Abstract

The present invention provides a hydraulic pin hole type lifting system. The hydraulic pin hole type lifting system is applicable to water platforms. A water platform consists of a platform main body and spud legs with pin holes. The hydraulic pin hole type lifting system comprises a plurality of lifting mechanism sets. Each lifting mechanism set is matched with a spud leg. Each lifting mechanism set consists of a lifting frame, a guide device, a guide frame, a main lifting gear and an auxiliary lifting gear. The lifting frame is fixedly disposed on the platform main body. The guide device is disposed on the lifting frame; the guide device is matched with the spud legs; and the spud legs can go up and down along the guide device. The guide frame is disposed on the lifting frame. The main lifting gear and the auxiliary lifting gear are disposed on the guide frame and positioned in the lifting frame, wherein the main lifting gear consists of a main lifting oil cylinder and a high-position dwell pin mechanism with high-position plug pins, and the auxiliary lifting gear consist of an auxiliary lifting oil cylinder and a low-position dwell pin mechanism with low-position plug pins. The hydraulic pin hole type lifting system provided by the present invention has a high lifting speed and a strong lifting capability.

Description

technical field [0001] The invention relates to the technical field of water platform lifting, in particular to a hydraulic pin-hole lifting system. Background technique [0002] Jack-up platform or engineering ship is mainly composed of platform / hull, legs, lifting system and living building. When this type of self-elevating platform or engineering ship is working, use the lifting system to lift the platform / hull above the sea surface, and rely on the support of the legs to stand on the seabed for operation; after the operation is completed, lower the platform / hull to the sea surface, and then Pull up the legs and then tow to the next working position. The system used to drive the relative movement between the platform / hull and the legs is called the lifting system. The lifting system mainly includes rack and pinion type and hydraulic pin hole type. The rack-and-pinion lifting system has a short service life and is not suitable for occasions that require frequent lifting...
