Problems solved by technology

[0003] Pallet belts or step belts can be replaced relatively easily, while the replacement of conveyor sprockets and deflection sprockets requires a very high level of work effort, which leads to prolonged shutdowns of the associated conveyors

Embodiment Construction

[0030] figure 1 An escalator 1 with a guardrail 2 and a handrail 3 revolving around the guardrail 2 is schematically shown in side view. The escalator 1 connects the lower floor E1 with the upper floor E2 , wherein the carrier structure 4 , which is designed as a frame structure, serves as a carrier for the guardrail 2 and as a mounting frame for the other components of the escalator 1 . The carrier structure 4 also has a first deflection area 5 and a second deflection area 6 . Between the first deflection area 5 and the second deflection area 6 , a step belt 7 is arranged in the support structure 4 in a revolving manner. Step belt 7 has at least one in figure 1 The articulated chain 8 is only partially shown in the figure, on which a step 9 is arranged. The step belt 7 has a forward feed 10 , by means of which persons or goods are conveyed, and a return 11 for returning the steps 9 . The steps 9 and the articulated chain 8 are guided in the forward section 10 by means of ...

Abstract

The invention relates to an escalator (1) having a step band (7) or to a moving walkway having a pallet band, wherein the step band (7) or pallet band has at least one link chain (8) which comprises engagement points (27) which are arranged so as to follow one another at theoretically identical engagement spacings (L). The escalator (1) or the moving walkway has a first deflection region and a second deflection region with at least one conveying chain sprocket (14). The at least one link chain (8) is arranged so as to circulate between the deflection regions, and the engagement points (27) engage into tooth gaps (22) of the conveying chain sprocket (14) and optionally into tooth gaps (22) of at least one deflection chain sprocket which is arranged in the first deflection region (5). The at least one conveying chain sprocket (14) and / or the at least one deflection chain sprocket have / has a pitch circle (23) with a pitch (T) which is related to the tooth gaps (22) and corresponds to half an engagement spacing (E) of the link chain (8).

Description

technical field [0001] The invention relates to an escalator with a step belt or a moving walkway with a pallet belt. The step or pallet belt comprises at least one hinged chain on which the steps or pallets are arranged. Background technique [0002] Escalators and moving walks are subject to high, variable loads due to fluctuating user numbers and have long operating times of 10 to 18 hours per day. In public transport buildings such as airports, railway stations or subway stations, escalators and moving walks may even be in continuous use around the clock. Correspondingly, the moving parts of the conveyor are subject to high wear and must therefore be maintained intensively and thoroughly. Parts that are subject to a high degree of wear and need to be replaced regularly (wear parts) are in particular pallet belts or step belts as well as conveyor sprockets and deflection sprockets. The transfer sprocket drives the articulating chain, and the diverting sprocket is used ...
