The invention discloses an auxiliary device for replacing a high-altitude frequency converter of a wind turbine generator, and the auxiliary device comprises a fixed part which comprises a moving platform, a rotating platform arranged below the moving platform, mounting brackets arranged on the two sides of the upper part of the rotating platform, a lifting frame arranged between the mounting brackets, and a hoisting frame arranged above the lifting frame; the hoisting component comprises a lifting assembly arranged above the hoisting frame, transmission assemblies arranged on the two sides of the hoisting frame, a rotating assembly arranged above the transmission assemblies and a winding assembly arranged at one end of the rotating assembly; wherein the transmission assembly is arranged in the mounting bracket, and the lifting assembly is fixedly connected with the lifting frame; the steel wire rope slides between the winding assemblies through the clamping plates, under the condition that the steel wire rope is suddenly broken and the lifting frame suddenly descends, the steel wire rope is wound on the outer side of a winding arc plate through the winding assemblies through cooperation of the transmission assembly, the rotating assembly and the winding assemblies, and therefore the steel wire rope is fixed; therefore, the frequency converter hoisted above the hoisting frame does not continue to descend, and the purpose of protecting the frequency converter is achieved.
本发明公开了一种风电机组高处变频器更换辅助装置,包括固定部件,其包括移动平台、设于所述移动平台下方的转动平台、设于所述转动平台上方两侧的安装支架、设于所述安装支架之间的提升架,以及设于所述提升架上方的吊装架;吊装部件,其包括设于所述提升架上方的升降组件、设于所述提升架两侧的传动组件、设于所述传动组件上方的转动组件,以及设于所述转动组件一端的绕卷组件;其中,所述传动组件设于安装支架的内部,所述升降组件与提升架固定连接;通过夹板使得钢丝绳滑动在绕卷组件之间,在钢丝绳突然崩断的情况下,提升架突然下降,会通过传动组件、转动组件以及绕卷组件的配合,从而使得绕卷组件将钢丝绳缠绕在绕卷弧板的外侧,从而使得钢丝绳固定住,从而使得吊装在提升架上方的变频器不会再继续下降,从而达到保护变频器的目的。
