Chain collecting device of electric chain hoist of wind turbine generator

The invention relates to a chain collecting device of an electric chain hoist of a wind turbine generator. The chain collecting device comprises a shell assembly and a transmission chain mechanism. The shell assembly comprises a chain storage box shell and a chain inlet guide pipe; the chain inlet guide pipe comprises an inclined section, a bent section and a metal plate section which are connected in sequence; an included angle is formed between the inclined section and the horizontal direction, a chain of the electric chain hoist of the wind turbine generator obliquely enters the chain inlet guide pipe; the bent section is bent downwards to gradually reduce the included angle between the bending section and the vertical direction to 0 degree, and the metal plate section is of a box body structure and plays a role in improving the strength of the chain inlet guide pipe; in an initial state, the chain of the electric chain hoist of the wind turbine generator enters the bottom of the chain storage box shell th
