The invention discloses a mechanical lifting platform with acceleration. The mechanical lifting platform comprises a platform body and a driving system, the table body is arranged above the driving system; the driving system comprises a motor speed reducer, a rigid coupling, a secondary speed reducer, a universal coupling and an acceleration and deceleration eccentric wheel assembly; the output end of the motor speed reducer is connected with two secondary speed reducers through two rigid couplings respectively, the two rigid couplings are longitudinally and symmetrically arranged, the output ends of the secondary speed reducers are connected with two acceleration and deceleration eccentric wheel assemblies through two universal couplings respectively, and the two universal couplings connected to the same secondary speed reducer are symmetrically arranged. The two acceleration and deceleration eccentric wheel assemblies connected to the same second-stage speed reducer are symmetrically arranged and are the same in rotating direction, and the eccentric wheel assemblies connected to different second-stage speed reducers are opposite in rotating direction. The acceleration and deceleration eccentric wheel assembly is fixedly connected with the table body. The lifting platform has the advantages that the problems of sudden start and stop, unstable lifting and large start and stop torque and static load torque of the lifting platform are solved, and the transmission efficiency and reliability of the lifting platform are improved.
