Description

本発明は、吊り装置に関する。 The present invention relates to a suspension device.

従来から、吊り装置などによりコンクリートブロック（以下、単に被牽吊体ともいう）などを牽吊して、水中への構造物の設置や水底の造成などを行っている。こうした水中へ被牽吊体を牽吊する吊り具が、例えば下記の特許文献１などに開示されて公知である。 Conventionally, a concrete block (hereinafter, also simply referred to as a suspended body) or the like has been suspended by a suspending device or the like to install a structure in water or to create a water bottom. Such a hanging tool for suspending the suspended body in water is disclosed and known in, for example, Patent Document 1 below.

上記のように水中へ被牽吊体を牽吊する吊り具として、例えば図８に示す構成のものがある。 As a hanging tool for suspending the suspended body in water as described above, for example, there is one having the configuration shown in FIG.

即ち、吊り具８０は、作業船などのクレーンから水中に吊り下げられた主巻ＭＷに連結され、且つ被牽吊体Ｊと接続された玉掛けワイヤーＴＷを支持する鉤型のフック支持体８１と、先端がクレーンから水中に吊り下げた補巻ＳＷに連結され、フック支持体８１の開口部８１ａを閉鎖することにより玉掛けワイヤーＴＷの外れ止め機能を発揮する外れ止めレバー８２を有している。 That is, the hanger 80 is connected to the main winding MW suspended in water from a crane such as a work boat, and is connected to a hook-shaped hook support 81 that supports a sling wire TW connected to the suspended body J. It has a retaining lever 82 whose tip is connected to a supplementary winding SW suspended from a crane in water and which functions to prevent the sling wire TW from coming off by closing the opening 81a of the hook support 81.

外れ止めレバー８２は、補巻ＳＷを上げ操作することにより、フック支持体８１の開口部８１ａを開放して玉掛けワイヤーＴＷを取外すことが可能な構成とされている。またフック支持体８１には浮体８３が連結されており、フック支持体８１の開口部８１ａが開放されると、浮体８３の浮力によりフック支持体８１が玉掛けワイヤーＴＷを取外す方向に回転する構成とされている。 The retaining lever 82 has a configuration in which the slinging wire TW can be removed by opening the opening 81a of the hook support 81 by raising the auxiliary winding SW. A floating body 83 is connected to the hook support 81, and when the opening 81a of the hook support 81 is opened, the hook support 81 rotates in the direction of removing the sling wire TW due to the buoyancy of the floating body 83. Has been done.

したがって、被牽吊体Ｊが水底に着底した後に行う玉外し作業を、潜水士が行う必要が殆ど無くなる。 Therefore, it is almost unnecessary for the diver to perform the ball removing work after the suspended body J has landed on the bottom of the water.

特許第５７３１３１１号公報Japanese Patent No. 5731311

しかし、上記した吊り具８０は、クレーンに接続された主巻ＭＷと補巻ＳＷの両方の操作を行わなければならず、操作性が悪い。 However, the above-mentioned hanger 80 has to operate both the main winding MW and the auxiliary winding SW connected to the crane, and the operability is poor.

また、フック支持体８１から玉掛けワイヤーＴＷを外した後、吊り具８０を引き揚げる際に、図８に示すように主巻ＭＷと補巻ＳＷは近接状態にあるため、両者が絡まってしまうなどの問題がある。 Further, when the sling wire TW is removed from the hook support 81 and then the hanger 80 is pulled up, the main winding MW and the auxiliary winding SW are in a close state as shown in FIG. 8, so that they are entangled with each other. There's a problem.

上記の点から吊り具には主巻又は補巻きのいずれか一のみが接続され、且つフック支持体の開口部の閉鎖状態を解除する作業を無線による遠隔操作により行うことが良好であるが、そうした技術は見聞きしないし開示もされていない。 From the above point, it is preferable that only one of the main winding and the auxiliary winding is connected to the hanging tool, and the work of releasing the closed state of the opening of the hook support is performed by wireless remote control. Such technology has not been seen or heard and has not been disclosed.

本発明の目的は、主巻又は補巻きの何れか一のみと連結され、無線による遠隔操作によりフック支持体の開口部の閉鎖状態を解除可能な装置を提供することにある。 An object of the present invention is to provide a device that is connected to only one of the main winding and the auxiliary winding and can release the closed state of the opening of the hook support by wireless remote control.

The annular portion 21 of the hook support 2 of the present embodiment is connected to the main winding MW, but the present invention is not limited to this, and the annular portion 21 may be connected to the auxiliary winding. That is, the annular portion 21 is connected to only one of the main winding MW and the auxiliary winding. A retaining portion 3 is integrally connected to the arrow Y2 side of the base portion 22 of the hook support 2. The lower half portion of the retaining portion 3 is formed to be tapered, and an inclined surface 3a that rises rearward (in the direction of arrow X1) is formed. The hook support 2 and the retaining portion 3 are attached so that the tip portions thereof are inclined outward (forward (arrow X2)) so that the front view is substantially square-shaped.

フック部材４は、フック支持体２と外れ止め部３の間に支軸４３により回動自在に連結されている。フック部材４は、アーム部４１と支持部４２とが略釣り針形状に一体形成され、アーム部４１と支持部４２とは略同一平面内に配置されている。アーム部４１の上部には厚さ方向の途中部を切欠いてなる左右１対のブラケット部４１ａが形成され、左右のブラケット部４１ａの上部間には支軸４３が架設状に設けられている。 The hook member 4 is rotatably connected between the hook support 2 and the retaining portion 3 by a support shaft 43. In the hook member 4, the arm portion 41 and the support portion 42 are integrally formed in a substantially fishing hook shape, and the arm portion 41 and the support portion 42 are arranged in substantially the same plane. A pair of left and right bracket portions 41a are formed on the upper portion of the arm portion 41 so as to cut out an intermediate portion in the thickness direction, and a support shaft 43 is provided erected between the upper portions of the left and right bracket portions 41a.

支持部４２は半円弧形状に形成され、玉掛けワイヤーＴＷを安定して受け止めることができるように構成されている。 The support portion 42 is formed in a semi-circular shape so that the sling wire TW can be stably received.

支持部４２の先端部は略円柱状に形成され、上端部には後方上がりの傾斜面４２ａが形成されている。この傾斜面４２ａと外れ止め部３の傾斜面３ａとが当接されると、フック部材４の開口部４ａが閉鎖される。 The tip end portion of the support portion 42 is formed in a substantially columnar shape, and the rearward rising inclined surface 42a is formed at the upper end portion. When the inclined surface 42a and the inclined surface 3a of the retaining portion 3 come into contact with each other, the opening 4a of the hook member 4 is closed.

閉鎖解除手段５は、図２〜図４に示すように、アーム部４１の厚さ方向の途中部を切り欠いた切欠き部内で左右のブラケット部４１ａの間に配置される。閉鎖解除手段５は、枢支ピン５０を介してフック部材４に回転自在に支持したロック部材５１と、ロック部材５１をロック側（矢印Ｋ側）へ常時付勢する付勢手段５２とを備えている。 As shown in FIGS. 2 to 4, the closing release means 5 is arranged between the left and right bracket portions 41a in a notch portion in which an intermediate portion in the thickness direction of the arm portion 41 is cut out. The closing release means 5 includes a lock member 51 rotatably supported by the hook member 4 via a pivot pin 50, and an urging means 52 that constantly urges the lock member 51 to the lock side (arrow K side). ing.

ロック部材５１は、フック支持体２の基部２２に形成された止め部としての係合突部２３に係合してフック部材４を閉鎖位置と開放位置に保持するロック部５１ａと、係合突部２３とロック部５１ａとの係合を解除操作する操作部５１ｂを有している。係合突部２３は、フック支持体２の基部２２の後方側で且つ支軸４３付近に、外方へ突出する様態で形成されている。 The lock member 51 engages with an engaging protrusion 23 as a stopper formed on the base 22 of the hook support 2 to hold the hook member 4 in the closed position and the open position, and the engaging protrusion 51a. It has an operation portion 51b for disengaging the engagement between the portion 23 and the lock portion 51a. The engaging protrusion 23 is formed on the rear side of the base 22 of the hook support 2 and in the vicinity of the support shaft 43 so as to project outward.

ロック部５１ａは、ロック部材５１の上半前部に基部２２の後方面側へ延在する様態に形成され、操作部５１ｂは、ロック部材５１の下半後部にブラケット部４１ａから後方（矢印Ｘ１）へ突出する様態に形成されている。図示例のロック部５１ａと操作部５１ｂは、互いに交差する形状に形成されている。 The lock portion 51a is formed in the upper half front portion of the lock member 51 so as to extend toward the rear surface side of the base portion 22, and the operation portion 51b is rearward (arrow X1) from the bracket portion 41a in the lower half rear portion of the lock member 51. ) Is formed so as to protrude. The lock portion 51a and the operation portion 51b in the illustrated example are formed so as to intersect each other.

枢支ピン５０には捩りバネからなる付勢手段５２が外装され、付勢手段５２の一端部はロック部材５１に掛け止めされ、他端部はフック部材４に掛け止められている。ロック部材５１は、付勢手段５２により、ロック部５１ａの先端部がフック支持体２の基部２２の後方面に当接するように、図３に矢印Ｋ（ロック側）で示す方向へ常時付勢されている。 A urging means 52 made of a torsion spring is externally attached to the pivot pin 50, one end of the urging means 52 is hooked to the lock member 51, and the other end is hooked to the hook member 4. The lock member 51 is constantly urged by the urging means 52 in the direction indicated by the arrow K (lock side) in FIG. 3 so that the tip end portion of the lock portion 51a abuts on the rear surface of the base portion 22 of the hook support 2. Has been done.

図３に示すように、フック部材４が閉鎖位置にあるとき、ロック部５１ａが枢支ピン５０の略直上位置において係合突部２３に係合し、フック部材４の開放位置側への回動が確実に規制されて、フック部材４の閉鎖位置が保持される。更に云うとロック部５１ａの先端部が係合突部２３の下面と当接している場合には、フック部材４の閉鎖状態が保持される。また、後述するが図４（Ｃ）に示すように、フック部材４を開放位置へ操作して、ロック部５１ａの先端部が係合突部２３の上面と当接している場合には、フック部材４の開放状態が保持される。 As shown in FIG. 3, when the hook member 4 is in the closed position, the lock portion 51a engages with the engaging protrusion 23 at a position substantially directly above the pivot pin 50, and the hook member 4 is rotated toward the open position side. The movement is reliably regulated and the closed position of the hook member 4 is maintained. Furthermore, when the tip of the lock portion 51a is in contact with the lower surface of the engaging protrusion 23, the closed state of the hook member 4 is maintained. Further, as will be described later, as shown in FIG. 4C, when the hook member 4 is operated to the open position and the tip portion of the lock portion 51a is in contact with the upper surface of the engaging protrusion 23, the hook is hooked. The open state of the member 4 is maintained.

アクチュエータ部６は、ケーシング内を移動して伸縮可能なロッド部６１と、細示することは省略したがロッド部６１を伸縮移動させる駆動部と、駆動部を駆動させる遠隔操作手段７からの駆動信号を受信する受信部とを有している。 The actuator unit 6 is driven by a rod unit 61 that can move in the casing and expand and contract, a drive unit that expands and contracts the rod unit 61, although not shown in detail, and a remote control means 7 that drives the drive unit. It has a receiving unit that receives a signal.

駆動部は、モータであってもバネ材であっても良いが、手動でもロッド部６１の伸縮を操作可能なラッチロック式のバネ材が好ましい。駆動部は受信部から駆動信号を受け取るとロッド部６１を駆動させる。 The drive unit may be a motor or a spring material, but a latch lock type spring material that can manually expand and contract the rod unit 61 is preferable. When the drive unit receives the drive signal from the receiving unit, the drive unit drives the rod unit 61.

アクチュエータ部６は、ロッド部６１が伸張するとロック部材５１の操作部５１ｂを押圧し（押し下げ）てロック解除側（矢印Ｋ２側）へ回動可能な位置に配置されている（図４（Ａ）参照）。図示例では、操作部５１ｂの直上側（矢印Ｙ１側）である。図示例の限りではなく、操作部５１ｂの直下側に取付けて実施することも可能である。 The actuator portion 6 is arranged at a position where it can rotate to the unlock side (arrow K2 side) by pressing (pushing down) the operation portion 51b of the lock member 51 when the rod portion 61 extends (FIG. 4 (A)). reference). In the illustrated example, it is directly above the operation unit 51b (arrow Y1 side). Not limited to the illustrated example, it is also possible to mount the operation unit 51b directly below the operation unit 51b.

遠隔操作手段７は、アクチュエータ部６のロッド部６１へ無線により駆動信号を発信して、ロッド部６１の伸張移動又は収縮移動を行わせる。遠隔操作手段７は、図１に示すように操作部７１と、発信部７２と、切替部７３を有している。 The remote control means 7 wirelessly transmits a drive signal to the rod portion 61 of the actuator portion 6 to extend or contract the rod portion 61. As shown in FIG. 1, the remote control means 7 has an operation unit 71, a transmission unit 72, and a switching unit 73.

操作部７１は、作業者が閉鎖解除操作を行う入力部などを備えた操作盤である。発信部７２は、操作部７１からの入力信号に基づいてロッド部６１を伸張動作又は収縮動作させる駆動信号を発信する。発信部７２が発信する駆動信号は、電波又は音波である。音波とは、超音波を含む。切替部７３は、発信部７２により発信させる駆動信号を電波と音波の何れか一に切替える。切替え作業は、作業者が操作部７１を操作して切替えてよい。 The operation unit 71 is an operation panel provided with an input unit or the like for an operator to perform a closing release operation. The transmission unit 72 transmits a drive signal for extending or contracting the rod unit 61 based on the input signal from the operation unit 71. The drive signal transmitted by the transmitting unit 72 is a radio wave or a sound wave. The sound wave includes an ultrasonic wave. The switching unit 73 switches the drive signal transmitted by the transmitting unit 72 to either radio waves or sound waves. The switching operation may be switched by the operator operating the operation unit 71.

特に吊り具１（特にはアクチュエータ部６）が水中にある場合には、超音波による駆動信号を発生させ、吊り具１が水中以外（水上）にある場合、電波による駆動信号を発生させる。 In particular, when the hanger 1 (particularly the actuator unit 6) is underwater, a drive signal by ultrasonic waves is generated, and when the hanger 1 is outside the water (on the water), a drive signal by radio waves is generated.

浮体８は、内部に気体を充填して浮力を得るフロート材、又は発泡スチロールなどの水より比重の軽いフロート材でありフック部材４と連結されている。特にフック部材４の下半部を構成する支持部４２に紐体などを介して連結されることが好ましい。また、支持部４２に接合されていても良い。 The floating body 8 is a float material that is filled with gas to obtain buoyancy, or a float material having a specific gravity lighter than that of water such as styrofoam, and is connected to the hook member 4. In particular, it is preferable that the hook member 4 is connected to the support portion 42 constituting the lower half portion via a string or the like. Further, it may be joined to the support portion 42.

浮体８は、外れ止め部３によるフック部材４の開口部４ａの閉鎖状態がアクチュエータ部６により解除されると、浮力によりフック部材４を玉掛けワイヤーＴＷを外す方向（矢印Ｋ３方向）へ移動させる。 When the closing state of the opening 4a of the hook member 4 by the retaining portion 3 is released by the actuator portion 6, the floating body 8 moves the hook member 4 in the direction of removing the sling wire TW (in the direction of arrow K3) by buoyancy.

本実施形態の浮体８は、細示することは省略したが浮力を調整する手段を有している。浮力を調整する手段とは、例えば潜水士の呼気を浮体８に設けられた注入口から適切な量注入する、又は浮体８に外力を加えることで当該注入口から気体を抜いて浮力を調整する方法がある。また、気体を注入する方法としては、浮体８に注入ホースを取付けておき、潜水士のエアーホースと注入ホースとを接続して、エアーホースから気体を注入する方法を実施しても良い。 The floating body 8 of the present embodiment has a means for adjusting the buoyancy, although not shown in detail. The means for adjusting the buoyancy is, for example, injecting an appropriate amount of exhaled breath of a diver from an injection port provided in the floating body 8, or by applying an external force to the floating body 8 to remove gas from the injection port and adjust the buoyancy. There is a way. Further, as a method of injecting gas, a method of injecting gas from the air hose by attaching an injection hose to the floating body 8 and connecting the diver's air hose and the injection hose may be carried out.

上記したように本実施形態の吊り装置１００Ａは、遠隔操作手段７によりアクチュエータ部６のロッド部６１が伸張動作し、ロッド部６１の伸張動作に連動して閉鎖解除手段５の操作部５１ｂが押圧されてロック解除側へ回動することで、フック部材４の閉鎖状態が解除される。吊り装置１００Ａは、フック部材４の閉鎖状態が解除されると、フック部材４が浮体８の浮力により支軸４３を中心に上方へ回動して、玉掛けワイヤーＴＷを自動で取外すことができる。 As described above, in the suspension device 100A of the present embodiment, the rod portion 61 of the actuator portion 6 is extended by the remote control means 7, and the operation portion 51b of the closing release means 5 is pressed in conjunction with the extension operation of the rod portion 61. Then, the hook member 4 is released from the closed state by rotating to the unlocked side. When the closed state of the hook member 4 is released, the hanging device 100A can automatically remove the sling wire TW by rotating the hook member 4 upward around the support shaft 43 by the buoyancy of the floating body 8.

また、本実施形態の吊り装置１００Ａを構成する遠隔操作手段７は、駆動信号を電波と音波のいずれか一に切替える切替部を有している。 Further, the remote control means 7 constituting the suspension device 100A of the present embodiment has a switching unit for switching the drive signal to either radio waves or sound waves.

したがって、例えば水底の深瀬から浅瀬に向かってコンクリートブロックなどの被牽吊体Ｊを順に据付けしていく際に、深瀬において吊り具１などが水中にある場合には、音波による駆動信号を発信する。浅瀬になり吊り具１（特にアクチュエータ部６）が水上に存在してきた場合には、発信する駆動信号を電波に切替えることで、据付作業を止めることなく連続して行うことができる。つまり、本実施形態の吊り装置１は、水陸兼用にできる利点がある。 Therefore, for example, when the suspended body J such as a concrete block is installed in order from the deep water on the bottom of the water to the shallow water, if the suspension tool 1 or the like is underwater in the deep water, a drive signal by sound waves is transmitted. .. When the hanger 1 (particularly the actuator portion 6) is present on the water in a shallow water, the drive signal to be transmitted can be switched to radio waves so that the installation work can be continuously performed without stopping. That is, the suspension device 1 of the present embodiment has an advantage that it can be used for both land and water.

なお、フック支持体２とフック部材４とは、フック部材４が開放方向に付勢力を発揮するように配置された付勢手段により接続されていてよい。すると、本実施形態の吊り具１を水上位置で使用する際に、浮体８の浮力が働かない場合であってもフック部材４の閉鎖状態が解除されると、上記した付勢手段によりフック部材が支軸４３を中心に上方へ回動して、玉掛けワイヤーＴＷを自動で取外すことが容易にできる。また、上記の付勢手段を設けなくても、フック部材４の重心をずらしておき、フック部材４の閉鎖状態が解除されると、フック部材４が自動的に支軸４３を中心に上方へ回動する構成を有していてよい。 The hook support 2 and the hook member 4 may be connected by an urging means arranged so that the hook member 4 exerts an urging force in the opening direction. Then, when the hanger 1 of the present embodiment is used in the water position, even if the buoyancy of the floating body 8 does not work, when the closed state of the hook member 4 is released, the hook member is released by the above-mentioned urging means. Rotates upward around the support shaft 43, and the sling wire TW can be easily removed automatically. Further, even if the above-mentioned urging means is not provided, the center of gravity of the hook member 4 is shifted, and when the closed state of the hook member 4 is released, the hook member 4 automatically moves upward about the support shaft 43. It may have a rotating configuration.

＜動作＞
次に、図３、図４を参照しながら本実施形態の吊り装置１００Ａ、特に吊り具１の動作を簡潔に説明する。図３に示す吊り具１は、フック部材４が外れ止め部３により開口部４ａが閉鎖されている状態を示している。 <Operation>
Next, the operation of the suspension device 100A of the present embodiment, particularly the suspension tool 1, will be briefly described with reference to FIGS. 3 and 4. The hanger 1 shown in FIG. 3 shows a state in which the hook member 4 has the opening 4a closed by the retaining portion 3.

図３において吊り具１は、玉掛けワイヤーＴＷにより被牽吊体Ｊを水中へ吊り下げている状態である。被牽吊体Ｊが水底に着底すると、潜水士は携帯している水中電話などで船上にいる作業者にフック部材４の閉鎖状態を解除するよう指示する。すると作業者は、遠隔操作手段７の操作部７１を操作して、発信部７２によりアクチュエータ部６のロッド部６１を伸張動作させる駆動信号を音波（又は超音波）で発信させる。 In FIG. 3, the suspending tool 1 is in a state in which the suspended body J is suspended in water by a sling wire TW. When the suspended body J has landed on the bottom of the water, the diver instructs the operator on the ship to release the closed state of the hook member 4 by using a portable underwater telephone or the like. Then, the operator operates the operation unit 71 of the remote control means 7 to transmit a drive signal by the transmission unit 72 to extend the rod portion 61 of the actuator unit 6 by sound waves (or ultrasonic waves).

アクチュエータ部６の受信部が駆動信号を受け取ると、駆動部はロッド部６１を伸張動作させる。すると、図４（Ａ）に示すようにロッド部６１は、直下位置に配置されたロック部材５１の操作部５１ｂを押し下げて、枢支ピン５０を中心に閉鎖解除方向（矢印Ｋ２方向）へ回動させる。するとロック部材５１のロック部５１ａは、係合突部２３から離脱して、フック部材４の外れ止め部３による閉鎖状態が解除される。 When the receiving unit of the actuator unit 6 receives the drive signal, the drive unit extends the rod unit 61. Then, as shown in FIG. 4A, the rod portion 61 pushes down the operation portion 51b of the lock member 51 arranged at the position directly below and rotates around the pivot pin 50 in the closing release direction (arrow K2 direction). Move it. Then, the lock portion 51a of the lock member 51 is disengaged from the engaging protrusion 23, and the closed state by the disengagement prevention portion 3 of the hook member 4 is released.

次に、閉鎖状態が解除されたフック部材４は、図４（Ｂ）に示すように浮体８の浮力により支軸４３を中心に上方（矢印Ｋ３方向）へ回動して、玉掛けワイヤーＴＷを自動で取外すことができる。 Next, the hook member 4 whose closed state is released rotates upward (in the direction of arrow K3) about the support shaft 43 by the buoyancy of the floating body 8 as shown in FIG. 4 (B), and slings the sling wire TW. It can be removed automatically.

しかる後に、例えば数秒後に遠隔操作手段７の発信部７２は、アクチュエータ部６のロッド部６１を収縮動作させる駆動信号を音波（又は超音波）で発信させる。すると、図４（Ｃ）に示すように、アクチュエータ部６のロッド部６１がロック部５１ａと反対側へ移動して、ケーシング内に収納される。そしてロッド部６１からの押圧力が無くなったロック部５１ａは、付勢手段５２によりロック側方向（矢印Ｋ方向）に移動して、先端部が係合突部２３の上面と当接する。すると、フック部材４の開放状態が保持される。 After that, for example, after a few seconds, the transmitting unit 72 of the remote control means 7 transmits a drive signal for contracting the rod portion 61 of the actuator unit 6 by sound waves (or ultrasonic waves). Then, as shown in FIG. 4C, the rod portion 61 of the actuator portion 6 moves to the side opposite to the lock portion 51a and is housed in the casing. Then, the lock portion 51a from which the pressing force from the rod portion 61 is eliminated is moved in the lock side direction (arrow K direction) by the urging means 52, and the tip portion abuts on the upper surface of the engaging protrusion 23. Then, the open state of the hook member 4 is maintained.

アクチュエータ部６のロッド部６１の収縮動作は、遠隔操作手段７を介することなくアクチュエータ部６の駆動部が伸張動作をしてから一定時間後に動作させる設定としてもよい。 The contraction operation of the rod portion 61 of the actuator unit 6 may be set to operate after a certain period of time from the extension operation of the drive unit of the actuator unit 6 without the intervention of the remote control means 7.

上記したように本実施形態の吊り装置１００Ａは、フック部材４の閉鎖状態の解除を、遠隔操作手段７により駆動するロッド部６１の伸張動作により行い、閉鎖解除となったフック部材４を浮体８の浮力により支軸４３を中心に上方に回転移動させて、フック部材４に掛けられた玉掛けワイヤーＴＷを自動的に取外すことができる。 As described above, in the suspension device 100A of the present embodiment, the closed state of the hook member 4 is released by the extension operation of the rod portion 61 driven by the remote control means 7, and the hook member 4 released from the closure is released by the floating body 8. The sling wire TW hung on the hook member 4 can be automatically removed by rotating the support shaft 43 upward by the buoyancy of the hook member 4.

したがって、潜水士による玉外し作業一切無くして、作業性を飛躍的に向上できる。また、遠隔操作によりフック部材４の閉鎖状態を解除できるため、フック支持体２にはクレーンワイヤーＭＷ（主巻）のみを連結すれば良く、吊り具１を引き揚げる際に補巻などが絡むことを防止して、安全な作業に寄与できる。 Therefore, the workability can be dramatically improved by eliminating the ball removal work by the diver. Further, since the closed state of the hook member 4 can be released by remote control, only the crane wire MW (main winding) needs to be connected to the hook support 2, and the auxiliary winding or the like is entangled when the hanger 1 is lifted. It can be prevented and contribute to safe work.

（変形例）
次に、第１の実施形態の変形例を図５から説明する。図５は変形例を図２に示すＩ−Ｉ矢視断面図と同様の箇所から矢視した矢視断面図である。また図５では、説明の関係上アクチュエータ部６、浮体８、フック支持体２の上部を省略している。また共通する部材には共通の符号を付している。 (Modification example)
Next, a modified example of the first embodiment will be described from FIG. FIG. 5 is a cross-sectional view taken along the arrow from a portion similar to the cross-sectional view taken along the line II shown in FIG. Further, in FIG. 5, the upper parts of the actuator portion 6, the floating body 8, and the hook support 2 are omitted for the sake of explanation. In addition, common members are designated by a common reference numeral.

以下、特に第１の実施形態との相違点のみ説明する。その他の点は第１の実施形態と同様である。変形例の吊り具１'の相違点は、閉鎖解除手段５００の構成にある。変形例の閉鎖解除手段５００は、ロック部材５１０がロック部５１０ａと操作部５１０ｂが支点Ｐを中心に異なる二つの方向へ放射状に延在し、平面視がくの字形状に形成されている。ロック部材５１０は、中心Ｐに枢支ピン５０が挿通されて、枢支ピン５０を中心にフック部材４に対して回動可能に構成されている。 Hereinafter, only the differences from the first embodiment will be described. Other points are the same as those of the first embodiment. The difference of the hanger 1'in the modified example lies in the configuration of the closing release means 500. In the closing release means 500 of the modified example, the lock member 510 has the lock portion 510a and the operation portion 510b extending radially in two different directions about the fulcrum P, and is formed in a dogleg shape in a plan view. The lock member 510 is configured such that the pivot pin 50 is inserted through the center P and is rotatable with respect to the hook member 4 about the pivot pin 50.

操作部５１０ｂの後方側（矢印Ｘ１側）の側面には、ロック部材５１０をロック側へ常時付勢するコイルバネで成る付勢手段５２０が設けられている。付勢手段５２０の他端部はフック部材４に当接されている。 On the side surface of the operation unit 510b on the rear side (arrow X1 side), a urging means 520 composed of a coil spring that constantly urges the lock member 510 toward the lock side is provided. The other end of the urging means 520 is in contact with the hook member 4.

ロック部５１０ａの先端部には爪部５１０ｃが形成されており、基部２２の係合突部２３０と係合してフック部材４の閉鎖位置を保持する構成である。 A claw portion 510c is formed at the tip of the lock portion 510a, and is configured to engage with the engaging protrusion 230 of the base portion 22 to hold the closed position of the hook member 4.

基部２２は、後方側にロック部５１０ａの回動を許容する切欠き部２２ａが設けられており、切欠き部２２ａ内に係合突部２３０が設けられている。切欠き部２２ａは、基部２２と外れ止め部３の一部に亘って設けられてよい。係合突部２３０は上方（矢印Ｙ１方向）に向かって突出している。 The base portion 22 is provided with a notch portion 22a that allows the lock portion 510a to rotate on the rear side, and an engaging protrusion 230 is provided in the notch portion 22a. The notch portion 22a may be provided over a part of the base portion 22 and the retaining portion 3. The engaging protrusion 230 projects upward (in the direction of arrow Y1).

変形例の吊り装置１００Ａ'においても、動作は第１の実施形態と略同様である。 Even in the suspension device 100A'of the modified example, the operation is substantially the same as that of the first embodiment.

作業者が遠隔操作手段７の発信部７２によりアクチュエータ部６のロッド部６１を伸張動作させる駆動信号を音波（又は超音波）で発信させると、図５（Ｂ）に示すように、ロッド部６１は直下位置に配置されたロック部材５１０の操作部５１０ｂを押し下げて、枢支ピン５０を中心に閉鎖解除方向（矢印Ｋ４方向）へ回動させる。するとロック部材５１０のロック部５１０ａは、係合突部２３０から離脱して、フック部材４の外れ止め部３による閉鎖状態が解除される。変形例においても第１の実施形態と同様の効果を奏する。 When the operator uses the transmitting unit 72 of the remote control means 7 to transmit a drive signal for extending the rod portion 61 of the actuator unit 6 by sound waves (or ultrasonic waves), the rod unit 61 is as shown in FIG. 5 (B). Pushes down the operation unit 510b of the lock member 510 arranged at the position directly below, and rotates the operation unit 510b around the pivot pin 50 in the closing release direction (arrow K4 direction). Then, the lock portion 510a of the lock member 510 is disengaged from the engaging protrusion 230, and the closed state by the retaining portion 3 of the hook member 4 is released. In the modified example, the same effect as that of the first embodiment is obtained.

［第２の実施形態］
次に、本発明の第２の実施形態に係る吊り装置１００Ｂを、図６、図７に基づいて説明する。第２の実施形態は、第１の実施形態と略同様の技術的思想に基づいており、以下に、第１の実施形態との相違点を中心に説明する。共通する部材には同じ符号を付し、説明は省略する。図６は、第２の実施形態に係る吊り装置１００Ｂの全体構成を説明する図である。図７は、図６に示す吊り具１０の動作を説明する図である。（Ａ）は外れ止め部３００による閉鎖状態が解除された状態を示す正面図である。（Ｂ）はフック部材４００が浮体８により上方に回動移動した状態を示す正面図である。
本実施形態の吊り装置１００Ｂは、吊り具１０と、浮体８と、遠隔操作手段７を有している。浮体８と遠隔操作手段７は第１の実施形態と同じであり説明は省略する。 [Second Embodiment]
Next, the suspension device 100B according to the second embodiment of the present invention will be described with reference to FIGS. 6 and 7. The second embodiment is based on a technical idea substantially the same as that of the first embodiment, and the differences from the first embodiment will be mainly described below. The common members are designated by the same reference numerals, and the description thereof will be omitted. FIG. 6 is a diagram illustrating the overall configuration of the suspension device 100B according to the second embodiment. FIG. 7 is a diagram illustrating the operation of the hanger 10 shown in FIG. (A) is a front view showing a state in which the closed state by the retaining portion 300 is released. (B) is a front view showing a state in which the hook member 400 is rotationally moved upward by the floating body 8.
The suspension device 100B of the present embodiment includes a suspension tool 10, a floating body 8, and a remote control means 7. The floating body 8 and the remote control means 7 are the same as those in the first embodiment, and the description thereof will be omitted.

吊り具１０は、フック支持体２００と、外れ止め部３００、フック部材４００と、アクチュエータ部６を有している。アクチュエータ部６は、第１の実施形態と同じであり、共通事項の説明は省略する。 The hanger 10 has a hook support 200, a retaining portion 300, a hook member 400, and an actuator portion 6. The actuator unit 6 is the same as that of the first embodiment, and the description of common matters will be omitted.

即ち、本実施形態の吊り具１０は、第１の実施形態の吊り具１を構成する閉鎖解除手段５が省略された構成である。 That is, the hanger 10 of the present embodiment has a configuration in which the closing release means 5 constituting the hanger 1 of the first embodiment is omitted.

フック支持体２００は、クレーンワイヤーＭＷ（主巻又は補巻き）と連結される環状部２１０と、環状部２１０と連続する基部２２０を有している。フック支持体２００の基部２２０の矢印Ｙ２側には、フック部材４００が一体的に連続して連結されている。また、フック支持体２００の基部２２０の矢印Ｙ２側の前方側に外れ止め部３００が回動可能に連結されている。 The hook support 200 has an annular portion 210 connected to the crane wire MW (main winding or auxiliary winding) and a base 220 continuous with the annular portion 210. A hook member 400 is integrally and continuously connected to the arrow Y2 side of the base 220 of the hook support 200. Further, the retaining portion 300 is rotatably connected to the front side of the base 220 of the hook support 200 on the arrow Y2 side.

フック部材４００は、アーム部４１０と支持部４２０とが略釣り針形状に一体形成され、アーム部４１０と支持部４２０とは略同一平面内に配置されている。アーム部４１０と支持部４２０は中実状に形成され、第１の実施形態のフック部材４のような左右一対のブラケット部４１ａは形成されていない。支持部４２０は正面視が半円弧形状に形成され、玉掛けワイヤーＴＷを安定して受け止めることができるように構成されている。 In the hook member 400, the arm portion 410 and the support portion 420 are integrally formed in a substantially fishing hook shape, and the arm portion 410 and the support portion 420 are arranged in substantially the same plane. The arm portion 410 and the support portion 420 are formed in a solid state, and the pair of left and right bracket portions 41a such as the hook member 4 of the first embodiment are not formed. The support portion 420 is formed in a semicircular arc shape when viewed from the front, and is configured to be able to stably receive the sling wire TW.

支持部４２０の先端部は略円柱状に形成され、上端部には切欠き形状の止め部４２０ａが形成されている。この止め部４２０ａに後述の外れ止め部３００の先端部の上面が当接されると、フック部材４００の開口部４０ａが閉鎖される。 The tip of the support portion 420 is formed in a substantially columnar shape, and a notch-shaped stop portion 420a is formed at the upper end. When the upper surface of the tip of the retaining portion 300, which will be described later, comes into contact with the stopper 420a, the opening 40a of the hook member 400 is closed.

外れ止め部３は、正面に視て上方に湾曲する湾曲部が形成されている。勿論、上方に向かって屈曲する屈曲部を有していてよい。外れ止め部３の上半部側の基端は、フック支持体２００の基部２２０に枢支ピン３１０を介して回動自在に連結されている。 The retaining portion 3 is formed with a curved portion that curves upward when viewed from the front. Of course, it may have a bent portion that bends upward. The base end on the upper half side of the retaining portion 3 is rotatably connected to the base 220 of the hook support 200 via a pivot pin 310.

枢支ピン３１０には捩りバネからなる付勢手段３２０が外装され、付勢手段３２０の一端部は外れ止め部３００に掛け止めされ、他端部はフック部材４又は基部２２０に掛け止められている。 A urging means 320 made of a torsion spring is externally attached to the pivot pin 310, one end of the urging means 320 is hooked to the retaining portion 300, and the other end is hooked to the hook member 4 or the base 220. There is.

外れ止め部３００は、付勢手段３２０により、先端部がフック部材４の支持部４２０の止め部４２０ａに掛け止められるように、図６に矢印Ｋ５（ロック側）で示す方向へ常時付勢されている。したがって本実施形態の外れ止め部３００は、矢印Ｋ６方向に回動されることで、フック部材４００の閉鎖状態が解除される構成である。 The retaining portion 300 is constantly urged by the urging means 320 in the direction indicated by the arrow K5 (lock side) in FIG. 6 so that the tip portion is hooked on the stopper portion 420a of the support portion 420 of the hook member 4. ing. Therefore, the retaining portion 300 of the present embodiment is configured to release the closed state of the hook member 400 by being rotated in the direction of the arrow K6.

本実施形態の外れ止め部３００の先端部には、アクチュエータ部６のロッド部６１の先端が連結されている。 The tip of the rod portion 61 of the actuator portion 6 is connected to the tip of the retaining portion 300 of the present embodiment.

なお、本実施形態のアクチュエータ部６は、第１の実施形態のアクチュエータ部６と同様であるが、取付位置が相違している。 The actuator unit 6 of the present embodiment is the same as the actuator unit 6 of the first embodiment, but the mounting position is different.

本実施形態のアクチュエータ部６は、フック部材４００のアーム部４１０の外周位置に取付金具（図示省略）などで取付けられており、ロッド部６１が吊り具１０の前方に向かって伸張する様態となるように配置される。したがって、フック部材４００の閉鎖状態において、ロッド部６１は、伸張した状態で外れ止め部３００の先端部と連結される。 The actuator portion 6 of the present embodiment is attached to the outer peripheral position of the arm portion 410 of the hook member 400 by a mounting bracket (not shown) or the like, and the rod portion 61 extends toward the front of the hanger 10. Arranged like this. Therefore, in the closed state of the hook member 400, the rod portion 61 is connected to the tip end portion of the retaining portion 300 in the extended state.

外れ止め部３００を矢印Ｋ６方向に回動させて、フック部材４００の閉鎖状態を解除するには、ロッド部６１を収縮動作させる必要がある。上記の点が第１の実施形態と相違する構成である。 In order to release the closed state of the hook member 400 by rotating the retaining portion 300 in the direction of arrow K6, it is necessary to contract the rod portion 61. The above point is different from the first embodiment.

＜動作＞
次に、図６、図７を参照しながら本実施形態の吊り装置１００Ｂ、特に吊り具１０の動作を簡潔に説明する。図６に示す吊り具１０は、フック部材４００が外れ止め部３００により開口部４０ａが閉鎖されている状態を示している。 <Operation>
Next, the operation of the suspension device 100B of the present embodiment, particularly the suspension tool 10, will be briefly described with reference to FIGS. 6 and 7. The hanger 10 shown in FIG. 6 shows a state in which the hook member 400 has the opening 40a closed by the retaining portion 300.

図６において吊り具１０は、玉掛けワイヤーＴＷにより被牽吊体Ｊを水中へ吊り下げている状態である。被牽吊体Ｊが水底に着底すると、潜水士は携帯している水中電話などで船上にいる作業者にフック部材４００の閉鎖状態を解除するよう指示する。すると作業者は、遠隔操作手段７の操作部７１を操作して、発信部７２によりアクチュエータ部６のロッド部６１を収縮動作させる駆動信号を音波（又は超音波）で発信させる。 In FIG. 6, the suspending tool 10 is in a state in which the suspended body J is suspended in water by a sling wire TW. When the suspended body J has landed on the bottom of the water, the diver instructs the operator on the ship to release the closed state of the hook member 400 by using a portable underwater telephone or the like. Then, the operator operates the operation unit 71 of the remote control means 7, and causes the transmission unit 72 to transmit a drive signal for contracting the rod portion 61 of the actuator unit 6 by sound waves (or ultrasonic waves).

アクチュエータ部６の受信部が駆動信号を受け取ると、駆動部はロッド部６１を収縮動作させる。すると、図７（Ａ）に示すようにロッド部６１は、外れ止め部３００を枢支ピン３１０を中心にロック解除方向（矢印Ｋ６方向）に回動させて、フック部材４００の外れ止め部３００による閉鎖状態を解除する。 When the receiving unit of the actuator unit 6 receives the drive signal, the drive unit contracts the rod unit 61. Then, as shown in FIG. 7A, the rod portion 61 rotates the retaining portion 300 around the pivot pin 310 in the unlocking direction (arrow K6 direction), and the retaining portion 300 of the hook member 400. Release the closed state by.

次に、閉鎖状態が解除されたフック部材４００は、図７（Ｂ）に示すように浮体８の浮力によりフック支持体２００と共に上方（矢印Ｋ７方向）へ回動して、玉掛けワイヤーＴＷを自動で取外すことができる。 Next, as shown in FIG. 7B, the hook member 400 whose closed state is released rotates upward (in the direction of arrow K7) together with the hook support 200 by the buoyancy of the floating body 8 to automatically perform the sling wire TW. It can be removed with.

したがって、潜水士による玉外し作業一切無くして、作業性を飛躍的に向上できる。また、第２の本実施形態においても第１の実施形態で記載したと同様の効果を奏することができる。 Therefore, the workability can be dramatically improved by eliminating the ball removal work by the diver. Further, also in the second embodiment, the same effect as described in the first embodiment can be obtained.

以上、本発明の好ましい実施形態について詳述したが、本発明は上記した特定の実施形態に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲内において、種々の変形・変更が可能なものである。 Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-mentioned specific embodiments, and various aspects are within the scope of the gist of the present invention described in the claims.
