Definitions

  • the invention relates to a method for modernizing an existing escalator or an existing moving walk.
  • Escalators and moving walks are widely used and installed in many types of buildings, including commercial buildings, public transit stations, and airports.
  • the escalators and moving walks are used to move people quickly and efficiently from one floor to another. Escalators and moving walks usually stay in use for years, and in many cases for decades if properly maintained. Often the escalator or moving walk is manufactured at the same time as the building and is already incorporated into the building during the construction phase. Most escalators and moving walks are not simply offered as pre-defined mass-produced goods, but are individually adapted to the needs of the building owners and building users or the design of the building. As with all mechanical devices, however, the moving parts of the escalator or moving walk in particular wear out over time and must be replaced. Furthermore, the official regulations such as the European standard EN 115 are also changing.
  • the object of the present invention is to provide a simplified method for modernizing an existing escalator or an existing moving walk.
  • the procedure described above eliminates the main cause of the necessary, extensive adjustment work on the new components to be added.
  • These are caused in particular by the existing cross struts, which are usually arranged between the forward and the return of the circulating conveyor belt (step belt for escalators, pallet belt for moving walks).
  • the existing cross struts can have very different dimensions depending on the manufacturer and therefore influence the distance between the running rails of the flow and return.
  • the new cross struts to be added are ideally matched to the new components to be added, so that the new components such as running rails, running rail supports or frames, deflection modules, tensioning slides and the like are no longer adapted to the dimensions and position of the existing cross struts in the existing framework need to be adjusted.
  • the truss side parts of most of the existing trusses are, apart from the cross struts and at the end connected by the support bracket, only through a floor structure and thus form a U-shaped cross-section, open at the top for the other components of the escalator or moving walk.
  • the particular obstacle to removing existing cross struts is that the existing cross struts cannot simply be cut out of the existing framework, because they mutually support the two framework side parts of the existing framework stored in the building and thus give the existing framework a high degree of rigidity and Stability. Since the existing truss is like a bridge, even while the modernization process is being carried out, it is only supported on both of its front sides in the building, it must be prevented that dangerous situations arise.
  • the two end faces are those areas where the support brackets are arranged as an interface between the framework and the building.
  • the access areas through which the users enter or exit an escalator or moving walk are arranged there.
  • the framework between the two end faces can be additionally supported by means of intermediate bearings. But this is enough not enough to keep the framework stiff and stable in the absence of cross braces.
  • the statics of the truss is designed for the rigidity and load-bearing capacity of its vertically standing truss side parts. Due to the dead weight of the truss and forces acting on the truss such as point loads, shocks, vibrations and the like, there is a risk that the truss side parts could tilt to the side due to the lack of cross struts and then the truss could collapse or at least plastically deform. A collapsed or deformed framework is completely unusable and could no longer be repaired or straightened.
  • a dimensionally stable and rigid framework is also an advantage that should not be underestimated while the modernization process is being carried out.
  • the cleared truss may only be used like an assembly platform if the safety of the assembly staff is guaranteed. If its dimensional stability is guaranteed, material can safely be transported on the existing framework to its installation location.
  • the cross struts are replaced sequentially to stabilize the two truss side parts.
  • the truss side parts are connected to each other in a decreasing manner with existing cross struts and increasingly with new cross struts in a stabilizing manner, with the new cross struts being spaced from the floor structure and connecting the two truss side parts being arranged in the framework.
  • one cross brace is preferably replaced after the other.
  • two or more cross struts can be replaced at the same time. Another possibility is that every second existing cross strut is removed first and, after its removal, the free areas are each provided with a new cross strut. Then the remaining existing cross struts are removed and the free areas are then provided with new cross struts.
  • the existing Cross struts at least one stabilization device for stabilizing the two truss side parts attached to the existing truss. This connects the truss side parts to one another in a stabilizing manner at a point spaced apart from the floor structure of the existing truss.
  • the existing cross struts can be removed and then new cross struts inserted. After inserting the new cross struts, the at least one stabilization device is removed.
  • a simple stabilizing strut for example, can be attached to the truss side parts as a stabilizing device. This can preferably be fastened to the truss side parts by means of releasable connecting elements such as clamping jaws, screws, socket pins, cotter pins and the like. It is sufficient if it supports the truss side parts against each other, the stabilizing strut does not have to be able to transfer large forces.
  • the stabilizing strut must, however, be both tensile and pressure-resistant, that is to say that it can withstand the maximum tensile forces and compressive forces occurring at its fastening point without tearing or kinking.
  • the position of the new cross struts in the existing framework is determined from the space required for the modernization components to be newly inserted and in relation to the height of the framework side parts. This ensures that there is sufficient space between the new cross strut and the floor structure for the new components to be inserted, in particular for the return of the step belt or pallet belt.
  • the new cross struts should not be placed too far from the floor structure between the truss side parts so that too many adjustments are not necessary for the new balustrade base, the position of which is also based on the position of the step band or pallet band in the truss.
  • the position of the new cross brace is preferably specified as a distance from the upper chords of the existing truss side parts in the direction of the lower chords of the existing truss side parts as a positioning instruction.
  • it is sufficient to simply measure and mark the distance for example on truss uprights of the existing truss side parts. These trusses connect its upper chord with its lower chord.
  • the new cross strut can be clamped to the truss uprights using screw clamps and then welded, riveted or screwed onto them.
  • the cross brace should be aligned as horizontally as possible. A very precise alignment of the cross struts, for example by means of a spirit level, is not absolutely necessary, however, since the precise alignment only takes place with the insertion of so-called frames.
  • the existing cross struts are welded to a first side surface of truss uprights of the truss side parts.
  • the existing cross struts can be removed quickly and easily by simply sawing them through on both sides and near the truss.
  • a small piece of the existing cross brace remains on each truss side part or on the truss frame. So that this piece does not have to be laboriously removed, the new cross brace can be attached to a second side surface of the truss.
  • a first deflection module with rail interfaces at a first end of the framework and a second deflection module with rail interfaces at a second end of the framework can be installed in the framework provided with new cross struts.
  • ends of the framework means the two end faces of the framework, which usually each have a support bracket via which the framework is supported in the structure.
  • the correct positions of the two deflection modules are determined as a function of a level adjoining the framework, for example the floor of a floor of a building, and the position of the new cross struts in the existing framework.
  • the deflection modules often also referred to as rail blocks, contain all the relevant components to deflect a step belt or pallet belt from its forward to its return. These are, for example, deflection guide rails with rail interfaces. Furthermore, the first deflection module has a tensioning slide with a deflection axis which is provided with deflection chain wheels. In addition to the rail interfaces, the second deflection module has a drive shaft with drive chain wheels, possibly also a drive motor with a gearbox for Driving the drive shaft.
  • So-called frames are fastened in the framework between the two deflection modules, which have fastening points for running rails or running tracks.
  • the running rails must be precisely aligned with the rail interfaces. This is achieved particularly precisely if an alignment device is arranged at the rail interfaces of the first deflection module and a targeting device is arranged at the rail interfaces of the second deflection module.
  • the alignment device has an alignment means, preferably a laser beam.
  • another alignment means for example a tensioned rope, a tensioned cord or a tensioned wire, can also be used, the sagging due to their own weight having to be taken into account when using them.
  • the alignment means is adjusted to the aiming device. Additional components to be inserted between the deflection modules, such as the frames to be inserted, can be aligned with this alignment means.
  • a frame assembly device or frame assembly jig is preferably available.
  • This frame mounting device is first equipped with a right frame and a left frame on the receptacles provided. Then the frame mounting device is placed on a new cross strut and then the frame mounting device is aligned on the alignment means of the alignment device by means of its own adjusting device. The frames, held in alignment by the frame mounting device, are then attached to the new cross brace. Finally, the bulkhead mounting device is removed from the new bulkheaded cross brace.
  • the new cross struts can be designed in such a way that they primarily have a stabilizing effect.
  • the frames can be attached additionally or only to the truss side parts, for example by means of connecting straps which are welded between the truss uprights and the frames.
  • Such, especially stabilizing cross struts can be dimensioned very small in terms of their cross-section and allow very slim constructions, which in each existing trusses.
  • the framework which is provided with new cross struts, frames and deflection modules, can now be completed with new running rails, drive components, control components, with a step belt or pallet belt, with cladding parts, balustrades and handrails for a modernized escalator or a modernized moving walkway.
  • the adjustment device of the frame assembly device can have two adjustment devices which are arranged distally from one another and which are supported on the new cross strut for the purpose of adjusting the assembly device.
  • the adjustment device also includes an alignment aperture with a bore or a rear sight with a groove. The diameter of the bore or the cross section of the groove are matched to the alignment means. If, for example, a laser beam of the alignment device is used as alignment means, then an alignment diaphragm with a bore is preferably used which has the beam cross section of the laser beam.
  • a rear sight with a groove, the cross-section of which is matched to the wire diameter is more likely to be provided.
  • the new cross struts and the frames can be inserted together.
  • the new cross brace which is built into an existing framework to replace an existing cross brace, is already provided with the ribs.
  • Frame-like formations are preferably formed on the new cross strut.
  • the new cross strut is cut in one piece from a sheet metal, the new cross strut having a central section formed by folds in a C-shape and at least two frame sections formed on the central section. At least fastening points for running rails of the escalator or the moving walk are formed on these frame sections.
  • At least one alignment diaphragm with a bore or a rear sight with a groove is formed on the aforementioned new cross strut. This is possible without any problems, as this is preferably worked out of a sheet metal using a laser cutting process or CNC punching process and the alignment diaphragm or rear sight can be cut out at the same time.
  • the diameter of the bore or the cross section of the groove are matched to the alignment means of the alignment device.
  • Figure 1 shows a schematic side view of an existing escalator 1 that connects a first floor E1 with a second floor E2. So that its most important components can be shown, the escalator 1 is the Figure 1 shown without side panels.
  • the escalator 1 has a framework 6 with two deflection areas 7, 8, between which a step belt 5, which is only partially shown, is guided circumferentially.
  • the step belt 5 has traction means 9 on which steps 4 are arranged.
  • schematically illustrated running rails 11 are also arranged, which extend between the two deflection areas 7, 8 and guide the step belt 5 in the forward and in the return.
  • a deflection axle 12 with deflection chain wheels 13 (only one visible) is rotatably mounted in the deflection area 8 of the On the second floor E2 there is a deflection shaft 14 with drive sprockets 15 (only one visible) which are driven by a drive 19.
  • the step belt 5 is guided around the chain wheels 13, 15 in both deflection areas 7, 8.
  • the drive 19 is controlled by means of a controller 20.
  • a handrail 3 is arranged on a balustrade 2.
  • the lower end of the balustrade 2 is connected to the framework 6 by means of a balustrade base 10.
  • the escalator 1 or its step belt 5 can be entered via the access areas 16, 17 present at both ends of the escalator 1.
  • the accessible areas of the access areas 16, 17 are floor covers 21, which each flush or evenly close the opening of the underfloor deflection area 7, 8 of the escalator 1 to the surrounding, accessible floor 18 of the floors E1, E2.
  • an existing moving walk 1 can also be present, with a pallet belt being arranged around the circumference instead of a step belt 5. Furthermore, the central part of a moving walkway arranged between the deflection areas has no gradient or only a slight gradient of up to 12%.
  • the framework 6 Due to its dimensions and its high weight, the framework 6 is also the component of an escalator 1 or a moving walk 1 that generates the most effort. Thus, its transport is expensive and, if necessary, walls in the existing building have to be partially demolished and large openings made in the building envelope to bring the new escalator 1 into the existing building. Therefore offers it is a matter of continuing to use the existing framework 6.
  • the existing escalator 1 or the existing moving walk 1 must first be dismantled with the exception of the existing framework 6.
  • the existing framework 6 is ideally used as scaffolding between the two floors E1 and E2 when the existing components of the escalator 1 or the existing moving walk 1 are dismantled.

  • the existing cross struts 39 mutually support the two truss side parts 31, 32 of the existing truss 6 stored in the floors 18 of the floors E1, E2 and thereby give the existing truss 6 a high degree of rigidity and stability.
  • the dimensions and the position of the existing cross struts 39 in the framework 6 are matched to the components of the existing escalator 1 that have already been removed. Since the existing framework 6 is like a bridge, is still supported on its two end faces 41, 42 in the building, a high level of instability of the existing framework 6 would result if the existing cross struts 39 were simply removed.
  • the existing cross struts 39 are then replaced by new cross struts 40 which are adapted to the parts of the modernized escalator 1 that are to be newly installed. This can be done, for example, in a first variant of the proposed method for modernizing an existing escalator 1 or an existing one Moving sidewalks take place in which existing cross struts 39 are sequentially replaced by new cross struts 40.
  • not all existing cross struts 39 necessarily have to be replaced by new cross struts 40, because it may be that existing cross struts 39 in the deflection areas 7, 8 have to be removed in order to have enough space for deflection modules 51, to be inserted there. 52 (see Figure 3 ) to create, which connect the truss side parts 31, 32 to each other in a stabilizing manner in these areas.
  • the position of the new cross strut 40 in the existing framework 6 can first be determined. This depends on the installation space required for the new modernization components to be inserted and must be set in relation to the height H of the truss side parts 31, 32. This can ensure that there is sufficient passage height X between the new cross strut 40 and the floor structure 37 for the new components to be inserted, in particular for the return of the step belt 5 or pallet belt.
  • the new cross struts 40 should not be arranged too far from the floor structure 37 between the truss side parts 31, 32 so that not too many adjustments for the new balustrade base (see FIG Figure 5 ) are necessary, the position of which is also based on the position of the step belt 5 or the pallet belt in the framework 6.
