Definitions
- the invention relates to a device for guiding and deflecting pallet belts of a moving walk.
- DE-A 22 52 1 34 shows a moving walk for passenger transport, in particular a flat moving walk for simultaneous transport in both directions, with an essentially endless chain-like strand guided around the horizontal axis and one or more drives actuating it. s).
- the essentially endless chain-like strand has on its outside plates or pallets arranged at predeterminable intervals and on its inside racks in which the drives engage directly and positively on both sides, the pallet strand being passable on both sides.
- toothed segments are provided with the drives on an endless flexible carrier, for example a chain or a belt.
- This moving walk is already provided with a low overall height, since the pallets can be deflected in the horizontal direction about a vertical axis, but here a disproportionately large amount of space is required in the plane.
- German utility model 201 00 833 an escalator or a moving walk is dealt with, with a step or pallet belt that is driven by drive elements that extend on both sides of the belt or in the middle under the belt and that rotate between a deflection wheel and a drive wheel, whereby the steps or pallets are driven at drive points on each drive element.
- the drive element is designed as a toothed belt which has blocks. One block each is connected to a step or pallet at the drive point.
- a common form of circulation has been chosen here, with the one that is usually used instead Link chains can now be used timing belts. Since usual revolving elements with the given necessary radii are used, it is not possible to reduce the overall height of the revolving elements.
- the aim of the subject matter of the invention is to provide a device for guiding and deflecting pallet belts of a moving walkway, in which the pallets can be deflected around a horizontal axis in the usual form and nevertheless bring about a reduction in the structural height of the rotating elements, for example in the range ⁇ 500 mm can be without disadvantages in passenger transportation.
- a device for guiding and deflecting pallet belts of a moving walkway with a low pallet circumferential height comprising a multiplicity of pallet strips in operative connection with one another, seen in the running direction of the pallet belt, of short length, several support elements which, over the width of the Seen pallet strips, are provided below the transport area of the pallet belt and several belt-like drive elements which are positively connected to the pallet strips outside the transport area.
- the drive elements are preferably positively connected to the pallet strips, at least profiles being provided on the pallet strip side, which engage in corresponding counter profiles in the area of the pallet strips.
- the drive elements are advantageously equipped with stiffening elements, such as steel fibers or the like.
- the entrainment elements are connected to the associated pallet strips, in particular by screwing, the fixing thereof being carried out in the invisible region of the pallet strips.
- the drive elements are not screwed to the entrainment elements, so that they can be guided flexibly around a deflection element, in particular a disc-shaped one, in particular in the deflection area.
- the profiles of the drive element are at least partially pressed out of the counter profiles, since different deflection radii are given. Since there is no relative movement between these elements in the course of the deflection of the drive elements and the entrainment elements, the profiles can be easily reconnected into the associated counter profiles in the course of the deflection.
- the pallet strips can either be continuous or composed of segments. Depending on the shape selected, the person skilled in the art will provide a corresponding number of drive and driving elements below the pallet strips.
- guide rollers are arranged in the end regions of the pallet strips and are provided in the return run on corresponding rail-like guides.
- FIG. 1 schematic diagram of a moving walk with low pallet
- Circulation height can be used, for example, in an airport terminal
- Figure 2 representation of pallet strips including support area in different views
- Figure 3 Individual part representation of the support area in different views
- FIG. 1 Schematic diagram of one of the deflection areas
- FIGS. 7 and 8 Continuous or segment-like pallet strips with associated drive elements.
- Figure 1 shows a schematic diagram of a moving walkway 1 with a low circumferential height of the area 2 intended for transport.
- the only indicated moving walkway 1 is - as will be explained in more detail in the following figures - designed in such a way that it is seen over substantial parts of the transport route, flat on the Level 3 of a floor can be built.
- Pits can only be provided in the drive area 4 and / or 5, if necessary, so that the drive elements, such as motors, gears or the like, can be accommodated there.
- FIG. 2 shows a schematic diagram of two pallet strips 6 with a relatively short length (a) when viewed in the direction of transport.
- the pallet strips 6 are provided analogously to the conventional pallets for moving walks with equivalent profiles 7 in the transport area. Only a partial area of the pallet strips 6 is shown.
- fastening elements 9 are provided for driving elements 10 only indicated here, which are described in more detail in the following figures.
- rollers 1 2 connected to the underside 1 1 of the pallet strips 6 are arranged at regular intervals and are operatively connected to the pallet strip 6 via bolts 1 3.
- Support elements 14 are provided in the scaffold body of the moving walkway 2, which are equipped on the track roller side with noise-damping tracks 1 5, in particular made of polyurethane, on which the track rollers 1 2 are supported.
- Figure 3 shows a partial view of one of the support elements 1 4 in an enlarged view.
- a pallet strip 6, a roller 1 2 and one of the bolts 1 3 and the guideway 1 5 can be seen.
- recesses 1 6 are formed, which serve to receive the bolts 1 3.
- the pallet strips 6 can - as with the conventional pallets - consist of die-cast aluminum. However, it is also conceivable to produce them from fiber-reinforced plastic, if necessary.
- FIG. 4 shows a schematic diagram of one of the deflection regions 17, formed by a disk-shaped deflection element which contains recesses 18 at predeterminable intervals.
- the driving element 1 0 and a belt-like drive element 20, which is equipped with corresponding profiles 21, are indicated.
- the driving element 10 is formed by a body with a T-shaped cross section with an elongated leg 19, the region 22 facing the drive element 20 being provided in a rounded shape.
- the other leg 23 of the driving element 1 0 engages in the associated recess 1 8 of the disc-shaped deflection element 1 7. Via the fastening elements 9 of the respective pallet strip 6, the responsible driving element 10 is firmly connected to the pallet strip 9 outside the drive element 20.
- the profiles 21 of the Drive element 20 are positively guided in corresponding counter profiles 24 of the respective pallet strip 6. Since there is no fixed connection between the pallet strip 6 and the driving element 1 0, the profiles 21 can be at least partially removed from the counter profiles 24 in the course of the deflection process around the deflection element 1 7. Since there is no relative movement between the drive element 20 and the entrainment elements 1 0, the profiles 21 are also tied back into the counter profiles 24 when leaving the deflection element 1 7.
- FIG. 5 shows a further partial view of the connection area between the pallet strips 6, the driving element 10 and the drive element 20.
- Steel fiber inserts 25 are indicated as tension members for the drive element 20.
- the base area 26 of the moving walk is also indicated. It can be seen that the drive element 20 is provided outside the fastening elements 9 and thus there is no fixed connection between the pallet strip 6 and the driving element 10.
- Each pallet strip 6 has laterally provided guide rollers 27, which, however, are not effective in the transport area, but rather roll on corresponding guide tracks in the non-guided return run.
- Figure 6 shows a possible drive 28 for the pallet belt.
- An electric motor 29 is shown which has a gearwheel 30 on the drive side. With the disk-like deflection element 17, a further gear wheel 31 is provided, but with a significantly larger number of teeth. In this way, the high output rotational speed of the electric motor 29 can be reduced to such an extent that the pallet strips 6 can only be transported in the direction of travel so quickly that problem-free transport of people is possible.
- the electric motor 29 is dimensioned so that it remains within the overall height of the pallet strips 6. If this is not possible, a pit would as shown in Figure 1 - are provided for the drive 28.
- a correspondingly designed toothed belt 32 provided with reinforcing elements extends between the toothed wheels 30, 31. If a toothed belt 32 is not desired, a mechanical transmission between the electric motor 29 and the deflection element 17 can be provided if necessary.
- FIGS. 7 and 8 show alternative representations of pallet strips 6.
- FIG. 7 shows a continuous pallet strip 6 in operative connection with a plurality of drive elements 20 arranged underneath it.
- the pallet strip 6 according to FIG. 8 is formed by a plurality of segments 6 ′ which are connected to one another, but not each segment 6 'a drive element 20 is assigned.
