Description

防振装置Vibration isolator
　本発明は、振動源である対象物を支持面に対して防振支持する防振装置に関する。 The present invention relates to an anti-vibration device for isolating and supporting an object that is a vibration source on a support surface.
　従来より、振動源である対象物を、支持面に設置された複数の防振装置上に載置することにより、振動が支持面に伝わるのを防止する技術が広く用いられている。その適用例の一つに、風力発電装置を構成する発電機の防振支持がある。 Conventionally, a technique for preventing vibration from being transmitted to a support surface by placing an object that is a vibration source on a plurality of vibration isolation devices installed on the support surface has been widely used. One example of such application is the anti-vibration support of a generator constituting a wind power generator.
　ここで、風力発電装置の構成を簡単に説明する。風力発電装置は、地面に立設されたタワーを有し、その上端に「ナセル」と呼ばれる格納庫が設けられている。このナセルには、風を受ける翼が回転自在に取り付けられている。ナセル内部の水平な床面上には、翼の回転を増速させる増速機と、発電機とが据え付けられている。翼が風を受けて回転すると、この回転が増速機に伝達されて増速される。増速された回転は、増速機の出力軸を介して発電機の駆動軸に伝わる。発電機は、この駆動軸が回転することによって発電する。したがって、増速機の回転が発電機の駆動軸に適切に伝わるようにするために、これら両軸が一直線となるように両機を据え付ける必要がある。 Here, the configuration of the wind power generator will be briefly described. A wind turbine generator has a tower erected on the ground, and a hangar called “nacelle” is provided at the upper end of the tower. A wing for receiving wind is rotatably attached to the nacelle. On the horizontal floor inside the nacelle, a gear box for increasing the rotation of the blades and a generator are installed. When the wing rotates in response to the wind, this rotation is transmitted to the gearbox to increase the speed. The increased rotation is transmitted to the drive shaft of the generator via the output shaft of the speed increaser. The generator generates electricity when the drive shaft rotates. Therefore, in order to appropriately transmit the rotation of the speed increaser to the drive shaft of the generator, it is necessary to install the two machines so that these two axes are in a straight line.
　上記発電機用の防振装置として、例えば特許文献１に開示のものがある。この防振装置は、昇降機構により昇降する軸受台を備え、この軸受台がネジを介して発電機のベース部と連結されている。この軸受台には、当該ベース部が載置される往復台が水平方向の一方向に移動可能なように設けられている。発電機を据え付ける際には、先ず、この防振装置を床面上に複数設置し、その上に発電機を載置する。次に、各軸受台を昇降させると共に各往復台を往復させて、発電機の駆動軸の高さや向きを調整する。最後に、発電機の駆動軸を増速機の出力軸と連結させる。 For example, Patent Document 1 discloses a vibration isolator for the generator. This vibration isolator includes a bearing base that is moved up and down by an elevating mechanism, and this bearing base is connected to the base portion of the generator via a screw. In this bearing stand, a carriage on which the base portion is placed is provided so as to be movable in one horizontal direction. When installing the generator, first, a plurality of the vibration isolator is installed on the floor surface, and the generator is mounted thereon. Next, the height and direction of the drive shaft of the generator are adjusted by raising and lowering each bearing base and reciprocating each carriage. Finally, the generator drive shaft is connected to the gearbox output shaft.

　しかしながら、上記防振装置では、上記往復台の移動方向が固定されているので、往復台上に載置される対象物の水平方向における位置調整の自由度が制限されるという課題がある。 However, in the vibration isolator, since the moving direction of the carriage is fixed, there is a problem that the degree of freedom of position adjustment in the horizontal direction of the object placed on the carriage is limited.
　本発明は、上記のような事情に鑑みてなされたものであり、対象物を支持面に対して防振支持する防振装置において、対象物の水平方向における位置調整の自由度を向上させることができる防振装置を提供することを目的とする。 The present invention has been made in view of the circumstances as described above, and in a vibration isolator that supports a target object in a vibration-isolating manner with respect to a support surface, the degree of freedom in adjusting the position of the target object in the horizontal direction is improved. An object of the present invention is to provide an anti-vibration device capable of performing the above.
　上記目的を達成するために本発明は、対象物を水平方向の所定方向に移動させる水平移動機構を工夫したものである。 In order to achieve the above object, the present invention devised a horizontal movement mechanism for moving an object in a predetermined direction in the horizontal direction.
　具体的には、本発明は、支持面上に設置される基台と、その上に配置されて対象物を支持する支持台と、該支持台と該基台との間に配設されて両者を弾性連結する弾性体と、上記支持台の上に配置され、上記対象物が載置されて該対象物を水平方向の所定方向に移動させる水平移動機構と、を備え、上記対象物を上記支持面に対して防振支持する防振装置を対象とし、次のような解決手段を講じた。 Specifically, the present invention includes a base installed on a support surface, a support base disposed on the base to support an object, and the base between the support base and the base. An elastic body that elastically connects the two, and a horizontal movement mechanism that is disposed on the support base and moves the object in a predetermined direction in the horizontal direction on which the object is placed. The following solution was taken for the anti-vibration device that provides anti-vibration support for the support surface.
　第１の発明は、上記水平移動機構は、上下方向に延びる軸周りに回動可能に構成されていることを特徴とするものである。 The first invention is characterized in that the horizontal movement mechanism is configured to be rotatable around an axis extending in the vertical direction.
　これによれば、対象物を水平方向の所定方向に移動させる水平移動機構が上下方向に延びる軸周りに回動可能である。この水平移動機構を当該軸周りに回動させることにより、対象物の水平方向における移動方向を変更することができる。これにより、対象物の水平方向における位置調整の自由度を向上させることができる。 According to this, the horizontal movement mechanism for moving the object in a predetermined direction in the horizontal direction can be rotated around an axis extending in the vertical direction. By rotating the horizontal movement mechanism around the axis, the moving direction of the object in the horizontal direction can be changed. Thereby, the freedom degree of the position adjustment of the target object in the horizontal direction can be improved.
　第２の発明は、上記第１の発明において、上記支持台から上方に延び、かつ上記対象物と連結する連結軸をさらに備え、上記水平移動機構は、上記連結軸が挿通し且つ該連結軸が上記所定方向に移動可能なように形成された軸孔を有すると共に、上記対象物が載置される水平な載置板部と、上記連結軸が挿通し、かつ上記載置板部が上記所定方向に移動可能なように取り付けられて該載置板部と共に上記連結軸周りに回動可能な回動部材と、上記回動部材に取り付けられ、上記載置部材を上記所定方向に移動させる移動機構と、を有していることを特徴とするものである。 A second invention further includes a connecting shaft extending upward from the support base and connected to the object in the first invention, and the horizontal movement mechanism has the connecting shaft inserted therein and the connecting shaft. Has a shaft hole formed so as to be movable in the predetermined direction, the horizontal placement plate portion on which the object is placed, the connection shaft is inserted, and the placement plate portion is the above A rotating member that is attached so as to be movable in a predetermined direction and is rotatable around the connecting shaft together with the mounting plate portion, and is attached to the rotating member and moves the mounting member in the predetermined direction. And a moving mechanism.
　これによれば、上下方向に延びる連結軸が、対象物が載置される載置板部及びこの載置板部が載置される回動部材を挿通している。そして、この載置板部が回動部材と共に連結軸周りに回動可能である。そうすると、回動部材を連結軸周りに回動することにより、載置板部の水平方向における向きを変更することができる。さらに、載置板部は、連結軸が挿通し且つこの連結軸が水平方向における所定方向に移動可能なように形成された軸孔を有している。そして、この載置板部を当該所定方向に移動させる移動機構をさらに備えている。したがって、この移動機構により、載置板部を水平方向に移動させることができる。以上の構成により、載置板部に対象物が載置された状態で、回動部材を連結軸周りに回動させて載置板部の移動方向を変更し、そして、移動機構によって載置板部を移動させることにより、対象物を水平方向の任意の方向に向け、その方向に移動させることができる。 According to this, the connecting shaft extending in the vertical direction passes through the mounting plate portion on which the object is mounted and the rotating member on which the mounting plate portion is mounted. And this mounting board part can be rotated around a connection axis | shaft with a rotation member. If it does so, the direction in the horizontal direction of a mounting board part can be changed by rotating a rotation member around a connection shaft. Further, the mounting plate portion has a shaft hole formed so that the connecting shaft is inserted and the connecting shaft is movable in a predetermined direction in the horizontal direction. And the moving mechanism which moves this mounting board part to the said predetermined direction is further provided. Therefore, the placement mechanism can be moved in the horizontal direction by this moving mechanism. With the above configuration, in a state where the object is placed on the placing plate portion, the turning member is turned around the connecting shaft to change the moving direction of the placing plate portion, and the placing mechanism is placed by the moving mechanism. By moving the plate portion, the object can be directed in the horizontal direction and moved in that direction.
　第３の発明は、上記第２の発明において、上記移動機構は、上記載置板部の外周縁における上記所定方向一方側から上記回動部材と干渉しないように下方に延び、かつ該所定方向に貫通する貫通孔が形成された縦板部と、上記縦板部から上記所定方向に間隔をあけて該縦板部と対向するように上記回動部材に設けられ、かつ該所定方向に貫通する貫通孔が形成された対向板部と、上記両貫通孔のうち上記所定方向他方側の貫通孔の周縁に設けられたナットと、上記所定方向一方側の貫通孔を挿通して上記ナットと螺合するボルトと、を有し、上記載置板部は、上記ボルトの回転によって上記ナットが該ボルトに沿って移動することにより、上記所定方向に移動するように構成されていることを特徴とするものである。 In a third aspect based on the second aspect, the moving mechanism extends downward from one side in the predetermined direction on the outer periphery of the mounting plate portion so as not to interfere with the rotating member, and the predetermined direction. A vertical plate portion having a through-hole penetrating therethrough, and provided in the rotating member so as to face the vertical plate portion with a space in the predetermined direction from the vertical plate portion, and penetrates in the predetermined direction. An opposing plate portion formed with a through hole, a nut provided on the periphery of the through hole on the other side in the predetermined direction among the through holes, and the nut inserted through the through hole on the one side in the predetermined direction. And the mounting plate portion is configured to move in the predetermined direction when the nut moves along the bolt by the rotation of the bolt. It is what.
　これによれば、載置板部の上記所定方向一方側の外周縁から下方に縦板部が延びると共に、回動部材に当該縦板部と対向する対向板部が設けられ、これら縦板部及び対向板部の各々に水平方向の所定方向に貫通する貫通孔が形成されている。そして、上記所定方向一方側の貫通孔の周縁にナットが設けられると共に他方側の貫通孔を挿通するボルトが該ナットと螺合している。そうすると、ボルトを回転させることによってナットがボルトに沿って移動し、縦板部及び対向板部が互いに接近又は離間する。一方、回動部材は連結軸周りを回動するだけで、上記所定方向に移動しない。したがって、この回動部材と一体の対向板部と、連結軸との間の距離が一定に保持される。 According to this, the vertical plate portion extends downward from the outer peripheral edge on one side in the predetermined direction of the mounting plate portion, and the rotating plate is provided with the opposing plate portion facing the vertical plate portion. And the through-hole penetrated in the predetermined direction of a horizontal direction is formed in each of an opposing board part. A nut is provided at the periphery of the through hole on one side in the predetermined direction, and a bolt inserted through the through hole on the other side is screwed with the nut. If it does so, a nut will move along a volt | bolt by rotating a volt | bolt, and a vertical board part and an opposing board part will mutually approach or space apart. On the other hand, the rotating member only rotates around the connecting shaft and does not move in the predetermined direction. Therefore, the distance between the counter plate portion integral with the rotating member and the connecting shaft is kept constant.
　そうすると、ボルトが回転することにより、連結軸との間の距離が一定である対向板部に対して縦板部が接近又は離間するため、この縦板部と一体の載置板部が連結軸に対して上記所定方向に相対移動することができる。よって、ボルトを回すことにより、この載置板部上に載置される対象物を上記所定方向に移動させることができる。また、ボルトを回すという簡単な操作で、対象物を上記所定方向に移動させることができる。 Then, as the bolt rotates, the vertical plate portion approaches or separates from the opposing plate portion having a constant distance from the connection shaft, so that the mounting plate portion integrated with the vertical plate portion is connected to the connection shaft. Relative to the predetermined direction. Therefore, by turning the bolt, the object placed on the placement plate portion can be moved in the predetermined direction. Further, the object can be moved in the predetermined direction by a simple operation of turning the bolt.
　第４の発明は、上記第２又は第３の発明において、上記軸孔は、長軸方向が上記所定方向と一致する長孔であることを特徴とするのである。 The fourth invention is characterized in that, in the second or third invention, the shaft hole is a long hole whose major axis direction coincides with the predetermined direction.
　これによれば、上記軸孔が、長軸方向が上記所定方向と一致する長孔であるため、上記所定方向と直交する方向における載置板部の移動が規制される。このため、載置板部を水平方向に移動させる際に、載置板部を、上記所定方向と直交する方向にガタつくことなくスムーズに移動させることができる。 According to this, since the shaft hole is a long hole whose major axis direction coincides with the predetermined direction, the movement of the mounting plate portion in the direction orthogonal to the predetermined direction is restricted. For this reason, when moving a mounting board part to a horizontal direction, a mounting board part can be moved smoothly, without rattling in the direction orthogonal to the said predetermined direction.
　第５の発明は、上記第２又は第３の発明において、上記軸孔は、上記連結軸よりも大径の円孔であることを特徴とするものである。 The fifth invention is characterized in that, in the second or third invention, the shaft hole is a circular hole having a diameter larger than that of the connecting shaft.
　これによれば、載置板部の軸孔が連結軸よりも大径の円孔であるため、載置板部が水平方向の任意の方向に移動するのが許容される。したがって、例えば、複数の防振装置で対象物を防振支持し、所定の防振装置だけを操作して載置板部を水平方向に移動させて対象物の水平方向における位置を調整する場合に、その他の防振装置の載置板部が当該対象物の移動に伴って水平方向に移動することができる。 According to this, since the shaft hole of the mounting plate portion is a circular hole having a diameter larger than that of the connecting shaft, the mounting plate portion is allowed to move in any horizontal direction. Therefore, for example, when the object is supported in a vibration-proof manner by a plurality of vibration isolators, and the position of the object in the horizontal direction is adjusted by moving only the predetermined vibration isolator to move the mounting plate portion in the horizontal direction. In addition, the placement plate portion of the other vibration isolator can move in the horizontal direction as the object moves.
　第６の発明は、上記第１～第５のいずれかの発明において、上記水平移動機構が上下方向に延びる軸周りに回動可能なように取り付けられ、上記対象物を上下方向に移動させる上下移動機構をさらに備えることを特徴とするものである。 According to a sixth invention, in any one of the first to fifth inventions, the horizontal movement mechanism is attached so as to be rotatable about an axis extending in the vertical direction, and the vertical movement for moving the object in the vertical direction. A moving mechanism is further provided.
　これによれば、上下移動機構により、対象物の水平方向における位置調整だけでなく、上下方向における位置調整も可能となる。 According to this, not only the horizontal position adjustment of the object but also the vertical position adjustment can be performed by the vertical movement mechanism.
　本発明によれば、対象物が載置される載置板部を水平方向に移動させる水平移動機構が上下方向に延びる軸周りに回動可能であるため、載置板部を水平方向の任意の方向に移動させることができる。したがって、対象物の水平方向における位置調整の自由度を向上させることが可能となる。 According to the present invention, since the horizontal movement mechanism that moves the placement plate portion on which the object is placed in the horizontal direction can rotate around the axis extending in the vertical direction, the placement plate portion can be moved in the horizontal direction. It can be moved in the direction. Therefore, it is possible to improve the degree of freedom in adjusting the position of the object in the horizontal direction.

The following description of the preferred embodiment is merely exemplary in nature. This embodiment demonstrates the example which applied the vibration isolator of this invention to the vibration proof support of the generator for wind power generators.
　図１は、本発明の実施形態に係る防振装置１を複数備えた風力発電装置８０を示す一部切欠斜視図である。この風力発電装置８０は、地面に直立するタワー９０を有し、その最上部に略直方体状のナセル１００が設けられている。このナセル１００の内部には、増速機１１０及び発電機１２０が直線状に並ぶように据え付けられている。発電機１２０は、水平な床面（支持面）１００ａ上に設置された４基の防振装置１，１，…によって防振支持されている。各防振装置１は、発電機１２０のベース部の四隅部１２０ａを支持している。発電機１２０の駆動軸は、増速機１１０の出力軸と一直線となるように連結されている。尚、図１において、紙面奥に配置された２基の防振装置１，１が隠れている。また、図１において、各防振装置１を簡略化すると共に、増速機１１０の出力軸と発電機１２０の駆動軸とを連結したものを軸連結部１３０として簡略化している。以下、この軸連結部１３０の延びる方向をＸ方向とし、このＸ方向と直交する方向をＹ方向として説明する。 FIG. 1 is a partially cutaway perspective view showing a wind turbine generator 80 including a plurality of vibration isolator 1 according to an embodiment of the present invention. This wind power generator 80 has a tower 90 upright on the ground, and a substantially rectangular parallelepiped nacelle 100 is provided on the top thereof. Inside the nacelle 100, the speed increaser 110 and the generator 120 are installed in a straight line. The generator 120 is supported by vibration isolation by four vibration isolation devices 1, 1,... Installed on a horizontal floor surface (support surface) 100a. Each vibration isolator 1 supports the four corners 120 a of the base portion of the generator 120. The drive shaft of the generator 120 is connected to the output shaft of the speed increaser 110 so as to be in a straight line. In FIG. 1, the two vibration isolators 1 and 1 arranged in the back of the page are hidden. Further, in FIG. 1, each vibration isolator 1 is simplified, and the shaft connecting portion 130 is simplified by connecting the output shaft of the speed increaser 110 and the drive shaft of the generator 120.

　上記防振装置１について図２～６を参照して説明する。各図は防振装置１を示しており、図２は斜視図、図３は分解斜視図、図４は平面図、図５は図４の矢印V方向から視た側面図、図６は図４の矢印VI方向から視た側面図である。 The vibration isolator 1 will be described with reference to FIGS. FIG. 2 is a perspective view, FIG. 3 is an exploded perspective view, FIG. 4 is a plan view, FIG. 5 is a side view seen from the direction of arrow V in FIG. 4, and FIG. It is the side view seen from the arrow VI direction of 4.
　上記防振装置１は、上記床面１００ａ上に設置される略ハット状の基台２と、この基台２の上方に配設された上側円錐台状の支持台３と、基台２と支持台３との間に配設されて両者を弾性連結するゴム弾性体４（図５参照）と、を備えている。このゴム弾性体４は、支持台３上の発電機１２０が発生する振動を減衰させて、振動が上記床面１００ａに伝わるのを抑制している。 The vibration isolator 1 includes a substantially hat-shaped base 2 installed on the floor surface 100a, an upper frustoconical support 3 disposed above the base 2, and a base 2. And a rubber elastic body 4 (see FIG. 5) which is disposed between the support 3 and elastically connects the two. The rubber elastic body 4 attenuates the vibration generated by the generator 120 on the support base 3 and suppresses the vibration from being transmitted to the floor surface 100a.
　上記基台２は、金属製であって、四隅部にボルト挿通孔２ａが貫通形成された矩形板状の底部２ｂと、この中央部に上方に突出するように円錐台状に形成された凸部２ｃと、を有している。上記ボルト挿通孔２ａ，２ａ…には、防振装置１を上記床面１００ａに固定するための固定ボルトＢ（図７参照）が挿通する。上記凸部２ｃの中央部には、上記支持台３の後述するボス部３ａ（図５参照）が挿通する孔が形成されている。 The base 2 is made of metal, and has a rectangular plate-like bottom 2b in which bolt insertion holes 2a are formed at the four corners, and a convex formed in a truncated cone shape so as to protrude upward at the center. Part 2c. A fixing bolt B (see FIG. 7) for fixing the vibration isolator 1 to the floor surface 100a is inserted through the bolt insertion holes 2a, 2a. A hole through which a boss portion 3a (see FIG. 5) described later of the support base 3 is inserted is formed in the central portion of the convex portion 2c.
　上記支持台３は、金属製であって、上記凸部２ｃの上方に配置され、この凸部２ｃを覆うような円錐台状をなしている。上記ゴム弾性体４は、上記凸部２ｃと支持台３との間に配設されて、両者を弾性連結している。支持台３の中央部には、下方に延びる円筒状のボス部３ａが形成されている。このボス部３ａの内周には、雌ネジが形成されている。ボス部３ａの中空部からは、鉄丸棒からなる連結軸５が上方に延びている。この連結軸５の上端部５ａには、上記発電機１２０の四隅部１２０ａを固定するためのナット（不図示）と螺合する雄ネジが形成されている。この螺合により、連結軸５が上記四隅部１２０ａと連結している。連結軸５の下端部には、雄ネジが形成されている。この雄ネジがボス部３ａの雌ネジと螺合することにより、連結軸５が支持台３に固定されている。 The support base 3 is made of metal and has a truncated cone shape that is disposed above the convex portion 2c and covers the convex portion 2c. The rubber elastic body 4 is disposed between the convex portion 2c and the support base 3, and elastically connects the two. A cylindrical boss 3 a extending downward is formed at the center of the support 3. A female screw is formed on the inner periphery of the boss 3a. From the hollow part of the boss | hub part 3a, the connection shaft 5 which consists of an iron round bar is extended upwards. The upper end portion 5 a of the connecting shaft 5 is formed with a male screw that is screwed with a nut (not shown) for fixing the four corner portions 120 a of the generator 120. By this screwing, the connecting shaft 5 is connected to the four corners 120a. A male screw is formed at the lower end of the connecting shaft 5. The male shaft is screwed with the female screw of the boss portion 3 a, so that the connecting shaft 5 is fixed to the support base 3.
　上記連結軸５は、上記支持台３の上に設けられた略円柱状の昇降部材６と、この昇降部材６の上に配置され、上記発電機１２０の四隅部１２０ａが載置される水平な載置板部７０と、を挿通している。 The connecting shaft 5 is a substantially cylindrical lifting member 6 provided on the support base 3 and is disposed on the lifting member 6. The connecting shaft 5 is a horizontal surface on which the four corners 120 a of the generator 120 are placed. The mounting plate portion 70 is inserted therethrough.
　上記昇降部材６は、金属製の略円柱状部材であって、その中央部には、上下方向に貫通する貫通孔６０ａが形成されている。貫通孔６０ａには、雌ネジが形成されている。一方、上記連結軸５の昇降部材６に対応する部位には、雄ネジが形成されている。そして、この部位と上記貫通孔６０ａとが螺合している。昇降部材６を水平方向に回動すると、この昇降部材６は連結軸５に沿って上下方向に移動する。 The elevating member 6 is a substantially cylindrical member made of metal, and a through hole 60a penetrating in the vertical direction is formed at the center thereof. A female screw is formed in the through hole 60a. On the other hand, a male screw is formed at a portion corresponding to the elevating member 6 of the connecting shaft 5. And this site | part and the said through-hole 60a are screwing together. When the elevating member 6 is rotated in the horizontal direction, the elevating member 6 moves in the vertical direction along the connecting shaft 5.
　上記昇降部材６は、円柱状の本体部６０と、この本体部６０の上部に設けられ、本体部６０よりも小径の縮径部６１と、本体部６０の下部に形成された円環状の鍔部６２と、を有している。本体部６０の外周面６０ｃには、径方向に延び且つ該外周面６０ｃに開口する円穴６０ｂ，６０ｂ，…が周方向に９０°間隔で形成されている。この円穴６０ｂ，６０ｂ，…に、例えば鉄棒を差し込んで水平方向に回すと、昇降部材６が昇降する。この昇降部材６に、上記載置板部７０を上記連結軸５周りに回動させる回動部材７が取り付けられている。 The elevating member 6 is provided with a cylindrical main body 60, an upper portion of the main body 60, a reduced diameter portion 61 having a smaller diameter than the main body 60, and an annular bowl formed at the lower portion of the main body 60. Part 62. On the outer peripheral surface 60c of the main body 60, circular holes 60b, 60b,... Extending in the radial direction and opening in the outer peripheral surface 60c are formed at 90 ° intervals in the circumferential direction. When, for example, a steel bar is inserted into the circular holes 60b, 60b,. A rotating member 7 that rotates the mounting plate portion 70 around the connecting shaft 5 is attached to the elevating member 6.
　上記載置板部７０は、上記昇降部材６よりも大径の円形状鋼板からなる。載置板部７０の中央部には、上記連結軸５が挿通する軸孔７０ａが厚み方向に貫通形成されている。この軸孔７０ａは、トラック状の長孔である。軸孔７０ａの長軸方向（所定方向）の長さは、連結軸５の径よりも大きく、短軸方向の長さは、該連結軸５とほぼ同一径である。したがって、連結軸５は、この軸孔７０ａを挿通した状態で、この軸孔７０ａの長軸方向に移動可能である。よって、載置板部７０は、この長軸方向にスライド移動することができる。載置板部７０の外周縁の上記長軸方向一方側には、下方に折れ曲がる縦板部７４が設けられている。そうすると、上記のように載置板部７０が上記長軸方向に移動可能なため、この縦板部７４も当該長軸方向に移動することができる。言い換えると、縦板部７４と上記連結軸５との間の距離は可変である。 The mounting plate portion 70 is made of a circular steel plate having a diameter larger than that of the elevating member 6. A shaft hole 70a through which the connecting shaft 5 is inserted is formed in the center portion of the mounting plate portion 70 in the thickness direction. The shaft hole 70a is a track-like long hole. The length in the major axis direction (predetermined direction) of the shaft hole 70 a is larger than the diameter of the connecting shaft 5, and the length in the minor axis direction is almost the same diameter as the connecting shaft 5. Therefore, the connecting shaft 5 is movable in the major axis direction of the shaft hole 70a while being inserted through the shaft hole 70a. Therefore, the mounting plate portion 70 can slide in the long axis direction. A vertical plate portion 74 that is bent downward is provided on one side in the major axis direction of the outer peripheral edge of the mounting plate portion 70. Then, since the mounting plate portion 70 can move in the long axis direction as described above, the vertical plate portion 74 can also move in the long axis direction. In other words, the distance between the vertical plate portion 74 and the connecting shaft 5 is variable.
　上記縦板部７４の中央部には、その厚み方向に貫通する貫通孔７４ａが形成されている。縦板部７４の上記長軸方向一方側側面には、貫通孔７４ａと同軸の六角ナット７５が溶接固定されている。縦板部７４は、上記回動部材７の後述する上側回動板部７１に設けられた差込孔７６ａに差し込まれている。 At the center of the vertical plate portion 74, a through hole 74a that penetrates in the thickness direction is formed. A hexagonal nut 75 coaxial with the through hole 74a is welded and fixed to one side surface in the major axis direction of the vertical plate portion 74. The vertical plate portion 74 is inserted into an insertion hole 76 a provided in an upper rotation plate portion 71 (described later) of the rotation member 7.
　上記回動部材７は、上記載置板部７０が載置され且つ上記連結軸５周りに回動する上側回動板部７１と、この上側回動板部７１の下方に配置されて上側回動板部７１と共に回動する下側回動板部７２と、両回動板部７１，７２を互いに連結する連結板部７７と、を有している。 The rotating member 7 includes an upper rotating plate portion 71 on which the mounting plate portion 70 is mounted and rotates around the connecting shaft 5, and is disposed below the upper rotating plate portion 71 so as to rotate upward. It has a lower rotating plate portion 72 that rotates together with the moving plate portion 71, and a connecting plate portion 77 that connects the rotating plate portions 71 and 72 to each other.
　上記上側回動板部７１は、図４に示すように、上記長軸方向に長い略矩形鋼板からなる。上側回動板部７１の上記長軸方向他方側部分は半円をなし、図５に示すように、この半円部分から当該長軸方向中央部に亘って円孔７１ａが厚み方向に貫通形成されている。この円孔７１ａは、上記昇降部材６の縮径部６１より僅かに大径であり、この縮径部６１が緩やかに嵌っている。上側回動板部７１は、上記本体部６０の上面６１ｄに載置されている。したがって、この上側回動板部７１は、縮径部６１周りに、言い換えると、連結軸５周りに回動することができる。その一方で、上側回動板部７１は、上記縮径部６１によって上記長軸方向への移動が規制されている。 As shown in FIG. 4, the upper rotating plate portion 71 is made of a substantially rectangular steel plate that is long in the long axis direction. The other side portion in the major axis direction of the upper rotating plate portion 71 forms a semicircle, and as shown in FIG. 5, a circular hole 71a is formed penetrating from the semicircle portion to the center portion in the major axis direction in the thickness direction. Has been. The circular hole 71a is slightly larger in diameter than the reduced diameter portion 61 of the elevating member 6, and the reduced diameter portion 61 is gently fitted. The upper rotating plate portion 71 is placed on the upper surface 61 d of the main body portion 60. Therefore, the upper rotation plate portion 71 can rotate around the reduced diameter portion 61, in other words, around the connecting shaft 5. On the other hand, the movement of the upper rotating plate portion 71 in the major axis direction is restricted by the reduced diameter portion 61.
　また、上側回動板部７１の上記円孔７１ａよりも上記所定方向一方側には、上記差込孔７６ａが厚み方向に貫通形成されている。この差込孔７６ａは、上下方向から見てハット状をなし、上記長軸方向一方側部分が他方側部分よりも幅狭となっている。また、この差込孔７６ａの上記長軸方向幅は、上記載置板部７０の縦板部７４の厚みよりも大きい。したがって、この差込孔７６ａに差し込まれる上記縦板部７４は、差込孔７６ａ内を上記長軸方向に移動することができる。さらに、上側回動板部７１の差込孔７６ａよりも上記長軸方向一方側には、比較的小さな六角ボルトからなる一対の小ボルト７９，７９が上下方向に挿通固定されている。 Further, the insertion hole 76a is formed in the thickness direction on the one side in the predetermined direction with respect to the circular hole 71a of the upper rotating plate portion 71. The insertion hole 76a has a hat shape when viewed from the vertical direction, and the one side portion in the major axis direction is narrower than the other side portion. Further, the width in the major axis direction of the insertion hole 76a is larger than the thickness of the vertical plate portion 74 of the mounting plate portion 70 described above. Therefore, the vertical plate portion 74 inserted into the insertion hole 76a can move in the major axis direction within the insertion hole 76a. Further, a pair of small bolts 79, 79 made of relatively small hexagon bolts are inserted and fixed in the vertical direction on one side in the long axis direction from the insertion hole 76 a of the upper rotating plate portion 71.
　上記下側回動板部７２は、上記上側回動板部７１とほぼ同一形状の鋼板からなる。この下側回動板部７２は、上下方向から見て上側回動板部７１と重なるように配置されている。下側回動板部７２の上記長軸方向他方側部分は半円をなし、この半円部分から当該長軸方向中央部に亘って円孔７２ａが厚み方向に貫通形成されている。この円孔７２ａは、上記昇降部材６の本体部６０より僅かに大径であり、この本体部６０が緩やかに嵌っている。そして、この下側回動板部７２は、上記鍔部６２の上面６２ａに載置されている。したがって、この下側回動板部７２は、昇降部材６周りに、言い換えると、連結軸５周りに回動することができる。その一方で、下側回動板部７２は、本体部６０によって上記長軸方向への移動が規制されている。 The lower rotating plate portion 72 is made of a steel plate having substantially the same shape as the upper rotating plate portion 71. The lower rotation plate portion 72 is disposed so as to overlap the upper rotation plate portion 71 when viewed from the vertical direction. The other side portion in the major axis direction of the lower rotating plate portion 72 forms a semicircle, and a circular hole 72a is formed penetrating in the thickness direction from the semicircle portion to the central portion in the major axis direction. The circular hole 72a has a slightly larger diameter than the main body portion 60 of the elevating member 6, and the main body portion 60 fits gently. And this lower side rotation board part 72 is mounted in the upper surface 62a of the said collar part 62. As shown in FIG. Therefore, the lower rotation plate portion 72 can rotate around the elevating member 6, in other words, around the connecting shaft 5. On the other hand, the movement of the lower rotation plate portion 72 in the long axis direction is restricted by the main body portion 60.
　上記連結板部７７は、長手方向両端部が互いに平行かつ対向するように曲げ加工された矩形鋼板からなる。この連結板部７７は、上記縦板部７４と対向する対向板部７７ａと、この対向板部７７ａの長手方向両端から垂直に延びる一対の側板部７７ｂ，７７ｂと、を有している。上記対向板部７７ａは、上記両回動板部７１，７２における上記長軸方向一方側端面に固定されている。上記各側板部７７ｂは、上記両回動板部７１，７２における上記長軸方向と直交する直交方向一方側端面に固定されている。そして、前述通り両回動板部７１，７２の上記長軸方向への移動が規制されているため、上記対向板部７７ａも当該長軸方向への移動が規制されている。言い換えると、対向板部７７ａと上記連結軸５との間の距離は一定に保持されている。 The connecting plate portion 77 is made of a rectangular steel plate that is bent so that both end portions in the longitudinal direction are parallel to and opposed to each other. The connecting plate portion 77 includes a counter plate portion 77a that faces the vertical plate portion 74, and a pair of side plate portions 77b and 77b that extend vertically from both longitudinal ends of the counter plate portion 77a. The counter plate portion 77a is fixed to the one end surface in the major axis direction of the both rotating plate portions 71 and 72. Each of the side plate portions 77b is fixed to one end surface in the orthogonal direction orthogonal to the major axis direction of the rotating plate portions 71 and 72. As described above, since the movement of both the rotating plate portions 71 and 72 in the long axis direction is restricted, the movement of the counter plate portion 77a in the long axis direction is also restricted. In other words, the distance between the opposing plate portion 77a and the connecting shaft 5 is kept constant.
　上記対向板部７７ａの中央部には、その厚み方向に貫通する貫通孔７７ｃが形成されている。この貫通孔７７ｃを、上記長軸方向一方側から六角ボルト（ボルト）７８が挿通している。この六角ボルト７８の軸部は、上記六角ナット７５と螺合すると共に、上記縦板部７４の貫通孔７４ａを挿通している。ここで、両貫通孔７４ａ，７７ｃは上記長軸方向に貫通形成されているので、これらを挿通する六角ボルト７８は当該長軸方向に延びている。また、この軸部の基端部は残部よりも小径であり、この小径部分に上記一対の小ボルト７９，７９が係合している。したがって、六角ボルト７８は、一対の小ボルト７９，７９によって、対向板部７７ａに対する上記長軸方向への相対移動が規制されている。そうすると、前述通り対向板部７７ａと連結軸５との間の距離が一定であるため、六角ボルト７８と連結軸５との間の距離も一定となっている。 A through hole 77c penetrating in the thickness direction is formed in the central portion of the opposing plate portion 77a. A hexagonal bolt (bolt) 78 is inserted through the through-hole 77c from one side in the long axis direction. The shaft portion of the hexagon bolt 78 is screwed with the hexagon nut 75 and is inserted through the through hole 74 a of the vertical plate portion 74. Here, since both the through- holes 74a and 77c are penetrated and formed in the said major axis direction, the hexagon bolt 78 which penetrates these extends in the said major axis direction. In addition, the base end portion of the shaft portion has a smaller diameter than the remaining portion, and the pair of small bolts 79 and 79 are engaged with the small diameter portion. Accordingly, the hexagonal bolt 78 is regulated by the pair of small bolts 79, 79 from relative movement in the long axis direction with respect to the opposing plate portion 77a. Then, since the distance between the opposing plate portion 77a and the connecting shaft 5 is constant as described above, the distance between the hexagon bolt 78 and the connecting shaft 5 is also constant.
　以上の構成において、前述の通り六角ボルト７８と連結軸５との間の距離が一定に保持されており、この六角ボルト７８が正逆回転すると、その軸部に沿って、すなわち上記長軸方向に六角ナット７５が往復移動する。したがって、六角ナット７５は、上記長軸方向において連結軸５に対して接近又は離間する。一方、この六角ナット７５は、載置板部７０と一体に設けられている。したがって、載置板部７０は、六角ボルト７８が正逆回転して六角ナット７５が該六角ボルト７８の軸部を往復移動することにより、上記長軸方向に往復移動することができる。このように、縦板部７４、六角ナット７５、対向板部７７ａ及び六角ボルト７８は、載置板部７０を上記長軸方向に往復移動させる移動機構を構成している。 In the above configuration, the distance between the hexagon bolt 78 and the connecting shaft 5 is kept constant as described above, and when the hexagon bolt 78 rotates forward and backward, along the shaft portion, that is, the long axis direction. The hexagon nut 75 moves back and forth. Therefore, the hexagon nut 75 approaches or separates from the connecting shaft 5 in the long axis direction. On the other hand, the hexagon nut 75 is provided integrally with the mounting plate portion 70. Therefore, the mounting plate portion 70 can reciprocate in the long axis direction when the hexagon bolt 78 rotates forward and backward and the hexagon nut 75 reciprocates along the shaft portion of the hexagon bolt 78. Thus, the vertical plate portion 74, the hexagon nut 75, the opposing plate portion 77a, and the hexagon bolt 78 constitute a moving mechanism that reciprocates the mounting plate portion 70 in the long axis direction.
　さらに、連結板部７７を水平方向に回動させると、これと一体に両回動板部７１，７２及び載置板部７０が連結軸５周りに回動する。したがって、載置板部７０、回動部材７、六角ナット７５及び六角ボルト７８は、載置された発電機１２０を上記長軸方向に移動させると共に、上下方向に延びる連結軸５周りに回動する水平移動機構を構成している。 Further, when the connecting plate portion 77 is rotated in the horizontal direction, both the rotating plate portions 71 and 72 and the mounting plate portion 70 are rotated around the connecting shaft 5 integrally therewith. Therefore, the mounting plate portion 70, the rotating member 7, the hexagon nut 75, and the hexagon bolt 78 move the mounted generator 120 in the long axis direction and rotate around the connecting shaft 5 extending in the vertical direction. The horizontal movement mechanism is configured.
　また、載置板部７０及び回動部材７は、図４等に示すように、昇降部材６に取り付けられた状態で、この昇降部材６が水平方向に回動することにより、上下方向に移動する。したがって、昇降部材６及び連結軸５は、載置板部７０上に載置される発電機１２０を上下方向に移動させる上下移動機構を構成している。 Further, as shown in FIG. 4 and the like, the mounting plate portion 70 and the rotating member 7 move in the vertical direction by rotating the lifting member 6 in the horizontal direction while being attached to the lifting member 6. To do. Accordingly, the elevating member 6 and the connecting shaft 5 constitute a vertical movement mechanism that moves the generator 120 mounted on the mounting plate portion 70 in the vertical direction.
　－発電機の据付方法－
　次に、発電機１２０を床面１００ａに据え付ける手順を、主に図１及び図７を参照して説明する。図７は、図１の矢印VII方向から視た防振装置１を示す側面図である。尚、発電機１２０を据え付ける際には、予め増速機１１０が床面１００ａ上に据え付けられている。また、発電機１２０のベース部の四隅部１２０ａ，１２０ａ，…には、連結軸５よりも大径の取付孔１２０ｂ，１２０ｂ，…が形成されている。 -How to install the generator-
Next, a procedure for installing the generator 120 on the floor surface 100a will be described mainly with reference to FIGS. FIG. 7 is a side view showing the vibration isolator 1 viewed from the direction of arrow VII in FIG. In addition, when installing the generator 120, the gearbox 110 is installed in advance on the floor surface 100a. Further, mounting holes 120b, 120b,... Having a diameter larger than that of the connecting shaft 5 are formed at the four corners 120a, 120a,.
　先ず、床面１００ａにおける発電機１２０の据付箇所に、４基の防振装置１，１，…を設置する。次に、発電機１２０を吊り上げて、上記取付孔１２０ｂ，１２０ｂ，…にそれぞれ連結軸５を通し、発電機１２０の駆動軸がＸ方向に延びるように載置板部７０，７０，…上に載置して、各連結軸５の上端部５ａにナットを仮締めする。 First, four vibration isolation devices 1, 1,... Are installed at the installation location of the generator 120 on the floor surface 100a. Next, the generator 120 is lifted, the connecting shafts 5 are respectively passed through the mounting holes 120b, 120b,..., And the mounting plates 70, 70,. The nut is placed and temporarily tightened to the upper end 5a of each connecting shaft 5.
　続いて、各昇降部材６を水平方向に回動して、発電機１２０の駆動軸の高さを増速機１１０の出力軸の高さに合わせる。次に、各防振装置１の側板部７７ｂ，７７ｂをプラスチックハンマ等で叩いて載置板部７０を連結軸５周りに回動させて載置板部７０の向きを調節し、六角ボルト７８を回して発電機１２０の駆動軸が増速機１１０の出力軸と直線状になるようにする。そして、発電機１２０の駆動軸と増速機１１０の出力軸とを連結する。 Subsequently, each lifting member 6 is rotated in the horizontal direction so that the height of the drive shaft of the generator 120 is adjusted to the height of the output shaft of the speed increaser 110. Next, the side plate portions 77b and 77b of each vibration isolator 1 are struck with a plastic hammer or the like to rotate the mounting plate portion 70 around the connecting shaft 5 to adjust the orientation of the mounting plate portion 70, and the hexagon bolt 78 , So that the drive shaft of the generator 120 is linear with the output shaft of the speed increaser 110. And the drive shaft of the generator 120 and the output shaft of the gearbox 110 are connected.
　最後に、仮締めしたボルトを締めて発電機１２０を防振装置１，１，…に固定する。以上の手順により、発電機１２０の駆動軸と増速機１１０の出力軸とが一直線になるように連結した状態で、発電機１２０を床面１００ａ上に設置することができる。 Finally, the temporarily tightened bolts are tightened to fix the generator 120 to the vibration isolator 1, 1,. With the above procedure, the generator 120 can be installed on the floor surface 100a in a state where the drive shaft of the generator 120 and the output shaft of the speed increaser 110 are connected so as to be in a straight line.
　ところで、発電機１２０の水平位置を調整するときに、発電機１２０がその重心を中心に水平方向に回転することがある。その場合、発電機１２０の駆動軸の延びる方向が増速機１１０の出力軸の延びる方向と交差する虞がある。このように回転した発電機１２０の向きを是正するには、発電機１２０の四隅部１２０ａ，１２０ａ，…を発電機１２０の重心に向かって移動させる必要がある。 By the way, when the horizontal position of the generator 120 is adjusted, the generator 120 may rotate in the horizontal direction around its center of gravity. In that case, the direction in which the drive shaft of the generator 120 extends may intersect the direction in which the output shaft of the speed increaser 110 extends. In order to correct the direction of the generator 120 rotated in this way, it is necessary to move the four corners 120a, 120a, ... of the generator 120 toward the center of gravity of the generator 120.
　特許文献１に開示の従来タイプの防振装置では、上記四隅部１２０ａが載置される往復台の移動方向が固定されている。そうすると、４基の防振装置のうち、例えば２基を往復台がＸ方向に移動するように設置し、残りの２基をＹ方向に移動するように設置した上で、各防振装置を操作して発電機１２０の水平方向の向きを是正しなければならない。したがって、発電機１２０の向きを是正するのに手間がかかる。 In the conventional vibration isolator disclosed in Patent Document 1, the moving direction of the carriage on which the four corners 120a are placed is fixed. Then, among the four vibration isolators, for example, two units are installed so that the carriage moves in the X direction, and the remaining two units are installed so as to move in the Y direction. It must be manipulated to correct the horizontal orientation of the generator 120. Therefore, it takes time to correct the direction of the generator 120.
　一方、本実施形態の防振装置１は、載置板部７０を水平方向における任意の方向に移動させることができる。したがって、１基の防振装置１を操作するだけで発電機１２０の向きを是正することができる。よって、この防振装置１を用いることで、発電機１２０の水平方向における向きを従来よりも簡単に是正することができる。 On the other hand, the vibration isolator 1 of the present embodiment can move the mounting plate portion 70 in an arbitrary direction in the horizontal direction. Therefore, the direction of the generator 120 can be corrected only by operating one vibration isolator 1. Therefore, by using this vibration isolator 1, the direction of the generator 120 in the horizontal direction can be corrected more easily than before.
　≪効果≫
　上記実施形態によれば、発電機１２０の四隅部１２０ａを水平方向の所定方向に移動させる上記水平移動機構が、上下方向に延びる連結軸５周りに回動可能である。このため、この水平移動機構を当該連結軸５周りに回動させることにより、上記四隅部１２０ａの水平方向における移動方向を変更することができる。したがって、発電機１２０の水平方向における位置調整の自由度を向上させることができる。 ≪Effect≫
According to the embodiment, the horizontal movement mechanism that moves the four corners 120a of the generator 120 in a predetermined direction in the horizontal direction can rotate around the connecting shaft 5 extending in the vertical direction. For this reason, the horizontal moving direction of the four corners 120a can be changed by rotating the horizontal moving mechanism around the connecting shaft 5. Therefore, the freedom degree of the position adjustment of the generator 120 in the horizontal direction can be improved.
　また、上記実施形態によれば、連結軸５が、発電機１２０の四隅部１２０ａが載置される載置板部７０及びこの載置板部７０が載置される回動部材７を挿通している。さらに、この載置板部７０が回動部材７と共に連結軸５周りに回動可能である。したがって、載置板部７０を連結軸５周りに回動することにより、載置板部７０の水平方向における向きを変更することができる。 Moreover, according to the said embodiment, the connection shaft 5 penetrates the mounting board part 70 in which the four corner parts 120a of the generator 120 are mounted, and the rotation member 7 in which this mounting board part 70 is mounted. ing. Further, the mounting plate portion 70 can rotate around the connecting shaft 5 together with the rotating member 7. Therefore, the orientation of the placement plate portion 70 in the horizontal direction can be changed by rotating the placement plate portion 70 around the connecting shaft 5.
　さらに、載置板部７０には、連結軸５が水平方向における所定方向に移動可能なように軸孔７０ａが形成されている。そして、この載置板部７０を当該所定方向に往復移動させる移動機構を有している。したがって、この移動機構を操作することにより、載置板部７０を水平方向に往復移動させることができる。よって、載置板部７０に上記四隅部１２０ａが載置された状態で、回動部材７を連結軸５周りに回動させて載置板部７０の往復方向を変更し、そして、移動機構によって載置板部７０を移動させる。これにより、発電機１２０を、水平方向の任意の方向に向けて、その方向に移動させることができる。尚、上記移動機構の操作は、六角ボルト７８を正逆回転させるだけなので、簡単である。 Furthermore, the mounting plate portion 70 is formed with a shaft hole 70a so that the connecting shaft 5 can move in a predetermined direction in the horizontal direction. And it has a moving mechanism which reciprocates this mounting board part 70 in the said predetermined direction. Therefore, by operating this moving mechanism, the mounting plate portion 70 can be reciprocated in the horizontal direction. Therefore, in the state where the four corners 120a are mounted on the mounting plate portion 70, the revolving direction of the mounting plate portion 70 is changed by rotating the rotating member 7 around the connecting shaft 5, and the moving mechanism. To move the mounting plate portion 70. Thereby, the generator 120 can be moved in that direction toward an arbitrary direction in the horizontal direction. The operation of the moving mechanism is simple because the hexagon bolt 78 is simply rotated forward and reverse.
　さらにまた、上記実施形態によれば、載置板部７０の軸孔７０ａは、長軸方向と載置板部７０の水平方向における移動方向とが一致する長孔である。すると、載置板部７０は、当該移動方向と直交する方向における移動が規制される。このため、載置板部７０を水平方向に移動させる際に、載置板部７０を、上記直交する方向にガタつくことなくスムーズに移動させることができる。 Furthermore, according to the above-described embodiment, the shaft hole 70a of the mounting plate part 70 is a long hole in which the major axis direction coincides with the moving direction of the mounting plate part 70 in the horizontal direction. Then, the movement of the mounting plate portion 70 in the direction orthogonal to the moving direction is restricted. For this reason, when moving the mounting board part 70 to a horizontal direction, the mounting board part 70 can be moved smoothly, without rattling in the said orthogonal direction.
　また、上記実施形態によれば、水平移動機構が連結軸５周りに回動可能なように取り付けられ、且つ、発電機１２０を上下方向に移動させる上下移動機構をさらに備えている。したがって、この上下移動機構を操作することにより、発電機１２０の水平方向における位置調整だけでなく、上下方向における位置調整も可能となる。 In addition, according to the above-described embodiment, the horizontal movement mechanism is attached so as to be rotatable around the connecting shaft 5 and further includes the vertical movement mechanism that moves the generator 120 in the vertical direction. Therefore, by operating this vertical movement mechanism, not only the horizontal position adjustment of the generator 120 but also the vertical position adjustment is possible.
