Description

Oppfinnelsens område Field of the invention

Den foreliggende oppfinnelse vedrører en rørklemme, omfattende et hus med en indre del hvori er opptatt samvirkende gripe/holdekiler, hvilke kiler er forskyvbart anordnet i forhold til hverandre for å gripe eller holde et rør. The present invention relates to a pipe clamp, comprising a housing with an inner part in which interacting gripping/holding wedges are occupied, which wedges are displaceably arranged in relation to each other in order to grip or hold a pipe.

Kjent teknikk Known technique

NO patentpublikasjon 153 865 vedrører et kilearrangement som kan settes ned i et borebord eller en annen innretning. For fjerning av kilene må arrangementet løftes opp og åpnes, dvs. tas ut fra borestrengen. NO patent publication 153 865 relates to a wedge arrangement that can be set down in a drilling table or other device. To remove the wedges, the arrangement must be lifted up and opened, i.e. removed from the drill string.

Ved den foreliggende anordning kan man skifte kilestørr-else uten å fjerne holdedelen, dvs. at borestrengen eller annet rør kan fortsatt være igjen og strekke seg gjennom holdedelen under skifting av kilestørrelse. Dette vil være gunstig der man bruker borestrenger der elementer i strengen har forskjellig ytterdiameter. With the present device, the wedge size can be changed without removing the holding part, i.e. the drill string or other pipe can still remain and extend through the holding part while changing the wedge size. This will be beneficial where drill strings are used where elements in the string have different outer diameters.

Omtale av oppfinnelsen Mention of the invention

Rørklemmen ifølge oppfinnelsen er karakterisert ved at huset har åpninger, og at kilene kan dreies om husets akse mellom en bruksstilling og en stilling ut for åpningene gjennom hvilke de nedre kiler kan uttrekkes for utskiftning. The pipe clamp according to the invention is characterized in that the housing has openings, and that the wedges can be rotated about the axis of the housing between a position for use and a position out of the openings through which the lower wedges can be pulled out for replacement.

Et ytterligere trekk ved oppfinnelsen går ut på at den omfatter et eller flere sett med gripe/holdekiler, idet hvert sett omfatter en flerhet av gripe/holdeelementer, f.eks. fire, anordnet med passende omkretsavstand, f.eks. 90° . A further feature of the invention is that it comprises one or more sets of gripping/holding wedges, each set comprising a plurality of gripping/holding elements, e.g. four, arranged with suitable circumferential distance, e.g. 90°.

Oppfinnelsen vil i det følgende bli omtalt nærmere under henvisning til de vedføyde tegningsfigurer. The invention will be discussed in more detail below with reference to the attached drawings.

Kort omtale av fcegninqsfiqurene Brief mention of the fcegninqsfiqures

Figurene 1-4 viser henholdsvis sideriss, sidesnitt, grunnriss og tverrsnitt av et sett med gripe/holdekiler, f.eks. et øvre sett, idet gripe/holdekilene er vist i posisjon helt/delvis tilrettelagt for rørhåndterings-drift. Figur 5 viser samme snitt som figur 4, men med gripe/- holdekilene dreiet 45° for eventuell utskiftning av til-hørende deler. Figures 1-4 respectively show a side view, side section, ground view and cross section of a set of gripping/holding wedges, e.g. an upper set, the gripping/holding wedges being shown in a position fully/partially adapted for pipe handling operation. Figure 5 shows the same section as Figure 4, but with the gripping/holding wedges turned 45° for possible replacement of associated parts.

Beskrivelse av utførelsesformer Description of embodiments

På de vedføyde tegninger det vist en ikke-begrensende utførelsesform for en rørklemme, spesielt for vedlikehold av brønner, hvilken rørklemme 1 omfatter en første gripe/holdeinnretning 2a som kan være anordnet på linje 3C med en andre ikke vist innretning og som kan forskyves i forhold til hverandre for styrt transport av et rør deri-mellom. In the attached drawings there is shown a non-limiting embodiment of a pipe clamp, especially for the maintenance of wells, which pipe clamp 1 comprises a first gripping/holding device 2a which can be arranged on line 3C with a second device not shown and which can be displaced in relation to each other for controlled transport of a pipe in between.

Gripe/holdeinnretningen 2a omfatter gripe/holdekiler 4a, 4b anordnet i en indre del 5 som kan opptas i et hus 6, og at den indre del og/eller huset 5, 6 er innrettet for relativ dreining, figur 4, figur 5, om nevnte linje 3C, spesielt for utskiftning av gripe/holdekiler 4a, 4b. The gripping/holding device 2a comprises gripping/holding wedges 4a, 4b arranged in an inner part 5 which can be accommodated in a housing 6, and that the inner part and/or the housing 5, 6 is arranged for relative rotation, Figure 4, Figure 5, if said line 3C, especially for the replacement of gripping/holding wedges 4a, 4b.

Den indre del 5 er gjort dreibart i det ytre hus 6 for dreining mellom en bruksstilling, figur 4, og en utskifte-stilling, figur 5, og at det ytre hus 6 er utført med åpninger 7 for i utskifte-stillincf av den indre del 5 å tillate obstruksjonsfri utskiftning av gripe/holdekilene 4a, 4b. The inner part 5 is made rotatable in the outer housing 6 for rotation between a use position, Figure 4, and a replacement position, Figure 5, and that the outer housing 6 is designed with openings 7 for the replacement position of the inner part 5 to allow obstruction-free replacement of the gripping/holding wedges 4a, 4b.

Hver gripe/holdeinnretning 2a omfatter et eller flere sett med gripe/holdekiler 4a, 4b, idet hvert sett omfatter en flerhet av gripe/holdekiler, f.eks. fire, anordnet med passende omkretsavstand, f.eks. 90°. Each gripping/holding device 2a comprises one or more sets of gripping/holding wedges 4a, 4b, each set comprising a plurality of gripping/holding wedges, e.g. four, arranged with suitable circumferential distance, e.g. 90°.

Det ytre hus 6 omfatter løsbare lådeorganer 8 for de indre gripe/holdekiler 4a, 4b, hvilke låseorganer 8 er montert i huspartier 9 som mellom seg definerer utskift-ningsåpninger 7 for løsgjørbare gripe/holdekiler 4a, 4b. The outer housing 6 comprises detachable box members 8 for the inner grippers/holding wedges 4a, 4b, which locking members 8 are mounted in housing parts 9 which between them define replacement openings 7 for detachable grippers/holding wedges 4a, 4b.

Som nevnt er den indre del 5 og/eller ytre hus 6 innrettet for relativ dreining, og dette gjøres mulig ved at nevnte løsbare låseorganer 8, eller håndtak, som i bruksstilling, se figur 2, rager inn i gripe/holdekilene 4a, trekkes ut, se figur 5. Før uttrekkingen av låseorganene 8, kan de innerste kilehalvdeler 4a løftes noe i forhold til de ytre kilehalvdeler 4b, f.eks. ved hjelp av sylind-re 8a, slik at kilevirkningen mot det aktuelle rør 3 oppheves, se figur 2, spesielt til høyre på nevnte figur, samtidig som kilehalvdelene 4a og 4b fortsatt er i inn-grep med hverandre. As mentioned, the inner part 5 and/or outer housing 6 is arranged for relative rotation, and this is made possible by the said detachable locking means 8, or handles, which in the position of use, see figure 2, project into the grip/holding wedges 4a, are pulled out , see figure 5. Before the extraction of the locking members 8, the innermost wedge halves 4a can be lifted somewhat in relation to the outer wedge halves 4b, e.g. by means of cylinder 8a, so that the wedge effect against the tube 3 in question is cancelled, see figure 2, especially to the right of said figure, while the wedge halves 4a and 4b are still in engagement with each other.

På dette stadium, se spesielt figur 5, kan den innerste del 5 dreies i forhold til det ytre hus 6, dvs. kiledel-ene 4a, 4b kan dreies til sin utskifte-stilling for å tillate obstruksjonsfri utskiftning av nevnte gripe/hol-dekiler 4a, 4b, se figur 5, og spesielt pilen P. At this stage, see in particular figure 5, the innermost part 5 can be rotated in relation to the outer housing 6, i.e. the wedge parts 4a, 4b can be rotated to their replacement position to allow obstruction-free replacement of said gripping/holding wedges 4a, 4b, see figure 5, and especially the arrow P.

Dreiningen av den indre del 5 vil, som nevnt tidligere, finne sted om den vertikale akse 3C gjennom senter av begge deler 5 og huset 6. The rotation of the inner part 5 will, as mentioned earlier, take place about the vertical axis 3C through the center of both parts 5 and the housing 6.

Passende kan en slik gripe/holdeinnretning være montert på en vedlikeholdsenhet eller rørskruingsenhet, hvilken enhet er utført med en påbygget heis, spesielt en vogn-lignende heis med en hev- og senkbar samt svingbar og dreibar rørhåndteringsenhet. Appropriately, such a gripping/holding device can be mounted on a maintenance unit or pipe screwing unit, which unit is made with an attached lift, in particular a trolley-like lift with a raise and lower as well as pivotable and rotatable pipe handling unit.
