Abstract

The invention relates to a lifting pull-plug pin system of self-installed production platform of a one-pile multi-cylinder pull-plug pin in lifting of a marine production platform. The lifting pull-plug pin system comprises 32 pull-plug pin hydraulic cylinders, 32 platform main pin shafts, a hydraulic control system of a pull-plug pin hydraulic cylinder and an electrical control system, wherein an oil pump motor group of the hydraulic control system of the pull-plug pin hydraulic cylinder is connected with the pull-plug pin hydraulic cylinders through a three-position four-way electromagnetic change-over valve after being connected with an electromagnetic overflow valve bank and a pressure transformer in series, the telescopic end of each pull-plug pin hydraulic cylinder is fixedly connected with a pull-plug pin hydraulic cylinder pin shaft, each pull-plug pin hydraulic cylinder pin shaft is fixedly connected with a platform main pin shaft, the electrical control system comprises a programmable controller PLC and a monitoring device which is arranged in the pull-plug pin hydraulic cylinder for monitoring whether the platform main pin shaft is plugged to a correct position, and the monitoring device is connected with the programmable controller PLC. The synchronous control precision of the 32 pull-plug pin hydraulic cylinders and the stability of the system are high.

Description

technical field [0001] The present invention relates to the technical field of leg locking, plugging and unpinning system in the hydraulic lifting system of marine self-installation platform, in particular to a self-installation oil production platform lifting and plugging pin system for a multi-cylinder plugging and unplugging system in the process of lifting and lowering the offshore oil production platform . Background technique [0002] The function of the self-installation oil production platform hydraulic lifting plug pin system is to control the platform leg plugging and pulling piles when lifting the platform. It is divided into three parts: the lifting pin pile driver system, the plugging hydraulic control system and the control system. The hydraulic device works relatively smoothly. Due to its light weight, small inertia and quick response, the hydraulic device is easy to realize quick start, brake and frequent reversing. Hydraulic transmission is easy to automate...
