Technical Field

[0001] The utility model relates to the technical field of water turbine processing, in particular to a water turbine blade casting hoisting device. Background Art

[0002] The turbine blade is one of the key components of the turbine. Its shape and design directly affect the performance and efficiency of the turbine. The blade is usually made of special materials to withstand the impact of water flow and long-term wear. When the turbine is working, the blade rotates under the action of water flow, converting water energy into mechanical energy. Different types of turbines have different shapes and structures of blades. For example, the blades of mixed flow turbines are streamlined, while the blades of impulse turbines have unique shapes. High-quality blade design can improve the energy conversion efficiency of the turbine, ensure the stability and reliability of power generation, and play a vital role in the field of hydropower.

[0003] In the process of hoisting blade castings with the help of hoisting equipment, most of the existing hoisting equipment for turbine blade castings on the market use flexible parts such as cables or chains to bundle the blade castings, and the hoisting operation can be carried out after the bundling is completed. However, due to the large specifications of the blade castings, when bundling with the help of flexible parts such as cables, in order to find a suitable bundling position, the staff needs to gradually and repeatedly adjust the bundling parts, which results in too much time spent on the bundling link before the hoisting operation, making the entire hoisting operation quite time-consuming, and increasing the operation and time costs of the hoisting.
