Mobile armrest inspection device of passenger conveyer

Abstract

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).

Description

technical field [0001] The present invention relates to a handrail inspection device of a passenger conveyor that detects whether an abnormality has occurred in a tensile body embedded in a handrail of a passenger conveyor. Background technique [0002] In general, a passenger conveyor is provided with a ring-shaped moving handrail that is held by passengers on the steps to prevent falling, and that walks in conjunction with a guide rail of a handrail. The moving handrail is made of elastic body such as rubber, and the elastic body sometimes loses tension due to temperature changes and long-term use, so that it cannot be tensioned and installed in the guide rail of the railing. In order to prevent this, tensile members such as a plurality of steel wires are embedded in the inside of the moving handrail in line with the extension direction of the moving handrail. [0003] However, when a plurality of tensile bodies are embedded in the moving handrail, each tensile body will ...

Problems solved by technology

[0009] Therefore, although it is conceivable to use an X-ray diagnostic apparatus to diagnose the joint, which is a specific part of the tension body, as in the prior art shown in Patent Document 2, in this case, the joint diagnosis is performed on the captured image. The main body is the operator, and the result of the diagnosis depends on the experience and technology of the operator, so it is difficult to quantitatively evaluate whether there is an abnormality on the joint of the tensile body

[0010] In addition, in the conventional escalator handrail diagnosis device shown in the above-mentioned Patent Document 1, although it is possible to quantitatively inspect the abnormality generated on the metal part of the tension body embedded in the moving handrail, the joint of the tension body The aspect has not been considered, so it is not possible to fully check whether there is any abnormality on the joint
