Abstract:
(EN) The present invention relates to a device for uncoupling a plug from a pulling head, said device comprising a main body (1) which, in turn, comprises an isolation chamber (32) formed by an isolating wall (31), said isolation chamber (32) comprising, in its interior, an element (21) for uncoupling a plug (8) relative to a pulling head (9), and a coupling element (4) adapted to keep a terminal edge of the isolating wall (31) in contact with a surface of the pulling head (9) such as to keep the isolation chamber (32) isolated from the external environment.
(FR) La présente invention concerne un dispositif de désaccouplement d’un bouchon d’une tête de traction, comprenant un corps principal (1), lequel comporte à son tour une chambre d’isolation (32) formée par une paroi d’isolation (31), la chambre d’isolation (32) comprenant intérieurement un élément de désaccouplement (21) du bouchon (8) par rapport à la tête de traction (9), et un élément d'accouplement (4) conçu pour maintenir un bord extérieur de la paroi d’isolation (31) en contact avec une surface de la tête de traction (9), de manière à maintenir la chambre d’isolation (32) isolée de l’environnement extérieur.
(PT) A presente invenção está relacionada a um dispositivo de desacoplamento de um bujão de uma cabeça de tração, compreendendo um corpo principal (1) que, por sua vez, compreende uma câmara de isolamento (32) formada por uma parede de isolamento (31), em que a câmara de isolamento (32) compreende em seu interior um elemento de desacoplamento (21 ) do bujão (8) em relação à cabeça de tração (9), e um elemento acoplador (4) adaptado para manter uma borda extrema da parede de isolamento (31) em contato com uma superfície da cabeça de tração (9), de modo a manter a câmara de isolamento (32) isolada do ambiente externo.
