(2) structure of handrail driving chain wheel 100
It follows that according to Fig. 2 and Fig. 3, the structure of handrail driving chain wheel 100 is illustrated.Additionally,
Handrail driving chain wheel 100 is also referred to as " belt wheel ".
The handrail driving chain of pair of right and left is taken turns by sprocket body 102, rotary shaft 104 and circle ring part 106
Constitute.
The sprocket body 102 that the metal of handrail driving chain wheel 100 is made is rondelle, the rotary shaft of level
104 its centers through.The handrail driving chain wheel 100 of opposite side is co-axially mounted in rotary shaft 104.Rubber
The circle ring part 106 that glue is made is entrenched in the peripheral part of the sprocket body 102 of rondelle.Circle ring part 106
The thickness in direction, footpath be 2 cm, be contracted to 1 cm when depressed power.Handrail
The inner side of 38 is erected at the lower peripheral part of handrail driving chain wheel 100.
In the lower outer periphery portion of handrail driving chain wheel 100, as it has been described above, be configured with pressing component 70.?
In pressing component 70, multiple pressing roller 74 are rotatably arranged in circle in the way of the predetermined distance of interval
On the base station 72 of camber, all of pressing roller 74 presses from Jing Nei direction, lateral (center position) and holds up
Hand strap 38, described handrail 38 is set up in the lower peripheral part of handrail driving chain wheel 100.
The bottom of the base station 72 of circular arc type is fixed on truss 12, and the upper end of base station 72 is by spring
Supporting parts 78 are fixed on truss 12.Spring bearing member 78 is by helical spring 80, external thread rod
82, fixing end 84, mobile terminal 86 and nut 88 are constituted.As in figure 2 it is shown, spring bearing member 78
The lower end of external thread rod 82 be fixed on the upper end of base station 72, mobile terminal 86 is entrenched in external thread rod 82
Upper end, mobile terminal 86 is fixed with the upper end of helical spring 80, described helical spring 80 has court
To the active force of shrinkage direction.Fixing end 84 it is fixed with, this fixing end 84 in the lower end of helical spring 80
It is fixed on truss 12.Mobile terminal 86 is moved along external thread rod 82 according to the fastening situation of nut 88,
The active force making helical spring 80 changes.Thereby, it is possible to adjust multiple pressing roller 74 of base station 72
The power of direction pressing in the footpath of handrail driving chain wheel 100.
In the upper layer side of handrail driving chain wheel 100, as it has been described above, guide roller group 64 is arranged on truss 12
On.In guide roller group 64, the base station 90 of circular arc type is configured with in the way of rotatable multiple
Guide roller 92, and guide handrail 38 from inlet portion 46 to the lower peripheral part of handrail driving chain wheel 100.
At the lower layer side of handrail driving chain wheel 100, as it has been described above, guide roller group 66 is arranged on truss 12
On.In guide roller group 66, the base station 94 of circular arc type is configured with in the way of rotatable multiple
Guide roller 96, and guide, to lower layer side, the handrail being drawn out from the lower peripheral part of handrail driving chain wheel 100
38。
(3) operating state of handrail driving chain wheel 100
The operating state of handrail driving chain wheel 100 is illustrated.When handrail driving chain wheel 100 rotation,
The handrail 38 being pressed against on handrail driving chain wheel 100 by pressing component 70 runs.In this situation
Under, if the diameter (pulley diameters) of handrail driving chain wheel 100 becomes big, then the rotation speed of its peripheral part
Degree will accelerate, and the speed of service of handrail 38 can accelerate.If the diameter (band of handrail driving chain wheel 100
Wheel diameter) diminish, then the rotary speed of its peripheral part is by slack-off, and the speed of service of handrail 38 can be slack-off.
In the present embodiment, owing to being provided with, at the peripheral part of handrail driving chain wheel 100, the annulus that rubber is made
Parts 106, therefore, if pressing component 70 pressing roller 74 produce by pressure strengthen, then annular portion
Part 106 will be pressed further, handrail driving chain wheel 100 diameter can diminish, its degree diminished with
The degree being pressed is suitable.Pressure should be pressed according to the fastening situation of the nut 88 of spring bearing member 78
Change.
In the case of the speed of service wanting raising handrail 38, operator unscrew spring bearing member
The nut 88 of 78, with weaken that pressing component 70 produces by pressure, increase handrail driving chain wheel 100
Diameter, thus spin up speed, improve the speed of service of handrail 38.
In the case of the speed of service wanting reduction handrail 38, operator tighten spring bearing member
The nut 88 of 78, with strengthen that pressing component 70 produces by pressure, reduce handrail driving chain wheel 100
Diameter, thus de-spin, reduce the speed of service of handrail 38.
Additionally, in the above description, only the side of the handrail driving chain wheel 100 of pair of right and left is carried out
Explanation, when also there is the difference of the speed of service between step 30 and handrail 38 in opposite side, energy
Enough it is done in the same fashion adjustment.It addition, when step 30 is identical with the speed of service of handrail 38,
Without unilateral handrail driving chain wheel 100 is adjusted.
(4) technique effect
According to present embodiment, by adjusting the nut 88 of spring bearing member to adjust pressing component 70
By pressure, the shape in the direction, footpath of circle ring part 106 changes, handrail driving chain wheel 100 straight
Footpath changes.Therefore, it is possible to adjust the rotary speed of the peripheral part of handrail driving chain wheel 100, therewith
The speed of service of handrail 38 can be adjusted.
Further, since can be to handrail driving chain wheel 100 with guide roller group 66 by guide roller group 64
Lower peripheral part guides handrail 38, therefore, it is possible to make the pressing effect of pressing component 70 relatively reliable.
(5) variation
In the above-described embodiment, circle ring part is that rubber is made, but, as long as instead
Have parts springy, for example, it is also possible to be pneumatic tire etc..
It addition, in the above-described embodiment, it is illustrated in the way of being applied in escalator 10,
But it is also possible to be instead applied in moving sidewalk.
Above, an embodiment of the present utility model is illustrated, but this embodiment is to make
Propose for example, it is not intended that limit the protection domain of utility model.The embodiment of these novelties can
To implement in other various modes, in the range of without departing from utility model objective, various province can be carried out
Omit, replace, change.These embodiments or its deformation, be included in protection domain or the ancestor of utility model
In purport, it is also contained in equally in the protection domain of the utility model described in claims and equivalent thereof.
