The self-climbing hoisting mechanism includes a lifting assembly, a lifting frame, a driving disc and a driving assembly. Rectangular grooves are provided at the four corners of the lifting frame, and vertical legs are provided in the rectangular grooves. Four driving motors are installed on the lifting frame, and the four driving motors are respectively provided corresponding to the four vertical legs. The driving motor is provided with a driving gear, and the driving gear is meshed with the rack, so that the lifting frame can be lifted and lowered along the vertical legs. The driving disc is arranged in the lifting frame, and a connecting rod is fixedly installed between the driving disc and the lifting frame. A bearing is installed at the axis of the driving disc, and a support shaft is installed in the bearing. A hanging beam is fixedly installed at the top of the support shaft. The driving assembly is installed on the driving disc and can drive the support shaft and the hanging beam to rotate. The lifting assembly comprises a hoist sports car and an electric hoist installed at the bottom of the hoist sports car. The hoist sports car is arranged on the hanging beam and can move axially along the hanging beam.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:
