Lifting-type maintenance platform system for tower frame of wind generation set

Abstract

The invention discloses a lifting-type maintenance platform system for a tower frame of a wind generation set. The tower frame is internally provided with a bottom platform and a top platform. An operation mechanism comprises a running rail fixedly arranged between the top platform and the bottom platform and a lifting platform which is connected with the running rail. A driving device comprises a driving motor and a driving steel wire rope. An output shaft of the driving motor is connected with the lifting platform through the driving steel wire rope. A monitoring device comprises a top positioning sensor and a bottom positioning sensor. The top positioning sensor and the bottom positioning sensor are both used for detecting a position of the lifting platform. A control unit comprises a main control module and a manual control module. The main control module is connected with the driving motor, the manual control module, the top positioning sensor and the bottom positioning sensor. The main control module is used for controlling start and stop of the driving motor. According to the lifting-type maintenance platform system for the tower frame of the wind generation set, the lifting-type maintenance platform system can be started and stopped at any positions according to demands of running and maintenance, automatic lifting can be achieved, the structure is simple and using is convenient.

Description

technical field [0001] The invention relates to the technical field of wind turbine maintenance, in particular to a wind turbine tower maintenance platform system. Background technique [0002] With the development and installation of a large number of high-power and ultra-low wind turbines, the height and diameter of wind turbine towers are also increasing and increasing, and the tower forms of wind turbines are also becoming more and more diverse, such as sliced ​​and concrete. The on-site operation and maintenance workload of the unit has increased significantly. Due to the high towers of high-power megawatt wind turbines, operation and maintenance personnel have to spend a lot of physical strength climbing to enter the nacelle and towers for maintenance work. Currently, the maintenance platforms of wind turbines are fixed at the original design height, and it is impossible to complete the tower alignment. Rack for maintenance at any height in a non-platform location. ...
