Description

本発明は吊り上げ機械に関するものであり、特に海上石油プラットフォームのブロックをドッキングする場合の吊り上げ・据付用の複数吊りポイントクレーン、及びその他の同類クレーンにおける複数巻き上げシステムの空間干渉防止配置に関するものである。   The present invention relates to a lifting machine, and more particularly to a space interference prevention arrangement for a multiple lifting system for lifting and installation of multiple lifting point cranes when docking offshore oil platform blocks and other similar cranes.

海上石油プラットフォームのブロックドッキングは、複数吊りポイントのクレーンに対し、特大吊り上げ荷重（共同吊り上げ最大負荷は２万トン）と特大吊り上げ高度（最大１０３ｍ）及び特大主桁スパン（１２５ｍ）が要求されている。特大吊り上げ荷重のクレーンは吊り上げ高度を高め、高グレード（Ｃ５０級）コンクリート台座によりもたらされる高い建築コストを低減するために、主桁は下部のフランジプレートが水平で、上部のカバープレートの中央部が高く、両側部が低い構造を採用し、且つ桁の幅が狭くなくてはならない。また、吊り上げ荷重が過大であるため、複数の巻き上げシステム（各主桁の各端に２基また２基以上の巻き上げシステムが設けられる）を用いて同時に吊り上げなければならない。   Block docking of offshore oil platform requires extra large lifting load (maximum joint lifting is 20,000 tons), extra large lifting height (up to 103m) and extra large main girder span (125m) for cranes with multiple suspension points. . Oversized lifting load cranes raise the lifting height and reduce the high construction cost provided by high grade (C50 grade) concrete pedestals, the main girder has the lower flange plate horizontal and the upper cover plate center The structure must be high and the sides are low, and the width of the girders must be narrow. Moreover, since the lifting load is excessive, it must be lifted simultaneously using a plurality of hoisting systems (two or more hoisting systems are provided at each end of each main girder).

しかし、従来のクレーンの吊り上げ機構及び巻き取りシステムの数が少なく、一般的に１〜２基であり、配置は交差せず、平面に配置するだけで実現できるが、石油プラットフォームで特大荷重の吊り上げができない。そのため、複数吊りポイントのクレーンを採用しなければならない。複数基の吊り上げ機構及びワイヤロープの巻き取りシステムを主桁の狭い幅の中に配置するのは、普通の配置方式では実現することができない。通常、複数の吊りポイントクレーンは特大荷重の吊り上げに用い、その主桁の高度が高く、一方主桁腹板間の幅寸法が小さいので、複数基の独立巻上げシステムの空間配置はワイヤロープの間またはワイヤロープと主桁の間に干渉が起こりやすい。そのため、複数吊りポイントクレーンの玉掛けワイヤロープの空間干渉防止配置の研究は最も切実な技術課題である。   However, the number of conventional crane lifting mechanisms and winding systems is small, generally one or two, and the arrangement is not crossed and can be realized simply by placing them on a flat surface. I can't. Therefore, a crane with multiple suspension points must be employed. Arrangement of a plurality of lifting mechanisms and a wire rope winding system within a narrow width of the main girder cannot be realized by an ordinary arrangement method. Usually, multiple suspension point cranes are used for lifting oversized loads, and the height of the main girder is high, while the width between the main girder bells is small, so the spatial arrangement of multiple independent hoisting systems is between wire ropes. Or interference is likely to occur between the wire rope and the main beam. Therefore, research on the arrangement for preventing spatial interference of the sling wire ropes of the multiple suspension point crane is the most urgent technical issue.

本発明は上記の課題を解決するために考案されたものである。   The present invention has been devised to solve the above problems.

複数基の巻き上げ機を主桁上部に取り付け、異なる巻上げ機台座の高さを採用することや主桁各端の複数基の巻き上げ機ドラムの中心とガイドプーリー中心の接続線を主桁中心線に対し１つの小偏角を形成させることにより、ワイヤロープを主桁上部空間に沿って交差配置を形成させた後、ガイドプーリーを通して***から主桁に入り定滑車・動滑車装置に巻き取る。本発明の技術手段は下記のとおりである。   Install multiple hoisting machines at the top of the main girder, adopt different hoisting machine pedestal heights, and connect the center of the multiple hoisting drums at each end of the main girder to the center of the guide pulley On the other hand, by forming one small declination, the wire rope is formed in an intersecting arrangement along the main girder upper space, and then enters the main girder from the small hole through the guide pulley and is wound around the fixed pulley / moving pulley device. The technical means of the present invention are as follows.

主桁、動滑車装置、定滑車装置、巻上げ機を含む一種の複数吊りポイントクレーンの玉掛けワイヤロープの空間干渉防止配置である。ガイドプーリーが前記主桁上部カバープレートの上部空間に設けられ、両端のカバープレートに巻上げ機固定用の台座が設けられている。前記のワイヤロープはガイドプーリーと巻上げ機の有効部分の間にワイヤロープ占用面積を形成し、当該面積はガイドプーリーを頂角とする二つの三角形△ＡＢＣと△Ａ’Ｂ’Ｃ’で表すことができる。その特徴は前記二つの三角形が分界線Ｉ−Ｉ’に沿って対称し、且つ向かい合って配置され、分界線Ｉ−Ｉ’と主桁中心線の間に小偏角θを形成する。前記主桁上部カバープレートの両端に２基または２基以上の巻き上げ機が設けられる。前記の各巻き上げ機台座の高さが異なり、且つ各ガイドプーリーの据付高さと位置も各巻き上げ機台座の高さに対応し異なっているため、形成されたワイヤロープの占用面は同一平面上にない。   This is a space interference prevention arrangement of a sling wire rope of a kind of multiple suspension point crane including a main girder, a moving pulley device, a fixed pulley device, and a hoisting machine. A guide pulley is provided in the upper space of the main girder upper cover plate, and pedestals for fixing the winder are provided on the cover plates at both ends. The wire rope forms an area occupied by the wire rope between the guide pulley and the effective portion of the hoist, and the area is represented by two triangles ΔABC and ΔA'B'C 'with the apex angle of the guide pulley. Can do. The feature is that the two triangles are symmetrically arranged along the boundary line I-I 'and are opposed to each other to form a small deviation angle θ between the boundary line I-I' and the main beam center line. Two or more hoisting machines are provided at both ends of the main girder upper cover plate. The height of each hoisting machine pedestal is different, and the installation height and position of each guide pulley are also different corresponding to the height of each hoisting machine pedestal, so the occupied surface of the formed wire rope is on the same plane Absent.

前記両端各基の巻き上げ機ドラム垂直中心線とガイドプーリー中心線との連続線も主桁中心線との間に一つの小偏角αが形成され、同じ端部にある各巻き上げ機と主桁で形成している偏角の方向は一致し、且つ主桁両端の巻き上げ機と主桁で形成している偏角は向い合っている。前記巻き上げ機のワイヤロープは主桁のカバープレートの上部空間に沿って一つの固定されたガイドプーリーを通し、前記主桁上部のカバープレートのシングルロープの出／入穴から主桁内の定滑車装置に入った後、動滑車装置に巻き取り、さらに動滑車と定滑車の間に繰り返して巻き取ってから、最後に主桁上の定滑車装置側面の固定端に固定する。   The winding machine drum vertical center line at each end and the continuous line of the guide pulley center line are also formed with a small declination angle α between the main beam center line, and each winding machine and main beam at the same end. The direction of the declination formed at the same is the same, and the declination formed by the hoisting machines at both ends of the main girder and the main girder are facing each other. The wire rope of the hoisting machine passes a fixed guide pulley along the upper space of the cover plate of the main girder, and the fixed pulley in the main girder from the exit / entry hole of the single rope of the cover plate of the upper portion of the main girder After entering the device, it is wound around the moving pulley device, and further repeatedly wound between the moving pulley and the fixed pulley, and finally fixed to the fixed end on the side of the fixed pulley device on the main girder.

また、Ｌ＞ａ／２の場合、前記小偏角θと前記小偏角αの範囲は０°＜θ＜９０°で、α≦ζである。その内、Ｌはドラムの長さ、ａは主桁上部カバープレートの幅、ｂは主桁上部カバープレートの長さ、ζは巻き上げ機のワイヤー送り偏角である。   When L> a / 2, the range of the small deviation angle θ and the small deviation angle α is 0 ° <θ <90 ° and α ≦ ζ. Among them, L is the length of the drum, a is the width of the main girder upper cover plate, b is the length of the main girder upper cover plate, and ζ is the wire feed deflection angle of the hoisting machine.

最適方案は下記のとおりである。分界線Ｉ−Ｉ′は前記両端各基の巻上げ機ドラム垂直中心線はガイドプーリー中心線の連続線と平行していて、且つ小偏角αイコール小偏角θであり、両端各基の巻上げ機がガイドプーリー（２）と対称して配置されている。前記の各巻上げ機から構成されている各巻上げシステム中の動滑車装置は連接棒で連結されている。主桁両端カバープレートの巻き上げ機台座は階段状に分布されていて、且つ各ガイドプーリーの据付高度が各巻上げ機台座の高度と対応している。   The optimal plan is as follows. The demarcation line II ′ is the winding machine drum vertical center line at each end of each group is parallel to the continuous line of the guide pulley center line and has a small deviation angle α equal to a small deviation angle θ. The machine is arranged symmetrically with the guide pulley (2). The moving pulley apparatus in each winding system composed of the above-described winding machines is connected by a connecting rod. The hoist bases of the main girder cover plates are distributed stepwise, and the installation height of each guide pulley corresponds to the height of each hoist base.

上記の技術方案を採用することにより、本発明の複数吊りポイントクレーンの玉掛けワイヤロープの空間干渉防止配置は、簡単な構成で実現することができた。複数基巻き上げシステムにより構成する吊り上げ機構のワイヤーロープシステム空間干渉防止配置方案は、高アスペクト比合成梁を採用した特大吊り上げ高度及び特大スパンの複数吊りポイントクレーンに適合し、当該クレーンで石油プラットフォーム等特大荷重を吊り上げる場合、下記のメリットを有する。
１．複数吊りポイントクレーンの吊り上げ機構の作動が安全になり、信頼性が高くなる。
２．装置の配置は簡単であり、製造、取付、メンテナンスも便利になる。
３．複数基の巻き上げシステムにより構成する吊り上げ機構の効率が高くなる。
４．自重が軽く、幅が狭い主桁に適用できるため、クレーン全体のコストを低減できる。 By adopting the above technical scheme, the space interference prevention arrangement of the sling wire rope of the multiple suspension point crane of the present invention could be realized with a simple configuration. The wire rope system of the lifting mechanism composed of multiple hoisting systems The spatial interference prevention arrangement plan is suitable for extra large lifting height and extra large span multiple lifting point cranes using high aspect ratio composite beams, and the crane is extra large for oil platforms etc. When lifting a load, it has the following advantages.
1. The operation of the lifting mechanism of the multiple suspension point crane becomes safe and the reliability becomes high.
2. The arrangement of the device is simple and the manufacture, installation and maintenance are convenient.
3. The efficiency of the lifting mechanism constituted by a plurality of winding systems is increased.
4). Since the weight of the crane is light and it can be applied to narrow main girders, the cost of the crane can be reduced.

図１から図４に示すように、複数吊りポイントクレーンの玉掛けワイヤロープ空間干渉防止配置は、石油プラットフォーム等特大荷重部材の吊り上げ用複数吊りポイントクレーンに応用されている。通常、当該クレーンは特大荷重の吊り上げに用いられ、その主桁の高さが高く、主桁腹板間の幅が小さく、一般的に複数基の巻き上げシステムにより構成される。 As shown in FIGS. 1 to 4, the sling wire rope space interference preventing arrangement of the multiple suspension point crane is applied to a multiple suspension point crane for lifting an extra large load member such as an oil platform. Usually, the crane is used for lifting an extra large load, and the height of the main girder is high, the width between the main girder belly plates is small, and it is generally constituted by a plurality of hoisting systems.

各巻き上げシステムは巻上げ機１、ガイドプーリー２、動滑車装置３、動滑車装置間の連接棒４、定滑車装置５、ワイヤロープ６、巻上げ機台座７等により構成され、一般的に各基の巻き上げシステムは４つの動滑車装置を有し、各動滑車装置の下に１つの吊りポイントが制御されている。   Each hoisting system includes a hoisting machine 1, a guide pulley 2, a moving pulley device 3, a connecting rod 4 between the moving pulley devices, a fixed pulley device 5, a wire rope 6, a hoisting machine base 7, and the like. The hoisting system has four moving pulley devices, and one suspension point is controlled under each moving pulley device.

巻上げ機１はモーターと連続されているカップリングから最終段階のブレーキまでの全基駆動装置であり、ドラム（ワイヤロープ固定金具）、減速器、ブレーキ、開放ギア、カップリング、浮動軸等の部品により構成している。その内、ワイヤロープ６はガイドプーリー２と巻上げ機１の有効部分の間にワイヤロープの占用面積を形成し、当該面積はガイドプーリー２を頂角とする二つの三角形△ＡＢＣと△Ａ’Ｂ’Ｃ’で表すことができる。   The hoisting machine 1 is an all-base drive device from the coupling that is continuous with the motor to the brake at the final stage, such as drum (wire rope fixing bracket), speed reducer, brake, release gear, coupling, floating shaft, etc. It is constituted by. Among them, the wire rope 6 forms an occupied area of the wire rope between the guide pulley 2 and the effective portion of the hoisting machine 1, and the area is two triangles ΔABC and ΔA′B with the guide pulley 2 as an apex angle. It can be represented by “C”.

図４に示すように、Ｌ＞ａ／２の場合（Ｌはドラムの長さ、ａは主桁上部カバープレートの幅、ｂは主桁上部カバープレートの長さ、ζは巻き上げ機のワイヤー送り偏角である）即ち二つの三角形の頂点ＡとＡ’がぶつかる場合、必ず従来の機械装置で解決できない干渉の問題が発生する。よって、本発明は二つの三角形を分界線Ｉ−Ｉ′に沿って対称させ、且つ向かい合って配置しており、分界線Ｉ−Ｉ′と主桁中心線の間に小偏角θが形成され、当該小偏角θの範囲は０°＜θ＜９０°である。   As shown in FIG. 4, when L> a / 2 (L is the length of the drum, a is the width of the main girder upper cover plate, b is the length of the main girder upper cover plate, ζ is the wire feed of the hoisting machine When the vertices A and A ′ of two triangles collide with each other, an interference problem that cannot be solved by a conventional mechanical device occurs. Therefore, in the present invention, the two triangles are symmetrically arranged along the demarcation line II ′ and opposite to each other, and a small deviation angle θ is formed between the demarcation line II ′ and the main beam center line. The range of the small deviation angle θ is 0 ° <θ <90 °.

巻き上げ機１を主桁１０のカバープレートの上に放置し、各主桁両端のカバープレートに２基または２基以上の巻き上げ機を配置する。各基の巻き上げ機のワイヤロープ６は主桁カバープレートの上部空間に沿って一つの固定されたガイドプーリー２を通して主桁上部カバープレートのシングルロープの出／入穴８から主桁内の定滑車装置５に入った後、動滑車装置３に巻き取り、動滑車と定滑車の間に繰り返して巻き取り、図４に示すように最終的に主桁内の定滑車装置側面にある固定端９に固定されている。   The hoisting machine 1 is left on the cover plate of the main girder 10, and two or more hoisting machines are arranged on the cover plates at both ends of each main girder. The wire rope 6 of each hoisting machine passes through a single fixed guide pulley 2 along the upper space of the main girder cover plate, through a single rope exit / entry hole 8 of the main girder cover plate, and a fixed pulley in the main girder. After entering the device 5, it is wound around the moving pulley device 3, repeatedly wound between the moving pulley and the fixed pulley, and finally the fixed end 9 on the side of the fixed pulley device in the main girder as shown in FIG. It is fixed to.

そのうち、主桁両端部上の各基巻上げ機は高さが異なっている巻き上げ機台座７を採用することにより、各巻上げ機ドラムのワイヤロープ６の送り高さを異なるようにし、且つ形成されたワイヤロープの占用面は同一平面上にない。主桁１０の両端部カバープレートの巻き上げ機台座７は階段状に分布されていて、且つ図３に示すように、各ガイドプーリー２の据付高さと各巻上げ機台座７の高さと対応している。他の両端部各基の巻き上げ機１のドラム垂直中心線とガイドプーリー２の中心線と主桁１０を連結する中心線との間にも１つの小偏角αが形成され、小偏角αの範囲はα≦ζであり、その内ζは巻き上げ機のロープ送り偏角で、且つζ≦２°である。   Among them, the base hoisting machines on both ends of the main girder are formed by adopting hoisting machine bases 7 having different heights so that the feeding heights of the wire ropes 6 of the hoisting machine drums are different. The occupied surface of the wire rope is not on the same plane. The winding machine bases 7 of the cover plates at both ends of the main girder 10 are distributed stepwise and correspond to the installation height of each guide pulley 2 and the height of each winding machine base 7 as shown in FIG. . One small deflection angle α is also formed between the drum vertical center line of the winding machine 1 at each of the other end portions, the center line of the guide pulley 2 and the center line connecting the main girder 10. Is in the range of α ≦ ζ, of which ζ is the rope feed deflection angle of the hoist and ζ ≦ 2 °.

また、分界線Ｉ−Ｉ′は前記の両端の各基巻上げ機１のドラム垂直中心線はガイドプーリー２中心線の連続線と平行していて、且つ小偏角αイコール小偏角θ、両端の各基巻上げ機はガイドプーリーと対称配置されていて、同一の端部にある各巻き上げ機１と主桁１０に形成している偏角の方向は一致している。このような配置はワイヤロープ６を空間的に交差配置させることができ、ワイヤロープ間及びワイヤロープと主桁間の干渉を防止できるだけではなく、ワイヤロープと巻上げ機ドラム及び滑車との偏角を標準に符合させる。また、各巻上げ機１からなる各巻上げシステム中の動滑車装置３は連接棒４で連結している。   Further, the demarcation line II ′ is the drum vertical center line of each of the base hoisting machines 1 at both ends is parallel to the continuous line of the guide pulley 2 center line, and the small deviation angle α is equal to the small deviation angle θ. Each of the basic hoisting machines is symmetrically arranged with the guide pulley, and the direction of the declination formed in each hoisting machine 1 and the main girder 10 at the same end is the same. Such an arrangement allows the wire ropes 6 to be spatially crossed to prevent interference between the wire ropes and between the wire ropes and the main girder, as well as to deviate the angle between the wire rope and the hoisting drum and pulley. Match the standard. Further, the moving pulley device 3 in each winding system composed of each winding machine 1 is connected by a connecting rod 4.

ここで主桁に６基の巻き上げシステムが設けられる構造を例として説明する。主桁１０に６基の巻き上げ機１が設置され、ワイヤロープのドラムと滑車上の偏角が標準規定を超えないことを保証するために、各端部に３基巻上げ機１が採用され、その内の主桁の長さｂは１３０メートル、上部カバープレートの幅ａは４メートルで、巻揚上げ機許容のワイヤロープ偏角はζ≦２°であり、前記の経験公式によりθの値が１．０４度であると計算できる。この場合、両端部の各基巻き上げ機１のドラム垂直中心線とガイドプーリー２の中心線連続線は主桁１０の中心線との間に形成された１つの小偏角αも１．０４度にして、対称・平行させる。   Here, a structure in which six winding systems are provided in the main girder will be described as an example. Six hoisting machines 1 are installed on the main girder 10, and three hoisting machines 1 are adopted at each end in order to ensure that the deflection angle on the drum and pulley of the wire rope does not exceed the standard regulations, The length b of the main girder is 130 meters, the width a of the upper cover plate is 4 meters, and the wire rope allowable angle of the hoisting machine is ζ ≦ 2 °. Can be calculated to be 1.04 degrees. In this case, one small deviation angle α formed between the drum vertical center line of each base hoisting machine 1 at both ends and the center line continuous line of the guide pulley 2 is also 1.04 degrees. And make them symmetrical and parallel.

巻上げ機１は高さが異なっている巻き上げ機台座７を採用し、ワイヤロープに交差した配置を形成させるとともに、各巻上げ機１からなる各巻上げシステム中の動滑車装置３は連接棒４に連結されることにより、当該巻き上げシステム中の各動滑車装置３の間に固定距離が保持されているので、主桁上部のワイヤロープ間の干渉を防止できる。また、これらの配置によりガイドプーリー２と定滑車装置５間の空間位置が変わっているので、主桁内のワイヤロープと滑車の偏角が規定に符合することを保証するだけでなく、ワイヤロープ間が互いに干渉することも防止できる。   The hoisting machine 1 employs hoisting machine bases 7 having different heights so as to form an arrangement crossing the wire rope, and the moving pulley device 3 in each hoisting system including the hoisting machines 1 is connected to the connecting rod 4. By doing so, since a fixed distance is maintained between the moving pulley devices 3 in the winding system, it is possible to prevent interference between the wire ropes on the upper part of the main beam. Further, since the spatial position between the guide pulley 2 and the fixed pulley device 5 is changed by these arrangements, not only does the wire rope in the main girder and the deflection angle of the pulley match the regulation, the wire rope It is also possible to prevent the gaps from interfering with each other.

そのうち、シングルの巻き上げシステムのワイヤロープ６は巻上げ機１から出てガイドプーリー２を通して定滑車装置５まで到着し、さらに動滑車装置３まで到着した後、動滑車と定滑車の間に繰り返して巻き取り、最終的に主桁上部の定滑車装置側面にある固定端９に固定されることにより、使用する場合吊りポイントがどのように作動されても、ワイヤロープ間の干渉問題が発生することはない。   Among them, the wire rope 6 of the single winding system comes out of the winding machine 1 and arrives at the fixed pulley device 5 through the guide pulley 2 and further arrives at the movable pulley device 3 and then repeatedly wound between the moving pulley and the fixed pulley. And finally fixed to the fixed end 9 on the side of the fixed pulley device at the top of the main girder, no matter how the suspension point is operated, the problem of interference between the wire ropes will occur. Absent.
