Abstract

La présente invention relève du domaine des appareils marins, et concerne en particulier un appareil de montage d'une plateforme marine. Afin de résoudre les problèmes existants selon lesquels, lors du montage d'une plateforme de production de pétrole, il est difficile d'utiliser une grue flottante à grande échelle pour effectuer des opérations en mer et l'inclinaison se produisant facilement, un appareil pour monter une plateforme marine est proposé. L'appareil comprend : une coque, un pont de bateau étant monté de manière fixe au sommet de la coque, deux côtés du pont de bateau sont tous deux pourvus de deux rainures télescopiques disposées symétriquement, des plaques de fixation sont reliées de manière coulissante dans les rainures télescopiques, la même tige filetée est en liaison filetée entre les deux plaques de fixation, une tige de support est reliée de manière coulissante sur la plaque de fixation, un coussin d'air flottant est monté de manière fixe à l'extrémité inférieure de la tige de support, une cavité de placement est disposée sur le pont de bateau, et un moteur électrique est monté de manière fixe sur une paroi interne d'un côté de la cavité de placement. L'appareil de montage d'une plateforme marine de la présente invention est facile à faire fonctionner et à utiliser, peut supporter de manière stable toute la coque, et peut également faciliter le support et le levage d'une plateforme de montage pour des personnes l'utilisant.
