The invention relates to an engine room crane of a wind driven generator. The engine room crane of the wind driven generator comprises a traveling crane frame and an electric hoist; the traveling crane frame is provided with an electric hoist guide rail, the extending direction of the electric hoist guide rail is taken as a left-right direction, and the electric hoist can be arranged on the electric hoist guide rail in a left-right moving manner; the electric hoist comprises a hoist traveling frame, a speed reduction motor, a lifting chain and a chain collecting box; the hoist traveling frameis provided with hoist traveling wheels, and the hoist traveling wheels are arranged at left and right intervals; the speed reduction motor is fixed on the hoist traveling frame, and the axis of the speed reduction motor extends along the left direction and the right direction; the electric hoist further comprises a chain collecting box support, and the chain collecting box is hung on the chain collecting box support; the chain collecting box support is located on one side in the left-right direction of the hoist traveling frame and is used for balancing the weight distribution in the left-right direction of the electric hoist to balance the bearing of the hoist traveling wheels in the left-right direction, so that the deflection degree of the electric hoist in the engine room crane operation process is reduced, and the safety of the wind generating set in maintenance operation is improved.
本发明涉及一种风力发电机的机舱行车。所述风力发电机的机舱行车包括行车架和电动葫芦;行车架,其上设有电动葫芦导轨,以电动葫芦导轨的延伸方向为左右方向,电动葫芦可左右移动地设置在电动葫芦导轨上;电动葫芦包括葫芦行走架、减速电机、升降链条和集链箱;葫芦行走架,其上设有葫芦行走轮,葫芦行走轮左右间隔布置;减速电机固定在葫芦行走架上,其轴线沿左右方向延伸;电动葫芦还包括集链箱支架,集链箱吊挂在集链箱支架上;集链箱支架位于葫芦行走架的左右方向一侧,用于平衡电动葫芦左右方向的重量分布以平衡左右方向各葫芦行走轮的承重,从而降低电动葫芦在机舱行车作业过程中的偏摆程度,提高风力发电机组维护作业时的安全性。
