Compare in large-tonnage hoist needs experienced personnel to operate for transport after large-tonnage hoist aligns with the load and lead to the construction cycle length, the easy operation of this application handling frock makes the construction cycle also corresponding shorten.

In some embodiments, the connection frames include a first connection frame 91 of the auxiliary power unit 23 and a second connection frame 92 of the fixing frame 85. This facilitates the assembly of the auxiliary power unit 23 and the driving of the wire 37.

Fig. 12 is a schematic structural view illustrating an embodiment of the handling tool 20 of the present application applied to a cabin.

With reference to fig. 11 and 12, the following description will be made by taking a transformer 17 as an example of a large-sized component: the transformer 17 is mounted at the hatch opening in the nacelle 13. The hatch opening is provided with a detachable supporting plate. The transformer 17 is placed on the support plate when it is normally operated. When the transformer 17 needs to be replaced, the mounting position of the hoisting tool 20 is selected in the cabin 13, and the position can effectively utilize the reserved space of the cabin 13 to avoid other components. Then, the hoisting tool 20 is assembled in the nacelle 13, and is connected with the transformer 17 through the hoisting part 29, and the supporting plate is pulled away, so that the transformer 17 can be lowered to the ground from the hatch opening for replacement. Then, the flexible cable 37 is unreeled through the reel 36, the flexible cable 37 is driven by friction of the first friction wheel 41 and the second friction wheel 42 and is connected with the movable pulley assembly 28, so that the movable pulley assembly 28 descends downwards to drive the transformer 17 to descend downwards, and after the transformer 17 reaches the ground, the transformer 17 and the hoisting tool 20 are disassembled to replace a new transformer 17. Finally, after the new transformer 17 is connected with the lifting tool 20, the flexible cable 37 is wound through the winding drum 36, the flexible cable 37 is driven by friction of the first friction wheel 41 and the second friction wheel 42 and is connected with the movable pulley assembly 28, so that the movable pulley assembly 28 is lifted upwards to drive the new transformer 17 to be lifted upwards, and after the new transformer 17 reaches the cabin 13, the new transformer 17 and the lifting tool 20 are disassembled to finish the replacement of the transformer 17.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
