Description

[Detailed explanation of the idea] [Technical field of invention] The present invention relates to an improvement of a fender device.

[Prior art]

In the first place, fenders are fixed or moored to quay structures in order to reduce the impact of ships berthing.

According to the results of the research conducted by the inventors of the present invention, the preferable points of the above-mentioned fender device are as follows. In other words, (a) both large and small ships can berth safely;

(b) During cargo handling, the distance between the ship's side and the quay can be made as narrow as possible to improve cargo handling efficiency.

(c) It is possible to berth even if the water depth near the quay is shallower than the required water depth due to fallen objects, sediments, ditches, etc.

(d) When the vessel becomes sluggish due to cargo handling, it must be possible to easily move the vessel offshore to prevent it from bottoming out.

However, the current situation is that no conventional fender device has been developed that satisfies each of the above points.

[Purpose of invention]

Therefore, an object of the present invention is to provide an excellent fender that can satisfy all of the above-mentioned favorable points as a fender.

[Structure of the idea]

That is, the present invention is constructed by arranging a plurality of fenders made of a rubber-like elastic body with a reinforcing layer embedded in them horizontally at intervals on the side aboard the structure, and among the fenders, the At least one pair of small-sized fenders with a low protruding height from the structure is provided next to each other, and a large-sized fender with a higher protruding height from the structure compared to this small-sized fender is provided. , the gist of the fender device is that the large fenders are installed at the left and right sides of the group of small fenders, and the large fenders are configured to allow air to enter and exit the airtight chamber. It is something to do.

〔Example〕

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

1 to 3 show a fender according to an embodiment of the present invention, FIG. 1 is an explanatory plan view, FIG. 2 is an enlarged side view with a part of the same cut away, and FIG. It is an enlarged explanatory view with a part cut away showing the essential part same as the above.

In the figure, E is a fender device consisting of an embodiment of the present invention, in which a plurality of fender members 100 made of a rubber-like elastic body in which a reinforcing layer K is embedded is attached to a structure G such as a quay.
The small fenders 110 having a low protruding height H from the structure G among the fenders 100 are arranged horizontally at intervals on the fender side Ga of the structure G, and at least A pair of small fenders 11 are provided.
0, the large fender 120 has a higher protrusion height H from the structure G than the small fender 11.
These large fenders 120 are attached to the left and right sides of Group 0, respectively, and are configured to allow air to enter and exit the airtight chamber A.

To further explain this structure, a small fender 1
fender 100 including fender 10 and large fender 120
As mentioned above, it is made of a rubber-like elastic body with a reinforcing layer K embedded therein, and as shown in the figure, it is formed into a bottomed cylindrical shape with an opening on the base side, that is, on the side where it is attached to the structure G such as a quay. A flange portion 101 is provided on this open side. A bottom plate 10 is provided on the outer surface of this flange portion 101 as shown in the figure.
2 by integrally attaching the airtight chamber A.
is formed.

In this embodiment, as shown in FIG. 3, this attachment means attaches the bottom plate 102 and the flange portion 101 to the free end side of the anchor bolt Gb buried in a structure G such as a quay, and attaches the nut Gc via the attachment plate 103.
It is detachable and integrally attached.

Further, the bottom plate 102 of the large fender 120 is provided with a ventilation hole 121, as shown in FIG.
2. It is connected to the supply/exhaust device 130 via the hose 123, union 124, adapter 125, etc.

In this embodiment, the supply/exhaust device 130 is composed of an exhaust valve 131, an air supply valve 132 communicating with an air supply device such as a compressor (not shown), a pressure gauge 133, etc., as shown in the figure. Accordingly, the air inside the large fender 120 can be exhausted or supplied.

In the above-mentioned embodiment, the small-sized fender 110 also has an airtight chamber A inside, similar to the large-sized fender 120, using a so-called pneumatic fender. In the case of the fender 110, it is of course possible to use a so-called solid type fender that does not have the airtight chamber A inside.

Furthermore, in this embodiment, an example was described in which a so-called fixed type fender, which is used by being fixed to a quay, etc., is used as the fender 100, but this is used by mooring to a quay, etc. and floating. Of course, a so-called floating type fender may also be used.

[Effect of idea]

Since the present invention is configured as described above,
When berthing a small ship, the air inside the large fender can be exhausted and the small fender can be used to safely berth. Air can be supplied and large fenders allow for safe berthing.

When loading cargo from a large ship that has come alongside the berth, the air inside the large fender is gradually exhausted, the ship is pulled toward the quay, and the small fender is placed alongside the ship. The distance between the two can be easily and safely reduced, and the workability of cargo handling can be greatly improved.

Furthermore, if the ship becomes swamped due to cargo handling, by gradually introducing air into the large fender again, the ship can be easily moved offshore and the ship will be able to reach the bottom. It can be prevented.

Furthermore, even in cases where the water depth near the quay is shallower than the required depth due to falling objects, sediment, or ditches, large ships can be berthed by using large fenders. be able to.

Therefore, the present invention (a) allows both large and small ships to dock safely.

(b) During cargo handling, the distance between the side and the quay can be easily narrowed, greatly improving the efficiency of cargo handling.

(c) It is possible to berth even if the water depth near the quay is shallower than the required water depth due to fallen objects, sediments, ditches, etc.

(d) When a ship becomes sluggish due to cargo handling, the ship can be easily moved offshore to prevent it from bottoming out.
