Description

Foreliggende oppfinnelse vedrørere en trekk- og opphengningsanordning for hengekabel, bæreline eller lignende omfattende dels et av to deler sammensatt, åpningsbart og hovedsakelig sylindrisk trekk og bærelegeme og dels et kabelomgripende låselegeme. The present invention relates to a pulling and hanging device for a hanging cable, carrying line or the like comprising one part composed of two parts, an openable and mainly cylindrical pull and support body and part a cable-encompassing locking body.

Formålet med oppfinnelsen er å tilveiebringe en anordning The purpose of the invention is to provide a device

som kan benyttes såvel for uttrekning av f.eks. hengekabel som for opphengning av en således uttrukket kabel. Ved hjelp av en slik anordning eliminerer men i mange tilfeller behovet for spesielle trekkorgan, slik som tauvogn eller lignende samt forenkler arbeidet med uttrekning av kabel. Formålet med oppfinnelsen oppnås ved de trekk som er angitt which can be used both for extracting e.g. suspension cable as for suspending a cable thus pulled out. With the help of such a device, however, in many cases, the need for special pulling means, such as a rope trolley or the like, is eliminated and the work with pulling out the cable is simplified. The purpose of the invention is achieved by the features indicated

i karakteristikken i de vedføyde krav. in the characteristics in the attached requirements.

Oppfinnelsen skal nærmere beskrives i tilslutning til vedlagte tegning, der The invention must be described in more detail in connection with the attached drawing, there

Trekk- og bærelegemet ifølge fig. 1 er sammensatt av to deler The traction and support body according to fig. 1 is composed of two parts

11 og 12 av lettmetall, hvilke ved hjelp av gangjern 13 er dreibart forenet med hverandre i anordningens periferi. Trekk-og bærelegemet 11, 12 kan således åpnes, det er videre hovedsakelig sylindrisk og dets indre har i legemets lukkede stilling f orm av en dobbelt kjegle med sin smaleste del 14 i eller i det minste nær legemets midte, se spesielt fig. 2. 11 and 12 of light metal, which are rotatably connected to each other in the device's periphery by means of a turnbuckle 13. The pulling and carrying body 11, 12 can thus be opened, it is further mainly cylindrical and its interior has, in the body's closed position, the form of a double cone with its narrowest part 14 in or at least near the middle of the body, see especially fig. 2.

De nevnte to delene 11 og 12 er forsynt resp. utformet med samvirkende låseorgan i anordningens periferi på den stort sett diametralt motsatte siden av gangjernet 13. På den på tegningen viste utførelsesform består låseorganene av en knast 15 med gjenget hull på delen 11 og av en knast 16 med frittgående hull for en vingeskrue 17 på delen 12. De to hullene korresponderer med hverandre og i legemets lukkede stilling ligger knasten 16 bestandig an mot knasten 15 ved hjelp av vingeskruen 17. The aforementioned two parts 11 and 12 are provided resp. designed with a cooperating locking device in the periphery of the device on the largely diametrically opposite side of the walking iron 13. In the embodiment shown in the drawing, the locking devices consist of a cam 15 with a threaded hole on the part 11 and a cam 16 with a free-running hole for a wing screw 17 on the part 12. The two holes correspond to each other and in the closed position of the body, the cam 16 is permanently abutted against the cam 15 by means of the wing screw 17.

Knasten 15 er utformet med et frittgående hull 18, hvorved knasten får funksjon som opphengningsorgan for hele anordningen. The cam 15 is designed with a freely moving hole 18, whereby the cam functions as a suspension device for the entire device.

Hver og en av de to delene 11 og 12 er ved gangjernet 13 forsynt med en stoppeknast 10 resp. 19, hvilke stoppeknaster i anordningens stengte stilling ligger et stykke fra hverandre og i anordningens maksimalt åpne stilling ligger an mot hverandre med sine anleggsflater 100 resp. 190 og derved hindrer fortsatt åpningsbevegelse hos delene 11 og 12. Each one of the two parts 11 and 12 is provided with a stop cam 10 or 19, which stop cams in the device's closed position lie some distance apart and in the device's maximum open position lie against each other with their contact surfaces 100 or 190 and thereby prevents continued opening movement of parts 11 and 12.

Av fig. 2 fremgår det tydelig at trekk- og bærelegemet From fig. 2 it is clear that the traction and support body

12 innvendig er dobbeltkonisk og har sin smaleste del på mid-ten av legemet. De stiplede linjer, som i fig. 2 antyder kjegleformen, må betraktes kun som et eksempel blant flere mulige utførelsesformer. I en del tilfeller kan det være hen-siktsmessig å ha en mykere (mer avrundet) overgang fra den ene kjeglen til den andre kjeglen. 12 inside is double-conical and has its narrowest part in the middle of the body. The dashed lines, as in fig. 2 suggests the cone shape, must be considered only as an example among several possible embodiments. In some cases, it may be appropriate to have a softer (more rounded) transition from one cone to the other cone.

Fig. 3 viser et i anordningen inngående låselegeme av gummi eller plastisk materiale, hvis ytre har form av en dobbeltkjegle 31, 32 av en slik størrelse at låselegemet passer inn i trekk-og bærelegemets 11, 12 indre. Når låselegemet er innlagt i trekk- og bærelegemet kommer således den ytre kjegleflaten 31 til å ligge an mot den indre kjegleflaten 21 og den ytre kjegleflaten 32 til å ligge an mot den indre kjegleflaten 22. Fig. 3 shows a locking body made of rubber or plastic material included in the device, the exterior of which has the shape of a double cone 31, 32 of such a size that the locking body fits into the interior of the pull and support body 11, 12. When the locking body is inserted into the pull and support body, the outer cone surface 31 thus comes to rest against the inner cone surface 21 and the outer cone surface 32 to rest against the inner cone surface 22.

Videre er låselegemet oppslisset langs en linje 33 med motsatt stigning i forhold til enkelte ledere i kabelen og er i sitt indre utformet med en gjennomgående kanal 40, se fig. 4, med hovedsakelig samme profil som profilen for den hengekabel eller lignende som anordningen er beregnet for. Ifølge fig. 4 har kanalen omtrent kløverbladsform, men kan i andre tilfeller ha Furthermore, the locking body is slit along a line 33 with the opposite pitch in relation to individual conductors in the cable and is internally designed with a continuous channel 40, see fig. 4, with essentially the same profile as the profile for the suspension cable or similar for which the device is intended. According to fig. 4, the channel has an approximately cloverleaf shape, but in other cases can have

f.eks. rund eller kantet form. e.g. round or angular shape.

Anordningen er beregnet på å anvendes på en slik måte at den opphenges i hullet 18 i en stolpe eller lignende, åpnes slik at den kabel eller lignende som skal trekkes ut, kan legges inn i trekk- og bærelegemet 11, 12 (således uten låselegeme på dette stadium), hvorpå delen 12 dreies mot delen 11 til legemet 11, 12 er i sin lukkede stilling, hvorefter låsning skjer i denne stilling ved hjelp av vingeskruen 17. Kabelen kan nu trekkes ut gjennom legemet 11, 12 til sin beregnede stilling. Når dette er oppnådd åpnes legemet 11, 12, kabelen forskyves midlertidig til anlegg utelukkende mot den nu noe nedhengende delen 12, The device is intended to be used in such a way that it is suspended in the hole 18 in a pole or similar, opened so that the cable or similar to be pulled out can be inserted into the pulling and supporting body 11, 12 (thus without a locking body on this stage), after which the part 12 is turned towards the part 11 until the body 11, 12 is in its closed position, after which locking takes place in this position by means of the wing screw 17. The cable can now be pulled out through the body 11, 12 to its calculated position. When this has been achieved, the body 11, 12 is opened, the cable is temporarily moved to rest exclusively against the now slightly hanging part 12,

et låselegeme 31, 32 monteres på kabelen og forskyves slik at det kommer midt foran legemet 11, 12, hvorpå til slutt låselegemet med kabelen forskyves til anlegg mot delen 11 og delen 12 dreies til anlegg mot delen 11 og fastlåses. Anordningens trekk-funksjon er dermed avsluttet og den fungerer videre som opphengningsanordning for kabelen. a locking body 31, 32 is mounted on the cable and moved so that it comes in front of the body 11, 12, after which finally the locking body with the cable is moved to abut against the part 11 and the part 12 is turned to abut against the part 11 and locked. The device's pulling function is thus finished and it continues to function as a suspension device for the cable.

Fig. 5 viser skjematisk det øyeblikk da låselegemet 31, 32 Fig. 5 schematically shows the moment when the locking body 31, 32

er montert på kabelen 50 og kombinasjonen låselegeme - kabel akkurat skal forskyves mot delen 11. is mounted on the cable 50 and the combination locking body - cable must be moved exactly towards part 11.

Av fig. 5 fremgår tydelig det faktum at når anordningen åpnes stopper den i en "halvåpen" stilling, hvorved den vridbare delen fungerer som støtte for kabelen, linen eller lignende under montasjen. From fig. 5 clearly shows the fact that when the device is opened it stops in a "half-open" position, whereby the rotatable part acts as a support for the cable, line or the like during assembly.
