Pier body hoisting system with adjustable hoisting points

The invention provides a pier body hoisting system with an adjustable hoisting point, and relates to the field of bridge construction, the pier body hoisting system comprises a load-bearing subsystem, an adjusting subsystem and a hoisting connection subsystem, the load-bearing subsystem comprises a main beam, two sets of auxiliary beams and multiple sets of hoisting rods, the adjusting subsystem is used for adjusting the positions of the auxiliary beams and the hoisting rods, and a worker can hoist a pier body according to the position of the hoisting point of the pier body. The positions of the auxiliary beam and the suspender are rapidly adjusted through the adjusting subsystem, then the suspender is locked and hung on a positioning through hole of the auxiliary beam, and a floating crane hook lifts the hoisting device and a pier body through a steel wire rope-free ring and a connecting assembly; the hoisting operation is monitored through the steady state monitoring subsystem, analysis and early warning ar
