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.

    本申请涉及作业机械领域,公开了一种提升机构和作业机械,其中,提升机构包括:旋转动力装置;旋转减速装置,由旋转动力装置驱动且设有减速旋转输出端;和提升卷筒装置,包括筒壳、同轴设置在筒壳内的筒轴以及套设在筒轴与筒壳之间的连接套,连接套与筒壳相互固定,连接套与筒轴形成花键配合,筒轴的一端与减速旋转输出端形成可拆卸的花键配合。本申请中的旋转减速装置和提升卷筒装置均能够在保持结构整体性的情况下实现快速拆装,可降低筒壳的加工精度要求,可避免旋转减速装置出现渗油、漏油,可完全省去旋转减速装置现场安装调试的时间,可节省筒轴的用料,还能降低提升卷筒装置的制造和装配难度。
