Abstract

The invention discloses a reduction device of a rack and pinion lifting system and a rack and pinion lifting system, which belong to the technical field of marine engineering. The reduction device includes climbing gear shaft, climbing pinion, front bearing sleeve, rear bearing sleeve, and mounting flange. The outer circle of the bearing sleeve, the outer circle of the rear bearing sleeve and the mounting flange are set concentrically, and the mounting flange is respectively connected with the rear bearing sleeve and the mounting frame. The front bearing sleeve and the rear bearing sleeve are eccentric structures, and the eccentric direction of the front bearing sleeve is consistent The eccentric direction of the rear bearing sleeve is consistent, the eccentric direction of the front bearing sleeve is opposite to the deviation direction of the mounting flange connection position, the distance between the outer center of the front bearing sleeve and the inner center of the front bearing sleeve, the outer center of the rear bearing sleeve and the The distance between the inner circle centers of the rear bearing sleeves is equal to the deviation distance of the connection position of the mounting flange caused by the welding deformation of the mounting frame. The safety of the invention is improved.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a reduction device for a rack-and-pinion lifting system and the rack-and-pinion lifting system. Background technique [0002] The lifting system is a key component of the offshore jack-up offshore platform, and the performance of the lifting device directly affects the safety performance and service life of the jack-up offshore platform. The lifting system is installed at the junction of the platform body and the legs of the self-elevating offshore platform. It can make the legs and the platform body move up and down relative to each other, or fix the platform body at a certain position of the legs. Commonly used lifting systems include hydraulic pin type and rack and pinion type. [0003] Among them, the rack-and-pinion lifting system includes a mounting frame, a rack, a power device and a reduction device. The reduction device includes a climbing pinion. The reducti...
