Description

Technical Field

[0001] The utility model relates to the technical field of hoisting of wind power hybrid towers, in particular to a hybrid tower lifting tool with multi-angle distributed lifting lugs. Background Art

[0002] When hoisting existing hybrid tower segments, the lifting lugs of the lifting tool adopt a single-direction distribution. During hoisting, the segments are unevenly stressed, which may cause quality problems such as deformation and edge chipping of the segments. At the same time, since the hybrid tower segments mainly include five-segment pieces (10 lifting points type) and four-segment pieces (8 lifting points type), the existing lifting tools have low hoisting applicability and cannot meet the hoisting requirements of these two types of segments at the same time. The lifting lugs of the lifting tool are extremely prone to bumping and wear during transportation and storage, and the safety of the lifting tool is poor. Therefore, it is urgent to design a hybrid tower lifting tool with multi-angle distributed lifting lugs to effectively solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hybrid tower lifting tool with multi-angle distributed lifting lugs, which has the advantages of simple structure, small volume, light weight, high applicability, high safety, preventing deformation and edge chipping of the segments during hoisting, preventing bumping and wear, etc.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A hybrid tower lifting tool with multi-angle distributed lifting lugs includes a lifting disc and a lifting lug group. At least two concentric lifting lug groups are arranged on the bottom surface of the lifting disc. Each lifting lug group includes a plurality of lifting lugs. The plurality of lifting lugs are evenly distributed along the circumference on the bottom surface of the lifting disc, and the distribution angle of the lifting lugs is determined according to the distribution angle of the lifting points of the hybrid tower segments. A ring beam is arranged between two adjacent lifting lug groups on the bottom surface of the lifting disc.

[0006] Further, a ring beam is arranged between two adjacent lifting lug groups on the bottom surface of the lifting disc, and the height of the ring beam is greater than the height of the lifting lug group.

[0007] Further, the ring beam is a circular cylindrical structure and is fixed to the bottom surface of the lifting disc by welding.

[0008] Further, main rib beams and two secondary rib beams are arranged on the top surface of the lifting disc, and the two secondary rib beams are arranged on both sides of the main rib beam.

[0009] Further, the main rib beam is a symmetric structure and is arranged along the radial direction of the lifting disc. It consists of a hump-shaped structure at the center and trapezoidal structures arranged on both sides of the hump-shaped structure.

[0010] Further, shackle holes are arranged on the hump-shaped structure of the main rib beam.

[0011] Further, the secondary rib beam is of a claw-shaped structure. The side surface of the secondary rib beam is connected to the side surface of the main rib beam by welding, and its bottom surface is connected to the top surface of the hanging plate by welding.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] 1. The lifting tool of the utility model adopts a multi-angle distributed hanger design, which can make the stress of each lifting point uniform when the segment is lifted, thus avoiding the deformation of the segment, improving the problems of chipping and compression of the segment, and improving the overall quality of the mixing tower.

[0014] 2. The lifting tool of the utility model adopts a design in which the ring beam is higher than the hanger, which can ensure that the hanger will not be knocked and damaged or deformed during transportation and storage. At the same time, it also plays the role of the annular stiffening rib of the lifting tool. The ring beam design not only extends the service life of the lifting tool, but also improves the load-bearing performance of the lifting tool.

[0015] 3. The overall volume of the lifting tool of the utility model is small and the weight is light, which can be adapted to more types of cranes, and at the same time reduces the consumption of its transportation cost and crane cost. BRIEF DESCRIPTION OF THE DRAWINGS
