Description

Technical Field

[0001] This utility model relates to a wind power generation device, and more particularly to an adjustable wind turbine impeller assembly platform. Background Technology

[0002] During wind turbine installation, the wind turbine impeller needs to be assembled on-site. The wind turbine hub and blades are assembled using an on-site assembly platform. Due to limited space, especially in mountainous areas where the ground is uneven, the assembly platform is unstable and difficult to adjust, affecting the precise positioning of the impeller components. In addition, the existing platform cannot adapt to the assembly requirements of wind turbine impellers of different specifications, making it inconvenient for operators during the assembly process, seriously affecting assembly efficiency and quality, and increasing the cost of subsequent commissioning and maintenance. Therefore, there is an urgent need to develop a new type of wind turbine impeller assembly platform to solve the above technical problems. Summary of the Invention

[0003] This invention provides an adjustable impeller assembly platform that can precisely assemble wind turbine blades of various specifications.

[0004] This utility model solves the above technical problems through the following technical solution:

[0005] An adjustable impeller assembly platform includes a circular platform, a cross-shaped sleeve, and an anti-slip base. Hydraulic liftable legs are mounted on the anti-slip base. The top ends of the hydraulic liftable legs are hinged to a horizontal cantilever via hinges, forming an inverted L-shaped support leg mechanism. The outer end of the horizontal cantilever is movably inserted into a slot of the cross-shaped sleeve. Four inverted L-shaped support leg mechanisms movably cooperate with the cross-shaped sleeve to form a cross-leg type support. A positioning connecting block is provided on the top surface of the cross-leg type support, and a circular platform is mounted on the positioning connecting block.

[0006] A positioning connecting block embedding groove is provided on the bottom surface of the circular platform, and the circular platform is snapped onto the positioning connecting block by the positioning connecting block embedding groove.

[0007] Locating pin holes and a level are respectively provided on the top surface of the circular platform; after the impeller hub is placed on the circular platform, the blades are assembled.

[0008] This utility model has a stable structure and is easy to assemble on site, which improves the accuracy and efficiency of wind turbine impeller assembly and reduces labor intensity and production costs. Attached Figure Description

[0012] The present invention will now be described in detail with reference to the accompanying drawings:

[0013] An adjustable impeller assembly platform includes a circular platform 7, a cross-shaped sleeve 5, and an anti-slip base 1. A hydraulically adjustable support leg 2 is mounted on the anti-slip base 1. The top of the hydraulically adjustable support leg 2 is hinged to a horizontal cantilever 4 via a hinge 3, forming an inverted L-shaped support leg mechanism. The outer end of the horizontal cantilever 4 is movably inserted into a slot in the cross-shaped sleeve 5. The hinge of the horizontal cantilever 4 to the hydraulically adjustable support leg 2 increases the flexibility of adjusting the level of the circular platform 7 and reduces the difficulty of leveling using the hydraulically adjustable support leg 2. Four inverted L-shaped support legs and the cross-shaped sleeve 5 movably cooperate to form a cross-leg type support. This combined support makes it easier to flexibly adjust its position according to the site terrain and facilitates relocation and transportation. A positioning connecting block 6 is provided on the top surface of the cross-leg type support, and the circular platform 7 is mounted on the positioning connecting block 6, achieving stability of the circular platform 7.

[0014] A positioning connecting block embedding groove is provided on the bottom surface of the circular platform 7, and the circular platform 7 is snapped onto the positioning connecting block 6 through the positioning connecting block embedding groove.

[0015] Positioning pin holes 8 and a level 9 are respectively provided on the top surface of the circular platform 7; after the impeller hub 10 is placed on the circular platform 7, the blades 11 are assembled; positioning pins are inserted into the positioning pin holes 8 to position the impeller hub 10, thereby improving the installation accuracy of the blades 11.
