<p>A dynamical synchronization hoisting device includes a lifting pallet, motors (11), reduction boxes, transmission shafts (1,2,3,4), transmission sprockets (12) and chains (13), wherein at least three transmission shafts (1,2,3,4) are positioned, each of which is provided with a motor (11), a brake mechanism and a cycloid reduction unit (9). The output end of the cycloid reduction unit (9) located at one end of each transmission shaft (1,2,3,4) is connected with a synchronization mechanism, and the other end of each transmission shaft (1,2,3,4) is connected with transmission sprockets (12) and chains (13) through a reducer (14). Each transmission shaft (1,2,3,4) further includes shaft couplings (10) or universal joints (7) and bearing supports (8). The hoisting device is applicable for lifting pallet or turntable of stereo-parking device with advantage of smooth operation.</p> |
