(57) [Summary] (Modified) [Problem] A method for unloading and unloading large cargo such as container cranes safely and efficiently using hull buoyancy by injecting and discharging ballast water. I will provide a. SOLUTION: Ballast water of a carrier 1 provided with a ballast tank 25 and having a pair of arms 2 and 3 protruding from the hull end toward the bow direction is poured and drained, and ballast water is poured. The unloading and unloading of large cargo 6 is performed using the hull buoyancy of the drainage.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for unloading and discharging large cargo such as a container crane on a quay by utilizing the buoyancy of the hull by injecting and discharging ballast water.

[0002]

2. Description of the Related Art Conventionally, the following methods have been used for transporting large cargo such as a container crane by a barge or other carrier. In other words, large cargo such as container cranes cannot be loaded and unloaded onto carriers using quay cranes, so they must be disassembled into smaller structures before transportation, loaded, and assembled on land after transportation.

[0003] A method in which a long temporary rail is installed on a carrier ship approaching from the quay near the quay, and then large-sized cargo is loaded and unloaded by a cargo handling winch and a cargo handling line.

[0004]

However, the former method has a problem in that the large-sized cargo is once disassembled and then reassembled, requiring a great deal of labor and time for disassembly and assembly. On the other hand, in the latter case,
In addition to the need for ancillary equipment such as temporary rails, the work of installing and removing the temporary rails and the like by a large crane ship requires a great deal of effort and time.

The present invention has been made in view of the above-mentioned conventional problems, and safely and efficiently unloads large cargo such as container cranes by utilizing the buoyancy of the hull by filling and discharging ballast water. An object of the present invention is to provide a method for unloading and discharging large cargo.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a carrier having a ballast tank and a pair of arms protruding from the end of the hull toward the bow. This is a method of discharging and discharging large cargo by injecting and discharging ballast water and utilizing the buoyancy of the hull by the injection and discharge of ballast water.

Large cargo on quay (container crane, etc.)
After inserting a pair of arm members projecting toward the bow and stern from the hull ends, the ballast water in the ballast tank of the carrier is discharged, the buoyancy of the hull increases, and large cargo is discharged by the pair of arm members. it can. On the other hand, injecting ballast water into the ballast tank reduces the buoyancy of the hull,
The large cargo supported by the pair of arm members can be unloaded on the quay.

Further, a large cargo on the skid rail can be moved to a predetermined position on the skid rail by using a skid rail extending from the pair of arms to the carrier and a cargo winch installed on the carrier.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, the barge 1 as a carrier has a body 21 having a U-shaped cross section. Then, as shown in FIG.
The pair of left and right fork structures 2 project rearward from the stern 23 so as to be positioned on an extension (not shown) of the fork 22. An outrigger device 3 is attached to a rear end of each fork structure 2.

Further, the barge 1 has a pair of left and right skid rails 4. Each skid rail 4 has a barge 1
From the side wall 22 to the fork structure 2. A skid rail 4 is also laid on the outrigger device 3. In this example, the outrigger device 3 is attached to the tip of each fork structure portion 2. However, if only the length of the fork structure portion 2 is sufficient, the outrigger device 3 may be removed.

On the other hand, in the barge 1, a ballast tank 2 is provided.
The buoyancy of the barge 1 can be increased or decreased by injecting and discharging ballast water into and from the ballast tank 25. A pair of right and left cargo handling winches 5 are installed at the bow 24 of the barge 1. Next, a method of unloading a large cargo (container crane) using a barge will be described. (A) Method of unloading container crane As shown in FIG.
Then, the stern portion 23 of the barge 1 full of ballast water is made to approach the quay 8 so that the outrigger device 3 is located below the sliding bracket 7 attached to the container crane 6 on the cargo handling quay 8.

When the ballast water in the ballast tank 25 of the barge 1 is discharged, the buoyancy of the barge 1 increases, and FIG.
As shown in (b), the container crane 6 is lifted from the quay rail 9 of the quay 8 by the fork structure 2 and the outrigger device 3. As shown in FIG.
After the loading rope 10 of the loading winch 5 installed at the bow 24 of the barge 1 is attached to the front leg of the container crane 6, the outrigger device 3, the fork structure 2 and the barge 1 The container crane 6 is moved to a predetermined position on the barge 1 using the skid rail 4.

When the container crane 6 moves to a predetermined position on the barge 1 as shown in FIG. 5 (b), the container coon 6 is fixed to the barge 1 and the loading rope 10 is removed. (B) Unloading method of container crane As shown in FIG.
After approaching the stern 23 of the container crane 8, the loading rope 10 pulled out from the loading winch 5 is folded back by the pulley 11 attached to the rear end of the fork structure 2 and attached to the front leg of the container crane 6.

Next, while winding up the cargo handling cable 10, FIG.
As shown in (b), the container crane 6 is moved onto the fork structure 2 and the outrigger device 3. When ballast water is injected into the ballast tank 25, FIG.
As shown in (c), the buoyancy of the barge 1 is reduced, and the container crane 6 stands on the quay rail 9 of the quay 8.

In the above description, the case where the fork structure 2 is provided on the stern 23 of the barge 1 has been described. However, even if the fork structure 2 is provided on the bow 24 of the barge 1, large-sized cargo such as a container crane can be used. Can carry out unloading. Further, a self-propelled ship may be used instead of the barge.

[0016]

As described above, the present invention fills and discharges ballast water of a carrier having a ballast tank and a pair of arms protruding from the hull end toward the bow. In addition, since large-sized cargo is unloaded and lifted by utilizing the buoyancy of the hull by injecting and discharging ballast water, auxiliary equipment such as temporary rails and a large-sized crane ship for lifting temporary rails are not required. In addition to improving cargo handling efficiency and operation efficiency, cargo handling work can be performed safely and easily.

Further, a large cargo on the skid rail can be moved to a predetermined position on the skid rail by using a skid rail extending from the pair of arms to the carrier and a cargo winch installed on the carrier.
