Hereinafter, the coupling extraction device of this embodiment will be described with reference to the drawings. In the figure, the same components as those shown in FIGS. 1 to 3 are denoted by the same reference numerals, and the description thereof is omitted.
FIG. 4 shows the overall structure of the coupling extractor, which is provided with a pair of vertical frames 11 provided with vertical guide grooves 11a on the left and right side surfaces and protruding forward from the upper ends of both vertical frames 11. A carriage 14 comprising a cross beam 12 and having a roller 13 at the lower end, a mounting base 15 supported by the vertical frame 11 of the carriage 14 so as to be movable up and down, and guided up and down by the guide groove 11a, and a mounting base by a handle operation. A hand lift (commercially available, not shown) as an operating device that raises and lowers 15 along the vertical frame 11 in the direction of the arrow in the figure, and a hydraulic pressure fixed on a pallet 15a extending laterally of the mounting base 15. A jack 1, a pair of claw holders 3 attached to the hydraulic jack 1 so as to be openable and closable, and a slide under the pallet of the mounting base 15 in the front-rear direction (left-right direction indicated by arrows in FIG. 4). A rod support 16 that is mounted on the horizontal beam 12 and a chain block 18 as a lifting device supported so as to be slidable in the front-rear (left-right) direction along a long groove (not shown) formed in the cross beam 12. The rod support 16 and the support hanger 19 will be described in order below. The support hanger 19 is movable in the front-rear direction by sliding the block 18 along the cross beam 12.
ロッド支持台１６は図４に示すように取付台1５のパレット１５ａ下面に横梁１２と平行をなしてスライド可能に取付けられ、人手により図４の矢印で示す前後方向にパレット１５ａより引出し或いは押込んで引っ込められるようにしてあり、自由端部には図５及び図６に示すように１ないし複数枚のスペーサ２１を重ね、或いは厚みの異なるスペーサのうち、所要の厚みのスペーサを選択して重ね、その上にＶ形状の受台２２がスペーサ２１と共にロッド支持台１６に図示しないボルトにて取外し可能に取付けられている。 As shown in FIG. 4, the rod support base 16 is slidably attached to the lower surface of the pallet 15a of the mounting base 15 in parallel with the cross beam 12, and is manually pulled out or pushed in from the pallet 15a in the front-rear direction indicated by the arrows in FIG. As shown in FIGS. 5 and 6, one or more spacers 21 are stacked on the free end, or a spacer having a required thickness is selected and stacked from spacers having different thicknesses, A V-shaped pedestal 22 is attached to the rod support 16 together with the spacer 21 so as to be removable by bolts (not shown).
支え吊具１９は図４、図７及び図８に示すように、一対の脚部２４と、両脚部２４の上端を連結する梁２５とで門形をなし、両脚部２４にはそれぞれ外側に支え調整棒２６が着脱可能に取付けられている。支え調整棒２６は一端に受棒２７を直交して取付けてＴ形状をなし、図７に示すように脚部２４の脚端に固定の取付部２８に受棒２７を下向きにした傾斜状態で挿入され、それぞれネジ２３によりネジ止めされて取付部２８に取付けられ、図示しないネジを弛めてスライドさせることにより受棒２７が斜め上下方向に出し入れされ、所望位置でネジ止めして固定されるようになっている。図中、２９はチェーンブロック１８のチェーン１８ａが掛けられるフックである。 As shown in FIGS. 4, 7, and 8, the support hanger 19 forms a gate shape with a pair of legs 24 and a beam 25 that connects the upper ends of the legs 24. A support adjusting rod 26 is detachably attached. The support adjusting rod 26 has a T-shape by attaching a receiving rod 27 orthogonally to one end, and in an inclined state with the receiving rod 27 facing downward on a fixing portion 28 fixed to the leg end of the leg portion 24 as shown in FIG. Inserted, respectively fixed by screws 23 and attached to the mounting portion 28, and loosening and sliding a screw (not shown), the receiving rod 27 is put in and out obliquely in the vertical direction, and is fixed by screwing at a desired position. It is like that. In the figure, reference numeral 29 denotes a hook on which the chain 18a of the chain block 18 is hung.
本装置は以上のように構成され、カップリング交換のため、或いは電動機のオーバーホールのため、回転子に焼きばめされて固定されたカップリングを抜取るときには、図８に示すように固定台３１に電動機６を設置し（電動機６はその自重により固定台３１に固定状態で設置される）、ついで台車１４を所望の向きに押し動かして油圧ジャッキ１７を電動機６のカップリング９に向ける。台車１４を押し動かすのに前後して前記取付板１５のパレット１５ａよりロッド支持台１６を引き出しておく。次にハンドリフトをハンドル操作してパレット上の油圧ジャッキ１を昇降させ、かつ台車１４を向きを変えながら押し動かして、油圧ジャッキ１のラム５と電動機６の回転子７の芯合わせを行う。芯合わせに先立ってパレット１５より引き出されたロッド支持台１６上に目分量で選択し載置した０又は１ないし複数枚のスペーサ２１と共に受台２２を図示しないボルトにて取付け、受台２２にはロッド８を載せ、電動機６の回転子７と油圧ジャッキ１のラム５の間に介在させる（図５参照）。ロッド８が回転子７よりはみ出し、回転子７の周りのカップリング９に当たるときには、ロッド８及び受台２２を取外し、スペーサ２２の数を増減させるか、或いは厚みの異なるスペーサに変え、受台２２及びロッド８の高さを調整する。 This apparatus is configured as described above. When removing the coupling fixed by shrinkage fitting on the rotor for exchanging the coupling or overhauling the electric motor, as shown in FIG. The electric motor 6 is installed (the electric motor 6 is installed in a fixed state on the fixed base 31 by its own weight), and then the carriage 14 is pushed and moved in a desired direction so that the hydraulic jack 17 is directed to the coupling 9 of the electric motor 6. The rod support 16 is pulled out from the pallet 15a of the mounting plate 15 before and after the carriage 14 is pushed and moved. Next, the hydraulic jack 1 on the pallet is moved up and down by operating the hand lift, and the carriage 14 is pushed and moved while changing the direction to align the ram 5 of the hydraulic jack 1 and the rotor 7 of the electric motor 6. Prior to centering, a pedestal 22 is attached with a bolt (not shown) together with zero or one or a plurality of spacers 21 selected and placed on the rod support 16 drawn out from the pallet 15 by a scale. The rod 8 is placed and interposed between the rotor 7 of the electric motor 6 and the ram 5 of the hydraulic jack 1 (see FIG. 5). When the rod 8 protrudes from the rotor 7 and hits the coupling 9 around the rotor 7, the rod 8 and the pedestal 22 are removed, and the number of the spacers 22 is increased or decreased, or the spacers 22 having different thicknesses are replaced. And the height of the rod 8 is adjusted.
電動機６の回転子７と油圧ジャッキ１のラム５との間にロッド８を介在させ、そのまま台車１４を押し動かしてロッド８を回転子７とラム５に押し当てる。この状態でロッド８は回転子７の端面にカップリング９に当たることなく押付けられると共に、ラム５の端面にも押付けられ、芯出しされる（図９参照）。 The rod 8 is interposed between the rotor 7 of the electric motor 6 and the ram 5 of the hydraulic jack 1, and the carriage 14 is pushed and moved as it is to press the rod 8 against the rotor 7 and the ram 5. In this state, the rod 8 is pressed against the end face of the rotor 7 without hitting the coupling 9, and is also pressed against the end face of the ram 5 to be centered (see FIG. 9).
この芯出しに前後して支え吊具１９をチェーンブロック１８の操作により降ろし、両脚部２４よりそれぞれ支え調整棒２６を取外し、受棒２７が下向きとなるように脚部端の取付部２８にそれぞれ差し込んで谷状に取付け、支え調整棒２６を図の矢印方向に移動させ、カップリング９のサイズに合わせて位置調整する（図７）。 Before and after this centering, the support hanger 19 is lowered by operating the chain block 18, the support adjusting rods 26 are removed from the both leg portions 24, and the support rods 27 are directed downward to the attachment portions 28 at the end of the leg portions, respectively. Then, the support adjusting rod 26 is moved in the direction of the arrow in the figure, and the position is adjusted in accordance with the size of the coupling 9 (FIG. 7).
前述の芯出し後、前述するように両鉤爪ホルダー３を閉じて鉤３ａをカップリング９周縁への係止位置に位置させる。その後油圧ジャッキ１の切換弁操作を行ってラム５を突出させるが、ラム５は前記ロッド８を介して電動機６の回転子７に突き当たり、電動機６は固定状態であるため、ラム５の突出に伴い油圧ジャッキ１が台車１４と共に後退し、後退途上で両鉤爪ホルダー３の鉤３ａがカップリング９に係止する。そしてそのままカップリング９を回転子７より抜き取る。カップリング９の抜き取りに伴い、ロッド支持台１６もロッド８と共にスライドして後退する。回転子７より抜き取られたカップリング９は支え調整棒先端の受棒２７で受止められ、支持される（図７）。
以上のようにして電動機６からカップリング９の抜き取りが行われる。
After the above-mentioned centering, both the claw holders 3 are closed as described above, and the collar 3a is positioned at the locking position to the periphery of the coupling 9. Thereafter, the switching valve operation of the hydraulic jack 1 is performed to cause the ram 5 to protrude. The ram 5 hits the rotor 7 of the electric motor 6 through the rod 8 and the electric motor 6 is in a fixed state. Accordingly, the hydraulic jack 1 moves backward together with the carriage 14, and the hooks 3 a of the both claws holder 3 are locked to the coupling 9 on the way back. Then, the coupling 9 is extracted from the rotor 7 as it is. As the coupling 9 is removed, the rod support 16 also slides with the rod 8 and moves backward. The coupling 9 extracted from the rotor 7 is received and supported by the receiving rod 27 at the tip of the support adjusting rod (FIG. 7).
The coupling 9 is extracted from the electric motor 6 as described above.
前記実施形態では、油圧ジャッキ１は台車１４の取付台１５のパレット１５ａ上に固定され、電動機６は固定台３１上に設置しているが、逆に油圧ジャッキ１を固定台上に固定すると共に、電動機６を台車１４のパレット上に設置してもよい。この場合、カップリング９は鉤爪ホルダー３に係止して保持されたまま、電動機６が台車１４と共に油圧ジャッキ１のラム５によって押し動かされ、これに伴いカップリング７が回転子９より離脱する。 In the above embodiment, the hydraulic jack 1 is fixed on the pallet 15a of the mounting base 15 of the carriage 14, and the electric motor 6 is installed on the fixed base 31, but conversely, the hydraulic jack 1 is fixed on the fixed base. The electric motor 6 may be installed on the pallet of the carriage 14. In this case, the electric motor 6 is pushed and moved by the ram 5 of the hydraulic jack 1 together with the carriage 14 while the coupling 9 is locked and held in the claw holder 3, and accordingly the coupling 7 is detached from the rotor 9. .
前期実施形態の台車１４は、所望の向きに押し動かすことで油圧ジャッキ１を電動機６のカップリング９に向けるようにしているが、既知のようにコロを垂直軸線の周りに回転可能に軸支するか、或いは台車をｘ軸とｙ軸方向に移動可能に構成することで、台車を前後左右に移動して油圧ジャッキ１を電動機６のカップリング９に向けるようにすることもできる。 In the carriage 14 of the previous embodiment, the hydraulic jack 1 is directed toward the coupling 9 of the electric motor 6 by being pushed and moved in a desired direction. However, as is known, the roller is supported so as to be rotatable around the vertical axis. Alternatively, by configuring the carriage so as to be movable in the x-axis and y-axis directions, the hydraulic jack 1 can be directed to the coupling 9 of the electric motor 6 by moving the carriage in the front-rear and left-right directions.
前記実施形態では、抜取り装置により電動機６よりカップリング９を抜き取っているが、発電機或いはポンプ、送風機、タービン等の流体機械からカップリングやスプロケット、ブレーキホィール等を抜取る場合も前記と同様にして抜取ることができる。 In the above embodiment, the coupling 9 is extracted from the electric motor 6 by the extraction device. However, the same applies to the case where the coupling, sprocket, brake wheel, etc. are extracted from a fluid machine such as a generator or a pump, a blower or a turbine. Can be removed.
