Definitions
- the invention relates to a connection arrangement between longitudinal connection elements of a contact line system and a contact line system with at least one such connection arrangement.
- the wires and ropes used in a contact line system are usually tensioned in so-called post-tensioning lengths.
- the incoming and outgoing contact wires and support cables are guided in parallel over a certain length (e.g. a longitudinal span, usually approx. 30 - 80 m).
- a certain length e.g. a longitudinal span, usually approx. 30 - 80 m.
- Such areas are therefore also referred to as parallel fields.
- successive trailer lengths i.e. an ending and a new beginning trailer length, overlap over a certain area.
- the corresponding ending contact wire, suspended from the support cable is therefore usually positioned above the rails or rails, starting from its target height.
- the road is first pulled upwards and then further outside the rail/track or road area, where it is tensioned on the tensioning device.
- the supporting cable which is connected via hangers or Hanger ropes carrying the contact wire also follow this course.
- the new contact wire is attached to the rail/track area in the same way, but coming from the corresponding tensioning device from the other direction. brought to the carriageway/road and introduced from above until it has reached the target contact wire height.
- the contact wires and supporting cables are brought in and out of a chain structure, one of the chain structures must necessarily cross the other. In the case of two-pole chain systems, the continuous chain systems on both poles cross each other.
- E-highway contact line systems i.e. contact line systems for non-rail-bound vehicles, such as. B. Trucks, compared to contact line systems for rail-bound vehicles, such as. B. railway rolling stock, additional features or Requirements, namely, firstly, two chain structures, since the plus and minus poles are routed via the overhead line and secondly, the hangers or Hanger ropes maintain a specified distance between the support rope and the contact wire, which must not be exceeded. Due to this constellation, it is almost unavoidable that corresponding ropes and/or wires touch and thus grind them against each other. Particularly in the parallel fields, the contact wire and/or supporting cable of the crossing chainwork can be attached to the hangers or Grind the hanger ropes of the other chain.
- the invention is based on the object of specifying a connection arrangement with which the direct grinding of crossing conductors against one another is avoided.

- the solution according to the invention has the advantage that because the connecting rope and thus one of the crossing ropes has a covering, the crossing rope rolls off the covering without a covering and thus the direct rubbing against each other or. Grinding of the two crossing ropes and thus damaging each other until they rise or fall. Rubbing prevented or is at least severely delayed. This means that the wear on the corresponding, crossing cables and wires of the contact line system is significantly lower, which means that maintenance costs can be significantly reduced.

This means that the covering can be easily pulled onto the connecting rope separately as a whole. The required length of the covering can also be easily dimensioned.
- a sleeve or sleeve has a substantially circular cross section. of a pipe is very advantageous because no corners and/or edges can get caught on other elements. Nevertheless, the casing is not limited to a circular cross section or the shape of a tube or a sleeve. Depending on your wishes and requirements, all possible other shapes and/or cross sections and/or sizes are conceivable and possible.
- the covering is made of a low-abrasion material.
- a low-abrasion material In principle, the use of different, different materials is possible, provided they are sufficiently resistant. This is particularly advantageous as it also increases the service life of the casing itself and thus contributes to even lower maintenance costs.
- the covering is secured by means of at least one fastening element.
- Element can be fixed to the connecting rope.
- the distance between the casing and the at least two longitudinal connecting elements is particularly preferably adjustable by means of the at least one fastening element.
- the position of the casing between the longitudinal elements not only exactly according to the local conditions or. Requirements are set, but the position is also very simple and uncomplicated to adapt to boundary conditions that change over time, for example changes in length due to temperature changes, sagging of the longitudinal elements over time, etc. , can be customized.
- the covering should advantageously be as large or be dimensioned long so that changes in the position of the unrolling rope, for example.
- B. also covered in the event of temperature changes. are included.
- the at least one fastening element is fixed to the connecting rope and the covering rests on the fastening element.
- the lower limit of the area in which contact between crossing ropes is to be expected can therefore advantageously be set very easily and the covering lies due to gravity without additional measures or Aids are placed loosely on the fastening element without a firm connection.
- the covering is dimensioned in such a way that the covering cannot slip over the fastening element.
- the fastening element is similar to the pipe or sleeve-shaped casing, a substantially circular cross section, the diameter of which is larger than the diameter of the casing. This can prevent elements located underneath, such as the lower rope clamp, etc. , can be damaged by the covering.
- the at least one fastening element is fixed to the connecting rope and alternatively the covering is connected centrally to the fastening element, whereby the weight distribution or -load on the only fastening element in this embodiment is optimized.
- the covering can alternatively be fixed to the connecting cable by means of two fastening elements, the two fastening elements being fixed to the connecting cable and a fastening element in the upper region of the covering and a fastening element in the lower region of the covering with the covering connected is .
- This is a particularly safe embodiment of the invention.
- the invention is not limited in number to one or two fastening elements.
- additional fastening elements can also be used, which can be located in all sensible positions between the longitudinal elements, for example the support cable and contact wire.
- the at least one fastening element is designed as a ball or roller bearing.
- Such bearings are advantageously extremely robust, easy to handle, very low-maintenance and are quickly available in any quantity.
- the connecting rope is particularly preferably a hanger rope, since assembly is particularly easy here.
- a contact line system is particularly preferably equipped with at least one connection arrangement according to one of claims 1 to 12.
- connection arrangement consists of a movably supported casing, for example a sleeve, over one of the two crossing cables and at least one fastening element between this cable and the enveloping sleeve.
- the at least one fastening element is, on the one hand, attached to one of the crossing ropes and fixes the position of the covering and, on the other hand, ensures mobility or
- the casing, for example the sleeve can be rotated safely. This is done e.g. B. form-fitting or supported by sliding or friction elements, ball or rolling bearings, etc.
- the connection arrangement according to the invention thus makes it possible to prevent or prevent damage to crossing cables and/or wires of contact line systems, particularly in parallel fields.
- connection arrangement according to the invention and contact line systems with such connection arrangements can be used and suitable for both rail-bound and non-rail-bound electric vehicles, in particular for eHighway systems for trucks or e-buses.
