Abstract

The invention discloses a generator rotor hoisting air gap monitoring and protecting device. The device comprises a protecting device for collision sensing feedback of a rotor; a monitoring communication module which is used for receiving and processing feedback information of the protection device and sending an instruction to a report warning module; the report warning module which is used for receiving an instruction of the monitoring communication module and giving an alarm; a distance measuring module which is used for measuring a distance between the rotor and the bottom of the pit; a feedback display module which is used for receiving and processing feedback information and simulating and displaying the hoisting process and state of the rotor through a 3D graph; and a power supply guarantee module used for providing power. The protection device achieves protection and monitoring in a limited gap between a rotor and a stator, through cooperation of all modules, the number of used workers is greatly reduced, equipment protection is simple, safe and effective, hoisting monitoring covers all parts without hidden danger, equipment extrusion and collision alarm is timely, normal position operation is visual and visual, the hoisting process is synchronously displayed, and the walking bottom of the hoisting part can be monitored; safety of personnel and equipment is ensured, and hoisting is simple and quick.

Description

Technical field [0001] The present invention relates to the field of generator rotor hoisting techniques, and more particularly, the present invention relates to generator rotor hoisting air gap monitoring and protection devices. Background technique [0002] At present, the hydropower station vertical hydropower unit is mainly used in the installation and maintenance of the generator rotor, and the electric power (including the world's largest) generator rotor is between tens of tons and 2300 tons, while generator rotor and stator The air gap is only 42mm, and the difficulty of hoisting is likely to know. In order to ensure the safety of the hoisting process, damage to the rotor, the stator is damaged. The current taken protection is the hanging operation of the annular artificial continuous box with whistle command alarm. This kind of lifting work is federate, the time is expensive, the working efficiency is low, and the safety risks are large, and it is a big problem that cont...
