Movable wind generating set turning system and method

Abstract

The invention discloses a movable wind generating set turning system and method. The movable wind generating set turning system includes a fixing mechanism and a turning mechanism, the turning mechanism includes a motor and an output gear which is driven by the motor, and the output gear is used for being meshed with teeth of the outer edge of a main gear case brake disc; the fixing mechanism includes an adapter plate, a base platform and a base support, the adapter plate is used for being fixedly connected with a main gear case, and the base platform is fixedly connected with the adapter plate; and the upper portion of the base support is fixedly connected with the turning mechanism, the lower portion of the base support is movably fixed to the base platform thorough a guiding sliding rail, and the meshing or the separation of the output gear and the teeth of the outer edge of the brake disc can be realized through the location moving of the base support on the base platform. The movable wind generating set turning system further includes a limit switch for monitoring the distance of the output gear and the brake disc outer edge teeth. The invention further discloses a turning method. According to the movable wind generating set turning system and method, the meshing or the separation of a gear pair can be flexibly and conveniently realized thorough the arrangement of the guiding sliding rail, the turning system is not parallel with a wind power main engine by adopting the limit switch, and the safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a cranking system and a cranking method for a movable wind power generator. Background technique [0002] In the process of wind turbine installation and daily maintenance, especially blade replacement, pitch control cabinet maintenance, generator alignment and impeller locking pins in place, it is often necessary to rotate the impeller to a specific position for convenience. operate. At present, most domestic wind turbines can only complete this process by manually rotating the brake disc end of the coupling. However, with the increase of the fan impeller, the self-weight and moment of inertia of the entire impeller will also increase, making this traditional manual cranking more difficult, or even impossible, so the electric cranking system is used. Replacing manual cranking will be the mainstream direction of wind turbine development in the future. [0003] Mo...

Problems solved by technology

Such design often does not consider the communication protection between the cranking mechanism and the main control of the wind turbine. Therefore, when the cranking system is used in the wind farm, there may be misoperations, which may cause the main machine to start running and the cranking system to run concurrently, resulting in accident happened

[0004] It can be seen that the above-mentioned existing wind turbine turning system obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently.
