The invention discloses a mounting structure for a lifting gear box of an ocean platform. The mounting structure comprises the ocean platform and a mounting rack welded together, wherein the mountingrack is U-shaped and comprises a front panel and a back panel, and the front panel and the back panel of the mounting rack are separately located on the front and back sides of the lifting gear box; afront mounting flange and a back mounting flange are also separately arranged on the front and back sides of the lifting gear box, the front mounting flange and the back mounting flange are mounted on the outer side of the mounting rack and are separately attached to the front and back panels of the mounting rack, a base plate is also arranged on the inner side of the mounting rack and is attached to the inner side of the mounting rack, and the front mounting flange and the back mounting flange, the front and back panels of the mounting rack and the base plate are pre-locked through a plurality of fasteners. According to the mounting mechanism, the mounting process is simple, the field operation time is shortened, the operation strength is reduced, the stress state is excellent, and the safety coefficient of the mounting flange is improved.
Description
technical field [0001] The invention belongs to the field of marine equipment, and more specifically relates to a mounting structure for a lifting gear box of an offshore platform. Background technique [0002] The installation of traditional self-elevating offshore platform lifting gearboxes is mostly simply fixed by bolts, and the lifting force and torque are borne and balanced by the wedge blocks around the mounting flange or the torsional block structure of the mounting frame in contact with the four wings of the flange. For the installation type carried by the wedge block or the torsion block, in order to meet the use requirements during the shipyard's on-site operation, it is necessary to match the contact surface of the wedge block or block on site to achieve a tight fit of the contact surface. [0003] For example, the lifting device in ZL200820070565.7 relies on the four wings of the flange to transmit the torque borne by the ring gear. [0004] The lifting gear bo...
