[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 The present invention provides a ductile iron planetary carrier support structure for wind power equipment, comprising: a top cover 1 and a support frame 2.

[0020] Among them, such as Figures 1-3 As shown, a support frame 2 is fixedly connected to the bottom of the top cover 1. An adjustment plate 8 is provided inside the support frame 2. Both the support frame 2 and the adjustment plate 8 are provided with gear mounting hole groups. The gear mounting hole groups include three first through holes 4 that are equidistantly arranged on the bottom of the adjustment plate 8 and the support frame 2. A second through hole 5 is provided at the bottom center of the support frame 2. A third through hole 9 is provided at the bottom center of both the adjustment plate 8 and the top cover 1. Planetary gears can be installed inside the support frame 2. Each gear can be matched and installed through the first through hole 4, the second through hole 5 and the third through hole 9 and mesh with each other.

[0021] Furthermore, the inner diameter of the third through hole 9 matches that of the first through hole 4, and the inner diameter of the second through hole 5 is larger than that of the third through hole 9. The first through hole 4 and the third through hole 9 are the same size, which is beneficial for fixing and restricting the position of the rotation axis of the planetary gear. Since the inner diameter of the second through hole 5 is larger than that of the third through hole 9, the second through hole 5 is used to install the central sun gear or the main drive shaft.

[0022] In this embodiment, as Figures 1-4 As shown, a rod 12 is fixedly connected to the top of the adjusting plate 8. Multiple limiting blocks 13 are arranged at equal intervals on the outer wall of the rod 12. A circular groove 11 is provided on the top of the top cover 1. The inner wall of the circular groove 11 has at least three arc-shaped grooves 10 distributed at equal intervals around the circumference. Two arc-shaped protrusions 14 are symmetrically provided on the inner wall of the arc-shaped grooves 10. The rod 12 passes through the arc-shaped grooves 10, and the bottom of the limiting block 13 is attached to the top of the arc-shaped protrusion 14.

[0023] In use, the adjusting plate 8 can move up and down within the support frame 2. By rotating the rod 12, the adjusting plate 8 fixed therewith can rotate slightly within the support frame 2. The limiting block 13 on the outer wall of the rod 12 slides along the arc groove 10 in the circular groove 11 at the top of the top cover 1, and is constrained by the symmetrical arc protrusions 14 in the arc groove 10, thereby realizing the height adjustment of the adjusting plate 8 within the support frame 2.

[0024] Furthermore, refer to Figure 3 and Figure 4The circular groove 11 has a disc 15 inside. At least three L-shaped inserts 16 are distributed at equal intervals around the bottom of the disc 15. The shape of the L-shaped inserts 16 matches the shape of the arc groove 10. The inner wall of the circular groove 11 is threaded with an end cap 3. The L-shaped inserts 16 at the bottom of the disc 15 are inserted into the corresponding arc groove 10 to lock the current position of the limiting block 13. The end cap 3 is then threaded into the circular groove 11 to press and fix it.

[0025] like Figure 1 and Figure 4 As shown, the top of the end cap 3 has multiple rectangular grooves 7 evenly distributed around the circumference, and a hexagonal prism 6 is fixedly connected to the top of the end cap 3. The hexagonal prism 6 and the rectangular grooves 7 on the top of the end cap 3 provide tool operation interfaces, making it convenient to rotate the end cap 3.

[0026] It should be noted that the top cover 1, support frame 2 and adjusting plate 8 are all made of ductile iron. Ductile iron has good mechanical strength, impact resistance and corrosion resistance. Its application in the top cover 1, support frame 2 and adjusting plate 8 can improve the structural stability and durability of the whole machine.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, the adjusting plate 8 can move up and down within the support frame 2, and by rotating the rod 12, the adjusting plate 8 fixed therewith can rotate slightly within the support frame 2. The limiting block 13 on the outer wall of the rod 12 slides along the arc groove 10 in the circular groove 11 at the top of the top cover 1, and is constrained by the symmetrical arc protrusions 14 in the arc groove 10, so as to realize the height adjustment of the adjusting plate 8 within the support frame 2, which facilitates the installation of gears of different thicknesses or gear shafts of different lengths between the support frame 2 and the adjusting plate 8.

[0028] After the height of the adjusting plate 8 is adjusted within the support frame 2, the L-shaped insert 16 at the bottom of the disc 15 is inserted into the corresponding arc groove 10 to lock the current position of the limiting block 13. Then, the end cover 3 is threaded to the circular groove 11 to press and fix it. The hexagonal prism 6 or rectangular groove 7 at the top of the end cover 3 provides a tool operation interface for easy rotation of the end cover 3.

[0029] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
