Description

Technical Field

[0001] This utility model relates to a special lifting tool for integral mixed tower components, specifically a special lifting tool for lifting integral mixed tower components of different diameters, belonging to the field of wind power mixed tower engineering machinery and equipment. Background Technology

[0002] The rapid and high-quality development of modern wind power relies heavily on high-standard integrated hybrid tower components. A complete wind turbine hybrid tower, from ground to top, requires several integrated hybrid tower components of different diameters to be vertically spliced ​​together. These components need to be hoisted during production and transportation. Traditional hoisting tools simply use steel wire ropes, with one end of several ropes attached to the crane hook and the other end to the lifting ring of the integrated hybrid tower component. During hoisting, the steel wire ropes between the crane hook and the lifting ring of the integrated hybrid tower component are at an angle, resulting in a large inward component force during hoisting. If the wire ropes are of varying lengths, the inward force generated during hoisting will differ. Furthermore, even using wire ropes of the same length, the inward force generated during hoisting of monolithic hybrid tower components of different diameters will vary due to the different angles of the wire ropes. This can cause cracks to form on the top of the monolithic hybrid tower component during hoisting, a quality problem that is irreparable and necessitates scrapping, resulting in significant economic losses. This also fails to meet the substantial demand for hybrid tower wind power and severely hinders the rapid development of hybrid tower wind power construction.

[0003] To overcome the serious defects of the traditional method of directly hoisting integrated tower components with wire ropes, a special lifting device for integrated tower components has been invented: it consists of a main lifting beam 1, a secondary lifting beam 2, a main hook seat 3, a secondary hook seat 4, a lifting beam support plate 5, and a main and secondary lifting beam connecting seat 6; it is located between the crane hook and the wire rope. This lifting device changes the oblique lifting of the wire rope to vertical lifting of two sections of wire rope, fundamentally eliminating the inward component force generated by the traditional direct lifting with wire ropes, thereby eliminating cracks in the integrated tower components, ensuring product quality, improving production efficiency, and reducing costs.
