The invention belongs to the technical field of jacking mechanisms, and particularly relates to a jacking mechanism for a crane working platform. Through cooperation of the first rotating shaft, the second rotating shaft, the connecting rod, the two-way lead screw, the movable rod and the first hollow rod, the placing plate can be supported through a plurality of supporting points, so that the overall stability of the placing plate can be improved, the working safety of workers can be improved, and the requirements of users can be met. According to the device, through cooperation of a threaded rod, a driving bevel gear, a driven bevel gear and a fixing rod, the overall height of the protection net can be adjusted according to the requirements of a user, so that the protection range of the device can be expanded, the possibility that workers fall down accidentally is reduced, and then the practicability of the device can be improved.

    本发明属于顶升机构技术领域,尤其涉及一种吊车工作平台顶升机构。本发明通过第一转轴、第二转轴、连接杆、双向丝杆、活动杆和第一空心杆之间的配合,可以通过多个支撑点对放置板进行支撑,从而可以增加放置板的整体稳定性,进而可以提高工作人员的工作安全性,能够满足使用者的需求。本发明中,通过螺纹杆、主动锥齿轮、从动锥齿轮和固定杆之间的配合,可以根据使用者的需求来调节防护网的整体高度,从而可以扩大其防护范围,降低了工作人员意外坠落的可能性,进而可以提高该装置的实用性。
