Description

Technical Field

[0001] The present invention relates to a hoisting device for assembling a generator rotor, belonging to the technical field of hoisting for assembling a generator rotor. Background Art

[0002] During the assembly process of a generator rotor, due to its large volume and heavy weight, a hoisting device is usually used, and the hoisting device plays a crucial role.

[0003] Traditional hoisting devices for assembling generator rotors usually have a relatively simple structure and lack flexibility. Common hoisting devices mostly adopt fixed tracks and a single hoisting method, making it difficult to flexibly adjust according to different working scenarios and the specifications of generator rotors.

[0004] For example, the support structures of many existing devices lack adaptability to different working conditions and cannot conveniently adjust the height or position, resulting in difficulty in effectively arranging them in complex assembly sites. Moreover, in terms of driving displacement, existing devices can often only achieve movement in a relatively single direction, making it difficult to meet the requirement of precisely adjusting the hoisting position left and right, which affects the accuracy and efficiency of rotor assembly. Therefore, we propose a hoisting device for assembling a generator rotor. Summary of the Invention

[0005] In order to solve the problems existing in the prior art in the hoisting adsorption link, either the adsorption force of traditional devices is insufficient, easily leading to the risk of the rotor shaking or even falling off during hoisting; or the adsorption method is too single to adapt to generator rotors of different materials and shapes.

Finally, the motor three 331 rotates in reverse, the wire winding roller 332 retracts the wire traction rope 333, driving the strong magnetic attraction part 35 to rise, lifting the generator rotor, and completing the hoisting process. During the whole hoisting process, the stable connection component 37 ensures the stable connection between the wire traction rope 333 and the strong magnetic attraction part 35, improving the reliability of the hoisting.
