Definitions

  • the invention relates to a moving walk according to the preamble of claim 1.
  • a moving walk is off US2007 / 036626 A1 disclosed.
  • the pallet band of a moving walk can be entered via access areas that connect to the two deflection areas.
  • Moving walks usually have due to the construction of their deflection on a large starting height of their entrance areas. So that the users do not have to run over a too large or too long ramp to the starting height, a pit is provided in the ground at least in the deflection. In these pits, the largest part of the deflection can be sunk, so that the pallet band can be entered almost at ground level.
  • the pallet belt usually has two link chains serving as traction means, between which the traveling platform pallets are arranged.
  • the abrupt change of direction of the moving pallets in the turning areas can lead to an uneven running of the entire pallet band.
  • the proposed turning region of the pavement pallets requires separate tracks of the leading rollers to the trailing rollers of a pavement pallet to control the passage of each pavement pallet through the turning area. As a result, the overall width of the moving walk is increased or the conveying width of the pallet band is limited.
  • Object of the present invention is to obtain a flat-building moving walkway, which has a quiet ride, which builds slim in relation to the width of its pallet band and the pallet band components are moderately stressed in the deflection.
  • each of the pavement pallets includes at least one body extending continuously between the traction means. Under the feature continuously extending body is a body to understand that extends without interruption between the two traction means, so is self-supporting and not just a local reinforcement of the pavement pallet serves. A continuously extending body does not necessarily have may be one piece, but may also consist of several assembled components.
  • the main body has a base surface for attachment of at least one Trittelements, wherein the base length of the base surface in the intended direction of travel of the moving pavement pallet extends and the width of the base surface extends orthogonal to the intended direction. Due to the articulated connection to an immediately following moving pavement pallet, a pivot axis extending in the width is defined for the base body. This pivot axis is arranged in a plane containing the base surface or above the side of this plane facing away from the base body. Furthermore, the base body along its width on a base body cross-section, the geometric center of gravity is arranged below the base surface.
  • the basic bodies are articulated to each other by means of the traction means, wherein the traction means can have the articulation points which include the pivot axes.
  • a pavement pallet By this body with high scheduled pivot axis in the plane of the base surface or above the base surface, a pavement pallet can be created, the tread element can be deflected when circulating in the deflection on the pitch circle of the Umlenkkettenrades or even on a smaller circular path than the pitch circle. Regardless of whether a Umlenkkettenrad without compensation of the polygon effect or a Umlenkkettenrad according to the EP 1 876 135 B1 is used with a compensation of the polygon effect can be reduced even more by the basic body according to the invention, the starting height between serving as a foundation or foundation ground and the tread element located in the entrance area.
  • the main body may have a width extending body cross-section with an outer contour, which is adapted to the position of the pivot axis of the body, and based on each existing spaces of the deflection, by the outer contours of the same shape body cross sections of an immediately preceding and immediately following, pivoted in the deflection basic body the pallet band is limited.
  • the main body has a basic body cross-section extending over its width, which has the highest possible moment of resistance in terms of bending and torsion of the basic body, without obstructing the deflection of the moving-platform pallets in the deflection region.
  • the body cross-section is preferably triangular or trapezoidal.
  • the base height of the triangular or trapezoidal body cross section is 0.5 to 2.5 times the base body length of the base surface.
  • a particularly good matching of the basic body cross section to the existing space in the deflection region is given when the basic body height of the triangular or trapezoidal basic body cross section is 0.65 to 1.5 times the basic body length of the base surface. The larger the ratio of the main body height to the main body length, the further the geometric center of gravity of the main body cross-section is arranged away from the base surface.
  • the triangular or trapezoidal body cross-section preferably has an internal angle between 35 ° and 85 °. This inner angle lies between a first side limb adjoining the base surface and a second side limb adjoining the base surface, wherein the side limbs are arranged tapering starting from the base surface.
  • an internal angle of 50 ° to 65 °.
  • the two side legs can be designed differently long. But they can also be arranged mirror-symmetrically to a central longitudinal plane which extends in width and orthogonal to the base surface and the base surface cuts in the middle. Due to the mirror-symmetrical arrangement, the main body can be inserted into the pallet band without regard to the running direction.
  • the two side legs must be starting from the base surface, not necessarily straight, they may also be concave or convex.
  • the widthwise extending side surfaces of the side legs and / or the base surface may have recesses.
  • the main body can be cast, for example, or made of an extruded profile.
  • the base body is made of a metal sheet.
  • the sheet may be, for example, aluminum, steel, brass, copper, bronze or stainless steel.
  • the settlement of the body is first cut or punched out of the sheet, which also equal to the recesses can be made. If the development is punched, their recesses can be provided with circumferential collar, and other areas are reinforced by beads. Thereafter, the triangular or trapezoidal body cross-section can be formed by means of extending parallel to the width of the base surface extending bends.
  • the widthwise extending sheet metal end edges of the above-described body made of sheet metal may be arranged overlapping each other and having an interconnected area.
  • Blechendkanten are all known types of welded joints, but also a crimping of Blechendkanten or a compound thereof by clinching. Since the base body is a bending support and, when used as intended, its base surface assumes the function of an upper belt of the bending beam, the area of the triangular or trapezoidal cross-section which is farthest from the base surface serves as a lower belt. Due to the trapezoidal or triangular cross-section of the body of this lower chord is significantly shorter than the upper chord.
  • the arrangement of the interconnected Blechendkanten in the region of this lower chord is particularly advantageous because the overlapping of Blechendkanten at this point a load-bearing material accumulation is created.
  • the side legs and / or the sheet metal end edges of the main body can also be connected by further parts such as frames, intermediate plates and the like.
  • the widthwise extending sheet metal end edges of the main body can also protrude into the inside of the main body to increase, for example, the dimensional stability of the base surface.
  • the widthwise extending Blechendkanten are arranged in the base surface.
  • At least one tread element can be fastened to the base body, wherein the tread element length extends analogously to the base body length of the base surface in the intended running direction of the moving walkway pallet. If the basic body length of the base surface corresponds to 0.6 to 0.95 times the tread element length of the at least one tread element to be fastened, a meshing overlap can be created between the tread elements. As a result, in the accessible area of the pallet conveyor, dangerous gaps that are narrowing over the accessible transport path of the moving walkway between adjacent moving walkway pallets can be avoided.
  • the base body can also be made of fiber composites and, for example, carbon fibers, aramid fibers and / or glass fibers.
  • a manufactured from fiber composites base body is wound or woven and therefore has a continuous outer contour with a triangular or trapezoidal cross-section.
  • the feature of a continuous outer contour is to be understood as meaning a tubular cross section of the basic body, wherein this tubular basic body may have exemptions and recesses.
  • Such a base body could be wound on a mandrel, wherein the recesses are produced by a suitable guidance of the fibers in the base surface and / or in the side surfaces of the side legs.
  • a large number of identical pavement pallets of the moving walkway according to the invention is arranged between the two traction means and articulated to each other via connection points with the traction means and thereby formed with the traction means a pallet strip.
  • pavement pallets arranged below one another are pivotable relative to one another about their pivot axes in the deflection regions.
  • Each of these moving pavement pallets contains at least one main body extending continuously between the two traction means of the pallet strip.
  • the main body has a base surface for attachment of at least one Trittelements, wherein the base length of the base surface in the intended direction of travel of the moving pavement pallet extends and the width of the base surface extends orthogonal to the intended direction.
  • each traveling platform pallet comprises at least one tread element which is fastened on the base surface of the basic body.
  • the pallets described above can be used not only in new, flat-building moving walkways, but also in conventional driving platforms with pits.
  • an old moving walkway can also be modernized and its running rails and deflection areas optionally adapted to the new pallet band.
  • the at least one tread element may have projections formed on the tread elements, which projections project into the base body through recesses in the base surface after the tread element has been placed on the base surface.
  • the at least one tread element can be fastened to the base body by at least one of the following fastening options, such as by caulking or riveting the projections, by means of screws, by means of clinching or by means of an adhesive.
  • Particularly suitable adhesives are pasty or liquid one-component adhesives / sealants based on silane-modified polymers which crosslink by atmospheric moisture to form an elastic product. These are used, for example, in body and vehicle construction, wagon construction and container construction and in metal and apparatus engineering.
  • a particularly simple fastening variant of the tread plates on the base body is that on at least one tread element projections are formed which protrude after placing the Trittelements on the base surface by recesses in the base surface and the tread element is fixed by means arranged on the projections spring washers on the base body.
  • the position of the recesses described above in the side surfaces of the side legs is matched to the position of the projecting through the base surface projections.
  • the size of the recesses is matched to the diameter of the spring discs, the projections can be fitted through the recesses through the spring discs.
