Description

Technical Field

[0001] This utility model relates to the technical field of turning gear tooling for wind turbine generator sets, and in particular to a universal electric turning gear tooling for wind turbine generator sets. Background Technology

[0002] Currently, most wind turbine generator turning fixtures are manual or mechanical. Since the fixture mainly uses a turning handle to drive the turning fixture gear, and the turning fixture gear meshes with the external teeth of the high-speed shaft brake disc for turning, due to the influence of load, it is difficult to unify the parameters such as the type, size, and tooth pitch of the brake disc for different models. Therefore, usually one type of turning fixture can only be used for one type of turbine, which is costly, has low turning efficiency, and poses safety hazards. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a universal electric turning wheel tooling for wind turbine generator sets, which can effectively solve the problems of poor universality, high cost, low turning efficiency and safety hazards of the current turning wheel tooling.

[0004] The objective of this utility model can be achieved by adopting the following technical solutions:

[0005] A universal electric turning gear fixture for wind turbine generator sets includes a mounting base, a reducer mounting assembly, a cross joint, a turning flange, a reducer, and a motor. One end of the mounting base is mounted on the gearbox of the wind turbine generator set and located next to the high-speed shaft of the wind turbine generator set. The other end of the mounting base has two first elongated holes for connecting to the reducer mounting assembly. The first elongated holes extend along the height direction of the mounting base. The other end of the mounting base is perpendicularly connected to one end of the reducer mounting assembly through the two first elongated holes. The other end of the reducer mounting assembly is used to mount the reducer. The output shaft of the motor is connected to the input shaft of the reducer. The output shaft of the reducer is connected to the turning flange through the cross joint. The turning flange is connected to the high-speed shaft of the wind turbine generator set. The motor drives the reducer to rotate and drives the high-speed shaft to perform a turning motion.

[0006] Furthermore, the mounting base includes a base and an adjusting rod. The base is mounted on the gearbox of the wind turbine generator set. One end of the adjusting rod is vertically connected to the base, and the other end is provided with two first elongated holes for connecting to the gearbox mounting assembly. The first elongated holes extend along the height direction of the adjusting rod.

[0007] Furthermore, the mounting base has an overall L-shaped structure.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0011] This utility model's turning gear fixture adopts an innovative structure that directly connects to the high-speed shaft for turning operations. Since the interface dimensions of the high-speed shafts of different models are relatively uniform, it can be used for connecting high-speed shafts of multiple models, offering good versatility and meeting the turning requirements of 5-7 MW models. It eliminates the need for designing separate turning gear fixtures for each model, reducing costs. Simultaneously, the vertical and horizontal installation positions of the reducer can be adjusted via two sets of elongated holes, adapting to different installation conditions and broadening its applicability. Furthermore, this utility model's turning gear fixture is motor-controlled, eliminating the need for manual intervention in the turning process, making operation more efficient and safer.
