Therefore, it is possible to attach the sensor for detecting the operating state to the rotating machine without separately forming a part for mounting the sensor for detecting the operating state on the outer surface of the casing of the rotating machine. This produces an excellent effect of being able to.

本発明は、回転機を据付ける基台に回転機の脚がボルト・ナットの固定部材により固定される回転機の作動状態を検出する回転機の作動状態検出装置であって、作動状態検出用のセンサと、作動状態検出用のセンサが取り付けられるセンサ取り付け部材を具備し、回転機の脚とボルト・ナットの固定部材との間に或いは基台とボルト・ナットの固定部材との間にセンサ取り付け部材が介在されるものである。そのため、作動状態検出用のセンサが取り付けられるセンサ取り付け部材を回転機の脚とボルト・ナットの固定部材との間に或いは基台とボルト・ナットの固定部材との間に介在させることにより、回転機のケーシングの外表面に作動状態検出用のセンサを取り付けるための部分を別途形成することなく回転機に作動状態検出用のセンサを取り付けることができる。   The present invention relates to an operating state detecting device for a rotating machine that detects an operating state of a rotating machine in which a leg of the rotating machine is fixed to a base on which the rotating machine is installed by a fixing member of a bolt and a nut. And a sensor mounting member to which a sensor for detecting an operating state is mounted, and the sensor between the leg of the rotating machine and the bolt / nut fixing member or between the base and the bolt / nut fixing member. An attachment member is interposed. For this reason, the sensor mounting member to which the sensor for detecting the operation state is mounted is interposed between the rotating machine leg and the bolt / nut fixing member or between the base and the bolt / nut fixing member. The sensor for detecting the operating state can be attached to the rotating machine without separately forming a part for attaching the sensor for detecting the operating state on the outer surface of the casing of the machine.

上記の技術的手段の具体例を示す実施例を説明する（図１参照）。図１は本発明の実施例である回転機に取り付けた作動状態検出装置の断面図である。回転機１が基台２の上に据付けてある。回転機１は両側の前後に脚を有し、ボルト・ナットの固定部材により基台２に固定されている。図示は回転機１の前脚部を示し、回転機１の前脚３，４がボルト・ナットの固定部材５，６により基台２に固定されている。後脚部についても同様にボルト・ナットの固定部材により基台２に固定されている。   An embodiment showing a specific example of the above technical means will be described (see FIG. 1). FIG. 1 is a cross-sectional view of an operating state detection device attached to a rotating machine according to an embodiment of the present invention. A rotating machine 1 is installed on a base 2. The rotating machine 1 has legs on both sides, and is fixed to the base 2 by bolts and nuts. The figure shows a front leg portion of the rotating machine 1, and the front legs 3 and 4 of the rotating machine 1 are fixed to the base 2 by bolts and nuts fixing members 5 and 6. Similarly, the rear legs are fixed to the base 2 by bolts and nuts.

回転機１の左前脚３と固定部材５のボルトの頭部との間にセンサ取り付け部材７を介在させる。センサ取り付け部材７は基台２と固定部材５のナットとの間に介在させることもできる。また、センサ取り付け部材７は固定部材６側に介在させたり、後脚部の固定部材側に介在させたりすることもできる。   A sensor mounting member 7 is interposed between the left front leg 3 of the rotating machine 1 and the head of the bolt of the fixing member 5. The sensor attachment member 7 can also be interposed between the base 2 and the nut of the fixing member 5. Further, the sensor attachment member 7 can be interposed on the fixing member 6 side, or can be interposed on the fixing member side of the rear leg portion.

センサ取り付け部材７は断面概略Ｌ字状であり、固定部材５のねじ部が貫通しボルトの頭部やナットの外径よりも小径の孔を有する。センサ取り付け部材７に作動状態検出用のセンサ８が取り付けられる。センサ８は回転機１の振動を検出する振動センサであり先端の接触子８ａが回転機１の軸受１ａに当接する。軸受１ａの作動状態を示す振動をセンサ８により検出し、検出信号を出力信号としてケーブル９（ないしは無線式伝送手段）により判定器に送ることで、その判定器において軸受１ａの作動状態を判定する。   The sensor attachment member 7 has a substantially L-shaped cross section, and the screw portion of the fixing member 5 passes through and has a hole having a smaller diameter than the head of the bolt or the outer diameter of the nut. A sensor 8 for detecting an operation state is attached to the sensor attachment member 7. The sensor 8 is a vibration sensor that detects the vibration of the rotating machine 1, and the contact 8 a at the tip contacts the bearing 1 a of the rotating machine 1. The vibration indicating the operation state of the bearing 1a is detected by the sensor 8, and the detection signal is sent as an output signal to the determination device by the cable 9 (or wireless transmission means), whereby the operation state of the bearing 1a is determined by the determination device. .

作動状態検出用のセンサ８が取り付けられるセンサ取り付け部材７を回転機の脚３とボルト・ナットの固定部材５との間に或いは基台２とボルト・ナットの固定部材５との間に介在させることにより、回転機１のケーシングの外表面に作動状態検出用のセンサ８を取り付けるための部分を別途形成することなく回転機１に作動状態検出用のセンサ８を取り付けることができる。   The sensor mounting member 7 to which the sensor 8 for detecting the operation state is mounted is interposed between the leg 3 of the rotating machine and the bolt / nut fixing member 5 or between the base 2 and the bolt / nut fixing member 5. Accordingly, the operating state detection sensor 8 can be attached to the rotating machine 1 without separately forming a portion for attaching the operating state detection sensor 8 to the outer surface of the casing of the rotating machine 1.
