Prefabricated part hoisting and mounting auxiliary device

The utility model discloses a prefabricated part hoisting and mounting auxiliary device, which relates to the technical field of prefabricated part mounting, and comprises a hoisting system and a positioning system, the hoisting system comprises a lifting hook connecting piece, a telescopic balance rod connected with the lifting hook connecting piece and clamping components arranged at two ends of the telescopic balance rod and matched with a prefabricated part, the positioning system is arranged on the lifting hook connecting piece and used for adjusting the gradient of the telescopic balance rod. According to the utility model, the hoisting and mounting of the prefabricated part are improved from the traditional mode that the prefabricated part is firstly hoisted by an instrument and a hoisting belt in a matched manner and then the gradient is manually adjusted after the prefabricated part falls to the ground to the mode that the prefabricated part is directly adjusted to the designed gradient in the hoisti
