Definitions

• the present invention relates to a passenger transport device, in particular an escalator or moving walk, and a method for arranging a passenger transport device at a place of use.
• Passenger conveyors such as escalators or moving walks are often used for the transport of large crowds. Escalators or moving walks are therefore often found in department stores, airports or underground stations.
• Such escalators or moving walks usually have a stable support structure in the form of a carrier, in which are arranged connected to a rotating band conveyor elements and rotate.
• this band is, for example, designed as a step band, in the case of a moving walk, for example, as a flat conveyor belt.
• This revolving belt is driven by means of a drive arranged in the carrier with a drive shaft around which the belt runs.
• a handrail is provided.
• the carrier Due to high loading forces, which occur during the operation of an escalator or moving walk and in particular act on the drive shaft, the carrier must be particularly stable in order to absorb and discharge these large forces.
• a passenger transport device in particular an escalator or moving walk, has conveying elements connected to a revolving belt and a drive for the conveying elements, wherein the drive has at least one motor, one transmission and a drive shaft operatively connected to the engine via the transmission, and wherein the conveyance elements connected to a circulating belt are guided over the drive shaft and are movable by means of the drive shaft.
• the passenger transport device further comprises a first carrier, in which the conveying elements connected to a circulating belt are arranged guidable, and a second carrier, in which the drive shaft of the drive is arranged, wherein the passenger conveyor device does not have a mechanical connection between the first carrier and the second carrier, which transmits to the first carrier a majority of the forces acting on the drive during operation by the conveyors connected to a circulating belt.
• the circulating belt is guided outside the first carrier by the guide via the drive shaft arranged in the second carrier.
• the second carrier on which substantially the forces which are caused during operation by the conveying elements connected to a circulating belt are substantially decoupled from the first carrier in terms of their power.
• These forces acting on the drive arise, for example, already by the weight of the usually inclined belt with conveyor elements.
• no component is present at all, which provides a mechanical connection between the first and the second carrier creates.
• a component for example for covering or lining or for alignment or adjustment or for guiding the band, this in any case does not serve to transfer substantial forces from the second carrier to the first carrier.
• the main part of the forces ie.
• the second carrier is thus advantageously mechanically decoupled from the first carrier, in particular such that at most a small part of the forces which act on the drive during operation due to the conveyor elements connected to a circulating belt first carrier is transmitted.
• a passenger transport device thus makes it possible for the first carrier, in which the band is arranged with the conveying elements, that is, for example a stepped belt and on which persons can be transported, to be designed to be particularly light and narrow, since the forces occurring only proportionally derived from this first carrier. Instead, the forces act essentially only on the second carrier in which the drive is arranged.
• Another advantage is a very easy accessibility and thus also exchangeability of the second carrier or the drive, since no carrier surrounding the drive is present as part of the entire passenger conveyor.
• the second carrier is spaced from the first carrier in or against a conveying direction of the passenger conveyor. Such a spacing can ensure that the forces acting on the second carrier act as little as possible on the first carrier, and that the space requirement in the width remains small.
• the passenger conveyor has no mechanical connection between the first carrier and the second carrier, which carries a weight of the second carrier, in particular with drive arranged therein.
• the second carrier has fastening means for attachment to and / or in a floor or floor element. This allows a particularly simple and effective attachment or anchoring of the second carrier, whereby the majority of the forces in the soil or the soil element can be derived.
• the second carrier together with the fastening means is set up such that the forces acting on the drive during the movement of the conveyor belts connected to a circulating belt are conducted essentially into the floor or the floor element.
• This can be achieved, for example, by a suitable design of the second carrier and appropriate placement of the fastening means.
• the first carrier can thus be substantially relieved of forces occurring during operation of the passenger transport device - apart from weight forces of the first carrier and components arranged therein.
• the second carrier has carrier elements which have a greater width and / or thickness than corresponding carrier elements of the first carrier.
• the second carrier can be performed much more stable than the first carrier.
• the second carrier may then be designed in its construction in terms of stability as the carrier of a conventional passenger transport device, for example. With steel support elements, while the first carrier is narrow and lightweight, for example. With sheets, is executed.
• a method according to the invention is used for arranging a passenger transport device, in particular an escalator or moving walk, at a place of use, wherein a first carrier, which is provided for guiding and arranging conveyor elements connected to a revolving belt, and a second carrier, which is arranged to be arranged therein a drive for the conveyor elements with a drive shaft, which is driven by at least one motor via a gear, and wherein the first carrier at a different time than the second carrier arranged at the site becomes .
• the two carriers are not arranged as a structurally connected unit, but separately and successively.
• An inventive method thus allows a particularly simple installation or a simple installation of a passenger transport device, in particular a passenger transport device according to the invention, since the individual carriers much easier or constructively different than the sole carrier of a conventional passenger conveyor.
• the second carrier is arranged at a distance from the first carrier in or against a conveying direction of the passenger conveyor.
• the first carrier with the second carrier is not connected to a component which provides a mechanical connection between the first and the second carrier and which a majority of the forces acting on the drive during operation by the conveyance elements connected to a circulating belt , transfers to the first carrier.
• conveying elements are inserted into the first carrier and connected to a circulating belt.
• the conveyor elements can be easily inserted into the already arranged carrier. A previous installation is not necessary.
• the second support is attached to and / or in a floor or a floor element. It is further advantageous if the second carrier is attached to and / or in the bottom or the bottom element such that when moving the conveyor belt connected to a circulating belt, the main part of the force acting on the drive forces in the soil or the bottom element is directed.
