Description

Snop kabelskega vodnika iz množice cevi iz umetne snovi in postopek proizvodnjeA bundle of cable conductors from a plurality of plastic tubes and manufacturing process

Področje, v katero spada izumFIELD OF THE INVENTION

Področje, v katero spada izum, je snop kabelskega vodnika, ki obstoji iz množice cevi iz termoplastične umetne snovi, povezan s pomočjo integralno oblikovanih in gibkih, vzdolžno potekajočih stojin, ter ki se lahko razveže iz snopa, da tvori raven cevasti agregat, ki ima dve zunanji cevi in pri čemer so tesnilna rebra vodniškega snopa integralno oblikovana na imenovanih zunanjih ceveh, začenši od vzdolžno raztezajoče se integralne tvorne črte. Izum se nanaša tudi na postopek proizvodnje takšnih snopov kabelskega vodnika.The field of the invention is a bundle of cable conductors consisting of a plurality of thermoplastic plastic tubes connected by means of integrally formed and flexible, longitudinally extending webs and which can be unbundled to form a straight tubular assembly having two outer tubes, wherein the guide bundle sealing ribs are integrally formed on said outer tubes, starting from a longitudinally extending integral forming line. The invention also relates to a method of manufacturing such cable conductor bundles.

Tehnični problem in stanje tehnikeTechnical problem and state of the art

Snopi, kabelskega vodnika se uporabljajo za električne kable, kable optični h ' vlaken in slično in so večinoma položeni pod zemljo. Pri uporabi za polaganje v tla praviloma začno pri kabelskih jaških in tečejo v kabelske prodore, kabelske uvodnice v stavbah ali slično. Snopi kabelskih cevi, položeni v zemljo, so hkrati pot odpirajoče se nehomogenosti v tleh, ki takorekoč predstavljajo skrivne vodne poti ali celo vodne smeri za talno vodo in vdirajočo površinsko vodo, ki lahko prodira zelo moteče v kabelske jaške, kabelske uvodnice v stavbah in slično. V tem pogledu služijo tesnilna rebra kabelskega vodnika, ki se uporabljajo za znane snope kabelskega vodnika za tesnenje kabelskega snopa. Po drugi strani morajo biti snopi kabelskega vodnika zadostno fleksibilni med operacijami polaganja kablov in v položenem stanju zato, da bi sprejemali deformacije brez zlomov mod takšnimi polagalnimi operacijami in v področjih posedanja tal .The bundles, cable leads, are used for electrical cables, fiber optic h 'fibers and the like, and are mostly laid underground. When used for laying in the ground, as a rule, it starts at cable shafts and runs into cable penetrations, cable glands in buildings or the like. Bundles of cable pipes laid in the ground are at the same time a path of opening inhomogeneity in the soil, which also represents secret waterways or even waterways for groundwater and intruding surface water, which can penetrate very disturbing cable shafts, cable glands in buildings and the like. . In this respect, the cable guide sealing ribs used for the known cable guide bundles are used. On the other hand, the cable guide bundles must be sufficiently flexible during cable laying operations and in the laid-down state in order to accommodate deformation without modal fracture by such laying operations and in the areas of soil settlement.

Tesnilna rebra kabelskega vodnika na znanih snopih kabelskega vodnika (DE-GM 92 06 473), iz katerega izum izhaja, so nameščeni na takšen način, da začenjajo iz integralne tvorne črte na cevi iz umetne snovi in tangencialno tesno nasedajo na nasprotni cevi iz umetne snovi. Neposredno zvarjenje z zunanjo steno cevi je izvedeno na dotikalni črti, ki jo tako tvori tangencialno naleganje. To se je pokazalo kot koristno, vendar se je lahko izboljšalo, kar se tiča tehnike proizvodnje in funkcije. V proizvodni tehniki je moteče to, da se mora izvesti varjenje, zlasti na tenkostenih ceveh iz umetne snovi, zelo skrbno zato, da ne bi poškodovali stene cevi, na katero mora biti položen varilni šiv. če bi bil izveden, po drugi strani, var preveč skrbno, ne bi bilo jamstva za to, da je varilni šiv dovolj tesen pod bremeni, ki jih mora prenesti, če varilni šiv ni dovolj tesen, je motena tesnilna funkcija. Znani snopi kabelskega vodnika in celo cevni agregati, iz katerih so sestavljeni, so izdelani brez posebnih ukrepov po pravilih za ekstirudi ranje termoplastičnih umetnih snovi in cevnih agregatov.The cable conductor sealing ribs of known cable conductor bundles (DE-GM 92 06 473) from which the invention originates are positioned in such a way that they start from the integral forming line on the plastic tube and tangentially sit on the opposite plastic tube . Direct welding with the outer wall of the pipe is made on the touch line, which is thus formed by tangential alignment. This proved to be useful but could be improved in terms of production techniques and function. It is disturbing in the manufacturing technique that welding, especially on thin-walled plastic pipes, must be carried out very carefully so as not to damage the pipe wall to which the welding seam must be laid. if the weld was carried out too carefully, there would be no guarantee that the weld seam was tight enough under the loads that it has to withstand, if the weld seam is not tight enough, the sealing function is impaired. The known cable conductor bundles and even the tube assemblies of which they are assembled are manufactured without special measures according to the rules for extrusion of thermoplastic plastics and pipe aggregates.

Opis rešitve tehničnega problema in izvedbenih primerov s seznamom slikDescription of the solution of the technical problem and examples with a list of pictures

Izum je zasnovan na cilju, da se predvidi snop kabelskega vodnika zgoraj opisane konstrukcije in z zgoraj določenim namenom, ki se lahko izdela na enostaven način in na katerem varilni šiv je in ostane dovolj tesen pod kakršnimikoli normalnimi bremeni. Izum prav tako sloni na cilju, da se predvidi postopek, ki omogoča proizvodnjo takšnega vodniškega snopa na izrazito enostaven nači n.The invention is based on the object of providing a bundle of cable conductors of the structure described above and with the purpose specified above, which can be made in a simple manner and in which the weld seam is and remains tight enough under any normal loads. The invention is also based on the object of providing a process that enables the production of such a guide bundle in a particularly simple manner.

Zato, da se doseže svrha glede na snop kabelskega vodnika, uči izum, da sta obe tesnilni rebri vodniškega snopa v snopu kabelskega vodnika drug nasproti drugega ter sta zvarjena skupaj z vzdolžno raztezajočim se varilnim šivom, pri čemer so integralne tvorne črte tesnilnih reber vodniškega snopa v snopu kabelskega vodnika primerno druga proti drugi. Po prednostni izvedbi je sestava narejena tako, da so spojne stojine integralno oblikovane na zunanjih ceveh vzdolž spojnih črt, ki diametrialno stoje nasproti tesnilnih reber vodniškega snopa. Vzdolžno iztezajoči se zvarni šiv je prednostno nepretrgan zvarni šiv, toda ima lahkoIn order to achieve purpose with respect to the cable guide bundle, it teaches the invention that the two guide blades are in the bundle opposite each other and are welded together with a longitudinally extending welding seam, the integral forming lines of the guide binder ribs in the cable guide bundle against each other. According to a preferred embodiment, the assembly is made in such a way that the joints are integrally formed on the outer tubes along the connecting lines, which diametrically stand opposite the sealing ribs of the guide bundle. The longitudinally extending weld is preferably a continuous weld, but may have

I prekinitve, po možnosti tako nameščene, da nameravana nepredii— nost ni prizadeta.I interruptions, preferably located so that the intended continuity is not affected.

Tzum izvira iz spoznanja, da se lahko izvede popolnoma tesen varilni šiv brez težave na snopu kabelskega vodnika konstruiranem kot opisano zgoraj, če so ta tesnilna rebra vodniškega snopa kot opisano privarjena drug na drugega, tj. da niso privarjena na zunanjo steno priključene cevi iz umetne snovi. To neposredno varenje tesnilnih reber vodniškega snopa, ki stoje drug nasproti drugega, drugo z drugim se lahko izvede brez kakršnihkoli težav in ne da bi poškodovali cevi iz umetnih snovi z uporabo običajnega in preizkušenega postopka za varenje termoplastičnih umetnih snovi kakor so nadzvočno varenje, lasersko varenje ali slično. Kot posebno zanesljiva izvedba snopa kabelskega vodnika po izumu, ki prenese kakršnekoli nastopajoče obremenitve, je označena s tem, da se izvede vzdolžno se iztezajoči varilni šiv na tesnilnih rebrih vodniškega snopa kot kontaktni var z navzgor zapognjenimi, robnimi površinami tesnilnih reber vodniškega snopa, ki so obrnjena drug proti drugemu, če vzamemo v poštev, da mora varilni šiv prevzeti določena bremena bodisi, da se navija snop kabelskega vodnika po izumu na kabelski boben ali da ga položimo ali potem ko je bil položen, uči izum, da so cevi iz umetne snovi v središču snopa kabelskega vodnika sestavljene iz integralno oblikovanih elementov jedra in/ali integralno oblikovanih elementov in stabiliziranih z imenovanimi elementi jedra kakor tudi iz varjenih tesnilnih reber vodniškega snopa. Kljub takšni stabilizaciji se lahko zagotovi brez težav, da ostane snop kabelskega vodnika dovolj fleksibilen, da se navije na ali da se odvija s kabelskega bobna, ali da se položi, ali potem ko je bil položen pod zemljo v področjih s posedanjem tal. Izum tudi uči, da je zaključena zračnost, določena in omejena s širino varjenih tesnilnih reber vodniškega snopa med cevmi iz umetne snovi in/ali )Tzum stems from the realization that a completely tight welding seam can be made without difficulty on a cable conductor bundle constructed as described above if these conductor bundle seals are welded to each other as described, i.e. that plastic pipes are not welded to the outer wall. This direct welding of the conductor sealing ribs facing each other can be effected without any problems and without damaging the plastic tubes by using a conventional and proven procedure for welding thermoplastic plastics such as supersonic welding, laser welding but similar. As a particularly reliable embodiment of the cable guide bundle according to the invention, which can withstand any occurring loads, it is characterized by the longitudinally extending welding seam on the guide rib sealing ribs as a contact weld with the upwardly bent, edge surfaces of the guide rib seals. facing each other, bearing in mind that the weld seam must assume certain loads, either to bundle the cable guide of the invention onto the cable drum or to lay it, or after it has been laid, teaches the invention that plastic pipes at the center of the cable guide bundle, consisting of integrally formed core members and / or integrally formed members and stabilized with said core members as well as welded guide rib seals. Despite such stabilization, it can be easily ensured that the cable guide bundle remains flexible enough to be wound on or off the cable drum, or to be laid, or after it has been laid underground in areas with soil seating. The invention also teaches that the closed air gap is defined and limited by the width of the welded sealing ribs of the guide bundle between plastic pipes and / or)

elementi jedra' in/ali kantaktnimi elementi snopa kabelskega vodnika. Ta izvedba po izumu je zlasti pomembna, če ima snop kabelskega vodnika jedrne elemente in/ali kontaktne elemente kot opisano.core elements' and / or cantilever cable harness elements. This embodiment of the invention is particularly important if the cable guide bundle has core elements and / or contact elements as described.

Vedno je možnost, da se poveže v snop množica ravnih cevnih agregatov, od katerih vsebuje vsak več cevi iz umetne snovi v en sam snop kabelskega vodnika, ki ima večje število cevi iz umetne snovi kot v primerjavi s posameznimi cevnimi agregati. Da to dosežemo, se lahko privari skupaj vsaj ena stojina, ki povezuje cevi iz umetne snovi, dveh tesnilnih reber vodniškega snopa s prekritim šivom1v snopu kabelskega vodnika.It is always possible to bundle a plurality of flat tube assemblies, each of which contains more plastic tubes into a single bundle of cable leads, which has a larger number of plastic tubes than in comparison to individual tube aggregates. To achieve this, at least one web connecting two plastic conduit sealing ribs with a covered seam 1 in the cable guide bundle may be welded together.

Druga izvedba snopa kabelskega vodnika izuma, ki se odlikuje po varilnem šivu, odpornem na visoke mehanske obremenitve, je označena s tem, da imajo tesnilna rebra vodniškega snopa varilni šiv, izveden kot varilni greben, ki se tvori tako, da se plosko zavarita skupaj dva delno v greben oblikovana varilna profila s predi zdelanimi varilnimi lici, integralno oblikovanimi na robovih tesnilnih reber vodniškega snopa. Na ta način se lahko namesti varilni nanos na vloženi način med varilnimi profili, zavarjenimi v varilni greben. Po prednostni izvedbi izuma je nameščen vložen varilni nanos v varilnem žlebu, ki je oblikovan integralno na varilnem profilu.Another embodiment of the bundle of the cable guide of the invention, characterized by a welding seam resistant to high mechanical stress, characterized in that the sealing ribs of the guide bundle have a welding seam formed as a welding ridge formed by welding together two partly welded shaped welding profiles with pre-welded welding faces integrally formed at the edges of the guide bundle sealing ribs. This way the welding application can be installed in the filed between welding profiles welded into the welding ridge. According to a preferred embodiment of the invention, an embedded welding layer is installed in a welding groove that is formed integrally on the welding profile.

Snop kabelskega vodnika po izumu se lahko izdela na različne načine. Posebej se lahko izdela raven cevni agregat in ravni cevni agregati se lahko povežejo v snop kabelskega vodnika že med proizvodnim postopkom cevnega agregata ali pozneje v povezavi s polaganjem snopa kabelskega vodnika. Predmet izuma je tudi proizvodni postopek snopa kabelskega vodnika po izumu, ki se lahko integrira, ne da bi podvzeli druge ukrepe, v obstoječo produkcijsko linijo za ravne cevne agregate. Po tej metodi se lahko raven cevni agregat, obstoječ iz cevi iz umetne snovi, povezovalnih stojin in s tesnilnimi elementi cevnega snopa, ekstrudira s pomočjo polžastega ekstruderja za umetne snovi v proizvodni liniji. Po ekstrudi ranju se raven cevni agregat kontinuarno sestavlja v snop kabelskega vodnika glede na hitrost ekstrudiranja v proizvodni liniji, in tesnilna rebra vodniškega snopa se takoj nato kontinuarno vare glede na hitrost ekstrudiranja. Kot opisano je predvidena zračnost za navijanje snopa na kabelski boben med tem postopkom. Glede na prednostno izvedbo izuma, so nameščena tesnilna rebra vodniškega snopa lice proti licu med postopkom spajapja cevnih agregatov, s čemer ali potem ko se tvori kontaktni varilni šiv. Razume se, da se lahko po namenuThe cable guide bundle according to the invention can be manufactured in various ways. Particularly straight tube assembly can be made and straight tube assemblies can be connected into the cable guide bundle during the pipe assembly manufacturing process or later in connection with the cable guide bundle assembly. The subject of the invention is also the manufacturing process of the cable guide bundle according to the invention, which can be integrated without taking other measures into the existing production line for straight pipe aggregates. According to this method, a straight tube assembly existing from a plastic pipe, connecting racks and pipe sealing elements can be extruded using a screw plastic extruder in the production line. After extrusion, the straight tubular assembly is continuously assembled into the cable guide bundle according to the extrusion rate in the production line, and the guide bundle sealing ribs are then continuously welded according to the extrusion rate. As described, the play is provided for winding the bundle on the cable drum during this operation. According to a preferred embodiment of the invention, sealing ribs of the guide bundle are placed face-to-face during the coupling process of the tubular aggregates, with or after the contact welding seam is formed. It is understood that by purpose

I izuma raven cevni agregat tudi kalibrira po ekstrudiranju ravnega cevnega agregata. Ravni cevni agregat se lahko poveže v snop kabelskega vodnika po ekstrudiranju s pomočjo pomožne naprave. Da se olajša varilni postopek, priporoča izum, da se ekstrudira ravni cevni agregat s tesnilnimi rebri vodniškega snopa, ki imajo vzdolžno raztezajoče se obravnavane robne grebene in da se loči meje tesnilnih reber vodniškega snopa z obdelavo robnih grebenov, ki strle iz varilnih šivov, z varjenjem skupaj tesnilnih reber vodniškega snopa.The invention also calibrates the straight pipe assembly after extruding the straight pipe assembly. The straight tubular assembly can be connected to the cable guide bundle after extrusion using an auxiliary device. In order to facilitate the welding process, the invention recommends extruding a straight pipe assembly with guide bundle sealing ribs having longitudinally extending edge ridges and separating the boundaries of the guide bundle sealing ribs by treating the edge ridges projecting from welding seams with welding together the guide rib sealing ribs.

I če je opremljen snop kabelskega vodnika, ki se mora proizvesti, z integralno oblikovanimi varilnimi profili, uči izum proizvodni postopek, pri katerem se raven cevni agregat ekstrudira s tesnilnimi rebri vodniškega snopa, ki Ima na svojih robovih vzdolžno se iztezajoče, delno v greben oblikovane varilne profile s predoblikovanimi varilnimi lici, pri čemer so varilni profili kontinuarno varjeni glede na hitrost ekstrudiranja. Na ta način je možno, da se namesti dodatni varilni nanos med varilnimi lici med varjenjem varilnih profilov.I If the bundle of the cable conductor to be fabricated is provided with integrally formed welding profiles, the invention teaches a manufacturing process in which a straight tube assembly is extruded with sealing ribs of a bundle having at its edges extending longitudinally, partly into a ridge formed welding profiles with preformed welding faces, the welding profiles being continuously welded according to the extrusion rate. In this way, it is possible to install additional welding coating between welding faces during welding of welding profiles.
