Description

Technical Field

[0001] The utility model relates to the technical field of steel strand pay-off equipment, in particular to a wind turbine mixing tower steel strand turntable which is convenient for disassembly, assembly and transportation. Background Art

[0002] The renewable energy wind power market is currently seeing increasingly larger installed units and taller turbines. Traditional steel towers are unable to meet these height requirements, making hybrid tower wind turbines the mainstream in low-wind-speed regions. After the hybrid towers are hoisted and installed, steel strands are required to anchor the concrete towers. To facilitate transportation and ensure standardized on-site usage, manufacturers bundle the strands into bundles of 10 strands before shipping to the construction site. Before use, cranes and manual labor are used to straighten and release internal forces. This process requires extensive mechanical effort and involves numerous personnel, making it prone to vibration and potentially causing injuries. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provide a wind turbine mixed tower steel strand turntable that is easy to disassemble, assemble and transport. The steel strands can be placed on the turntable as a whole, reducing the cost of machinery and personnel use and avoiding personal injury during the wire laying process.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:
