LIFTING MECHANISM AND LIFTING APPARATUS USING LIFTING MECHANISM

摘要

The present invention discloses a lifting mechanism mounted on a lifting device, wherein the lifting device comprises a carrying unit. The lifting mechanism is disposed under the carrying unit, and comprises a driving assembly and a lifting assembly. The driving assembly comprises an axle fixing part, a drive wheel and a power source, and the lifting assembly comprises a screw nut and a screw rod. An upper end of the screw rod is fixedly connected to the carrying unit. When the lifting mechanism is traveling, each drive wheel is in contact with a base surface and moves the lifting device on the base surface; and when lifting, each drive wheel rotates on the base surface to drive the screw nut to rotate about a vertical axis relative to the carrying unit, to drive the screw rod to lift the carrying unit along the vertical direction.
