Description

Sliding conductor, current collector and sliding conductor system

Technical Field

The present invention relates to a trolley wire/trolley wire according to the preamble of claim 1, a current collector according to the preamble of claim 12 and a trolley wire system according to the preamble of claim 24.

Background

In known trolley wire systems, a movable electrical load is moved along the trolley wire. For supplying the load, the load is equipped with a current collector, the sliding contacts of which engage in conductor bundles which are guided along a sliding conductor. The load may be, for example, a transport hook of an overhead rail, a cable trolley movable on the rail or a so-called E-RTG container crane, which are equipped with an electrical travel drive, which is supplied with power by a trolley conductor.

In order to be able to transmit data, for example control data, to a load, in the known trolley line system a so-called slotted waveguide/slotted hollow conductor or leaky waveguide is guided parallel to the conductor bundle of the trolley line, into which slotted waveguide or leaky waveguide an antenna arranged on the load engages.

Document DE 102004008571B 4 discloses a support rail profile designed as a support rail of an I-shaped carrier, which has an integrated slotted waveguide for transmitting data in a sliding rail device. The slotted waveguide is provided there with a downwardly directed longitudinal slot in the lower bottom part of the support rail, into which slot the antenna of a vehicle that can be moved along the support rail extends. On the side, i.e. rotated by 90 ° relative to the longitudinal slot, a busbar holder and the busbars held therein are arranged on the support rail.

Document DE 102011119351 a1 discloses a transport system with a rail profile of a vehicle and a rail system guided on a rail, wherein a slotted waveguide is provided on the rail profile and two antennas are provided on the vehicle, which antennas are spaced apart from one another in the direction of the rail and project into the slotted waveguide, wherein the rail profile is designed to be straight. Where the slotted waveguide is also arranged at a distance from the current-carrying conductor bundle on the I-shaped carrier.

Document DE 102011108584B 1 discloses a data transmission device with a slotted waveguide profile which is mounted in a stationary longitudinal direction in a stationary manner. The antenna of the movable moving member extends into the longitudinal slot of the slotted waveguide profile, the movable member being movable with the antenna along the slotted waveguide profile in the slotted waveguide profile.

Document DE 102012002085 a1 discloses a slotted waveguide with laterally extending longitudinal slots for a rail vehicle that can be moved along a rail. In order to prevent dust and water from entering the longitudinal slot of the slotted waveguide, the developed deflector is arranged in a T-shaped cavity, which is usually inclined by 90 °, so that the longitudinal slot is oriented vertically downwards after the deflector. The antenna of the rail vehicle engages vertically from below into the longitudinal slot. The electromagnetic waves are deflected downward from the T-shaped cavity profile to the longitudinal slot by the deflecting means.

Slotted waveguide technology for transmitting data to rail vehicles has been known for a long time and is described, for example, by Messerschmitt-Documents DE 3505469C 2 or DE 2555909C 3, DE 2918178A 1, DE 3323984A 1, DE 3012790C 1 from Blohm GmbH are known and therefore do not require detailed elucidation.

A problem in slotted waveguides which are guided parallel to the current-carrying sliding conductor is that the data transmission in the slotted waveguide is disturbed by the energy transmission at the current-carrying sliding conductor contact. Since the wiping line contact can not always be guided precisely in the current-carrying conductor bundle, short-circuit contact losses sometimes occur here between the wiping line contact and the conductor bundle, so that the current is not interrupted by the small distance between the wiping line contact and the conductor bundle, but rather is transmitted further through the air. This can lead to interference in the data transmission. The slotted waveguide is thus typically spaced a distance from the conductor bundle and the sliding contact point for conducting current and voltage.

This however requires more space for mounting the slotted waveguide, as is known in particular from the documents DE 102004008571B 4 and DE 102011119351 a 1.

Furthermore, there is the disadvantage that, in particular in the case of a trolley conductor with a vertically downward-oriented conductor bundle and therefore a trolley conductor contact to be inserted vertically from below, the movable antenna of the slotted waveguide also engages from below into the generally downward-opening T-shaped slotted waveguide. In order to achieve good data transmission, the slot-shaped opening of the slotted waveguide should be as narrow as possible. This however leads to: the sideways direction transverse to the direction of movement only allows a relatively small deviation of the antenna from the desired neutral path, since otherwise the antenna would contact the slotted waveguide, which must be avoided anyway. To avoid this, in some applications the T-slotted waveguide is inclined by 90 ° and therefore has a horizontal opening slot, as shown in documents DE 102004008571B 4 and DE 102011119351 a 1. This however leads to: moisture and dirt more easily accumulate on the lower opening gap of the slotted waveguide. Furthermore, in some arrangements it is not possible for structural reasons to configure the slotted waveguide to be accessible from the side.

Document DE 102009024518 a1 discloses an automation unit in a transport engineering installation, which includes means for transmitting energy and data between or from a stationary power track and a moving transport unit to the moving transport unit, and means for detecting and determining the position of the moving transport unit with respect to the distance covered. In addition to greater operational and functional safety, automation units should in particular reduce investment and assembly costs. For this purpose, the power track has integrated means for data transmission and position determination, which are assigned to the mobile transport unit with counterparts for energy extraction, signal/data transmission and path detection.

Document DE 102010048586 a1 discloses a device with a vehicle guided on a rail, wherein at least one waveguide/hollow conductor region is formed in one piece on the rail part for data transmission by means of exciting at least one mode of the waveguide region.

Disclosure of Invention

It is therefore an object of the present invention to provide a trolley wire, a current collector and a trolley wire system which overcome the above-mentioned disadvantages and enable a compact and material-saving construction and a good transmission of tolerances.

The invention achieves this object by means of a trolley conductor having the features of claim 1, a current collector having the features of claim 12 and a trolley conductor system having the features of claim 24. Advantageous developments and embodiments of the invention are specified in the dependent claims.

The sliding contact line described above is distinguished according to the invention in that the signal transmission device and the conductor profile are formed as a structural unit. The conductor track can thus be constructed more compactly, so that production and installation can be simplified and material can be saved. The invention is also based on the current collector described above, which is characterized in that the sliding contact and the antenna are formed as a structural unit. A trolley wire system equipped with such a trolley wire and/or such a current collector may make good use of these advantages.

Advantageously, the signal transmission means may comprise an elongate slotted waveguide extending in a longitudinal direction, the slotted waveguide having a longitudinal slot for data transmission to and from the load.

Alternatively, the signal transmission device may also comprise a code track and a code reading mechanism is provided on the collector instead of or in addition to the antenna.

Preferably, the longitudinal slot and the contact opening of the conductor bundle for receiving the sliding contact can point in the same direction, or the sliding contact and the antenna point in the same direction perpendicular to the longitudinal direction. The sliding contact and the antenna can advantageously be arranged on a common feed for moving together from and to the longitudinal slot of the conductor profile or the slotted waveguide.

The conductor profile can advantageously have at least one sliding surface, transversely to the longitudinal direction, next to the longitudinal slot, for a correspondingly shaped and oriented sliding contact surface of the sliding contact, which can be arranged transversely to the longitudinal direction next to the antenna and electrically insulated from the antenna. In an advantageous further development, the conductor profile can have sliding surfaces on both sides of the longitudinal slot transversely to the longitudinal direction, which sliding surfaces serve for correspondingly shaped and oriented sliding contact surfaces of two sliding contacts which are arranged on both sides of the antenna and are insulated from the antenna.

By a suitable design of the sliding surfaces and the corresponding sliding contact surfaces, a self-centering effect can be achieved, so that driving deviations transverse to the longitudinal direction can be reduced. Preferably, with only one sliding contact, the sliding contact surfaces can be designed as wedge-shaped or rounded, while the corresponding sliding surfaces are designed as V-shaped or rounded. More preferably, the sliding contact surfaces can be inclined and/or rounded oppositely to one another in the case of sliding contacts arranged on both sides, while the sliding surfaces can be correspondingly inclined and/or rounded oppositely. This in turn results in a combination of a V-shaped or rounded sliding surface and a wedge-shaped or rounded sliding contact surface, or vice versa.

In a further embodiment, the longitudinal slot or the antenna or a part of the antenna can be completely or partially inclined by an angle α not equal to 90 ° about the longitudinal direction relative to a movement plane in which the collector vehicle or the collector can be moved with its sliding contact in the longitudinal direction, wherein the angle α is greater than or equal to 0 °, preferably greater than 0 ° and less than 90 °. In an advantageous development, the end of the antenna projecting into the longitudinal slot of the slotted waveguide can be bent by the angle α. Furthermore, the longitudinal slot and the contact opening of the conductor bundle for receiving the sliding contact can be inclined relative to one another by the angle α. As a result, the conductor track can be constructed more compactly and, moreover, driving deviations in the displacement plane running in the longitudinal direction can be compensated for better.

In a material-saving and production-technically advantageous embodiment, the slotted waveguide and the conductor profile can be formed integrally from an electrically conductive material.

The conductor bundle can advantageously be a grounding conductor bundle for grounding the sliding contact and/or at least one further conductor bundle, in particular a phase conductor bundle, can be provided in addition to the conductor bundle.

The sliding contact and the antenna can furthermore advantageously extend parallel to one another and/or be arranged side by side or in succession in the longitudinal direction. But also two antennas may advantageously be arranged one after the other in the longitudinal direction.

Preferably, in the trolley line system according to the invention, the movable electrical load can have a plurality of sliding contact points for contacting the corresponding conductor profiles of the trolley line, wherein the at least one conductor profile forms a ground conductor and/or a protective conductor.

Detailed Description

Fig. 1 shows a side plan view of a part of a trolley conductor system 1 according to the invention, which has a substantially double U-shaped rail 2. A current collector 3 of an electrical load, not shown, is movable on the rail 2 in the longitudinal direction L with running wheels 4. The current collector 3 is used to power an electrical load, such as a container crane, which is movable along the track 2.

On the underside of the rail 2, the trolley wires 6 according to the invention are suspended downward by means of trolley wire retaining structures 5 which are mounted at a distance from one another in the longitudinal direction L of the rail 2. The trolley conductor 6 here has, as can be seen from fig. 2 to 5, three conductor bundle holding structures 7, 7 'and 7 ″ arranged next to one another for holding the elongate phase conductor bundles 8, 8' and 8 ″. Since the phase conductor strands 8' and 8 ″ are of identical construction to the phase conductor strand 8, the embodiment with regard to the phase conductor strand 8 applies accordingly.

The phase conductor bundle 8 has an elongated insulation profile 9 which is held by the conductor bundle holding structure 7. In turn, an elongated, electrically conductive phase conductor profile 10 is inserted into the insulating profile 9, which has an elongated sliding surface 11, which is also electrically conductive and is preferably made of aluminum or steel.

Sliding contact 12 slides on sliding surface 11, and is arranged on sliding contact carrier 13 of collector 3. The sliding contact bearing 13 with the sliding contacts 12 can be moved in a manner known per se by a feed mechanism 14 known per se, which is shown by way of example in fig. 1, onto the sliding surface 11 and away therefrom. During operation, the sliding contact 12 is pressed against the sliding surface 11 at all times, for example by spring force. The additional sliding contacts 12' or 12 ″ shown in fig. 2 with the associated sliding contact mount are of substantially the same design as the sliding contacts 12 and the sliding contact mounts 13, so that the embodiments thereof are suitable accordingly. In particular, each sliding contact 12, 12' or 12 ″ has its own feed mechanism 14.

The phase conductor bundle 8 is used to supply a movable load and is under voltage during normal operation, so that current flows through the sliding surface 11 to the sliding contact 12. The above-described embodiments are known in principle to the person skilled in the art and need not be discussed further.

In addition, a ground conductor bundle 15 is usually provided in such a trolley line system 1 for connecting a movable electrical load to a ground potential of the trolley line system 1. The ground conductor bundle 15 is described below mainly in terms of the detail of fig. 2 a.

For this purpose, the ground conductor bundle 15 has an electrically conductive ground conductor profile 16, which is surrounded by a substantially U-shaped ground insulation profile 17 having a contact opening 18 which is open downward in fig. 2 a. The ground conductor bundle 15 is fixed to the trolley conductor 6 by a conductor bundle holding structure 7 '″ like the phase conductor bundles 8, 8'.

The ground conductor profile 16 simultaneously forms a substantially T-shaped slotted waveguide 19 with a longitudinal slot 20 opening downwards. The longitudinal slot 20 is here directed in the same direction as the downwardly open contact opening 18.

An antenna oriented in the longitudinal direction L also extends through the longitudinal slot 20, which antenna engages into the cavity of the slotted waveguide 19. As can be easily seen in fig. 1 to 2a, the antenna 21 is flanked on both sides by a right ground contact 22 and a left ground contact 23, wherein the antenna 21 is electrically insulated from the ground contacts 22, 23. The antenna 21 and the ground wiper contacts 22, 23 can be raised by the feed mechanism 14 and thereby brought into contact with and held in contact with the ground conductor profile 16, as described above.

The ground sliders 22, 23 are constructed symmetrically and extend parallel to the antenna 21. The ground contact points 22, 23 shown in fig. 2 have at their upper ends ground contact surfaces 24, 25 inclined obliquely outward and downward, which are pressed by means of the feed device 14 against correspondingly inclined sliding surfaces 26, 27 of the ground conductor profile 16. Thereby automatically achieving centering of the antenna 21 in the longitudinal slot 20 of the slotted waveguide 19. If the antenna 21 is slightly tilted, for example, about the longitudinal direction L, the tilted ground contact surfaces 24, 25 lose full-face contact with the sliding surfaces 26, 27. Due to the inclined surfaces 24 to 27 and the contact pressure, the contact surfaces 24, 25 and the sliding surfaces 26, 27 are moved toward one another again, however, until they again bear against one another over their entire surface. In the detail shown in fig. 2a, the ground contact surfaces 24, 25 and the sliding surfaces 26, 27 are not only inclined in a modification of the embodiment shown in fig. 1, but are also slightly rounded in order to further simplify the return to the centered position when the antenna 21 is tilted about the longitudinal direction L.

Since no electrical power is transmitted via the ground wiper 22, 23 during normal operation, there is no risk of an arc being generated between the ground conductor profile 16 and the ground wiper 22, 23, which would adversely affect the data transmission by means of the slotted waveguide 19 and the antenna 21. If there is still a large current flow, an emergency situation is involved in which the trolley line system 1 should be stopped quickly.

The ground conductor profile 16 and the slotted waveguide 19 are produced in one piece from the same material in this example and thus form a structural unit, whereby the production and installation can be simplified. The ground conductor profile 16 and the slotted waveguide 21 may however also be manufactured from separate components and/or different materials. The slotted waveguide 19 may also have other suitable cross-sections.

By integrating the slotted waveguide 19 into the ground conductor bundle 15 or the ground conductor profile 16, the conductor track 6 can be constructed very compactly, so that no space-consuming suspension of the ground conductor bundle and the slotted waveguide apart from one another has to be provided. The conductor track 6 can therefore be constructed to be smaller, requires a smaller amount of material, and also simplifies assembly.

The embodiment of the invention shown in fig. 2 and 2a not only enables a compact design, but also ensures that the antenna 21 is guided as well as possible in the slotted waveguide 19 and the longitudinal slot 20 and thus ensures good and reliable data transmission. Furthermore, the antenna 21 and the ground wiper 22, 23 can simply be moved into the longitudinal slot 20 and the slotted waveguide 19 or onto the ground conductor profile 16 and out of it.

In order to further increase the reliability of the trolley conductor system 1, a further antenna with a lateral grounding trolley 22 'can be arranged on the further feed mechanism 14', as in the embodiment shown in fig. 1. Interruptions, for example, due to thermally separated connection points of the ground conductor profile 16 and the slotted waveguide 19, which are not formed of a continuous material, can thereby be eliminated without interrupting the data transmission.

Furthermore, a known, elongated coding strip 28, which is shown in fig. 1 and can be read by a known, read unit 29 mounted on the collector 3 and thus determine the position, is arranged on the side of the ground-insulating profile 17.

Fig. 3 shows an alternative embodiment of the ground conductor bundle 30. The same or corresponding parts are therefore provided with the same reference numerals and designations, which apply correspondingly to the embodiments described above. The ground conductor insulation profiles are not shown for reasons of clarity.

In an alternative grounding conductor profile 31, a contact opening 32 is provided, through which a grounding contact 33 of the current collector 3 engages. The ground contact point 33 slides on the ground conductor profile 31 along a sliding surface 34 thereof. The ground conductor bundle 30 and the ground sliding contact 33 can be constructed like the phase conductor bundles 8, 8', 8 ″ and the sliding contact 12 provided for energy transmission.

Integrated into the ground conductor profile 31 is an elongated T-shaped slotted waveguide 35, known per se, which extends in the longitudinal direction L and has a longitudinal slot 36 directed downwards. An antenna 37 arranged on the movable load or collector 3 engages in the longitudinal slot 36 in order to enable a data transmission known per se.

The ground conductor profile 31 and the slotted waveguide 35, which are produced in one piece from the same material in this example, thus form a structural unit again, as a result of which the production and installation can be simplified. The ground conductor profiles and the slotted waveguides can likewise be manufactured from separate components and/or from different materials. But the slotted waveguide 35 may also have other suitable cross-sections as known in the art.

By integrating the slotted waveguide 35 into the ground conductor bundle 30 or the ground conductor profile 31, the trolley conductor 6 can again be constructed very compactly, so that no separate, space-consuming suspension has to be provided. The conductor track 6 can therefore be of smaller design and requires a smaller amount of material.

The alternative embodiment shown in fig. 4 differs from the embodiment shown in fig. 3 essentially in the alternative design of the ground conductor bundle 38. The same or corresponding parts are therefore provided with the same reference numerals and designations, which apply correspondingly to the embodiments described above.

The ground conductor profiles 39 of the ground conductor bundle 38 have here been formed as a slotted waveguide 39 of substantially T-shape with a longitudinal slot 41 opening downwards. On top of the cavity of the slotted waveguide 40, a sliding surface 42 for a grounding sliding contact 43 is provided here. Furthermore, an antenna 44 is provided there, which is offset in the longitudinal direction L from the ground contact 43 and is schematically indicated in fig. 4. The antenna 44 can in turn be raised and lowered jointly with the ground contact 43 by means of the feed mechanism 14 as in the previous embodiment.

Fig. 5 shows a further alternative embodiment of the ground conductor bundle 45. The same or corresponding parts are therefore provided with the same reference numerals and designations, which apply correspondingly to the embodiments described above.

In the embodiment shown in fig. 5, which also saves installation space and is therefore more compact, the ground conductor profile 46 has a substantially T-shaped slotted waveguide 47 which is inclined by an angle α different from 90 ° about the longitudinal direction L relative to the displacement plane E in which the current collector 3 is displaced. In particular, the longitudinal slot 48 of the slotted waveguide 47 is also inclined by the angle α and thus projects obliquely at the angle α to the lower right and outwards in fig. 5.

A curved antenna 49 is preferably used, the front antenna end 50 of which, which is important for data transmission, is curved in accordance with the angle of inclination α of the slotted waveguide 47. The antenna end 50 is thereby engaged in the desired manner through the inclined longitudinal slot 48 into the cavity of the slotted waveguide 47, so that no disadvantages with regard to data transmission arise. Because the antenna end 50 in turn extends on the line of symmetry of the T-shaped slotted waveguide 47 due to the curved antenna 49.

The upper slot wall 51 of the longitudinal slot 48 in fig. 5 forms a shield for the longitudinal slot 48 and the opposite, shorter lower slot wall 52 against contamination by rain, dust and other external influences. In the embodiment shown in fig. 5, the upper slot wall 51 can be extended downward by a wall 53 which is bent downward, in order to additionally provide protection for the slotted waveguide 47 and the antenna 49. But this wall portion 53 is not absolutely necessary for achieving the success according to the invention of the inclined slotted waveguide 47. Instead of the curved wall 53, the upper slot wall 51 can also be extended linearly, so that it projects beyond the lower slot wall 52. The curved slot wall 53 can also be omitted completely, so that the two slot walls 51, 52 are of the same length.

A widened section 54 of the ground insulation profile 46, which is slightly resilient with respect to the slotted waveguide 47, is provided on the lower slot wall 52. A sliding surface 55 for the ground contact 56 is again provided on the section 54. The earthing slide 56 can be moved, like the slide 12, 12' or 12 ", by its own feed mechanism 14 toward the sliding surface 55 and away from the sliding surface 55.

The embodiment according to fig. 5 has the additional advantage that: an otherwise small tolerance increase for movement of the antenna 49 in the X-direction extending transversely to the longitudinal direction L. Here, the X direction is also parallel to the movement plane E (in which the collector 3 moves). The sliding contacts 12, 12', 12 ″ and the ground sliding contact 56 are here generally advanced in the height direction Z perpendicular to the displacement plane E. In the embodiment shown here, the displacement plane E extends horizontally in the drawing, i.e. is defined by the longitudinal direction L and the X direction. In contrast, in the case of the conductor tracks with laterally oriented conductor bundles, which are shown in the documents DE 102004008571B 4 and DE 102011119351 a1, the displacement plane extends vertically, since the sliding contact point there is moved from the side to the conductor bundle.

Since the longitudinal slot 48 is inclined by the angle α with its narrow width S, the clearance for the movement of the antenna 49 in the movement plane E, in particular according to the invention in the X direction, increases. Contact of the antenna 49 with the walls 51, 52 of the longitudinal slot 48 can thereby also be better avoided.

Furthermore, instead of the different slotted waveguides described above, further data and/or signal transmission means can also be provided on the ground conductor bundle, since then the advantages of a compact, material-saving and easily assemblable structural unit are also obtained.
