Description

[0001] The invention relates to a system with a rail-guided vehicle.

[0002] It is known that rails for public transport, such as railways, trams or the like, are made of steel.

[0003] A system with a rail-guided vehicle is known from FR 1 200 967 A.

[0004] US patent 5 878 785 A describes a machine frame component for the process industry.

[0005] From DE 40 11 013 A1 a temperature-controlled rail construction for tracks with high speeds is known.

[0006] A system with a controllable switch is known from DE 10 2006 026 773 A1.

[0007] The invention is therefore based on the objective of further developing a rail-bound transport system, whereby the most cost-effective production possible should be made possible.

[0008] According to the invention, the problem is solved in the system according to the features specified in claim 1.

[0009] Key features of the system with a rail-guided vehicle are that a rail section, arranged to be movable by at least one actuator, is located in the system, in particular in one or between two track sections. wherein the actuator is controllable and can be driven by a medium, in particular by a medium under overpressure against the environment, such as compressed air, air, water, oil or hydraulic oil, so that force can be generated by the actuator to move the movable rail part, wherein stationary rail sections of the system have a recess for conveying the medium to the actuator, the rail components are manufactured as extruded profiles.

[0010] An advantage of this design is that the stationary rail sections not only serve as support and guide rails for the vehicle, but also function as waveguides for data transmission. Additionally, they also serve to conduct a medium that powers an actuator, which in turn drives a movable rail section. This allows for the operation of a lift or a switch.

[0011] Preferably, the actuator's electronic circuitry is powered via an inductive coupling to the primary conductor laid along the stationary rail sections. For this purpose, the actuator's electronic circuitry has a secondary winding which is inductively coupled to the primary conductor. Thus, the primary conductor supplies power not only to the movable, rail-guided transport vehicle but also to the electronic circuitry of the stationary actuator.

[0012] The actuator can therefore be electrically controlled, but its power supply is provided via the "energy-laden" medium, i.e., the medium that is under pressure relative to the environment.

[0013] In an advantageous embodiment, the actuator can be electrically controlled, particularly by a higher-level control system. A key advantage is the ease of communication, especially via a fieldbus protocol such as the internet, Profibus, or CANbus. Furthermore, an electrically controllable valve can be incorporated into the actuator for control purposes, thus simplifying its manufacture.

[0014] In an advantageous embodiment, control signals are transmitted via the waveguide area or slotted waveguide area from a higher-level control unit to an actuator. A key advantage is that a recess in the continuous cast profile is sufficient for data transmission.

[0015] In a preferred embodiment, the actuator incorporates an electronic circuit. The advantage here is that simple control by a higher-level controller, i.e., an electrical controller, is possible.

[0016] In an advantageous embodiment, the movable rail section is movable between at least two positions, wherein in a first position it can be aligned with a first stationary rail section and in a second position it can be aligned with a second stationary rail section. An advantage of this is that a lift or a switch can be manufactured easily.

[0017] In a process for manufacturing different variants of rails, in particular monorail rails or monorail overhead line rails, from a kit, it is important that the kit includes a rail profile part and two different reactive parts. wherein the rail profile part has an interface to which one of the various reactive parts can optionally be connected.

[0018] A key advantage is the two-part design. This allows for the integration and attachment of a suitably effective reactive component to the rail, depending on the vehicle's electric drive system (e.g., linear eddy current motor, asynchronous motor, synchronous motor, reluctance motor, or similar).

[0019] In further development, the rail profile part has drilling aids, in particular drilling notches, for forming the interface, especially as a drilling aid when making holes, wherein, for the production of a first variant, a first drilling aid is used to connect the reactive part, in particular to produce a hole for a screw connecting the reactive part and the rail profile part. In another variant, a different drilling aid is used to connect the reactive component, particularly for creating a hole for a screw connecting the reactive component and the rail profile. The advantage here is that, depending on the selected rail profile, a correspondingly differently positioned hole can be easily drilled into the rail profile. This allows for the connection of reactive components that can be joined using centrally or off-center connecting screws, thus enabling different operating mechanisms. In particular, a rack can also be used as the reactive component, allowing for the construction of a linear geared motor in which a geared section of the motor, driven by an electric motor, engages with the rack.

[0020] In further development, the reactive component can be a blade of a linear asynchronous motor or an eddy current motor, a permanent magnet-receiving holding element of a synchronous linear motor, a reactive component of a reluctance motor, or a rack. An advantage of this is that different operating principles can be implemented in the linear drive of the vehicle. In particular, converting an existing arrangement from one operating principle to another is very simple and quick.

[0021] In an advantageous embodiment, the rail part is designed as a rail profile part, wherein the rail profile section has several spaced-apart drilling aids. An advantage of this is that, depending on the desired design variant, i.e., depending on the reactive component, holes can be drilled into the rail profile section easily, quickly, and with high precision. In this way, a high variance of rails can be produced with a small number of parts in the kit for the inventive series.

[0022] In an advantageous embodiment, the rail profile section is manufactured as an extruded casting, particularly with the drilling aids, and especially wherein the rail profile section is made of aluminum. An advantage of this is that no additional effort is required to produce the drill notches.

[0023] In an advantageous embodiment, a recess for the passage of a cooling medium, such as air, compressed air, water, oil, or hydraulic oil, is arranged in the rail profile section. The advantage here is that the rail profile section, which may be heated, for example, by eddy currents, can be cooled with the cooling medium. The recesses can be designed in such a way as to improve the stability of the rail profile section. For this purpose, they are, for example, designed with a circular cross-section.

[0024] In an advantageous embodiment, the rail profile section has at least one running surface for a vehicle wheel. The advantage here is that several functionalities can be implemented using the rail, such as running surfaces for the wheel and guide wheel, as well as a reactive element, data transmission via waveguides and slotted waveguides, and / or the passage of a cooling medium through a cooling channel.

[0025] In an advantageous embodiment, the drilling aids are designed as notches extending in the direction of the rail and running parallel to each other, in particular drilling notches.

[0026] In particular, drill notches are arranged on the top surface and further drill notches on a side surface, so that a primary conductor can be guided through a bore made in the drill notch. An advantage of this is that a bore can be easily made at a predetermined rail position, thus allowing a cable to be guided through it from the side surface of the rail profile section facing the vehicle to the side of the rail profile section facing away from the vehicle.

[0027] In an advantageous embodiment, the rail profile part has a recess used as a waveguide and a recess used as a slotted waveguide, wherein - an antenna for coupling electromagnetic radiation into or out of the waveguide, - an antenna for coupling electromagnetic radiation into or out of the slotted waveguide and - The vehicle is equipped with an antenna for coupling electromagnetic radiation into and out of the slotted waveguide. An advantage of this is that data from the vehicle can be transmitted via the slotted waveguide to the nearest power feed point, and from there, data intended for other devices, such as other power feed points or a central computer, can be transmitted further via the waveguide.

[0028] In an advantageous embodiment, the frequency of the electromagnetic waves injected into the waveguide differs by less than a factor of two from the frequency of the electromagnetic waves injected into the slotted waveguide. An advantage of this is that essentially a similar frequency range can be used, and thus the recesses in the slotted waveguide profile are of similar size. In this way, high stability of the rail profile section can be achieved through a suitable arrangement of the recesses.

[0029] In an advantageous embodiment, a bore is provided in a first drilling aid to which a first reactive element is screwed. A second drilling aid, spaced apart from the first, is unused and located on the rail profile section, particularly for use with a screw connection to a reactive element different from the first. The advantage here is that various versions can be produced with few different parts, i.e., from a small kit of components.

[0030] In a preferred embodiment, the drilling aids are arranged in a groove, particularly at its base. It is advantageous that the groove walls can be used for centering and lateral limitation.

[0031] In a preferred embodiment, the groove is incorporated into a running surface. An advantage of this is that the vehicle can be supported on both sides of the groove by means of wheels on the running surface.

[0032] In an advantageous embodiment, further recesses usable as waveguides are arranged in the rail profile section, the dimensions being so small that a frequency at least twice as high as that of the slotted waveguide must be used. An advantage of this is that additional data transmission channels can be provided.

[0033] In an advantageous embodiment, the rail profile section has mounting elements to which a holding element, in particular a plastic profile section, can be attached. A medium-frequency alternating current, particularly with a frequency between 10 and 500 kHz, can be injected into this holding element. This allows a secondary winding located on the vehicle to be inductively coupled to the primary conductor, which is laid out in the direction of the rail. A capacitor is connected in series or parallel to the secondary winding such that its resonant frequency essentially corresponds to the frequency of the alternating current injected into the primary conductor. An advantage of this is that contactless energy transfer to the vehicle is enabled. However, this process generates eddy currents in metallic parts, which lead to heating. Cooling channels are provided in the rail profile section to conduct a cooling medium.

[0034] Further advantages arise from the dependent claims. The invention is not limited to the combination of features of the claims. For those skilled in the art, further meaningful combinations of claims and / or individual claim features and / or features of the description and / or the figures will become apparent, in particular from the problem statement and / or the problem arising from a comparison with the prior art.

[0035] The invention will now be explained in more detail with the help of illustrations: In the Fig. Figure 1 shows a cross-section of an EHB rail according to the invention, wherein the opening of a slotted waveguide 1 is attached laterally. In the Fig. Figure 2 shows another EHB rail according to the invention in cross-section, wherein the opening of a slotted waveguide 1 is located at the bottom. In the Fig. 3 is the one for Fig. 2. A proper oblique view is shown, in which a sword is detachably connected to the rail. In the Fig. 4 is the one for Fig. 2. A proper oblique view is shown, in which a rack is detachably connected to the rail. In the Fig. Figure 5 shows a lift, in which a rail section 50 can be driven by actuators 51. In the Fig. Figure 6 shows a switch, where a track section 50 can be driven by actuators 51.

[0036] In the Fig. Figure 1 shows the profile of the continuously cast EHB rail. The continuously cast profile includes recesses that extend throughout in the direction of continuous casting.

[0037] In the upper part of the EHB rail, two separate recesses 14 are arranged, which can be used as cavities for the transmission of electromagnetic waves. The recesses 14 can therefore optionally be used as waveguides.

[0038] On the outer surfaces, particularly on the top and side walls of the wall surrounding the recesses 14, running surfaces for wheels are provided. A running surface 4 for load wheels is provided on the top surface, which essentially transfers the weight of the rail vehicle into this running surface 4 on the top surface. The force must be transmitted through the rail profile to its suspension, where it is then transferred to the suspension.

[0039] The running surfaces 3 for the guide wheels of the rail vehicle are provided on the side surfaces of the wall. This allows the vehicle to be guided laterally along the rail.

[0040] The wall comprising the recesses 14 is connected via the rail wall 15 to another section of the profile, which in turn has a recess 2 with a closed cross-section, used as a waveguide. Additionally, a laterally open recess 1 is provided, which can be used as a slotted waveguide. Thus, a rail is created in one piece that not only supports the weight of the vehicle and guides its lateral movement but also allows the transmission of waves. A cavity within the profile is used as a waveguide 2, and a cavity open laterally is used as a slotted waveguide 1. The vehicle guides an antenna for transmitting and receiving electromagnetic waves along the slotted area, enabling continuous data exchange while the vehicle is in motion.The waves coupled into the slotted waveguide 1 propagate along the rail, but a portion emerges at the slot and can therefore be used to receive data. Conversely, a portion of the electromagnetic radiation exiting the antenna is coupled into the slotted waveguide 1 and thus transmitted along the rail direction. The coupling device for coupling in and out of the electromagnetic radiation is not shown in the figures.

[0041] Fastening elements 10, in particular suspension elements, are provided on the wall surrounding the recesses 14 and on the section connected via the rail wall 15. Thus, the EHB rail can be fastened to a hall wall or to T-beams of a system by means of the fastening elements 10, and in particular, can be detachably connected. This allows for quick and easy replacement. The entire rail is replaced, i.e., both the mechanically load-bearing part and the part functioning as an electromagnetically transmitting waveguide.

[0042] On a side surface of the rail wall 15, receptacles 7 for DIN rails, in particular DIN rail fastening devices, are also arranged, so that a DIN rail can be attached which enables further functionalities.

[0043] Furthermore, recesses are provided in the rail profile that can be used as channels 8, in particular compressed air or hydraulic channels. This allows compressed air or hydraulic pressure to pass through in the direction of travel, thus enabling heat dissipation from the rail profile. Since strong alternating magnetic fields emanate from the primary conductor, eddy currents are induced in the rail profile, leading to its heating. The metal construction of the rail profile, particularly aluminum, facilitates particularly efficient heat dissipation to the compressed air or hydraulic channels. Therefore, even plastic-coated wheels or plastic wheels can be used as running wheels and / or guide wheels, meaning that a material pairing of the metal rail and plastic is possible at the running surface. This results in exceptionally quiet operation of the vehicle.

[0044] In the lower section, running surfaces 3 for side wheels are provided on the sides and a running surface 5 for additional guide wheels is provided on the underside.

[0045] A mounting surface 6 for marking devices or codes, in particular barcodes or transmitter masks, is provided on the rail wall 15. This allows the code to be read by means of a sensor mounted on the vehicle, and information about the vehicle's current position can be determined from this. This determination is carried out by means of an electronic circuit in the vehicle, which is electrically connected to the sensor and thus processes the information detected by it.

[0046] The drill notches 9 provide a drilling aid, particularly during continuous casting. This allows for easy drilling into the rail wall 15, enabling the screwing of electronic modules. Furthermore, a primary conductor cable can be routed through such a borehole. Preferably, this primary conductor is clipped into a plastic profile, which is positively and / or force-fitted to the DIN rail mounting system 7, in particular by clipping.

[0047] As in Fig. As shown in Figure 2, an adaptation groove 11 for additional components is incorporated into the upper surface in the version shown there. As in Fig. As shown in Figure 3, a blade 30 is provided, which is either configured as a stationary part of a linear asynchronous motor, in which case the vehicle has a stator with a three-phase winding that interacts with the blade as a linear equivalent to a squirrel cage to generate a feed force in the rail direction. Alternatively, the vehicle has a pole wheel drive as an eddy current drive, in which an arrangement of permanent magnets can be set into rotation by an electric motor, so that these permanent magnets rotate past the blade 30 and thereby generate eddy currents in it, thus generating a feed force in the rail direction.

[0048] With the in Fig. With the rack 40 shown in the 3, even large gradients in the system can be overcome by the vehicle having a gear whose teeth can be engaged with the toothing of the rack, so that slippage of drive wheels is avoided, especially on steep gradients, i.e. high downhill forces.

[0049] As from Fig. As can be seen in Figure 3, the rail profile is designed in such a way that an integrated cable channel 12 is created, so that cables can be inserted and thus easily laid in the direction of the rail.

[0050] Furthermore, an adaptation groove 13 is provided on the profile, particularly on the lower section of the profile, for a plug-in cable duct or other components. This allows a holder to be inserted that, for example, accommodates and holds a primary conductor that is at least partially enclosed by the core of a secondary winding located on the vehicle and thus inductively coupled to it.

[0051] Within the system, power feeds are provided for each track section. These feeds induce a medium-frequency alternating current, specifically with a frequency between 10 and 500 kHz, into an elongated conductor running parallel to the track. This conductor is inductively coupled to a secondary winding located on the vehicle. A capacitor is connected in series or parallel to the secondary winding such that its resonant frequency essentially corresponds to the injected AC frequency, thereby achieving high efficiency in the contactless energy transfer from the primary conductor to the vehicle's secondary winding.

[0052] Slotted waveguide 1 and waveguide 2 are used differently. As described above, data is exchanged between the vehicle and the slotted waveguide, so that it can then be transmitted further within the waveguide to an antenna extending into the waveguide.

[0053] Preferably, this antenna is arranged in the area of ​​the primary current feed. In this area, a slot is milled into the rail section, into which a plate is inserted, so that the waveguide 2 is divided into a front and a rear half-space. Accordingly, an antenna is provided in front of and behind the plate for coupling in or out electromagnetic waves. The signals from the antennas are fed to a respective data transmission device, which is also arranged in the feed area.

[0054] The slotted waveguide 1 is used to establish a stable, shielded radio link for the moving, track-guided vehicles. This means that a vehicle is connected to the slotted waveguide via a mobile vehicle coupler, i.e., an antenna guided along the slot of the waveguide. This enables contactless mobile data transmission.

[0055] The closed waveguide 2 is used for stationary backbone communication. In this case, both the transmitter and receiver are fixed in one location and cannot be moved. The waveguide is closed between the transmit and receive positions, preventing any signal coupling or extraction between them. This achieves stationary data transmission similar to a coaxial cable connection.

[0056] It is important that each track section is assigned an electrical arrangement, which can be described as a power supply, that is not only intended for supplying power to the primary conductor for contactless power supply to the vehicle, but also for coupling signals in and out for data transmission. The signals are coupled into the waveguide 2 and / or into the recesses 14, which can be used as waveguides. In this way, data transmission to all power supplies or a central control unit is enabled, since all power supplies and, if applicable, the central control unit have corresponding antennas projecting into the waveguide 2 or the recesses 14 for data exchange.

[0057] Data can be exchanged between the vehicle and the power supply point in the section of track assigned to the power supply point, which is connected to an antenna projecting into the slotted waveguide 1, by means of the slotted waveguide.

[0058] Although the signals are coupled into the slotted waveguide 1 and the waveguide 2 or the recesses 14 with frequencies from the frequency range between 4 and 8 GHz, the attenuation in the direction of the rail is greater for the slotted waveguide 1 and therefore a lower data transmission rate and / or range is achievable.

[0059] In the waveguide 2 and / or the recesses 14 the attenuation is lower and therefore data transmission at a high rate is possible.

[0060] The feed also includes a converter that forwards or extracts data that is not to be exchanged between the vehicle and the feed associated with the slotted waveguide of the track section to waveguide 2.

[0061] As in Fig. As shown in Figure 2, the adaptation groove 11 has a drill notch arranged centrally in the groove and two further drill notches 20, such that at least one drill notch 20 is arranged on each side of the centrally arranged drill notch; in particular, these drill notches are then arranged off-center. A symmetrical spacing from the centrally arranged drill notch 20 is advantageous.

[0062] The drill notches are designed to extend in the direction of the rail, and are therefore primarily created by the continuous casting tool during continuous casting.

[0063] This makes it easy to drill a hole in the area of ​​the drill notch, as the drill bit does not slip sideways when starting. Once drilled, the hole encompasses drill notch 20.

[0064] During manufacturing, a version according to Fig. 3 or after Fig. 4. For this purpose, the appropriately arranged holes are drilled into the profile part at the corresponding drill notches.

[0065] When choosing the design according Fig. 3 Two bores are used in the off-center notches 20, so that the sword 30 is screwed to the profile part on both sides at its widening arranged in the groove base.

[0066] When choosing the design according Fig. 4 A bore is used in the centrally arranged notch 20, so that the rack 40 is screwed centrally to the profile part, in particular wherein the screw connection is arranged in a recess of the rack 40, i.e. at a point with the smallest possible wall thickness.

[0067] Thus, a kit is available that includes the profile section, the rack and pinion, and the guide rail. From this kit, either a variant with a guide rail or, alternatively, with a rack and pinion, can be built. Therefore, a large number of variants can be produced with a small number of parts. In this way, a series of different rail profiles can be created from the kit.

[0068] Preferably, further drill notches are also designed parallel to the rail direction and provided in the adaptation groove, thus enabling further screw connections at different distances from the centrally arranged drill notch.

[0069] In further embodiments according to the invention, not only the sword or rack but also other reactive parts, such as a holding part for permanent magnets to form a synchronous linear motor or a reactive part of a linear reluctance motor, are included.

[0070] In further embodiments according to the invention, a drill notch is used instead of a drill notch arranged centrally.

[0071] As in Fig. As shown in Figure 5, a system with a rail-guided transport system can be implemented, wherein the rail arrangement is composed of rail parts 50, each rail part preferably according to Fig. 1. Two actuators 51 are connected to one of the rail sections 50, so that it can be driven in the vertical direction. The rail section is designed to be long in the direction of travel such that a rail vehicle can be moved vertically together with the rail section 50.

[0072] In particular, the rail vehicle is less extended in the direction of travel than the rail section. The driving force of the actuators 51 is correspondingly high.

[0073] The actuators 51 can be operated with a medium such as compressed air or hydraulic oil. This medium is introduced at a feed station into a channel 8, in particular a compressed air channel or hydraulic channel, and is fed in, in particular, at a correspondingly high pressure. The medium can thus be transported to the lift via the rail sections arranged in series.

[0074] There, for example, the medium is conveyed from the last stationary, i.e., immovably arranged, rail section to one or more actuators 51, which are thereby operated. The actuators include, for example, a controllable valve that supplies the pressurized medium to a cylinder with a reciprocating piston, so that this piston performs a linear movement after the valve opens. In this way, the movable rail section can be driven by the piston, thus forming a lift, and can be transported vertically together with the vehicle connected to the rail section, for example, with the vehicle suspended from the rail section. After completing its vertical movement, the vehicle can continue its journey in the vertically higher rail section.

[0075] As in Fig. As shown in Figure 6, a switch can also be implemented in an analogous manner, whereby the movable rail section is displaceable in the horizontal direction, so that the vehicle coming from a first rail section may continue its journey in one of the two optionally traversable rail sections.

[0076] As soon as in the exemplary embodiment after Fig. 5 or Fig. 6. If the movable rail section is positioned in alignment with an adjacent stationary, i.e., immovable, rail section, data transmission is also possible, since the waveguide area of ​​the two aligned rail sections is also aligned and thus the electromagnetic waves can be transmitted between the waveguide area of ​​the stationary rail section and the waveguide area of ​​the rail section movable by the actuators.
