Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • Corresponding chain rollers and step rollers typically run on separate rails, which are supported on a frame formed from profiles.
  • the rails In order to form the desired step pattern or to provide the desired pallet band, the rails must run at a predetermined height and be supported there securely and in particular also stiffly. If the rail deflected too much, the passenger would not only get a feeling of insecurity; it would also be feared that the asymmetrical load of the step or pallet belt would exceed the predetermined play, so that the step or pallet rubbed.
  • the frames used are particularly stiff and that they do not bend beyond the specified tolerances, even in the event of the maximum permissible operating load of the escalator, but also, for example, of a self-supporting moving walk.
  • the frames are prefabricated in pieces of 2 m or 3 m, for example, by welding the profiles in the factory. They are then brought to the desired location on site with cranes or lifting platforms or the like and welded to one another there.
  • This solution is extremely time-consuming and personnel-intensive, requires heavy equipment and contributes significantly to the construction costs for the escalator.
  • the invention has for its object to provide an escalator or moving walk according to the preamble of claim 1, which builds lighter without sacrificing rigidity, so that it can also be used for buildings with low resilience, but the manufacturing costs should still be reduced.
  • the solution according to the invention provides for the use of perforated plates which build up the frame as a perforated plate frame.
  • perforated plate Even if the term perforated plate is used here, it goes without saying that this does not mean a perforated plate which is known per se, but rather a specially produced plate into which large holes are made, which alternately extend in different sizes, the largest holes, for example, definitely can take up half the height of a side panel, for example, can have a diameter of 50 cm.
  • perforated plates of this type have the advantage that even with permanent vibration stress, such as that encountered when driving stairs occurs, the material fatigue is particularly low, even though a comparatively low weight with high strength can be manufactured inexpensively. Hence, the spreading of vibrations is made more difficult by the unevenly arranged holes, so that the dreaded resonances are suppressed.
  • a perforated sheet according to the invention can be produced in any suitable manner.
  • the perforated sheets according to the invention can be produced by cutting, for example laser cutting, but also any other sheet metal cutting techniques.
  • the perforated sheet metal structure according to the invention enables a significantly reduced weight to be produced compared to the realization with welded U and T profiles; Surprisingly, with the same deflection of an escalator of 20 m in length, the weight of the frame is reduced to about half.
  • the prefabricated longitudinal sections of side plates and bottom plates can be provided much more cheaply. Thanks to the greatly reduced wall thicknesses, the frame can be machined better on site, and the significantly reduced weight significantly reduces the load-bearing capacity of the floor slabs. The heavy equipment used for assembly can also be reduced, although the use of cranes may not be necessary.
  • the solution according to the invention results in an extremely rigid support structure for the frame.
  • the weld seams provided on the floor plate and side plates are preferably not provided at the same longitudinal extension point, but offset against one another, which additionally benefits the stiffening. It is also provided in an advantageous embodiment to weld small sheet metal ribs.
  • the material removal of the cut-out sheet metal circles for producing the large perforated sheet according to the invention results in essentially no weakening of the sheet used, however a significant weight reduction of, for example, 40%, depending on the definition of the hole cutouts. While bolt circles are preferred, it goes without saying that elliptical holes may also have advantages.
  • cut-out bolt circles represent high-quality and reusable steel sheet, so that the solution according to the invention also does not entail any cost disadvantages in waste disposal.
  • the prefabricated sheet metal sections can have a length of one meter and a grid division of 4 units can be provided.
  • the sheets cut to length in the grid dimension overlap one another, so that the adjustment area which is provided once per escalator or moving walk is associated with certain weight disadvantages over a length of less than 1 meter, At this critical point, however, no rigidity disadvantages are to be expected.
  • the upper run and the lower run of the step or pallet belt run clearly apart from each other. At the entrance and exit, the distance is determined by the diameter of the drive wheel or deflection wheel of the step or pallet chain.
  • cross struts can consist of folded sheet metal, but can also be designed as profiles.
  • the transfer arches are formed adjacent to the entrance and exit from perforated sheet metal.
  • a corresponding sheet with a width of, for example, 1.50 m can be prefabricated as a base, similar to the floor sheet, during which the course of the escalator or the Moving walkway extending side panels made of sheet metal with a width of about 1 m can be realized.
  • Appropriate protruding areas can also be used to implement supports for the comb plates in such side plates for entry and exit.
  • flat sheets are lasered. If required, the metal sheets can also be folded at the ends, for example by rolling. It goes without saying that the dimensioning of the sheets is adapted to the requirements in order to provide the desired strength.
  • the side plates are placed on the base plate and welded there, preferably in a continuous weld in prefabrication ex works. It goes without saying that any other suitable connection can also be used here, if appropriate also a riveted connection after a corresponding bending of one of the sheets.
  • Figure 1 is a side view of part of an embodiment of an escalator according to the invention, namely a side plate.
  • FIG. 2 shows a side view of part of the embodiment according to FIG. 1, namely another side plate; 3 shows a section through the escalator according to the invention in the embodiment according to FIG. 1, along the line AA;
  • FIG. 4 shows a section through the escalator according to the invention in the embodiment according to FIG. 1, along the line B-B;
  • FIG. 5 shows a section through the escalator according to the invention in the embodiment according to FIG. 2, along the line C-C.
  • the escalator 10 partially shown in FIG. 1 in the embodiment according to the invention has a perforated plate frame 12 which is essentially U-shaped.
  • Fig. 1 shows a side view of the U, ie a view of one of the side legs.
  • the side legs are formed by side plates, of which a side plate 14 can be seen from FIG. 1, while the middle leg is formed by a bottom plate, as can be seen in the form of the bottom plate 18 from FIG. 3.
  • the side plate 14 shown in FIG. 1 is in the form of a side plate section which is intended for the lower entry or exit of the escalator.
  • Substantially more side plates are connected to the part of the side plate 14 which points obliquely upward, so that the entire side plates of the escalator are formed by the combination of the end side plates shown in FIGS. 1 and 2 and central side plates extending between them ,
  • the side plate 14 has a large-hole plate structure 20.
  • a hole cutout 22 extends over a height of almost 60% of the side plate 14, and more closely adjacent to the upper edge of the side plate 14.
  • hole transitions 26 are formed, the width, size and position as well as inclination of which can be adapted to the requirements in wide areas.
  • the alignment of adjacent hole transitions is preferably different from one another.
  • the hole cutouts 22 and 24 are not provided alternately at the bottom and top of the side plate. Rather, the hole cutout 22 is adjacent to a rather small hole cutout 28, which is likewise arranged at the upper end, a quite narrow hole transition 30 extending between the hole cutout 22 and the hole cutout 28. In the manner shown in FIG. 1, further hole cutouts 31, 32 and 33 extend in different distributions, hole transitions 34, 35 and 36 being formed between adjacent hole cutouts.
  • Hole cutouts or holes that are adjacent to one another are at least either not provided at the same height or do not have the same diameter. This arrangement by means of a stochastically distributed arrangement successfully achieves a low-resonance structure of the large perforated plate 20 according to the invention.
  • the perforated sheets are produced by cutting out corresponding circles 32 from the sheet which is initially completely present.
  • the cutting can be done in any suitable manner, but preferably by laser cutting.
  • the holes are preferably round, so that the introduction of force is evened out without a notch effect.
  • the perforated plate structure 20 shown in FIG. 1 is additionally stiffened via further ribs. Ribs 37 and 39 are mentioned here as examples.
  • the ribs 37 run through the hole transition 30 perpendicular to the main orientation of the side plate 14, almost up to the bottom plate 18, on the other hand, the ribs 39 run through the hole transition 35 and essentially also extend over the entire height of the side plate 14.
  • the ribs extend depending on the inside, for example over a width of 5 cm. They are formed by sheet metal strips welded there.
  • cross struts 40 are provided approximately in the middle of the hole transitions 35 and extend between the two side legs of the U. Such cross struts can be seen, for example, from FIGS. 4 and 5.
  • a projecting portion 42 is provided on the top of the side panels 14 in a manner as shown in FIGS. 1 and 3.
  • the comb plate of the escalator according to the invention can be stored at this point.
  • the frame according to the invention is closed with an L-profile 46, which extends between the two side walls 14.
  • FIG. 1 A corresponding construction of a side plate section for the upper entry or exit can be seen in FIG.
  • a projecting area 48 is also provided, which extends beyond the top web 22 and the configuration of which can be seen in FIG. 5.
  • the side plates 14 according to the invention are connected by a bottom plate 18.
  • the base plate 18 preferably also has hole cutouts 50 (not shown). Preferably, no cutouts are provided in the area of the ribs 38, that is to say quite far to the side, in order to ensure full support of the welded-on ribs 38.
  • the frame of the escalator according to the invention is extremely rigid both as a section and in a welded-together form and has a particularly low weight in relation to this. It goes without saying that the width and arrangement of the hole cutouts can be adapted to the requirements over a wide range. Likewise, manufacturing is not limited to laser cutting and laser welding; any other type of material separation and material addition can be used. The sheet thickness can also be varied over a wide range depending on the requirement profile in order to provide the desired strength.
