The cell type fender utilizing the elasticity of rubber as described above has a reaction force characteristic as shown in FIG. In other words, the reaction force P changes proportionally to the displacement D of the floating body 1 when the wave height is low, resulting in a "proportional reaction force characteristic". When the wave height is high, the reaction force P becomes a constant value regardless of the displacement D of the floating body 1. Floating body 1 and steel pipe pile 9
To prevent an excessive load from being applied to the motor. Therefore, in order to cope with a higher wave height, the range of the constant reaction force portion must be enlarged (point D is set large), and for that purpose, the size of the cell type fender needs to be increased. However, since the cell type fender is an integrated rubber product, there is a problem that an increase in the size of the cell type fender causes an increase in cost. The present invention is intended to solve such a problem.

FIG. 11 is a side view of a floating mooring device according to an embodiment.
It is a side view of a floating body mooring device as an embodiment. In addition,
1 to 11 indicate substantially the same members or technical contents.

First, a first embodiment will be described with reference to FIGS. In the first embodiment, as shown in FIG. 1, a large number of eye plates 1a are protruded at appropriate intervals around the upper surface of the floating body 1, and each end of the mooring wire 2 of the hull 1 is provided on each eye plate 1a. The part is bound. The direction of the wire 2 is changed by a pulley 3, and a weight 5 is attached to a proximal end portion of the wire 2 via a spring 4.

The pulley 3 is rotatably supported on the upper end of a pulley support leg 7, and the pulley support leg 7 is vertically supported by a pedestal 6 attached to a steel pipe pile 9 erected on the sea floor. I have. The pulley support leg 7 is formed of a hollow cylinder as shown in FIG. 2, and a guide plate 6 that forms a guide portion for the weight 5 together with one inner wall 7 a of the cylinder is provided inside the cylinder. .

A stopper 8 for the weight 5 is provided at a position closer to the upper side inside the pulley support leg 7 of the cylindrical body. At the center of the stopper 8, an opening 8a for passing the wire 2 and the spring 4 is formed.

In the above configuration, when the load of the wire 2 fluctuates when the floating body 1 swings up and down, and when the vertical swinging of the floating body 1 is small (low wave height: first area), FIG.
As shown in FIG. 5, the spring 4 expands and contracts while the weight 5 is seated on the pedestal 6, and the expansion and contraction of the spring 4 suppresses the swing of the floating body 1.

Therefore, in the first region, the reaction force characteristic of the mooring device becomes "proportional reaction force characteristic". In this first region, the spring 4 corresponds to the fender 02 in the prior art.

When the wave height is high (second region), the spring elasticity of the spring 4 exceeds the weight of the weight 5, and the weight 5 is lifted upward away from the pedestal 6, and the weight is increased according to the vertical swing of the floating body 1. 5 moves up and down. In the second area, the swing of the floating body 1 is suppressed by the vertical movement of the weight 5. Since the spring 4 is rigid in the second region, the reaction force characteristics of the device are "constant reaction force characteristics". In this second area, the weights 5 correspond to the prior art fender 03 and chain 04.

In the third region where the waves are higher, the weight 5 is received by the stopper 8, so that the spring 4 expands and contracts in accordance with the vertical swing of the floating body 1. In the third region, the swing of the floating body 1 is suppressed by the expansion and contraction of the spring 4. Therefore, in the third region, the reaction force characteristic of the device is “(second) proportional reaction force characteristic”.

Thus, the first embodiment has the following features.
A structure in which a “constant reaction force characteristic” area is obtained by moving the weight 5 in the vertical direction in accordance with the vertical swing of the floating body 1 in the second area while having a reaction force characteristic similar to the conventional one. Therefore, the weight of the weight 5 is increased, or the stroke (the distance until the weight 5 separates from the pedestal 6 and comes into contact with the stopper 8) is increased, so that the constant reaction force characteristic area of the apparatus (the reaction force in FIG. The distance between the point P and the point D in the characteristic graph can be lengthened.

Further, by selecting the spring constant of the spring 4, the proportional constant (the position of the point P) in the proportional reaction force characteristic can be arbitrarily set. Needless to say, the device shown in FIG. 2 is provided on each of a large number of eye plates 1 a protruding around the floating body 1.

Next, a second embodiment will be described with reference to FIGS. The second embodiment is different from the first embodiment in that a spring 10 with a pedestal capable of supporting the weight 5 is provided on the upper surface of the pedestal 6, and the spring 4 is eliminated and the base end of the wire 2 is provided. Weight 5 is bound. A weight spring 14 is attached to the upper surface of the weight 5, and a stopper plate is provided on the upper part of the weight spring 14 to abut against the stopper 8 from below to prevent the weight spring 14 from passing through the opening 8 a of the stopper 8.
14a is provided. Other points are the same as those of the first embodiment.

In the above configuration, when the floating body 1 is at rest, the weight 5 rides on the pedestal spring 10 and the weight 5 is compressing the pedestal spring 10. In the first region where the wave height is low, when the floating body 1 swings in the vertical direction and the load on the wire 2 fluctuates, the weight 5 moves up and down on the pedestal spring 10.
Thereby, the pedestal spring 10 expands and contracts, and the swaying of the floating body 1 is suppressed by the expansion and contraction of the pedestal spring 10. Therefore, in the first region, the reaction force characteristic of the floating body mooring device is “(first) proportional reaction force characteristic”.

The position of point P in the reaction force characteristic graph of FIG. 5, that is, the proportionality constant, can be arbitrarily set by selecting a pedestal spring 10 constant. The operation at the time of high wave height (second region) is the same as that of the first embodiment. In the third region where the wave becomes higher, the weighted spring 14 is compressed by the stopper 8, and the reaction force characteristic of the device becomes "(second) proportional reaction force characteristic".

In the second embodiment, in addition to the advantages of the first embodiment, the spring constants of the pedestal spring 10 and the weight spring 14 can be individually selected.
