<P>PROBLEM TO BE SOLVED: To provide a floating body connecting structure using a universal joint not transmitting a moment even to swings as well in the directions up and down and to the left and right as in the rolling direction, ensuring a wide degree of freedom for displacement, and capable of maintaining the durability for a long period of time. <P>SOLUTION: The connecting structure for mooring a floating body floating on a sea to a quay wall or connecting floating bodies together using the universal joint is configured so that the base end of one of the yokes of the universal joint is attached fast to the floating body or the quay wall and a rotating shaft extending in the connecting direction is installed protrusively behind the base end of the other yoke and mounted on the outer surface of the floating body or the quay wall rotatably through a flange, whereby the moment due to swinging of the floating body round the protruded rotating shaft is precluded from being transmitted to the member to be connected owing to rotation of the yokes. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、海上に浮揚する浮体を岸壁へ係留又は浮体同士を連結する浮体の連結構造に関する。   The present invention relates to a floating body connection structure for mooring a floating body floating on the sea to a quay or connecting floating bodies together.

従来、浮体の連結構造は特許文献1に開示されている。この技術は、浮体の対向間に設けられる連鎖継手としてボールジョイントを用いたものである。ボールジョイントは回動の軸方向性がないから、海域での波浪による浮体の揺動に対して柔軟に応答できる効果を有している。   Conventionally, a connection structure of floating bodies is disclosed in Patent Document 1. This technique uses a ball joint as a chain joint provided between opposing floating bodies. Since the ball joint has no axial direction of rotation, it has the effect of flexibly responding to the swinging of the floating body due to waves in the sea area.

ところで、浮体は質量が大きいため、前記ボールジョイントによる連結を行う場合に用いる中心部の球体も荷重に耐えうるべく必然的に大型化する。大型の球体は製造が難しく高精度が求められて高コストであり、この球体の表面に沿って摺動させる摺動体の取り付けも困難であった。また、円滑な回動のために定期的に給油する必要があり、海洋を汚染する問題もあった。   By the way, since the mass of the floating body is large, the sphere at the center used when the connection by the ball joint is performed is inevitably enlarged to withstand the load. Large spheres are difficult to manufacture and require high accuracy and high cost, and it is also difficult to attach a sliding body that slides along the surface of the sphere. In addition, there is a problem of polluting the ocean because it is necessary to periodically supply oil for smooth rotation.

これに対し、ユニバーサルジョイント(自在軸継手)を用いた浮体の連結技術が特許文献2〜4に開示されている。ユニバーサルジョイントは構成部品が全て旋盤等の加工機で容易且つ精度良く製作でき、組み立てや取り付けも容易で低コストにて実施でき、また給油の必要がないから海洋を汚染することがないというものである。   On the other hand, Patent Documents 2 to 4 disclose floating body connection techniques using universal joints (universal shaft joints). Universal joints can be manufactured easily and accurately with a lathe or other processing machine, are easy to assemble and install, can be implemented at low cost, and do not pollute the ocean because there is no need for refueling. is there.

しかしながら、これらの技術はユニバーサルジョイントのヨークの基端部が浮体や岸壁に固着されるものであるから、上下左右方向の揺動に対しては応答するが、ロール方向の揺動に対してはモーメントが連結先へ伝達してしまい、度重なる波浪により固着部分に負荷が作用して耐久性が低下する問題があった。
特開2003−191888号公報 実公平6−10219号公報 実公平6−34235号公報 特許第2923174号公報
However, these technologies respond to swinging in the vertical and horizontal directions because the base end of the universal joint yoke is fixed to the floating body and quay, but not to swinging in the roll direction. The moment is transmitted to the connection destination, and there is a problem that the durability is lowered due to the load acting on the fixed portion due to repeated waves.

にある。
The configuration of the present invention that solves this problem is as follows.
1) In a connection structure in which a floating body levitated on the sea is moored to a quay with a universal joint or the floating bodies are connected to each other, the base end of one yoke of the universal joint is fixed to the floating body or the quay and the base end of the other yoke A rotating shaft extending backward in the connecting direction is projected, and the rotating shaft is rotatably mounted on the outer surface of the floating body or quay with a mounting flange, and the moment caused by the swinging of the floating body around the projected rotating shaft is caused by the rotation of the yoke. Floating body connection structure characterized in that it is not transmitted to the connection destination 2) In the connection structure where floating bodies levitating on the sea are moored to the quay with a universal joint or floating bodies are connected to each other, the base end of one yoke of the universal joint The part is fixed to the floating body or the quay, and a rotating shaft extending in the connecting direction is provided behind the base end of the other yoke, and the rotating shaft is attached to the floating body or the quay. Floating body connection structure 3 characterized in that the moment caused by the swinging of the floating body around the projecting rotating shaft is not transmitted to the connection destination by the rotation of the yoke. ) A cross pin that supports the yokes of the universal joints is inserted into a hollow body with shaft holes in the vertical and horizontal directions so that the pins can rotate independently around the pin, and a sphere is placed in the center of the body. The structure according to 1) or 2), wherein the joint is configured such that the shaft end face of each pin inserted into the same spherical body is in contact with the shaft, and the yoke is pivotally supported by each protruding pin. Floating body connection structure 4) Cross pins that support the yokes of the universal joints are independent of each other, with a hollow body with shaft holes in the vertical and horizontal directions and pins with flanges on the shaft heads. Floating body connection structure according to 1) or 2), wherein a joint is formed by axially supporting the yokes with the flanges of the protruding pins and constituting a joint 5) The body of the cross pin Floating body connection structure described in 3) or 4) above in which an oil-free bearing or a noise-free bearing is interposed between the shaft hole and the pin 6) The universal joint has a bridge member disposed between the opposing yokes, and the bridge The floating body connection structure according to any one of 1) to 5), wherein both end portions of the member are pivotally supported with the tip portions of the respective yokes so as to be bent at two positions.

本発明によれば、浮体が波浪によりロール方向へ揺動した際、ユニバーサルジョイントの可動側のヨークが取り付け部分で回転軸周りに回転して連結先へのモーメントの伝達が遮断され、ジョイントの取り付け部分に負荷が作用することなく耐久性が長期に渡って維持される。   According to the present invention, when the floating body swings in the roll direction due to waves, the movable side yoke of the universal joint rotates around the rotation axis at the mounting portion, and the transmission of the moment to the connection destination is interrupted, and the joint mounting Durability is maintained for a long time without load acting on the part.

本発明のユニバーサルジョイントの取り付けとしては、ヨークの回転軸を浮体又は岸壁の外面に取付フランジで回転可能に取り付ける方法や、ヨークの回転軸を浮体又は岸壁に形成した軸穴に軸挿して回転可能に取り付ける方法があり、任意に選ばれる。岸壁への係留は係留アームを介して成され、係留アームの端部に同様のユニバーサルジョイントを取り付けて浮体と岸壁とを2点又は3点支持で連結する。   The universal joint of the present invention can be attached by a method in which the rotary shaft of the yoke is rotatably attached to the outer surface of the floating body or quay by a mounting flange, or the rotary shaft of the yoke can be rotated by being inserted into a shaft hole formed in the floating body or the quay. There is a method of attaching to, and is arbitrarily selected. Mooring to the quay is made through a mooring arm, and a similar universal joint is attached to the end of the mooring arm to connect the floating body and the quay with two or three points.

ユニバーサルジョイントのヨーク同士を軸支するクロスピンは、上下左右方向に軸穴を形成した中空のボディにピンをそれぞれ独立してピン周りに回転可能に軸挿した構造とすると、大型大質量の浮体からの荷重を独立したピンで受け流し、クロスピンを破損させることなく大荷重に十分に耐え得る連結構造とすることができる。   A cross pin that supports the yokes of a universal joint is a hollow body with shaft holes in the top, bottom, left, and right directions. Thus, a connection structure that can sufficiently withstand a large load without damaging the cross pin can be obtained.

また、このクロスピンは4本のクロスピンを中心の球体に押し当てるように差し込み、クロスピンのエンドキャップで押えるだけの簡易な構造でクロスピンの保持ができる。この場合のクロスピンは一様な径のピンで良いため、製作工数の低減が図られ、量産品の安価な球体を用いる場合にはそのメリットはより大きくなる。以下、本発明の各実施例を図面に基づいて具体的に説明する。   Further, the cross pin can be held with a simple structure in which the four cross pins are inserted so as to press against the center sphere, and can be pressed by the end cap of the cross pin. Since the cross pin in this case may be a pin having a uniform diameter, the number of manufacturing steps can be reduced, and the merit can be further increased when an inexpensive sphere of mass production is used. Embodiments of the present invention will be specifically described below with reference to the drawings.

図1〜5に示す実施例1は、ユニバーサルジョイントのヨークの回転軸を浮体の外面に取付フランジで回転可能に取り付けた例である。図1は実施例1のユニバーサルジョイントの一部切欠斜視図、図2は実施例2のユニバーサルジョイントの分解斜視図、図3は実施例1の浮体の係留及び浮体間の連結を示す説明図、図4は実施例1のユニバーサルジョイントの外観図、図5は実施例1のヨークの取り付けを示す説明図である。   1 to 5 is an example in which a rotation shaft of a universal joint yoke is rotatably attached to an outer surface of a floating body with a mounting flange. FIG. 1 is a partially cutaway perspective view of the universal joint of the first embodiment, FIG. 2 is an exploded perspective view of the universal joint of the second embodiment, and FIG. 3 is an explanatory view showing the mooring of the floating body and the connection between the floating bodies of the first embodiment. FIG. 4 is an external view of the universal joint according to the first embodiment, and FIG. 5 is an explanatory view showing attachment of the yoke according to the first embodiment.

図中、1はユニバーサルジョイント、2は可動ヨーク、2aは回転軸、2bはピン穴、3は固定ヨーク、3aはピン穴、4はクロスピン、4aはクロスピンボディ、4bは軸穴、4cはピン、4dは球体、4eはエンドキャップ、5は取付フランジ、5aは取付ボルト、6はスラスト軸受、7はラジアル軸受、8は軸止フランジ、Aは係留アーム、Fは浮体、Gは岸壁、Wは海である。   In the figure, 1 is a universal joint, 2 is a movable yoke, 2a is a rotating shaft, 2b is a pin hole, 3 is a fixed yoke, 3a is a pin hole, 4 is a cross pin, 4a is a cross pin body, 4b is a shaft hole, and 4c is a pin 4d is a sphere, 4e is an end cap, 5 is a mounting flange, 5a is a mounting bolt, 6 is a thrust bearing, 7 is a radial bearing, 8 is a shaft flange, A is a mooring arm, F is a floating body, G is a quay, W Is the sea.

実施例1のユニバーサルジョイント1は、図1,2に示すように基端部の後方に連結方向へ伸びる回転軸2aを備えた可動ヨーク2と固定ヨーク3をクロスピンボディ4aを介して対向配置し、独立したピン4cを可動ヨーク2のピン穴2bと固定ヨーク3のピン穴3aを通じてクロスピンボディ4aの穴4bに球体4dとともにそれぞれ軸挿し、エンドキャップ4eでピン穴2b,3aを封止して構成している。   As shown in FIGS. 1 and 2, the universal joint 1 according to the first embodiment has a movable yoke 2 having a rotating shaft 2a extending in the connecting direction behind the base end portion and a fixed yoke 3 disposed opposite to each other via a cross pin body 4a. The independent pin 4c is inserted into the hole 4b of the cross pin body 4a together with the sphere 4d through the pin hole 2b of the movable yoke 2 and the pin hole 3a of the fixed yoke 3, and the pin holes 2b and 3a are sealed with the end cap 4e. It is composed.

図3,4に示すように、上記ユニバーサルジョイント1の固定ヨーク3を一方の浮体Fの外面に取付プレート9を介して固着し、反対側の可動ヨーク2の回転軸2aにスラスト軸受6及びラジアル軸受7を嵌挿するとともに取付フランジ5を介して軸止フランジ8を軸着し、取付フランジ5を他方の浮体Fの外面に取付プレート9を介して固着する。岸壁Gに隣接する浮体Fは、岸壁G側に上記ユニバーサルジョイント1を取り付けた係留アームAを介装して係留する。   As shown in FIGS. 3 and 4, the fixed yoke 3 of the universal joint 1 is fixed to the outer surface of one floating body F via a mounting plate 9, and a thrust bearing 6 and a radial are mounted on the rotating shaft 2 a of the movable yoke 2 on the opposite side. The bearing 7 is fitted and the shaft-fixing flange 8 is axially attached via the attachment flange 5, and the attachment flange 5 is fixed to the outer surface of the other floating body F via the attachment plate 9. The floating body F adjacent to the quay G is moored via a mooring arm A to which the universal joint 1 is attached on the quay G side.

なお、スラスト軸受6及びラジアル軸受7は一般的に金属製を用いるが、樹脂系摺動材を採用することもある。樹脂系摺動材は金属製の軸受と比較して剛性が低いから浮体Fの揺動による衝撃力を効果的に緩和できる。また、バネ等の付勢手段を採用することもできる。   In addition, although the thrust bearing 6 and the radial bearing 7 are generally made of metal, a resin-based sliding material may be used. Since the resin-based sliding material has low rigidity as compared with a metal bearing, the impact force caused by the swinging of the floating body F can be effectively reduced. Further, biasing means such as a spring can be employed.

図4(a)は浮体F同士を連結するユニバーサルジョイントの外観、図4(b)は浮体Fと係留アームAを連結するユニバーサルジョイントの外観を示している。また、図5にはスラスト軸受の配置の各例を示している。図5(a)は、回転軸2aの後端に軸着した軸止フランジ8を前後から挟持するようにスラスト軸受6を配置している例である。図5(b)は、可動ヨーク2の後面と軸止フランジ8の前面に取付フランジ5を前後から挟持するようにスラスト軸受6を配置している例である。   4A shows the appearance of a universal joint that connects the floating bodies F together, and FIG. 4B shows the appearance of the universal joint that connects the floating body F and the mooring arm A. FIG. FIG. 5 shows examples of the arrangement of thrust bearings. FIG. 5A shows an example in which the thrust bearing 6 is disposed so as to sandwich the shaft-stop flange 8 pivotally attached to the rear end of the rotary shaft 2a. FIG. 5B is an example in which the thrust bearing 6 is arranged so that the mounting flange 5 is sandwiched from the front and the rear on the rear surface of the movable yoke 2 and the front surface of the shaft flange 8.

実施例1はこのように構成したから、浮体Fが波浪によりロール方向へ揺動した際、ユニバーサルジョイント1の可動ヨーク2が取り付け部分で回転軸周りに回転して隣接する浮体F又は係留アームA又は岸壁Gへのモーメントの伝達が遮断され、ジョイントの取り付け部分に負荷が作用することなく耐久性が長期に渡って維持された。また、クロスピン4のピン4cを独立して回転可能にしたから、大型大質量の浮体Fからの荷重を独立したピン4cで受け流し、クロスピン4の破損を防止して大荷重に十分耐え得る連結構造とすることができた。   Since the first embodiment is configured as described above, when the floating body F swings in the roll direction due to the waves, the movable yoke 2 of the universal joint 1 rotates around the rotation axis at the mounting portion and is adjacent to the floating body F or the mooring arm A. Alternatively, the transmission of the moment to the quay G was interrupted, and the durability was maintained for a long time without any load acting on the joint mounting portion. In addition, since the pin 4c of the cross pin 4 can be rotated independently, the connection structure that can receive the load from the large and large mass floating body F by the independent pin 4c and prevent the cross pin 4 from being damaged and sufficiently withstand the heavy load. And was able to.

図6に示す実施例2は、ユニバーサルジョイントのヨークの回転軸を浮体又は岸壁に形成した軸穴に軸挿して回転可能に取り付けた例である。図6は実施例2のヨークの取り付けを示す説明図である。実施例2のユニバーサルジョイント1は、構造は実施例1と同様であるが、可動ヨーク2の回転軸2aを浮体Fに形成した軸穴10へ軸挿して回転可能に取り付けている。   Example 2 shown in FIG. 6 is an example in which a rotation shaft of a universal joint yoke is rotatably inserted by being inserted into a shaft hole formed in a floating body or a quay. FIG. 6 is an explanatory view showing attachment of the yoke according to the second embodiment. The universal joint 1 of the second embodiment has the same structure as that of the first embodiment, but is rotatably mounted by inserting the rotating shaft 2a of the movable yoke 2 into the shaft hole 10 formed in the floating body F.

図6(a)は、可動ヨーク2の後面と軸止フランジ8の前面に軸穴10の縮径部を前後から挟持するようにスラスト軸受6を配置している例である。図6(b)は、前方へ配設した軸止フランジ8の拡径部を前後から挟持するようにスラスト軸受6を配置している例である。このように、可動ヨーク2を浮体F内部に組み込むことで、実施例1と比較してスラスト軸受6を大荷重に耐えられる大型構造にすることが可能である。その他、符号、構成は実施例1と同じである。   FIG. 6A is an example in which the thrust bearing 6 is disposed so that the reduced diameter portion of the shaft hole 10 is sandwiched from the front and the rear on the rear surface of the movable yoke 2 and the front surface of the shaft locking flange 8. FIG. 6B is an example in which the thrust bearing 6 is arranged so as to sandwich the enlarged diameter portion of the shaft flange 8 disposed forward from the front and rear. Thus, by incorporating the movable yoke 2 into the floating body F, it is possible to make the thrust bearing 6 have a large structure capable of withstanding a heavy load as compared with the first embodiment. Other reference numerals and configurations are the same as those in the first embodiment.

図7に示す実施例3は球体を省略したクロスピンの例である。図7は実施例3のクロスピンの断面図である。図中、4fはフランジ、4gは摺動材、4hは取付ボルトである。   Example 3 shown in FIG. 7 is an example of a cross pin in which a sphere is omitted. FIG. 7 is a cross-sectional view of the cross pin of the third embodiment. In the figure, 4f is a flange, 4g is a sliding member, and 4h is a mounting bolt.

図7に示すクロスピン4は、各軸穴4b内に無給油軸受又は無騒音軸受からなる摺動材4gを介して可動ヨーク2及び固定ヨーク3を各ピン穴2b,3aと各軸穴4bとが連通するように配置し、軸頭にフランジ4fを備えたピン4cをそれぞれ軸挿し、各ピン4cのフランジ4fと可動ヨーク2及び固定ヨーク3とを取付ボルト4hで固定している。   In the cross pin 4 shown in FIG. 7, the movable yoke 2 and the fixed yoke 3 are respectively connected to the pin holes 2b and 3a and the shaft holes 4b via the sliding material 4g made of an oil-free bearing or a noiseless bearing in each shaft hole 4b. Are arranged so as to communicate with each other, and pins 4c having flanges 4f at the shaft heads are respectively inserted into the shafts, and the flanges 4f of the respective pins 4c, the movable yoke 2 and the fixed yoke 3 are fixed by mounting bolts 4h.

従って、実施例3ではピン4cにフランジ4fを設ける必要があるが、クロスピンボディ4aの中央部に配設していた球体4dを省略でき、構造は簡略化される。その他、符号、構成は実施例1と同じである。   Therefore, in Embodiment 3, it is necessary to provide the pin 4c with the flange 4f. However, the spherical body 4d disposed at the center of the cross pin body 4a can be omitted, and the structure is simplified. Other reference numerals and configurations are the same as those in the first embodiment.

図8に示す実施例4はダブル構造のユニバーサルジョイントを用いた例である。図8は実施例4のヨークの取り付けを示す説明図、図8(a)は縦断面図、図8(b)は横断面図である。図中、11はブリッジ部材、11aは軸穴である。   Example 4 shown in FIG. 8 is an example using a universal joint having a double structure. 8A and 8B are explanatory views showing attachment of the yoke according to the fourth embodiment, FIG. 8A is a longitudinal sectional view, and FIG. 8B is a transverse sectional view. In the figure, 11 is a bridge member, and 11a is a shaft hole.

図8に示すユニバーサルジョイント1は、両端の二股先端部に軸穴11aを有したブリッジ部材11を可動ヨーク2と固定ヨーク3の間に配置し、前記実施例1に示すクロスピン4でそれぞれ軸支して2箇所で屈曲できるダブル構造のジョイントに構成している。   In the universal joint 1 shown in FIG. 8, a bridge member 11 having a shaft hole 11a at both ends of a bifurcated tip is disposed between a movable yoke 2 and a fixed yoke 3, and each is supported by a cross pin 4 shown in the first embodiment. Thus, a double structure joint that can be bent at two locations is formed.

従って、1箇所で屈曲するユニバーサルジョイント1と比較してより大きい波浪等に対しても柔軟に応答し、ジョイントの取り付け部分に作用する負荷を極力低減して耐久性をより長期に渡って維持することができる。その他、符号、構成は実施例1と同じである。   Therefore, it responds flexibly to larger waves compared to the universal joint 1 bent at one place, and the load acting on the joint mounting portion is reduced as much as possible to maintain the durability for a longer period. be able to. Other reference numerals and configurations are the same as those in the first embodiment.

本発明の浮体の連結構造は、浮消波堤や浮桟橋,バージ,いけす,人工島などに広く応用できる。   The connection structure of floating bodies of the present invention can be widely applied to floating breakwaters, floating piers, barges, sails, artificial islands, and the like.
