Definitions

the invention relates to an escalator or moving walk according to the preamble of claim 1.
Such an escalator is known from US-PS-42 49 649.
This escalator has a curved sheet as a guide for the Escalator steps or pallets. This is from the side the steps / pallets two essentially facing each other and U-shaped profiles open towards the inside of the escalator Sheet provided.
One of the two profiles points to his bottom of a channel on the width of the width corresponds to a step / pallet roll, so a side To support the step / pallet roll.
the other U-shaped rail is flat, so that it does not offer side guidance for the corresponding role.
the invention is based on the object Escalator or moving walk according to the preamble of To create claim 1 of the accuracy of Step / pallet guides, but especially with regard to the manufacturing cost, is improved, while still a long Lifetime of the step / pallet guides used should be realizable.
step / pallet guides The use of a deep-drawing process according to the invention surprisingly leads for the step / pallet guides to one whole number of advantages: deep drawing leads to each single-sided contact shoulders for the rollers, so that with symmetrical step / pallet guides worked on both sides can be. These in turn make it possible to use them quite well Inexpensive rolling bearings, for example roller ball bearings with conical rollers, after only a one-sided axial Load must be transferred. Wear can easily be caused by corresponding adjustment of the distance on one side adjustable step / pallet guidance can be compensated.
step / pallet guide according to the invention Manufacture particularly inexpensively because the undercut-free Construction suitable for deep drawing is.
deep drawing enables one improved precision compared to hot forming, so that transfer sheets made of deep-drawn sheet metal can also be realized can and then surprisingly without exciting post-processing measures have the desired shape accuracy.
the upper transfer sheet is made from deep-drawn sheet metal a higher sheet thickness is preferably provided for this, the mutual stabilization of the two with sheet metal for the chain roller and drag roller diverters allow the wall thickness also this sheet in the area suitable for deep drawing hold.
Step / pallet guides rest on the drive chains an escalator, at least under load Tension that in the area of the lower transition arches Walk up the chain rollers up the escalator and thus to the upper side legs of the U-shaped step / pallet guides issue.
the one on the shoulders on the lower side thighs guided chain rollers then basically turn backwards. To avoid excessive wear in this area, can use the shoulder on the lower side legs be provided with a sliding layer, or it can be in this Area of an abutment shoulder on the upper side leg be trained.
the solution according to the invention is for both escalators also suitable for moving walks. It is understood that with moving walks regularly called pallets and escalators the term stages is used regularly, here for the sake of simplicity for both types of transport devices keep the expression levels / pallets has been.
step / pallet guides 10 which consist of chain roller rails, Drag roller tracks and transfer bends for the Chain rollers as well as for the drag rollers on both sides of the Exist escalator or moving walk.
the in Fig. 1st The step / pallet guide 10 shown has a transfer sheet 12 for the trailing rollers and a transfer bow 14 for the chain rollers.
the two transfer bends 12 and 14 are cranked or preferably formed from deep-drawn sheet metal, so that they each a back 16 or 18 and bevelled edges 20 or 22 exhibit.
the bends are not preferred Cranking, but just produced by deep drawing.
the backs 16 and 18 face and face each other attached, for example by welding, by riveting or by screwing.
the transfer sheet 14 has one larger radius and serves as a chain roller conveyor 24.
the Umzhoubogen 12 has a smaller radius and serves as a drag roller conveyor 26. Both transfer arches 12 and 14 are arranged essentially coaxially to one another.
the drag roller conveyor is depending on the lower side legs 28 and 30 of the transfer sheet 12 are formed, with the inner side leg in the actual bypass area 30, the one with the smaller radius, the trailing roller valve 26 forms.
the side leg 28, which is also the outer side leg is at a suitable point approximately above the middle of the Umtechnologybogens a removal opening 32.
the removal opening 32 is intended for the steps or pallets Required for maintenance purposes from the closed guide the inner transfer sheet 12 or those connected to it To remove trailing roller rails. At the same time there is a visual inspection for the correct side distance for the tow rollers, running in the transfer sheet 12 possible.
the chain roller transfer bow 14 is through the attached to it Guide bow 12 stiffened in the middle. It consists of a substantially semicircular sheet, with additional Stiffening an edge flange 34 is provided, of the storage of the in conjunction with a folding tab 36 Um2020bogens 14 is used.
the deep-drawing direction points to the transfer sheet 14 to the inside of the escalator or moving walk, so that the chain roller conveyor through the outward-facing bend 22 is formed. After the chain rollers through the drive chains the escalators are under train, it is harmless that no counter-guidance is provided as with the trailing roller rail is.
the bevels 38 thus form shoulders for the side Guide of the chain rollers on the chain roller conveyor 24. Due to the symmetrical design of the step / pallet guides 10 on both sides of the escalator or moving walk thus ensuring safe cornering.
the chain roller rail 40 is essentially U-shaped, with the open side of the U facing the inside of the escalator points out, in this respect similar to the transfer sheet 12.
the lower Side leg 48 of chain roller rail 40 has the shoulder 46 for lateral support of the chain rollers while the upper side leg 50 runs straight. Even the chain roller track 40 can be easily including the Make shoulder 46 by deep drawing.
the distance between the upper side leg 50 and the Tread 44 is chosen so that the chain roller a little Has play in the chain roller track 40, at least that clearly is less than the height of the shoulder 46. That is also in the area of the transition arches not shown here lateral guidance guaranteed.
