A quick release device for soft rigid arm and mooring leg in single point mooring system

Abstract

The invention discloses a device for quick release of a soft yoke and a mooring leg in a single-point mooring system and relates to the technical field of single-point mooring. A hydraulic pump station is adopted to pull a guide pin shaft to move, so that quick release of the soft yoke and the mooring leg in the single-point mooring system is achieved. The device comprises a hydraulic pump station, a guide base, a guide pin shaft, a lug ring head, an installation support, a hydraulic cylinder and a support platform. In the action of quick release, the hydraulic pump station provides a power source to drive the hydraulic cylinder to move, the hydraulic cylinder is assembled on the installation support, the lug ring head is connected with the guide pin shaft and a piston rod of the hydraulic cylinder, and the guide pin shaft, the guide base and the hydraulic cylinder are coaxially installed; in this way, borne friction force is reduced during pulling of the guide pin shaft, time for pulling out of the pin shaft is shortened, and quick release of the soft yoke and the mooring leg in the single-point mooring system is achieved. The device is simple in structure and ingenious in concept; the reliability and safety of the single-point mooring system are improved; meanwhile, production is easy, assembly and replacement are convenient, and manufacturing cost can be reduced greatly.

Description

technical field [0001] The invention relates to the technical field of single point mooring, in particular to a quick release device for a soft rigid arm and a mooring leg in a single point mooring system. Background technique [0002] The single point mooring system (Single Mooring System, SPM), its main function is to locate the offshore floating device in the predetermined sea area, and plays the functions of transporting fluid, electricity, communication, etc., and at the same time, makes the offshore floating device have the effect of a wind vane , Under the action of various winds, waves and currents, the force on the offshore floating device is the smallest, so as to ensure the long-term continuous operation of the offshore floating device on the sea. The release of the soft rigid arm and the mooring leg in the single point mooring system is to ensure that the offshore floating device and the single point mooring system mooring tower are quickly separated before the o...

AI Technical Summary

Problems solved by technology

Because the circumferential clear distance between the guide pin shaft and the mooring leg sleeve is very small in the prior art, it is difficult to pull out the guide pin shaft only by adjusting the hoisting cable of the soft rigid arm and the universal joint cable in the mooring leg. out, it is necessary to add a device to promote the movement of the guide pin
