The invention discloses an automatic connecting device for standard sections of a tower crane. An automatic nut pre-tightening device of the automatic connecting device comprises a fixed base, a sliding platform, a lifting platform, a nut tightening device, a telescopic sleeve, a sliding oil cylinder, a lifting oil cylinder and a control system. The fixed base is fixedly mounted on the jacking sleeve frame; the sliding platform is installed on the top of the fixed base in a sliding fit mode in the horizontal direction. The sliding oil cylinder is fixedly mounted at the bottom of the fixed base; the lifting platform is installed on the sliding platform in a sliding fit mode in the vertical direction. The lifting oil cylinder is fixedly mounted on the sliding platform; the two nut tightening devices are movably mounted on the lifting platform; one end of each nut tightening device is provided with a telescopic sleeve capable of stretching out and drawing back in the vertical direction. And the telescopic sleeve is used for dismounting and connecting the self-locking bolts of the two standard knots. According to the automatic connecting device, the labor intensity of workers can be reduced, the mounting efficiency is improved, and the falling risk of the workers in the construction process can be avoided.
