Technical Field

The invention relates to a cable section for forming a cable of a multi-strand cable for people transportation according to the preamble of claim 1 and to a method for splicing a cable for forming a multi-strand cable for people transportation according to the preamble of claim 12.

Background

Cable sockets are known from the prior art, by means of which a continuous multi-strand cable can be produced from a multi-strand cable, for example as a tow cable or a haul cable for mountain cable cars. Here, the so-called long plug is made at the application site of the continuous cable. In order to meet the criteria herein, a long plug of this type has a length of at least 1200 times the diameter of the multi-strand cable used, so that a sufficient load-bearing capacity of the plug can be established by means of conventional plugging.

This object is achieved according to the invention by the features of claims 1 and 12, while advantageous embodiments and other further developments of the invention can be derived from the dependent claims.

Furthermore, a compact plug-in part, in particular a long plug-in part, can be provided. Furthermore, a short, load-bearing plug-in connection, in particular for long plug-in sections, can still advantageously be provided. For a plug part, in particular a long plug part, a low complexity in terms of production can advantageously be achieved. Furthermore, in the case of a clearly limited available space, in particular in the case of a short length of the region available for plugging, plugging can also be achieved, in particular with a long plugging section. Cost-effective efficiency can advantageously be achieved, in particular while achieving high reliability of the finished plug part, in particular of the long plug part. Furthermore, a low complexity of the production and production of the plug-in part, in particular of the long plug-in part, can be achieved.

In particular, the cable and/or cable section has a nominal diameter d. The diameter d is preferably the nominal diameter of the cable. In particular, the diameter d is the diameter of the smallest circle surrounding the cable and/or cable section, in particular its cross section. The cable is preferably a multi-strand cable, in particular a steel multi-strand cable. The cable particularly preferably has at least one (in particular exactly one) core. Advantageously, the cable is at least partially realized by a plastic material. The longitudinal elements preferably extend in a helical manner around the core, in particular in the manner of a conventional multi-strand cable, and in particular are stranded around said core. In particular, the longitudinal elements have a lay length of at least 4 × d, preferably at least 6 × d, and/or at most 12 × d, and preferably at most 9 × d. The longitudinal elements are advantageously arranged around the core in the following manner: the longitudinal elements are arranged so as not to be in contact with one another at least in sections of the cable and/or cable sections that differ from the plugging position and/or are spaced apart from one another in the longitudinal direction of the longitudinal elements, whereby in particular wear of the longitudinal elements that rub against one another can be avoided or at least reduced. The cable is advantageously configured for a cableway, in particular a passenger cableway. However, the cable may also be configured for a material runway. The cable is in particular a continuous cable, preferably a cableway. The cableway may be, for example, a passenger cableway, in particular for mountain cable cars, and advantageously for city cable cars. Alternatively or additionally, the cableway may be at least partially or completely disposed underground. Material cableways, in particular material transport systems, are likewise conceivable. The cable is advantageously a hauling cable, in particular a rotating and/or continuous hauling rope, and/or a hauling cable, in particular a rotating and/or continuous hauling cable. The cable in the assembled state is advantageously placed around at least one drive element of the drive unit of the runway, in particular around a drive pulley. "configured" means especially specially designed and/or equipped. An "object is configured for a specific function" is to be understood in particular as an object in at least one application state and/or operating state which implements and/or carries out the specific function.

The cable advantageously has a constant diameter. The diameter of the cable may here be chosen to be suitable for the specific application. The diameter is in particular at least 10mm and/or at most 100 mm. For example, if the cable is a traction cable, the diameter is in particular at least 10mm, and advantageously at least 20mm and/or at most 70mm, and advantageously at most 50 mm. For example, if the cable is a haul cable, the diameter is in particular at least 30mm, and advantageously at least 40mm and/or at most 100mm, and advantageously at most 90 mm. Furthermore, the cable preferably has a constant cross section, or at least a cross section that periodically appears along the longitudinal direction of the cable. The cross-section may be circular, in particular in the case of cables, between the longitudinal elements extending over the surface of said cable, with suitable inserts which advantageously fill the intermediate spaces between the longitudinal elements. It is also conceivable that the cross-section corresponds to the cross-section of a conventional multi-strand cable having strands arranged around a core.

In particular, the multi-strand cable for personnel transport is free of a sheath that at least surrounds the cable, in particular a plastic material sheath, a metal sheath, a nylon sheath and/or other sheaths that influence in particular the tensile strength of the cable. In particular, each stranded longitudinal element (in particular except for the insertion end) is free of a sheath surrounding the stranded longitudinal element, in particular a plastic material sheath, a metal sheath, a nylon sheath and/or other sheaths particularly affecting the tensile strength of the cable. An element "free of a sheath at least over a large part" is to be understood in particular as an element which is free of a sheath surrounding at least 51%, preferably at least 75%, advantageously at least 85%, preferably at least 95%, particularly preferably at least 99% of the element. A "sheath" is to be understood to mean, in particular, an element which at least partially surrounds in the circumferential direction a plurality of cables and/or longitudinal elements for transporting people and is preferably made of a material which: this material is different from the material of the multi-strand cables and/or longitudinal elements used for personnel transport, in particular the wire material. In particular, the expression "partially surrounds" is to be understood as surrounding at least 51% of the entire circumference, preferably at least 80% of the entire circumference, or preferably at least 95% of the entire circumference.

In particular, the cable has N longitudinal elements in addition to the core. Preferably, N ═ 6. In particular, the cable is a six-strand multi-strand cable. However, seven or eight strands of cable are equally contemplated. In particular, N is at least 4, advantageously at least 5, and particularly advantageously at least 6 and/or at most 12, advantageously at most 10, and particularly advantageously at most 8. The longitudinal elements advantageously each have an at least substantially uniform cross section. The longitudinal elements are preferably strands which in turn may be composed of a plurality of individual filaments which may in particular be realized at least substantially identical to each other. It is likewise conceivable that the longitudinal elements, for example embodied as strands, comprise different individual filaments and/or other components, such as inserts, fibers, sheathing elements, etc. In particular in the case of the longitudinal elements being embodied as strands, the longitudinal elements advantageously have a lay length corresponding to at least five times, preferably at least seven times, and/or at most fifteen times, and preferably at most eleven times, the diameter of the longitudinal elements. In principle, differently laid longitudinal elements can be used. Furthermore, the laying direction of the multi-strand cables may be the same or opposite to the laying direction of the longitudinal elements or at least of the individual longitudinal elements. An object which is "at least substantially identical" means in particular an object which is constructed in such a way: in this case, the objects can each have a common function, and the largest difference of the objects, apart from production tolerances, is preferably between the individual elements that are independent of the common function, and the objects, apart from production tolerances and/or within the scope of processing possibilities, are advantageously of identical design, in particular, objects that are symmetrical to one another are also to be understood as identical objects. In the present context, an object having an "at least substantially uniform cross section" means in particular that any first cross section of the object along at least one direction and any second cross section of the object along said direction, the smallest area of the difference in area formed when the first and second cross sections overlap is at most 20%, advantageously at most 10%, and particularly advantageously at most 5% of the area of the larger of the two cross sections.

In this context, a "thread" is to be understood in particular as an elongated and/or thin component which can be bent and/or deflected at least mechanically. The wire advantageously has an at least substantially uniform, in particular circular or elliptical, cross section along the longitudinal direction of the wire. The wire is particularly advantageously embodied as a round wire. However, it is also conceivable for the thread to be embodied at least partially or completely as a flat thread, a rectangular thread, a polygonal thread and/or a profiled thread. For example, the wire may be at least partially or completely composed of a metal, in particular a metal alloy, and/or an organic and/or inorganic plastic material, and/or a composite material, and/or an inorganic non-metallic material, and/or a ceramic material. For example, it is conceivable to implement the thread as a polymer thread or as a plastic material thread. The filaments may in particular be embodied as composite filaments, for example metal/organic composite filaments, and/or metal/inorganic composite filaments, and/or metal/polymer composite filaments, and/or metal/metal composite filaments, etc. In particular, it is conceivable that the wire comprises at least two different materials which are arranged relative to one another and/or at least partially mixed with one another, in particular according to a composite geometry. The wire is advantageously embodied as a metal wire, preferably as a steel wire, in particular as a stainless steel wire. If the helix has a plurality of filaments, the filaments are preferably the same filaments. However, it is also conceivable for the spiral to have a plurality of threads which differ from one another, in particular with regard to their material, and/or their diameter, and/or their cross section. The wires and/or the longitudinal elements preferably have in particular a corrosion-resistant coating and/or sheath, for example a zinc coating and/or an aluminium/zinc coating and/or a coating of a plastic material and/or a PET coating and/or a metal oxide coating and/or a ceramic coating or the like.

The plug part is preferably a long plug part and/or is produced in the manner of a long plug part. The socket is preferably a multi-strand cable socket. The number of longitudinal elements of the plug part preferably corresponds to the number of longitudinal elements of the cable. The longitudinal element of the plug part is particularly preferably a longitudinal element of a cable. The plug part is preferably made of the main cable of the cable before connecting said cables to form a continuous cable. The plug part is in particular at the connection location between the ends of the main cables of the cable. The cable advantageously has at least one further cable section without any plug-in connection. The cable section and the further cable section preferably constitute a cable. However, it is likewise conceivable for the cable to have a plurality of cable sections each comprising at least one plug-in section, for example if a part of the cable is replaced, the corresponding replacement section is plugged in by at least two plug-in sections. Advantageously, the plug part has a maximum diameter which deviates from the diameter d of the cable by at most 10%, advantageously by at most 8%, particularly advantageously by at most 6%, and preferably by at most 5%, and in particular is greater than the diameter d.

At least some of the longitudinal elements and advantageously all of the longitudinal elements preferably form at least one insertion end, respectively. At least some and advantageously all of the longitudinal elements particularly preferably form exactly two insertion ends, wherein one insertion end is advantageously formed by one end of a longitudinal element. The insertion end is advantageously inserted into the interior of the cable section instead of the core. The plug-in part particularly advantageously has a plurality of plug-in positions, in particular N plug-in positions, wherein the longitudinal element and preferably the insertion end preferably intersect in such a way that: such that the longitudinal element and the insertion end penetrate the interior of the plug part in opposite directions. The plug-in position comprises in particular at least one plug-in connection, in particular exactly one plug-in connection, preferably a flat connection. The plug section in the region of the plug position N +1 advantageously has a longitudinal element on the surface, preferably wherein two longitudinal elements intersect at the plug position. Alternatively, it is conceivable that two longitudinal elements are placed directly adjacent to each other at the plugging location, such that for example the two longitudinal elements form a parallel knot. The two longitudinal elements, in particular the longitudinal elements which intersect one another at the plugging position, each particularly advantageously form an insertion end, wherein the respective insertion end, in particular starting from the plugging position, is inserted into the interior of the plug part instead of the core in the opposite direction. Preferably, the insertion ends each extend from the center of the plugging location to an end of the insertion end, in particular within the plugging portion. The two insertion ends forming a plug-in position (each starting from the plug-in position) particularly preferably extend in opposite directions of the plug-in part, particularly at least predominantly within the plug-in part, preferably instead of the core.

In particular, the length of the non-inserted sections of the longitudinal elements intersecting each other or alternatively of the longitudinal elements placed next to each other and thus defining and/or forming the section on the surface of the plugging location is at most 15 × d, advantageously at most 10 × d, particularly advantageously at most 5 × d, and preferably at most 2 × d. The length of the plugging connection of the plugging location is therefore in particular at most 15 × d, advantageously at most 10 × d, particularly advantageously at most 5 × d, and preferably at most 2 × d.

The diameter of the plug section in the region of the plug location may be greater than the diameter d of the cable, in particular because the cross section of the plug section at the plug location comprises N +1 longitudinal elements. The at least one plugging position of the plug part particularly defines the maximum diameter of the plug part.

The plug part preferably has 2 × N insertion ends, wherein each end of each longitudinal element is particularly preferably an insertion end. However, it is also conceivable that at least two ends of the longitudinal elements, or of each individual longitudinal element, are connected in a butt joint, and in particular are located on a surface of the plug part, and are, for example, glued and/or welded to each other, and/or are otherwise connected to each other. In this case, the number of insertion ends may be less than 2 × N. For example, only four longitudinal elements may form the insertion end of a cable having six longitudinal elements, while two longitudinal elements are only positioned on the surface of the corresponding plug part for docking. For example, in this case the breaking force of the plug part is mainly determined by the insertion end, while the end of the longitudinal element located in the butt joint may be able to absorb only small forces, for example by welding. The corresponding plug-in part is advantageously simple to produce, in particular because only a small number of longitudinal elements are plugged in.

Preferably, the insertion end is at least partially covered, in particular wrapped, by at least one sheathing material. The jacket material may advantageously be, for example, a plug-in band that can be wrapped around the insertion end. It is also contemplated that the jacket material may be attached to the insertion end in another manner (e.g., coated, fused, extruded, etc.). The sheath material is particularly configured for enlarging a diameter of the insertion end by a sheath of the insertion end. The insertion end is advantageously covered with a sheathing material such that the diameter of said insertion end at least substantially corresponds to the diameter of the core. The diameter of the insertion end, particularly in the unsheathed state, is preferably smaller than the diameter of the core. Within the scope of this text, "at least substantially" is to be understood in particular as: the deviation from the predetermined value corresponds in particular to less than 15%, preferably less than 10% and particularly preferably less than 5% of the predetermined value.

The length of the insertion end is advantageously at most 40 × d, particularly advantageously at most 30 × d, preferably at most 25 × d, and particularly preferably at most 20 × d. The plug part advantageously has at least 2 × N-8, particularly advantageously at least 2 × N-6, preferably at least 2 × N-4, particularly preferably at least 2 × N-2, and preferably 2 × N insertion ends. The plug part has in particular at least two, preferably at least four, particularly advantageously at least six, preferably at least eight, particularly preferably at least ten, and preferably at least twelve and/or 2 × N insertion ends, the length of which is at most 50 × d, advantageously at most 40 × d, particularly advantageously at most 30 × d, preferably at most 25 × d, and particularly preferably at most 20 × d.

The overall length of the plug part corresponds in particular to the spacing between the outermost insertion ends of the plug part, preferably in the longitudinal direction of the outermost insertion ends. At the opposite end side, the plug part is preferably delimited by the core of the cable. The peripheral insertion ends of the plug parts in particular adjoin the core of the cable, wherein the overall length of the plug parts advantageously corresponds to the spacing between the peripheral insertion ends, in particular the ends thereof facing the core. The total length of the plug part is advantageously at most 80 × N × d, particularly advantageously at most 60 × N × d, preferably at most 50 × N × d, and particularly preferably at most 40 × N × d. For example, in particular in the case of a six-stranded cable, the length of the plug part is at most 600 × d, advantageously at most 500 × d, particularly advantageously at most 400 × d, preferably at most 300 × d, and particularly preferably at most 250 × d.

In an advantageous implementation of the invention, it is proposed that the plurality of longitudinal elements each have at least one insertion end with a length of at most 50 × d. Advantageously, the plurality of longitudinal elements each have two insertion ends of length at most 50 x d. In particular, all insertion ends of the plug part accordingly have a length of at most 50 × d. Furthermore, it is conceivable that all longitudinal elements of the plug part each have two insertion ends each having a length of at most 50 × d. However, it is also conceivable that at least one insertion end of the plug part has a length of more than 50 x d. The plug part may in particular have insertion ends of different lengths. All insertion ends of the plug part advantageously have the same length. Thus, a high efficiency in terms of time and/or cost during plugging can advantageously be achieved.

In particular when the total length of the region with the insertion end is at most 100 × N × d (where N is the number of longitudinal elements of the cable), a lower material requirement in terms of jacket material and in particular a lower production complexity can be achieved. The total length of the region with the insertion end is advantageously at most 80 × N × d, particularly advantageously at most 60 × N × d, preferably at most 50 × N × d, and particularly preferably at most 40 × N × d. In particular, at least part of the regions with the insertion ends are preferably arranged in the longitudinal direction of the cable section, preferably directly adjacent to each other. All areas with an insertion end can advantageously be arranged preferably directly adjacent to each other. In particular, the total length of the region with the insertion end can at least substantially correspond to the length of the plug part.

It is furthermore proposed that the plug-in part has at least one, preferably exactly one, intermediate region which is arranged between the insertion ends and contains at least one part of the core and/or the in particular non-metallic substitute element. The replacement element herein is particularly useful for replacing the core. The replacement element may be made at least partially of plastic and/or rubber, for example. The cross section of the displacing element preferably at least substantially corresponds to the cross section of the core. The intermediate region is advantageously arranged in the center of the plug part. The front half sections of all insertion ends of the plug part are particularly advantageously arranged in front of the middle region and the rear half sections of all insertion ends of the plug part are particularly advantageously arranged behind the middle region, as viewed in the longitudinal direction of the cable section. The intermediate zone has in particular a length of at least 100 x d and advantageously of at least 200 x d. In the case of a length of the plug part of more than 600 × d, the length of the plug part can advantageously consist of the total length of the region with the insertion end and the length of the intermediate region. The length may amount in particular to a plug-in part length of 1200 × d, in particular for reasons of compliance with predetermined criteria, wherein other and advantageously greater lengths are of course also conceivable. In the case of a target length of 1200 × d for the plug part, the length of the middle region may be 600 × d, for example, and the length of the region with the insertion end may likewise be 600 × d. Likewise, the intermediate region may be lengthened accordingly and/or the region having the insertion end may be shortened accordingly. In this way, a plug-in part having a predetermined length can be produced, wherein the production complexity can be advantageously reduced by the short insertion end.

However, the plug part preferably does not have any intermediate piece of this kind, so that the plug part can advantageously be provided with a shorter overall length.

Furthermore, it is proposed that the plug part has a number 2 × N-2 of longitudinal element end regions which are located and/or inserted in particular in the interior of the plug part and are each arranged in the immediate vicinity of at least one other longitudinal element end region. Thereby, a plug-in part with an advantageously reduced overall length can be provided. Additionally, the plug part preferably comprises two longitudinal element end regions which are arranged in the closer range of the core part, in particular at opposite ends of the plug part. In this context, "closer range" is to be understood in particular as meaning regions whose length (preferably in the longitudinal direction of the cable section) is at most 20 × d, advantageously at most 10 × d, particularly advantageously at most 8 × d, preferably at most 5 × d, and particularly preferably at most 3 × d. In particular, the two longitudinal element end regions are respectively adjacent to one another in the near range. The plug part advantageously has at least one distance element which is arranged between adjacent end regions of the longitudinal elements and preferably in the interior of the plug part, instead of the core. The length of the distance elements is in particular at least 1 × d, advantageously at least 2 × d, particularly advantageously at least 3 × d, and preferably at least 4 × d and/or at most 15 × d, advantageously at most 10 × d, particularly advantageously at most 8 × d, and preferably at most 6 × d, for example a length of 5 × d. The region with the insertion end may particularly comprise distance elements, but advantageously does not comprise any potential intermediate elements. The distance elements in the longitudinal direction of the cable sections preferably abut adjacent longitudinal element end regions. This advantageously prevents a large intermediate space from being formed in the event of tensile and/or bending loads of the plug-in part. In particular, the relative movement of the end regions of adjacent longitudinal elements advantageously results in the formation of two narrow intermediate spaces, which respectively form between one of the end regions of the longitudinal element and the distance element, preferably without forming a single wider intermediate space. It is likewise conceivable that at least two, in particular two, longitudinal element end regions are respectively directly adjacent, preferably without a distance element between them. It is furthermore conceivable for the plug-in part to have at least two and advantageously 2 × N-2 longitudinal element end regions which are connected to one another in pairs. The longitudinal element end regions can be welded and/or glued to one another, for example, and/or connected to one another by at least one press fit joint, in particular except in the case of a press fit produced by the longitudinal elements surrounding the longitudinal element end regions. In this case, the two, in particular the two longitudinal element end regions each preferably adjoin one another.

Advantageously, a reliable and/or load-bearing plug-in part can be provided in particular if the end region of the longitudinal element is an end region of the insertion end. In particular in the case of a plug-in part comprising 2 × N plug-in ends, the 2 × N-2 plug-in ends preferably form 2 × N-2 longitudinal element end regions. Furthermore, the two peripheral insertion ends advantageously constitute two longitudinal element end regions adjacent to the core.

Preferably, the insertion element is configured to at least partially receive an insertion end, in particular a plain end, which is advantageously configured to form an insertion end inserted in the opposite direction, or to form a corresponding longitudinal element of the insertion end, the insertion element is preferably a dummy insertion portion (Splei β puppe). the insertion element advantageously has a plurality of further receiving regions, which extend in a helical manner and are configured to receive one longitudinal element, respectively, the insertion element particularly has N-1 further receiving regions of the type described, the insertion element is particularly configured to replace a core element of a cable in the region of the insertion position, in particular in the region of the insertion end, preferably in the region of the insertion position, preferably in the region of the insertion end, at least a core element region of a cable, which is preferably deeper than the further receiving regions, and/or is configured to replace a core element of a cable, at least two insertion elements, preferably at least two insertion regions, which are preferably configured to be at least partially inserted, preferably at least partially, and at least two insertion elements are preferably configured to be at least partially inserted, preferably at least partially, preferably, at least two insertion elements are configured to be, preferably at least partially, at least two insertion elements, preferably, at least partially, at least two insertion elements, preferably, at least two insertion elements, preferably, at least two insertion elements, or preferably, at least two insertion elements, preferably, or preferably, at least two insertion elements, preferably, at least two, or preferably, at least two insertion elements, preferably, at least two, preferably, substantially, preferably, substantially, or substantially, preferably substantially, preferably substantially, substantially.

Furthermore, it is proposed that the insertion end has an undulation (Welligkeit) with a magnitude corresponding to at least 0.5% and/or at most 20% of the magnitude of the undulation of the longitudinal element, in particular in a portion of the longitudinal element which is different from the insertion end and which is preferably arranged outside the interior of the plug portion and/or outside the plug junction region. Advantageously, the longitudinal element is at least partially straightened in the region of the insertion end. The undulations correspond in particular to deviations from a straight profile. The amplitudes here may be the amplitudes of the contours of the insertion end or the longitudinal element, respectively, when viewed perpendicular to the longitudinal direction of the insertion end, or the amplitudes of the longitudinal element, respectively, and/or the corresponding amplitudes in a projection perpendicular to the longitudinal direction of the insertion end or the longitudinal element, respectively. The insertion end and the longitudinal element are preferably undulating in at least two perpendicular spatial directions. The insertion end and the longitudinal element particularly preferably conform to a spiral and/or spiral contour, respectively, wherein the contour of the insertion end can advantageously be produced from the contour of the longitudinal element at least by stretching the contour of the longitudinal element in the longitudinal direction. The amplitude of the undulations of the insertion end advantageously corresponds to at least 1%, particularly advantageously at least 2%, and preferably at least 3%, and/or at most 15%, particularly advantageously at most 10%, and preferably at most 8% of the amplitude of the undulations of the longitudinal elements. The internal geometry of the plug-in part can thus advantageously be adjusted in a precise manner.

In a further embodiment of the invention, it is proposed that the plug-in part has at least one further insertion end, the length of which differs from the length of the insertion end. A high degree of variability in the embodiment of the plug-in part can thus be advantageously achieved. Furthermore, the load-bearing properties of the plug-in part can be adjusted precisely. The plug part may in particular have insertion ends of different lengths. The insertion end and the further insertion end can be formed by different longitudinal elements, which can furthermore differ from one another, for example with respect to at least one property, for example with respect to cross section, diameter, material, laying length, etc. The length of the insertion end can be selected in particular according to the conditions of the longitudinal element. It is conceivable that the insertion ends of the individual plugging locations have different lengths. In this way, regions of different length can advantageously be produced, each having two adjacent insertion ends, wherein the adjacent insertion ends can have the same length. It is likewise conceivable for the insertion ends, which each form an insertion connection, to have the same length. In particular in this case, the two adjacent insertion ends arranged between two plugging locations can have different lengths. In particular in the case of a plug-in part having end regions of longitudinal elements which are butted and/or connected (e.g. welded) on a surface thereof and which form only part of the longitudinal elements, the longer insertion end may for example be arranged in a region in which the end regions of the longitudinal elements are butted and/or connected (e.g. welded) on a surface of the plug-in part, so that a load-bearing and compact plug-in part may advantageously be provided.

It is furthermore proposed that the plug part has a plurality of plug locations which are not separated in particular by intermediate regions and/or alternative elements, but are arranged at irregular intervals in particular in addition to potential plug locations, whereby the intermediate regions are separated by irregular intervals between the intermediate regions, whereby a high degree of variability in the adjustment of the local load-bearing capacity of the plug part can be achieved.

Alternatively, it is proposed that the plug part has a plurality of plug positions arranged at least substantially regular intervals. This advantageously makes it possible to provide a plug part which can be produced in a simple and reliable manner. Furthermore, particularly for multi-strand cables having identical longitudinal elements, it is possible to provide the plug part with an evenly distributed local load-bearing capacity. All the plug positions of the plug part are preferably arranged at regular intervals. In particular in the case of a plug-in part having at least one intermediate region, it is conceivable for the plug-in positions of the plug-in part to be arranged in groups, with regular spacings between the plug-in positions.

In an advantageous embodiment of the invention, it is proposed that in at least one test, the test insertion end in the pretensioned state and under tensile load, a test cable element of a cable having a diameter d and at least one test insertion end can surround at least one test disc having a diameter of at most 80 × d, advantageously at most 60 × d, and particularly advantageously at most 40 × d, in particular in each case at least 90 × dThe bending is carried out at least 1000 times, advantageously at least 2000 times, particularly advantageously at least 5000 times, preferably at least 10,000 times, and particularly preferably at least 15,000 times without damage, advantageously at 120 ° each, and preferably at 150 ° each. In particular, the length of the portion of the test insertion end inserted into the test cabling is at most 50 × d, advantageously at most 40 × d, and particularly advantageously at most 30 × d. In particular, the test cable piece under test may be able to bend around two opposite test trays, which are advantageously bent in opposite directions to a specified angle as a total angle, thus for example at an angle of 45 ° around the first test tray and at an angle of 45 ° around the second test tray, respectively, in an alternating manner without being damaged. The test insertion end is advantageously constructed in a similar manner to the insertion end of the cable section and is in particular covered with a sheathing material. Furthermore, the test cable piece is advantageously constructed in a manner similar to a cable. It is envisaged that the test cabling comprises a plurality of insertion ends. It is furthermore conceivable for the test cable piece to comprise the entire test plug section. Advantageously, the test cable element comprises only one test insertion end, at one end of which it is preferably inserted inside the test cable element, replacing the core of the latter. A high mechanical reliability and/or load-bearing capacity of the plug part can thereby be advantageously achieved. Furthermore, a compact plug-in part can advantageously be provided with a high service life. A test cable piece which is "bendable without damage" should be understood in particular as: in particular after the test experiment has been performed, preferably in a pre-tensioned state of the test insertion end and/or the test cable piece (e.g. a pre-tensioning force of at least 60N/mm per cross-section a of the test cable piece)²Preferably at least 250N/mm²And advantageously at least 500N/mm²At times), the test insertion end and/or the plurality of test insertion ends of the test piece of cable remain inert. The expression "remaining inert" should be understood in particular as: under the effect of the pretensioning force, the test cable piece is at least substantially free from any slippage and/or any indentation of the test insertion end, in particular with respect to the remaining section of the test cable piece. The test cable "substantially without any sag and/or any slippage" should be especially understoodComprises the following steps: after performing the test experiment, the extent of any recess and/or any slippage of the test insertion end (in particular with respect to the remaining section of the test cable piece) is less than the diameter of the test cable piece, preferably less than half the diameter of the test cable piece, preferably less than a quarter of the diameter of the test cable piece, and particularly preferably less than the diameter of the core of the test cable piece.

In the case of combined bending and tensile loads, for example in the operation of a cableway, if test cable pieces are used in the test experiments at least 60N/mm²Advantageously at least 100N/mm²Advantageously at least 200N/mm²Preferably at least 300N/mm²Particularly preferably at least 500N/mm²Pretensioning of the test cable section per cross section a, in particular in the case of a six-strand cable, then a reliable and durable plug-in part can be provided in particular.

If the test insertion end is subjected to an extraction force in kN in a test run, the extraction force is at least d²0.68/N0.04, advantageously at least d²0.68/N0.1, particularly advantageously at least d²0.68/N0.2, preferably at least d²0.68/N0.4, particularly preferably at least d²0.68/N0.6, it is then possible in particular to provide a load-bearing and reliable plug-in part with a short insertion end, which can advantageously be manufactured in a simple and/or rapid manner. The insertion member preferably withstands the same extraction force as the test insertion end. Each plug-in element of the plug-in part is particularly preferably subjected to the same withdrawal force as the test plug-in end. In particular, the pull-out force in the test experiment acts parallel or at least substantially parallel to the longitudinal direction of the test cable piece and/or the test insertion end. In particular, the test insertion end in the test experiment is subjected to a pulling-out force in a longitudinal direction of the test insertion end.

The invention further relates to a cable forming a multi-strand cable for people transportation, having at least one longitudinal element, in particular a strand, which is configured to form at least one insertion end of a plug section, in particular a long plug section, of a cable section according to the invention. In accordance with the present inventionIn the case of cables according to (1), such advantageous properties can be achieved, in particular a particularly compact and load-bearing plug part which is easy to manufacture, in particular for manufacturing a continuous cable from a cable. The cable is advantageously implemented as a cableway cable. However, it is also conceivable that the cable is a transport cableway cable, in particular a material transport multi-strand cable. The cable is advantageously configured to be used as a main cable for manufacturing a continuous cable, in particular a haul cable and/or a haul cable. The cable particularly has a preferably constant diameter d, wherein for example the diameter d may be in the range of the values mentioned above. The cable preferably has a number N of longitudinal elements, which are in particular embodied identical to one another. As mentioned above, N is advantageously 6, but may also be 5, 7, 8, 9, 10, 11 or 12, for example. A greater number of longitudinal elements may also be considered. The cable preferably has at least one core, advantageously exactly one core, around which the longitudinal elements are stranded.

The invention further comprises a cable which forms a multi-strand cable for the transport of persons and which is configured to be plugged by means of at least one plug-in part which is embodied as a long plug-in part of a cable section. In the case of the cable according to the invention, such advantageous properties can be achieved that a particularly compact and load-bearing plug part, in particular for the production of a continuous cable from a cable, is easy to produce. The cable is advantageously implemented as a cableway cable. However, it is also conceivable that the cable is a transport cableway cable, in particular a material transport multi-strand cable. The cable is advantageously configured to be used as a main cable for manufacturing a continuous cable, in particular a haul cable and/or a haul cable.

The advantageous property of producing a reliable plug part, in particular a long plug part, in particular in a fast manner and/or in a relatively compact space, can be achieved in particular by a cable, in particular a continuous cable, having at least one cable section according to the invention. The cable is advantageously a multi-strand cable. The cable is particularly advantageously a traction cable and/or a haulage cable, in particular a cable of a cableway, advantageously a cable of a passenger cableway, preferably a cable of a city cable car and/or a mountain cable car. The cable is in particular a multi-strand cable for personnel transport, preferably a city cable car multi-strand cable and/or a mountain cable car multi-strand cable. It is of course also conceivable that the cable is a material runway, in particular a hauling cable and/or a hauling cable of a material transport system.

Furthermore, a use of at least one cable according to the invention with at least one cable section according to the invention is proposed for hauling cables and/or hauling cables, in particular in passenger cableways, advantageously in passenger cableways, preferably in mountain trolleys and/or city trolleys. However, the use as a hauling cable and/or a hauling cable in a material ropeway or any other type of ropeway is equally conceivable.

According to a further aspect of the invention, which may be considered alone or in combination with at least one further aspect of the invention, in particular in combination with one or more further aspects of the invention, a method is proposed for splicing a cable forming a multi-strand cable for people transport, the cable having a diameter d, preferably for producing a continuous cable, in particular a cable according to the invention having at least one cable section according to the invention, which is advantageously used for passenger ropeways, for example for mountain and/or city cable cars, or else for material ropeways having a plurality of twisted longitudinal elements.

It is proposed that, for the production of at least one plug part embodied as a long plug part, at least one end region of at least one longitudinal element, in particular instead of a core, is inserted as an insertion end between other longitudinal elements of a length of at most 50 x d.

Thus, according to the method of the invention, advantageous properties of manufacturing a socket, in particular a long socket, can be achieved. Furthermore, the complexity of manufacturing the plug part, in particular the insertion end of a long plug part, can advantageously be reduced. Furthermore, a plug part, in particular a long plug part, can advantageously be provided, which has a short insertion end which is easy to produce. Cost-effective efficiency can advantageously be achieved, in particular while achieving high reliability of the finished plug part, in particular of the long plug part. In particular, the short time required for plugging can be achieved. Furthermore, a compact socket, in particular a long socket, can be provided which can withstand the load. Furthermore, the plug-in connection, in particular of a long plug-in part, can advantageously be realized in a compact space and/or over a short length. In particular, the length of the plug connection region which is handled in a complicated manner can be advantageously reduced, in particular by means of the long plug section.

The insertion end is advantageously inserted between the other longitudinal elements over a length of at most 40 × d, particularly advantageously at most 30 × d, preferably at most 25 × d, and particularly preferably at most 20 × d. Furthermore, the length of insertion by the insertion end can advantageously be reduced by at least half the length of the insertion joint. The insertion end is preferably covered with a jacket material prior to insertion. Advantageously, a plurality of insertion ends, in particular all insertion ends, of the plug part are inserted by a corresponding length of at most 50 x d.

According to a further aspect of the invention, which may be considered alone or in combination with at least one further aspect of the invention, in particular in combination with one or more further aspects of the invention, a method is proposed for splicing cables forming a multi-strand cable for people transportation, said cable having a diameter d, and preferably for producing a continuous cable, in particular a cable according to the invention having at least one cable section according to the invention, advantageously for passenger cableways, for example for mountain and/or city cable cars, or additionally for material cableways having N twisted longitudinal elements.

It is proposed to produce sockets, in particular long sockets, having a total length of at most 100 XNxd.

According to the method of the invention, advantageous properties of producing a plug part, in particular a long plug part, can be achieved. Cost-effective efficiency can advantageously be achieved, in particular while achieving high reliability of the finished plug part, in particular of the long plug part. Furthermore, a compact plug-in part, in particular a long plug-in part, can be provided. Furthermore, a short, load-bearing plug-in connection, in particular of a long plug-in part, can still advantageously be provided. For a plug part, in particular a long plug part, a low complexity in terms of production can advantageously be achieved. Furthermore, the plug-in connection, in particular of a long plug-in part, can also be achieved if the available space is significantly limited, in particular if the length of the region available for plug-in connection is short. Furthermore, a low complexity of the production and production of the plug-in part, in particular of the long plug-in part, can be achieved.

A plug part is advantageously produced, the total length of which is at most 80 × N × d, particularly advantageously at most 60 × N × d, preferably at most 50 × N × d, and particularly preferably at most 40 × N × d. In particular in the case of a six-stranded cable, for example, a plug part is produced, the length of which is at most 600 × d, advantageously at most 500 × d, particularly advantageously at most 400 × d, preferably at most 300 × d, and particularly preferably at most 250 × d.

It is furthermore proposed that the plug part embodied as a long plug part is produced in one piece without the plug part being advanced in an incomplete state in a region of a length of at most 1200 × d, advantageously at most 1000 × d, particularly advantageously at most 800 × d, and preferably at most 600 × d. In the context of this document, "advancing" is to be understood in particular as a pushing and/or pulling of the plug part in the incomplete state, in particular in the longitudinal direction of the cable. In particular, advancing may be understood as moving an unfinished, finished sub-section out of the processing area, in particular in combination with a displacement of a not yet finished further sub-section of an unfinished plug section into the processing area. Said area may for example be located in a downhill station, an uphill station, a cableway station, etc. having in particular a limited available space, for example a limited length. The entire plug-in part, in particular the long plug-in part, is produced in particular in one piece and/or in the region without any advance. Thereby reducing production complexity. Furthermore, the plug-in connection, in particular, which is embodied as a long plug-in connection, can be realized in narrow spaces, for example in narrow stations, in particular cable station stations, for example on cities and/or hills and/or mountains, wherein the available space is limited.

The cable section according to the invention and the method according to the invention for plugging a cable are not limited to the above-described applications and embodiments. The cable section according to the invention and the method according to the invention for fulfilling the functional modes described herein can in particular have a plurality of individual elements, components, units and method steps differing from the numbers mentioned herein and/or having any meaningful combination of said individual elements, components, units and method steps.

Detailed Description

Fig. 1 shows a schematic view of a passenger cableway 92a with cables 12 a; the cable 12a is formed as a multi-strand cable for personnel transportation. The passenger cableway 92a is a cableway. The passenger cableway 92a may be, for example, a mountain cable car. Passenger cableway 92a is advantageously a city cable car. It is conceivable in this context that the passenger cableway covers a height difference. It is also contemplated that the passenger cableway 92a extends at least in a substantially horizontal manner. The passenger cableway 92a may have a support tower (not shown). Furthermore, the passenger cableway 92a may have a plurality of sections with different gradients, in particular sections with a positive gradient and sections with a negative gradient. It is further contemplated that passenger cableway 92a extends at least partially underground. In the present case, the cable 12a is a haul cable. The cable 12a serves as a haul cable in the passenger cableway 92 a. It is likewise conceivable to use the pull cable, in particular in addition to a separate suspension cable. In principle, it is also conceivable for the cable 12a to be a section of a material runway, in particular a section of a material mountain runway and/or a material city runway. The cable 12a may generally be used as a pulling cable and/or a haul cable in a cableway and/or may be used as a section of said pulling cable and/or haul cable.

The cable 12a is in the present case a multi-strand cable, in particular a multi-strand cable. However, the cable 12a may be at least partially realized as a plastic material cable and/or a composite material cable or the like. The cable 12a has at least one cable section 10a with at least one plug-in connection 14 a. In the present case, the socket 14a is a long socket. Furthermore, in the present case, the socket 14a is a multi-strand cable socket. The plug part 14a is realized at least in part, in particular, in the form of a long plug part. The cable 12a is a continuous cable. The cable 12a is in particular a continuous cable plugged by a plug part 14 a. The cable 12a is implemented without a sheath surrounding the cable.

Fig. 2 shows a cable 90a, which is configured for plugging by means of the plug section 14a of the cable section 10 a. In the unplugged state of the cable 12a, the cable 90a corresponds in particular to the cable 12a of the passenger cableway 92 a. The cable 12a of the passenger cableway 92a, which is implemented as a continuous cable, can be produced by plugging the cable 90 a. For example, the cable 90a wound on the drum is transported to the installation site, particularly the site of the passenger cableway 92a, and spliced thereto. The manufacture of the cable 90a herein may be performed at another location, for example, in a cable plant.

Fig. 3 shows a schematic cross-sectional view of a cable section 10 a. In particular, fig. 3 shows a different region of the cable section 10a than the plug section 14 a. The cross section of the cable 12a is realized in a corresponding manner. The cable segment 10a, and in particular the cable 12a, has N longitudinal elements 16a-26 a. In the present case, N is 6. As mentioned above, however, any other number of longitudinal elements 16a-26a, in particular five, seven, eight, ten, twelve, or even more, may be envisaged. In the present case, the longitudinal elements 16a-26a are strands, in particular silk strands. Stranded wires are equally conceivable, or else individual wires, composite wires, core/shell longitudinal elements, etc.

In the present case, the longitudinal elements 16a-26a are realized at least substantially identical to each other, or identical to each other. The longitudinal elements 16a-26a particularly have at least substantially the same, or the same, cross-section. Furthermore, the longitudinal elements 16a-26a may have at least substantially the same, or the same, lay length and/or lay direction. The cable 12a may be a regular lying cable, and preferably a lanss lying cable. In principle, it is conceivable for the cable section 10a and/or the cable 12a to have differently embodied longitudinal elements 16a-26a, which differ, for example, in terms of cross section, material, tensile strength, laying length, laying direction, etc. The longitudinal elements 16a-26a are realized without a sheath surrounding at least one of the longitudinal elements 16a-26 a.

The cable 12a and in the present case at least one peripheral region of the cable section 10a have a core 94 a. The core 94a may be made at least partially of plastic, for example. The longitudinal elements 16a-26a are arranged around the core 94a, in particular at regular intervals. The longitudinal elements 16a-26a extend around the core 94a, in particular in a helical manner. The longitudinal members 16a-26a are twisted about the core 94 a.

In the present case, the cross-section of the core 94a is larger than the cross-section of the longitudinal elements 16a-26 a. Furthermore, the core 94a advantageously has a cross section with segmented gaps and/or indentations for the longitudinal elements 16a-26a, which advantageously follow a helical profile around the core 94a, depending on the twisting of the longitudinal elements 16a-26 a.

The longitudinal elements 16a-26a are advantageously arranged around the core 94a in such a way that the longitudinal elements 16a-26a do not touch each other at least on the outside of the plug part 14 a. In particular, the longitudinal sides of the longitudinal elements 16a-26a are arranged not to contact each other at least outside the plug part 14 a. In addition, it is conceivable to arrange longitudinal inserts between the longitudinal elements 16a-26a, which extend in particular around the core 94a so as to be parallel to said longitudinal elements 16a-26a and advantageously establish the spacing between the longitudinal elements 16a-26 a. Such longitudinal inserts are advantageously made of a material that is softer than the material of the longitudinal elements 16a-26a, for example made of plastic, rubber, composite material or the like. Furthermore, at least one, in particular a plurality of or all of the cable 12a or the cable section 10a and/or the longitudinal elements 16a to 26a, respectively, may have at least one coating, for example an anti-corrosion coating and/or a plastic covering or the like.

The cable section 10a, and in particular the cable 12a, has a diameter d. In particular, the diameter d corresponds to the diameter of the smallest circle (in particular its cross section) that surrounds the cable section 10 a. The cable 12a is in the present case a round cable, in particular a round cable. However, it is also conceivable in principle for the cable 12a to be polygonal or oval. In the present case, the diameter d may be 70mm, for example, wherein any other diameter may be envisaged, as described above.

Fig. 4 shows a schematic view of a cable section 10a of a cable 12a with a plug-in connection 14 a. For visualization reasons, the longitudinal elements 16a-26a in fig. 4 are placed parallel and side by side to each other, but said longitudinal elements 16a-26a may be twisted and/or extended in a helical manner around the core 94a, as already mentioned. The illustration of the cable section 10a, and in particular of the plug-in part 14a in fig. 4, is therefore to be understood as a plug-in diagram and does not necessarily represent the actual geometry of the cable section 10a and/or of the plug-in part 14a thereof.

At least one of the longitudinal elements 16a has at least one insertion end 28a which is at least partially inserted between the other longitudinal elements 16a-26 a. The insertion end 28a is inserted between the longitudinal members 16a-26a in place of the core 94 a.

In the present case, all longitudinal elements 16a-26a have two insertion ends 28a-50a, respectively. The insertion ends 28a-50a are inserted in the manner of long spigots instead of the core 94 a. The plug part 14a comprises in particular twelve insertion ends 28a-50a, wherein a further number of insertion ends is conceivable, in particular if the number of longitudinal elements of the cable deviates from six.

The cable section 10a has sections 114a, 116a of the core 94a in its peripheral region. In the present case, the sections 114a, 116a of the core 94a delimit the plug section 14 a.

The insertion end 28a has a length of at most 50 x d. In the present case, the insertion end 28a has a length of, for example, 40 × d, wherein other lengths are also conceivable, as mentioned above.

Furthermore, the longitudinal elements 16a-26a have at least one insertion end 28a-50a, respectively, with a length of at most 50 × d. In the case shown, each longitudinal element 16a-26a has two insertion ends 28a-50a, which have a length of at most 50 × d, for example respectively 40 × d.

The plug section 14a has at least one plug position 84 a. Fig. 5 shows a schematic longitudinal section of the plug position 84a of the plug part 14 a. The plug-in position 84a is shown here only in a schematic manner, wherein the length ratio in particular may not necessarily be reproduced correctly. The plugging location 84a includes a plugging junction 120 a. The plugging location 84a also includes two insertion ends 28a, 38a that are inserted in opposite directions.

In the present case, the insertion ends 28a, 38a each extend from the center 122a of the bayonet joint 120a to the insertion end of the insertion ends 28a, 38a, which are not shown in fig. 5. The insertion ends 28a, 38a in this context may each have an insertion section and a section arranged on the surface of the plug section 14a, the latter in particular forming a section of the plug connection 120 a. In the present case, the longitudinal elements 16a to 26a, which comprise the insertion ends 28a, 38a in the region of the plug-in junction 120a, are furthermore coextensive in a known manner on the surface of the plug-in part 14 a. In the present case, the longitudinal elements 16a-26a cross each other. The insertion junctions 120a are in particular flat junctions.

The insertion end 28a has an undulation with a magnitude corresponding to at least 0.5% and/or at most 20% of the amplitude of the undulation of the longitudinal elements 16a-26a, in particular outside the plugging location 84 a. For example, the amplitude of the undulations of the insertion end 28a may be 2%, wherein other values are also contemplated, as described above. The undulations of the insert element 28a are generated by the undulations of the longitudinal element 16a, in particular by twisting of the longitudinal element, by stretching and/or straightening of the longitudinal element 16 a. Due to the schematic straight line illustration of the insertion end 28a, its undulations are not shown in fig. 5. The undulation of the insertion end 28a, in particular when viewed perpendicularly to the longitudinal direction 118a of the cable section 10a, leads to a wavy, in particular sinusoidal, contour of the insertion end 28 a. In this illustration, the wavelength of the undulations of the insertion end 28a is advantageously greater than the wavelength of the undulations of the longitudinal elements 16a outside the plug-in position 84a, the latter wavelength corresponding in particular to the laying length of the longitudinal elements 16 a. In a manner similar to the undulations of the longitudinal elements 16a, the undulations of the insertion element 28a are the result of a helical profile, wherein the helical profile of the insertion end 28a is formed from the helical profile of the longitudinal elements 16a (by stretching and/or straightening the latter). In particular, when the plug part 14a is produced, the insertion end 28a is straightened out before insertion.

In the present case, the plug-in position 84a furthermore has at least one plug-in element 86a which is configured to at least partially receive the plug-in ends 28a, 30a inserted in opposite directions. The insertion element 86a in fig. 5 is only schematically indicated. Fig. 6 shows a schematic cross-sectional view of a plug connection 120a with a plug location 84a of a plug element 86 a. Fig. 8 shows a schematic perspective view of the plug-in element 86a of the plug-in position 84 a. In the present case, the plug-in element 86a is a pseudo plug. The insert element 86a is advantageously made of plastic, in particular polyethylene, wherein alternatively or additionally other materials, for example rubber, fibre composite materials, preferably soft metals such as aluminum, etc., are also conceivable. The insert element 86a is particularly advantageously a 3D printed component, in particular a plastic component.

The insertion element 86a has at least one receiving region 88a which is configured to at least partially receive the insertion ends 28a, 30a inserted in opposite directions. The receiving region 88a is implemented as a channel-type recess. The receiving areas 88a are particularly configured for at least partially receiving two longitudinal elements 16a-26a positioned to form an insert junction 120 a. The receiving area 88a may have a variable cross section along its longitudinal direction.

The insert member 86a has at least one additional receiving area 124a configured to at least partially receive the longitudinal members 16a-26 a. In the present case, the insert element 86a has a plurality of further receiving regions 124a, of which only one is provided with a reference symbol for the sake of clarity. The insert element 86a advantageously has N-1 additional receiving areas 124 a. In the region of the bayonet joint 120a, the insert element 88a is placed between the longitudinal elements 16a-26a instead of the core 94 a. The insertion element 88a is realized in particular in the following manner: in the region of the plug-in position 84a and in particular in the region of the plug-in junction 120a, the diameter of the cable section 10a is at most 8% and advantageously at most 5% greater than the nominal diameter of the cable 12 a.

The plug-in element 86a advantageously has a length which corresponds at least to the length of the plug-in knot 120 a. The receiving region 88a is preferably configured for receiving an insertion end 28a, 38a or a longitudinal element 16a-26a forming an insertion joint 120a, at least over the entire length of the insertion end 28a, 38a or a section of the longitudinal element 16a-26a, respectively, which is arranged on the surface of the insertion part 14 a.

Reference is again made to fig. 4 below. The overall length of the plug part 14a is at most 100 × N × d. In the present case, the overall length of the plug part 14a is at most 600 × d. The overall length of the plug-in part 14a corresponds to the degree of the section between the sections 114a, 116a of the core 94a in the longitudinal direction 118a of the core section 10 a. In the present case, the overall length of the plug part 14a is approximately 530 × d, wherein, as mentioned above, other overall lengths are also conceivable.

In addition, the total length of the region 76a having the insertion ends 28a-50a is at most 100 × N × d. In the present case, the total length of the region 75a with the insertion ends 28a-50a corresponds to the total length of the plug part 14 a. The plug part 14a is in particular free of regions, in particular having a length of at least 10 × d, without the insertion ends 28a-50 a.

The plug section 14a has a plurality of plug locations 84a, 104a-112a arranged at least substantially regular intervals. In the present case, all plugging positions 84a, 104a-112a of the plug part are arranged at regular intervals. The spacings between directly adjacent plug locations 84a, 104a-112a, respectively, are at least substantially identical or identical, in particular by means of the same length of the insertion ends 28a-50 a.

In the case shown, the plug part 14a has a number of 2N-2, which is to be understood as purely exemplary, with a number of ten longitudinal element end regions 52a-70a, which are each arranged within a short distance of at least one other longitudinal element end region 52a-70 a. In the present case, the longitudinal element end regions 52a-70a, respectively, are arranged adjacent to one another in pairs. The spacing between adjacent longitudinal element end regions 52a-70a herein is advantageously at most 10 × d, and particularly advantageously at most 5 × d. Furthermore, the docking locations 84a, 104a-112a are disposed adjacent to one another.

The longitudinal element end regions 52a-70a are end regions of the insertion ends 26a, 28a, 32a-48 a. In the illustrated case, all of the non-peripheral insertion ends 26a, 28a, 32a-48a each have 2N-2 longitudinal element end regions 52a-70 a.

The plug-in part 14a furthermore has at least one peripheral longitudinal element end region 126 a. Peripheral longitudinal member end region 126a is an end region of peripheral insertion end 30 a. The peripheral longitudinal element end region 126a is disposed within a close range of the core 94 a. In particular, the peripheral longitudinal element end region 126a is disposed immediately adjacent the core 94 a. Furthermore, the plug-in part 14a has in the present case at least one further peripheral longitudinal element end region 128 a. The peripheral longitudinal element end region 126a and the further peripheral longitudinal element end region 128a are arranged on opposite sides of the plug section 14a, in particular with respect to the longitudinal direction 118a of the cable section 10 a.

Fig. 8 illustrates a schematic longitudinal cross section of a part of the socket 14 a. Two adjacent longitudinal element end regions 56a, 58a are arranged in close proximity to each other. In the present case, the spacing between the longitudinal element end regions 56a, 58a is about 5 × d. As mentioned above, however, smaller or larger spacings are also contemplated.

The plug-in part 14a has at least one distance element 130a in the present case. The distance element is arranged between the longitudinal element end regions 56a, 58a, in particular inside the plug section 14a and advantageously replaces the core 94 a. In the present case, the distance element 130a is realized from plastic. However, other materials, such as rubber, soft metals, composites, fiber composites, and the like, are also contemplated, alternatively or additionally.

Adjacent longitudinal element end regions 56a, 58a are directly contiguous with the distance element 130 a. Between the distance element 130a and the adjacent longitudinal element end regions 56a, 58a, in each case, a gap 132a, 134a is provided, which can be expanded at least temporarily in the event of tensile and/or bending loads on the articulation 14 a. By means of the distance element 130a, two smaller gaps 132a, 134a are created instead of one larger gap by means of the relative movement of the end regions 56a, 58 of adjacent longitudinal elements.

In the present case, one distance element 130a is arranged between two adjacent longitudinal element end regions 52a-70a of a pair of adjacent 2 × N-2 longitudinal element end regions 52a-70a, respectively. However, for reasons of clarity, the distance elements 130a are not shown in fig. 3.

In principle, it is likewise conceivable that adjacent longitudinal element end regions 52a-70a are arranged directly adjacent to one another, in particular without distance elements being arranged between them. In this case, in particular in the unstressed state of the plug section 14a, the spacing between adjacent longitudinal element end regions 52a-70a may in particular be less than 1 × d and advantageously at most a few millimeters.

Furthermore, in the present case, at least one insertion end 28a of the plug part 14a is covered with a sheathing material 136 a. The jacket material 136a may be, for example, a plug-in strip. The insertion end 28a is advantageously covered with a sheathing material 136a in such a way that the diameter of said insertion end 28a is increased in such a way that said diameter at least substantially corresponds to the diameter of the core 94 a. The longitudinal members 16a-26a surrounding the insertion end 28a correspondingly grip the insertion end in a manner that ensures sufficient pullout force. In the present case, all insertion ends 28a-50a of the plug part 14a are covered with the sheathing material 136 a.

Fig. 9 shows a schematic view of a test cable piece 98a of a cable 12a in a test experiment. The test cable part 98a has, in sections, the same structure as the cable 12a, in particular in a different region from the cable section 10a, and is advantageously not plugged in. In addition, test cable piece 98a has at least one test insertion end 100 a. In the present case, test cable piece 98a has exactly one test insertion end 100 a. Instead of a core (not shown) of the test cable piece 98a, a test insertion end 100a is inserted at one end between longitudinal elements (not separately shown) of the test cable piece 98 a.

The test insertion end 100a is advantageously implemented to be identical to the insertion ends 28a-50a of the mating segment 14 a. However, test insertion end 100a may be inserted into test cable piece 98a from one end thereof, rather than laterally at the plugging location. In principle, however, it is also conceivable for the test cable part 98a to comprise at least a section of the test socket or the entire test socket.

The test insertion end 100a in the test experiment is under a tensile load. Further, the test experiment was performed while the test cable piece 100a was under tensile load. In testing experiments, the test insertion end 100a was able to bend at least 1000 times around a test disc 102a having a diameter of at most 80 x d without damage.

In the present case, the test insertion end 100a can be bent, for example, about at least 90 ° and advantageously about at least 150 ° each at least 2000 times, respectively. Furthermore, the diameter of the test disc may advantageously be at most 60 × d, or at most 40 × d. For example, the rotation of the plug part 14a around the drive pulley of the cableway can be simulated by test experiments. The insertion ends 28a-50a of the mating portion 14a are implemented in such a way that a test insertion end 100a, which is implemented identically to the insertion ends 28a-50a, is subjected to the described test experiments without being damaged.

In the test experiment, the test cable piece 98a passes at least 60N/mm per cross-sectional area A²The pre-stretching force of (a). In the test experiments, the test cable part 98a particularly advantageously passes through at least 500N/mm per cross-sectional area A²The pretensioning force is advantageously used for pretensioning.

In a test experiment, the test insertion end 100a withstands at least d²0.68/N0.1 extraction force in kN. The test insertion end 100a advantageously withstands at least d²0.68/N0.2, and particularly advantageously at least d²0.68/N0.4 extraction force. In the present case, each of the insertion ends 28a-50a of the plug part is subjected to a correspondingly high withdrawal force.

Fig. 10 shows a schematic flow diagram of a first method for plugging a cable 90a (see fig. 2), in which in particular the cable 12a of a passenger cableway 92a (see fig. 1) is produced. In a first method step 138a, a cable 90a (e.g., a cable delivered to a location of a passenger cableway 92a) having a diameter d (particularly a nominal diameter d) with a plurality of twisted longitudinal members 16a-26a is provided. In a second method step 140a, the plug-in part 14a is produced by plugging in the cable 90 a. For manufacturing the plug-in part, at least one end region of at least one of the longitudinal elements 16a-26a is inserted as an insertion end 28a-50a over a length of at most 50 d (for example over a length of at most 40 d) between the other longitudinal elements 16a-26 a. In the present case, all insertion ends 28a-50a are each inserted over a length of at most 50 × d, for example over a length of at most 40 × d.

In a second method step 140a, the plug part 14a is advantageously produced in one piece in a region 96a of length at most 1200 × d (see also fig. 1). In particular, the socket 14a is manufactured without advancing the socket 14a in an incomplete state. In the present case, the length of the region 96a is at most 900 × d and advantageously at most 700 × d. In particular, the region 96a may in particular only have the largest space available for plugging, for example in the case of limited space in the cableway station 146a of the passenger cableway 92 a.

Fig. 11 shows a schematic flow diagram of a second method for plugging a cable 90a, in which in particular a cable 12a of a passenger cableway 92a (see fig. 1) is produced. In the present case, the first method and the second method are the same. In particular, the first method may comprise at least a section of the second method, or vice versa. In a first method step 142a, a cable 90a (e.g., a cable delivered to a location of a passenger cableway 92a) having a diameter d (particularly a nominal diameter d) with a plurality of N-stranded longitudinal members 16a-26a is provided. In a second method step 144a, the plug-in part 14a is produced by plugging in the cable 90 a. In a second method step 144a, the plug part 14a is produced in such a way that the total length of the plug part 14a is at most 100 × N × d. In the present case, the plug part 14a is manufactured with an overall length of at most 530 x d. In this context, the overall length of the plug-in part 14a is composed in particular of the sum of the lengths of the insertion ends 28a to 50a and of the distance element 130 a.

In a second method step 144a, the plug part 14a is advantageously produced in one piece in a region 96a of length at most 1200 × d (see also fig. 1). In particular, the socket 14a is manufactured without advancing the socket 14a in an incomplete state. In the present case, the length of the region 96a is at most 900 × d and advantageously at most 700 × d. In particular, the region 96a may in particular only have the largest space available for plugging, for example in the case of limited space in the cableway station 146a of the passenger cableway 92 a.

Fig. 12 to 14 show further exemplary embodiments of the present invention. The following description is essentially limited to the points of distinction between exemplary embodiments, wherein reference to unmodified components, features and functions may be made according to the description of the exemplary embodiments of fig. 1 to 11. To distinguish the exemplary embodiments, the suffix a in the reference numerals of the exemplary embodiments in fig. 1 to 11 has been replaced with the suffixes b to d in the reference numerals of the exemplary embodiments in fig. 12 to 14. As far as the unmodified components, in particular components having the same reference numerals, reference may in principle be made to the figures and/or the description of the exemplary embodiments of fig. 1 to 11.

Fig. 12 shows a schematic view of a first alternative cable section 10b of a cable 12b of diameter d. The cable section 10b has at least one plug-in connection 14 b. The plug portion 14b includes a number N of twisted longitudinal members 16b-26 b. At least one of the longitudinal elements 16b-26b has at least one insertion end 28b which is at least partially inserted between the other longitudinal elements 16b-26b, in particular instead of the core 94b of the cable 12 b. The insertion end 28b has a length of at most 50 x d.

The total length of the regions 76b, 78b with the insertion end 28b is at most 100 × N × d. In the present case, the plug part 14b has a first region 76b with an insertion end 28b and a second region 78b, of which only one is provided with a reference numeral for the sake of clarity. The first region 76b and the second region 78b may include the same number of insertion ends 28 b. In the present case, the first region 76b includes N insertion ends. Furthermore, in the present case, the second region 78b likewise comprises N insertion ends. The first region 76b and the second region 78b are arranged spaced apart from each other in the longitudinal direction 118b of the cable section 10 b.

The mating portion 14b has at least one intermediate region 80b disposed between the insertion ends 28 b. The intermediate region 80b contains at least a section 82b of the core 94b and/or the replacement element 148 b. In the present case, the intermediate region 80b comprises a substitute element 148b, which is advantageously made of a plastic material or another suitable material. The replacement element 148b is configured to replace the core 94b in the intermediate region 80 b. For example, the replacement element 148b may have a cross-section and/or cross-sectional profile that corresponds to the cross-section and/or cross-sectional profile of the core 94 b. Alternatively, in particular a previously cut-off section of the core 94b can be inserted into the interior of the plug part 14b instead of the replacement element 148b in the middle region 80 b.

The overall length of the plug part 14b is made up of the sum of the overall lengths of the regions 76b, 78b with the insertion end and the length of the middle region 80 b. In one aspect of the invention, it is conceivable that the total length of the plug part 14b is, for example, N × 200 × d, in particular 1200 × d, or even greater. The plug part 14b advantageously has a total length of at most N × 100 × d.

Fig. 13 shows a schematic view of a second alternative cable section 10c of a cable 12c of diameter d. The cable section 10c has at least one plug-in connection 14 c. The plug portion 14c includes a number N of twisted longitudinal members 16c-26 c. At least one of the longitudinal members 16c-26c has at least one insertion end 28 c. The insertion end 28c has a length of at most 50 x d. Furthermore, the length of the plug part 14c is at most 600 × d.

In the present case, the plug part 14c comprises a plurality of insertion ends 28c smaller than 2 × N. For the sake of clarity, only one of the insertion ends 28c in fig. 13 is provided with a reference numeral. In the present case, the plug part 14c has a number of 2 × N-4 insertion ends 28 c. Furthermore, the socket 14c has at least two (in the present case four) longitudinal element end regions 52c-58c adjoining on the surface of the socket 14 c. Furthermore, the longitudinal element end regions 52c-58c are connected to one another in pairs (in particular welded). It is likewise conceivable to insert the longitudinal element end regions 52c to 58c in pairs into the connecting sleeve in order to allow a relative displacement of the longitudinal element end regions 52c to 58c, in particular in the case of tensile and/or bending loads on the plug part.

It is also contemplated that at least one insertion end 28c has a length greater than 50 x d. In particular, it is conceivable for the length of the insertion ends 28c to be at most N × 100 × d/M, where M is the number of insertion ends 28 c. Furthermore, it is envisaged that any other (advantageously even) number of longitudinal element end regions 52c-58c are placed in abutment on the surface of the plug portion 14c and are advantageously not inserted.

Fig. 14 shows a schematic view of a third alternative cable section 10d of a cable 12d of diameter d. The cable section 10d has at least one plug-in connection 14 d. The plug portion 14d includes a number N of twisted longitudinal members 16d-26 d. At least one of the longitudinal members 16d-26d has at least one insertion end 28 d. The insertion end 28d has a length of at most 50 x d. Alternatively or additionally, the plug part 14c may have a length of at most 600 × d.

The plug part 14d has at least one further insertion end 30d, the length of which differs from the length of the insertion end 28 d. In the present case, the further insertion end 30d is longer than the insertion end 28 d. For example, the mating part 14d may have insertion ends 28d, 30d that decrease in length toward the periphery of the mating part 14 d. Likewise, any other distribution of the lengths of the insertion ends 28d, 30d is contemplated.

The mating section 14d has a plurality of mating locations 84d, 104d-112d arranged at irregular intervals. In the present case, the irregular spacing is established by the different lengths of the insertion ends 28d, 30 d. However, it is also conceivable to place distance elements of different lengths between the insertion ends 28d, 30d, in particular between insertion ends of the same length, in order to create different spacings between the plugging locations 84d, 104d-112 d.
