Description

[Detailed Description of the Invention] The present invention relates to a cargo handling method using a floating box,
In particular, a floating box is usually connected to land and used as a floating pier, and depending on the type of cargo handling, ballast water is injected into a ballast tank provided on the side opposite to the land of the floating box, and the floating pier is used to construct a ramp. , the vessel is placed on a guideway provided on the upper surface of the floating box, and the vessel is pulled onto land using a towing device, or the floating box is floated once and then pulled onto land using a towing device. This will enable the expansion of mooring facilities, the efficiency of cargo handling operations, and the efficient landing of ships.

In recent years, the demand for marine transportation has increased as the volume of goods has increased, and as a result, the absolute shortage of port facilities, such as the shortage of berths due to congestion of ships, has become a problem. A similar trend can be seen in fishing ports, where the increase in the number of fishing boats has resulted in a conspicuous lack of mooring facilities. As a result, the efficiency of cargo handling operations such as unloading of cargo and landing of fish catches is poor, and cargo handling operations often cannot be carried out due to waiting in line for mooring. Also,
In fishing villages that do not have a fishing port nearby, landing the catch is troublesome and difficult. Furthermore, in times of stormy weather such as typhoons, unloading of fishing boats is almost always done manually, and at present an excessive amount of labor is expended on these cargo handling operations.

On the other hand, since the construction of a fishing port requires a huge amount of money, these small and medium-sized fishing villages have conventionally tried to improve the efficiency of cargo handling by building simple piers. However, all of these conventional examples were pile-driving piers. Therefore, since the water level to the top of the pier varies depending on the tidal level difference,
The efficiency of cargo handling work from small fishing boats was poor, and it was not possible to contribute to the landing work of the fishing boats.

Furthermore, similar trends such as a shortage of port facilities have been seen overseas, and there has been a desire to develop a functional mooring and cargo handling method for installation and movement, especially for construction purposes, especially for temporary use. .

This inventor has come up with this invention in view of such problems.

In other words, the purpose of the present invention is to provide a jetty which normally functions as a pier during berthing and mooring, and which is particularly suitable for cargo handling in small vessels as it is not affected by the tidal difference, and which is suitable for cargo handling depending on the type of cargo handling. By forming a ramp with the floating boxes themselves that make up the floating pier, the floating boxes are used to allow easy, safe and efficient loading and unloading of small vessels such as fishing boats and yachts, as well as unloading of containers and materials. By providing a cargo handling method, a further object of the present invention is to provide a ship accommodation facility on land and accommodate small ships on land, thereby eliminating congestion in a port, increasing the capacity, and making the port more efficient. It is another object of the present invention to provide a cargo handling method using a floating body that can be used for various purposes.A further object of the present invention is to provide a cargo handling method using a floating body that can be easily installed and dismantled as a pier, and that can be set up and moved freely. A further object of the present invention is to provide a cargo handling method using a floating box that has a simple structure, can be safely and easily constructed, and provides an economical port facility. Our goal is to provide the following.

Therefore, the present invention forms the ballast tank 2 at the end of the floating box 1, and also forms the ballast tank 2 at the end of the floating box 1.
A guide path 4 for cargo handling is provided along the longitudinal direction,
A single floating box 1 or a connected body formed by connecting a plurality of floating boxes 1 by connecting the guide path 4 to the land 5
Depending on the type of cargo handling, ballast water is injected into the ballast tank 2 on the side opposite to land of the floating body 1 and the tip 7 of the floating pier 6 is lowered into the water. A slope is formed by the floating jetty 6, the cargo handling object 8 is placed on the guide path 4 of the upper surface 3 of the floating box 1 submerged in the water, and the cargo handling object 8 is pulled up to the land 5 by a towing device, or the cargo handling object 8 is pulled up to the land 5 by a towing device. After placing the object 8 on the upper surface 3 of the guideway 4, the floating box 1 is floated, the cargo handling object 8 is placed on the upper surface 3 of the floating jetty 6, and the object 8 is pulled up to the land 5 by a towing device. This is a cargo handling method using boxes.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Various materials such as concrete and steel plates can be used for the floating box 1, and various shapes such as cubic and cylindrical can be adopted, but due to the need for a pier, A rectangular shape is preferred. As shown in FIG. 1, the floating box 1 has a ballast tank 2 formed at its end. This ballast tank 2 may be formed only at one end of the floating box 1, or may be formed at both ends. Furthermore, the capacity of this ballast tank 2 is set to such an extent that the top surface of the floating box 1 will sink moderately from the water surface when ballast water is injected, and specifically, the capacity of the ballast tank 2 should be such that when ballast water is injected, the top surface of the floating box 1 will sink moderately from the water surface. The capacity is large enough to sink the floating box 1 to the extent that it can be placed on the top surface 3 of the box 1. The floating box is provided with a device (not shown) for injecting and discharging ballast water and an inlet/outlet (not shown).

Furthermore, a guide path 4 for cargo handling is provided on the upper surface 3 of the floating box 1 along the longitudinal direction. Here, the "longitudinal direction" refers to the direction from the sea side of the floating box 1 toward the land when the floating pier 6 is constructed by connecting the floating box 1 to the land 5. This is based on the fact that normally, piers are often formed to protrude toward the sea, and in particular are formed into a rectangular planar shape, with the short side facing the land and the long side protruding in the direction that intersects the land. It is. The guide path 4 can be of various types. The guide path 4 in the illustrated embodiment is constructed by arranging a plurality of roller sets in which two rollers 9 are arranged in the axial direction thereof in the longitudinal direction of the floating pier 6 made of the floating box 1. As shown in FIG. 3, this roller set is installed with a taper so that the inside of each roller 9 is lower and the outside is higher, and the taper is gradually tapered from the sea side of the floating pier 6 toward the land. It is preferable to configure the angle to be large. In addition to this embodiment, the guideway 4 may include wooden or steel rails laid in the longitudinal direction, sleepers arranged at appropriate intervals, or a cart with wheels or sleds. Various means can be adopted, such as installing a ship, placing the ship on this truck, and sliding the truck.

The floating box 1 having such a configuration is connected to land 5 to form a floating pier 6. In this case, the floating pier 6 is
The floating box 1 may be used alone, or the guide path 4 may be made continuous to form a connected body in which a plurality of floating boxes 1 are connected. In addition, when forming a connected body, there is no problem if the ballast tanks 2 are provided at both ends of the floating box 1, but if the ballast tank 2 is provided only at one end, each It is necessary to connect the floating box 1 with the ballast tank side and the anti-ballast tank side facing each other. Furthermore, the floating boxes 1 may be connected to each other by interposing a cushioning material 10 between the joint surfaces and tensioning the floating boxes 1 using a tensioning material (not shown) such as a coated steel wire.
Also, like a hinge, the upper parts of the joint surfaces of the floating boxes 1, 1 to be connected are each pivoted, and a cushioning material 10 is placed between the joint surfaces.
They may be connected so that they are interposed.

The floating box 1 can be used as a floating pier at all times as a mooring facility for various ships, and the relative level between the floating box 1 and the ship can always be kept constant, so it is particularly suitable for mooring small ships. It is possible to easily carry out cargo handling work or to get people on and off the small vessel.

This floating box 6 can also be used as a ramp depending on the type of cargo handling. That is, when the ship itself is unloaded, or when materials such as containers or wood are unloaded. To form a ramp with the floating pier 6, first activate the water filling device (not shown in the figure) built into the floating pier 1, and the tip of the floating pier 6 on the side opposite to the land sinks to an appropriate depth from the water surface. As you do,
Ballast water is injected into a ballast tank 2 provided on the opposite-to-land side of the floating box 1. In this case, the appropriate depth from the water surface is, for example, when a ship is to be unloaded as the cargo handling object 8, a depth that is slightly deeper than the stuttering water of the ship. The guide path 4 of the upper surface 3 of the floating box 1 submerged in the water in the slope formed by the floating pier 6
The ship, which is the cargo handling object 8, is rotated and placed there. Thereafter, the ship and a towing device (not shown) are connected with a wire or the like, and the towing device is activated to tow the ship. At this time, the roller set serving as the guide path 4 is provided in a tapered shape with the outer side being higher and the inner side being lower.
In addition, since the angle increases as the ship approaches land, the ship to be salvaged is automatically guided to the center of the guide path 4 as it is pulled by the towing device, and rolling of the ship is also prevented. By pulling further, the cargo can be unloaded onto land. In addition, although cargo can be unloaded with the slope formed as described above,
The cargo handling object 8 may be placed on the floating box 1 by floating the floating box 1, and then pulled by a traction device. In other words, the guide path 4 of the upper surface 3 of the floating box 1 that has sunk into the water
After that, the vessel carrying the cargo handling object 8 is placed around the ship, and then the floating box 1 is floated, the cargo handling object 8 is placed on the floating jetty 6, and the cargo handling object 8 is pulled by a towing device to the land 5.
It will be pulled up to. According to this, since there is less resistance when pulling the cargo, it is possible to carry out the cargo handling operation with a smaller output than the traction device required when unloading the cargo on the slope, making it possible to carry out cargo handling work more economically. In this case, it is preferable to connect the cargo handling object 8 and the traction device with a wire or the like before floating the floating box 1. This is to prevent the cargo handling object 8 from falling.

Furthermore, as shown in FIG. 4, a slipway 11 is provided so that the cargo handling object 8 can be moved laterally after being unloaded, and the cargo handling object 8 can be moved laterally using a winch (not shown) or the like. By accommodating or temporarily storing ships and the like in accommodation bases, congestion in ports can be alleviated and the ports can be used more effectively. This slipway 11 can be constructed using various means, such as a so-called trolley type structure in which the slipway 11 is moved by a trolley on laid rails. In addition, the floating box 1 forming the floating pier 6
The connection with land 5 such as a pier, seawall or coast is via a connecting bridge 12 as shown in Figures 1 and 4.
Free installation is possible by spanning the
In this case, since fluctuations in the water level can be taken care of by the connecting bridge 12, there is no overload acting on the connecting portion, and the connection can be made safely. Note that it is also necessary to arrange a roller set on the connecting bridge 12 so as to be continuous with the rollers 9 that form the guide path 4 provided on the floating box 1. Furthermore, the slipway 1
1, it is necessary to extend the guideway 4 to the vicinity of the slipway 11.

In addition, if this floating pier 6 is likely to be exposed to large waves due to a typhoon or tsunami, etc., a large amount of ballast water can be injected into the floating body 1 and the entire floating pier 6 can be sunk into the seabed. As a result, waves can be avoided and the floating pier 6 can be secured safely. In this case, it is necessary to form the ballast tank 2 with a larger capacity than that required to form the slope. By this means of depositing,
They can play an important role as safe mooring and cargo handling facilities even in places facing the open ocean without ports.

FIGS. 5 and 6 are explanatory diagrams showing a series of related states in FIGS. 1 to 4. FIG. 13 in the diagram
is a strip that connects the anchor (not shown) and the floating body 1.

In addition, since the buoyancy of the floating box 1 and the connected body formed by connecting a plurality of floating boxes 1 is determined by the conditions such as the material, size, structure, etc. of the floating box 1, it is necessary to incline the floating box 1 to form a ramp. In addition, the capacity of the ballast tank 2 and the amount of ballast water necessary for sinking to the seabed and raising the floating pier to form a floating pier are also determined by the conditions of the floating box 1. Therefore, based on this decision, the amount of ballast water injected and discharged from the floating body 1 is determined in advance for each usage mode of the floating pier, ramp, and subsidence, and a setting circuit for this is incorporated into the water injection and distribution pump, etc. By keeping the floating box 1 in place, it is possible to control the attitude of the floating box 1 for each mode of use just by operating a switch. For example, if the amount of water to be poured is set in the switch between the floating pier and the ramp, and the switch between the ramp and subsidence,
By setting a predetermined switch to each mode, the necessary amount of water is automatically poured into the ballast tank, and the attitude of the floating body 1 is controlled in the predetermined mode.

As described above, according to the present invention, it always functions as a pier for berthing, mooring, etc., and is especially suitable for cargo handling by small ships because it is not affected by the tidal level difference.
In addition, depending on the type of cargo handling, the floating jetty itself can form a ramp, making it easy, safe and efficient to handle various types of cargo such as fishing boats and materials. Furthermore, by establishing a ship accommodation facility on land and implementing this invention, congestion in the port can be eliminated and the capacity of the port can be greatly expanded.
The inside of the port can be used effectively. Furthermore, according to the present invention, it is easy to install and remove as a pier, it can be moved freely as a set, it can be safely ensured even when large waves act, and the structure is simple and safe. Moreover, it is possible to provide a cargo handling method using a floating box that can be easily constructed and provides an economical port facility.
