The invention discloses a crown block lifting device and method, and the crown block lifting device comprises a driving assembly which comprises a first rotating shaft and a second rotating shaft which are arranged in parallel at an interval and can rotate; the winding and unwinding assembly comprises a first wheel arranged on the first rotating shaft, a second wheel arranged on the second rotating shaft and a transmission belt, one end of the transmission belt is wound around the second wheel, and the other end of the transmission belt is connected with the lifting track after winding around the first wheel. The lifting/lowering force of the first wheel on the transmission belt is larger than the winding/releasing force of the second wheel on the transmission belt. The lifting stability and reliability of the lifting track and the crown block are effectively improved.

    本发明公开了一种天车升降装置和升降方法,天车升降装置包括驱动组件,包括间隔并行且可转动的第一转轴和第二转轴;收放组件,包括设在第一转轴上的第一轮、设在第二转轴上的第二轮以及一端卷绕在第二轮上且另一端绕经第一轮后与升降轨道连接的传动带,收放组件由驱动组件驱动时,传动带受到第一轮提升/下放的力大于传动带受到第二轮收卷/释放的力。本发明有效提高了升降轨道及天车升降的平稳性和可靠性。
