The invention provides a mechanical spiral lifting device which comprises a base and a lifting part, wherein a cylindrical containing space is formed in the base, and a screw thread is arranged on the inner wall of the base for defining the containing space; a rotatable rotation shaft driven bya transmission mechanism is arranged at the central position of the bottom of the base, and the lifting part is cylindrical and is telescopically arranged at the base; the rotation shaft extends into the lifting part and can drive the lifting part to rotate, and a screw thread matched with the screw thread on the inner wall of the base is arranged on the outer wall of the lifting part. The mechanical spiral lifting device realizes a lifting function through a mechanical transmission lifting structure. By a standardization and modularization design, the mechanical spiral lifting device can be used as a set of standardized and modularized lifting device to be applied to various lifting equipment, vehicles or machines. The mechanical spiral lifting structure can increase the lifting height and has a high lifting performance. As the mechanical spiral lifting structure is adopted, when multiple mechanical spiral lifting devices are jointly used, the synchronous lifting for objects can be realized, and the lifting stability is improved.
