Definitions
- the invention relates to a basic body of a moving pavement pallet, a pavement pallet and a moving walk with a pallet belt, which is guided circumferentially between two deflection.
- 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. These link chains are guided in the deflection over Umlenkketten impart.
- EP 1 876 135 B l discloses solutions to eliminate the polygon effect at sprocket diameters, which fall below the required diameter.
- WO2006 / 003238 A2 proposes a flat-building moving walkway, in which the moving-platform pallets are deflected in a turning area, instead of providing deflection areas with the conventional deflection of the moving-platform pallets by 180 °.
- the pavement pallets In order for the pavement pallets to be diverted to have a sufficient payload at an intended width of the pallet band, they are very long in relation to the intended direction of travel.
- 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 base body has a base surface for fastening at least one tread element, wherein the base length of the base surface extends in the intended running direction of the moving pavement pallet and the width of the base surface extends orthogonally to the intended running 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.
- 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.
- the main body can 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, in the deflection pivoted body of the pallet strip 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 main body, without obstructing the deflection of the moving-platform pallets in the deflection region.
- 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 sheet metal end edges of the above-described body made of sheet metal may be arranged overlapping each other and having an interconnected area.
- all known types of welded joints, but also a flaring of the sheet metal end edges or a compound thereof by means of clinching are suitable.
- 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 area of this lower chord is particularly advantageous because the overlapping of the Blechendkanten at this point a load-bearing material accumulation is created.
- the side legs and / or their sheet metal end edges of the main body can also be connected by other parts such as frames, intermediate plates and the like.
- Each of these moving pavement pallets contains at least one main body extending continuously between the two traction means of the pallet strip.
- the base 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 the
- 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 as 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 laying the Trittelements on the base surface by recesses in the base flat and the tread is attached 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 adapted 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 ,
