Abstract

En anordning ved en trekkbar broplugg (30) omfatter et ovre pakningselement (3) og et nedre pakningselement (11). Øvre pakningselement (3) er forbundet til et øvre ledd (6), som kan svinge om en forste bolt (5). Øvre ledd (6) er videre svingbart forbundet med et nedre ledd (8) ved en andre bolt (7). Nedre ledd (8) kan svinge om en tredje bolt (9). En vinkel (a) dannet mellom bropluggens langsgående akse og ei linje som går gjennom den forste bolten (5) og den andre bolten (7), hhv. gjennom den andre bolten (7) og den tredje bolten (9) er større enn null når øvre ledd (6) og nedre ledd (8) er inntrukket. Øvre ledd (6) og nedre ledd (8) er anordnet for ved setting å ekspandere radialt ved sammentrykking av øvre pakningsinnfesting (3) mot nedre pakningsinnfesting (12), til dannelse av mekanisk barriere for øvre pakningselement (3) og nedre pakningselement (11).
