The invention discloses a mobile armrest inspection device of a passenger conveyer. An image is restricted by a detection body (5), so that three sets of joints obliquely arranged with respect to the elongation direction of the inner steel wires buried in the mobile armrest (2) are detected.When the abnormity is continuously detected by an image processor (8) and the variation amount delta P of each light amount is within a predetermined range of a time interval delta t, a joint is determined by a determination mechanism.When the variation amount delta P of each light amount is not within thepredetermined range of the time interval delta t, a joint is not determined by the determination mechanism.When the joint is determined, no abnormality on the joint is judged by an abnormality determination mechanism.When the joint is not determined, an abnormality on the joint is judged by the abnormality determination mechanism.Therefore, whether the abnormality of a tension element is existed or not can be quantitatively and fully detected by the inspection device, including the abnormality of the joint of the inner steel wires buried in the mobile armrest (2). |
