Definitions

  • the present invention is encompassed within the technical field of escalators and moving walkaways, specifically to the truss and structural elements for holding the mechanism of the escalator/moving walkway, and more specifically, to modular structures assembled together to make a whole escalator/moving walkway truss.
  • the invention relates, in particular, to an escalator/moving walkway modular truss which is assembled by means of cold joining technology, providing accurate final dimensions, and being able to support and position the whole guiding.
  • escalator and moving walkway truss is intended merely as a structural element with the only aim of holding the mechanisms located inside the escalator or the moving walkway.
  • FIG. 1 shows and overall view of a current escalator/moving walkway modular truss with those three modules.
  • These modules consist of a plurality of welded steel tubes or hot rolled profiles, which due to bad tolerances and thermal stresses in the manufacturing process made by welding, form a deformed and misaligned truss.
  • These deformations in the welded structure make the following assembly phase of guide supports and guiding system assembly a very time-consuming and expensive process, since due to these deformations and the high number of components, the connection between elements and modules is difficult, and highly qualified operators are required.
  • Another problem is that during the welding process a lot of sparks, fumes and noises are generated, creating a bad environment at working place. Also, to take into account, the high energy consumption in the welding process.
  • Figures 2a, 2b and 2c show different views of an assembly process of a truss known in the prior art with all the drawbacks thereof.
  • welded structures provide dimensions out of tolerance due to poor raw materials and archaic manufacturing process.
  • the assembly of guide supports for supporting and positioning the guiding system of the escalator/moving walkway takes several hours due to adjustments required.
  • the assembly of the guiding system takes another big amount of time due to a high precision required, since ride quality of the escalator/moving walkway highly depends on this guiding system.
  • Document EP2117747 discloses a method for clinching thick metal workpieces and the use of a clinching tool.
  • the invention relates to a method for the production of a load-bearing structural steel connection.
  • a clinching connection is formed by a male die and a female die using local deformation, and it connects two metal workpieces.
  • the metal workpieces are placed on top of each other on a processing surface of the female die and aligned.
  • the male die is applied and lowered into the two metal workpieces until the clinching connection is formed by plastic deformation.
  • the die is configured in a rotationally symmetrical manner with regard to the rotational axis thereof and has a conically shaped transitional region tapering at an angle in the lowering direction of the die.
  • Document WO2011048437 discloses a truss construction for a passenger conveyor.
  • the invention relates to a truss construction for a passenger conveyor comprising at least one self-supporting element.
  • the self-supporting element which is a roller molded element, extends in a conveying direction of the passenger conveyor and is formed with at least one rail portion for guiding step chain rollers and/or step rollers.
  • Document US2009/0050443 discloses a travelator, moving ramp or escalator for transporting passengers, and it comprises conveyor mounted on a frame that is supported on a fixed structure.
  • the frame comprises a number of mutually identical profiled metallic bodies joined together end to end one after the other and containing coupling, supporting and/or guide elements integrated in the profiled metallic body of solid material.
  • Document US2013/0228414 discloses an escalator or a moving walkway which includes a support structure and a soffit plate.
  • a first side edge region of the soffit plate is fixedly connected with the support structure.
  • the soffit plate is biased between the first side edge region and a second side edge region, which is opposite the first side edge region, by a predetermined biasing force.
  • the second side edge region is fixedly connected with the support structure, wherein through the maintenance of the biasing force a stiffness of the support structure is increased and in operation of the escalator or the moving walkway the output of noise is reduced.
  • Document EP2527283 discloses a support, a module to be placed on the support, and a transport system for displacement of people/goods modernized with the module and a modernization method of transport systems for displacement of people/goods.
  • the support has: fixings to fix the support to a bearing structure of the transport system, horizontal tie plates to support and horizontally place the module, lateral tie plates to support and laterally place the module, longitudinal tie plates to support and longitudinally place the module.
  • the module has positioning and verification equipment to place the module maintaining within tolerances the system lines of the transport system.
  • the transport system has: a support and an entrance/exit/central module on an entrance/exit finished floor/in a central section.
  • Document US6685002 shows a method of modernizing an escalator using modular components.
  • the mechanical and electrical parts of an existing escalator are removed, leaving only the structural truss framework and cross members as well as external parts, such as external panels, that interface with the building.
  • a single module is placed at the top of the escalator and another module at the bottom.
  • a plurality of incline modules are placed in the central inclined part of the escalator, at each cross member.
  • Document US2002/0175039 discloses a support structure for an escalator, which includes a bottom landing, a top landing, and a rise that interconnects the bottom and top landings.
  • An improved truss design comprised of steel modules that are stamped or bent is used to form the rise, the top landing, and the bottom landing.
  • the modules have closed sides, which increases the strength and stiffness of the truss while also providing the enclosure for internal escalator components.
  • the modules are either formed as a single piece or formed from multiple pieces that are welded or fastened together. The modules are then secured to each other to form the rise, the top landing, and the bottom landing.
  • the present invention provides an advantage with respect to the current modular trusses for escalators and moving walkaways, providing a modular and accurate truss, which reduces the number of components and saves time in the escalator or moving walkway assembly line.
  • This truss comprises three independent modules which are joined together in a complex structure. These modules are an upper module, a central module, and a lower module.
  • Each module comprises a first side, a second side, which is opposite to the first side, and a soffit plate placed between both sides.
  • Each side of the modules has in turn at least a metal sheet, and a plurality of vertical guide supports placed at the inner surface of the metal sheets, configured for supporting and positioning the guiding system of the escalator/moving walkway. Additionally, the vertical guide supports provide an additional rigidity to the sides of the modules.
  • These vertical guide supports may be integral to the metal sheets, and therefore they will be manufactured by press forging, stamping or bending the metal sheets, or on the other hand, the vertical guide supports may be independent from the metal sheets and they will be joined to the metal sheets by cold joining techniques.
  • these metal sheets are steel sheets, and preferably AHSS ("Advanced High Strength Steel”) sheets, and they may be laser-cut sheets, folded sheets, stamped sheets or bended sheets.
  • AHSS Advanced High Strength Steel
  • the modules of the escalator/moving walkway have a plurality of crossbars between both sides, each crossbar placed between a pair of opposite vertical guide supports, preferably perpendicularly to both sides.
  • the upper module and the lower module are joined to the central module by means of at least a joining bended plate made of metal placed at the ends of said upper and lower modules.
  • This joining plate is also used as support for the guides support in the transition areas between upper and central modules, and lower and central modules.
  • Another object of the invention is a method of assembling an escalator/moving walkway modular truss as disclosed in claim 10 of the present application.
  • the first stage of the method is an assembly of a first side and a second side opposite to the first side, for each one of the three modules of the escalator/moving walkway.
  • the assembly of each side of the modules includes a cold forming of metal sheets, and a cold joining of the soffit plate to the sides of each module.
  • the assembly between different parts is not made by welding, but by cold joining technologies, such for example, clinching, bolting, riveting or even means of hybrid solutions including adhesives.
  • the truss plays an additional role, besides of the structural one, and thanks to its good dimensional tolerances it is now able to support and position the whole guiding system of the escalator or the moving walkway.
  • the assembly method can be considered environmentally friendly.
  • the method includes a cold joining of a plurality of crossbars between both sides of the modules, placing each crossbar between a pair of opposite vertical guide supports, preferably perpendicularly to both sides.
  • the assembly of the upper module and the lower module to the central module is made by the cold joining of joining bended plates to the ends of the modules.
  • the cold joining in this case is clinching.
  • the method object of the present invention reinforce the area and improve the strength in this transition point, due to the substitution of welding by cold joining technologies. Again, since this joint is made by cold joining technologies instead of welding, an important reduction in the energy consumption is also performed.
  • the cold joining includes a method which may be clinching, bolting, riveting, using adhesives, and any combination of any of them.
  • one of the main advantages of the present method over the prior art is to replace an archaic and obsolete manufacturing process depending on high skilled welders, by a fully automatic process.
  • Most of cold joint technologies can be easily automated ensuring a high degree of repetitiveness instead of the current process, in which it is not possible to achieve the same final result in two theoretically identical escalator or moving walkway trusses.
  • this is an environmental friendly and sustainable manufacturing method, and it allows a reduction in the number of components and in the number of assembly stages that result in a more cost-effective truss for escalators/moving walkways.
  • One object of the present invention is an escalator/moving walkway modular truss.
  • the modular truss has an upper module 1, a central module 2, and a lower module 3.
  • each module 1,2,3 has a first side 4 and a second side 5 which is opposite to the first side 4, and a soffit plate 6 placed between both sides 4,5.
  • each side 4,5 of the modules 1,2,3 comprises in turn at least a metal sheet 7, and a plurality of vertical guide supports 9 placed at the inner surface 8 of the metal sheets 7, these vertical guide supports 9 configured for supporting and positioning the guiding system of the escalator or moving walkway.
  • an output cladding for the escalator/moving walkway would not be necessary due to the configuration and shape of the metal sheets 7.
  • each side 4,5 of the modules 1,2,3 may be formed by a single metal sheet 7, or by a plurality of metal sheets 7 joined together by cold joining technologies, forming a longer sheet.
  • the metal sheets 7 are steel sheets, and preferably AHSS ("Advanced High Strength Steel”) sheets, and they are selected between folded sheets, stamped sheets and bended sheets.
  • AHSS Advanced High Strength Steel
  • the vertical guide supports 9 are integral to the metal sheets 7. According an alternative embodiment of the invention, the vertical guide supports 9 are independent from the metal sheets 7, i.e., they are originally manufactured separately and independently from the metal sheets 7, and are joined to these sheets 7 by cold joining techniques, as shown in figure 4 .
  • Each module 1,2,3 has a plurality of crossbars 10 between both sides 4,5, and each crossbar 10 is placed between a pair of opposite vertical guide supports 9, preferably perpendicularly to both sides 4,5.
  • These crossbars 10 improve the rigidity of the assembly, enhancing the structural behaviour of the modular truss.
  • the upper module 1 and the lower module 3 are joined to the central module 2 by means of at least a joining bended plate 11 made of metal, which is placed at the ends of said upper 1 and lower 2 modules.
  • Figure 6 shows an upper module including these joining bended plates 11 according this embodiment.
  • the truss has a joining bended plate 11 placed at the end of each side 4,5 of the upper module 1 and the lower module 3. These joining bended plates 11 have the same height as the sides 4,5.
  • Figure 7 shows an upper module including these joining bended plates 11 according this alternative embodiment.
  • Another object of the present invention is a method of assembling an escalator/moving walkway modular truss formed by an upper module 1, a central module 2, and a lower module 3.
  • the method includes an assembly of a first side 4 and a second side 5 opposite to the first side 4 for each module 1,2,3, and attaching a soffit plate 6 between both sides 4,5 of each module 1,2,3. Later, the three modules 1,2,3 are assembled together.
  • the assembly of each side 4,5 of the modules includes first a cold forming of metal sheets 7, and then a cold joining of the soffit plate 6 to the sides 4,5 of each module 1,2,3.
  • the metal sheets 7 may be formed by means of laser-cutting, folding, stamping or bending.
  • the method of the present invention includes a cold joining of a plurality of crossbars 10 between both sides 4,5 of the modules 1,2,3.
  • Each crossbar 10 is placed between a pair of opposite vertical guide supports 9, preferably perpendicularly to both sides 4,5 of the modules 1,2,3.
  • Different embodiments of the method may include the forming of a single metal sheet 7, or alternatively, the joining of a plurality of metal sheets 7 by means of cold joining technologies forming a longer sheet.
  • the assembly of the upper module 1 and the lower module 3 to the central module 2 is made by a cold joining of bended plates 11 to the ends of the modules.
