BACKGROUND OF THE INVENTION
The present invention relates to a mooring device for a floating pier.
[0002]
[Prior art]
As a mooring device for a floating pier, there is an invention of JP 2002-121705 A, for example. In addition, there is a chain mooring device. This chain mooring requires a large mooring area, but has the advantage of being economical and easy to relocate. For example, when it is moved to the disaster area and used urgently as a base for marine access at the time of an earthquake disaster, it is excellent in that it can be easily removed and reinstalled.

[0004]
[Problems to be solved by the invention]
However, the chain mooring device as described above requires a wide mooring area, so that it is difficult to use the water efficiently, and the floating bridge and the like are difficult to use in the vicinity of the structure because of the large amount of horizontal movement. was there.
[0005]
This invention is made | formed in view of the above problems, The objective is to provide the mooring apparatus for floating piers which can moor a floating pier efficiently, safely and stably.
[0006]
[Means for Solving the Problems]
The mooring device for a floating pier for solving the above problems is provided with an upper ring and a lower ring, which are connected to a mooring pile standing in the sea by a connecting tool, and can be moved up and down. The floating pier is connected and the upper ring has a float. In addition, the mooring piles are erected facing each other, and the upper rings facing each other are connected by a connecting material, and the connecting material includes a float installed. Further, it includes that a smooth material is provided on the inner side surfaces of the upper ring and the lower ring.
[0007]
Since the upper ring and the lower ring on which the float is installed move up and down together with the floating pier according to the change in tide level, the floating pier and the lower ring are always at the same level to suppress the horizontal movement of the floating pier.
[0008]
In addition, the wave force (horizontal force) of the floating bridge acts on the fixed part on the mooring pile side via the chain. Therefore, the fixed part is separated into an upper ring at the upper part of the sea and a lower ring at the lower part of the sea, and these are connected by a connector, thereby maintaining the function of the mooring device for the floating pier and having a degree of freedom. Can be.
[0009]
Further, by connecting the upper rings of the mooring piles opposed to each other and providing a float between them, only the buoyancy can be expected from the float, so that the size can be minimized.
[0010]
Moreover, since the friction with an upper ring, a lower ring, and a mooring pile is reduced with the smooth material provided in the inner surface, these vertical movements become easy.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a mooring device for a floating pier (hereinafter referred to as a mooring device) of the present invention will be described with reference to the drawings.
[0012]
The mooring device 1 is composed of a flat rectangular floating pier 2 and a pair of mooring piles 3 placed on both sides on the short side of the floating pier 2. Therefore, this floating pier 2 is in a state of being installed between the mooring piles 3 as shown in FIG.
[0013]
This mooring pile 3 is a set of two, and as shown in (1) of FIG. 3, an upper ring 4 and a lower ring 5 are installed in each mooring pile 3 so as to be movable up and down. It is connected by three chains 6 which are connecting tools.
[0014]
Further, on the inner side surfaces of the upper ring 4 and the lower ring 5, as shown in FIG. 3 (2), a smooth material 11 for reducing friction with the mooring pile 3, for example, a resin such as Teflon (registered trademark). You can also paste the material.
[0015]
Further, since the lower ring 5 moves freely with respect to the upper ring 4, that is, the vertical movement, horizontal movement and rotation are freely connected by the chain 6, the mooring chain 9 and the lower ring change slightly depending on the positional relationship with the floating pier 2. It is possible to easily cope with the direction of force to 5. Since the connection by the chain 6 can be easily adjusted in length at the site, it is possible to easily cope with a change in the structural scale (size) of the floating pier 2.
[0016]
The upper rings 4 of the mooring piles 3 facing each other are connected to each other by a connecting plate 7 that is a connecting material, and a float 8 is installed on the lower surface of the connecting plate 7. Therefore, the upper rings 4 and the lower ring 5 connected to the upper ring 4 by the chain 6 can move up and down according to a change in tide level.
[0017]
On the other hand, the lower ring 5 is installed at the same position as the lower surface of the floating pier 2, that is, at the same level, and is connected to the floating pier 2 by a mooring chain 9. Therefore, the lower ring 5 and the floating pier 2 are connected at the same level, and the mooring chain 9 is an efficient mooring that does not loosen.
[0018]
In addition, since the upper and lower rings 4 and 5 move up and down according to changes in the tide level, the distance from the floating pier 2 is always kept constant, so that the floating pier 2 collides with the mooring pile 3 and other structures. Without having to be in a safe mooring state.
[0019]
FIG. 5 shows another mooring device 10 in which a float 8 is installed on the upper surface of a connecting plate 7 which is a connecting material, and the other configuration is the same as that of the mooring device 1 described above. When the float 8 is thus installed on the upper surface of the connecting plate 7, the distance between the upper ring 4 and the lower ring 5 can be reduced.
[0020]
Further, the float 8 can be installed not only on the connecting plate 7 but only on the upper ring 4. In this case, it is not necessary to connect the upper ring 4 with the connecting plate 7, and the upper rings 4 are made independent from each other.
[0021]
FIG. 6 shows the case where the floating pier 2 is continuously moored. Usually, in the mooring method of a roller type using mooring piles, when mooring floating piers continuously, four mooring piles are required for each floating pier. However, in the case of the mooring device 1 of the present invention, if the mooring device 1 is provided between the floating piers 2, it can be used as the mooring device 1 for the floating piers 2 on both sides, so that the number of mooring piles 3 can be reduced. it can. In this case, as shown in the figure, a crossing plate 12 can be installed between the floating piers 2 on both sides.
[0022]
【The invention's effect】
An upper ring and a lower ring, which are installed on the mooring pile, are connected by a connecting tool, a floating bridge is connected to the lower ring, and a float is installed on the upper ring. Since the ring moves up and down together with the floating pier in response to changes in tide level, the floating pier and the lower ring are always at the same level to suppress horizontal movement of the floating pier, making the floating pier efficient, safe and stable. Can be moored.
[0023]
Since the wave force (horizontal force) of the floating pier works through the chain on the fixed part on the mooring pile side, this fixed part is separated into the upper ring in the sea and the lower ring in the sea. By connecting with a connector, the mooring device can be configured with a degree of freedom while maintaining its function.
[0024]
By connecting the upper rings of the mooring piles facing each other and providing a float between them, only the buoyancy can be expected from the float, so the size can be minimized.
