Embodiment 1

[0035] The embodiment of the present invention provides an offshore platform lifting mechanism, such as figure 1 As shown, the lifting mechanism includes: a rack 1, a mounting frame (not shown) and a plurality of climbing gears 2, the rack 1 is fixedly installed on the legs of the offshore platform, and the rack 1 is mounted along the legs (not shown) The installation frame is fixedly installed on the platform body (not shown in the figure) of the offshore platform at the position corresponding to the legs, and a plurality of climbing gears 2 are respectively rotatably installed in the mounting frame. The rack 1 meshes, and a plurality of climbing gears 2 are arranged symmetrically with the center line of the rack 1 as the axis. The two sides of the rack 1 are respectively arranged with tooth rows 11, and each tooth row 11 is arranged along the length direction of the rack 1. Each tooth The tooth profile parameters of the rows 11 are the same, and there is a phase difference H...

Abstract

The invention discloses an ocean platform lifting mechanism and an ocean platform, and belongs to the technical field of ocean engineering. The lifting mechanism comprises a rack, a mounting frame and multiple climbing gears; the rack is fixedly mounted on a pile leg of the ocean platform, and is arranged in the length direction of the pile leg; the mounting frame is fixedly mounted on a platform body of the ocean platform corresponding to the position of the pile leg; the multiple climbing gears are rotationally mounted in the mounting frame, are respectively engaged with the rack, and are symmetrically arranged with the center line of the rack as axis; tooth rows are respectively arranged on two side edges of the rack; each tooth row is arranged in the length direction of the rack, and has the same tooth shape parameters; and the tooth row on one side edge of the rack and the tooth row on the other side edge of the rack have a phase difference. The lifting mechanism solves the problem of reduction of the structure stability of the mounting frame due to the height difference of the climbing gears.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and in particular relates to an ocean platform lifting mechanism and an ocean platform. Background technique [0002] Offshore platform is a common marine engineering equipment, which can be divided into rack and pinion lifting mechanism and pin lifting mechanism according to different lifting mechanisms. [0003] The rack and pinion lifting mechanism includes a rack, multiple climbing gears and a mounting frame. The rack is mounted on the legs of the offshore platform, the mounting frame is mounted on the main body of the offshore platform, and multiple climbing gears are rotatably mounted on the mounting frame. Inside, multiple climbing gears mesh with the rack, and the multiple climbing gears are arranged symmetrically with the center line of the rack. [0004] During the working process of the lifting mechanism, if the arrangement of each climbing gear and rack is exactly the same,...
