Abstract
Patente de Invenção: <B>"ACOPLAMENTO MECâNICO ASCENDENTE E PROCESSO"<D>. Um acoplamento mecânico ascendente tipo pino e caixa 10 é provido com um ressalto de pino anular externo 45 que engata a extremidade anular 44 da conexão de caixa 12 quanto o acoplamento for inicialmente engatado. O acoplamento 10 é uma conexão adequada para seções tubulares de um tubo ascendente que se estende a partir da estrutura de perfuração acima da superfície da água para o leito de mar. As tranquetas 22 conduzidas na conexão de caixa 12 são ajustadas radialmente para engatarem e travarem a caixa ao pino. As superfícies de apoio cónicas 38, 39, 40, 41 formadas nas tranquetas e no pino engatam e forçam o pino e a caixa entre si, na medida em que as tranquetas forem radialmente ajustadas. O engate do ressalto de pino externo e da caixa detém o movimento do pino e da caixa um na direção do outro, de modo que o ajuste contínuo das tranquetas proporcionem uma maior pressão de apoio de pré-carga entre os ressaltos de pino e caixa. O engate total do ressalto de extremidade de caixa e o ressalto de pino anular externo permitem a aplicação de uma grande força de pré-carregamento, impedem que as tranquetas distorçam a caixa, protegem a área de sobreposição entre o pino e a caixa de contaminação e proporcionam uma confirmação visual positiva do engate de ressalto.Invention Patent: <B> "ASCENDING MECHANICAL COUPLING AND PROCESS" <D>. A pin and box 10 upward mechanical coupling is provided with an external annular pin shoulder 45 which engages the annular end 44 of the box connection 12 when the coupling is initially engaged. Coupling 10 is a suitable connection for tubular sections of a riser that extends from the drilling structure above the water surface to the seabed. The catches 22 conducted in the housing connection 12 are radially adjusted to engage and lock the housing to the pin. The conical support surfaces 38, 39, 40, 41 formed on the pins and pin engage and force the pin and the box together, as the pins are radially adjusted. The engagement of the external pin shoulder and the housing stops the movement of the pin and housing in the direction of the other, so that the continuous adjustment of the latches provide a greater pre-load support pressure between the pin and housing lugs. The total engagement of the box end shoulder and the external annular pin shoulder allow the application of a great preload force, prevent the catches from distorting the box, protect the overlap area between the pin and the contamination box and provide positive visual confirmation of the cam hitch.
