Definitions
- the present invention relates to an escalator.
- Escalators sometimes referred to as escalators, are used to carry people between two levels along a travel path.
- the escalator has this for a variety of treads, which along the travel path
- Each of the treads has a tread, which is directed in the lead of the escalator up and can be accessed by the persons to be transported. At a rear end of this tread surface seen in a conveying direction upwards adjoins a running to this tread surface setting surface.
- the treads are connected to each other via a traction means, such as a step chain or a belt and form a step band.
- a drive unit can drive the step band or the step chain and thus shift the treads in a flow along the travel path.
- the lead of the travel extends in a bottom-upwardly-promoting escalator from a lower horizontal area adjacent to an access to the escalator over a central inclined area extending to an upper horizontal area adjacent to an exit of the escalator. Since the step band or the step chain is formed circumferentially, the treads are in a return in
- Each of the treads typically has a forward gearing structure with adjacent ribs and grooves therebetween on a forwardly directed transverse surface to the tread surface. Further, each of the treads typically has a rearward portion at a rearward portion of the seating surface
- Gear structure also with adjacent ribs and intermediate grooves on.
- the front and rear toothing structures are adapted to one another and are preferably designed to be complementary to one another in such a way that they can intermesh with one another during the advance of the escalator.
- the front Engage tooth structure of one of the treads in the rear tooth structure of the adjacent tread such that the ribs of the front
- Treads are designed such a meandering that a risk that an object such as a shoe of a passenger entangled therein is minimized.
- intermeshing of adjacent treads may also aid in guiding the treads, i.e., adjacent treads can hardly move in a direction transverse to the travel relative to each other.
- Gearing structures as safe as possible and could mesh with each other with the least possible gap between adjacent tooth structures.
- Measures are performed laterally to their deviation from the travel in one Direction transverse to the path to prevent, however, which additional structural measures were required and in many cases increased wear on components of the escalator.
- JP 3 790 788 B2 JP 3 790 788 B2.
- this requires a special and very complex deflection mechanism, so that the treads of the treads are directed as in the flow, and in the return upwards.
- an escalator which has a plurality of treads arranged successively along a travel path, wherein each tread includes a tread surface and a setting surface adjacent to a rear end of the tread surface and extending transversely to the tread surface.
- the escalator has a guide rail assembly comprising a chain roller guide rail for guiding chain rollers of the treads and a tow bar guide rail for guiding tugs of the treads.
- Guide rails extend over a lead from a lower, horizontally extending portion of the travel path, over a central inclined portion of the travel path, to an upper, horizontally extending portion of the travel path and via an inverted return path.
- Each tread has a front tooth structure and a rear tooth structure, wherein the front and the rear tooth structure are formed complementary to each other so that mutually facing tooth structures of adjacent treads can mesh with each other.
- the chain roller guide rail and / or the guide roller guide rail has two curvature regions of strong curvature bordering on the upper and middle regions and an intervening curvature region of weaker curvature. This special design of the guide rail arrangement makes it possible for the toothing structures of adjacent tread steps to mesh with one another, at least even in the central, inclined region of the return.
- Guide rail assembly which leads the treads, especially where it leads the treads along the return, can be suitably modified and specially designed so that adjacent treads are brought together in such a way that it to a safe engagement of their opposing Vernierungs Modellen and thus a combing arrangement comes.
- Guide rail assembly can be performed intermeshing intermeshing also during the return, on the one hand, a reduction of the necessary space for the escalator space allows.
- the treads are moved closer together during the return, so that the space required for the return of the escalator is significantly reduced.
- the option of intermeshing the treads even during the return, allows better lateral guidance of the treads during retrace, ie a greater limitation of their range of motion in a direction transverse to the longitudinal direction of the travel. This allows
- the guide rail arrangement has a chain roller guide rail for guiding chain rollers of the treads and a drag roller guide rail for guiding tugs of the treads.
- various rollers in the form of chain rollers and tow rollers are typically attached to the treads in order to be able to move the treads guided along the travel path. It has been found advantageous to guide these different roles using different guide rails.
- the chain rollers are here guided along the chain roller guide rail and the tow rollers are guided along the guide roller guide rail.
- the fact that the two types of guide rails can be designed differently and in particular the respective rollers along different paths, which need not necessarily be parallel, can be achieved that a held by the guided chain and drag rollers tread during the process in desired directions can be tilted or pivoted. Such tilting or
- Pivoting of treads can be advantageously used to approximate the treads during passage of the return in a manner in which their teeth can be introduced intermeshingly easily and without undue risk of collisions or tilting.
- the guide rail assembly should have at least one chain roller guide rail and at least one drag roller guide rail. Usually, however, are attached to the treads chain rollers and tow rollers on both opposite sides, so usually in the
- Towing roller guide rails are provided. These are each along opposite sides of the travel and at a distance which corresponds approximately to the width of the intermediate treads arranged.
- chain roller is to be interpreted broadly, that is, that they do not necessarily have to be part of a chain. Rather, the term stands for those roles through which the traction means connecting the steps is guided.
- each tread may have near its front end a chain roller spaced orthogonally to the tread at a first pitch and near its rear end a tow roller spaced orthogonal to the tread at a second distance greater than the first distance.
- the chain roller guide rail and the guide roller guide rail are in this case in the upper horizontally extending portion of the travel further spaced apart than in the middle inclined extending portion of the travel.
- Transition region between the upper horizontally extending portion and the central inclined portion of the path so differently curved curved formed relative to each other that adjacent guided along the guide rail assembly treads are performed such that the front tooth structure of a tread of the rear tooth structure of the adjacent tread with a gap is as long as both treads are moved along the upper horizontal region of the travel, and the front tooth structure of the tread is introduced into the rear tooth structure of the adjacent tread in a region of the set surface, the gap between them in the horizontal direction successively decreasing combing, if both Treads are moved sequentially along the transition region in the middle inclined portion of the travel.
- At least one, preferably at least two, chain rollers and at least one, preferably at least two, drag rollers are preferably attached to each tread.
- the chain rollers are mounted near the front end of the tread and the tow rollers near the rear end. A distance of the rollers to the tread of the tread is smaller for the chain rollers than for the tow rollers. This can be caused, inter alia, that the tread during the run with their chain and tow rollers along a single guide rail or alternatively along two mutually parallel
- Chain roller and roller guide rails can be moved in such a way that their tread surface is substantially horizontal.
- the chain rollers are now guided along the chain roller guide rail provided there, whereas the tow rollers are guided along the separate thereto roller conveyor guide rail.
- the chain roller guide rail and the guide roller guide rail are spaced from each other in the vertical direction. A distance between these different ones
- guide rails is not constant over the entire travel path of the return line. Instead, the distance between the chain roller guide rail and the guide roller guide rail in the upper horizontal region of the travel path should be greater than in the adjoining mean inclined portion of the travel path. Due to the closely spaced chain and roller guide rails, the treads can be arranged closer to each other at least in the middle inclined region of the travel, in particular so close that their opposite tooth structures can intermesh intermeshing. Due to the close spacing of the chain and track roller guide rails from each other while a necessary space for the escalator space can be significantly reduced.
- Gearing structures can be critical. In particular, there may be a risk that the opposing tooth structures are not positioned correctly complementary to one another, so that ribs of one tooth structure do not fit exactly in grooves of the other tooth structure. This can lead to collisions between the adjacent treads in the region of their tooth structures, whereby the tooth structures can be damaged. In particular, it can lead to increased wear on the toothing structures. In the worst case, the gearing structures can even be bent, which can result in significant risks for both the integrity of the escalator and passengers using the escalator. Exactly for these reasons, therefore, it has been assumed that a meshing intervening displacing the treads in the return of the travel is too risky.
- the chain roller guide rail and the guide roller guide rail in a certain area differently curved relative to each other in a transition region between the upper horizontal region and the central inclined region of the travel be formed.
- the chain roller guide rail and the guide roller guide rail can be arranged substantially straight and parallel to each other in wide parts of the upper horizontal region and the central inclined region of the travel path.
- the two guide rails must each be curved and it has been recognized that it may be advantageous to provide the two guide rails in different ways, i. with different radii of curvature and / or a different curvature, to bend.
- the different curvature courses of the different guide rails should be designed such that adjacent treads, which are guided along the guide rail arrangement, are guided such that the front
- Teeth structure of a tread is spaced from the rear tooth structure of the adjacent tread over a gap, as long as the two treads are moved along the upper horizontal region of the travel path. However, as soon as the treads successively enter the transition region and along this transition region in the middle inclined region of the
- the front tooth structure of the tread is to be inserted in the rear tooth structure of the adjacent tread in the horizontal direction, wherein the movement of the treads relative to each other should be such that the front tooth structure of a tread in a portion of the setting surface of the adjacent tread in the interlocking structure provided there is introduced and in the process a gap between the two interlocking structures is successively reduced in the horizontal direction until the two interlocking structures are inserted into one another in a combing manner.
- the term "horizontal" is in this Context interpreted and can be interpreted as meaning that it should include directions substantially parallel to one of the guide rails.
- Teeth structure of a tread approached from below to the tread of the adjacent tread, which would present the significant risk that the
- the tooth structures of both treads mesh better. Even in the event that the two toothing structures are not aligned exactly complementary to each other, a slight offset between the front tooth structure of a tread and the rear tooth structure of the adjacent tread is usually by slight lateral relative movements of the two treads when they are moved horizontally toward each other, be compensated, in particular since the rear toothing structure is formed on the usually slightly curved running surface of the tread.
- Towing roller guide rail formed in the transition region so different curved relative to each other, that a distance between the chain roller guide rail and the roller guide rail from the upper horizontally extending portion initially increases and then gradually decreases towards the middle inclined region successively decreases.
- the chain roller guide rail and the guide roller guide rail are arranged parallel to each other and at a first distance from each other over large parts of the upper horizontally extending portion of the travel path. At the Entry into the transition region, this distance preferably increases initially, in order then to decrease again in the further course of the transition region to the inclined region of the travel path and even to become smaller than the first distance.
- the tread steps guided on the guide rails via their chain rollers and tow rollers are guided in a specific manner and, in particular, tilted relative to one another.
- Such tipping of the treads while approaching adjacent treads may be used to move adjacent treads in a desired manner toward one another in a desired manner such that the eventual collision of their tiling structures minimizes the risk of collisions.
- Transition region two regions near the bend of strong curvature with an intermediate curvature region of weaker curvature.
- Transition region where it merges into the upper horizontal region, initially a greater curvature, then runs on the way to the middle inclined region initially with a smaller curvature, and then at the other boundary of the transition region before the transition to the middle inclined area again take a stronger curvature. Due to such a curved configuration of the chain roller guide rail guided chain rollers can be displaced when passing through the transition region in a manner that thereby adjusts a desired movement of the guided tread, in particular a desired tilting of the tread.
- the chain roller guide rail can have a greater curvature in at least one of the region of curvature close to the border than the track roller guide rail in the associated region.
- the chain roller guide rail and the roller guide rail may be parallel to each other in the upper horizontal area and in the middle inclined area, one
- the chain roller guide rail is curved more strongly than the tow roller guide rail at least in one of the respective border region near curvature areas.
- the sprocket guide rail is in both border regions near the bend, i. both adjacent to the upper horizontal region and adjacent to the central inclined region, more curved than the lug guide rail.
- Curvature areas for increased tilting of the guided tread which is stronger than in a case in which the two guide rails would be uniformly and synchronously curved with each other.
- the "associated area" of the track roller guide rail can be understood to mean that area which is closest to the relevant area of the chain roller guide rail or over which the track roller of a tread roller rolls when the chain roller of the same step steps over the area concerned Chain roller guide rail rolls.
- the sprocket guide rail may have less curvature in the intermediate curvature region than the track roller guide rail in an associated region.
- the chain roller guide rail is preferably less curved than the roller conveyor guide rail in the associated area.
- the chain roller guide rail can even be flat in the intermediate curvature area, ie have a curvature of zero.
- the chain roller guide rail can be curved in its boundary regions strongly, in particular more strongly than associated areas of the guide roller guide rail, but in the intermediate curvature region run flat.
- the intervening area is unbent, i. just.
- the intermediate region is slightly curved in an opposite direction, i. both boundary regions are convexly curved and the intermediate region is slightly concave, at least in some areas.
- Curvatures according to an embodiment the chain roller guide rail and the guide roller guide rail in the transition region so differently curved relative to each other to be formed that a tread when driving through the transition region from the upper horizontal region coming forth initially with its front tooth structure of the rear
- Gearing structure of the adjacent tread is tilted away and then tilted opposite tilting towards the rear tooth structure of the adjacent
- the adjacent ribs and intermediate grooves of the front spline structure and the rear spline structure preferably have a conical cross section.
- the conical cross sections of ribs and grooves can have a flank angle between 0.5 ° and 10 °, preferably between 1 ° and 5 °, particularly preferably of 3 °.
