Description

本発明は、陸上と船舶との間や浮島と船舶との間あるいは船舶間などで、例えば液化天然ガス（ＬＮＧ）や石油などの流体を、海上の波で船舶が揺動してもこれに追従しながら受け渡すことができる船舶受渡し用流体荷役装置に関するものである。 The present invention can be applied to a fluid such as liquefied natural gas (LNG) or oil between a land and a ship, between a floating island and a ship, or between ships, even if the ship fluctuates due to ocean waves. The present invention relates to a fluid handling apparatus for ship delivery that can be delivered while following.

例えば液化天然ガス（ＬＮＧ）や石油などの流体を、桟橋に接岸したタンカーから陸上の貯蔵タンクに荷上げしたり、逆に陸上の貯蔵タンクからタンカーに荷積みする場合、タンカーが波で揺動してもこれに追従しながら安全に荷役できる船舶受渡し用流体荷役装置が用いられている。 For example, when a fluid such as liquefied natural gas (LNG) or oil is unloaded from a tanker on the pier to an on-shore storage tank, or vice versa, the tanker swings in a wave. Even so, a fluid handling apparatus for ship delivery that can safely handle the truck while following it is used.

例えば桟橋などの陸上側とタンカーなどの船舶との間で流体を荷役する（受渡しする）場合、船舶が波で常時揺動するだけでなく、流体が高温であったり、低温であったり可燃であったりすることから耐温度性や防火性の要求などのため、単にゴム製のフレキシブルホースでの受渡しでは安全性や操作性に劣るから、揺動に追従でき耐温度性や防火性に優れたパイプを回動自在に組み合わせ連結した前記船舶受渡し用流体荷役装置が用いられている。 For example, when handling (delivering) fluid between a land such as a pier and a ship such as a tanker, not only does the ship constantly oscillate with waves, but the fluid is hot, cold, or flammable. Because there are demands for temperature resistance and fire resistance, etc., delivery with a rubber flexible hose is inferior in safety and operability, so it can follow oscillation and has excellent temperature resistance and fire resistance The above-mentioned fluid handling apparatus for ship delivery, in which pipes are combined and connected so as to freely rotate, is used.

この船舶受渡し用流体荷役装置は、例えば特公平３−４９８３９号公報などに示すようなローディングアームなどであって、一般に以下のように構成している。 This fluid delivery device for ship delivery is a loading arm as shown in, for example, Japanese Patent Publication No. 3-49839, and is generally configured as follows.

例えば桟橋や波止場や浮島などの受渡し部の一方側に設けた貯蔵タンクに連結させて船舶受渡し用流体荷役装置を設け、この船舶受渡し用流体荷役装置の先端部のジョイント部を、受渡し部の他方側となる船舶に設けた貯蔵タンクに連結するジョイント連結部（マニフォールド）に引き寄せ連結して、この間で流体を荷役するが、この船舶受渡し用流体荷役装置（ローディングアーム）は、一般に貯蔵タンクに連結している立ち上がり管（ライザパイプ）に設けられるもので、この立ち上がり管の上端部に水平中空回動継手（水平スイベルジョイント）及び垂直中空回動継手（垂直スイベルジョイント）を介して水平及び垂直方向に回動自在にインボードアームを設け、このインボードアームの先端部に垂直中空回動継手（垂直スイベルジョイント）を介して垂直方向に回動自在にアウトボードアームを設け、このアウトボードアームの先端部に緊急流体遮断離脱装置を介すると共に二つの垂直中空回動継手（垂直スイベルジョイント）と水平中空回動継手（水平スイベルジョイント）を介してジョイント部を設けた構成として、例えばインボードアームをライザパイプに対して垂直方向に倒伏回動並びに水平回動させつつこのインボードアームに対してアウトボードアームを開放回動させて先端部のジョイント部を、船舶に設けたジョイント連結部（マニフォールド）に接近させて連結し、流体を立ち上がり管からインボードアーム及びアウトボードアームを介し更にジョイント部とジョイント連結部との連結部分を介して船舶の貯蔵タンクに荷役できるように構成している。 For example, a fluid handling device for ship delivery is provided by being connected to a storage tank provided on one side of a delivery part such as a pier, wharf or floating island. It is drawn and connected to a joint connecting part (manifold) connected to a storage tank provided on the side ship, and the fluid is handled between them, but this ship delivery fluid handling device (loading arm) is generally connected to the storage tank It is provided in the riser pipe (riser pipe) that is connected to the upper end of the riser pipe through the horizontal hollow swivel joint (horizontal swivel joint) and the vertical hollow swivel joint (vertical swivel joint). An inboard arm is provided on the tip of the inboard arm, and a vertical hollow pivot joint (vertical swivel joint) is attached to the tip of the inboard arm. Via an emergency fluid shut-off device at the tip of the outboard arm and two vertical hollow pivot joints (vertical swivel joint) and a horizontal hollow loop. As a configuration in which a joint portion is provided via a dynamic coupling (horizontal swivel joint), for example, the inboard arm is tilted in the vertical direction with respect to the riser pipe, and the outboard arm is rotated with respect to the inboard arm while being rotated horizontally. The joint at the tip is moved close to the joint connecting part (manifold) provided on the ship, and the fluid is connected to the joint from the riser pipe via the inboard arm and outboard arm. It is comprised so that cargo handling can be carried out to the storage tank of a ship through the connection part with a part.

また、アウトボードアームの先端部に、垂直中空回動継手（トップスイベルジョイント），下端部を下方に向けるエルボ，水平中空回動継手（ミドルスイベルジョイント），緊急流体遮断離脱装置，先端部を水平方向に向けるエルボ，垂直中空回動継手を上方から順々に介して、連結面を水平横方向に向けた着脱連結機構（油圧カップラー）を備えたジョイント部を設けて、このジョイント部を異なる三方向に回動自在として、横方向からマニフィールドに接近させて連結する構成としている。 In addition, a vertical hollow rotary joint (top swivel joint), an elbow with the lower end facing downward, a horizontal hollow rotary joint (middle swivel joint), an emergency fluid shut-off and release device, and a tip horizontally The joint is provided with a detachable coupling mechanism (hydraulic coupler) with the coupling surface oriented horizontally and horizontally through the elbow pointing in the direction and the vertical hollow pivot joint from the top in order. It is configured so as to be rotatable in the direction and connected to the manifold field from the lateral direction.

また、このローディングアームは、例えばインボードアームの先端部にアウトボードアームを回動するための上部シーブを設け、インボードアームの下端部には下部シーブを設けその間にはワイヤーロープなどの連結材を巻回して、例えばこの下部シーブを駆動装置によって回動駆動することで上部シーブが伝達駆動されてアウトボードアームがインボードアームに対して垂直方向に開閉回動するように構成している。 In addition, this loading arm has, for example, an upper sheave for rotating the outboard arm at the tip of the inboard arm, and a lower sheave at the lower end of the inboard arm, and a connecting material such as a wire rope between them. For example, the lower sheave is rotationally driven by a driving device so that the upper sheave is transmitted and driven so that the outboard arm is opened and closed in a direction perpendicular to the inboard arm.

また、インボードアームの基端部にはバランスウェイトを設けてインボードアームのバランスを保持するバランスウェイト機構を備えている。このバランスウェイト機構は、単に前記バランスウェイトをインボードアームの基端部に移動調整自在に設ける場合だけでなく、例えばアウトボードアームを前述のように開閉回動させる場合には更に下部シーブにアウトボードアームに連動して回動するバランスウェイト取付用アームを設け、このバランスウェイト取付用アームにサブバランスウェイト（可変ウェイト）を設け、これによってアウトボードアームが開閉回動してもこのサブバランスウェイトも連動回動してウェイト重心位置を自動変化させ、アウトボードアームの回動姿勢に応じてこのサブバランスウェイトの重心位置をこのように変化させることで常にバランスを取るように構成する。 Further, a balance weight mechanism is provided at the base end portion of the inboard arm to maintain a balance of the inboard arm by providing a balance weight. This balance weight mechanism not only provides the balance weight at the base end of the inboard arm so that it can be moved and adjusted. However, for example, when the outboard arm is opened and closed as described above, the balance weight mechanism is further moved to the lower sheave. A balance weight mounting arm that rotates in conjunction with the board arm is provided, and a sub balance weight (variable weight) is provided on the balance weight mounting arm so that even if the outboard arm is opened and closed, the sub balance weight is provided. Also, the weight gravity center position is automatically changed by interlocking rotation, and the balance position is always maintained by changing the gravity center position of the sub-balance weight in accordance with the rotation posture of the outboard arm.

また、更にインボードアームやアウトボードアームを夫々所定の方向に所定量回動駆動する駆動装置を油圧駆動装置とし、ジョイント部とジョイント連結部とを連結した荷役作動時には、各油圧駆動装置の油圧駆動を切り、循環切換弁を切り換えて圧油循環管路が形成されるようにすることで、連結後にはこのようにフリーホイールモードに切り換えて、各アームがバランスを取りながら自由に回動自在になると共に各スイベルジョイントによって海上の波によって船舶が揺動してもこれに追従でき、ジョイント部とジョイント連結部との連結部分にこの揺動による負荷がかからないようにしている。 Further, the drive device that drives the inboard arm and the outboard arm to rotate by a predetermined amount in a predetermined direction is a hydraulic drive device, and during the cargo handling operation in which the joint portion and the joint connection portion are connected, the hydraulic pressure of each hydraulic drive device is By switching the drive and switching the circulation switching valve so that the pressure oil circulation pipeline is formed, after connecting, it switches to the free wheel mode in this way, each arm can freely rotate while balancing At the same time, even if the ship is swung by the wave of the sea by each swivel joint, it can follow this, so that the load due to this swinging is not applied to the connecting portion between the joint portion and the joint connecting portion.

このように船舶受渡し用流体荷役装置は、海上の波で船舶が揺れてジョイント部を連結させるジョイント連結部が揺動する状況の中で、このジョイント部を手動若しくは駆動装置の作動（例えば遠隔操作）によって揺動しているジョイント連結部（マニフォールド）に接近させて行き、位置合わせ（移動微調整）してボルト止めや油圧カップラーなどの着脱連結機構によって気密連結させる。 As described above, the ship handling fluid cargo handling apparatus is operated manually or by operating a drive device (for example, remote control) in a situation where the joint connecting part for connecting the joint part is shaken by a wave at sea and the joint part is connected. ) Is moved closer to the swinging joint connecting part (manifold), aligned (moving fine adjustment), and airtightly connected by a detachable connecting mechanism such as a bolt stop or a hydraulic coupler.

しかしながら、このような船舶受渡し用流体荷役装置における連結作業は、常に相対揺動しているなかで行われるため、非常に厄介な作業であり、また熟練を要する。また、波が高かったり風が強いとこの作業は一層困難を極め、作業時間もかなり費やす。 However, the connecting operation in such a ship delivery fluid cargo handling apparatus is always performed while relatively swinging, and is therefore a very troublesome operation and requires skill. Also, if the waves are high or the wind is strong, this work becomes even more difficult and the work time is considerably spent.

湾内や防波堤のある港内では波は抑えられ比較的穏やかな状況での作業となるが、それでも波が高い場合や、また海上の油田やガス田の基地や浮島から直接船舶に荷役する場合やＦＰＳＯ（浮体式海洋石油・ガス生産貯蔵積出設備）と船舶間で荷役する場合などは、波を遮るものがなく波の高い状況、大きな相対揺動の中での作業が強いられることが多いため、この連結作業は非常に厄介で、また作業時間を要する。 In bays and harbors with breakwaters, the waves are suppressed and the operation is relatively calm. However, if the waves are still high, or if the ship is unloaded directly from an oil or gas field base or floating island at sea, or FPSO When handling cargo between a floating offshore oil and gas production and storage facility and a ship, there is nothing to block the waves, and there are many situations where the waves are high and work in a large relative swing is forced. This connecting operation is very troublesome and takes a long time.

桟橋や波止場などの陸上又は油田やガス田の海上基地や浮島などの海上構造物と、タンカーなどの船舶との間や船舶（ＦＰＳＯなども含む）間で、液化天然ガス（ＬＮＧ）や石油などの耐温度性や防火性が要求される流体を荷役する場合、この受け渡し部１の一方側、例えば陸上側やＦＰＳＯに本装置（船舶受渡し用流体荷役装置）を設け、この本装置の先端部（例えばローディングアームのアウトボードアーム４の先端部）のジョイント部５を、他方側、例えば即ち通常の船舶側に設けたジョイント連結部８（マニフォールド）に連結して陸上側やＦＰＳＯの貯蔵タンクから通常の船舶側の貯蔵タンクへと流体を荷役するが、このジョイント部５とジョイント連結部８とを連結する連結作業において、ＦＰＳＯや接岸した船舶は波で揺動しているため、ジョイント部５に対してジョイント連結部８は常に揺動している。 Liquefied natural gas (LNG), oil, etc., between shores such as piers and wharves or offshore structures such as oilfields and gas fields, offshore structures such as floating islands, and ships such as tankers and ships (including FPSO) When handling a fluid that requires high temperature resistance and fire resistance, this apparatus (a ship handling fluid handling apparatus) is provided on one side of the delivery section 1, for example, the land side or FPSO, and the tip of this equipment From the land side or the FPSO storage tank, the joint part 5 (for example, the tip of the outboard arm 4 of the loading arm) is connected to the other side, for example, the joint connecting part 8 (manifold) provided on the normal ship side. Although the fluid is loaded into a normal storage tank on the ship side, in the connecting operation of connecting the joint part 5 and the joint connecting part 8, the FPSO and the ship that touched the shore fluctuated by waves. Because there, the joint connecting portion 8 with respect to the joint portion 5 is constantly swings.

特に防波堤なども無い海上構造物と、これに接岸した船舶との間や船舶間（ＦＰＳＯを含む）で荷役する場合は波が高く大きく揺動している。 In particular, when handling cargo between an offshore structure without a breakwater and a ship berthing on it, or between ships (including FPSO), the waves are high and swinging greatly.

このような状況でジョイント部５をジョイント連結部８に接近操作して位置合わせしてジョイント部５とジョイント連結部８とのフランジ部をボルト止めしたり油圧カップラーなどの着脱連結機構27で連結することとなる。 In such a situation, the joint portion 5 is moved closer to the joint connecting portion 8 to be aligned, and the flange portion between the joint portion 5 and the joint connecting portion 8 is bolted or connected by a detachable connecting mechanism 27 such as a hydraulic coupler. It will be.

本発明は、例えば前述の各油圧駆動装置を駆動（遠隔操作でも良い）させて、例えば貯蔵タンクと連結している立ち上がり管２に対してインボードアーム３を水平旋回させたり垂直方向に伏動回動させつつ、更にアウトボードアーム４を開放回動させるなどして、アウトボードアーム４の先端部に設けたジョイント部５を、波により相対揺動しているジョイント連結部８に接近移動させる。 In the present invention, for example, each of the hydraulic drive units described above is driven (remote operation may be performed), and for example, the inboard arm 3 is swung horizontally with respect to the rising pipe 2 connected to the storage tank, and the inboard arm 3 is tilted in the vertical direction. The joint part 5 provided at the tip of the outboard arm 4 is moved closer to the joint connecting part 8 that is relatively swung by the wave by further rotating the outboard arm 4 while rotating it. .

この際、従来のようにそのままジョイント部５とジョイント連結部８とを接近させて連結させるのではなく、本発明は例えば一旦ジョイント部５若しくはこの周辺部に設けたガイド線体13をジョイント連結部８若しくはこの周辺部に連結して張設し、各アームの油圧駆動装置を荷役作動中と同様にフリーホイールモードに切り換えて各中空回動継手部（スイベルジョイント）によって船舶の揺動に追従し得る状態とし、この状態で、例えばこのガイド線体13を移動駆動機構14としてジョイント部５に設けた巻き取り部24Ａにより巻き取ることで、ガイド線体13を利用してこのガイド線体13に沿う方向にジョイント部５を下降接近移動させる。 At this time, the joint portion 5 and the joint connecting portion 8 are not brought close to each other and connected as in the prior art, but the present invention, for example, connects the guide wire body 13 once provided in the joint portion 5 or its peripheral portion to the joint connecting portion. 8 or connected to this peripheral part and stretched, and the hydraulic drive device of each arm is switched to the free wheel mode in the same manner as the cargo handling operation, and the swing of the ship is followed by the swivel joint part (swivel joint). In this state, for example, the guide wire body 13 is wound up by the winding portion 24A provided in the joint portion 5 as the movement drive mechanism 14, so that the guide wire body 13 is used to guide the guide wire body 13 to the guide wire body 13. The joint part 5 is moved downward and approached along the direction.

即ち、このガイド線体13を張設状態とすると共にフリーホイールモードに切り換えることで、ジョイント部５に対するジョイント連結部８の揺動はなくなるか殆んどなくなる状態で、このガイド線体13を巻き取ることでジョイント部５を下降接近移動駆動させる構成としている。 In other words, the guide wire 13 is wound in a state where the guide wire 13 is stretched and switched to the free wheel mode so that the joint connecting portion 8 does not swing or almost disappears with respect to the joint 5. By taking it, it is set as the structure which drives the joint part 5 to descent | fall approaching movement.

従って、本発明はこの状態でガイド線体13を利用して接近移動でき、しかも上方から下降接近移動させて連結面を下向きに設けたジョイント部５を、連結面を上向きに設けたジョイント連結部８に上下方向からこの連結面同士を合致させて連結することができる。 Accordingly, the present invention can be moved closer by using a guide wire 13 in this state, moreover joint connecting portion provided with a joint portion 5 provided in the downward joint face is lowered moved closer from the top, upwardly coupling surface The connecting surfaces can be connected to 8 in the vertical direction.

即ち、上方からガイド線体13を利用して下降接近させてこの上下方向から連結面同士を合致させて連結させることができ、連結作業が容易にしてスピーディーに安全に行える。 That is, the guide wire 13 can be lowered and approached from above and the connecting surfaces can be connected in the vertical direction so that the connecting work can be facilitated and speedy and safe.

また、例えば更にバランスウェイト機構７をオーバーバランス状態に設定した構成とすることで、常にジョイント部５は持ち上げ付勢されガイド線体13に張設付勢を生じさせる構成となることから、波による揺動によってこのガイド線体13はたるみにくくガイド線体13のガイド機能は損なわれにくく、また、常にこの持ち上げ付勢された状態でこのガイド線体13を例えば巻き取り部24Ａで巻き取ってジョイント部５を接近移動させるため、この移動作業が一層スムーズにして安定性良く行われ安全に接近移動できるなど、連結作業が極めて容易にしてスピーディーに行うことができ、またこの連結作業に人の関与を少なくできそれだけ安全性が向上する画期的な船舶受渡し用流体荷役装置となる。 Further, for example, by further configuring the balance weight mechanism 7 in an overbalanced state, the joint portion 5 is always lifted and biased, and the guide wire body 13 is stretched and biased. The guide wire 13 is not easily slackened due to the swinging, and the guide function of the guide wire 13 is not easily lost. In addition, the guide wire 13 is wound up by, for example, the winding portion 24A in a state of being always lifted and biased. Since the moving part 5 is moved closer, this moving work is smoother, more stable and can be moved closer and more safely, and the connecting work can be performed very easily and speedily. It is an epoch-making fluid handling device for ship delivery that can reduce the amount of safety and improve safety.

即ち、波が大きかったり、波の変化が激しく波の揺動に追従できずにガイド線体13がゆるむことがあるが、本発明はこのような場合でもジョイント部５はウェイトバランス機構７がオーバーバランス状態に設定されていることで、ジョイント部５は常に持ち上げ付勢されているため、この持ち上げ付勢がガイド線体13の張力となり緩みにくくなる。即ち、このバランスウェイト機構７によるオーバーバランス状態による持ち上げ付勢によって波の揺動にスピーディーに追従して緩みにくくなる。 In other words, the guide wire 13 may loosen because the wave is large or the wave change is so strong that it cannot follow the wave oscillation. Since the joint portion 5 is always lifted and biased by being set in the balanced state, this lifting bias becomes tension of the guide wire body 13 and is not easily loosened. That is, the lifting and biasing force in the overbalance state by the balance weight mechanism 7 makes it less likely to loosen following the wave oscillation speedily.

更に説明すれば、例えばバランスウェイト機構７によって前記オーバーバランス状態に保持されているアウトボードアーム４の先端部に設けたジョイント部５を各アームの駆動装置を作動させて、例えば下方のジョイント連結部８の真上に位置するところまで接近移動させた後に、フリーホイールモードに切り換えると共に、例えばこのジョイント部５若しくはこの周辺部に設けたガイド線体13の垂下端をジョイント連結部８若しくはその周辺部に連結し、例えば移動駆動機構14としてジョイント部５に設けた巻き取り部24Ａを巻き取り作動させてガイド線体13を巻き取ることで、このガイド線体13を張設すると共にジョイント部５をジョイント連結部８に巻き取り接近移動させる。 More specifically, for example, the joint unit 5 provided at the distal end portion of the outboard arm 4 held in the overbalanced state by the balance weight mechanism 7 is operated by driving the driving device of each arm, for example, the lower joint connecting portion. After moving close to the position directly above 8, the mode is switched to the free wheel mode, and for example, the hanging end of the guide wire 13 provided at the joint 5 or the peripheral portion thereof is connected to the joint connecting portion 8 or the peripheral portion thereof. For example, the guide wire 13 is wound by operating the take-up portion 24A provided on the joint portion 5 as the movement drive mechanism 14 to take up the guide wire 13, and the joint portion 5 is stretched. The joint connecting portion 8 is wound up and moved.

この場合には、この移動駆動機構14（巻き取り部24Ａ）の作動によって前記バランスウェイト機構７による持ち上げ付勢に抗してインボードアーム３を傾動しつつアウトボードアーム４を開放回動してジョイント部５を下降させることとなる。 In this case, the operation of the moving drive mechanism 14 (winding portion 24A) causes the inboard arm 3 to tilt while the outboard arm 4 is tilted against the lifting bias by the balance weight mechanism 7 to open and rotate. The joint part 5 is lowered.

また、例えば、このようにガイド線体13を利用して接近移動させる際に、このガイド線体13に沿って移動自在に設けた移動係合部20をジョイント部５に設け、このジョイント部５を接近移動させつつガイド線体13に沿って移動する移動係合部20をジョイント連結部８側に設けた位置決め係合受部19に係合させて位置決め状態とし、この位置決め状態で近接させたジョイント部５とジョイント連結部８とを油圧カップラーなどにより気密状態に連結（油圧カップリング）する。 Further, for example, when the guide wire 13 is used to move closer, the moving engagement portion 20 provided so as to be movable along the guide wire 13 is provided in the joint portion 5. The moving engagement portion 20 that moves along the guide wire body 13 while being moved closer is engaged with a positioning engagement receiving portion 19 provided on the joint connecting portion 8 side to be in a positioning state, and is brought close in this positioning state. The joint portion 5 and the joint connecting portion 8 are connected in an airtight state (hydraulic coupling) by a hydraulic coupler or the like.

このように本発明ではバランスウェイト機構７によってほぼバランスを取りながらも例えばオーバーバランス状態として持ち上げ付勢されているジョイント部５側から垂設されているガイド線体13を仮連結して張設した状態とし、且つこの常に持ち上げ付勢されていることによって常に張設した状態でのガイド線体13を巻き取るなどしてジョイント部５を接近移動させる構成とすれば、波の揺動が大きくても激しくてもガイド線体13はゆるみにくく、このゆるみにくい状態で張設されたガイド線体13を持ち上げ付勢に抗しつつ巻き取ることで、上方から下方のジョイント連結部８にジョイント部５を下降接近させて上下方向からこの連結面同士を合致させて連結でき、容易にしてスピーディーに安全に連結作業が行え、またこの連結作業に人の関与を少なくできそれだけ一層安全性が向上することとなる。 Thus, in the present invention, the guide wire body 13 suspended from the joint portion 5 side that is lifted and biased, for example, in an overbalanced state while being substantially balanced by the balance weight mechanism 7 is temporarily connected and stretched. If the configuration is such that the joint portion 5 is moved closer by winding the guide wire body 13 in a state where it is always lifted and biased and is always stretched, the oscillation of the wave is large. The guide wire 13 is difficult to loosen even if it is intense, and the guide wire 13 stretched in this difficult to loosen state is lifted and wound up against the urging force, so that the joint 5 Can be connected by aligning the connecting surfaces from above and below in the downward direction, allowing easy and speedy and safe connection work. Much can reduce the grant becomes possible to improve even more safety.

また、本発明は、ジョイント部５に緊急時に流体を遮断し離脱させる緊急流体遮断離脱装置17を設けると共に、この緊急流体遮断離脱装置17が作動した際にガイド線体13の連結部、例えばガイド線体13の垂下端と前記ジョイント連結部８若しくはジョイント連結部８の周辺部との連結部に所定以上の負荷が加わったとき緊急時と判断し自動的に油圧や電力あるいはメカ的に連結を切り離すガイド線体緊急切り離し機構を設けて更に安全性を高めている。 The present invention also Rutotomoni provided an emergency fluid cutoff withdrawal device 17 which blocks the fluid in an emergency to the joint portion 5 withdrawal connection portion of the guide wire 13 when the emergency fluid cutoff withdrawal device 17 is actuated, e.g. When a load of a predetermined level or more is applied to the connecting portion between the hanging end of the guide wire 13 and the joint connecting portion 8 or the peripheral portion of the joint connecting portion 8, it is judged as an emergency and automatically connected hydraulically, electric power or mechanically. further to enhance the safety by providing a guide wire body emergency disconnect mechanism to disconnect the.

また、本発明では、船側のジョイント連結部８側には中空回動継手部15を追加することなく、三方向の中空回動継手15Ａ，15Ｂ，15Ｃの配置改良と、エルボ16の形状改良によって安定性良くスムーズに三方向にジョイント部５を回動自在にして連結面を下向きに構成でき、一層実用性に優れる。 Further, according to the present invention, without adding the hollow rotary joint 15 on the side of the joint joint 8 on the ship side, the arrangement of the three-way hollow rotary joints 15A, 15B, 15C and the shape of the elbow 16 are improved. The joint portion 5 can be freely rotated in three directions with good stability and the connecting surface can be configured to face downward.

After the joint portion 5 provided at the tip portion is moved closer to, for example, a position directly above the lower joint connecting portion 8, the hydraulic drive device of the inboard arm 3 other than the hydraulic drive device 29 is also freewheel. In addition to switching to the mode, the guide wire 13 provided in the joint portion 5 (exactly, the guide wire unwound from the winding portion 24A (winding winch) provided in the proximity portion (peripheral portion) connected to the joint portion 5) The body 13 (winding wire)) is connected to the periphery of the joint connecting portion 8, for example, the peripheral portion of the joint portion 5 as the movement drive mechanism 14. By operating the winding and the winding portion 24 A provided by winding the guide wire 13, the additional winding while stretched the guide wire 13 to the joint portion 5 to the joint connecting portion 8 It is set as the structure which winds up and moves.

即ち、本実施例では、このようなこのジョイント部５若しくはこの周辺部と前記ジョイント連結部８若しくはこのジョイント連結部８の周辺部との間に前記巻き取り部24Ａによって張設するガイド線体13と、このガイド線体13を巻き取り部24Ａによって巻き取ることでこの巻き取り部24Ａを設けた側の前記ジョイント部５を前記ジョイント連結部８に下降接近移動させる移動駆動機構14とを備えた構成としている。 That is, in the present embodiment, the guide wire 13 stretched by the winding portion 24A between the joint portion 5 or its peripheral portion and the joint connecting portion 8 or the peripheral portion of the joint connecting portion 8 in this embodiment.

このジョイント部５のジョイント連結部８への接近移動は、前述のようにガイド線体13をジョイント部５とジョイント連結部８側の間に張設した後、各アームを回動駆動させる油圧駆動装置をフリーホイールモードにして各回動継手部によって波による相対移動に追従するようにし、この各回動継手部によって波に追従して相対的にほとんど静止した状態とし、この状態で前記移動駆動機構14として設けたジョイント部５の巻き取り装置24Ａを巻き取り作動させて、このガイド線体13を巻き取ることで、各アームを回動させつつ前記持ち上げ付勢に抗してジョイント部５を下降駆動させる構成としている。 The approaching movement of the joint portion 5 to the joint connecting portion 8 is performed by hydraulic drive in which the guide wire 13 is stretched between the joint portion 5 and the joint connecting portion 8 side as described above, and each arm is rotated. The apparatus is set to a free wheel mode so as to follow the relative movement caused by the waves by each of the rotary joints, and is made to be in a relatively stationary state following the waves by each of the rotary joints. The winding device 24A of the joint portion 5 provided as a winding is operated to wind up the guide wire 13 so that the joint portion 5 is driven to descend against the lifting bias while rotating each arm. The configuration is to let

従って、波の激しい揺動によってガイド線体13が緩むときも、スピーディーに追従してバランスウェイト機構７による持ち上げ付勢されているジョイント部５が上昇してガイド線体13の緩みを吸収し、ガイド線体13は緩みにくく、一層容易にしてスピーディーに連結作業ができることとなる。 Therefore, even when the guide wire body 13 is loosened due to a strong wave swing, the joint portion 5 lifted and urged by the balance weight mechanism 7 follows the speed, and absorbs the looseness of the guide wire body 13. The guide wire body 13 is less likely to loosen and can be connected more easily and speedily.
