Moreover, L-shaped interference prevention brackets 15 are provided on both sides of the upper integrated sensor 6 out of the pair of integrated sensors 6.

A work procedure label 9 a shown in FIG. 7 is affixed to the wiring box 9.
In addition, a caution label 9b shown in FIG. 8 is affixed to each skirt guard 1, 2 and 3.
This work procedure label 9a is a simple work instruction, which describes a material number indicating details, and also plays a role of leading to necessary materials when it is desired to know the detailed contents.

Next, a procedure for attaching the skirt guards 1, 2, and 3 to the lower angle 12 and the upper angle 16 will be described.
First, the fixed clip 17 of the lower skirt guard 1 is pushed into the lower angle 12, and the lower skirt guard 1 is fixed to the upper angle 16.
Next, the middle skirt guard 2 is attached to the lower angle 12 and the upper angle 16 in the same manner as the lower skirt guard 1. When the middle skirt guard 2 is fixed, the integrated sensor 6 disposed on the upper side of the handrail 13 on the return path is mounted on the skirt guard 2 in advance.

  After that, the separate sensor 7 attached to the separate fixing part 8 is inserted into the inside 31 of the housing from the empty space next to the middle skirt guard 2, and the front part of the separate sensor 7 with the lens 34 is optically illuminated. After fine adjustment within the detection range of the shaft and inserting it into the window (not shown) of the middle skirt guard 2, the separate fixing component 8 is fixed to the lower angle 12 using the bolt 32.

In the middle skirt guard 2, a separate sensor 7 (see FIG. 3) is arranged below the handrail 13 on the return path, and when the separate sensor 7 is attached to the middle skirt guard 2 in advance, the middle skirt guard When 2 is attached to the lower angle 12, it interferes with the handrail 13 on the return path.
However, after attaching the middle skirt guard 2 to the lower angle 12 and the upper angle 16 in this way, the separate sensor 7 is attached via the separate fixing part 8 from the space before the adjacent upper skirt guard 3 is attached. Such inconvenience does not occur.

Next, the wiring box 9 is fixed to the upper angle 16 using the bolts 33 through the metal fitting 35, and the electric cable in the wiring box 9 and each integrated sensor 6 and separate sensor 7 are connected to the sensor cable 10. Use for electrical connection.
Finally, in the same manner as the lower skirt guard 1, the upper skirt guard 3 is pushed into the lower angle 12 and the upper skirt guard 3 is fixed to the upper angle 16.

Next, a procedure for removing the skirt guards 1, 2 and 3 from the lower angle 12 and the upper angle 16 will be described. This order of removal is the reverse of the order of installation.
First, the upper skirt guard 3 is moved upward and removed from the lower angle 12 and the upper angle 16.
Next, after loosening the bolt 32, the separate fixing component 8 is retracted from the window of the middle skirt guard 2 to the position where it is extracted from the front surface of the separate sensor 7. In addition, the tip of the sensor cable 10 is removed from the electrical equipment in the wiring box 9.
Thereafter, the middle skirt guard 2 is moved upward and removed from the lower angle 12 and the upper angle 16.
Finally, the lower skirt guard 1 is moved upward and removed from the lower angle 12 and the upper angle 16.

By the way, if the procedure for removing the skirt guards 1, 2 and 3 from the lower angle 12 and the upper angle 16 is wrong, and the middle skirt guard 2 is to be removed before removing the upper skirt guard 3, the window of the middle skirt guard 2 It is assumed that the separate sensor 7 having the front part inserted into the part is damaged.
On the other hand, the lower bracket 4 of the middle skirt guard 2 interferes with the upper bracket 5 of the upper skirt guard 3, thereby preventing the middle skirt guard 2 from moving upward.
As described above, in the escalator of this embodiment, the skirt guards 1, 2 and 3 are restricted so that they cannot be removed by an incorrect procedure, and the correct procedure is guided to prevent damage to the equipment due to an incorrect removal order. Can do.

In this embodiment, the work procedure label 9 a is attached to the wiring box 9, and the warning label 9 b is attached to the upper angle 16 corresponding to each skirt guard 1, 2, 3.
Therefore, when the operator removes the skirt guards 1, 2 and 3, the worker can proceed with the work by visually recognizing the alert label 9b and the work procedure label 9a.

The work flow required for the operator who removes the skirt guards 1, 2 and 3 is as shown in FIG. 9, but when the inner deck 18 is removed, a warning is issued indicating that there is a procedure for removing the skirt guards 1, 2 and 3. The operator can confirm the label 9b. Therefore, it is not necessary to be aware of the majority of escalators that have no restrictions on the procedure for removal, and if there are restrictions, the restrictions can be noticed without fail.
Further, the operator can know from the markings written in advance whether each skirt guard 1, 2, 3 is the upper, middle or lower skirt guard 1, 2, 3.
Then, after the upper skirt guard 3 is removed, the worker can visually recognize the work procedure label 9a attached to the wiring box 9 and proceed with the work.

  According to the escalator according to this embodiment, the skirt guards 1, 2, 3 having restrictions on the movement order in the vertical direction between the adjacent skirt guards 1, 2, 3 have one skirt guard 1, 2, 3 A lower bracket 4 is provided at the end, and the other skirt guard 1, 2, 3 interferes with the lower bracket 4 when one skirt guard 1, 2, 3 moves in the vertical direction. An upper bracket 5 that prevents vertical movement is provided.

  Therefore, the skirt guards 1, 2, and 3 are prevented from being removed by an erroneous procedure, and the separate sensor 7 can be prevented from being damaged by the erroneous procedure.

Further, as shown in FIG. 10, even when the skirt guard 14 of the escalator already installed in the building is replaced to provide the function of guiding and restricting the attachment / detachment procedure, only the skirt guard 14 on which the sensors 6 and 7 are mounted is provided. For example, the existing two guard guards 14 may be subdivided into three, and the other skirt guards 14 need not be changed.
Even if there are multiple skirt guard-embedded devices that may interfere with the devices near the back of the skirt guards 1, 2, and 3, the number of skirt guards to be replaced is minimized by subdividing only the skirt guard. Can be changed.

  In this way, even when it is desired to provide the escalator skirt guard 14 of the existing escalator with the function of guiding the attachment / detachment procedure and the function of restriction, it is not necessary to replace all the existing skirt guards. By providing the upper bracket 5, it is possible to cope with this, and by minimizing the number of replacement skirt guards, the work on site can be reduced and the work time can be shortened.

Further, the separate sensor 7 on the back surface of the middle scard guard 2 uses the space of the adjacent upper skirt guard 3 (not attached) to fix the separate fixing component 8 to the lower angle 12 with the bolt 32, Since it is disposed on the back surface, the separate sensor 7 can be attached and detached smoothly.
The sensor cable 10 derived from the sensors 6 and 7 is connected to the electrical equipment in the wiring box 9, but the wiring box 9 and the connection part are in the space of the upper skirt guard 3. And the attachment and removal work of the sensor cable 10 of the separate sensor 7 can be performed smoothly, and the confirmation can be easily performed.

Further, an interference preventing bracket 15 is provided in the vicinity of the integrated sensor 6 to prevent the integrated sensor 6 from interfering with peripheral devices (not shown) when the middle scard guard 2 moves upward. Yes.
Accordingly, when the operator moves the middle skirt guard 2 in the upward direction, there is a possibility of interference with the upper angle 16, but it is possible to prevent damage to the integrated sensor 6 due to interference with the interference prevention bracket 15. it can.
