导向构件53设于支撑结构2中，且导向构件53由支撑结构2的第一端延伸至支撑结构2的第二端，即导向构件53由塔架1延伸至风机3，从而将位于塔架1处的待转运部件9转运至风机3。
牵引构件51及从动构件52均与导向构件53相接，牵引构件51牵引从动构件52沿导向构件53往复移动。通过设置导向构件53，能保证牵引构件51与从动构件52均沿导向构件53移动，以减少牵引构件51牵引从动构件52移动的过程中，从动构件52由于受力不均匀而偏移的情况。

在第一转运装置5由支撑结构2的第二端向支撑结构2的第一端移动的过程中，首先，牵引构件51通过第一定位构件54与导向构件53定位，伸缩驱动构件56驱动从动构件52向支撑结构2的第一端移动预定距离，然后，从动构件52通过第二定位构件55与导向构件53定位，牵引构件51与导向构件53之间的定位解除，伸缩驱动构件56驱动牵引构件51向支撑结构2的第一端移动，伸缩驱动构件56如此伸缩循环，直至牵引构件51及从动构件52到达支撑结构2的第一端。
通过伸缩驱动构件56，使牵引构件51与从动构件52通过伸缩分段的方式在支撑结构2的第一端与支撑结构2的第二端之间移动，使牵引构件51与从动构件52之间始终保持较近的距离，不会出现由于二者距离过远而导致从动构件52和/或牵引构件51移动方向偏移的情况。

牵引构件51的嵌槽511与导轨嵌接后，使牵引构件51仅能沿导轨的延伸方向移动，而无法沿其他方向移动，从动构件52的嵌槽522与导轨嵌接后，使从动构件52仅能沿导轨的延伸方向移动，而无法沿其他方向移动。从而保证牵引构件51与从动构件52能沿着导轨往复移动而不易与导轨脱离。
如图2至图5所示，本申请实施例提供的风力发电机组，其中，导轨设有两条，两条导轨相互平行，牵引构件51及从动构件52分别形成有两个嵌槽，牵引构件51的两嵌槽511及从动构件52的两嵌槽522分别与两导轨嵌接。
