Uppfinnare: T F Peterson Foreliggande uppfinning hanfi5r sig till en anordning for samverkan med tradar, kablar, tvinnade kroppar och liknande, innefattande ett flertal i forvag spirallormade forstarkningselem,ent med samma oppna stigning och stigningsriktning samt med ringa langd i forhalland.e till den kropp, vilken dc skola anbringas vid °eh avlagsnas fran pa platsen, varvid de aro anordnade att manuellt kunna anbringas kring kroppen Wined dess langdriktning till bildande av ett hylsliknande 101- je med begransad langd. Forutom som en armering kunna sadana anordningar tjana som ftiste for olika redskap, sasom vibrationsdarnpare, till undvikande av for linan skadliga koncentrationer av friktions- cich tryckkrafter, liksom Oxen vibrationspakanningar. Inventor: TF Peterson The present invention relates to a device for cooperating with wires, cables, twisted bodies and the like, comprising a plurality of predominantly helical reinforcing elements, one with the same open pitch and pitch direction and with a small length in relation to the body which dc should be applied at ° eh are removed from the site, whereby they are arranged to be able to be manually applied around the body Wined its longitudinal direction to form a sleeve-like 101- je of limited length. In addition to being a reinforcement, such devices can serve as fasteners for various tools, such as vibration dampers, to avoid harmful concentrations of frictional and compressive forces on the line, as well as Taurus vibration packers.

Som regel aro spiralelementen utformade med en innerdiameter, som Or lika med eller mindre On ytterdiametern av ifthgavarande linor eller den tvinnade kropp, kring vilken de anbringas fill astadkonimande av en omgripande kraft, som laser armeringselement och kropp vid varandra till forhindrande -av inbordes axiell forskjutning. As a rule, the spiral elements are formed with an inner diameter equal to or less than the outer diameter of the respective ropes or the twisted body, around which they are applied to provide a gripping force, as laser reinforcing elements and body together to prevent inboard axial displacement. .

Tidigare bar for anbringande ph en tvinnad kropp en typ av armeringselement any-ants, vilka ha haft vidgade mittpartier till bildande av ett hylsliknande och av ett fritt utrymme frail den tvinnade kroppen skill holjesparti for fastsattning av klammor, vilka till foljd av det fria spelrummet forhindras overfora tryekkrafter till den tvinnade kroppen. Vid delta arrangem.ang Or emellertid avsikten den, att satsen ■armeringselement vid ,sina andp.artier ph &me sidor om det vidgade mittpartiet shall ha normal diameter, dvs. en inre spiral-diameter lika med eller nagot mindre an den tvinnade kroppens ytterdiameter, for att kroppen fast skall omgrip.as°eh elementens frau kroppens yta med spel skilda hilljesparti shall hallas i ett fixerat lage rel.ativt kroppen. Previously, for application to a twisted body, it had a type of reinforcing element any-ants, which had widened middle portions to form a sleeve-like and of a free space between the twisted body separating the housing portion for attaching staples, which are prevented due to the free play transmitting compressive forces to the twisted body. In the case of delta arrangement, however, the intention is that the set of ■ reinforcing elements at, their andp.artier ph & me sides of the widened middle portion shall have a normal diameter, i.e. an inner spiral diameter equal to or slightly smaller than the outer diameter of the twisted body, in order for the body to be firmly gripped.as the elements of the elements from the body with play-separated shelf portions shall be held in a fixed layer relative to the body.

I motsats hartill kanneteeknas anordningen enligt uppfinningen darav, att holjets inner diameter Or st8rre an den av holjet omslutna kroppens diameter, och den mellan holjets insida och kroppens utsida bildade ringspalten atminstone utmed en del av sin axiella langd Or fylld med avstandshhIlande material, varjamte en klamanordning finnes for att fast orngripa forstarknings,elementens utsidor. In contrast, the device according to the invention is characterized in that the inner diameter of the casing is larger than the diameter of the body enclosed by the casing, and the annular gap formed between the inside of the casing and the outside of the body at least along part of its axial length is filled with spacer material. is available to firmly grip the outside of the reinforcement elements.

Genom uppfinningen mojliggores fastning av klammor for upphangning av ledare eller for anbringande av vibrationsdampare, sh. att spiralelementen upptaga klamkraf ten i stallet for den tvinnade kroppen. Likash medfor atrangemanget en effektiv dampning av vibrationerna_ i frihOngande linor. The invention makes it possible to fasten clamps for suspending conductors or for mounting vibrating dampers, sh. that the spiral elements absorb the clamping force in the place of the twisted body. Likash entails an efficient damping of the vibrations_ in free-hanging ropes.

The invention is described in more detail with reference to the accompanying drawing, in which Fig. 1 shows in perspective a partial view of a twisted body, in which a plurality of reinforcing elements arranged according to the invention arranged in helical shape are arranged, as in their spirits supported by eccentric weights provided with vibration evaporators, Fig. 2 is a longitudinal sectional view of the device shown in Fig. 1, showing how the reinforcing elements rest snot a lure, annular and plastic pressure element for fixing the tubular reinforcement to the twisted body, Fig. 3 analogous to Fig. 2 view, the ash-like insertion of a long, stretched, rubber-like tube between the reinforcement and the body, Fig. 4 a further embodiment of the invention with two. sets of helically shaped reinforcing elements of different diameters together with a plastic tube, Fig. 5 a partial scale in stone scale of a plastic or rubber coated reinforcing element, Fig. 6 a sicto view of a further embodiment of the invention, in which pa a-vs-Land Iran mutually placed plastic filling elements are arranged between the reinforcing tube and it. twisted body Small formation of axial thrust bearings cooperates with a suspension clamp arranged between them, Fig. 7 a longitudinal sectional view of device- Dupl. at Fig. 21 c: 6 show the modifications of the species arrangements shown in Figs. 4 and 7, and Figs. 10, 11 and 12 a longitudinal sectional view, a partial view and a cross-sectional view on a stone scale.

De i forvag spiralforrnade forstarkningselementen dro utforda .av runda eller profilerade tsadar med tilltheklig styrka och styvhet f8r att fasthalla en tvinnad kropp, sasom en elektrisk overforingslinje, -vid dess fdstorgan utan att medfora koncentrerade 10jningspakanningar samt ha vissa vibrationsdampande egenskaper till foljd ,av den tvinnade konstruktionens karaktar. De aro utformade med tillrackligt stor stigning for .att kunna ambringas vid de tvinnade kropparna fra'n sidan, utan aft harvid elasticirbetsgra.nsen hos tradmaterialet overskrid.es, och utan att nagon fri ande hos den tvinnade kroppen behover vara tillganglig for inforing. The predominantly helically reinforced reinforcing elements were challenged by round or profiled tsads with sufficient strength and rigidity to hold a twisted body, such as an electrical transmission line, at its fasteners without entailing concentrated tensile gaskets and having certain vibration-damping properties. the nature of the construction. They are designed with a sufficiently large pitch to be able to be applied to the twisted bodies from the side, without exceeding the elastic working limit of the thread material, and without any free spirit of the twisted body having to be accessible for insertion.

Ehuru i denna beskrivning uttrycket "tvinnad kropp" anvants sasom den term, som oftast tacker genomsnittskonstruktionerna, skall det observeras, att uppfinningens tilllampning ingalunda är begransad till sadana kroppar utan likaval kan tillampas pa en slat lina eller pa vilken som heist typ av mantlade ledningar, sasom exempelvis en plastmantlad telefonkabel. Av detta skal skola alla hanvisningar till den "tvinnade kroppen C" i beskrivning och patentansprak tolkas i den liar anforda vidare bemarkelsen. Although in this description the term "twisted body" is used as the term which most often refers to the average constructions, it should be noted that the application of the invention is by no means limited to such bodies but can equally be applied to a smooth line or to any type of sheathed wire. such as a plastic sheathed telephone cable. Of this, all references to the "twisted body C" in the description and patent claims are to be construed as referring further to the disclosure.

I fig. 1 och. 2 aro ett flertal i forvag skruvspiralformade forstarkningselement A anbragta kring den tvinnade kroppen C till bildande av ett kroppen omgivande ror med nagot stOrre innerdiameter an den tvinnade kroppens ytterdiameter. In Fig. 1 and. 2, a plurality of helically helical reinforcing elements A are arranged around the twisted body C to form a tube surrounding the body with a slightly larger inner diameter than the outer diameter of the twisted body.

I det mellan den tvinnade kroppen C och fOrstarkningsroret A bildade ringformade utrymmet är en elastisk, gummiliknande fyllnadskropp B, i det foljande kallad "pl.astiskt roe eller "plastiskt element", infOrd, som kan vara tu.delad for aft mojliggora latt mon-tering, eller vara spire.lformigt virad runt den tvinnade kroppen mellan denna och de spiral-f ormade fiirstarkningselementen. Forstarkningselementen pressa del plastiska elementet till anliggning mot den tvinnade kroppen, varfgenom de hada enheterna stadigt fixeras vid varandra. Vid denna utforingsform kunna forstarkningselementens andar fritt rora sig i radiell och periferiell riktning i forhallande till den tvinnade ledaren, sâ att en effekti-v Vibrationsdampning erhalles. In the annular space formed between the twisted body C and the reinforcing tube A, an elastic, rubber-like filling body B, hereinafter referred to as a "plastic tube or" plastic element ", is inserted, which may be divided to allow easy mounting. or be helically wound around the twisted body between it and the helical reinforcing elements. The reinforcing elements press the plastic element into abutment against the twisted body, whereby the hot units are firmly fixed to each other. In this embodiment, the spirits of the reinforcing elements can freely move in a radial and peripheral direction in relation to the twisted conductor, so that an effective vibration damping is obtained.

For forstarkning av derma senare dampningsverkan aro enligt fig. 1 och 2 med excentriskt anordnade vikter forsedda klanunor D av i och for sig kand typ anbragta vid vissa partier hos forstarkningsroret A, varigenorn dettas initialvridmoment Ras och armed dampningsverkan gentemot vibrationer hOjes. Lampliga klamorgan kunna vara anbragta vid riirets mittparti, i -vilket fall forstarkningselementen A och den elastiska fyllnads kroppen B absorhera klainkraftern.a, sâ att ej nagon skada pa den tvinnade kroppen C uppstar. To amplify this later vaporizing action, according to Figs. 1 and 2, eccentrically arranged weights are provided with clans D of the per se type arranged at certain portions of the reinforcing tube A, whereby its initial torque Ras and armed vaporizing action against vibrations are increased. Lampable clamping means may be provided at the central portion of the tube, in which case the reinforcing elements A and the elastic filling body B absorb the clamping forces, so that no damage to the twisted body C occurs.

I fig. 3 visas en annan utforingsform, vid vilken forst det plastiska elementet B Or an-brag kring en tvinnad kropp eller ledare C. Tva eller flera i fOrvag spiralformade forstarkningselement A aro darefter anbragta kring .det plastiska elementet och darefter klammor D, antingen for upphangning vid en mellanliggande punkt pa anordningen eller f8r fastsattning av vibrationsdampare. I detta fall .absorbera forstarkningsroret A och det plastiska elementet B, vilket utfyller hela spa-let mellan den tvinnade kroppen och f Orstarkningselementen, de tryckkrafter, som upptrada vid klammornas anbringande. Fig. 3 shows another embodiment, in which first the plastic element B is mounted around a twisted body or conductor C. Two or more helically helical reinforcing elements A are then arranged around the plastic element and then clamps D, either for hanging at an intermediate point on the device or for attaching vibration dampers. In this case, absorb the reinforcing tube A and the plastic element B, which fills the entire space between the twisted body and the reinforcing elements, the compressive forces which occurred during the application of the clamps.

I fig. 4 Or den tvinnade kroppen C forst forsedd med ett flertal spiralformade element A', vilka Oro utforda med en innerdiameter, som ,ar lika med eller mindre an den tvinnade kroppens C, och vilka i ena anden ansluta till ett den tvinnade kroppen likasa omslutande plastiskt rOr B med vasentligen samina ytterdiameter Sum elementen A'. Darefter Or en andra sats spiralelement A med en inner-diameter, som Or lika med eller mindre On ytterdiarnetern has de forst pamonterade spiralelementen A' och det plastiska roret B, anbragt Over dessa till bildande av ett koncentriskt lager armeringselement, vilka befinna sig ph avstand frau kroppen C samt tjana som faste for klamanordningar D, sasom vibrationsdampare av den i fig. 1 visade typen. In Fig. 4, the twisted body C is first provided with a plurality of helical elements A ', which Oro challenge with an inner diameter which is equal to or less than the twisted body C, and which in one spirit connect to a twisted body. like enclosing plastic tube B with essentially the same outer diameter Sum elements A '. Then Or a second set of spiral elements A with an inner diameter equal to or less On the outer diarnet has the first mounted spiral elements A 'and the plastic tube B, arranged Above these to form a concentric layer of reinforcing elements, which are ph spaced apart. frau body C and serve as fasteners for clamping devices D, such as vibration dampers of the type shown in Fig. 1.

I fig. 6 och 7 visas ytterligare en tillanapning ,av denna princip, i det att den tvinnade kroppen C Or omgiven av tvenne, pa avsand Iran varandra placerade plastiska element B, utanpa vilka ett ror av i forvag spiralformade forstarkningselement Or anbragt. Ehuru f Orstarkningselementen vid denna utforingsform ha storre innerdiameter an den tvinnade kroppens ytterdiameter, Or deras innerdiameter nagot mindre On ytterdiametern has de plastiska elementen B, vilka vidga forstarkningselementen till bildande av -Iva. pa avstand fran varandra belagna ansvallningar utmed kroppens C .axel. Figures 6 and 7 show a further adaptation, of this principle, in that the twisted body C Or is surrounded by two plastic elements B placed one on top of the other, on which a tube of helically helical reinforcing elements Or is arranged. Although the reinforcing elements in this embodiment have a larger inner diameter than the outer diameter of the twisted body, their inner diameter is slightly smaller. The outer diameter has the plastic elements B, which widen the reinforcing elements to form -Iva. at a distance from each other covered swellings along the body's C axis.

Sasom framgar av fig. 7 Mlles forstarkningselementens parti mellan ,ansvallningarna pa avstand fran kroppen C, sh att en for Lipphangnings- eller fastandamal anbragt klamma E kan atdragas med sa. star kraft, att nomnda parti mellan ansvallningarna hoptryckes utan att komma i beroring med den tvinnade kroppen, ph samma gang som denna axiellt fixeras till foljd av .ansvallningarnas stod mot klamman E. As can be seen from Fig. 7 Between the part of the reinforcing elements between the swellings at a distance from the body C, it is possible that a clamp E arranged for lip hanging or fastening purposes can be tightened with so. star force, that the said portion between the swellings is compressed without coming into contact with the twisted body, ph at the same time as this is axially fixed as a result of the swellings stood against the clamp E.

I fig. 8 visas en ledare eller annan lina C, som Or forstarkt medelst tva eller flera satser i forvag spiralformade element A', placerade med avsevart mellanrum i axialled och omgrip.ande linan pa gangse satt. De bada satserna A' Oro overbryggade av ytterligare en — —3 sats i forvag spiralformade forstarkningselement A, vilkas innerdiameter fir nagot mindre an elementens A' ytterdiameter, varigenom dessa fast omgripas samt ett slutet utryinme erhalles mellan dam, .dar en klamma kan anbringas. Som ett alternativ kan utrymmet mellan de bade axiellt atskilda satserna armeringselement A' vara utfyllt av ett plastiskt ror B, sasom framgar av fig. 9. I bada fallen neutraliseras vid anordningens mittparti angripande tryckkrafter i utrymmet eller i det plastiska roret utan att .skada ifragavarande ledare eller lina. Fig. 8 shows a conductor or other line C, which is reinforced by means of two or more sets of precast helical elements A ', placed at considerable intervals in the axial direction and surrounding the line at the same time. The two sets A 'Oro are bridged by a further set of helically helical reinforcing elements A, the inner diameter of which is slightly smaller than the outer diameter of the elements A, whereby these are firmly gripped and a closed space is obtained between the dams where a bracket can be fitted. As an alternative, the space between the two axially separated sets of reinforcing elements A 'can be filled by a plastic tube B, as shown in Fig. 9. In both cases, attacking forces in the space or in the plastic tube are neutralized at the middle part of the device without damaging the conductor or rope.

I fig. 5 visas i starre skala en delvy av .ett I forvag skruvspiralformat och med plastoverdrag farsett forstarkningselement. Sadana kunna anvfindas vid arrangemang enligt fig. 10, 11 och 12, dar ledaren eller kroppen C fir omgiven av tva eller her spiralforrnade forstarkningselement med plastoverdrag. Sadana plastoverdrag kunna ersatta den i anslutning till de tidigare utforingsformerna beskrivna avstandsanordningen av plastiska ror for absorbering av de tryckkrafter, som kunna upptrada vid klammornas anbringande. Fig. 5 shows on a larger scale a partial view of a reinforcing helical helical format with a plastic coating. Such can be used in arrangements according to Figs. 10, 11 and 12, where the conductor or body C is surrounded by two or more helically reinforced elements with plastic cover. Such plastic coatings can replace the spacer device of plastic tubes described in connection with the previous embodiments for absorbing the compressive forces which may occur during the application of the clamps.

En faredragen meted for framstallning av de plastoverdragna forstarkningselementen är att upphetta •de i forvag skruvspiralformade elementen till lamplig temperatur samt darefter nedsanka dam i en vinylhartsforening, exempelvis den i marknaden under varubenamningen "Plastisol" fOrda. En viss kvantitet harts haftar vid det spiralformade eleinentet, som darefter hfirdas vid en temperatur av ea 180°C. Alternativt kan neopren eller naturgummi anvfindas, som kan anbringas eller pavulkaniseras spiralelementen i enlighet med gangse praxis. A dangerous method for manufacturing the plastic-coated reinforcing elements is to heat the previously helically helical elements to a suitable temperature and then immerse the dam in a vinyl resin compound, for example that in the market under the trade name "Plastisol" fOrda. A certain quantity of resin adheres to the helical element, which is then heated at a temperature of about 180 ° C. Alternatively, neoprene or natural rubber can be used, which can be applied or pavulanized the spiral elements in accordance with current practice.

Det fir icke nodvandigt att helt slutna ror framstallas av forstarkningseleinent for att den foreliggande uppfinningen skall kunna praktiseras. Snarare är mindre an en helt tackande sats element .att foredraga, sfirskilt vid de utforingsformer, dar plastrorsinsatser anvandas. I det .senare fallet behaver endast ett tillrackligt antal, jamnt fordelade eller i tvarsektion symmetriskt anbragla spiralelement anvandas vid anordningen far ,att nodig styrka och styvhet skola sakerstallas ,samt for att erforderlig angreppsyta for klammor skall er- Vidare kunna forstarkningselementen vara lika langa ,eller olika langa, i vilket se-mare fall vissa av elementen karma stracka sig fram till olika punkter utmed ifragakommande ledares eller kropps axel till bildande av en mjuk avslutning av forstarkningsverkan. It is not necessary for completely closed tubes to be made of reinforcing elements in order for the present invention to be practiced. Rather, it is less than a completely thankful set of elements .to prefer, especially in the embodiments where plastror inserts are used. In the latter case, only a sufficient number of evenly distributed or symmetrically arranged spirally arranged spiral elements need be used in the device, so that the necessary strength and rigidity must be provided, and in order for the required attack surface for staples to be equally long, or different lengths, in which case some of the elements karma extend to different points along the axis of the conductor or body to form a soft end of the reinforcing effect.
