Description

Technical Field

[0001] The invention belongs to the technical field of offshore hoisting, and in particular relates to a hoisting sling system suitable for offshore wind power steel pipe pile hoisting and turning construction. Background Art

[0002] Offshore wind power steel pipe pile foundation has the advantages of simple structure, short processing cycle, convenient installation, high construction efficiency, etc., and has been widely used in the field of offshore wind power construction at home and abroad. Since offshore construction is greatly affected by weather and sea conditions, ship and engine shaking is inevitable. In addition, the steel pipe pile foundation is heavy, large in diameter, and long in length. Once a collision or slippage occurs during the lifting process, it will be difficult to control. To ensure safety, the lifting must be completed quickly to separate the steel pipe pile from the transport ship.

[0003] The existing pile driving construction technology mostly uses double main hooks to turn over the steel pipe pile. One main hook is connected to the lifting ear of the steel pipe pile, and the other main hook is connected to the bottom of the pile. After the steel pipe pile is turned over, the entire load will be borne by the single main hook. However, for heavier steel pipe piles, the lifting capacity of the single main hook will not meet the requirements, and this technology is no longer applicable. Summary of the invention

[0004] The present invention is mainly to overcome the deficiencies of the prior art and provides a sling system suitable for offshore wind power steel pipe pile hoisting and turning construction.

[0005] The present invention is achieved through the following technical solutions:

[0013] Step 3: first lower the height of the auxiliary hook, and then use the manual traction rope to assist in control, clamp the tail clamp to the pile wall at the tail end of the steel pipe pile to be hoisted and turned over; then raise the height of the auxiliary hook until the fourth rope loop of the pile bottom hoisting rope group is stressed and in a straight state;

[0014] Step 5: The double main hooks and the auxiliary hooks are lifted simultaneously to lift the steel pipe pile horizontally off the deck of the transport ship. When the steel pipe pile is higher than the tire frame, the transport ship sails away;

[0015] Step 6: When the steel pipe pile is lifted and stabilized, the double main hooks are slowly lifted, and at the same time, the auxiliary hooks are lowered to start turning the steel pipe;

[0016] Step seven: when the tail end of the steel pipe pile contacts the seabed mud surface and the steel pipe pile turns over to 75° to 85°, the auxiliary hook stops lowering and the tail clamp is removed, and then the double main hooks continue to lift until the steel pipe pile is completely vertical.
