| 摘要 |
<p>This invention relates to an optical system for automatic geometric-dimensional inspection and control of the wheels of railway vehicles comprising a pair of rails (9, 10) on which a railway vehicle runs, at least one rail (9) of said rail pair (9, 10) including at least one special segment (9') with reduced cross-section, said optical system further comprising at least one optical assembly including an optical device (7) for acquisition of images, a light source (8), a first mirror (11) and a second mirror (12), said optical device (7) and said light source (8) being positioned inside or outside of said wheel pair (9, 10) at respective fixed distances, during the control operation being effected on a wheel, said first mirror (11) relaying the light beam coming from said light source (8) along a direction parallel to the corresponding rail (9) and said second mirror (12) relaying the light beam coming from the first mirror (11) toward said optical device (7), each of said first mirror (11) and second mirror (12) being provided with a movement device that displaces it from the path of the wheels (1) while the orientation of the optical axis is maintained constant. <IMAGE></p> |
