Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container terminal device for transferring containers between a container yard near a quay and a container ship docked at a shore.

“Conventional technology” Conventionally, a container terminal device that transfers a container between a container yard near a quay and a docked container ship, for example, reciprocates a container suspension trolley between the container ship and the quay on the quay. A container crane that moves and a yard crane that reciprocates other trolleys in the container yard are provided so that they can run in parallel by mutually parallel rails along the quay, and a chassis that transfers containers is provided between both cranes. It has been configured. Then, for example, in the case of unloading work, the container crane transfers the containers one by one from the container ship to the chassis on the quay, and the chassis transfers the containers to the yard crane installation position. After that, it is transferred to a designated place in the container yard by a yard crane.

"Problems to be solved by the invention" However, with such a container terminal device, for example, when the trolley of the container crane after transferring the container to the chassis transfers the next container, the chassis becomes empty. If not prepared in the state of
Containers cannot be handed over, and the trolley needs to be on standby until the chassis returns. Therefore, in order to improve the efficiency of cargo handling work, it is necessary to devise to shorten the waiting time of the trolley and chassis of both cranes as much as possible, but the container loading position of each container ship and container yard is the cargo handling of one container. With each change, the time required for the trolley to make one reciprocation in both cranes also changes, so that it becomes necessary to adjust the position of the chassis for each cargo handling of the container, and the cargo handling work tends to be complicated. In this case, it is conceivable to improve the efficiency by increasing the traveling speed of each trolley and the chassis, but there is a limit in design, and it is likely to cause a load collapse.

The present invention effectively solves the above problems, and an object of the present invention is to provide a container terminal device in which each container can freely transfer containers regardless of their mutual positions to improve the efficiency of cargo handling work. .

"Means for Solving Problems" The present invention is provided so that a part of a girder supporting a trolley in both cranes is provided so as to vertically overlap with each other, and a girder between the cranes is provided below the overlapping position. An ice transport path for transporting the container while sliding the container is provided in parallel with the rail supporting the crane, and the ice transport path includes an ice track on which the container is placed directly and an ice track of the ice track. The propelling roller is arranged at a plurality of positions spaced apart from each other in the lengthwise direction, and pushes the container forward by rotating while contacting the surface of the container.

[Operation] The container terminal device of the present invention is a yard crane in which the container is transferred by a container crane and directly placed on the ice track of the ice transport path, while the ice transport path slides the container along the ice track. In the receiving position from the container crane, immediately after the container is sent out, the container is emptied and ready to receive the container. Further, by controlling the drive of the propelling roller, it is possible to adjust the transfer section, direction, transport speed, etc. of the container.

[Embodiment] An embodiment of the container terminal device of the present invention will be described below with reference to the drawings.

Also in this container terminal device 1, a container crane 5 that reciprocates the trolley 4 between the container ship 3 and the quay 2 on the quay 2, and a yard crane 8 that reciprocates another trolley 7 in the container yard 6 The point that parallel rails 9 and 10 along the quay 2 are provided so as to be able to run in parallel is the same as in the conventional example, but in both cranes 5 and 8, the trolleys 4 and 7 are used.
Part of the girders 11 and 12 supporting the upper and lower parts overlap each other vertically, and an ice conveying path 14 for transferring the container 13 between the cranes 5 and 8 is provided below the overlapping part. Are different from each other.

The on-ice transportation path 14 is parallel to the rails 9 and 10 that movably support both cranes 5 and 8, and the rails 9 and 1 are parallel to each other.
There are two strips of substantially the same length as 0, and each of the on-ice transport paths 14 is a pair of ice tracks 15 on which both sides of the container 13 are placed, respectively.
Container 1 by rotating while contacting the lower surface of 3
It is composed of a propelling roller 16 for pushing the container 3 forward, guides 17 for guiding both sides of the container 13, and a stopper 18 for stopping the container 13 at a desired position.

As shown in FIG. 3, each ice track 15 lays a refrigerating pipe 20 in a groove 19 formed in the ground in parallel with the rails 9 and 10, and water is supplied to fill the groove 19. The ice 21 is formed by freezing water while inserting a cooling material such as Freon into the freezing pipe 20.

The propelling roller 16 is disposed in the recess 22 formed between the ice-made orbits 15 in the container 13 in the longitudinal direction of the ice-made orbits 15.
A plurality of drive motors (not shown) are provided separately from each other at intervals of about 20 feet.

The guide 17 is provided on the outer side of the ice-making orbits 15, and long brackets 23 along the ice-making orbits 15 are erected so as to be opposed to each other via the ice-making orbits 15. A plurality of rollers 2 spaced apart from each other in the length direction.
4 is rotatably provided, and the rollers 24 are in contact with both side surfaces of the container 13.

A plurality of stoppers 18 are supported above the ice track 15 by a pedestal (not shown) at intervals of about the length of the container 13 so as to be arranged between the propelling rollers 16, for example. In general, the stop plate 25 is evacuated from the surface of the ice track 15 at a distance equal to or higher than the height of the container 13 and is projected downward when the container 13 is stopped. There is.

In the example of FIG. 1, two container cranes 5 and two yard cranes 8 are also provided.
In the figure, reference numeral 26 denotes a container gripping spreader suspended on the trolleys 4 and 7.

In the container terminal device 1 configured as described above, a case where cargo handling work is performed on the docked container ship 3 will be described. In this loading and unloading work, out of the two cranes 5.8 each provided with two sets, both cranes 5.8 shown in A of FIG. 1 are for unloading, and both cranes 5.8 are shown for loading. Shall be used separately.

First, the cranes 5 and 8 are arranged as shown in FIG. 1, and are arranged below the girders 11 and 12 of the unloading container crane 5 and the loading yard crane 8 in the ice transportation path 14. The other propelling rollers 16 are driven in the same direction to bring them into an operating state, and are arranged below the girders 11 and 12 of the unloading yard crane 8 and the loading container crane 5. The stopper 18 is kept in operation. Then, as shown by the arrows in FIG. 1, the containers 13 are transferred one by one by the trolleys 4 and 7 of the unloading container crane 5 and the loading yard crane 8, respectively, and the girder 11.
From the end of No. 2, hang on the ice transport path 14,
After being placed on the propelling roller 16 whose operation is stopped, the propelling roller 16 is put into an operating state and the container 13 is conveyed along the on-ice conveying path 14 while sliding on the ice track 15. When the container 13 is transported on the ice transport path 14, the container 13 is stopped at the position of the stopper 18 which is in an activated state, is transferred to the respective cranes 5 and 8, and is transported to a target container loading position. . In this case, the operation of the propelling roller 16 at the position for receiving the container 13 from the cranes 5 and 8 is stopped every time one container 13 is sent out, and the next container 13 transferred by each crane 5 and 8 is transferred. It is made to wait to receive.

Then, according to the loading position of the container 13 that changes as the cargo handling work progresses, the cranes 5.8 are moved to the rails 9.1.
0 along with shifting the position, and also select the propelling roller 16 at the position for receiving the container 13 from the cranes 5 and 8 and the stopper 18 to be activated according to the movement of the cranes 5 and 8. Is done.

In other words, the container terminal device 1 transfers the container 13 between the cranes 5 and 8 by the on-ice transport path 14 from the cranes 5 and 8 to the container 13.
At the position where the container 13 is received, the propelling roller 16 is operated only when the container 13 is received, the container 13 is conveyed by another propelling roller 16, and the standby state is maintained so that the container 13 can be received at any time. Further, the transported container 13 can be held at a required position by a stopper 18 and transferred to another crane. Therefore, the work can be effectively performed without waiting the trolleys 4 and 7 of both cranes 5 and 8.

Further, since the container is directly placed on an ice track and is conveyed by applying a propulsive force by a propelling roller, a carrier vehicle such as a carriage is unnecessary, and as a result, an empty carriage after the transportation is completed. It is possible to omit the time required to return the container from the container crane to the loading position and to continuously perform the cargo handling work without hindering the transportation of other containers.

Further, in such cargo handling work, the ice track 15 is
When the surface of the ice 21 is thawed, a lubricating action occurs when the container 13 is slid, and the container 13 can be smoothly transported. In this case, an underlay of synthetic resin or the like may be placed on the container 13 for smoothing.

As the cargo handling work progresses, the positions of both cranes 5 and 8 can also be moved. However, even on the ice transport path 14, the plurality of propelling rollers 16 and stoppers 18 are spaced by a length corresponding to one container. Since the on-ice transportation path 14 is divided into blocks according to the length of the container 13, the driving of the propulsion roller 16 corresponding to the position where the cargo handling has already ended is stopped, Only the propulsion roller 16 can be operated while operating,
It is possible to save energy. Of course, when the container 13 is placed at the front position in the transport direction, in order to avoid collision of the container 13, it is possible to perform control such as activating the stopper 18 in front of the container 18, and In the model diagrams of FIGS. 5 (a) to 5 (c), as shown by the arrows in the container transfer path, the driving direction of each propulsion roller, the transport section on the ice track, etc. are appropriately selected to select an arbitrary form. The cargo handling work of can be carried out.

The stopper 18 may be provided in each block, or may be movable so that it can be fixed at a necessary position. In addition, the ice-carrying path 14 is configured so that both cranes 5 and 8 can partially overlap the girders 11 and 12 within the span range of the container crane 5 (between the rails 9 in FIG. 1 and the like). It may be provided within the span of the container crane 5. Further, the propulsion roller 16 may be provided at the position where the propulsion roller 16 is provided instead of the roller 24 in the guide 17 of the embodiment, and the detailed configuration of the present invention is not limited to the embodiment. .

"Effects of the Invention" As described above, the container terminal device of the present invention has the following effects.

(i) An ice transport path was provided to transfer the container between the container crane and the yard crane, and the container was placed directly on the ice track and transported while sliding along the ice track. Therefore, if the container is received from the crane in the on-ice transportation path, the container is immediately transported and the transfer position with the crane is always on standby in an empty state, and an empty trolley or the like does not require a transportation vehicle such as a trolley. The time required to return to the delivery position can be omitted, the crane can be prevented from standing by, and the efficiency of cargo handling work can be improved.

(ii) By controlling the drive of each propulsion roller on the ice transportation path, it is easy to adjust the transportation section, direction, transportation speed, etc. of the container, and it is possible to handle cargo handling work of any form and necessary for cargo handling. Get only the part that is in operation,
It is possible to save energy.

(iii) By arranging a plurality of on-ice transportation paths, it is possible to improve work efficiency without interfering with other cargo-handling operations even in a plurality of cargo-handling operations in which the transfer routes overlap. Circulation operation, distribution operation, backup operation, etc. are possible, and various cargo handling work modes can be realized.
