A feature of this embodiment is that the escalator handrail driving device 2 is provided with a pressure roller cleaning device 3 (hereinafter referred to as a pressure roller cleaning device) of the escalator handrail driving device for cleaning the pressure roller. It is that.

The pressure roller cleaning device 3 comprises a holding base 10 fixed to the substrate 34 and a cleaning member 12 fixed to the holding base 10. As shown in FIG. 2, the holding table 10 is attached to the substrate 34 together with the leaf spring 42 on the outer side thereof.

As shown in FIG. 3, the holding table 10 includes a substrate 3
Fixed part 10a attached to the No. 4 and fixed part 10a
And a holding portion 10c extending from the connecting portion 10b to the lower side of the pressure roller 38. The holding base 10 can be formed by integrally molding a plate-shaped member, for example.

The cleaning member 12, in this embodiment, is
It is fixed to the holding portion 10c of the holding table 10 via an elastic member 14 such as a spring. Therefore, the cleaning member 12 can be brought into contact with the pressure roller 38 by the urging force of the elastic member 14. As a result, as described later,
When the pressure roller 38 is soiled due to adhesion of dust or the like, the rotated pressure roller 38 can be cleaned.

In the present embodiment, since the cleaning member 12 can be brought into contact with the pressure roller 38 by the elastic member 14, the cleaning member 12 is, for example, cloth, sponge or the like that has some elasticity. It can be used as the member 12. When a cloth, a sponge, or the like is used as the cleaning member 12, it is suitable because it can be impregnated with cleaning oil or the like.

Further, in this embodiment, two cleaning members 12 are provided for one pressure roller 38. When two cleaning members are provided in this manner, it is also preferable that one cleaning member 12 is impregnated with cleaning oil and the other cleaning member 12 is a wiping member for cleaning oil that adheres to the pressure roller 38. is there.

Next, the operation of the pressure roller cleaning device 3 of the escalator handrail drive device will be described.

When power from a drive unit (not shown) is transmitted to the drive roller 36 and the drive roller rotates, the rotational drive force is transmitted to the moving handrail 32. As a result, the moving handrail 32 moves, and the pressure roller 38 rotates as the moving handrail 32 moves. As described above, since the cleaning member 12 of the pressure roller cleaning device 3 is in contact with the pressure roller 38 by the elastic member 14, the rotating pressure roller 38 can be cleaned.

The pressure roller cleaning device 3 may be attached and used during normal operation, or may be attached and used only during maintenance.
