【発明の詳細な説明】 本発明は係船装置に関する。[Detailed description of the invention] The present invention relates to a mooring device.
岸壁に船舶を係留するには、第１図平面図に示
すように、水面２上の船舶１を複数本の係留索４
で岸壁３に引き寄せ、岸壁３には適宜間隔で複数
個のフエンダー５が突設されており船舶１と岸壁
３の間の緩衝材となつている。 To moor a ship to a quay, as shown in the plan view of Figure 1, the ship 1 on the water surface 2 is moored with multiple mooring lines 4.
A plurality of fenders 5 are protruded from the quay 3 at appropriate intervals and serve as a buffer between the ship 1 and the quay 3.
しかしながら、このような従来の係留方法は、
風や波が小さいうちは、船舶１を岸壁３に引き寄
せて係留しておくことが可能であるが、風や波が
大きい荒天時には、船舶１が岸壁３から離れるよ
うに作用する外力が大きくなるので、安全に船舶
することができなくなり、係留索４が破断するな
どの事故が発生するようになる。 However, such conventional mooring methods
While the wind and waves are small, it is possible to pull the ship 1 to the quay 3 and keep it moored there, but in stormy weather with large winds and waves, the external force that acts to move the ship 1 away from the quay 3 increases. Therefore, it becomes impossible to sail safely, and accidents such as breakage of mooring ropes 4 occur.
これは、係留された船舶１は一般に波あるいは
風などから外力を受けて動揺し、係留索４には、
第２図線図に示すように張力６が作用し、この張
力６は主として風圧力に基づく定常力７を平均力
とし、これに波や風による変動外力に基づく変動
成分が重なつた波形を示し、係留索４に張力６が
作用することによつて係留索４が伸びることとな
るが、平均的に定常力７が作用した分だけ船舶１
は岸壁３から離れることによる。 This is because the moored ship 1 generally sways due to external forces such as waves or wind, and the mooring lines 4
As shown in the second diagram, tension 6 acts, and this tension 6 has a waveform in which the average force is a steady force 7 mainly based on wind pressure, and fluctuating components based on fluctuating external forces due to waves and wind are superimposed on this. As shown, the mooring line 4 will be stretched by the tension force 6 acting on the mooring line 4, but on average the ship 1 will be stretched by the amount of the steady force 7 acting on it.
is due to moving away from quay 3.
船舶１が岸壁３から離れすぎることは安全上や
荷役作業の面から好ましくないので、船舶１を岸
壁３に引き寄せておくためには、係留索４のばね
定数を大きくすることが必要である。 Since it is undesirable for the ship 1 to be too far away from the quay 3 from the viewpoint of safety and cargo handling, it is necessary to increase the spring constant of the mooring line 4 in order to keep the ship 1 close to the quay 3.
しかし、ばね定数の大きい係留索４を使用して
も、船舶１の波による動揺を抑制することはでき
ないばかりか、かえつて係留索の張力６が異常に
大きくなり、容易に係留索４の破断荷重や船舶１
に装備されるウインチの容量を越えていまい、大
事故を引き起こす惧れが生ずる。 However, even if a mooring line 4 with a large spring constant is used, not only is it not possible to suppress the movement of the ship 1 due to waves, but the tension 6 of the mooring line becomes abnormally large, and the mooring line 4 easily breaks. Loads and vessels 1
If the capacity of the winch installed in the machine is exceeded, there is a risk of causing a serious accident.
このようなことから、従来の方法では高々１ｍ
程度の低い波高でま荷役作業を中断せざるを得な
い場合もあり、特に外洋からのうねりが進入し易
い港においては、港湾施設の年間の稼動日数が著
しく制限されるという不具合が生ずる。 For this reason, the conventional method has a distance of 1 m at most.
In some cases, cargo handling operations may have to be suspended due to low wave heights, and especially in ports where swells from the open ocean are likely to enter, the number of operating days of port facilities per year is severely limited.
本発明はこのような事情に鑑みて提案されたも
ので、荒天でも安全に船舶を係留する係船装置を
提供することを目的とする。 The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a mooring device for mooring a ship safely even in rough weather.

する。 To this end, the present invention provides a first arm member that is provided at an appropriate distance in the longitudinal direction of the quay, whose base end is pivotally connected to the quay, and extends substantially parallel to the water surface, and a distal end of the first arm member. a pair of front and rear foldable vertical arm members each consisting of a second arm member whose one end is pivotally connected and extends substantially parallel to the water surface;
A floating body which is pivotally attached to the tips of the arm members and floats on the water surface, a propulsion device attached to each of the floating bodies, a fender protruding from each of the floating bodies, and each pivot joint of each of the vertical arm members, respectively. A plurality of attached driving means are provided to vary the angle between adjacent members, and the vessel is moored along the quay by abutting each of the floating bodies on the opposite side of the quay at the bow and stern of the vessel, respectively. It is characterized by the following.
