Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a tail clearance measuring device advantageous in achieving a reduction of a burden on an operator while being capable of achieving improvement of measurement efficiency.SOLUTION: A tail clearance measuring device 30 is configured so as to include: a camera section 42; a detection light projection section 44; and a computer 34. The tail clearance measuring device 30 derives a tail clearance Tc on the basis of image information of a segment end surface region Se including first detection light L1 imaged by the camera section 42 while projecting the linear first detection light L1 intersecting with a first circular arc portion C1 where the segment end surface region Se extending in a radial direction of a segment 20 on an end surface 2006 of the segment 20 and an inner peripheral surface 2004 of the segment 20 intersect with each other and extending on the end surface 2006 to the segment end surface region Se by the detection light projection section 44.SELECTED DRAWING: Figure 5
【課題】測定効率の向上を図れると共に、作業員の負担の軽減を図る上で有利なテールクリアランス測定装置を提供する。【解決手段】テールクリアランス測定装置30は、カメラ部42と、検出光投射部44と、コンピュータ34とを含んで構成されている。検出光投射部44によりセグメント20の端面2006上でセグメント20の半径方向を延在するセグメント端面領域Seとセグメント20の内周面2004とが交わる第1の円弧部分C1に交差し端面2006上を延在する線状の第1の検出光L1をセグメント端面領域Seに投射すると共に、カメラ部42によって撮像された第1の検出光L1を含むセグメント端面領域Seの画像情報に基づいてテールクリアランスTcを導出する。【選択図】図5 |
