The shielding member 20 was provided. This shields the X-ray 70 from leaking from the notch 19. Therefore, the user can safely approach the X-ray inspection apparatus 9 even during the operation of the X-ray inspection apparatus 9, and can perform the diagnosis work safely.

Further, a blower 15 for cooling the X-ray tube 13 with air was provided. Thus, it is not necessary to interrupt the diagnostic work every predetermined time to cool the X-ray tube 13, and the X-ray inspection apparatus 9 can be used continuously for 60 minutes or more. Therefore, the moving cable 6 is not intermittently diagnosed.
Diagnostic work can be performed smoothly.

Further, the moving cable 6 is supported from below,
Rollers 16, 16a are provided for guiding without bending.
Thereby, the distance between the lower surface of the moving cable 6 and the X-ray tube 13 is always kept constant, so that the visible image of the wire bundle 10 can be prevented from being partially blurred. Therefore, the operator can easily check whether or not the wire bundle 10 is broken from the image of the wire bundle 10.

[0082]

According to the first aspect of the present invention, the X-ray inspection apparatus is located on one surface side of the moving cable, and the X-ray generator irradiates the moving cable with X-rays. Is located on the other side of the opposite side, facing the X-ray generation unit with the moving cable in between, and an X-ray image receiving unit for converting X-rays transmitted through the moving cable into a visible image; And a supporting means detachably attached to a predetermined position and supporting the X-ray inspection apparatus. Thus, the wire bundle can be inspected without removing the moving cable, and the moving cable can be easily diagnosed. Therefore, it is possible to easily determine whether or not to replace the moving cable, and there is no waste of replacing a moving cable that does not hinder the operation of the sloping elevator with a new moving cable. It can be used efficiently.

According to the second aspect of the present invention, the predetermined position where the supporting means is detachably attached is a frame provided with a guide rail for guiding the elevator car up and down. Thereby, the X-ray inspection apparatus can be easily attached.

According to the third aspect of the present invention, a visible image is transmitted to a position separated by a predetermined distance from the X-ray inspection apparatus, and the transmitted visible image is displayed at a position separated by a predetermined distance. Means were provided. Thereby, the wire bundle can be diagnosed at a position separated from the X-ray inspection apparatus by a predetermined distance. Therefore, diagnosis of the moving cable can be performed safely.

In the invention according to claim 4, air cooling means for cooling the X-ray tube provided in the X-ray generation unit with air is provided. This makes it difficult for the X-ray generation unit to overheat, and it is possible to use the X-ray inspection apparatus continuously for 60 minutes or more without the need for intermittently turning off the X-ray generation unit and cooling. Therefore, the diagnostic work can be performed smoothly without interruption of the diagnostic work for cooling the X-ray generation unit.

In the invention according to claim 5, a guide body is provided between the X-ray generation unit and the X-ray image receiving unit for guiding the movable cable so as not to bend. Thereby, the distance between the lower surface of the moving cable and the X-ray tube is always kept constant, so that the visible image of the wire bundle can be prevented from being partially blurred. Therefore, the operator can easily diagnose whether or not the wire bundle is broken from the image of the wire bundle.
