Abstract

desconector semi-pantográfico. um desconector semi-pantográfico que compreende uma base (11) que suporta um sistema cinemático motor (12) um braço (13) que tem uma sapata (14) para pegar um derrubador (drooper) (15) e é articulado à base (11) de modo a ser capaz de oscilar para passar de maneira reversível de uma configuração de desconexão na qual o braço (13) está dobrado sobre a base (11) para a configuração de contato, na qual o braço (13) está dobrado sobre a base (11) para uma configuração de contato, na qual o braço (13) está separado da base (11) de modo a conectar por meio da sapata (14) ao derrubador (15), uma haste (16) que é conectada funcionalmente à sapata (14) para atuá-a, um dispositivo camo (17) para atuar a haste (16) que coordena de maneira cinemática a abertura da sapata (14) e uma primeira rotação do braço (13) a partir da configuração de desconexão para a configuração de contato, um dispositivo semi-pantográfico (18) que é conectado funcionalmente à haste (16), ao braço (13) e ao sistema cinemático motor (12) que define uma sequência cinemática para fechar a sapata (14) depos da primeira rotação do braço (13) e uma sequência cinemática para abertura da sapata (14)que é preliminar a uma segunda rotação do braço (13) que o move da configuração de contato para a configuração de desconexão.semi-pantographic disconnector. a semi-pantographic disconnector comprising a base (11) supporting a motor kinematic system (12) an arm (13) having a shoe (14) for catching a drooper (15) and is hinged to the base (11) ) to be able to swing reversibly from a disconnect configuration in which the arm (13) is bent over the base (11) to the contact configuration in which the arm (13) is bent over the base (11) for a contact configuration in which the arm (13) is separated from the base (11) so as to connect via the shoe (14) to the knocker (15), a rod (16) which is functionally connected to the shoe (14) for actuating it, a camo device (17) for actuating the rod (16) which kinematically coordinates the opening of the shoe (14) and a first rotation of the arm (13) from the disconnect configuration. for contact configuration, a semi-pantographic device (18) that is functionally connected to the stem (16), to the arm (13) and the motor kinematic system (12) which defines a kinematic sequence for closing the shoe (14) after the first rotation of the arm (13) and a kinematic sequence for opening the shoe (14) which is preliminary to a second rotation of the arm (13) that moves it from contact configuration to disconnect configuration.
