Problems solved by technology

[0003] Considering that in the above-mentioned conventional handrail driving device, since the frictional force between the driving roller and the canvas surface of the handrail becomes high, although the driving roller slips and the handrail does not usually stop, the handrail that is in contact with the driving roller When the canvas surface is wet with water droplets such as rain, the friction force between the canvas surface of the handrail and the driving roller will decrease, and the handrail will stop

Embodiment approach 1

[0021] figure 1 It is a schematic configuration diagram of a passenger conveyor equipped with a handrail driving device according to Embodiment 1 of the present invention, figure 2 yes figure 1 Longitudinal sectional view of the armrest drive shown. In addition, in each of the above-mentioned figures, descriptions of thicknesses, dimensions, enlargement-reduction ratios, etc. of each member do not correspond to actual conditions for ease of understanding and description.

[0022] Such as figure 1 As shown, the passenger conveyor belt 100 involved in Embodiment 1 includes: a driving machine 2, which is arranged in the upper machine room 1; a driving sprocket 3, which is driven by the driving machine 2; a driving chain 6 And the step chain 7, the drive chain 6 and the step chain 7 are wound on the drive sprocket 3 and the driven sprocket 5 arranged in the lower machine room 4; a plurality of steps (steps) 8, the plurality of steps (steps) 8 is installed on the step chain 7,...

Embodiment approach 2

[0031] Next, the handrail driving device according to Embodiment 2 of the present invention will be described. image 3 It is a longitudinal cross-sectional view of the handrail driving device according to Embodiment 2. In addition, in image 3 In , for ease of understanding and description, descriptions of thicknesses, dimensions, and scales of enlargement and reduction of each member differ from actual conditions. In addition, in Embodiment 2, the same code|symbol is attached|subjected to the same member as the handrail driving apparatus 11 demonstrated in Embodiment 1, and the detailed description is abbreviate|omitted.

[0032] The handrail driving device 211 according to Embodiment 2 can replace figure 1 The illustrated handrail driving device 11 is mounted on the passenger conveyor 100 .

[0033] Such as image 3 As shown, the main difference between the handrail driving device 211 according to the second embodiment and the handrail driving device 11 according to the...

Abstract

The invention provides a handrail drive device for a passenger conveyor belt and a passenger conveyor belt comprising the same. Even if a canvas surface of a handrail is moistened by rain, the handrail drive device can operate with the same speed as steps and prevent rainwater from intruding into bearings. The handrail drive device (11(211)) of the passenger conveyor belt comprises a plurality of driving rollers (17) clamping and driving a handrail (10) and driven rollers (18); a shaft (13) fixed to a frame (12); bearings (14a, 14b) sandwiched between the shaft (13) and the driving rollers (117). Rainwater intrusion prevention parts capable of preventing rainwater from intruding into the bearings (14a) are arranged on the side surfaces of the outer sides of the driving rollers (17).

Description

technical field [0001] The present invention relates to a handrail driving device of a passenger conveyor belt and a passenger conveyor belt provided with the handrail driving device. Background technique [0002] Conventionally, in passenger conveyor belts, handrails that run at the same speed as steps are provided in order to transport passengers safely. The handrail driving device that drives the handrail clamps the handrail with a plurality of driving rollers and driven rollers to drive the handrail. [0003] Considering that in the above-mentioned conventional handrail driving device, since the frictional force between the driving roller and the canvas surface of the handrail becomes high, although the driving roller slips and the handrail does not usually stop, the handrail that is in contact with the driving roller When the canvas surface is wet with water droplets such as rain, the friction force between the canvas surface of the handrail and the drive roller decrea...
