Description

Moving walkway The invention relates to a moving walkway with an endless one Step plate conveyor horizontal impact deflection and each over axle-mounted rollers Step plates supported on both sides against guideways in coupling connection with endless tension members of flexible design in a parallel-spaced arrangement Currently Moving walkways of the type mentioned manufactured by the relevant industry must except the guideways for the step plates also for the flexible tension members, mostly are these pull chains, a storage system, for example additional guideways and / or have a corresponding number of chain wheels, each with at least two idler wheels, because the flexible tension members compensate for the shortened tendons at the deflection points to enable with each step plate only through a one-point bearing can be connected, sc that due to the relatively large distances there would be too much chain slack between the one-point bearings.

Because of this construction, the well-known moving walkways are, however in the case of increased susceptibility to failure with an uneconomically high cost and maintenance effort afflicted.

The invention has for its object to provide a wheelchair of the initially mentioned type with little construction effort so that he is at optimal Operational reliability is associated with lower production and maintenance costs.

This is achieved according to the invention in that on the chain hubs Sides of the step plates each with the exception of a fixed, roller axis the further roller axis is displaceable approximately parallel to the plane of the plate in the direction of rolling is stored and all roller axles are connected to the tension members.

Because of these simple construction measures, the tension members are connected to each step plate at least by a two-point bearing that is due to the relatively displaceable arrangement of the roller axles results in a shortening of the chords Allows at the deflection points. However, tread plates and tension members support one another due to their multipoint connection from each other in such a way that on each side of the Step plate belt is one of the two guide track or bearing arrangements that have been required up to now can be saved, whereby the production and maintenance costs in more economical Way to be diminished and the simpler construction of the moving walkway guarantees optimal operational safety. When using plate link chains as tension members, it is particularly advantageous if the roller axles are each shaped a chain pin formed for the link chains and possibly the rollers are mounted between the plates of a chain link on the chain pin.

This double function of the chain pins or roller axles is made possible a further reduction in the cost of the moving walkway.

An embodiment of the invention is shown schematically in the single Figure of the attached drawing is shown diagrammatically and is explained in more detail below explained.

In the drawing, two step plates 1 are one of a moving walkway endless step plate belt, which is deflected horizontally and axially by endless tension members of flexible training, for example link chains 2, in spaced parallel arrangement is driven. The step plates 1 are each over four rollers 5,6 mounted on roller axles 3,4 on both sides against guideways 7 supported and coupled to the link chains 2 via the roller axles 3.

Of the roller axles 3, 4 only the roller axles 3 are on the sides of the tread plates 1 close to the chain, while these are for the roller axles 4 have the latter each associated sliding guides 1a, in which the Roller axles 4 displaceable approximately parallel to the plane of the plate in the rolling direction stored uiid as well as the roller axles 3 are coupled to the link chains 2.

The bearing of the roller axles, which is displaceable relative to the roller axles 3 4 on the tread plates 1 enables the at the deflection points of the plate link chains 2 occurring tendon loss.

The roller axles 3, 4 are each in the form of a chain pin for the link chains 2 formed, between their link plates 2a in the embodiment both the rollers 5, 6 of the step plates and further rollers 8 on the chain pins are stored and guided in the Itührungsbahnen 7.

The invention is not based on the embodiment shown in the drawing limited. The chains 2 could also be located to the side of those running in the guideways 7 Rolls 5,6 of the tread plates 1 next to these mounted on the roller axles 3, 4 and / or be formed by other tension members of a flexible type. It would also be conceivable that the Step plates 1 on one side of the step plate belt each with only one axle-mounted To provide role and to couple the roller axle with the adjacent tension member.
