The invention provides a tower crane lifting device, and relates to the technical field of engineering machinery. The tower crane lifting device comprises a base, a sliding limiting mechanism is fixedly connected to the top of the base, a lifting joint is slidably connected to the center of the sliding limiting mechanism, and a lifting jacking mechanism corresponding to the lifting joint is arranged in the center of the base. A plurality of fixed-point locking mechanisms corresponding to the lifting joint are installed on the outer side of the sliding limiting mechanism, and the bottom of one side of the sliding limiting mechanism is fixedly connected with a sliding guide mechanism corresponding to the lifting joint. A mounting groove corresponding to the lifting jacking mechanism is formed in the center of the base. Through the sliding limiting mechanism, the lifting jacking mechanism, the fixed-point locking mechanism and the sliding guide mechanism which are simple in design, a standard knot can be quickly assembled and fixed at the bottom of a tower crane, operation is convenient, meanwhile, no large construction risk exists, and the device is worthy of vigorous popularization.

    本发明提供一种塔机升降装置,涉及工程机械技术领域。该种塔机升降装置,包括基座,所述基座的顶部固定连接有滑动限位机构,所述滑动限位机构的中心滑动连接有升降节,所述基座的中心设置有与升降节相对应的升降顶升机构,所述滑动限位机构的外侧安装有多个与升降节相对应的定点锁紧机构,所述滑动限位机构一侧的底部固定连接有与升降节相对应的滑动导向机构;所述基座的中心开设有与升降顶升机构相对应的安装槽。通过设计简单的滑动限位机构、升降顶升机构、定点锁紧机构以及滑动导向机构,可以在塔机的底部快速完成对标准节的组装固定,既方便操作,同时也没有较大的施工风险,值得大力推广。
