。[Problem to be solved by the invention 9 According to the conventional single-point mooring device as shown above, the floating body has no means of detachment and cannot evacuate in the event of a storm, so the sea area where it can be installed is limited. Alternatively, it has the disadvantage that it requires a design that can withstand excessive loads and movements.
また、浮体とヨークの連結部のピン構造は。Also, what is the pin structure of the connection between the floating body and the yoke?
繰返される摺動のため、摩耗への配慮が重要であり、許
容量以上の摩耗が生じた時の補修あるいは部品交換は多
大な工事量を要するものになるという欠点がある。Due to repeated sliding, it is important to take wear and tear into account, and when wear exceeds the allowable amount, repair or parts replacement requires a large amount of work.
本発明は、以上のような従来技術の欠点を解決するもの

可能な連結機構を具備したことを特徴としている。Therefore, the single-point mooring device of the present invention includes a buoy body anchored to the seabed via a mooring line, a rotary table installed on the top of the buoy body so as to be rotatable in a horizontal plane, and one end attached to the rotary table. In a one-point mooring device consisting of a yoke, etc., which is fixed and whose other end is connected to a floating body to be moored, a fitting member having a cylindrical surface in the horizontal direction is attached to the floating body side end of the yoke, and the fitting member has a downward opening in the floating body side wall. The present invention is characterized in that it includes a removable connection mechanism that is fitted into the member to be fitted and is a hanging device that suspends the floating body side end of the yoke from above the member to be fitted so that it can rise and fall freely.
上記構成により、ヨーク端部の嵌合部材は。 With the above configuration, the fitting member at the end of the yoke.
