Description

[Detailed Description of the Invention] This invention relates to a device used for attaching a fender to a quay to prevent damage to a ship or a quay when a vessel approaches the quay.

Generally, some fenders are used by being attached to a quay. However, there are various shapes of quay walls, and for example, when installing a fender 4 on a quay wall 3 that has a space between the lower end of the side surface 1 of the quay wall and the sea surface 2 as shown in FIG. fender 4 at the lower end of
One end of the fender 4 was fixed, and the other end of the fender 4 was fixed to the tip of an H-shaped steel 6 whose base end was fixed to the support pile 5 supporting the rock wall 3. However, when the fender 4 is supported in this way, the fender 4
When a ship comes into contact with a ship, the H-shaped steel 6 rigidly supports the lower end of the fender 4, so if the impact force is large, the H-shaped steel 6 will be damaged and the fender 4 will no longer be able to perform its function. It was hot.

The purpose of this invention is to provide a support device for fenders that solves the above problems. Therefore, this invention has the first and second arms arranged in parallel, and the third and fourth arms arranged in parallel. In other words, the first to fourth arms are arranged to straddle the first and second arms, and the first to fourth arms form a parallelogram. An elastic body is provided between the joint part of the second arm and the joint part of the second and third arm,
A coupling device for the fender is provided at the coupling portion of the first arm, and a coupling device for the support body is provided at the coupling portion of the first and third arms.

With this configuration, when a ship contacts the fender, each arm is pulled off into a diamond shape by the impact force. At this time, the elastic body is stretched and the impact force is absorbed. After this impact force is absorbed, each arm returns to its original state due to the repulsive force of the elastic body. As described above, according to the support device of this invention, fenders can be installed even on quay walls where there is a space between the side of the quay and the water surface, and the support device will not be damaged even if an impact force is applied. This allows the fender to effectively perform its function.

This invention will be explained in detail below based on one embodiment shown in FIGS. 2 and 3. In FIG. 2, arms 10, 12, 14, and 16 are made of steel and have the same length, and each has a substantially U-shaped vertical cross-section. These arms 12 to 16 are combined to form each side of a square, and each intersection point is a bolt 18a, 18b, 1
8c and 18d.

A tensile member 20 is attached between the joints of arms 10 and 16 and the joints of arms 12 and 14. That is, one end of the tensile member 20 is inserted between the intersection of the arms 10 and 16 and fixed by a bolt 18a, and similarly, one end of the tensile member 20 is inserted between the intersection of the arms 14 and 12. The other end is inserted and fixed with a bolt 18b. As shown in FIG. 3, the tensile body 20 has a chain 24 in a relaxed state embedded in a rubber-like elastic body 22 formed in a cylindrical shape.

One end of a joint 26 is connected between the intersections of the arms 10 and 14 by a bolt 18c, and the other end of this joint 26 is connected to a semicircular metal fitting 28. 30 is a vertically movable pin of the joint 26;
2 is a movable pin in the same rotational direction, and this joint is rotatable around pins 30 and 32, respectively. The semicircular metal fitting 28 surrounds the cylindrical support pile 36 together with another semicircular metal fitting 34 of the same shape,
It supports arms 10 to 16. Numerals 38 and 38 are bolts for pressing and fixing the semicircular metal fittings 28 and 34. These joints 26 and semicircular fittings 28 and 34 constitute a coupling to the support pile 36.

A roughly L-shaped metal fitting 40 is fixed between the intersection of the arms 12 and 16 with a bolt 18d.
An elongated columnar fender (not shown) is attached to this metal fitting 40.
The lower end of is attached. Of course, the upper end of the fender is attached to the lower part of the side of the quay, similar to the fender 4 in FIG. 1. This metal fitting 40 becomes a coupling fitting for the fender.

In this support device, when a ship comes into contact with the fender attached to the metal fitting 40 and an impact force in the direction shown by the arrow 42 is applied, the arms 10 to 16 deform from a square to a diamond shape. At this time, the tensile body 20 is stretched and absorbs the impact force. At this time, even if the impact force is quite large, the chain 24, which is in a relaxed state, becomes tensed and receives the impact force, so the fender can fully perform its function without breaking the tension member. do. Further, when the impact force disappears, each arm 10 to 16 returns to its original state due to the repulsive force of the tensile member 20. Furthermore, since the joint 26 is used, even if a directional impact force is applied, each movable piston 3 of the joint 26
0 and 32, only the impact force in the direction shown by arrow 42 is applied to each arm 10 to 16. Furthermore, if a plurality of bolt insertion holes are formed in both ends of the tensile member 20 along the length direction, the positions through which the bolts 18a and 18b are inserted can be appropriately selected. Therefore, it is possible to cope with the situation at the site, that is, the difference in the distance from the support shaft 36 to the side of the quay.

In the above embodiment, this support device is used to support a columnar fender, but a large number of these support devices can be installed in parallel and used to support a plate-like fender. Further, although the tensile body 20 is used, a spring material such as a coil spring may be used instead.
