【Example】

Example 1. 1 is a side view of the step cleaning device, FIG. 2 is a front view of FIG. 1, 8 is a mounting base on which a protruding rod 16 protruding in the center is vertically installed, and 9 is a long piece which is a first piece. Part 9A and second
A support plate 10 having a L-shaped cross section having a short piece portion 9B which is a piece of a screw thread portion 10A which penetrates the short piece portion 9B at one end.
And a vertical bar 12 has a brush 11 at its tip.
Is a cleaning body fixed to the other end of the through bolt 19. In addition, 13 and 14 are provided so as to sandwich the short piece portion 9B, and adjustment nuts for adjusting the height position of the brush 11 with respect to the mounting base 8 are provided. It is an adjustment nut for adjusting the distance between them.

A procedure of using the step cleaning jig having the above structure will be described with reference to FIGS. 3 and 4. First, the portion of the linear skirt guard 3 near the entrance / exit is removed. After that, the hole 4a of the skirt angle 4 and the mounting hole 8a of the mounting base 8 are aligned so that the projecting rod 16 projects toward the step 1 side,
The mount 8 is fixed to the skirt guard 3. At this time, the vertical bar 10 is hung down slightly and temporarily fixed to the short piece portion 9B of the support plate 9 using the adjusting nuts 13 and 14. In addition, the long piece 9A is moved along the protruding rod 16 to adjust the adjusting nuts 17, 1
8 is used to position the brush 11 on the predetermined groove 2A of the color standard body 2. In this state, the vertical bar 10 is pushed down to a position where the brush 11 comes into contact with the bottom surface of the groove 2A as shown in FIG. 4 (a), and the vertical bar 10 is attached to the short piece portion 9B using the adjusting nuts 13 and 14. Fix it.

After the step cleaning jig is attached to the skirt guard 3 on one side as described above, the step cleaning jig is also attached to the skirt guard 3 on the other side. By operating the escalator in this state, the step 1 moves with respect to the brush 11, and as a result, the dirt 7 such as dust is removed.

After cleaning the intermediate groove 2A, as shown in FIG.
As shown in (b), when cleaning the groove 2A on the central portion side of the step 1, the long piece portion 9A is moved along the protruding rod 16 and the vertical rod 10 is pushed down to move the brush 11 to the groove 2A. The groove 2A may be cleaned after the bottom surface is formed.
Further, as shown in FIG. 4C, when cleaning the groove 2A on the skirt guard 3 side, the mounting direction of the support plate 9 with respect to the protruding rod 16 may be changed.

As described above, the step cleaning jig can be attached to the skirt angle 4, and cleaning can be performed while the escalator is operating, so that not only the time required for cleaning can be shortened, but also manpower is not required, and It is possible to carry out safety work. After cleaning, the step cleaning jig can be removed from the skirt angle 4 and the skirt guard 3 can be fixed to the skirt angle 4 to restore the state before cleaning. After that, dirt such as dust collected in the vicinity of the entrance / exit of the escalator can be removed, and the normal operation of the escalator can be performed.
