本発明は船体傾斜防止装置に係り、特に船上クレーンを
用いた荷役作業中に於ける船体の傾斜を防止する装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing the hull from tilting, and more particularly to a device for preventing the hull from tilting during cargo handling operations using a shipboard crane.
近年、効率的物流指向から出来るだけ小さい船舶に可能
な限りの貨物を積み込む傾向にあり、そのため貨物１ユ
ニツトの重量化も合いまって船上クレーンに於ける荷役
作業中の船体安定度の不足が問題となってきた。In recent years, there has been a trend to load as much cargo as possible onto as small a ship as possible in order to achieve efficient logistics, and as a result, the weight of each unit of cargo has increased, resulting in a lack of stability of the ship's body during cargo handling operations using onboard cranes. It has become.
従来のこの対策として、船上クレーンを２台装備する船
にあっては、これらを電気的にインターロックして互い
に反対方向へ横行トロリを作動させ、１台のクレーンを
カウンターウェイト化りに使用する方法がある。As a conventional countermeasure for this, on ships equipped with two onboard cranes, these are electrically interlocked to operate the traversing trolleys in opposite directions, and one crane is used as a counterweight. There is a way.
しかし、これでは荷役効率が悪くなるばかりでなく、価
格も高くなりまた比較的大型船舶に限られる欠点がある
。However, this method not only reduces cargo handling efficiency but also increases costs and has the disadvantage that it is limited to relatively large ships.
本発明の目的は上記従来の問題点を解消し、あらゆる船
舶に適用できると共に、構造も簡便でかつ確実な船体傾
斜防止を行なうことができる船体傾斜防止装置を提供す
るにある。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems, and to provide a hull heel prevention device that can be applied to all types of ships, has a simple structure, and can reliably prevent the hull from tilting.
この目的を達成するために、本発明の装置は、船上から
の操作で水を導入・排出することができるタンクと、船
体の側舷部に設けられ前記タンクを少なくとも水面レベ
ルまで吊り下げることができるタンク懸吊装置とを備え
るようにしたものである。To achieve this objective, the device of the present invention includes a tank that can introduce and discharge water by operation from the ship, and a tank that is installed on the side of the ship and that allows the tank to be suspended at least to the water level. It is equipped with a tank suspension device that can be used.
以下図面に示す実施例を参照しながら本発明の詳細な説
明する。The present invention will be described in detail below with reference to embodiments shown in the drawings.

２０は積み込まれた貨物である。FIG. 1 is a sectional view of a ship body equipped with a ship tilt prevention device according to an embodiment, in which 10 is a quay, 12 is a sea surface, 14 is a hull, 16 is a shipboard crane body, and 18 is a crane body 16.
Traversing Toro IJ, which crosses over and loads and unloads cargo.
20 is the loaded cargo.
しかして船上クレーン本体１６の先端部（カンチレバー
）には懸吊装置２２のロープ２４を介してタンク２６が
吊り下げられている。A tank 26 is suspended from the tip (cantilever) of the shipboard crane body 16 via a rope 24 of a suspension device 22.
この懸吊装置２２は、前記ロープ２４および該ロープ２
４巻取用の巻取装置２８及びタンク運搬用ロープ５０及
び該ロープ５０巻取用の巻取装置５１とから構成されて
いる。This suspension device 22 includes the rope 24 and the rope 2
It is composed of a winding device 28 for winding up four windings, a rope 50 for transporting a tank, and a winding device 51 for winding up the rope 50.
第２図はタンク２６の構造を示す断面図である。FIG. 2 is a sectional view showing the structure of the tank 26.

ド４０と、前記弁体３６を海水導入口開放方向へ付勢す
るスプリング４２と、空気タンク４４と、を備えて構成
されたものである。This tank 26 includes a tank main body 34 having a rope connecting eye 30 on the top surface and a seawater inlet 32 on the bottom surface, and a valve body 3 that moves toward and away from the seawater inlet 32 to block the seawater inlet 32 from the outside.
6, a valve rod 40 having one end fixed to the surface of the valve body 36 on the side of the tank body 34 and a rope connecting eye 38 provided at the other end, and a valve rod 40 that urges the valve body 36 in the direction of opening the seawater inlet This configuration includes a spring 42 and an air tank 44.
このように構成された装置を使用するには、荷役開始前
に、ロープ２４をアイ３８に又ロープ５０をアイ３０に
連結した後タンク２６を岸壁１０と反対側の海面１２に
落とす。To use the apparatus configured in this manner, before the start of cargo handling, the rope 24 is connected to the eye 38 and the rope 50 is connected to the eye 30, and then the tank 26 is dropped onto the sea surface 12 on the opposite side from the quay 10.
弁体３６はスプリング４２で付勢されているところから
海水導入口３２開放方向に移動し、海水導入口３２から
海水が流入しタンク本体３４内が海水で満たされるが、
空気タンク４４の浮力によって、タンク２６は海面１２
上に浮んでいる。The valve body 36 moves in the direction of opening the seawater inlet 32 from where it is biased by the spring 42, and seawater flows in from the seawater inlet 32, filling the tank body 34 with seawater.
Due to the buoyancy of the air tank 44, the tank 26 remains at sea level 12.
floating above.
第１図はこの状態に係るものであって、トロリ１８はク
レーン本体１６の中央にあり、船体１４は水平状態とな
っている。FIG. 1 shows this state, in which the trolley 18 is located at the center of the crane body 16 and the hull 14 is in a horizontal state.
またロープ５０は充分たるんでおりロープ２４には若干
の余裕がある。Further, the rope 50 is sufficiently slack, and the rope 24 has some slack.
ロープ５０の余裕はロープ２４の余裕よりも上回ってい
る。The margin of the rope 50 exceeds the margin of the rope 24.
トロリ１８が、第３図に示されるように貨物２０のうち
の１個２１を吊って舷外に出て行くと、船体は傾斜する
。When the trolley 18 hangs one piece 21 of the cargo 20 and goes out overboard as shown in FIG. 3, the hull of the ship is tilted.
これによりタンク２６はロープ２４により海面１２から
上方に持ち上げられ、このタンク２６の自重により、ト
ロリ１８および貨物２１の加えるモーメントと逆方向の
モーメントが船体１４に作用し船体１４の傾斜が抑制さ
れる。As a result, the tank 26 is lifted upward from the sea surface 12 by the rope 24, and due to the weight of the tank 26, a moment in the opposite direction to the moment applied by the trolley 18 and the cargo 21 acts on the hull 14, suppressing the tilting of the hull 14. .
タンク２６が持ち上げられた状態にあっては、弁ロッド
４０従って弁体３６も上方に引張られ、弁体３６が海水
導入口３２を塞ぐ。When the tank 26 is in the lifted state, the valve rod 40 and therefore the valve element 36 are also pulled upward, and the valve element 36 closes the seawater inlet 32.
そのためタンク２６から海水の流出はない。Therefore, seawater does not flow out from the tank 26.
トロリ１８を巻取装置２８側に移動させたときには、船
体１４は第２図と逆方向に傾斜するが、タンク２６は海
水に浮かぶところからタンク２６の自重は船体１４には
作用しない。When the trolley 18 is moved to the take-up device 28 side, the hull 14 tilts in the opposite direction to that shown in FIG. 2, but the weight of the tank 26 does not act on the hull 14 because the tank 26 floats on seawater.
荷役終了後にはロープ５０を該ロープ巻取装置５１によ
り巻取り、タンク２６を吊り下げると、タンク内の海水
の自重およびスプリング４２の付勢力によって海水導入
口３２が開き、タンク内の海水が流出する。After cargo handling is completed, the rope 50 is wound up by the rope winding device 51 and the tank 26 is suspended, and the seawater inlet 32 opens due to the weight of the seawater in the tank and the biasing force of the spring 42, and the seawater in the tank flows out. do.
なお、懸吊装置２２に移動手段を設け、荷役終了後には
タンク２６を巻き上げると共に船体１６内に移動させ、
船体１６内にタンク１２を格納するようにしても良い。In addition, a moving means is provided in the suspension device 22, and after cargo handling is completed, the tank 26 is hoisted up and moved into the hull 16,
The tank 12 may be stored within the hull 16.
上記実施例に於いては、タンク懸吊装置２２はクレーン
本体１６の先端部に設けられているが、本発明に於いて
は、船体の側舷に張り出すように腕部を設け、この腕部
に懸吊装置を設けるようにしても良い。In the above embodiment, the tank suspension device 22 is provided at the tip of the crane body 16, but in the present invention, an arm is provided so as to protrude from the side of the hull, and this arm A suspension device may be provided in the section.
