Abstract

The invention discloses a gear and rack lifting device. The gear and rack lifting device comprises a driving gear box, a driving gear assembly, a driven gear assembly and an installation rack. The driving gear box, the driving gear assembly and the driven gear assembly are all installed on the installation rack. The driving gear box comprises a driving gear. The driving gear assembly comprises a first external gear, a second external gear and a first climbing gear. The first external gear, the second external gear and the first climbing gear are connected together in sequence in a coaxial manner. The first external gear is engaged with the driving gear. The driven gear assembly comprises a driven external gear and a second climbing gear. The driven external gear and the second climbing gear are connected together in a coaxial manner. The driven external gear is engaged with the second external gear. The first climbing gear and the second climbing gear are arranged side by side. Both the first climbing gear and the second climbing gear are used for being engaged with pile leg racks. According to the gear and rack lifting device, the bearing capacity of a gear and rack lifting systemis improved, and the manufacturing cost and maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a rack and pinion lifting device. Background technique [0002] The rack and pinion lifting system is a key part of the self-elevating offshore platform. The system usually includes components such as driving a variable frequency motor and a gear train. Under the action of the rack and pinion system, the pile legs are driven to realize the lifting or landing action of the offshore platform. The performance of the rack and pinion lifting system directly affects the working efficiency of the offshore platform, so it is extremely important for the optimal design of the device. [0003] The existing rack and pinion lifting system is a driving mode in which a variable frequency motor drives a gear box. When the offshore platform is working, multiple gear boxes are usually used to run together to drive the offshore platform to complete the lifting or landing action. [0004] In the pr...
