Can be gripped. The moving handrail 12 is driven by a terminal gear 15 for driving the moving handrail. The terminal gear 15 is configured to be synchronously rotatable by a sprocket 14 and a chain 16 that are rotated by a driving device (not shown). Thereby, the moving handrail 12 and the step are driven in the same direction at the same speed.

  With respect to such an escalator, the mobile handrail deterioration diagnosis apparatus 1 according to the present embodiment is attached to the frame 13 and measures for deterioration diagnosis of the mobile handrail 12 on the return path side of the mobile handrail 12 moving in the frame 13. Is supposed to do.

  1 and 2 are views showing a configuration of an embodiment of a deterioration diagnosis apparatus for a moving handrail according to the present invention. FIG. 1 is a front view and FIG. 2 is a side view.

  As shown in FIGS. 1 and 2, the deterioration diagnosis device 1 for a moving handrail according to this embodiment includes a fixing portion 7, a screw rod 8 a that is screwed into a screw portion formed on the fixing portion 7, and the screw rod. It has a fixed handle 8 including a pressing portion 8b provided at the lower end of 8a and a handle portion 8c provided at the upper end of the screw rod 8a. The embodiment can be attached to any position of the frame 13 by rotating the fixed handle 8 and sandwiching the frame 13 of the passenger conveyor by the bottom surface portion 7a of the fixed portion 7 and the pressing portion 8b of the fixed handle 8. It has become.

  As shown in FIG. 1, an upper and lower rail 9 whose longitudinal direction is vertically arranged is connected to the fixing portion 7. The relative position of the fixed portion 7 and the upper and lower rails 9 can be changed vertically along the rail portion 9a provided in front of the upper and lower rails 9, and the fixed handle 10 is tightened at an arbitrary position of the rail portion 9a to move up and down. The position of the fixing portion 7 can be fixed with respect to the rail 9. Further, as shown in FIG. 2, the upper and lower rails 9 are also provided with rail portions 9 b on the surface facing the moving handrail 12. The left and right rails 11 are movably provided in the vertical direction along the rail portion 9b on the rail portion 9b provided on the opposite surface of the moving handrail 12. The left and right rails 11 are arranged so that the longitudinal direction thereof is perpendicular to the moving handrail 12 and also perpendicular to the longitudinal direction of the upper and lower rails. Note that the term "orthogonal" as used herein means that the highest possible functionality can be obtained in the strict sense of orthogonal form in consideration of the followability of the camera mechanism to the moving handrail 12 described later. In consideration of the complexity of attaching to the form, the work efficiency and the substantial orthogonality within the range in which the functionality is not lost are also included here.

  As shown in FIGS. 1 and 2, the left and right rail 11 is movable in the left and right direction along the rail portion 11 a, and the camera 5 with an illuminating unit for photographing the canvas surface 12 a of the moving handrail 12 has the connecting portion 4. Is attached through. The camera with an illumination unit 5 is provided with an objective lens 5a for capturing an object to be photographed at the center, and an illumination unit having a light source arranged around the objective lens 5a in an annular shape around the objective lens 5a, that is, a plurality of LEDs 5b. Is included.

  As shown in FIG. 1, the connecting portion 4 is provided with moving handrail support rollers 2 a and 2 b so as to be positioned at both left and right ends of the moving handrail 12. For example, the moving handrail support roller 2 a provided on one end side of the moving handrail 12 is fixed to the connecting portion 4, but the moving handrail support roller 2 b provided on the other end side moves the moving handrail support roller 2 a to the moving handrail 12. It attaches to the connection part 4 via the press spring which presses to the one end side. Accordingly, the movable handrail 12 is sandwiched from the left and right ends by the movable handrail support roller 2a and the movable handrail support roller 2b. Further, as shown in FIG. 2, the surface of the connecting portion 4 opposite to the predetermined portion where the camera 5 with the illumination unit is provided comes into contact with the canvas surface 12 a of the moving handrail 12 and rotates on the canvas surface 12 a. A vertical follower roller 3 is attached. The camera angle fixing handle 6 adjusts the angle of the camera 5 with an illumination unit capable of appropriately photographing the canvas surface 12a of the moving handrail 12 to be measured, and fixes the camera 5 to the connecting unit 4. .

  In this embodiment, the camera mechanism is constituted by the movable handrail support rollers 2 a and 2 b, the up and down following roller 3, the connecting portion 4, the camera 5 with the illumination portion, and the camera shooting angle fixed handle 6. In the present embodiment, the camera hand following means is constituted by the movable handrail support rollers 2 a and 2 b and the upper and lower follow rollers 3.

  When performing the diagnosis of the moving handrail 12 by the moving handrail deterioration diagnosis device 1 according to the present embodiment configured as described above, first, the fixed portion 7 and the fixed handle 8 are placed at an arbitrary position of the frame 13 of the passenger conveyor. A moving handrail deterioration diagnosis apparatus 1 according to this embodiment is attached. If necessary, adjustment is performed in consideration of the movable range in the vertical direction, and the upper and lower rails 9 are fixed to the fixed portion 7 by the fixed handle 10. If there is no particular need for adjustment, the fixing portion 7 may be fixed at the upper end of the upper and lower rails 9. Subsequently, the left and right ends of the movable handrail 12 are sandwiched by the movable handrail support rollers 2 a and 2 b, and finally the angle of the camera 5 with the illumination unit is adjusted by the camera photographing angle fixing handle 6.

  In this way, the deterioration diagnosis device 1 of the moving handrail according to the present embodiment attached to the frame 13 can hold the left and right rails 11 to be freely movable on the upper and lower rails 9. Further, the camera mechanism can be held movably on the left and right rails 11. Therefore, when photographing the canvas surface 12a of the moving handrail 12 while the escalator is operated and the moving handrail 12 fluctuates in the left-right direction, the moving handrail support rollers 2a and 2b follow the fluctuation of the moving handrail 12. The entire camera mechanism is moved left and right by the left and right rails 11. Further, the camera mechanism displaces the left and right rails 11 along the upper and lower rails 9 until the vertical follower roller 3 comes into contact with the canvas surface 12a of the moving handrail 12 by its own weight. When the moving handrail 12 fluctuates in the upward direction, the up-and-down following roller 3 follows up and displaces the left and right rails 11 along the upper and lower rails 9 and vice versa. The vertical tracking roller 3 also follows the moving handrail 12 due to the weight of the camera mechanism, and the left and right rails 11 are displaced downward along the vertical rails 9. By such an operation, the canvas surface 12a as an object to be photographed by the camera mechanism and the moving handrail 12 can follow the relative position of the moving handrail 12 so that the relative position does not change regardless of the vertical, left and right directions.

  Thus, when fixing the deterioration diagnosis device 1 of the moving handrail according to the present embodiment to the escalator, the operator only needs to pay attention to attaching the fixing portion 7, and the left-right direction of the camera 5 with the illumination portion. The vertical direction is uniquely determined with the installation.

  The installation of the present embodiment does not require any special adjustment, and in the present embodiment, the camera 5 follows the moving handrail 12 in the vertical and horizontal directions as the moving handrail 12 moves. Thus, since the canvas surface 12a of the moving handrail 12 can be photographed, the imaging range is always constant, and the normal quality moving handrail 12 and the deteriorated moving handrail 12 can be compared on the same scale. . Thereby, it is possible to easily diagnose the deterioration state of the moving handrail 12.

  In addition, in the present embodiment, even when severe deterioration such as swelling or cracking occurs in the moving handrail 12 by the moving handrail support rollers 2a and 2b and the vertical tracking roller 3, it is possible to always shoot in a certain range. The imaging range is always constant regardless of the state, and the normal-quality moving handrail 12 and the deteriorated moving handrail 12 can be compared on the same scale.

  Further, in the present embodiment, the camera 5 has an illumination part in which a plurality of LEDs 5b are arranged in an annular shape around the objective lens 5a around the objective lens 5a, and the longitudinal direction of the upper and lower rails 9 is the illumination part. It is arranged parallel to the central axis, and the longitudinal direction of the left and right rails 11 is arranged orthogonal to the central axis of the illumination unit, and the distance between the illumination unit of the camera 5 and the moving handrail 1 as the diagnostic object is always set. Since imaging is performed at a constant level, it is possible to suppress uneven brightness of the diagnostic object. As a result, highly accurate deterioration diagnosis can be performed.

  Further, in the present embodiment, it is possible to take a mechanism for photographing the canvas surface 12a of the moving handrail 12 with the camera 5 and diagnosing the deterioration state of the canvas surface 12a for each image. In order to perform such a diagnosis, the canvas surface 12a fits within a predetermined size within the field angle range of the camera 5, and the center of the canvas surface 12a of the moving handrail 12 coincides with the center of the image. If 5 is not installed, it cannot be diagnosed correctly. However, since the moving handrail 12 moves slightly up and down and left and right while the passenger conveyor is operating, it is basically difficult to keep the image range in a predetermined size. On the other hand, this embodiment has a camera installation structure including guide means including the upper and lower rails 9 and 11 so that the positional relationship between the objective lens 5a of the camera 5 and the moving handrail 12 is always constant. When the camera 5 is attached to a narrow space within the truss of the passenger conveyor, it is possible to photograph the canvas surface 12a of the moving handrail 12 without the camera 5 installed being shaken by anyone.

  Accordingly, the present embodiment can improve the accuracy of the deterioration diagnosis of the moving handrail 12 while suppressing the variation in the diagnosis result of the moving handrail 12. Thereby, this embodiment can grasp | ascertain reliably the replacement time of the deteriorated moving handrail 12. FIG.

  In addition, about the imaging | photography data image | photographed with the camera 5 of this embodiment, the form which accumulate | stores in the said diagnostic apparatus 1 of the said handrail, and verifies and diagnoses the stored imaging | photography data later may be sufficient. The mobile handrail diagnosis apparatus 1 according to the above may be connected to a device such as a personal computer, and the photographing data may be stored in the personal computer or the like, and the stored photographing data may be verified and diagnosed later. Furthermore, the present embodiment may be connected to an image display device such as a display, and diagnosis work may be performed while photographing, or the present embodiment may be connected to a device such as a personal computer to perform diagnosis using image analysis or the like. Etc. can also be performed.

  Moreover, although the escalator was cited as the passenger conveyor on which the present embodiment is installed, the present invention is not limited to being installed on the escalator in this way, and is installed on another passenger conveyor such as a moving sidewalk to move a handrail. You may make it perform 12 diagnoses.
