[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically attaching and detaching a stack of cones for stacking containers on decks of a ship and a container crane equipped with this apparatus.

[0002]

2. Description of the Related Art When stacking containers on deck of a ship in multiple stages, stack cones are used by fitting to upper and lower container corner fittings to prevent collapse of the container. The stacking of the stack cone to and from the container is performed manually by a worker when the container is lifted up or loaded and the container is supported by a container crane near the ground.

[0003]

Since each stack cone has a weight of 7 to 8 kg, the manual installation and removal is a heavy labor and dangerous. For this reason, attempts have been made to do this by mechanical operation, but it has not been put to practical use because the range of combined use of mechanical power and human power cannot be eliminated. (Actual development 6
4-1198).

9 to 12 show that the inventor of the present invention has applied the application No. 02-0.
This is a money receiving unit for automatic attachment / detachment disclosed in 04298. A lower receiving member 102 is attached to a supporting member 101 attached to a pedestal 100 by a motor 103 so as to be capable of reversing around a shaft 104, and the operating cylinder 10 is mounted on the lower receiving member 102.
9 and 10 are for an integral stack cone in which the cone and the seat are integrated, and Figs. 11 and 12 are swivel stack cones in which the cone swivels with respect to the pedestal. To indicate Insert the stack cone of the container onto the receiving unit and rotate the upper receiving member 106 by the operating cylinder to allow the container to escape (Figs. 10 and 12). Return the upper receiving member 106 as shown in Figs. 9 and 11.
The money receiving unit is reversed by the motor 103 as shown by the arrow, and the cone is dropped by its own weight into the lower cone receiving box. Even in this case, there remains a problem that manual work is required when setting the cone in the receiving unit in order to remove the cone from the receiving box and attach it to the container.

[0005]

[Means for Solving the Problems] The present invention is to automate the locking and unlocking of stack cones to the container by the receiving unit described above, and at the same time, to attach and detach the cone to the receiving unit and to transport the cone to the receiving unit and the storage place. The object is to provide automation and to provide a container crane having such a function.

In order to achieve this object, in the present invention, on the container pedestal, there are provided four cone receiving metal unit units each comprising a stacking lower cone fitting of the container and a stackable stacking cone seat and an operating cylinder for turning the stack. , A plurality of cone accommodating seats provided in the longitudinal direction of the cradle adjacent to the cone receiving metal unit, and a cone which can be automatically attached and detached between the cone accommodating seat and the cone receiving metal unit so that the cone can be freely attached and removed. And a cone carrier.

Further, the container cradle having the above-mentioned equipment is provided on the body of the container crane so that the stack cone can be attached to and detached from the container efficiently and efficiently on the machine to enhance the efficiency of the cargo handling cycle.

[0008]

[Operation] When the containers stacked with the deck are lifted up, the container with the stack cone hung on the spreader of the container crane is temporarily placed on the cradle. The lower cone of the stack cone goes into the cone seat of the receiving unit, the cone is swiveled to the position where it can be removed from the container by the simultaneous movement of the operating cylinder for swiveling, and the container is lifted on the cradle leaving the stack cone on the ground. Or it is dropped onto the container chassis. The cone receiving member unit is swung back to the lower cone disengageable position by simultaneous reverse operation of the stack cone swivel device. The cone transport device that waits freely for elevation can be activated, and the cone coupling part can be raised and run, coupled with the cone on the cone receiving unit, pulling out the cone upwards, and running backwards to freely adjust the cone storage seat. Insert the cone from above, release the cone, return to the waiting position, and wait for the next container to arrive on the cradle. When the container is loaded, the cone is transferred from the receiving seat to the cone receiving unit by the transport device and returned to the waiting position, and the cone swivel device is swiveled to the position where the cone can be inserted into the container and lifted from the ground. The container is temporarily placed on the cradle, and the cones are rocked to the container by simultaneous reverse operation of the cone turning device, and the container is hoisted and loaded by the spreader.
