Description

本発明は、連結された部材を切り離す切離機構に関する。   The present invention relates to a separation mechanism that separates connected members.

従来、連結された部材を切り離す切離機構としては、分離可能な２個の部材に２本のローラを軸支し、前記２本のローラを結束するように該２本のローラ間に電食線を全体として該ローラの軸線方向に位置をずらせて複数回巻き付け、前記ローラ相互間に加わる荷重を分散させるようにし、電食線を切断後スムーズに離脱させるものがある。（特許文献１参照）
また、他の従来技術を図１０乃至１３に示す。図中１は第１部材を構成する浮力体、１ａはロッド取付部、２はブラケットを構成するロッド、３は切離装置、３ａは切離装置の一方部、３ｂは切離装置の他方部、１１は第２部材を構成するアンカー、１２は保持部、Ｄは切離機構を示す。 Conventionally, as a separation mechanism for separating the connected members, two rollers are pivotally supported on two separable members, and the electric corrosion is caused between the two rollers so as to bind the two rollers. There is one in which the wire as a whole is shifted in the axial direction of the roller and wound several times to disperse the load applied between the rollers, and the galvanic wire is smoothly separated after cutting. (See Patent Document 1)
Other conventional techniques are shown in FIGS. In the figure, 1 is a buoyant body constituting the first member, 1a is a rod mounting portion, 2 is a rod constituting a bracket, 3 is a separating device, 3a is one part of the separating device, and 3b is the other part of the separating device. , 11 is an anchor constituting the second member, 12 is a holding portion, and D is a separation mechanism.

図１０は従来の切離装置を有する浮力体を海底に設置した図である。浮力体１は内部に海底設置型の地震計や各種調査等の観測装置を収納している略球形の構造を有し、外周にロッド取付部１ａを備えている。切離機構Ｄは、ロッド取付部１ａの図１０における左右両側に結合されたロッド２と、ロッド２とアンカー１１とを浮力体１の設置時は連結し、浮力体１の回収時は切り離しする切離装置３と、アンカー１１から垂直方向に延びた保持部１２とで構成されている。ロッド２は一端が浮力体１のロッド取付部１ａに結合され、他端は切離装置３の一方部３ａと結合された鉛直棒状の部材である。切離装置３は、ロッド２とともに、浮力体１とアンカー１１とを連結しており、普段は一体である二つの部分を、音響等のコマンド信号やタイマ等により作動する電蝕式、ガス圧式又は爆発ボルト式等の分離手法を利用して２つの部分に分離させる装置である。切離装置３の２つの部分のうち一方部３ａはロッド２に、他方部３ｂはアンカー１１から垂直に延びる保持部１２に結合されている。アンカー１１は海底に沈められた錘であり、アンカー１１から垂直方向に延びる保持部１２を介して切離装置３の他方部３ｂに結合されている。この構造により、浮力体１は浮遊せずに、海底に設置されたアンカー１１に保持される。   FIG. 10 is a diagram in which a buoyant body having a conventional separating device is installed on the seabed. The buoyancy body 1 has a substantially spherical structure in which an observation device such as a submarine seismometer and various surveys is housed, and has a rod mounting portion 1a on the outer periphery. The separation mechanism D connects the rod 2 coupled to the left and right sides of the rod mounting portion 1a in FIG. 10 with the rod 2 and the anchor 11 when the buoyancy body 1 is installed, and disconnects when the buoyancy body 1 is recovered. The separating device 3 and a holding portion 12 extending from the anchor 11 in the vertical direction are configured. One end of the rod 2 is coupled to the rod mounting portion 1 a of the buoyancy body 1, and the other end is a vertical bar-shaped member coupled to one portion 3 a of the separating device 3. The detaching device 3 connects the buoyant body 1 and the anchor 11 together with the rod 2, and the two parts that are usually integrated are electrically eroded and gas pressure operated by a command signal such as sound or a timer. Or it is an apparatus which makes it isolate | separate into two parts using separation techniques, such as an explosion bolt type. Of the two parts of the cutting device 3, one part 3 a is connected to the rod 2, and the other part 3 b is connected to a holding part 12 extending perpendicularly from the anchor 11. The anchor 11 is a weight submerged in the seabed, and is coupled to the other portion 3b of the separation device 3 via a holding portion 12 extending from the anchor 11 in the vertical direction. With this structure, the buoyancy body 1 is not floated but is held by the anchor 11 installed on the seabed.

図１１は切離装置３が作動する前の切離機構Ｄを拡大した図である。作動前、切離装置３は二つの部分が連結された状態なので、浮力体１とアンカー１１とは、切離機構Ｄを介して連結されている。図１２は切離装置３が作動した後の切離機構Ｄを拡大した図である。切離装置３は海上等の遠隔からのコマンド信号等により一方部３ａと他方部３ｂの二つの部分を分離させ、連結状態を切り離す。図１３は切離装置３が作動した後の全体図である。切離装置３が切り離されると、浮力体１は浮力により浮上する。そして、浮力体１はアンカー１１から完全に切り離され、浮上することになる。
特開昭６０−６６１１５号公報 FIG. 11 is an enlarged view of the separation mechanism D before the separation device 3 operates. Before the operation, since the separation device 3 is in a state where two parts are connected, the buoyancy body 1 and the anchor 11 are connected via the separation mechanism D. FIG. 12 is an enlarged view of the separation mechanism D after the separation device 3 is operated. The disconnecting device 3 separates the two parts of the one part 3a and the other part 3b by a command signal or the like from a remote place such as at sea, and disconnects the connected state.

上記従来技術では、切離装置３を作動させると、切離装置３は一方部３ａをロッド２に、他方部３ｂをアンカー１１に残した状態で分離される構造となっており、特に海底に残った切離装置３の他方部３ｂは再利用することが困難となる。 また、直接切離装置３が浮力体１とアンカー１１との間の張力を受けているため、切離装置３に作用する張力の負荷荷重を加減操作することができない。さらに、切離機構Ｄを二つ用いた場合に、双方が正常に切り離されないと浮力体１がアンカー１１から切り離されないという問題点を有している。   In the above prior art, when the separating device 3 is operated, the separating device 3 is separated with the one portion 3a remaining on the rod 2 and the other portion 3b remaining on the anchor 11, and particularly on the seabed. It is difficult to reuse the remaining part 3b of the separation device 3 that remains. Further, since the direct separating device 3 receives the tension between the buoyant body 1 and the anchor 11, the load load of the tension acting on the separating device 3 cannot be adjusted. Further, when two separation mechanisms D are used, there is a problem that the buoyancy body 1 is not separated from the anchor 11 unless both are separated normally.

そのために本発明は、第１部材と第２部材との間の連結を切り離す切離機構において、前記第１部材に結合されたブラケットと、前記ブラケットに一方を結合されたヒンジと、一方部を前記ヒンジの他方に結合され、他方部を第２部材に保持されたアームと、通常前記ブラケットと前記アームとを前記ヒンジが閉状態で連結し、切り離し時に前記ブラケットと前記アームとの連結を切り離す切離装置と、前記第２部材に設け、前記アームを保持する保持部とを備え、前記第１部材の前記切離装置による前記ブラケットと前記アームとの連結の切り離しによって、前記ブラケットと前記アームとを前記ヒンジを中心に開くことで、前記アームを前記第２部材の前記保持部による保持から切り離し、前記第１部材と前記第２部材との連結を切り離すことを特徴とする。   Therefore, the present invention provides a separation mechanism for disconnecting the connection between the first member and the second member, a bracket coupled to the first member, a hinge coupled to the bracket, and one portion. The arm coupled to the other of the hinges and having the other part held by the second member is connected to the bracket and the arm in a closed state, and the connection between the bracket and the arm is disconnected when the hinge is disconnected.

また、前記切離機構は、前記第２部材に前記アームを保持する保持部を有し、前記保持部の先端はピンにより回動可能に枢支されたことを特徴とする。   Further, the separation mechanism has a holding portion for holding the arm on the second member, and a tip end of the holding portion is pivotally supported by a pin.

また、前記切離機構は、二つ設けられ、どちらか一方のみが作動すれば、他方が作動しなくても、前記第１部材と前記第２部材との保持を切り離すことが可能であることを特徴とする。   Further, two separation mechanisms are provided, and if only one of them operates, the holding of the first member and the second member can be separated even if the other does not operate. It is characterized by.

第１部材と第２部材との間の連結を切り離す切離機構において、前記第１部材に結合されたブラケットと、前記ブラケットに一方を結合されたヒンジと、一方を前記ヒンジの他方に結合され、他端部を第２部材に保持されたアームと、通常前記ブラケットと前記アームとを前記ヒンジが閉状態で連結し、切り離し時に前記ブラケットと前記アームとの連結を切り離す切離装置と、前記第２部材に設け、前記アームを保持する保持部材とを備え、前記第１部材の前記切離装置による前記ブラケットと前記アームとの連結の切り離しによって、前記ブラケットと前記アームとを前記ヒンジを中心に開くことで、前記アームを前記第２部材の前記保持部による保持から切り離し、前記第１部材と前記第２部材との連結を切り離すので、切り離された後の分離した切離装置がどちらも第１部材に存在し、切離装置を再利用することが容易となり、低コスト化ができる。   In the separation mechanism for disconnecting the connection between the first member and the second member, a bracket coupled to the first member, a hinge coupled to the bracket, and one coupled to the other of the hinges.

また、前記切離機構は、前記第２部材に前記アームを保持する保持部を有し、前記保持部の先端はピンにより回動可能に枢支されているので、第１部材の切り離しの時にアームが保持部から抜けやすくなる。   In addition, the separation mechanism has a holding portion for holding the arm on the second member, and the tip of the holding portion is pivotally supported by a pin so that the first member can be separated. The arm can be easily removed from the holding part.

また、前記切離機構は、二つ設けられ、どちらか一方のみが作動すれば、他方が作動しなくても、前記第１部材と前記第２部材との保持を切り離すことが可能なので、切離機構の双方が正常に切り離されなくても、どちらか一方のみが正常に作動しさえすれば、第１部材が第２部材から切り離される。   In addition, two separation mechanisms are provided, and if only one of them operates, the holding of the first member and the second member can be separated even if the other does not operate.

図５は切離装置３が作動した後の全体概略図である。なお、理解を容易にするために環状部は向きを変えて記載してある。切離機構Ｄは浮力体１のロッド保持部材１ａの円周上に中心に対して１８０度離れて二つ備えられており、通常、切離装置３の作動は、一つのコマンド信号等で二つ同時に行われる。図４で説明したように切り離しが行われ、アーム５がアーム保持部１２の環状部１３から抜けると、浮力体１は浮力により浮上していく。   FIG. 5 is an overall schematic view after the cutting device 3 is operated. In addition, in order to make an understanding easy, the cyclic | annular part is changing and describing. Two separation mechanisms D are provided on the circumference of the rod holding member 1a of the buoyancy body 1 180 degrees away from the center. Normally, the operation of the separation device 3 is performed by one command signal or the like. One at a time. As described with reference to FIG. 4, when the arm 5 is detached from the annular portion 13 of the arm holding portion 12, the buoyancy body 1 is lifted by buoyancy.

図６はアームの変形例を示すものである。図６において、６は延長アーム、６ａは第１延長アーム、６ｂは第２延長アームである。図６に示した実施形態では、切離装置３が延長アーム６を介してロッド２及びアーム５と結合する構造である。第１延長アーム６ａは一端をロッド２と結合し、ロッド２からヒンジ４と逆方向に伸び、他端で切離装置３の一方部３ａと結合する。第２延長アーム６ｂは一端をアーム５と結合し、アーム５の一方部５ａからヒンジ４と逆方向に伸び、他端で切離装置３の他方部３ｂと結合する。延長アーム６の長さを調節し、切離装置３とヒンジ４からの距離を調節することによって、切離装置３に作用する張力ｂは次の式で変化する。
ｂ＝（Ｘ×ａ）／Ｙ
ここで、ａはアーム５に作用する荷重、Ｘはヒンジ４からアーム５の荷重ａが作用する点までの距離、Ｙはヒンジ４から切離装置３の作用張力が作用する点までの距離である。すなわち、延長アーム６の距離を調節することによって、張力の負荷荷重を加減操作することができる。 FIG. 6 shows a modification of the arm. In FIG. 6, 6 is an extension arm, 6a is a first extension arm, and 6b is a second extension arm.

One end of the second extension arm 6 b is coupled to the arm 5, extends from one part 5 a of the arm 5 in the opposite direction to the hinge 4, and is coupled to the other part 3 b of the separation device 3 at the other end. By adjusting the length of the extension arm 6 and adjusting the distance from the separating device 3 and the hinge 4, the tension b acting on the separating device 3 is changed by the following equation.
b = (X × a) / Y
Here, a is the load acting on the arm 5, X is the distance from the hinge 4 to the point where the load a of the arm 5 acts, and Y is the distance from the hinge 4 to the point where the acting tension of the separating device 3 acts. is there. That is, by adjusting the distance of the extension arm 6, the load load of the tension can be adjusted.

In FIG. 7, reference numeral 14 denotes a pin. In this modification, the arm holding part 12 and the annular part 13 are formed as separate members, and the arm holding part 12 and the annular part 13 are connected to each other via a pin 14 so as to be tiltable. With such a configuration, the separation device 3 operates, the buoyant body 1 is lifted by buoyancy, and the hinge 4 is gradually opened, so that when the one arm 5 is inclined, the annular portion 13 is moved. Is pushed by the arm 5 and tilts, so that the arm 5 can exit the annular portion 13 more smoothly.

図８は片方の切離装置３のみ作動した後の全体概略図である。なお、理解を容易にするために環状部は向きを変えて記載してある。図５に示したように、切離機構Ｄは浮力体１のロッド保持部材１ａの円周上に中心に対して１８０度離れて二つ備えられており、通常、切離装置３の作動は、一つのコマンド信号等で二つ同時に行われる。しかしながら、故障等の何らかの要因で片方の切離装置３しか作動しない場合がある。   FIG. 8 is an overall schematic view after only one of the separating devices 3 is operated. In addition, in order to make an understanding easy, the cyclic | annular part is changing and describing. As shown in FIG. 5, two separation mechanisms D are provided on the circumference of the rod holding member 1 a of the buoyancy body 1, 180 degrees apart from the center, and the operation of the separation device 3 is usually performed. Two are performed simultaneously by one command signal or the like. However, there are cases where only one of the separation devices 3 is activated due to some cause such as a failure.

このような場合、アーム５の他方部５ｂの水平部分の長さを調整する。一方の切離装置３が作動し切り離されると、浮力体１は浮力によりに浮上し、ヒンジ４が徐々に開くことで、一方のアーム５が傾斜していき環状部１３から抜ける。すると、浮力体１は浮上に伴って傾斜していき、その結果、他方のアーム５は、徐々に傾斜していき、他方の切離装置３が作動しなくても、アーム保持部１２の環状部１３から抜けることができる。そして、浮力体１はアンカー１１から完全に切り離され、浮上することになる。なお、このような作動は、図６又は図７で示した実施形態においても適用可能である。   In such a case, the length of the horizontal portion of the other portion 5b of the arm 5 is adjusted. When one of the separating devices 3 is operated and disconnected, the buoyancy body 1 is lifted by buoyancy, and the hinge 4 is gradually opened, so that one arm 5 is inclined and comes out of the annular portion 13. Then, the buoyancy body 1 is inclined as it rises, and as a result, the other arm 5 is gradually inclined, and even if the other separating device 3 does not operate, The part 13 can be removed. Then, the buoyancy body 1 is completely separated from the anchor 11 and floats. Such an operation can also be applied to the embodiment shown in FIG. 6 or FIG.

図９は他の実施形態を示すものである。図９において、２１は船、２２はクレーン、２３はクレーンアーム、２４はドラム、２５は第１部材を構成するワイヤ、３１は第２部材を構成する潜水艦、３２は環状部を示す。船２１は船尾に回転可能なクレーン２２を有し、クレーン２２はクレーンアーム２３、ドラム２４及びワイヤ２５を備える。クレーン２２はクレーンアーム２３に掛けられ、ドラム２４に巻かれたワイヤ２５を操作することで潜水艦３１を昇降可能に支持することができる。ワイヤ２５の一端はドラムに結合され、他端は切離機構Ｄのロッド２の一端部２ａに結合され、ロッド２の他端部２ｂは並列に並んだ切離装置３の一方部３ａ及びヒンジ４の一方部４ａに結合され、さらに切離装置３の他方部３ｂ及びヒンジ４の他方部４ｂはアーム５に結合されている。アーム５は一方部５ａがヒンジ４の他方部４ｂに結合し、他方部５ｂの水平部分が潜水艦３１の環状部３２を支持する。   FIG. 9 shows another embodiment. In FIG. 9, 21 is a ship, 22 is a crane, 23 is a crane arm, 24 is a drum, 25 is a wire constituting a first member, 31 is a submarine constituting a second member, and 32 is an annular portion. The ship 21 has a crane 22 that can rotate at the stern, and the crane 22 includes a crane arm 23, a drum 24, and a wire 25. The crane 22 is hung on the crane arm 23, and can operate the wire 25 wound around the drum 24 to support the submarine 31 so that it can be moved up and down. One end of the wire 25 is coupled to the drum, the other end is coupled to one end 2a of the rod 2 of the separation mechanism D, and the other end 2b of the rod 2 is connected to the one portion 3a and the hinge of the separation device 3 arranged in parallel. 4, and the other part 3 b of the separation device 3 and the other part 4 b of the hinge 4 are connected to the arm 5. One part 5 a of the arm 5 is coupled to the other part 4 b of the hinge 4, and the horizontal part of the other part 5 b supports the annular part 32 of the submarine 31.

本実施形態では第２部材としての潜水艦３１を海上に切り離すための切離機構Ｄを示す。船２１に搭載された潜水艦３１は、環状部３２が設けられ、環状部３２の穴に切離機構Ｄのアーム５を通過させることで吊り下げ可能に支持される。切離機構Ｄに支持され、クレーン２２により吊り下げられた潜水艦２６は、クレーン２２を操作することで海上に浮かべられる。潜水艦３１が海上に浮かんだ状態で、切離装置３は海上からの信号等により保持状態を解放する。すると、潜水艦３１が落下するのに伴って、ヒンジ４が徐々に開き、傾斜したアーム５が潜水艦３１の環状部２７から抜けることができる。なお、本実施形態でも切離機構Ｄを二つ設けることは可能である。   In the present embodiment, a separation mechanism D for separating the submarine 31 as the second member to the sea is shown. The submarine 31 mounted on the ship 21 is provided with an annular portion 32, and is supported so as to be suspended by passing the arm 5 of the separation mechanism D through the hole of the annular portion 32. The submarine 26 supported by the separation mechanism D and suspended by the crane 22 is floated on the sea by operating the crane 22. With the submarine 31 floating on the sea, the separation device 3 releases the holding state by a signal from the sea. Then, as the submarine 31 falls, the hinge 4 is gradually opened, and the inclined arm 5 can be removed from the annular portion 27 of the submarine 31. In this embodiment, it is possible to provide two separation mechanisms D.

また、さらに他の実施形態として、気球のような浮遊物を設置部から切り離す切離機構としても使用することができる。   As still another embodiment, the present invention can also be used as a separation mechanism that separates floating substances such as balloons from the installation part.
