Description

Technical Field

[0001] The utility model relates to the technical field of assembling a yaw brake of a wind generator set, in particular to a universal tool used for assembling a yaw brake of a wind generator set. Background Art

[0002] Currently, there are a growing number of wind turbine models, each with its own distinct characteristics. During yaw brake assembly, a tooling system with a yaw brake tightening function is required to secure the yaw gear ring to the proper position. However, due to these differences between wind turbine models, this tooling is not universally applicable. Almost every yaw brake assembly tightening tooling system is only compatible with one wind turbine model, resulting in the production of numerous different types of tooling. After use, these tools sit idle in the material workshop, occupying storage resources, leading to significant resource waste and increased costs. Utility Model Content

The tightening installation of the yaw brake is achieved by screwing the tightening bolts.

[0006] Furthermore, the tightening platform includes a base plate and two steel plates, two long waist holes are symmetrically arranged on the base plate, and the two steel plates are symmetrically arranged on the base plate and located between the two long waist holes.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figure 1As shown, this embodiment provides a universal tooling for assembling the yaw brake of a wind turbine generator set, comprising two connecting plates 1, two tightening bolts 2 and a tightening platform 3. The two connecting plates 1 are symmetrically arranged on the base 5 of the wind turbine generator set and are located on the left and right sides of the yaw brake 4 to be tightened. Two long waist holes 303 are symmetrically arranged on the tightening platform 3. The two connecting plates 1 are connected to the tightening platform 3 through the two long waist holes 303. Two threaded holes 304 for installing the tightening bolts 2 are formed on the top of the tightening platform 3. The two tightening bolts 2 are respectively screwed into the two threaded holes 304, and their end faces are in contact with the yaw brake to be tightened. The tightening installation of the yaw brake is achieved by screwing the tightening bolts 2.

[0020] like Figure 2 As shown, the tightening platform 3 includes a base plate 301 and two steel plates 302. Two long waist holes 303 are symmetrically arranged on the base plate 301. The two steel plates 302 are symmetrically arranged on the base plate 301 and located between the two long waist holes 303. Each steel plate 302 is provided with a threaded hole 304 for installing the tightening bolt 2.

[0021] like Figure 3 As shown, one end of the connecting plate 1 is provided with a first through hole 101 for connecting to the machine base 5 , and the other end thereof is provided with two second through holes 102 for connecting to the tightening platform 3 .

[0022] When installing the yaw brake, it must be pressed against the yaw ring gear 6 to prevent radial movement. The yaw brakes are generally evenly distributed on the machine base 5 along the circumference of the yaw ring gear. Before using this universal fixture, mounting holes (not shown) must be drilled into the yaw brake mounting surface of the machine base 5 for mounting the connecting plate 1. These mounting holes are located on the axis of symmetry between the yaw brake 4 to be tightened and the adjacent yaw brake. Installing the fixture eliminates the risk of interference between components, so there is one mounting hole on each side of the yaw brake, and these two holes are symmetrical about the yaw brake's axis of symmetry.

[0023] In addition, since the distance between the two mounting holes next to each yaw brake 4 to be tightened is related to factors such as the size of the yaw brake, the size of the pitch circle, and the number of distribution, and since there are certain differences between models, the yaw brake configurations are different. Therefore, this embodiment adapts to the changes in the distance between the mounting holes on the machine base 5 through the long waist hole 303, thereby achieving universality among different models.

[0024] When in use, first install the two connecting plates 1 on the machine base 5, then connect the connecting plates 1 to the tightening platform 3, and then screw in the tightening bolts 2. Generally, more than three sets of universal tooling are required to tighten the yaw brake at the same time, and the three sets of universal tooling are evenly distributed on the machine base 5 along the circumference, that is, three-point positioning, such as Figure 4Tighten the jacking bolt 2 and adjust the yaw brakes simultaneously so that the gap between each yaw brake and the yaw gear ring is less than a certain value. Then, secure the yaw brakes with fasteners and install the universal tooling to the positions of the other yaw brakes for jacking and installation.

[0025] In addition, the universal tooling of this embodiment can also be used to install and position the yaw gear ring. When installing the first few yaw brakes, the position of the yaw gear ring can be adjusted while tightening the brake using the universal tooling, and the distance between the yaw gear ring and a specific position of the machine base can be measured to ensure that it meets the requirements. Then, these yaw brakes can be fixed to complete the positioning installation of the yaw gear ring.

[0026] The above is only a preferred embodiment of the present utility model patent, but the protection scope of the present utility model patent is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present utility model patent based on the technical solution and the utility model patent concept of the present utility model patent, which falls within the protection scope of the present utility model patent.
