Abstract

The invention relates to a lifting device which can be reused. The device comprises a platform body, a guiding ring, a platform connecting body, a platform connecting pin, a movable pile fixing frame, a square beam, a ring beam push-pull cylinder bracket, a ring beam push-pull, a movable ring beam, a lifting cylinder, an upper row of push-pull cylinder, an upper row of push-pull cylinder bracket, an upper row of tooth block connecting body, a tooth block, a gear rack, a pile leg, a pile fixing frame connecting pin, a lower row of tooth block connecting body, a lower row of push-pull cylinder, a lower row of push-pull cylinder bracket, a ring beam guiding block and a pile fixing block. The force transmission and the relative movement between the platform body and the pile leg, and the lifting and the lowering of the platform are realized through the platform connecting body, the platform connecting pin, the movable pile fixing frame, the lifting cylinder, the ring beam, the square beam, the tooth block, and the gear rack. The tooth block and the gear rack are meshed through multiple teeth, the whole set of device is produced in a modularized way, and can be reused. The lifting device not only is secure and reliable, but also has low construction cost, thereby greatly saving the offshore construction expense time when be applied to a fixed platform.

Description

Technical field:

[0001] The invention relates to a platform lifting system applied in ocean or lake operations. Background technique:

[0002] With the exploration and development of marine resources, more and more offshore platforms are being built. Among them, in the shallow sea and even the middle and deep sea areas, the jack-up platform has the advantages of almost continuous work, stable operation and high efficiency in various sea conditions. It has been widely used and is the main platform in this sea area. The platform lifting device is the key part of the self-elevating platform, which is highly valued in the design and construction. The current lifting device generally adopts two forms: the cylinder jacking pin climbing rod type and the rack and pinion lifting device: the oil cylinder jacking pin climbing rod type The lifting device has disadvantages such as difficult insertion and removal of pins and difficulty in leveling the platform; the rack and pinion liftin...
