Description

  The present invention relates to a passenger conveyor maintenance method suitable for maintaining a handrail guide for guiding a handrail provided in a passenger conveyor.

  FIG. 6 is a side view showing a configuration of an escalator cited as an example of a passenger conveyor.

  As shown in FIG. 6, a passenger conveyor, for example, an escalator, includes a plurality of steps 1 connected endlessly and circulated, a balustrade 2 erected on the side of these steps 1, and a peripheral portion of the balustrade 2 An endless handrail 4 provided on the handrail, a handrail guide 3 for guiding the handrail 4, a length adjusting device 5 for adjusting the extra length of the handrail 4 by applying tension to the handrail 4, A handrail drive device 6 that circulates and moves the handrail 4 together with the steps 1 is provided. The handrail drive device 6 includes a plurality of rollers 6a that are in sliding contact with the inner side surface of the handrail 4 and a plurality of rollers 6b that are in sliding contact with the outer side surface of the handrail 4, and these rollers 6a and 6b rotate. As a result, the handrail 4 is circulated and moved in the same speed and in the same direction as the movement of the step 1. Further, an upper entrance 7 and a lower entrance 8 are installed in front and rear of the passenger conveyor, respectively.

  When the handrail 4 of the escalator described above is guided by the handrail guide 3, sliding friction is generated between the handrail guide 3 and the handrail guide 3. For this reason, if the escalator is used for a long period of time, the handrail guide 3 will be worn by this sliding friction, so maintenance such as inspection of the amount of wear of the handrail guide 3, replacement, and cleaning of wear powder is periodically performed. is doing.

  Such an escalator is conventionally performed by removing the handrail 4 from the handrail guide 3, but requires a great deal of labor when removing the handrail 4 from the handrail guide 3. Therefore, as one of the prior arts of a method for easily removing the handrail 4 from the handrail guide 3 and performing maintenance of the passenger conveyor, a passenger conveyor handrail detaching method shown in Patent Document 1 is known.

  FIG. 7 is a diagram for explaining a conventional method for detaching a handrail of a passenger conveyor.

  The passenger rail handrail detachment method disclosed in Patent Document 1 lifts a part of the handrail 4 fitted to the balustrade upper part 7A shown in FIG. Remove from the rail guide 3. Then, the handrail 4 is lowered along with the step 1 by driving the handrail driving device 6.
