Embodiment 1

[0027] First, refer to figure 1 The structure of the passenger conveyor 1 according to one embodiment of the present invention will be described. figure 1 It is a sectional view (longitudinal sectional view) along the longitudinal direction of the passenger conveyor 1 showing the structure of the passenger conveyor 1 according to one embodiment of the present invention.

[0028] Such as figure 1 As shown, the passenger conveying equipment (escalator) 1 has a frame 2 erected between the lower floor F1 and the upper floor F2, and in the frame 2, a plurality of pedals (steps) 10 are accommodated, and the plurality of pedals 10 pass through two The pedal chain 9 is connected in a loop, and circulates between the landing F1A of the lower floor F1 and the landing F2A of the upper floor F2. In addition, handrails 30 are erected on both sides of the step 10 in the width direction, and handrails 114 that move in the same direction as the step 10 are supported by the handrails 30 . T...

Embodiment 2

[0063] refer to Figure 6 , to describe the second embodiment. Figure 6 It is a figure which looked at the main part of the handrail driving apparatus 101 of the passenger conveyance apparatus 1 which concerns on one Example (second example) of this invention from above.

[0064] exist Figure 6 , shown in Figure 4 and Figure 5 In the above structure, the surface of the support portion 121 on which the height adjustment portion 118 is mounted (the surface facing the bearing 105) is provided with scales (scales) 124 arranged in a direction parallel to the direction in which the driven shaft 104 moves. exist Figure 6 in Figure 4 and Figure 5 In the structure shown, omit the Figure 6 Illustration of structures other than those shown. In addition, the structure of this embodiment can be applied to the first embodiment and its modification examples, and the structure of the scale (scale) 124 which is the characteristic part of this embodiment is demonstrated.

Abstract

The invention aims to easily adjust the levelness of a rotating shaft (driven shaft) of a driven wheel in a passenger conveying device. The passenger conveying device (1) is provided with a driving shaft (103), a driven shaft (104), a power transmission part (111) and a pair of bearings (105), wherein the power transmission part (111) transmits power from the driving shaft (103) to the driven shaft (104), and the bearings (105) rotatably support the driven shaft (104). Furthermore, the passenger conveying device (1) is provided with a height adjusting part (118), and the height adjusting part (118) is arranged on the end part side by taking the axial center of the driven shaft (104) as a reference. The height adjusting part (118) supports the driven shaft (104) from below and enables the height position of the end part side of the driven shaft (104) to be displaced.

Description

technical field [0001] The present invention relates to passenger transfer equipment. Background technique [0002] Conventionally, there is known a passenger transport facility described in JP 2015-48205 A (Patent Document 1). The passenger transport facility of Patent Document 1 includes: a bearing that supports the rotating shaft of a driven wheel; a trolley that fixes the bearing; a guide rail that supports the trolley so that it can move horizontally; The trolley exerts force in a direction away from the drive wheel to apply tension to the step chain; and a jacking portion that jacks up the trolley from the guide rail upward (jack-up bolt and lock nut) (refer to abstract). The tension device is installed so that a certain tension can always be obtained even if the step chain is elongated due to changes over time (refer to paragraph 0015). In the passenger conveying facility of Patent Document 1, when the rollers provided on the trolley are worn, the trolley cannot suf...
