Definitions
- the invention relates to a drive system for escalators and moving walks with at least one drive chain and spaced-apart deflection elements for the drive chain, the drive chain being connected via bolts to steps or pallets of the escalator or moving walkway, which is positioned between two joints of the drive chain and each with are provided with a roller.
- Escalators that are used as heavy-duty escalators outdoors, for example in subway shafts or the like, are also particularly known.
- link chains are usually used as drive elements, with the step rollers being provided outside the drive chain in view of the larger drives.
- the design effort given here is considerably greater than with a so-called department store escalator, which means that the overall width of the heavy-duty escalators must also be larger than with a department store escalator.
- DE-A 175681 3 shows a roller-step chain connection of escalators, in which the step pin is provided between two joints of the drive chain.
- the rollers should preferably be provided between two joints of the drive chain inside or outside the inner link plates or outer link plates.
- the object of the invention is to further develop the drive system for escalators and escalators described in the generic part of the first claim so that the construction effort, in particular the heavy-duty escalators or escalators, is simplified, so that, if necessary, identical or related parts can be used ⁇ without this having an adverse effect on the different driving forces.
- Today's state-of-the-art chain pitches are around 133 mm for conventional step or pallet tread lengths of around 400 mm.
- the chain pitch can be increased in two stages. Given the same conditions (step or pallet tread length of about 400 mm), further possible chain divisions would be once 200 mm and once 400 mm, i.e. two links per step or pallet or one link per step or pallet.
- the roller can be provided between the joints of the drive chain in both the department store and the heavy-duty escalator, so that in both systems it is possible to fall back on evenly constructed drive chains.
- the installation space of the so-called heavy-duty escalators / heavy-duty escalators can thus be reduced, which ultimately also results in a reduction in costs.
- AC asynchronous motors are usually used, which are operatively connected to the frequency converter, so that the motor can be controlled such that it is not constant Rotates speed, which then, if necessary, acts in a corresponding manner on the respective deflection element, including a gear.
- the varying chain speeds that are present at the chain inlet are largely compensated for by this proposal, or an adjustment is made to it, so that the shocks in the system that have been present up to now are largely compensated for.
- This circumferential link chain preferably consists of plain bearing material and is dragged along by the step chain.
- the advantage is the flat support of the protective roller in the respective support element of the relief device, which is exposed to very little wear without relative movement, and compared to conventional solutions, as well as the relatively large flat sliding area of the element, which enables sliding friction at a low surface pressure level.
- Fig. 1 schematic diagram of an indicated deflection element, in particular a sprocket, for the drive chain of an escalator
- Fig. 2a drive chain for heavy duty escalators with external
- FIG. 3 sketch of a relief device for the
- FIG. 4 schematic diagram of a polygon-loaded deflection area for the
- the drive system 1 shows the drive system 1 according to the invention as a schematic diagram, including a deflection element 2 designed as a chain wheel and a drive chain 3.
- the drive chain 3 contains a plurality of interconnected plates 4 which are connected to one another via joints 5. About halfway between the joints 5 extend rollers 6, which are operatively connected via step bolts 7 to the steps of an escalator, which are not recognizable here.
- the deflection element 2 has chain teeth 8, which are adapted to the pitch of the drive chain 3 in a correspondingly reduced manner. In this example, a step tread length of 400 mm should be assumed.
- the chain teeth 8 are provided on the chain side with recesses 9, which serve to receive the joints 5, while the rollers 6 are positioned in corresponding recesses 10 of the deflection element 2.
- recesses 9 which serve to receive the joints 5, while the rollers 6 are positioned in corresponding recesses 10 of the deflection element 2.
- Fig. 2a shows a drive system 1 1, which represents the prior art and is used for a heavy-duty escalator. Steps 12 can be seen, which interact via stepped bolts 13 with rollers 1 5 provided outside the drive chain 14. The stepped bolts 13 extend through the joints 16 of the drive chain 14. Assuming a step length of approximately 400 mm, the chain pitch is 133 mm, so that each link 12 has three links in the drive chain 14.
- FIG. 2b shows a drive chain 3 with a 200 pitch, ie two links of the drive chain 3 are provided for each step
- FIG. 2c shows a drive chain 3 with a 400 pitch and internal rollers 6, which are positioned between the joints 5 of the drive chain 3.
- the drive chain 3 including joints 5 and inner rollers 6 can be seen.
- the joints 5 are of gentle rollers
- the relief device 17 is arcuate in cross-section and represents a so-called relief curve, which is operatively connected to a rotating link chain 20.
- Fig. 4 shows a schematic diagram of the drive area 23 of a moving walk.
- the deflecting element 2 and the drive chain 3 containing a plurality of links 4 can be seen.
- the teeth 8 of the deflecting element 2 are only indicated, but can also correspond structurally to those according to FIG. 1.
- the drive motor is provided with the reference numeral 24 and, if necessary, is operatively connected to a transmission, not shown.
- the connection between the drive motor 24 and the deflection element 2 is ensured by a drive member 25.
- the running direction of the drive chain 3 or the deflection direction of the deflection element 2 is indicated by arrows.
- the at the arrival of the Drive chain 3 in the deflection element 2 given polygon effects are now reduced in that the speed of the deflection element 2 is superimposed on a different speed, so that the deflection element 2 rotates at a non-constant speed which corresponds to the mathematical function of the drive chain 3 when entering the deflection element 2 largely corresponds. This minimizes the shocks and speed fluctuations that occur in the overall system.
- the superimposition is brought about by the fact that a frequency converter 26 is operatively connected to the drive motor 24, which drives the drive motor 24 in such a way that it rotates at a non-constant speed and transmits this non-constant speed via the drive member 25 to the deflection element 2 in a superimposed manner becomes.
- a plurality of control parameters can be stored in a control device 27, which contain basic patterns of already existing escalators or moving walks, so that these basic settings can be used in standard designs.
- the comfort is to be increased, it is possible to determine the phase position of the deflection element 2 by means of a sensor 28 and to make this available to the control device 27.
- Another parameter can be the rotational speed of the drive chain 3, which is detected, for example, by a further sensor 29 and these measured values are also made available to the control device 27.
- the frequency converter 26 can now be supplied with electrical measured values in such a way that the drive motor 24 is continuously controlled, for example, at different speeds of the drive chain 3 can.
