Description

Technical Field

[0001] The utility model relates to a transport device which is provided with a contactless power supply moving device. Background Art

[0002] As is known to all, in rail facilities, mobile devices can move on rails. Utility Model Content

[0003] Therefore, the object of the present invention is to improve the transport equipment as efficiently as possible.

[0004] In the transport equipment, in particular the monorail suspension equipment, the important feature of the utility model is that the transport equipment is provided with a contactless power supply moving device.

[0005] The moving device can move on the track, especially along the track direction.

[0006] The mobile device has a secondary winding which is inductively coupled to a primary conductor laid along the track, and a feeding device serving as a power supply / current source feeds an alternating current into the primary conductor.

[0007] The power supply device comprises a housing part and a heat sink.

[0008] wherein the rail is held by at least one carrier,

[0009] The carrier has a recessed portion, and the cooling body rests on the recessed portion.

[0010] In this case, the housing parts rest on the wings / legs of the carrier.

[0011] The advantage here is that the cooling body rests on the depression, in particular on the bottom of the depression, and heat can therefore flow from the cooling body to the carrier. Since the carrier is metallic and is therefore a good thermal conductor, the heat flow is quickly dispersed by means of the carrier and the heat is thus transported away from the cooling body. In addition, peak temperatures are quickly buffered due to the large thermal capacity. The feed device is thus arranged integrally on the carrier and can dissipate heat effectively due to the direct thermal contact.

[0012] In an advantageous embodiment, the wing at least partially defines or delimits the depression. The advantage here is that the heat sink not only rests on the bottom of the depression but also on the wing, and can therefore also dissipate heat there.

[0013] In an advantageous design, the support member is erected on the bottom of the device. Advantageously, the weight of the track is transferred by the support member, in particular to the bottom of the device.

[0014] In an advantageous embodiment, the heat sink protrudes through the housing part toward the carrier, in particular into the recess. The advantage here is that the heat sink can form direct contact and thus reduce heat transfer resistance.

[0015] In an advantageous embodiment, the carrier has a web / rib, on both sides of which, in particular at both ends of the web viewed in the rail direction, a corresponding pair of wings is formed or formed on the carrier. This has the advantage that the cooling body can be arranged in a cup-shaped depression and thus can effectively transfer heat.

[0016] In an advantageous embodiment, the web and / or the depression extend perpendicularly to the rail direction. An advantage here is that the support acts as a support for the rail.

[0017] In an advantageous embodiment, the wings are parallel to one another. The advantage here is that the support element can be manufactured simply and has a high load-bearing capacity.

[0018] In an advantageous embodiment, the corresponding pairs of wing plates are oriented opposite to one another.

[0019] In particular, they are oriented perpendicularly to the track direction, in particular in the respective horizontal direction, in opposite directions. The advantage here is that a large surface is provided for heat transfer to the ambient air.

[0020] In an advantageous embodiment, the web has a greater extension perpendicular to the rail direction, in particular in the vertical direction, than in the rail direction. This has the advantage that the support element has a high load-bearing capacity.

[0021] In an advantageous embodiment, the carrier and / or the rail is a continuous casting or a drawn part. The advantage here is that simple production can be achieved.

[0022] In an advantageous embodiment, the carrier is made of steel or aluminum.

[0023] The cooling body is made of aluminum, which has the advantage that it provides high thermal conductivity.

[0024] In an advantageous design, the recess is arranged between the first wing of the first pair of wing plates and the first wing of the second pair of wing plates. This has the advantage that the feed device can be positioned precisely and the cooling body rests against the two wing plates, so that the heat loss of the inverter can be efficiently discharged through the cooling body.

[0025] In an advantageous embodiment, the depression is delimited by the web and by the first wing of the first pair of wing plates and the first wing of the second pair of wing plates. This has the advantage that the support element achieves a high load-bearing capacity.

[0026] In an advantageous embodiment, the depression is perpendicular to the rail direction and / or perpendicular to the extension direction / extension direction of the support. This has the advantage that the feed device can be connected to the support from a horizontal direction, in particular can be screwed by means of a screw.

[0027] In an advantageous embodiment, the support element is an I-shaped / double T-shaped support element. The advantage here is that a high load-bearing capacity can be achieved.

[0028] In an advantageous embodiment, the web of the carrier connects two pairs of wing plates, wherein the respective pair of wing plates has—in particular I-shaped—wing plates which are preferably parallel to one another. The advantage here is that a high load-bearing capacity can be achieved.

[0029] Further sensible combinations of features of the description and / or of the drawings will appear to a person skilled in the art, in particular arising from the objectives and / or from a comparison with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Now the utility model is described in detail according to the schematic diagram:

[0031] exist Figure 1 Schematically shows a system for contactless transmission of electrical power according to the invention, wherein a feed device 1 feeds medium-frequency current into a primary conductor, in particular a linear conductor, which is laid elongately along a rail 3 held by a carrier 2 .

[0032] exist Figure 2 The fastening of the power supply device 1 to the carrier 2 is schematically shown in detail in a side view.

[0033] exist Figure 3 FIG. 4 shows a top view of the power feeding device 1 . DETAILED DESCRIPTION

[0034] As shown in the figure, the system has a track 3, along which a movable device 4, in particular a rail vehicle, can move. The movable device has a secondary winding on its lower side, which is inductively coupled to a primary conductor, in particular a linear conductor, laid elongated along the track and thus enables contactless, in particular inductive, transmission of electrical power to the movable device 4.

[0035] The moving device 4 is guided by the rails and can in particular be moved back and forth along the rails 3. Therefore, the drive of the moving device 4 can be powered inductively.

[0036] The rails 3 are preferably arranged horizontally and are held by supports 2 which are spaced apart from one another in the direction of the rails and which are erected and / or fixed on the base of the device having the system.

[0037] The carrier 2 is preferably designed as an I-shaped carrier, wherein a web arranged in the middle of the carrier 2 connects two pairs of wings, wherein each pair of wings has wings at the ends of the web, in particular at the ends of the I-shaped web, which are preferably parallel to each other.

[0038] The wings thus extend on both sides of the web and thus form a depression into which the cooling body 23 of the feed device extends. In particular, the cooling body 23 rests against the web and thus dissipates heat to the carrier 2, which has a high thermal capacity and thus buffers temperature peaks and disperses the heat flow out of the cooling body and discharges it to the ambient air.

[0039] The feed device 1 itself has a housing part, with which it rests on the wing facing the housing part of the carrier 2. This achieves, on the one hand, a mechanically stable support on the carrier and, on the other hand, improved dissipation of lost heat, since the cooling element rests on the metallic carrier 2, in particular on a good thermal conductor.

[0040] The housing parts of the feed device 1 surround a converter in a housing-forming manner, which has a rectifier fed from a public power supply network, whose DC voltage-side connections are connected to DC voltage-side connections of a converter, in particular a single-phase inverter, and whose AC voltage-side connections are fed from the public power supply network.

[0041] The inverter is likewise surrounded by housing parts of the converter in such a way as to form a housing.

[0042] The connections on the AC voltage side of the inverter feed a gyrator, i.e. a four-terminal circuit comprising an inductor and at least one capacitor, wherein these impedances are dimensioned so that the resonant frequency of the gyrator is identical to the frequency of the voltage provided at the connections on the AC voltage side of the inverter. In this way, the gyrator connected and operated in this way is a power source on the output side, which feeds the primary conductor laid as a current loop directly or via a matching transformer. The secondary winding of the mobile device 4 is inductively coupled to the primary conductor laid along the track held by the carrier 2. A capacitor is connected in series or in parallel with the secondary winding, which capacitor is dimensioned so that the resonant frequency of the resonant circuit formed in this way is equal to the frequency of the voltage provided at the connections on the AC voltage side of the inverter. Power can thus be transmitted with high efficiency.

[0043] like Figure 2 As shown, the capacitor 21 extends through the opening of the housing part from the interior space surrounded by the housing part into the environment. Another capacitor can be connected in parallel through the opening in order to fine-tune the resonant frequency.

[0044] The carrier 2 and the rail 3 are preferably made of steel. The cooling body 23 is preferably made of aluminum.

[0045] exist Figure 3 , for better visibility, the distance between the carrier 2 and the feed device 1 with its heat sink 23 can be seen. However, after the feed device has been fixed by means of screws which pass through the housing part and are screwed into threaded holes in the carrier 2, the feed device 1 lies directly on the carrier 2, so that the distance disappears.

[0046] In further exemplary embodiments according to the invention, the support part 2 is made of aluminum and / or the rail 3 is designed as an aluminum continuous casting.
