本発明は複数の回転機械が互いに隣接して据付
けられる回転機械の据付装置に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating machine installation device in which a plurality of rotating machines are installed adjacent to each other.
従来のこの種の回転機械の据付装置は回転機械
のケーシングの取付フランジに、締結用のボルト
サイズに合致した通常精度のボルト孔を穿設し、
同ボルト孔に貫挿したボルトを介して回転機械を
基礎または台盤に螺着、固定していた。 Conventional installation equipment for this type of rotating machinery involves drilling bolt holes with normal accuracy that match the bolt size for fastening into the mounting flange of the casing of the rotating machine.
The rotating machine was screwed and fixed to the foundation or base plate through the bolt inserted into the same bolt hole.
この場合、回転機械が基礎または台盤に固定さ
れているので、複数の回転機械のうち１台が事故
を起すと、回転を伴なう衡撃力がそのまま基礎、
または台盤に伝わり、隣接する回転機械にもその
衝撃力が伝播してしまうという欠点があつた。 In this case, since the rotating machines are fixed to the foundation or platform, if one of the multiple rotating machines causes an accident, the impact force accompanying the rotation will be directly transferred to the foundation or to the base.
Another drawback was that the impact force was transmitted to the base plate and was also transmitted to adjacent rotating machines.
第１図は回転機械に事故が発生した場合の衝撃
力が、隣接する回転機械に伝わる代表的な例を示
し、基礎１または台盤上に複数の回転機械２Ａ，
２Ｂ，２Ｃ…が密接に並べて据付けられている。 Figure 1 shows a typical example in which the impact force when an accident occurs in a rotating machine is transmitted to adjacent rotating machines.
2B, 2C... are installed closely side by side.

する。 If the rotating machine 2A causes an accident, the rotating machine 2A will vibrate as shown by the dotted line due to the impact force at that time, and the foundation 1 or the base will be deformed as shown by the dotted line due to this vibration. , the vibrations propagate to the adjacent rotating machines 2B and 2C installed above.

案されているが、これらは事故時の衝撃力がその
まま基礎または台盤に伝わるという致命的な欠陥
を有し、所期の目的を達成することはできなかつ
た。 In order to prevent this phenomenon, installation devices that attach the rotating machine closely to the foundation or platform, increase the rigidity of the foundation or platform, or change the natural frequency of the rotating machine's casing are used. However, these had the fatal flaw that the impact force at the time of the accident was directly transmitted to the foundation or base, and the intended purpose could not be achieved.
またこのように回転機械を直接、台盤上に設置
することなく、防振ゴム等の緩衝材を介して設置
する回転機械の据付装置が、例えば実開昭52−
138407号公報において提案されている。 In addition, there is an installation device for a rotating machine that does not directly install the rotating machine on a base plate, but uses a cushioning material such as anti-vibration rubber, for example.
This is proposed in Publication No. 138407.
しかしながら竪型の高速回転機械は回転性能

らず、前記従来例の如き緩衝材上への直置き構造
では緩衝材自体が変形し、初期据付レベルが所定
のレベルに保持されない。 However, although vertical high-speed rotating machines require a high-performance installation level due to their rotational performance, the structure of placing them directly on the cushioning material as in the conventional example above deforms the cushioning material itself, and the initial installation level is not maintained at a given level.
また仮に初期据付レベルが所定のレベルに設定
されたとしても、緩衝材の経時劣化（変形）によ
つて据付レベルが変化し、回転機械の回転性能に
支障を招来するという問題点があつた。 Further, even if the initial installation level is set to a predetermined level, there is a problem in that the installation level changes due to deterioration (deformation) of the cushioning material over time, causing problems in the rotational performance of the rotating machine.
本発明はこのような問題点を解決するために提

械の据付装置に係るものである。 The present invention has been proposed to solve these problems, and is a rotating machine installation device in which a plurality of rotating machines are installed adjacent to each other on a foundation or platform. The casing of the machine is attached to the foundation or platform via a vertical fastening member between the fastening member and the casing, so that the casing does not interfere with linear movement in a horizontal plane or rotational movement in a horizontal plane with the adjacent rotating machine. The casing is fastened so that there is a gap that may occur within the range where the casing does not move, and a buffer member is disposed opposite the casing to cause the fastening member to stop the movement of the casing within the gap. This relates to machine installation equipment.

Ｃへの振動の伝播をかなり抑制することができ
る。 In the rotating machine installation device shown in FIG. 1, the deformation mode of the rotating machine 2A that caused the accident is linear motion as shown by the dotted line in FIG. 2 or the arrow in FIG. 3, or rotational motion in a horizontal plane. , the adjacent rotating machines 2B, 2
The propagation of vibration to C can be considerably suppressed.
実際にはこのような直線運動や水平面内回転運

第１図に示すように回転機械ケーシングのロツキ
ングモードを併発する。 In reality, it is extremely difficult to maintain only such linear motion or rotational motion mode in the horizontal plane.
As shown in Figure 1, a locking mode of the rotating machine casing also occurs.

ことができる。 However, in the present invention, as described above, the casing of the rotating machine is fastened to the foundation or the base plate via the vertical fastening member, and a gap is provided between the fastening member and the casing, so that the casing is connected to the horizontal surface. Since the structure is such that internal movement or rotational movement in the horizontal plane can occur within a range that does not interfere with the adjacent rotating machine, locking mode can be activated by consuming a part of the energy generated when an accident occurs. The response can be made smaller.

大を防止しうるものである。 Moreover, in the present invention, a buffer is provided to the fastening member to stop the movement of the casing in a gap formed between the vertical fastening member and the casing that allows movement in the horizontal plane and rotational movement in the horizontal plane of the rotating machine. The member was arranged opposite to the casing, and the casing that caused linear movement in the horizontal plane collided with the buffer member, deforming the buffer member and stopping, so the movement of the casing was compared. This will allow the vehicle to come to a quiet stop and prevent the spread of the accident.

うなことがない。 Furthermore, according to the present invention, the rotary machine is firmly fastened directly to the foundation or the bed plate via the vertical clamping member, and as in the conventional installation device, the rotary machine is connected to the cushioning material on the foundation or the bed plate. When placed directly on top of a rotating machine, the initial installation level may not be maintained at the specified level due to deformation of the cushioning material, or the installation level of the rotating machine may change due to deterioration of the cushioning material over time, causing rotation. There is no problem in performance.
