DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial Application Field] In container transportation, as container vessels are getting larger and faster, it is important to reduce the time required for container handling at ports and harbors.
The present invention relates to a new container handling facility including a container crane, a transport facility and a yard crane.

[0002]

2. Description of the Related Art Conventionally, container handling is carried out from a ship to land or from land to ship by a container crane, and has a capacity of about 30 containers per hour. For example, unloaded containers are received by a trailer under the crane, then transported to a container yard and unloaded by a transfer crane. Although some progress has been made in individual equipment such as container crane and transfer crane, the container handling system using these equipment is basically intermittent transportation and is limited to automation and high-speed cargo handling. There was a system configuration with.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of a cargo handling facility according to the present invention will be given, and then each step will be described in detail.

The cargo handling equipment according to the present invention comprises: (1) a container crane for hoisting a container loaded on a container ship and immediately transporting the container in a lateral direction by a traveling carriage.
Is transferred to a second horizontal transfer device, and then transferred to a second horizontal transfer device.
While the container is continuously delivered from the horizontal transport device of the above, it travels by itself and rolls up and down at a predetermined position with a yard crane to load and unload the container. is there.

A case where a container is landed from a container ship will be described below with reference to the drawings. In FIG. 1, 1 is a container ship, 2
Is a container crane. Unloading of the container C loaded on the under deck and on deck of the container ship 1 is performed by the container crane 2 installed on the quay 3 (FIG. 2).

The container crane 2 has a boom 4a which can be turned between a horizontal position (during cargo handling) and a rising position (a virtual line in FIG. 2) and is supported by an upper frame 10a. Boom 4a
Is provided with a trolley (a) 5 which can be moved in the horizontal direction, and only the hoisting and lowering of the container C from the container ship 1 is performed by the hoisting mechanism (a) 5 'mounted on the trolley (a). However, the traversing can be performed at the time of alignment in a no-load state.

Below the trolley (a) 5, there is provided a bogie rail girder 7a in which the bogie 6a can move laterally, and is provided vertically in parallel with the trolley rail. The bogie rail girder 7a can be moved up and down by girder elevating devices 8 provided at both ends of the boom 4a (hereinafter referred to as a first horizontal transfer device).

The rail girder 7a is guided up and down by a guide portion 11 (FIG. 7) provided on a leg 10b of the crane 2, thereby making it possible to shorten the winding distance by the trolley (a) 5. .

When the spreader 9 provided at the lower end of the trolley (a) 5 is lowered by the hoisting mechanism (a) 5 'and the container C is lifted by the spreader 9, the bogie 6a enters under the container C and the hoist 6a is lifted. The received container C is received (FIG. 4).

The bogie 6a on the bogie rail girder 7a, which has received the container C from the spreader 9, is horizontally transferred on the rail girder 7a, and is mounted on the leg 10b of the container crane 2 for transfer. It is transferred by a lifting platform 12 (FIG. 5) onto a fixed bogie rail girder 7b provided on the quayside machine.

The container crane 2 is opposed to the boom 4a and has a girder 4b on the quay side and a lower part of the girder 4b in parallel with a fixed bogie rail. A girder 7b is provided. The bogie rail girder 7b also has the bogie 6a circulating up and down similarly to the case of the bogie rail girder 7a which is movable up and down. That is, the lifter 13 is provided at one end of the bogie rail girder 7b.
At b, the other end circulates between the upper and lower rails by the lifting platform 12 (hereinafter referred to as a second horizontal transport device).

The bogie 6a circulates vertically between both ends of the bogie rail girder 7a and 7b. That is, the lift rail 13a is provided at the tip of the rail girder 7a by the lifter 13a from the bottom to the upper side. -Move to Da7b, lifter 13 at land side end
b circulates from top to bottom.

A transfer machine 14 supported by the girder 4b of the container crane 2 is provided at the end of the bogie rail girder 7b. A transfer trolley (b) 15 is provided in the transfer machine 14, whereby the container C on the truck 6a reaching the end of the truck rail girder 7b is lifted, and the yard-side transfer platform 16 is provided. A yard side bogie that runs on a bogie rail 17 provided above.
It can be transferred to 6b. The transfer machine 14 is also used when transferring the container C from the container yard to the container crane 2 side.

A yard crane 18 is provided between the yard side transfer frames 16 (FIG. 9). Two cranes 18 basically correspond to one unloader of the container crane 2, and transfer the container C to and from the jar. The empty cart is returned by the remaining crane of the pair of crane. When a yard is added, two yard crane 18 are added corresponding to the unloader. Yar farther than container crane 2
When loading and unloading containers on the yard, it is connected laterally to the yard crane 18 provided on the yard on the container crane 2 side, and traverses the yard on the front side to transfer the bogie to the horizontal transport system. Bogie rail 17
(FIG. 2).

FIGS. 11 and 12 show details of the yard crane 18. FIG. The guard 18 is provided with a girder 19 between the carriages 16. And trolley
The container C is suspended by the hoisting mechanism 21 which can be shifted at 20 and is stacked on the container yard.

Further, in order to further connect the yard crane 18, the link 22 as shown in FIG. 11 is tilted so that the left and right trolley rails are continuous.

[0019]

[Effects] 1) The trolley hoisting mechanism (a) 5 'provided on the boom of the container crane 2 performs only the hoisting and lowering of the container C, and does not carry the cargo in a horizontal direction. Of course, it has greatly contributed to the reduction of cycle time. 2) Since the horizontal transport is performed semi-continuously by the upper and lower circulating carts, efficient container handling becomes possible. 3) Since the rail girder can be moved up and down along the legs of the container crane 2, the hoisting and lowering distance of the trolley hoisting mechanism can be reduced. 4) Since a trolley (or conveyor) was used for transportation on the ground side, automation was facilitated. 5) Since the yard crane 18 was provided on the container yard, automatic cargo handling became possible. 6) As described above, automation can be performed in each step, and the container crane 2 and the rear equipment are integrated, so that the efficiency of the entire system is significantly higher than in the past.
