Description

  The present invention relates to a handrail inspection device for a passenger conveyor that inspects for the presence or absence of an abnormality occurring in a tensile body embedded in the handrail of the passenger conveyor.

  In general, the passenger conveyor is provided with an endless handrail that is gripped so that passengers on the steps do not fall down and that engages and runs on a railing rail. This handrail is made of an elastic body such as rubber, and the elastic body loses tension due to temperature change, long-term use, etc., and may not be stretched on the railing guide rail. In order to prevent this, a plurality of tensile bodies such as steel cords are embedded inside the handrail in accordance with the extending direction of the handrail.

  However, even if a plurality of tensile bodies are embedded inside the handrail, these tensile bodies are also subject to metal fatigue, etc. due to movement or overlapping of the tensile bodies over a long period of use. May occur and break. Therefore, since the strength is reduced by the breakage of the tensile body, in order to prevent this, the tensile body inside the handrail is periodically inspected for the presence or absence of an abnormality occurring in the tensile body, and the tensile body is removed. It needs to be repaired and replaced.

  Therefore, as one of the prior arts of a passenger rail handrail inspection device for inspecting a tensile body embedded in such a handrail, an X-ray flaw detector is disposed through a predetermined facing space. The X-ray generator and X-ray irradiator and the X-ray image-receiving unit, ie, the photoreceiver. The main body of the apparatus is supported by a handrail guide from which the handrail is removed. The handrail for the man conveyor that can detect the damage of the tensile body such as the steel cord embedded in the handrail accurately on the spot by arranging the handrail removed from the handrail guide in the space between X-ray flaw detectors are known.

  This X-ray flaw detector includes a shield that shields X-rays from the X-ray irradiator so that the X-rays are not leaked to the outside. An opposing space portion to be inserted is formed. And the shielding body is comprised on the strip, and each piece of a strip is bent according to the shape and position of a handrail.

  On the other hand, the cross section of the handrail has a C-shape, and when the handrail is inserted into the center of the lower end of the upper body of the above-described X-ray flaw detector, the strip of the shield becomes the C-shape of the handrail. According to the shape of the handrail, it is divided into a part that bends to the outside of the handrail and a part that enters the inside of the handrail from the C-shaped opening of the handrail (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-10060

  In the conventional X-ray flaw detector described above, the direction and magnitude of the force received by each piece of the strip varies depending on the shape and position of the handrail, so that a gap is generated between each folded piece of the strip. In particular, since the strip of the shield does not reach the inner curved portion of the handrail, there is a gap between the inner curved portion of the handrail and the shield strip that has entered the handrail. There is a risk of X-rays leaking from these gaps.
