Problems solved by technology

Although this method is feasible, the safety is not good, because when this method is turned over, the operator has to be under the stator or climb on the stator to perform the hook hook operation. When the tool breaks, a major accident will occur
At the same time, the turning of the crane requires the installation and removal of the turning protection coil tooling, resulting in a decrease in efficiency
In addition, the crane can only be turned over by 90° and 180°, but the stator cannot be turned over and locked at any angle for operation

Abstract

The invention discloses a turning process method and device for a stator in a large wind-driven generator thereof. The method comprises the following steps: installing a dummy shaft on the stator; clamping and fixing the stator with the dummy shaft on a supporting frame; installing and fixing the dummy shaft on the stator through a clamping device on the supporting frame; installing the supporting frame on a stand with a rotating device; driving the supporting frame to turn by utilizing the rotating device to realize the purpose of coaxially turning the stator, the dummy shaft and the supporting frame; and simultaneously, locking the supporting frame by utilizing a braking device to realize the purpose of stopping and fixing the stator, the dummy shaft and the supporting frame at arbitrary angle, wherein in turning and locking processes, the stator is not in direct contact with the supporting frame so that the stator can not collide with the supporting frame. By using the turning process method and device for the stator in the large wind-driven generator thereof of the invention, the stator can be turned to the arbitrary angle for operating in the turning process, can not collide with a coil in the turning process, is safe and reliable simultaneously, has no need of installing a turning protection coil tool and has high turning efficiency.

Description

technical field [0001] The invention relates to a process method and a device for turning over an electric motor stator, and specifically relates to a process method and a device for turning an inner stator of a large-scale wind power generator. Background technique [0002] The large outer rotor structure directly drives the wind turbine, and the stator is arranged inside the rotor, so the periphery of the stator is full of coils. Due to the large outer diameter of the stator (5 meters) and the weight of more than 20 tons, in the process of mass production, how to ensure safety when turning over, to ensure that the coil will not be damaged, and at the same time achieve fast and efficient turning is a problem that needs to be solved well. [0003] At present, using the dummy shaft installed in the middle of the inner stator, a large-tonnage double-hook crane is used for overturning. Although this method is feasible, the safety is not good, because when this method is turned...
