The invention relates to the field of mechanical equipment, in particular to a lifting platform which comprises pedals, lifting devices and a driving device, the lifting devices are symmetrically installed on the two sides of the driving device, the pedals are arranged at the tops of the lifting devices, and each lifting device comprises a plurality of supporting frames, a fixed pulley, a screw, a transmission chain and a steel wire rope. The transmission chain is connected with the bottom of the screw in a meshed mode, the supporting frames are connected through limiting blocks in a sliding mode, the two ends of the steel wire rope are connected with the two supporting frames respectively, a lifting structure is arranged in the screw in a sleeved mode, and the lifting structure is fixedly connected with the supporting frames. The transmission chain drives the screw to rotate to lift the lifting structure step by step, the screw and the steel wire rope are combined, the screw is driven by the transmission chain to rotate to lift, the driving device is arranged at the bottom to lower the gravity center of the equipment, the transmission assembly is designed in a hidden mode to avoid damage, and parts are connected in a sleeving and pin connection mode. And the reliability of equipment is improved.
