Description

Technical Field

[0001] The utility model relates to the technical field of sea wind turbine conductor rack hoisting devices, in particular to a low-space frame type hoisting device applied to a three-tube suction conductor rack. Background Art

[0002] After more than a decade of development, domestic offshore wind turbine foundations have evolved into various types, including high-pile cap foundations, single pile foundations, pile-group jacket foundations, suction tube foundations, and floating foundations. Suction tube foundations are a relatively new type, using suction tubes at the bottom of the frame to sink into the seabed under negative pressure, effectively avoiding the risk of deep soil uncertainty and offering fast installation, low construction noise, and easy recovery.

[0003] However, the existing jacket generally has an overall height of 80 meters to 100 meters and a weight of 2,000 tons to 2,600 tons. The distance between the floating crane main hook and the upper platform of the jacket is too large, which places high demands on the ship's machinery and equipment. The prior art also discloses a lifting device for a three-leg jacket of an offshore wind power foundation, which includes a lifting beam truss consisting of an upper and lower frame, three main risers and two auxiliary risers; the two auxiliary risers are respectively connected between the first and second chords of the upper and lower frames and the distance to the first top is one-third of the center distance between the two main risers; the four lifting ears on the lifting beam They are respectively installed on the top of the main riser located at the second and third top ends and the top of the two auxiliary risers; the three lower lifting eyes of the lifting beams are respectively installed at the bottom of the three main risers; the three lower slings are respectively hung between the three jacket lifting eyes and the three lower lifting eyes of the lifting beams; the two ends of the first upper sling are respectively hung on the upper lifting eyes of the lifting beams at the second and third top ends, and the middle part is hung on a hook claw of the crane main hook; the two ends of the second upper sling are hung on the upper lifting eyes of the lifting beams at the top of the two auxiliary risers, and the middle part is hung on the other hook claw of the crane main hook, which can solve the problem of easy shaking of the center of gravity of the jacket.

[0004] However, the existing technology still has many defects: (1) Traditional lifting devices may have space limitations, resulting in a large distance between the floating crane main hook and the upper platform of the conductor frame, affecting construction efficiency and safety. (2) The existing lifting device may not be able to ensure the uneven force caused by the different torque slope capabilities of each distributed motor, affecting the driving stability of the vehicle. (3) The existing lifting device may have insufficient safety protection measures, such as overload protection, anti-fall devices, etc., resulting in safety hazards during the lifting process. (4) The existing lifting device may use materials with poor corrosion resistance, resulting in a short service life in the marine environment and high maintenance costs. (5) The existing lifting device may be complicated to operate and require a lot of manual intervention, affecting construction efficiency. (6) The existing lifting device may have low construction efficiency and cannot meet the rapid installation requirements of deep-sea wind turbine foundation construction. Utility Model Content

[0033] The utility model provides a device that can be used for lifting a three-tube suction-type jacket, which not only meets the bearing capacity during the lifting of the jacket, but also reduces the distance between the floating crane main hook and the upper platform of the jacket as much as possible. In addition, the four hanging rope pins in the device can balance the floating crane hook so that the force is evenly distributed. The triangular plane formed by the lower pins corresponds one to one with the three lifting ears on the upper platform of the jacket, which can ensure the safety of lifting during the construction process and improve work efficiency.

[0034] like Figure 1 、 Figure 2 as well as Figure 3 As shown, the utility model provides a lifting device for a large-tonnage three-tube suction jacket, the device comprising: two 1-upper beams, including 1a-first upper beam and 1b-second upper beam;

[0035] A 2-flange connecting beam connecting two 1-upper beams, including 2a-first flange connecting beam and 2b-second flange connecting beam;

[0036] Two 4-end beams provided on both sides symmetrically of the 2b-second flange connecting beam, including 4a-first end beam and 4b-second end beam;

[0037] 3-pins provided at both ends of the two 1-upper beams, both ends of the two 4-end beams and in the middle of a 2-flange connecting beam, including 3a-first pin, 3b-second pin, 3c-third pin and 3d-fourth pin provided at both ends of the two 1-upper beams; 3e-fifth pin, 3f-sixth pin provided at both ends of the two end beams and 3g-seventh pin provided in the middle of the 2-first flange connecting beam; and

[0039] The four hanging rope pins in this device can balance the floating crane hook so that it is evenly stressed. The triangular plane formed by the lower pins corresponds one-to-one with the three lifting ears on the upper platform of the jacket. This not only meets the bearing capacity during the jacket installation, but also minimizes the distance between the floating crane main hook and the upper platform.

[0040] Furthermore, the plane formed by the two 1-upper beams and the two 2-flange connecting beams being fixedly connected is parallel to the top platform of the three-tube suction jacket.

[0041] Furthermore, the two ends of the two 1-upper beams are each provided with a hanging rope 3-pin shaft which can be connected to the four main hooks of the floating crane through a sling.

[0042] Furthermore, the hanging rope points provided on the 2-flange connecting beam and the hanging rope 3-pin shafts provided on the lower parts of the two 4-end beams form an equilateral triangle in the same plane.

[0043] Furthermore, the present invention can also add a quick lock or slot-type connection structure based on the existing bolt connection to achieve rapid assembly and disassembly. These quick connection structures can be designed to be reusable, facilitating the rapid replacement or adjustment of the components of the sling under different working conditions.

[0044] Furthermore, the present invention can incorporate pulleys or hydraulic adjustment devices at the pins to adjust the position and angle of the spreader. These adjustment systems can automatically adjust the position and angle of the spreader based on the position and posture of the jacket during the lifting process, ensuring stable and safe lifting.

[0045] Furthermore, the present invention integrates force sensors, displacement sensors, and temperature sensors at key locations on the spreader to monitor the spreader's stress state, displacement, and temperature changes in real time. This sensor data can be wirelessly transmitted to a ground control center in real time, providing real-time data support for construction and ensuring the safety of the lifting process.

[0046] Furthermore, the present invention can also develop an intelligent control system that uses sensor data and pre-set programs to realize the automated operation of the hoist. The intelligent control system can automatically adjust the hoisting position and hoisting force, further improving construction efficiency and safety.

[0047] Furthermore, the present invention can also select materials with stronger corrosion resistance, such as stainless steel or high-strength aluminum alloy, for the manufacture of the spreader. These materials have good corrosion resistance and can be used in marine environments for a long time, reducing the impact on the environment.

[0048] Furthermore, the present invention utilizes recyclable materials and a modular design in the spreader design, facilitating disassembly and reuse. The use of recyclable materials reduces environmental impact, while the modular design improves the spreader's maintainability and replaceability, extending its service life.

[0049] Furthermore, the present invention can also add safety protection measures to the spreader design, such as overload protection and anti-fall devices. The overload protection can automatically cut off the power supply when the spreader exceeds the rated load, preventing damage to the spreader; the anti-fall device can quickly deploy in the event of an accidental fall of the spreader, preventing casualties and equipment damage.
