ものである。DETAILED DESCRIPTION OF THE INVENTION [Target Technology] The present invention relates to a shipboard gantry crane, and particularly relates to a shipboard gantry crane with foldable legs.
［従来の技術］
第１．２図は、従来の代表的な船上ガントリクレーンの
概略図である。[Prior Art] Fig. 1.2 is a schematic diagram of a typical conventional shipboard gantry crane.

輪９を備えたトラックマあり、Ｈはガントリクレーン高
さである。In Figure 1.2, 1 is the hull, 2 is a rail provided on the deck of the hull 1 in the longitudinal direction of the hull, 3 is the leg of a gantry crane 4, 5 is a girder with an openable cantilever, and 6 is a trolley. , 7 is a hook, 8 is a track machine with wheels 9 running on rails 2, and H is the height of the gantry crane.
従来の船上ガントリクレーン４では、脚３が垂直に押び
た一本ものであり、高さが比較的に高く、したがって、
重心が高かった。In the conventional shipboard gantry crane 4, the leg 3 is a single vertically pushed leg, and the height is relatively high.
My center of gravity was high.
このため、航海中の船においては、ローリング、ピッチ
ングが起こりやすく、船の安定性が著しく悪かった。For this reason, rolling and pitching are likely to occur in ships during voyage, resulting in extremely poor ship stability.
しかもそのため、ガーダ５や脚３の強度計算条件が厳し
くなっていた。また、その他にガントリクレーン４の船
体１への係留、ツなわら、固定が難しいなどの欠点が生
じていた。Moreover, for this reason, the strength calculation conditions for the girder 5 and the legs 3 have become stricter. In addition, there have been other drawbacks such as difficulty in mooring, tying, and fixing the gantry crane 4 to the hull 1.
［発明の目的］
本発明は、以上のような欠点を解消したもので、脚部を
折曲げ式にし、ガントリクレーンの不使用時には、その
高さを低くして、船全体の重心が低くなるようにし、船
の安定性が良くなるようにしたものである。[Object of the invention] The present invention solves the above-mentioned drawbacks, and the legs are made foldable, so that when the gantry crane is not in use, its height is lowered, thereby lowering the center of gravity of the entire ship. This was done to improve the stability of the ship.
［構造の説明］
以下、図面に示す１実施例によって、発明の詳細な説明

た。FIG. 3.4 shows the leg 10 in a bent state, and FIG.
The leg 10 is not shown in a vertically extended state. ' In Figures 3 to 5, legs 10 having pin hinges 11 and 12 at both ends are provided between the lower part of the girder 5 and the upper sides of racks 1 to 8. A clevis-shaped cylinder 13 is installed between the legs 10 on both sides, and by the action of the cylinder 13 both legs 10 and the track 8 can be opened on the rail 2 as shown in FIG. 4 or as shown in FIG. It was made so that it could be stood vertically. Also, a hole 14 is provided in a part of both legs 10, and when the legs 10 are stood vertically, as shown in FIG. A connecting member 16 was placed between the legs 10 of the legs 10 to prevent both legs 10 from opening. Of course, if hydraulic pressure is constantly applied to the cylinder 13 in the state shown in FIG.
However, this would be uneconomical and unsafe, so the connecting member 16 was used in this embodiment.
なお、ガントリクレーン４を走行させないで、第４図な

Of course, the truck 8 rides on the rail 2 via normal wheels 9, but this
It is also possible to use a shear-shaped rail and a binion-shaped wheel together to form part of the mooring device.
［作用の説明］
次に、以上の様に構成された本実施例の作用について説

そして、安全のために、連結部材１６を両脚１０間に取
付ける。Then, for safety, a connecting member 16 is attached between both legs 10.
航海時には、連結部材１６を取った後、シリンダ１３を

論、船のゆれによってガントリクレーン４が動かないよ
うに、ガントリクレーン４は船体１又はレール２に固定
させておく。During voyage, after the connecting member 16 is removed, the legs 10 are opened using the cylinder 13 to shift to the state shown in FIG. 4, thereby lowering the center of gravity of the gantry crane 4. Of course, the gantry crane 4 is fixed to the hull 1 or the rail 2 so that the gantry crane 4 does not move due to the shaking of the ship.
［発明の効果］
以上のように、本発明においては、航海特に脚を折曲げ
てガントリクレーンの重心を低くすることができるので
、船の安定性が良くなる。[Effects of the Invention] As described above, according to the present invention, the center of gravity of the gantry crane can be lowered by bending the legs, which improves the stability of the ship.
また、船の安定が良くなるので、荷重条件がよくなり、
ガーダ、脚の強度計算条件が従来に比べて有利になる。It also improves the stability of the ship, which improves load conditions.
The strength calculation conditions for girders and legs are now more advantageous than before.
さらに、クレーンの船体への係留も容易にできるなどの
効果が生じる。Furthermore, the crane can be easily moored to the ship's hull.
