Passenger conveyor

description

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.

State of the art

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. In the case of an escalator, 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. Furthermore, usually a handrail is provided.

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.

In escalators or moving walks for a particularly narrow space, for example. In tunnels that lead to underground stations or even to the arrangement of several escalators or moving walks next to each other, a particularly narrow design may be desired or even required.

In order nevertheless to be able to provide the widest possible area of use for persons, the wearer of the escalator or of the moving walk must, in particular, on the side surfaces be formed narrow. However, this leads to problems with regard to the forces occurring on the drive shaft, which can then no longer be derived by the carrier.

It is therefore desirable to provide a passenger transport device in which a lightweight and / or narrow carrier can also be used.

Disclosure of the invention

According to the invention, a passenger transport device and a method for arranging a passenger transport device having the features of the independent patent claims are proposed. Advantageous embodiments are the subject of the dependent claims and the following description.

A passenger transport device according to the invention, 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. In particular, the circulating belt is guided outside the first carrier by the guide via the drive shaft arranged in the second carrier.

In other words, in other words, 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. Preferably, no component is present at all, which provides a mechanical connection between the first and the second carrier creates. However, should a component be used, 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. more than 50%, preferably more than 75%, most preferably more than 80%, 90% or 95% of the forces are derived from the second support in its anchoring to the building or floor. According to an advantageous embodiment of the person conveyor device, 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 according to the invention 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.

Preferably, 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.

It is advantageous if 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. By avoiding such, even less stable connection between the first and second carrier, the power transmission from the second to the first carrier can be further reduced. Preferably, 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.

Advantageously, 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. It is advantageous if the second carrier has carrier elements which have a greater width and / or thickness than corresponding carrier elements of the first carrier. Thus, the second carrier can be performed much more stable than the first carrier. In particular, 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 . In other words, 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.

Preferably, the second carrier is arranged at a distance from the first carrier in or against a conveying direction of the passenger conveyor.

Advantageously, 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.

Preferably, conveying elements are inserted into the first carrier and connected to a circulating belt. In this way, the conveyor elements can be easily inserted into the already arranged carrier. A previous installation is not necessary.

It is advantageous if 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. Concerning . Further advantages of a method according to the invention may be made at this point to avoid repetition of the above statements on passenger transport device according to the invention.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

It is understood that the features mentioned above and those yet to be explained not only in the combination given, but also in other combinations. nations or alone, without departing from the scope of the present invention.

The invention is illustrated schematically with reference to an embodiment in the drawing and will be described below with reference to the drawing.

Figure 1 shows schematically a passenger conveyor device with drive according to the prior art.

Figure 2 shows schematically a passenger transport device according to the invention in a preferred embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A side view of a passenger conveyor device designed as an escalator 100, as known in the prior art, is shown schematically in FIG. The escalator 100 has a support 110, which serves as a support structure for the entire escalator 100. In the carrier conveying elements 151, which are connected to a circulating belt 150, arranged and mounted executable guide means not shown. By way of example, only two conveying elements 151, in the present case steps, are shown, which are connected to a band 150. In addition, individual, unspecified elements of a guide for a handrail of the escalator 100 are shown.

Furthermore, the escalator 100 has a drive 130 which in the present case consists of a motor 131 (for example an electric motor), a gearbox 133 and a drive shaft 140. The drive 130 is partially surrounded by a frame 145 and is arranged in total in the carrier 110 and fixed there or on this. The belt 150 with the steps 151 runs around the drive shaft 140 and is non-positively and / or positively connected thereto. The belt 150 can thus be moved by rotating the drive shaft 140.

The drive forms as it were a separate assembly around which the carrier 110 is built, so that the drive 130 is fixedly connected to the carrier 110. Here it is crucial that the Carrier 110 is stable, so that forces acting on the drive shaft 140 during operation of the escalator 100, well in and on the carrier 110 can be derived. The carrier 110 is necessarily very wide (in a direction perpendicular to the plane of the drawing) due to the steel beams required for stability.

FIG. 2 shows a side view of a passenger conveyor device according to the invention designed as an escalator 200 in a preferred embodiment. The escalator 200 has a first carrier 210, in which conveyor elements 251, which are connected to a revolving belt 250, are arranged and are mounted so as to be able to guide on non-illustrated guide devices. By way of example, only two conveying elements 251, in the present case steps, are shown, which are connected to a belt 250. In addition, individual, unspecified elements of a guide for a handrail of the escalator 200 are shown.

The first carrier 210 serves only as a support structure for the steps 251, or the belt 250 (as far as it runs within the first carrier 210), the belt 250 leading components and the handrail. The first carrier 210 is therefore constructed, for example, only from perforated plates, possibly with additional supports.

Furthermore, the escalator 200 has a drive 230, which is arranged in a second carrier 220. In the present case, the drive 230 has a motor 231 (for example an electric motor), a service brake 232 attached to the motor 231, a transmission 233 and a drive shaft 240.

The drive 230 is partially surrounded by a frame 245 or is arranged in the frame 245, which serves as a protection and stabilization for one, and on the other table forces can transmit and is arranged in total in the second carrier 220 and secured thereto. The belt 250 with the steps 251 runs around the drive shaft 240 and is non-positively and / or positively connected thereto. The belt 250 can thus be moved by rotating the drive shaft 240.

The escalator 200 has no mechanical connection, such as a carrier element, between the first carrier 210 and the second carrier 220, which is a major part of the forces which, during operation, are conveyed by the steps 251 connected to a revolving belt 250 as conveying elements 230, transmits to the first carrier 210. Single- lent the belt 250 with the steps 251 is guided from the first carrier 210 to the second carrier 220 and back again. For this purpose, although rails or the like. However, these are not used to transfer substantial forces from the second carrier 220 to the first carrier 210.

The second carrier 220 can now be fastened with its underside by means of fastening means in a floor element. For example. can be provided for screws. On the other hand, the first carrier 210 may rest on a bottom element with the upper end (in FIG. 2 only the upper end, which is for example arranged on an upper floor).

In an operation of the escalator 200 act, as well as in the escalator of Figure 1, forces on the drive shaft 240. The majority of these forces on the drive shaft 240 is now derived in an escalator according to the invention via the second support 220 in the ground. The first carrier 210 can therefore - as already mentioned above - be made very light and narrow. For example. the escalator can thus be led through a narrow tunnel. The second carrier 220, however, has a stable construction, for example. With steel support elements, so that the forces can be derived.

It should also be noted that in a passenger transport device according to the invention, a simple connection that does not withstand the forces occurring or that does not support the first carrier, in particular with the drive, may be provided between the first carrier and the second carrier. Such a connection can, for example, serve as an assembly aid or as protection for the belt running between the first and the second carrier with the conveying elements. Such a simple, non-load-bearing connection still allows for a simple and lightweight first carrier that does not have to absorb forces from the drive shaft.

In the embodiment shown is also clearly the very easy accessibility and thus also interchangeability of the second carrier 220 and the drive 230 to see, since no surrounding the drive carrier of the entire passenger transport device, such as in the escalator shown in Figure 1 of Case is, exists.
