

As shown in the figure, such a container crane 18 has a rear surface shape in the traveling direction, as will be understood from FIGS. 3, 7, and 10 which will be described later, which is an embodiment of the present invention. In addition, the U-shaped structural member is provided, and the traveling device 20a is provided at the lower ends of the front and rear ends, and the sea-side U-shaped leg 1 arranged on the sea side of the quay 5 and the land arranged on the land side. The side U-shaped leg 2 and the bridge-shaped traveling leg 4 which are connected by a horizontal leg beam 3 and travel on the track 6 by a traveling device 20a that rides on the track 6 laid along the quay 5. Above this bridge-shaped traveling leg 4, a main girder 7 horizontally installed from the land side toward the sea side and supported, and a spreader 9 that travels on the main girder 7 and holds the container 10 are hoisted. The lifting device 8 is configured to be lifted and lowered by a rope and to be hung and transferred. In the figure, 11 is a container ship docked on the quay, and 12 is a trailer chassis that is pulled to the ground inside the bridge-shaped traveling legs 4 to transfer the container 10 to the ground.

In such a container crane 18, for example, when unloading the container 10, the spreader 9 of the hoisting device 8 holds the containers 10 on the container ship 11 one by one, hoists them, and moves them by the arrow 13. The container 10 is transferred along the path and loaded on the trailer chassis 12 on the ground. Further, the loading operation for loading the container 10 on land into the container ship 11 is performed in the reverse manner to the above-mentioned procedure.

Further, another example of the conventionally used container crane is shown in FIG. In this container crane 18 ', the sea-side U-shaped leg 1 of the bridge-shaped traveling leg 4 is used.
And the container yard 14 and the container 10 are hung on the leg horizontal beam 3 that connects the land-side U-shaped leg 2 to the leg horizontal beam 3
An auxiliary hoisting device 15 for traveling above is provided, and the hoisting device 8 described above provided on the main girder 7 is used to move the container 1 on the ship 11.
0 is conveyed to the container storage area 14 along the movement path 1 indicated by the arrow 16, and the auxiliary auxiliary lifting device 15 moves the container 10 on the container storage area 14 along the movement path 2 indicated by the arrow 17 to the ground. Container unloading work is carried out in the manner that the container is transported to the trailer chassis 12. Further, as in the case of the container crane 18 shown in FIG. 16, the loading work of the container 10 from the land to the container ship 11 is performed in the reverse order of the above work procedure.

As described above, when the container crane 18 shown in FIG. 16 unloads and loads the container 10, it is necessary to reciprocate the container 10 from the top of the container ship 11 to the ground with a single lifting device 8. Since the traveling distance of the hoisting device 8 and the vertical height of the spreader 9 are large, it takes a long time for one unloading and loading (hereinafter collectively referred to as unloading) cycle, and it is difficult to shorten the unloading time. There is a problem that is.

Therefore, the container crane 18 'shown in FIG. 17 has been improved and used to solve this problem. However, this container crane 1
8, the lifting device 8 and the auxiliary lifting device 15
In order to carry out two stages of simultaneous transportation with
There is an advantage that the unloading cycle of the hoisting device 8 is slightly shortened and the unloading time is shortened.

However, this container crane 1
8'has a problem caused by the unloading cycle times of the lifting device 8 side on the main girder 7 and the auxiliary lifting device 15 side not matching. In particular, when the auxiliary lifting device 15 side delays the transportation cycle due to the arrival of the trailer chassis 12 or the like, the lifting device 8 causes the lifting device 8 to move to the container storage area 14.
Then, a so-called time waiting occurs, waiting for the container 10 to be placed on a vacant place, and the carrying capacity of the lifting device 8 cannot be exhibited, resulting in wasting time.

[0009] The same reason occurs in the container crane 18 shown in Fig. 16 due to the arrival of the trailer chassis 12 or the like, but in particular, in order to shorten the unloading cycle, the container storage area 14 is set up. A newly installed auxiliary lifting device 15 is provided outside the lifting device 8 as shown in FIG.
In the container crane 18 'shown in (1), the improvement of the bending angle becomes a problem that the effect cannot be exhibited.
