The invention relates to an arrangement and to a method related to a swing
damper, particularly to a swing damper (1) for supporting a tool (5) that
hangs from a crane arm (2) or some similar structure. The swing damper (1)
includes an upper part (11), which is connected to the crane arm (2), and a
lower part (12) that carries a work tool (5) or some similar device either
directly or via a rotator (4) for instance. The upper part (11) and the lower
part (12) are pivotally interconnected via a pivot joint (13), wherewith the
swing damper (1) includes a brake arrangement (50) in the form of a male-
female-cone arrangement. Either the upper part (11) or the lower part (12)
carries two mutually opposing female cones (52, 53). The part that lacks the
female cones carries two mutually opposing male cone parts (60, 61). The
conical surfaces of the male cone parts and the female cones are in mutual
contact in effecting a braking operation, and the conical surfaces of the male
cone parts and the female cones also function as bearing surfaces between the
upper part (11) and the lower part (12). An outer portion (64, 65) of the male
cone parts (60, 61) functions to transfer load to that part which lacks said
female cones (52, 53).
La présente invention concerne un mécanisme et un procédé associés à un amortisseur d'oscillation, en particulier à un amortisseur d'oscillation (1) destiné à supporter un outil (5) suspendu depuis le bras (2) d'une grue ou une structure similaire. L'amortisseur d'oscillation (1) comprend une partie supérieure (11) qui est raccordée au bras de grue (2), et une partie inférieure (12) qui porte un outil de travail (5) ou autre dispositif similaire, directement ou par l'entremise d'un rotateur (4), par exemple. Les parties supérieure (11) et inférieure (12) sont reliées de façon pivotante via une articulation à pivot (13), grâce à laquelle l'amortisseur d'oscillation (1) comprend un mécanisme de frein (50) se présentant sous la forme d'un agencement de cônes mâle-femelles (60,61). La partie supérieure (11) ou la partie inférieure (12) supporte deux cônes femelles (52,53) opposés l'un à l'autre. La partie qui ne supporte pas les cônes femelles supporte deux parties opposées de cône mâle (60,61). Les surfaces coniques des parties du cône mâle et des cônes femelles se trouvent en contact les unes avec les autres lors d'une opération de freinage, et elles fonctionnent également comme surfaces de roulement entre la partie supérieure (11) et la partie inférieure (12). Une section extérieure (64,65) des parties de cône mâle (60,61) sert à transférer la charge sur la partie qui ne supporte pas les cônes femelles (52,53).
