Technical Field

[0001] This invention belongs to the field of wind power equipment manufacturing and processing technology, specifically relating to a tooling for grinding the base of a wind turbine. Background Technology

[0002] The wind turbine base is a key structural component supporting the entire generator set, and its manufacturing precision and surface quality directly affect the installation accuracy and operational stability of the unit. During the manufacturing process, especially in the final fine grinding stage, multiple surfaces of the base need to be treated with high precision.

[0003] Currently, there are usually two methods for grinding the base of large wind turbines: one is to rely on multiple workers to work together to manually adjust and fix the base position. This method is labor-intensive, the positioning accuracy is difficult to guarantee, and there are safety hazards. The other method is to use large special clamps or robot clamping systems. The investment and subsequent operation and maintenance costs of such equipment are relatively high.

[0004] In view of this, the present invention provides a tooling for grinding the base of a wind turbine generator, so as to achieve low-cost processing of wind power generation equipment. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention relates to a tooling for grinding the base of a wind turbine generator, such as... Figures 1-6 As shown, it includes a mounting base 1, two sets of opposing brackets 2 that are detachably mounted on the mounting base 1 by fasteners, and a limiting support assembly 3 disposed on the brackets 2 for supporting the wind turbine base 5 or restricting its movement.

[0031] Specifically, the mounting base 1 consists of a base plate 11 made of a thick steel plate. Several mating grooves 12 are milled into the base plate 11, and positioning holes 13 are drilled in the mating grooves 12. The bracket 2 can be inserted into the mating grooves 12 and connected and fixed by bolts and positioning holes 13 for installation with the base plate 11. Four lifting lugs 4 are bolted to the connecting holes 14 at the four corners of the base plate 11 so that the entire fixture can be lifted and moved easily.

[0032] The support frame 2 consists of two sets of first supports 21, two sets of second supports 22, and one set of third supports 23, all of which are welded from structural steel. The first supports 21 are triangular in shape and are located at both ends of a line parallel to the axis of the wind turbine base 5. They are used to cooperate with the limiting support assembly 3 to form axial support for the wind turbine base 5. The second supports 22 have a more complex structure, including a support frame 221 located at the bottom of the wind turbine base 5, and a reinforcing frame 222 connected to the support frame 221 to enhance its radial support force.

[0033] The opposing surfaces of the support frame 221 and the reinforcing frame 222 are also connected by fasteners, including a mating opening 2211 on the support frame 221 that is adapted to the reinforcing frame 222. An assembly through hole is provided in the mating opening 2211 relative to the reinforcing frame 222, and a threaded hole is provided on the reinforcing frame 222 corresponding to the assembly through hole. A bolt is used to pass through the assembly through hole and then threadedly connected to the threaded hole to realize the combination between the support frame 221 and the reinforcing frame 222, so that the whole forms a stable "T" shape structure to provide effective support for the entire wind turbine base 5.

[0034] Two sets of third supports 23 are located at the radial ends of the wind turbine base 5, respectively, to restrict the radial movement of the wind turbine base 5.

[0035] Limiting support components 3 were installed at the critical stress points of bracket 2 and where the base needed to be restrained. For example... Figure 3 As shown, the component includes a threaded abutment bolt 31 and a threaded cap 32 connected to its bolt portion. The abutment bolt 31 is screwed into a corresponding threaded hole on the bracket 2. After the wind turbine base 5 is placed on the bracket 2, the operator uses a wrench to rotate the abutment bolt 31, so that its end or head is stably and vertically pressed against the unmachined surface of the wind turbine base 5, thereby achieving reliable fixation of the wind turbine base 5 and facilitating subsequent fine grinding operations. In this embodiment, the abutment bolt 31 is parallel to the axial direction of the first bracket 21, the second bracket 22, and the third bracket 23, respectively, to the axial direction of the wind turbine base 5, the direction perpendicular to the horizontal plane, and the radial direction of the wind turbine base 5.

[0036] In use, first, select a suitable bracket 2 according to the model and size of the wind turbine base 5 and accurately install it into the predetermined position on the mounting base 1. Then, use hoisting equipment to place the wind turbine base 5 stably on the bracket 2. Subsequently, adjust the abutment bolts 31 of each limiting support component 3 in sequence until they are vertically pressed against the non-machined surface of the wind turbine base 5, thus completely restraining it without any shaking. Finally, manual fine grinding can begin. After the work is completed, release the limiting support components 3, and the wind turbine base 5 can be lifted away.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
