JPH0248295A - Wooden block for dock - Google Patents

Abstract

PURPOSE:To eliminate dent damage on ship bottom and to save the labor required for wooden block adjusting works by installing elastic containers containing non-compressive fluid like water on the base of wooden blocks, and uniformly supporting, with the entire surface of the elastic containers, the outer shell of the bottom of a ship entering a dock. CONSTITUTION:An elastic container 4 is rigidly fixed on the base 2 of a wooden block 1 with fixing members 3, and non-compressive fluid like water 8, oil or magnetic fluid is filled therein. The water 8 can be increased or decreased by means of a pipe 9 and a valve 10. A ship coming into a dock sits on and are supported by many wooden blocks. The elastic containers 4 then receive the load, and they adhere closely and uniformly to the shape of the ship bottom through the non-compressive, freely flowing water or the like filled therein. The water can be poured in or drained out through the pipe, making it possible to adjust its level, which eliminates the fear of dent damage to the ship bottom and saves the labor and time required for the arrangement and adjustment of wooden blocks to enhance the operating efficiency of the dock.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dock board for supporting a docked ship accommodated in a dock.More specifically, the present invention relates to a dock board that supports a docked ship accommodated in a dock. Regarding the installed dock board.

[Conventional technology]

Conventionally, docking boards for supporting docked ships are classified into fixed boards and automatic boards, and are further divided into keel boards and belly boards depending on the installation location.

The keel board that supports the bottom keel of a docked ship is usually a fixed board because the bottom keel part is often horizontal, and this supports most of the weight of the entire ship.

On the other hand, the belly wood that supports the parts other than the bottom keel supports the hull.
To provide additional support and at the same time to prevent the ship from rolling or rolling over, automatic boarding boards are used that can easily adjust the height.

In addition, in order to accommodate the bottoms of vessels with a small radius of curvature such as submersibles and those of specially shaped docked vessels, curved boards adapted to the shape of the bottom of each docked vessel are specially manufactured and used in each location.

[Problem that the invention seeks to solve]

However, with the above-mentioned conventional fixed board and automatic board, the support part of the bottom of the ship cannot be sufficiently tightly adjusted to the bottom of the docked ship in terms of fine adjustment of height, slope, and conformity of curved surface to the bottom of the ship. Achieving close contact requires a great deal of time and effort using specialized, advanced techniques. In other words, it is necessary to install a large number of various boards in series for a huge ship docked in a vast dock, and to ensure that all these boards support the bottom of the ship reliably and stably.
When you put it all together, it's extremely precise work.

In other words, regardless of whether any one of the many planks installed was higher or lower than the others, the uplifting force was concentrated on a local part of the hull, which caused the accident where the bottom of the ship collapsed. .

In addition, if the setting of the board is unstable or there is a thick rubber member on the edge of the board, the ship supported will sway due to the instability or elasticity, and this will be exacerbated. There was a risk that the load would be concentrated on the protruding part of the supporting board and cause a dent.

It is an object of the present invention to provide a board that can be easily and reliably installed and adapted to the bottom of a docked ship without the above-mentioned drawbacks.

[Means for solving problems]

This problem is solved by attaching an elastic container containing fluid to the main part of the board.

In other words, in order to adapt the upper part of the board to the shape and curved surface of the bottom of the ship, an elastic container containing a fluid, especially water, which is incompressible and can be fluidly deformed to freely change its shape and height, is used. be.

[Effect]

The elastic container is fixed by the mounting member provided on the base of the elastic container mounting board of this invention, and due to the incompressibility of the fluid contained therein and the freely flowing deformation amount, the elastic container contacts the bottom outer shell of the ship in dock. Therefore, the container can be given the most uniform supporting load and an excellent tight fitting shape.

The present invention will be described in detail below based on the drawings.

An elastic container 4 is fixed by a one-dimensional member 3 provided on a base 2 on a board l.

The elastic container 4 is made of compound rubber that has excellent weather resistance and seawater resistance, and reinforcing members such as steel wire 5 are used in its main parts, so that even if strong internal and external pressures act on the elastic container 4, the container remains intact. It is designed to prevent punctures. The shape of the elastic container 4 is usually rectangular, but it can be circular or any other shape.

Further, it is desirable that the surface 6 of the elastic container 4 has grooves 7 cut therein to prevent slipping, like the surface of an automobile tire. The grooves 7 of the elastic container 4 not only prevent it from sliding against the bottom of the ship, but also have a flexible surface that can accommodate solid foreign matter such as oysters attached to the bottom of the ship.

Bullet l/1: The container 4 is not limited to compounded rubber, and can also be made of synthetic resin or other materials if the usage conditions are met, but it is best to use the most proven tire material compounded with carbon black.

The elastic container 4 is filled with a fluid, in this case water 8 .

The fluid may be water, but seawater, oil, or other materials can be used depending on the purpose so as not to freeze in the winter or rot or boil in the summer.

The mounting member 3 firmly fixes the periphery of the elastic container 4 to the base 2. The base 2 has a pipe 9 and a valve 10, so that the amount of water 8 to be filled can be increased or decreased.

FIG. 2 shows an example in which the present invention is applied to an automatic board 11, in which the main body 14 slides and moves along the slope 13 of the base 12, and the hydraulic pressure from the outside is applied to the pipe 15. The height and position of the main body 14 of the automatic board 11 can be adjusted by moving the main body 14 up and down the slope of the base 12. The elastic container 16 is fixed onto the board body 14 by a mounting member 17.

The usage of fixed board and automatic board is the same as before.
The installation location, number, and adjustment are also done in the same way, but there is no need for fine adjustments that take a lot of effort.

When a ship enters a dock and drains the interior of the dock, the bottom of the ship is brought into contact with and supported on a number of various planks whose heights and positions have been adjusted by conventional methods, that is, on the dock planks of the present invention.

The elastic container loaded by the contact deforms to follow the shape of the ship's bottom due to the incompressible, freely flowing water that fills the container, and uniformly adheres to the ship's bottom. At this time, when water is individually injected or discharged from the pipes of the dock board to change the volume inside the elastic container, the elastic container swells or contracts because water is incompressible, and the height of the elastic container increases. You can freely adjust the height.

At this time, each board may be adjusted individually, but a predetermined number or all of the boards may be adjusted at the same time.

These operations can be performed remotely even when the hull and various boards are deep underwater, so there is no need to dry up the dock every time the ship enters the dock.

In the next embodiment, a magnetic fluid is used in place of the water contained inside the elastic container. Magnetic fluid has the property that magnetic metal powder is dispersed in a predetermined liquid and a magnetic field is applied when necessary to forcibly position the magnetic metal powder in the direction of the magnetic pole.The magnetic fluid, which is initially a fluid, gradually increases in viscosity due to the magnetic field. belongs to.

By applying a magnetic field, this docking board with built-in magnetic fluid increases its viscosity within the elastic container, solidifies while remaining deformed, and becomes a single hard board, forming a tight structure similar to that of a manufacturing board made by an expert. It can support the curved surface of the ship's bottom by closely contacting it.

Since the magnetic fluid is expensive, it is preferable to use it by incorporating it in a part of the elastic container in the shape of a keel in the curved direction of the curved surface of the ship's bottom, without filling the entire inside of the elastic container. Of course, the elastic container is equipped with a device for generating a magnetic field.

The composition of the magnetic fluid is preferably one that does not lose its properties as a magnetic fluid by separating its components and structure even under the high pressure generated within the elastic container.

In addition to the magnetic fluid, it is preferable to use a liquid or a liquid mixture that increases the viscosity of the internal fluid and crystallizes or solidifies when the internal pressure of the elastic container increases rapidly due to the load of the ship's hull.

Although the above description refers to a board that vertically supports the bottom of a ship, the elastic container is not limited to this and may also be used from the side or diagonally. [Effects] As explained above, the dock of the present invention Due to the use of the board, the surface of the elastic container on the board adheres uniformly and reliably to any curved surface of the bottom shell due to the incompressible flow deformation of the built-in water, and there is no risk of the fingers of the bottom shell. <Conventionally,
This reduces the amount of labor and time required to install and adjust the docks, and by controlling the liquid on the automatic board and the liquid inside the elastic container through pipes, remote control becomes easier, making it easier to operate the dock. This has the effect of increasing the rate and further reducing costs.
