An offshore platform lifting device

Abstract

The invention discloses an ocean platform lifting device and belongs to the field of ocean platform lifting. The ocean platform lifting device comprises spud legs, mounting bed frames movably arranged on the spud legs in a sleeving mode and fixedly connected with an ocean platform, and two lifting units sequentially arranged in the perpendicular direction. Racks are arranged on the spud legs. The two lifting units are arranged in the mounting bed frames. Each lifting unit comprises a lifting oil cylinder, a lifting block and a locking oil cylinder; the lifting oil cylinder is arranged in the perpendicular direction; the two ends of the lifting oil cylinder are rotatably connected with the corresponding mounting bed frame and the corresponding lifting block; a tooth surface is arranged on one side portion of the lifting block; the tooth surface can be engaged and locked with the corresponding rack through the corresponding locking oil cylinder; the locking oil cylinder is arranged in the horizontal direction; and the two ends of the locking oil cylinder are connected with the corresponding mounting bed frame and a cylinder block of the corresponding lifting oil cylinder. According to the embodiment, the areas of the rack for bearing loads on the spud legs are enlarged, so that the stability of load bearing is improved, and the ocean platform is lifted stably.

Description

technical field [0001] The invention relates to the field of offshore platform lifting, in particular to an offshore platform lifting device. Background technique [0002] With the continuous development of my country's offshore oil exploration, development and production, the demand for offshore platforms is becoming increasingly tense. Among them, in the lifting work of deep sea ocean, the application of rack and pinion lifting device is more and more extensive. [0003] The rack-and-pinion lifting device mainly includes a lifting unit, a leg and a rack set on the leg, and the lifting unit is usually composed of a driving motor and a crawling gear. The crawling gear is set at the output end of the driving motor. When the offshore platform is lifted , the number of contact teeth between the crawling gear and the rack arranged on the pile legs is small, so the bearing area of ​​the crawling gear and the rack is small, which affects the stability of the platform lifting. ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem of high manufacturing cost of the rack and pinion lifting device due to the small force-bearing area of ​​the crawling gear and the rack, an embodiment of the present invention provides a lifting device for an offshore platform
