Abstract

The invention discloses a locking mechanism of a rack-and-pinion lifting system, and belongs to the drilling platforms fitting field; the locking mechanism comprises a mount, two first locking devices, and two second locking devices; the two first locking devices are symmetrically arranged on two sides of a pile leg tooth bar; the two second locking device are symmetrically arranged on two sides of the pile leg tooth bar; each first locking device comprises a first locking oblique piece, a first locking tooth piece, a first horizontal jack and a first vertical oil cylinder; each second locking device comprises a second locking oblique piece, a second locking tooth piece, a second horizontal jack and a second vertical oil cylinder; the second and first locking oblique pieces are same in structure. Two first locking tooth pieces in the locking mechanism bear force through oblique surfaces, and the oblique surfaces can transfer partial load to the horizontal jacks, thus reducing vertical load, so the large power high cost vertical jack in the prior art can be replaced by the small power low cost vertical oil cylinder.

Description

technical field [0001] The invention relates to the field of drilling platform accessories, in particular to a locking mechanism of a rack and pinion lifting system. Background technique [0002] The rack and pinion lifting system is an important device of the drilling platform. At present, the rack and pinion lifting system of the drilling platform in the world is equipped with an independent locking mechanism. In stormy conditions, the locking mechanism can firmly lock the pile legs and the drilling platform. To withstand loads in storm conditions. [0003] The locking mechanism of the existing rack and pinion lifting system includes a mounting frame, two horizontal jacks, two vertical oil cylinders, four vertical jacks, two wedge racks and four inclined blocks, and two wedge teeth The bars are all trapezoidal structures, and the bottoms of the trapezoids are arranged oppositely, and the bottoms of the trapezoids are provided with teeth that mesh with the leg racks, and t...
