Abstract

PURPOSE:To increase a cargo working efficiency by providing a container delivery table on a ship side, providing a crane for the cargo working between a container hold and said delivery table on an upper deck, and simultaneously using said crane with a land crane. CONSTITUTION:A container delivery table 5 is provided on the upper part of the ship side 4 of a hull 1 while a traveling gantry crane 3 is provided on a deck 2. A cargo working operation is carried out between a container hold 8 and the delivery table 5 using the trolley 6 and spreader 7 of the crane 3. An operation between the delivery table 5 and a quay wall is carried out by means of a land crane 9. And, by simultaneously using the crane on the deck with the crane on the land, the cargo working operation can be carried out with high efficiency. At the same time, since the crane on the deck can be operated only between the inside of the hold and the ship side delivery table, the cost of the crane can be lowered.

Description

[Detailed description of the invention] [Industrial application field] The present invention is provided on the deck of a ship for loading containers,
This relates to a shipboard crane that transfers containers to and from land-based cranes.

[Prior Art] An example of a conventional shipboard crane for handling containers will be described with reference to FIG. 5. A is a ship hull, b is a shipboard crane such as a gantry crane, and C is a quay.

Conventionally, a container e was moved between a container loading dock d of a ship body a and a quay C by a shipboard crane b.

[Problems to be Solved by the Invention] Conventionally, container cargo handling on ships involved loading and unloading containers e between the container loading dock d and the quay C using one shipboard crane b. , cargo handling efficiency does not improve, and even if there is a land crane on quay C, there is movement of the ship a, so even if automation is attempted with a land crane, there is a problem with positioning accuracy, and both ship crane B and land crane There was no attempt to make use of it.

The present invention enables cargo handling efficiency to be improved by having an onboard crane handle cargo handling between the container loading area of a ship and the ship side, and a land crane handling cargo handling between the ship side and land. The purpose is to provide a shipboard crane with a

[Means for Solving the Problems] The present invention provides a method for transporting containers between a container delivery stand provided on the side of a ship, a container loading hold provided on the deck of the ship, and a container delivery stand. It is a shipboard crane equipped with a crane and.

[Function] The onboard crane no longer needs to extend the transport distance to shore, and containers only need to be transported between the container loading area of the ship and the ship's side, so even if the ship is wide, Container cargo handling can be carried out efficiently.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In Figures 1 and 2, a crane 3 such as a traveling gantry crane is installed on the deck 2 of the hull 1. It is possible to travel in the longitudinal direction of the hull 1 along running rails (not shown).

A fixed or foldable container delivery stand 5 is attached above the ship side 4 of the hull 1. In the illustrated embodiment, a traveling gantry crane is used as the crane 3, and the container delivery platform 5 is attached to a leg of the traveling gantry crane and positioned above the ship's side 4.

A trolley 6 and a spreader 7 for grasping containers are provided on the crane 3 to transport containers (not shown) between the container loading bay 8 of the hull 1 and the container delivery platform 5. Containers are transported between the container delivery platform 5 and the quay by a land crane 9 installed on the quay.

As shown in FIG. 3, a distance sensor 10 is attached to the trolley 6, and a visual sensor 11 is attached to a part of the girder of the crane 3. The distance sensor IO measures the distance to the loaded container, and inputs the cross section of the loaded container on board at each point to the programmable controller 12 shown in FIG. 4. Visually, the sensor 11 determines whether there is a container or not and whether the container is in a fixed position on the container delivery table 5 by image pattern recognition, inputs the information to the programmable controller 12 shown in FIG. 4, and automatically operates the crane 3. be carried out safely and reliably.

A sensor 13 connected to the programmable controller 12 prepares encoders and the like for hoisting, traversing, and running the trolley 6, detects the positions of the crane 3 and the spreader 7 with respect to the hull l, and inputs the detected positions to the programmable controller 12. It is supposed to be done. A shipboard crane drive unit 14 is connected to the programmable controller 12, and is capable of hoisting, traversing,
Each motor 15 for traveling is controlled.

The programmable controller 12 includes a cable reel 16, a flexible fiber cable 17, and a connection box 1.
8 to the onboard computer 20 of the onboard control station 19. The onboard computer 20 has a keyboard 21 and a character display 2.
2. A floppy disk 23 for storing data and a printer 24 are connected.

As mentioned above, when the distance measuring sensor 10 shown in FIG. If the contents are different, correct the data in the onboard computer 20. Based on the corrected data, the speed pattern of the crane 3 for each container is automatically determined by the programmable controller 12. The cargo handling order of the crane 3 is input in advance into the onboard computer 20, and the container cargo handling operations between the container loading hold 8 and the container delivery platform 5 are carried out in order according to the operation start command. There is no operator's cab on top of the crane 3, and the system is such that the crane is normally operated completely unmanned, but in an emergency it can be operated manually by radio.

The onboard computer 20 is connected to a host computer 29 of a shore control station 28 via a junction box 25, a flexible fiber cable 26, and a connector 27. The host computer 29 has a keyboard 30. Character display 31, floppy disk 3 for storing data
2. A printer 33 is installed. The host computer 29 is connected to a programmable controller 37 of the land crane 9 via a connection box 34, a flexible fiber cable 35, and a cable reel 36. A sensor 38 and a local control box 39 are attached to the programmable controller 37, and each motor 4 for hoisting, traversing, and traveling of the land crane is connected via a crane drive unit 40.
1 is controlled.

When loading a container onto the container delivery platform 5 from the container loading hold, when a command to start operation is given to the onboard convenitor 20, the crane 3 travels to a predetermined position according to the cargo handling order entered in advance, and the trolley 6 and stop directly above the container to be carried out.

Next, the spreader 7 is lowered to grab the container, and the visual sensor 11 checks whether there is a container on the container delivery table 5. If there is a vacant space on the container delivery table 5, the spreader 7 Lift up the container you grabbed,
After placing the container on the container delivery table 5, the trolley 6 leaves.

When the trolley 6 has moved out and the spreader 42 of the land crane 9 no longer interferes with the trolley 6, the host computer 29 causes the spreader 42 to grab the container on the container delivery platform 5, lift it up, and transport it to land. do.

When loading containers into the ship's hull, perform the procedure in reverse order.

[Effects of the Invention] In the present invention, the crane installed on the deck of the ship only needs to move the container between the inside of the ship and the side of the ship, and there is no need to move the container to the outside of the ship. It is inexpensive and requires only a lane, and cargo handling efficiency can be increased by using a crane on deck and a crane on land at the same time.Even if the ship is wide, a normal land crane can be used, and a land crane can be used. Containers are transferred between the container and the crane on the deck on the container transfer platform, which has the effect of facilitating automation of cargo handling.
