Lifting tool for aligning and mounting acceleration cavity

The invention discloses a lifting tool for aligning and mounting an acceleration cavity. The lifting tool comprises a lifting frame and at least two first steel wire ropes and is characterized by further comprising two telescopic distance adjusting rods, wherein each telescopic distance adjusting rod is connected with two second steel wire ropes; each telescopic distance adjusting rod is connected to the lifting frame by the two second steel wire ropes corresponding to the telescopic distance adjusting rod; at least one first steel wire rope is connected with a rigging turnbuckle; the rigging turnbuckle and the corresponding first steel wire rope form a connection rope for connecting a crane lifting hook with the lifting frame; the rigging turnbuckle is used for changing the total length of the corresponding connection rope; each telescopic distance adjusting rod comprises a first folding rod and a second folding rod, the first folding rod and the second folding rod are in articulated connection with each other via a pin, the axis direction of the pin is located in a vertical direction, and the first folding rod and the second folding rod can rotate around the axis of the pin. Through the lifting tool, the labor intensity of an operator during aligning and mounting the acceleration cavity is reduced; the mounting efficiency is improved; and the severe secondary pollution in the mounting process is avoided.
