The invention relates to the field of operation machinery, and discloses a lifting mechanism and operation machinery. The rotary speed reduction device is driven by the rotary power device and is provided with a speed reduction rotary output end; the lifting drum device comprises a drum shell, a drum shaft coaxially arranged in the drum shell and a connecting sleeve arranged between the drum shaft and the drum shell in a sleeving mode, the connecting sleeve and the drum shell are mutually fixed, the connecting sleeve and the drum shaft are in spline fit, and one end of the drum shaft and the speed reduction rotation output end are in detachable spline fit. The rotary speed reduction device and the lifting drum device can be rapidly disassembled and assembled under the condition that structural integrity is kept, the requirement for machining precision of the drum shell can be lowered, oil leakage and oil leakage of the rotary speed reduction device can be avoided, the time for on-site installation and debugging of the rotary speed reduction device can be completely saved, materials of a drum shaft can be saved, and the production cost is reduced. And the manufacturing and assembling difficulty of the lifting drum device can be reduced.
