[0002] The wind power bearing cage belongs to a large-diameter, thin-walled, special-shaped ring part. During transportation, the wind power bearing cage is prone to deformation. Now, there is an urgent need for a packaging structure part for transporting the wind power bearing cage and preventing the wind power bearing cage from deforming. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a packaging structure part for a wind power bearing cage that can be used for transporting the wind power bearing cage and prevent the wind power bearing cage from deforming.

[0004] To solve the above problems, the technical solution adopted by the utility model is as follows: A packaging structure part for a wind power bearing cage, characterized in that it includes: several bottom blocks, several stacking blocks, several screw rods, and several nuts. The bottom of the bottom block is flatly arranged, and a stepped surface that can fit with the inner ring of the cage is arranged on the outer end surface of the bottom block. A stepped surface that can fit with the inner ring of the cage is also arranged on the outer end surface of the stacking block. The stepped surface successively includes an upper positioning step for the top of the cage to abut against, an inclined support surface for the middle part of the cage to abut against, and a lower positioning step for the bottom of the cage to abut against. A stacking notch in the shape of a right trapezoid is arranged at the bottom of the stacking block, and the inclined waist of the stacking notch is close to the outer end surface of the stacking block. Through holes vertically arranged for the screw rods to pass through are arranged on both the bottom block and the stacking block. A counterbore for accommodating the nut is arranged at the bottom of the through hole on the bottom block. The stacking block can be stacked on the bottom block through the stacking notch, and the stacking blocks can also be stacked on each other through the stacking notch. When the stacking blocks are stacked on each other or when the stacking block is stacked on the bottom block, the through holes on both of them can be vertically aligned and communicated. By arranging several bottom blocks in a ring shape and making their outer end surfaces respectively fit with the inner ring of the cage, the cage can be supported. One stacking block can be stacked on each bottom block, and one stacking block can also be stacked on each stacking block. After the outer end surfaces of the stacking blocks at the same height respectively fit with the inner ring of the cage, the cage can be supported, so that each cage can be stacked on the bottom block. The screw rod can pass through the through holes of the bottom block and each stacking block stacked together, and then the nuts are respectively screwed tightly at both ends of the screw rod to fix the stacked bottom blocks and stacking blocks together.

[0005] Further, in the aforementioned packaging structure part for a wind power bearing cage, the bottom block and the stacking block are both wooden blocks; the bottom block and the stacking block can also be nylon blocks.

[0006] Further, in the aforementioned packaging structure part for a wind power bearing cage, the inclination angle of the inclined waist of the stacking notch is the same as the inclination angle of the inclined support surface.

[0007] Furthermore, for the aforesaid packaging structural member of the wind power bearing cage, when the bottom block and the stacked blocks are stacked, they can be vertically aligned both front and back and left and right.

[0008] The advantages of the present utility model are as follows: the aforesaid packaging structural member can tightly expand the cage so that the cage is not easily deformed during transportation, and can stack and package each cage, thereby greatly reducing the packaging volume.

[0012] The present utility model will be further described in detail below in conjunction with specific embodiments and the drawings.

[0013] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the packing structure of the wind power bearing cage includes: several bottom blocks 1, several stacking blocks 2, several screw rods, and several nuts. The bottom of the bottom block 1 is flatly arranged, and a stepped surface that can fit with the inner ring of the cage 6 is arranged on the outer end surface of the bottom block 1. A stepped surface that can fit with the inner ring of the cage 6 is also arranged on the outer end surface of the stacking block 2. The stepped surface successively includes an upper positioning step 3 for the top of the cage 6 to abut against, an inclined support surface 4 for the middle part of the cage 6 to abut against, and a lower positioning step 5 for the bottom of the cage 6 to abut against. A stacking notch 7 in the shape of a right trapezoid is arranged at the bottom of the stacking block 2. The inclined waist of the stacking notch 7 is close to the outer end surface of the stacking block 2. Through holes 8 vertically arranged for the screw rods to pass through are arranged on both the bottom block 1 and the stacking block 2. A counterbore 9 for accommodating the nut is arranged at the bottom of the through hole 8 on the bottom block 1. The stacking block 2 can be stacked on the bottom block 1 through the stacking notch 7, and the stacking block 2 can also be stacked with other stacking blocks 2 through the stacking notch 7. When the stacking block 2 is stacked with other stacking blocks 2 or when the stacking block 2 is stacked with the bottom block 1, the through holes 8 on both of them can be vertically aligned and communicated. By arranging several bottom blocks 1 in a circular pattern and making their outer end surfaces respectively fit with the inner ring of the cage 6, the cage 6 can be supported. One stacking block 2 can be stacked on each bottom block 1, and one stacking block 2 can also be stacked on each stacking block 2. After the outer end surfaces of the stacking blocks 2 at the same height respectively fit with the inner ring of the cage 6, the cage 6 can be supported, so that each cage 6 can be stacked on the bottom block 1. The screw rod can pass through the through holes 8 on the stacked bottom blocks 1 and each stacking block 2, and then the nuts are screwed on both ends of the screw rod to fix the stacked bottom blocks 1 and stacking blocks 2 together. When transporting the ring parts, the bottom block 1 will be fixed. After setting the stacking notch 7, when stacking, the outer end of the stacking block 2 can better block the outside of the cage 6, so that the cage 6 can be better positioned.

[0014] In this embodiment, both the bottom block 1 and the stacking block 2 are wooden blocks, and the wooden blocks are inexpensive. In practical applications, the bottom block 1 and the stacking block 2 can also be nylon blocks.

[0015] The inclination angle of the inclined waist of the stacking notch 7 is the same as the inclination angle of the inclined support surface 4. When the bottom block and the stacking block are stacked,

[0016] they can be vertically aligned in the front, back, left, and right directions.
