Description

Technical Field

[0001] The utility model relates to the technical field of mooring anchors of offshore oil platforms and wind power platforms, in particular to a deep-sea pile anchor fin plate welding fixture. Background Art

[0002] As the exploration of marine resources is increasingly moving towards the deep sea, the deep-sea mooring anchoring scheme has greatly affected the installation efficiency of the mooring system. For geological areas with deep water and soft seabed soil environment, a gravity penetration mooring anchor can be used. Through free fall on the installation ship, the anchor body is driven into the seabed under the action of its own weight, thereby completing rapid mooring. This type of pile anchor structure includes four fin plates for stabilizing the penetration posture of the anchor body. The four fin plates need to maintain a certain verticality with the anchor body to ensure that their stabilizing posture can operate effectively. Due to the large size of the fin plate, a tooling is required during the welding process to ensure that the fin plate is always in a vertical state with the anchor body during the welding process.
