The present invention relates to a device for compensating for variations in the length of a conductor rail.

An arrangement according to the preamble part of valid claim 1 is known from EP 3260326 A1. An object of the present invention is to improve the known device.

This task is implemented by the feature of the independent request item. The preferred embodiment is the subject of a dependent claim item.

According to one aspect of the present invention, a device for compensating for changes in the length of a conductor rail extending in the direction of travel of a rail vehicle and comprising a front conductor rail portion as viewed in the direction of travel and a front conductor rail portion as viewed in the direction of travel a rear conductor rail portion behind the front conductor rail portion, the apparatus includes a first carrier portion connectable to the front conductor rail portion and having a guide groove side portion in which a guide groove extending in the longitudinal direction is formed, and a second carrier portion, which can be is connected to the rear conductor rail portion and is arranged in close proximity to the first carrier portion, as seen in a transverse direction at right angles to the direction of travel, and has a guide slot side resting against a guide slot side portion of the first carrier portion, wherein The guide grooves extending in the guide direction are furthermore formed in the guide groove sides of the second carrier and wherein, seen in the direction of travel, the rear locking element adjoins the rear of the guide groove of the first carrier and the front locking element abuts In front of the guide groove of the second carrier part, the locking element engages in the transverse direction in the guide groove of the respective other carrier part.

In contrast to the device mentioned at the outset, the specified device is based on the idea that the two carriers could be separated if pulled sufficiently far from each other. To avoid this, positive locking elements are used, not only for positive locking in the transverse direction, but also for mutual positive locking in the direction of travel. In this way, the relative movement paths of the two carriers towards each other are limited and unintentional detachment from each other is effectively avoided.

In the specified embodiment of the device, the positive locking elements are arranged at opposite ends of the carrier part as seen in the longitudinal direction. In this way, the maximum path for length variation compensation is available before the two bearing parts abut against each other.

In a further embodiment of the specified device, the positive locking element is designed as a sliding guide element that is positively held in the guide groove in the transverse direction. In this way, the positive locking element can be manufactured independently of the rest of the carrier without undercuts requiring complex manufacturing processes.

In a specified embodiment of the device, the rear sliding rail element is received immovably in the guide groove of the first carrier and the front sliding rail element is received immovably in the guide groove of the second carrier in the longitudinal direction middle. This can be achieved in a material locking manner, such as by welding or gluing, in a friction locking manner, such as by wedging, in a press fit, such as by a locking pin, or a combination thereof.

In a preferred embodiment of the specified device, the sliding rail element has a cross-section with a double T-shaped profile. In this way, the two carriers can be constructed uniformly in a symmetrical manner with respect to each other, thus reducing manufacturing costs.

In yet another embodiment of the specified device, a press-fit area for the press-fit of the positive locking element with the respective other carrier is present on each carrier of the guide groove, each press-fit area Has interruptions as viewed in the longitudinal direction. In this way, openings are created through which impurities accumulated in the guide grooves can be removed.

In a further embodiment of the specified device, the guide grooves are recessed in the region of the interruptions in the region of the interruptions in each carrier portion, in a height direction transverse to the transverse direction and transverse to the direction of travel. In this way, remaining residues of accumulated impurities can collect under the slideway of the positive locking element and thus do not interfere with the sliding guide.

In a particularly preferred embodiment of the specified device, the interruption in each carrier is shorter than the positive locking element engaged in the corresponding guide groove, in order to prevent the positive locking element from being pulled from the respective other carrier. Unintentional release.

In a further embodiment of the specified device, the positive locking elements are mounted such that they can slide in the guide grooves. In this way, the device can be provided in a low-maintenance, robust and cost-effective manner.

In yet another embodiment of the specified device, each carrier comprises two guide grooves and two positive locking elements arranged one above the other in a height direction transverse to the direction of travel and transverse to the transverse direction.

According to a further aspect of the present invention, a device for compensating for variations in the length of a conductor rail extending in the direction of travel of a rail vehicle and comprising a front conductor rail portion as viewed in the direction of travel and a portion of the conductor rail as viewed in the direction of travel On the rear conductor rail portion behind the front conductor rail portion, the device includes a first carrier portion connectable to the front conductor rail portion and having a guide groove side portion in which a guide groove extending in the longitudinal direction is formed, and a second carrier portion, which can be connected to the rear conductor rail portion and arranged adjacent to the first carrier portion, as seen in a transverse direction at right angles to the direction of travel, and having positive locking elements that are in the transverse direction of the first carrier portion engaging in the guide groove, a first conductive rod is placed on the first carrier portion against a height direction at right angles to the direction of travel and at right angles to the transverse direction and the first conductive rod is conductively connected to the first carrier portion, A second conductive bar, placed on the second carrier in a direction opposite to the vertical direction and connected to the second carrier in an electrically conductive manner, wherein at least one sliding sleeve slides in the direction of travel and is electrically conductive The way is placed on the first conductive rod and is conductively connected to the second conductive rod. According to the invention, the sliding sleeve is loosely mounted on the first carrier part via the mechanical contact element in the direction opposite to the height direction.

Compared to the device mentioned at the outset, in which a gap extending in the height direction is distinctly formed between the carrier and the sliding sleeve moving relative to the carrier, the specified device closes this gap and thus prevents sparks, sparks. The device may be damaged and its functionality impaired in the long term.

In the specific embodiment of the device specified, the mechanical contact element contains an electrically insulating material and thus prevents ambiguous current flow, which could lead to thermal deformation and possibly also impairment of functionality.

In a preferred embodiment of the specified device, the mechanical contact element is inserted into the sliding sleeve in the direction of travel in a positive locking manner acting in the vertical direction, and can therefore be replaced particularly easily for maintenance purposes.

In another embodiment of the specified device, the mechanical contact element is convex towards the sliding sleeve and thus ensures a low mechanical contact resistance and access to the function of the device at the gap of the device mentioned at the outset.

Referring to Figure 1, there is shown an illustration of a rail segment 1 for a rail vehicle, the rail vehicle not being seen further. A rail segment 1 comprises a rail 2 extending in and against the direction of travel 3 (also called longitudinal direction) of the rail vehicle and, as seen in a transverse direction 4 at right angles to the direction of travel 3, including parallel to Two rails 5 extending from each other.

As seen at right angles to the direction of travel 3 and at right angles to the transverse direction 4, the conductor rail 7 extends above the rail 2 in the vertical direction 6, the conductor rail 7, as seen against the direction of travel 3, comprises the arrangement A first conductor rail portion 8, a second conductor rail portion 9 and a third conductor rail portion 10 in a row.

The rail vehicle thus travels guided by the rails 2 in or against the direction of travel 3 and takes the electrical energy required for the drive from the conductor rails 7 via the pantograph. For this purpose, the first conductor rail part 8 and the third conductor rail part 10 are connected to a power supply 11 .

The respective conductor rail parts 8 , 9 , 10 of the conductor rail 7 are subjected to changes in length due to temperature fluctuations, which are designated with reference numeral 12 in FIG. 1 . To compensate for these length variations 12, the conductor rail 7 includes means 13, which will be discussed in detail below. At the location of the means 13 for compensating for the length variation 12, the conductor rail parts 8, 9 are functionally electrically separated from each other to enable compensation of the length variation 12 with little mechanical stress. In principle, however, the two conductor rail sections 8, 9 are able to transfer current between each other at this point.

This is not the case for segment isolators 14 , which, as seen in FIG. 1 in direction of travel 3 , are arranged in front of means 13 for compensating for changes 12 in length. It is provided, for example, to disconnect power for maintenance and repair work in the area of the conductor rails 7 and to ensure the safety of persons in this area. At this point, the conductor rail parts 9, 10 involved must therefore not carry any current between them.

If a separate power supply 11 for the second conductor rail part 9 is to be avoided, the power transfer must therefore take place at the point of the means 13 for compensating for changes in length, which will also be dealt with in detail at a later point.

However, before, the structure of the conductor rail 7 will be explained in detail with reference to the first conductor rail portion 8 based on FIG. 2 . The conductor rail 7 is suspended from a support 15, which is here as an example designed as a tunnel roof. The suspension on the support 15 is implemented here as an embodiment via a support plate 16 , which is held on the support 15 by means of heavy anchors 17 . As seen in the height direction 6, a long rod insulator 18 is attached below the support plate 16, a further support plate 19 is attached at the end opposite the support 15, on which the conductor rail part 8 to be described is in turn held . The attachment of conductor rails to supports is well known and can be seen in detail in eg WO 2019/097325 A1. For the sake of brevity, a more detailed description will therefore be omitted.

The conductor rail section 8 discussed in FIG. 2 is constructed similarly to the other conductor rail sections 9 , 10 and is symmetrical about a symmetry plane 20 extending in the height direction 6 . As seen in the height direction 6 , the upper side of the conductor rail part 8 has a transverse arm 21 which is connected to an extension arm 22 extending in the opposite direction to the height direction 6 . Fishplates 23 may be attached to the spreading arms 22 on their sides facing each other to precisely align the respective conductor rail sections with each other in the height direction 6 .

This alignment can be supported by a positive closing fit acting in the height direction 6 , for example by means of springs 24 and grooves 25 . For permanent fastening, the fishplate 23 is screwed to the extension arm 22 by means of screws 26 . Alignment support by means of springs 24 and grooves 25 is described in DE 202004009420 U1 and can be viewed in detail therein.

On the opposite side of the extension arms 22 from the transverse arms 21 , each extension arm 22 has a rail 27 on which a component vehicle (not further shown) can move, which pulls the extension arms 22 apart for insertion into the carrier Contact line 28 for the electrical energy of the rail vehicle. In the assembled state, the contact line 28 is then positively and non-positively held by two gripping arms 29 extending from the extension arms 22 towards each other towards the contact line 28 .

The conductor rail part 8 shown in FIG. 2 is followed by means 13 for compensating for the variation 12 of the length of the conductor rail 7 indicated schematically in FIG. 1 . This is explained in detail below with reference to FIGS. 3 to 6 .

The device 13 has a first carrier 30 and a second carrier 31 of the same design as the first carrier 30 , both of which are shown in FIGS. 6 to 8 . In FIG. 3 , the second carrier part 31 is shown separately and explained in more detail below as an example for both the two carrier parts 30 , 31 .

The second carrier 31 has a carrier base body 32 bounded by a front end face 33 and an opposite rear end face 34 , as seen in the direction of travel 3 . In height direction 6 , the carrier base body 32 is bounded by a lid side 35 and a base side 36 opposite the lid side 35 . In transverse direction 4 , the carrier base body 32 is bounded by a contact side 37 and an outer side 38 opposite the contact side 37 .

Two guide grooves 39 are formed in the contact side 37 of the carrier base body 32 , the guide grooves 39 extending in the direction of travel 3 . Each guide groove 39 is open towards the rear end face 34 and closed towards the front end face 33 , wherein the positive locking element 40 protrudes from the contact side 37 in the transverse direction 4 in this closed region. In principle, the positive locking element 40 can be formed integrally with the carrier base body 32 . In the present embodiment, however, the positive locking element 40 is designed as a separate slide which can be inserted into the guide groove 39 of one carrier part 31 and into the guide groove 39 of the other carrier part 30 . This will be described in more detail below. The positive locking element 40 is therefore referred to below as the slide 40 .

Each guide groove 39 is in the shape of a T-shaped groove. This means that the two guide walls 41 form at the opening of each guide groove 39 the two guide walls 41 are guided towards each other in the height direction 6 and are able to press-fit the slider 40 in and out of the guide groove 39 . Guided in the lateral direction 4. The lower guide wall 41 of each guide groove 39 , as seen in the height direction 6 , has a cleaning interruption 42 . If the slider 40 is pushed through the guide slot 39 and pushes foreign objects in front of it, these foreign objects can leave the guide slot 39 through the cleaning interruption 42 . In order to further improve this cleaning effect, the guide grooves 39 can have cleaning recesses 43 in the area of the cleaning interruptions 42 in the opposite direction to the height direction 6 , which for the sake of clarity in all cleaning in FIG. 4 The interruption portion 42 is not indicated with a reference numeral. The cleaning interruption 42 ensures that impurities do not shorten the sliding path of the slide 40 in the guide groove 39 in the assembled device 13 . In addition to the cleaning interruption 42 , the guide wall 41 may also have a fastening interruption 44 through which a fastening tool such as a screw can be easily inserted into the guide groove 39 .

On the lid sides 35 of the carrier base body 32, each carrier 31 having two mounting surfaces 45, on which sliding sleeves 46 can be supported and fixed, the sliding sleeves 46 are described below in Figures 5a to 5c explained in.

In the region of the rear end face 34, the carrier base body 32 is designed as a connection piece 47 that can be inserted between the extension arms 22, such as the fishplate 23 shown in FIG. 2, in order to fasten the device 13 to the conductor rails One of sections 8, 9, 10.

On the base side 36 , the carrier base body 32 has a mounting wall 48 . Holders 49 can be screwed onto the mounting wall 48 and the contact wires 28 can be clamped between the holders 49 . The gripper 49 has the same function as the gripper arm 22 in FIG. 2 . For the sake of clarity, not all of these grippers 49 have been given reference numerals in FIG. 3 .

In the following, FIG. 4 explains the slider 40 having a slider base body 50 extending in the direction of travel 3 . Grooves 51 extending in the direction of travel 3 are moulded into the slider base body 50 at the upper and lower sides as seen in the height direction 6 . Each groove 51 has a groove width 52 selected in such a way that one guide wall 41 of each carrier 30 , 31 can be accommodated in the groove 51 side by side, such that two guide walls 41 Both have as little tolerance release in the groove in the lateral direction as possible.

Between the grooves 51, two mounting holes 53 penetrate the center of the slider base body 50, each of the two mounting holes 53 may optionally be designed with an internal thread, which is not further shown. Fasteners such as screws can be inserted into these mounting holes 53 to fasten the slider 40 in the guide grooves 39 .

The above-mentioned sliding sleeve 46 is described below with reference to Figures 5a to 5d. Their function is to mechanically hold the conductive bar 55 shown in Figure 6 on one of the carriers 30, 31 and to pull electrical energy from the conductive bar 55 of the adjacent carrier 31, 30 so that the electrical energy The transfer of can take place between the two carriers 30 , 31 . From a technical point of view, the sliding sleeves 46 have substantially the same construction and differ only in a few points. The sliding sleeve 46 shown in Figures 5a to 5d is discussed herein as a reference example. Differences from other sliding sleeves 46 in device 13 will be discussed herein.

Each of the sliding sleeves 46 has a sleeve-shaped sleeve body 56 penetrated by a guide hole 57 into which the conductive rod 55 can be inserted. All sliding sleeves 46 have in common that a sleeve-shaped sleeve body 56 is held on a base plate 58 . In the base plate 58 , as viewed from below in the height direction 6 , there are mounting holes 59 into which fasteners such as screws or rivets can be inserted to fasten the sliding sleeve 46 to the one shown in FIG. 4 . Mounting surface 45.

The sleeve-shaped sleeve body 56 receives the above-mentioned conductive rod 55 in a fixed position and functions as a fixed bearing. This can be achieved in various ways, for example by a press fit of the conductive rod 55 in the sleeve body 56 , by material closure of the conductive rod 55 in the sleeve body 56 , or by being guided through the conductive rod 55 and the blocking pin of the pin receiver 60 in the sleeve body 56 .

Some of the sliding sleeves 46, such as the sliding sleeve 46 shown in Figures 5a to 5d, have a further sleeve-shaped sleeve body 56' when viewed in the transverse direction 4, a sleeve-shaped sleeve Both cartridge bodies 56 , 56 ′ are held together on a base plate 58 side by side but spaced apart.

The additional sleeve-shaped sleeve body 56 ′ functions as a floating bearing, which allows the direction of travel 3 as one degree of freedom of movement of the conductive bar 55 , but supports the conductive bar 55 in the height direction 6 and in the lateral direction 4 . In this way, the further sleeve-shaped sleeve body 56 ′ is guided on the conductive bar 55 in the direction of travel 3 . In order to support the freedom of movement of the further sleeve-shaped sleeve body 56 ′ on the conductive bar 55 , bearing elements 61 in the form of sliding or rolling bearing elements can be arranged in the further sleeve-shaped sleeve body 56 ' in the guide holes 57, which can, if necessary, also be supplemented with a sliding agent such as grease. In order to protect the bearing element 61 from external contamination, the guide hole 57 of the further sleeve-shaped sleeve body 56 ′ can be closed at the beginning and at the end by the seal 62 , as seen in the direction of travel 3 . In order to retain the bearing element 61 and the seal 62, corresponding press-fit stop joints 63 can be formed in the guide holes 57 of the further sleeve-shaped sleeve body 56'.

Finally, the electrical contact mediator 64 is arranged in the guide holes 57 of both the two sleeve shaped sleeve bodies 56 , 56 ′, which increases the electrical contact between the sliding sleeve 54 and the conductive bar 55 . The electrical contact mediator 64 can be, for example, a spring which creates a high contact surface between the sliding sleeve 54 and the conductive bar 55 by means of mechanical pressure.

If the sliding sleeve 54 has two sleeve-shaped sleeve bodies 56, 56', the sliding shoe 65 can be held under the other sleeve-shaped sleeve body 56' and the conductive rod 55 is loosely mounted In the sliding shoe 65 , as seen in the height direction 6 . The sliding shoe 65 is shown in FIG. 5 b and has a convex underside 66 as seen in the height direction 6 . As seen above the convex underside 66 in the height direction 6 , the insertion element 67 is held on the sliding shoe 65 , the insertion element 67 can be positively inserted into the insertion groove 68 on the base plate 58 in the direction of travel 3 , so that the sliding shoe 65 is positively held on the base plate 58 in the travel direction 3 . The sliding shoe 65 can in principle be made of any material. However, in the present embodiment, the sliding shoe 65 is made of an electrically insulating material, which ensures a sufficient insulating distance between the further sleeve-shaped sleeve body 56' and the respective adjacent load-bearing parts 30, 31, such that The current is conducted exclusively through the conductive rods. This avoids unintentional voltage flashovers between the further sleeve-shaped sleeve body 56 ′ and the respective adjoining bearing parts 30 , 31 , which could lead to damage to the sliding surfaces and impair the function of the device 13 .

To assemble the device 13 , the sliders 40 are first inserted into the guide slots 39 of the two carrier base bodies 32 , as shown in FIG. 6 , and fixed to the respective carrier base bodies using screws through the mounting holes 53 . Front end face 33 of 32 . The sliders 40 are then inserted into the respective guide grooves 39 at the rear end face 34 of the respective other carrier base body 32 so that both carriers 30 , 31 can be guided towards each other in the direction of travel 3 . In the next step, two conductive rods 55 are used. One end of each conductive rod 55 is fixed in the sliding sleeve 54 using only one sleeve-shaped sleeve body 56 . The further sleeve-shaped sleeve body 56 ′ of the sliding sleeve 54 each having two sleeve-shaped sleeve bodies 56 , 56 ′ is then pushed onto the other end of each conductive bar 55 . The free remaining end of the other conductive rod 55 is then fixed in the sleeve body 56 of the first sleeve shape. In this configuration the base plate 58 of the sliding sleeve 54 is finally fixed to the lid side 35 of the carrier base body 32 of the carriers 30 , 31 , so that the structure of the device 13 according to FIG. 6 is formed.

For mounting the device 13 , for example in the rail segment 1 according to FIG. 1 , the connecting pieces 47 are inserted in the respective conductor rail parts 8 , 9 before or after the device 13 , as seen in the direction of travel 3 , and pass An additional fishplate 69 attached from the outside is screwed on, which can be seen in FIGS. 7 and 8 . However, before screwing, the contact wires 22 are inserted. In the region of the conductor rail sections 8 , 9 , the contact wires can be inserted by means of the already mentioned component vehicles moving on the rail 27 . In the region of the device 13 , the element vehicle can be pulled off the rail 27 in the direction of travel 3 or pushed back again, since the device 13 does not extend beyond the extension arm 22 in the transverse direction 4 . The contact wire 22 can then be attached to the device 13 by means of the above-mentioned clamp 49 . The fishplate 69 attached from the outside ensures that the contact wire 22 is leveled precisely in the height direction 6 , so that the specified device is also suitable for use in high-speed traffic and the pantograph of the rail vehicle does not experience in the conductor rail sections 8 , 9 and any vibrations in the transition between the device 13, even at speeds above 150 km/h.

FIG. 9 shows alternative current conduction for device 13 . In an alternative arrangement, the angle profiles 70 , 71 are held on the carrier base body 32 of the carriers 30 , 31 and are electrically connected to a ribbon cable 73 . The compensation for the change in length 12 described above uses the same means and works in the same way. Only the transmission of electrical energy between the carriers is carried out differently.

The transmission of electrical energy is essentially only necessary when segmented insulators 14 are present and the electrical energy supply on one of the conductor rail sections 8, 9 is not ensured. Otherwise, the transmission of electrical energy using the conductive bar 55 or using the ribbon cable 73 is not required.
