Description

Rorkobliiigsanordning med eksenterlås. Rudder coupling device with eccentric lock.

Foreliggende oppfinnelse angår en rør-koblingsanordning bestående av to eller flere med hverandre leddbart forbundne deler, som er anordnet til i koblingsstilling ringformig å omslutte de av anordningen sammenkoblede, mot hverandre vendende rør-ender. Det vesentlig karakteristiske ved oppfinnelsen er at delene er anordnet til å lukkes ringformig sammen ved hjelp av en med en spennarm forsynt lås utstyrt med et sperreorgan, som er anordnet til ved spennarmens svingning til låsestilling automatisk å sperre spennarmen, så at denne ikke kan svinges til låsens åpningsstilling, samt at sperreorganet er manuelt førbart ut av sperrestillingen for å muliggjøre spennarmens svingning til låsens åpningsstilling. The present invention relates to a pipe coupling device consisting of two or more articulatedly connected parts, which are arranged in the coupling position to annularly enclose the opposite pipe ends connected by the device. The essential characteristic of the invention is that the parts are arranged to be closed together annularly by means of a lock provided with a tension arm equipped with a locking device, which is arranged to automatically block the tension arm when the tension arm swings into the locking position, so that it cannot be swung to the lock's open position, and that the locking device can be manually moved out of the locking position to enable the tension arm to swing to the lock's open position.

Oppfinnelsen vil nærmere bli beskrevet i tilslutning til hosstående tegning, som viser en som eksempel valgt utførelsesform av rør-koblingsanordningen ifølge oppfinnelsen. Fig. 1 viser koblingsanordningen sett forfra, delvis i snitt, og The invention will be described in more detail in connection with the accompanying drawing, which shows an exemplary embodiment of the pipe coupling device according to the invention. Fig. 1 shows the coupling device seen from the front, partly in section, and

Fig. 2 viser samme sett fra siden. Fig. 2 shows the same set from the side.

Med 1 betegnes koblingsringen, som ifølge den viste utførelsesform er delt i et aksialplan i to halvdeler 2 og 3, som i sine ene ender er leddbart forbundet med hverandre ved 4. Halvdelene 2 og 3 er i sine motsatte ender forsynt med en eksenterlås 5, ved hjelp av hvilken halvdelene 2 og 3 er anordnet til ringformig å lukkes om de mot hverandre vendende rørender, som anordningen skal sammenkoble. 1 designates the coupling ring, which according to the embodiment shown is divided in an axial plane into two halves 2 and 3, which at one end are hingedly connected to each other at 4. The halves 2 and 3 are provided at their opposite ends with an eccentric lock 5, by means of which the halves 2 and 3 are arranged to be annularly closed around the pipe ends facing each other, which the device is to connect.

Eksenterlåsen 5, som omfatter en spennarm 6, er forsynt med et spennorgan 7, som er anordnet til ved spennarmens 6 svingning til låsestilling automatisk å sperre spennarmen 6, så at denne ikke kan svinges til eksenterlåsens 5 åpningsstilling. Sperreorganet 7 er imidlertid manuelt førbart ut av sperrestilling for å muliggjøre spennarmens 6 svingning til eksenterlåsens 5 åpningsstil-. ling. The eccentric lock 5, which comprises a tension arm 6, is provided with a tensioning member 7, which is arranged to, when the tension arm 6 swings to the locking position, automatically block the tension arm 6, so that it cannot be swung to the eccentric lock 5's open position. However, the locking member 7 can be manually moved out of the locking position to enable the tension arm 6 to swing to the eccentric lock 5's opening position. ling.

Ifølge den viste utførelsesform er de to halvdeler 2 og 3 forsynt med utspring 8 og 9, med hvilke eksenterlåsen 5 står i inngrep. Gjennom utspringet 8 på halvdelen 2 går en aksel 10, på hvilken et par armer 11 er leddbart lagret ved siden av utspringet 8. Disse armer 11 er i sine fra akselen 10 vendende ender forbundet med en aksel 12, på hvilken spennarmen 6 er leddbart lagret mellem armene 11. Spennarmen 6 består av to i avstand fra hverandre anordnede grener, og akselen 12 går gjennom begge disse grener. På akselen 12 mellem grenene er sperreorganet 7, som består av en sperreplate, svingbart lagret. According to the embodiment shown, the two halves 2 and 3 are provided with protrusions 8 and 9, with which the eccentric lock 5 engages. Through the protrusion 8 on the half 2 runs a shaft 10, on which a pair of arms 11 are hingedly mounted next to the protrusion 8. These arms 11 are connected at their ends facing away from the shaft 10 to a shaft 12, on which the tension arm 6 is hingedly mounted between the arms 11. The tension arm 6 consists of two branches arranged at a distance from each other, and the shaft 12 passes through both of these branches. On the shaft 12 between the branches, the locking member 7, which consists of a locking plate, is pivotally mounted.

Spennarmen 6 er ved sitt lagringspunkt på akselen 12 utformet til en eksenter 13, som er anordnet til ved låsingen å gripe inn i en uttagning 14 eller lignende i halvdelens 3 utspring 9. At its storage point on the shaft 12, the tension arm 6 is designed into an eccentric 13, which is arranged to engage in a recess 14 or the like in the projection 9 of the half 3 during locking.

Sperreplaten 7 samvirker med en fjær 15, som i spennarmens 6 låsestilling tvinger sperreplaten 7 til anlegg mot et utenfor uttagningen 14 anordnet anslag 16 eller lignende, så at spennarmen 6 ikke kan svinges til eksenterlåsens 5 åpningsstilling. I denne stilling ligger sperreplaten 7 ved fjærens 15 virkning an mot et på spennarmen 6 anordnet anslag '17, som vist i fig. 1. The locking plate 7 cooperates with a spring 15, which in the locking position of the clamping arm 6 forces the locking plate 7 to abut against a stop 16 arranged outside the socket 14 or the like, so that the clamping arm 6 cannot be swung to the eccentric lock 5's open position. In this position, due to the action of the spring 15, the locking plate 7 rests against a stop '17 arranged on the tension arm 6, as shown in fig. 1.

Når koblingen skal åpnes trykkes sperreplaten 7 mot fjærens 15 virkning inn mot spennarmen 6 fra anslagene 16 og 17, så at sperreplaten 7, som i forhold til akselen 12 When the coupling is to be opened, the locking plate 7 is pressed against the action of the spring 15 against the tension arm 6 from the stops 16 and 17, so that the locking plate 7, which in relation to the shaft 12

i hovedaksen har samme eksentriske form in the main axis have the same eccentric shape

som spennarmens 6 eksenter 13, kommer til which the clamping arm's 6 eccentrics 13, come to

å gripe inn i uttagningen 14 i utspringet 9, to intervene in the recess 14 in the outlet 9,

hvorved spennarmen 6 er svingbar til eksenterlåsens 5 åpningsstilling. Herved likesom whereby the tension arm 6 is pivotable to the eccentric lock 5's opening position. Hereby as well

ved påbegynt låsing griper således eksenteren 13 og sperreplaten 7 som en enhet inn when locking has begun, the eccentric 13 and the locking plate 7 thus engage as a unit

i uttagningen 14. in the selection 14.

Oppfinnelsen er ikke begrenset til det The invention is not limited thereto

ovenfor beskrévne og det på tegningen viste, described above and what was shown in the drawing,

men kan forandres på flere måter innenfor but can be changed in several ways within

rammen av efterfølgende patentpåstander. the scope of subsequent patent claims.

Således kan f. eks. koblingsringen 1 bestå Thus, e.g. coupling ring 1 pass

av flere enn to med hverandre leddbart forbundne deler og fjæren 15 unnværes, hvis of more than two articulated parts and the spring 15 is omitted, if

sperreplaten 7 forsynes med en på tilsva-rende måte virkende motvekt eller lignende. the locking plate 7 is supplied with a counterweight or similar acting in a similar manner.

For oppfinnelsen er det naturligvis uvesent-lig om koblingsringen er forsynt med tet-ningsring eller om denne, i tilfelle tetnings-ring behøves, er anordnet til å anbringes direkte på rørene. Det er dessuten uvesent-lig om koblingsringen er anordnet til å sam-virke med på rørendene anordnede ringfor-mede kraver, konisk utvidede rørender eller For the invention, it is of course immaterial whether the coupling ring is provided with a sealing ring or whether this, in the event that a sealing ring is required, is arranged to be placed directly on the pipes. It is also immaterial whether the coupling ring is arranged to cooperate with ring-shaped collars arranged on the pipe ends, conically extended pipe ends or

glatte rørender. smooth pipe ends.
