[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] like Figures 1 to 9 As shown, the present embodiment provides a positioning and adjustment device for the yaw gear ring of a wind turbine generator set, comprising a positioning block 1, a fixing bolt 2 and an adjusting bolt 3. The positioning block 1 is respectively processed with a positioning surface 102 for fitting with the cushion step 7 of the front machine base 5 of the wind turbine generator set and a guide surface 103 for guiding and installing the yaw gear ring 6. The left and right sides of the positioning block 1 are respectively fixed to the front machine base 5 of the wind turbine generator set by fixing bolts 2, so that the positioning surface 102 is tightly fitted with the cushion step 7. The yaw gear ring 6 is roughly positioned and installed by the guide surface 103. The adjusting bolt 3 is arranged at the center of the positioning block 1. The end of the adjusting bolt 3 is abutted against the inner circumferential surface 601 of the yaw gear ring 6. The yaw gear ring 6 is finely adjusted by rotating the adjusting bolt 3.

[0029] Specifically, the left and right sides of the positioning block 1 are respectively processed with first bolt holes, which are through-through from top to bottom and are used for installing the fixing bolt 2. Two symmetrical bosses 101 are formed on the left and right sides of the front side of the positioning block 1. A step is formed on each boss 101. The lower side of the step is a positioning surface 102 for fitting with the gasket step, and the upper side of the step is a guide surface 103 for guiding the installation of the yaw gear ring 6. A second bolt hole that is through-through from front to back is provided at the center of the positioning block 1 for installing the adjustment bolt 3. Furthermore, the top edge of the guide surface 103 is processed with a chamfer 104 for facilitating the installation of the yaw gear ring 6.

[0030] Specifically, a gasket 4 is provided between the positioning block 1 and the fixing bolt 2 .

[0031] In actual use, multiple positioning and adjusting devices can be provided as needed and evenly arranged along the circumference of the front base. This embodiment takes four as an example.

[0032] The method of using the positioning adjustment device of this embodiment is as follows:

[0033] 1. Fit the positioning surface of the positioning block tightly with the gasket step of the front base, and use the fixing bolts to install the positioning block on the front base. Install four sets in total and distribute them as evenly as possible;

[0034] 2. Screw the adjusting bolt into the second bolt hole of the positioning block. At this time, it should not exceed the guide surface and positioning surface of the positioning block;

[0035] 3. Lift the yaw gear ring and drop it into the positioning block. At this time, due to the guiding effect of the positioning block, the gear ring is in a rough positioning state;

[0036] 4. Measure the gap between the positioning block and the machined surface of the yaw gear ring (i.e. the inner circumference), and rotate the adjusting bolt to fine-tune the yaw gear ring as needed, so that the gap difference between the four positioning blocks and the machined surface of the yaw gear ring meets the technical requirements.

[0037] Embodiment 2:

[0038] This embodiment provides a mounting structure for a yaw gear ring of a wind turbine generator set, including the positioning and adjusting device for the yaw gear ring of a wind turbine generator set described in Embodiment 1.

[0039] The above is only a preferred embodiment of the utility model patent, but the protection scope of the utility model patent is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the utility model patent according to the technical solution of the utility model patent and its utility model patent concept, which are all within the protection scope of the utility model patent.
