Embodiment Construction

[0016] The handrail drive device according to the invention is also suitable for moving walkways with panels. In this description only the term "escalator" is used, but the content of the described embodiments is also applicable to moving walkways.

[0017] figure 1 It is a side view of the escalator 1, which connects the first floor E1 and the second floor E2 together. The escalator 1 has a step belt consisting of steps. The handrail 2 with the forward stroke 2.1 and the return stroke 2.2 is arranged on the guardrail 3, and the lower end of the guardrail is fixed by a guardrail seat 3.1. A handrail driving device 4 arranged on the frame 5 drives the handrail 2 . The frame 5 of the escalator 1 supports the guardrail seat 3.1. In the range of the upper end and the lower end of the escalator 1, a comb-tooth plate is provided, and the comb-tooth plate ensures reliable movement from the fixed part of the escalator 1 to the moving step belt or from the moving step belt to the f...

Abstract

In this handrail-drive, a chain wheel 4.9 of the driving wheel is connected with the driving wheel 4.15 holding a driving wheel tire 4.1 by an axle 4.16, and the axle 4.16 is rotatably held by a bearings 4.17. The driving wheel tire 4.1 filled with gas, for example, compressed air is applied on a removable wheel rim 4.18 arranged on the axle 4.16 to cover it. The driving wheel tire 4.1 is adapted to a shape of the handrail. The handrail is only slightly or negligibly deformed owing to spring characteristic and air cushion characteristic of the driving wheel tire 4.1 and large contact surface obtained from it.

Description

technical field [0001] The invention relates to an escalator or moving walkway consisting of a frame, a step belt with steps or a slab belt with plates for transporting people and / or goods and a guardrail supported on each side by a guardrail seat and with handrails Composition, the handrail driving device drives the handrail. Background technique [0002] A linear handrail drive for an escalator is disclosed in EP640553A2. Two driving wheels move the handrail on the inner side of the handrail in a friction fit mode, wherein a pressing wheel is arranged on the outer side of the handrail for each driving wheel, and the pressing wheel presses the handrail against the driving wheel. [0003] A disadvantage of this known device is that the pressure wheel must exert a high pressure force in order to avoid slippage between the armrest and the drive wheel. High extrusion work will shorten the life of the drive and pressure rollers. Contents of the invention [0004] The object...
