Description
Descrizione di un brevetto d'invenzione a nome: Description of an invention patent in the name:
Il presente trovato si riferisce a un morsa di amarro a compressione per condizioni estreme. The present invention relates to a compressed amar vice for extreme conditions.
Attualmente per vincolare le corde di linee elettriche ai tralicci dell'alta tensione, in corrispondenza di una porzione terminale delle corde, sono previste dei particolari dispositivi denominati morse di ammarro. Currently, in order to tie the cords of electric lines to the high voltage pylons, in correspondence with an end portion of the cords, particular devices called mooring clamps are provided.
Tali dispositivi presentano un elemento internamente cavo in cui viene inserito il tratto terminale della corda. These devices have an internally hollow element into which the terminal portion of the rope is inserted.
L'elemento internamente cavo viene plasticamente deformato per comprimere la corda al suo interno mantenendola bloccata. The internally hollow element is plastically deformed to compress the rope inside, keeping it locked.
Le morse tradizionali riescono a trattenere le corde tradizionali con nuclei in acciaio senza grossi problemi. Traditional vices are able to hold traditional ropes with steel cores without major problems.
Le corde con nuclei realizzati in materiali compositi presentano una resistenza a trazione molto maggiore di quelle tradizionali e pertanto potrebbero potenzialmente essere realizzate delle campate più lunghe. Tuttavia, sebbene le nuove corde possano reggere carichi più elevati, le morse tradizionali non possono trattenere la corda perché il nucleo in fibre di carbonio/vetro ha una resistenza limitata alla compressione trasversale, e sopra certi carichi e pertanto la corda si sfila dalla morsa. Ropes with cores made of composite materials have a much higher tensile strength than traditional ones and therefore could potentially be made of longer spans. However, although the new ropes can handle higher loads, traditional vises cannot hold the rope because the carbon fiber / glass core has limited resistance to transverse compression, and over certain loads and therefore the rope slips out of the vise.
Scopo della presente invenzione è quello di fornire una morsa di ammarro che superi gli inconvenienti tecnici della tecnica nota e che quindi sia in grado di mantenere fissa la corda anche se soggetta a carichi di trazione molto maggiori rispetto a quelli a cui possono essere assoggettate le corde con nucleo in acciaio. The purpose of the present invention is to provide a mooring vise that overcomes the technical drawbacks of the known art and is therefore capable of keeping the rope fixed even if subjected to much greater tensile loads than those to which the ropes can be subjected. with steel core.
Questi ed altri scopi vengono raggiunti realizzando una morsa secondo gli insegnamenti tecnici delle annesse rivendicazioni. These and other purposes are achieved by making a vice according to the technical teachings of the attached claims.
Ulteriori caratteristiche e vantaggi del trovato risulteranno evidenti dalla descrizione di una forma di realizzazione preferita ma non esclusiva del trovato illustrata titolo esemplificativo e quindi non limitativo nei disegni allegati, in cui: Further characteristics and advantages of the invention will become evident from the description of a preferred but not exclusive embodiment of the invention illustrated by way of example and therefore not limitative in the attached drawings, in which:

la figura 4 è una sezione presa lungo la linea 4-4 di figura 5; Figure 4 is a section taken along the line 4-4 of Figure 5;

la figura 6 mostra una vista dall'alto di figura 1, di un particolare della morsa. Figure 6 shows a top view of Figure 1 of a detail of the vice.
Con riferimento alle figure citate, viene mostrato una morsa di amarro indicata complessivamente con il riferimento numero 1. With reference to the aforementioned figures, a starter vice is shown, indicated as a whole with the reference number 1.
Essa comprende un embolo 2 presentante una porzione internamente cava 2C da cui si diparte una porzione intermedia 2A che termina con un anello 2B che funge da elemento di fissaggio della morsa 1 e della corda 4 da essa trattenuta a un traliccio dell'alta tensione. It comprises an embolus 2 having an internally hollow portion 2C from which an intermediate portion 2A departs which ends with a ring 2B which acts as an element for fastening the vice 1 and the rope 4 retained by it to a high voltage pylon.
La corda 4 presenta un nucleo 5 preferibilmente realizzato da cavi portanti cordati realizzati in materiale composito con fibre di vetro e carbonio in una matrice di resina termoplastica. Il nucleo 5 è rivestiti da una guaina in alluminio. Attorno al nucleo 5 previsti uno o due anelli di conci 6 in alluminio elettroconduttivi . The rope 4 has a core 5 preferably made of stranded carrying cables made of composite material with glass and carbon fibers in a thermoplastic resin matrix. The core 5 is covered with an aluminum sheath. Around the core 5 one or two rings of electroconductive aluminum segments 6 are provided.
In una parte terminale della corda 4 i cavi portanti cordati che costituiscono il nucleo 5 sono scoperti dalla guaina in alluminio e dai conci elettroconduttivi. Tale parte terminale è inserita nella porzione cava dell'embolo. In a terminal part of the rope 4 the stranded carrying cables which constitute the core 5 are exposed by the aluminum sheath and by the electroconductive segments. This terminal part is inserted in the hollow portion of the embolus.
Vantaggiosamente le pareti che definiscono la porzione cava dell'embolo presentano delle scanalature a lobi che presentano lo stesso passo di cordatura dei cavi del nucleo. In sostanza l'embolo è "avvitato" sui cavi che formano il nucleo e la parte esterna dei cavi viene ad alloggiarsi proprio nelle scanalature. Advantageously, the walls which define the hollow portion of the thrombus have lobed grooves which have the same stranding pitch as the cables of the core. In essence, the thrombus is "screwed" on the cables that form the core and the external part of the cables is housed in the grooves.
In una forma preferita di realizzazione le scanalature, invece di presentare il passo del nucleo, sono sostanzialmente rettilinee. Esse sono sostanzialmente dei fori eccentrici, in numero pari al numero dei cavi portanti, che presentano asse parallelo a quello dell'embolo. In a preferred embodiment, the grooves, instead of having the pitch of the core, are substantially straight. They are substantially eccentric holes, equal in number to the number of supporting cables, which have an axis parallel to that of the thrombus.
In sostanza tali fori hanno il proprio asse su una circonferenza con centro sull'asse dell'embolo. Basically these holes have their own axis on a circumference centered on the axis of the thrombus.
L'accoppiamento dell'embolo sui cavi della corda provoca lo svolgimento e gli stessi, nella porzione interna al nucleo, risultano privi di cordatura. The coupling of the thrombus on the cables of the rope causes the unwinding and the same, in the internal portion of the core, are without strings.
Inoltre secondo la presente invenzione prima di deformare plasticamente la porzione cava dell'embolo contro il nucleo, attorno a quest'ultimo viene disposto del collante 8, preferibilmente epossidico che garantisce una perfetta adesione e tenuta della corda sull'embolo, permettendo alla morsa di reggere carichi molto più alti rispetto alle corde tradizionali. Furthermore, according to the present invention, before plastically deforming the hollow portion of the thrombus against the nucleus, the adhesive 8 is placed around the latter, preferably epoxy, which guarantees perfect adhesion and sealing of the cord on the thrombus, allowing the vice to hold much higher loads than traditional ropes.
La tenuta della corda sull'embolo è ancora migliorata dalla filettatura di quest'ultimo, con lo stesso passo di cordatura dei cavi del nucleo. The tightness of the string on the embolus is further improved by the threading of the latter, with the same stranding pitch as the core cables.
Sul nucleo 5, fra l'embolo e i conci 6 è calzato un elemento anulare 9 elettroconduttivo che presenta esternamente sostanzialmente lo stesso diametro esterno della corda in una porzione in cui sono presenti anche i conci elettroconduttivi. On the core 5, between the embolus and the segments 6, an annular electroconductive element 9 is fitted which externally has substantially the same external diameter as the cord in a portion in which the electroconductive segments are also present.
La morsa comprende inoltre un manicotto 10 almeno parzialmente calzato su detto embolo, su detto elemento anulare e su almeno parte di detti conci. Il manicotto 10 è deformato plasticamente sulla porzione intermedia 2A dell'embolo. Vantaggiosamente la superficie della porzione 2A presenta creste che migliorano l'interconnessione tra la porzione 10A deformata del manicotto e 1'embolo . The vice also comprises a sleeve 10 at least partially fitted on said embolus, on said annular element and on at least part of said segments. The sleeve 10 is plastically deformed on the intermediate portion 2A of the thrombus. Advantageously, the surface of the portion 2A has ridges which improve the interconnection between the deformed portion 10A of the sleeve and the thrombus.
Vantaggiosamente il manicotto 10 presenta un diametro interno sostanzialmente corrispondente a quello esterno dell'elemento anulare 9. L'elemento anulare permette una perfetta connessione elettrica tra i conci elettroconduttivi della corda e il manicotto 10, che presenta ad esso saldata, una patella 11 conduttiva a cui è possibile fissare una derivazione 12 di un cavo elettroconduttivo 18. La derivazione è fissata alla patella 12 tramite bulloni 13. Advantageously, the sleeve 10 has an internal diameter substantially corresponding to the external one of the annular element 9. The annular element allows a perfect electrical connection between the electroconductive segments of the rope and the sleeve 10, which has a conductive flap 11 welded to it. to which it is possible to fix a branch 12 of an electroconductive cable 18. The branch is fixed to the patella 12 by means of bolts 13.
Vantaggiosamente fra l'elemento anulare e il nucleo, e fra l'elemento anulare 9 e il manicotto 10 è disposta della pasta antiossidante. Advantageously, antioxidant paste is arranged between the annular element and the core, and between the annular element 9 and the sleeve 10.
