Embodiment 2
Then, the escalator 10 of embodiment 2 is illustrated based on Fig. 6.Present embodiment exists with the difference of embodiment 1
In the number of worm gear 72, in the present embodiment, 2 worm gears 72 are set.
As shown in Embodiment 1, when worm gear 72 is 1, exist because floor height, i.e. the operating range of step 30 is long
Escalator 10 in, the hypodynamic situation of driving of handrail 38.Therefore, set gradually along the travel direction of handrail 38
2 worm gears 72, rotate it respectively by band motor 76, obtain stronger driving force to travel handrail 38.
Thus, even if the escalator 10 of floor height, can also make handrail 38 with the same speed of step 30 and platform
The synchronous traveling of rank 30.
In present embodiment, although there is provided 2 worm gears 72, but it can also be replaced, the worm gear of more than 3 is set
72, so as to obtain stronger driving force.
Variation
Although in the above-described embodiment, there is provided 2 pressing roller 74, can also replace it, set more than 2
Pressing roller 74, it is stronger and equably handrail 38 is pressed on worm gear 72.
In addition, in the above-described embodiment, test section 82 is set to the rotating speed using light sensors drive sprocket 24,
But it can also be replaced, limit switch etc. is detected.Alternatively, it is also possible to using driving current from inverter circuit 68 etc. come
The rotary speed of main motor 20 is detected, so as to control band motor 76.
In addition, in the above-described embodiment, the rack 92 set in the inside of handrail 38 is vulcanie, but also may be used
To replace it, only convex portion 96 is to be made of metal.
In above-mentioned embodiment, the situation suitable for escalator 10 is illustrated, but it can also be replaced, it is adaptable to
Walkways.
Although a described above embodiment of the present utility model, the embodiment is only for illustrating this
The content of utility model, and scope of the present utility model is not limited to that.These can also be implemented by other various ways
Novel embodiment.In the range of without departing from objective of the present utility model, the omission of various modes can be carried out to it, is put
Change, change.These embodiments and its deformation are contained in scope of the present utility model and objective, and being equally also contained in right will
Ask in the utility model and its equivalent scope described in book.
