The invention provides a self-control type lifting limiting device for installation of electrical automation equipment. The device comprises a box body, a top plate and a rotating shaft; two sets of lifting devices are arranged on the surface of a bottom plate in an aligned mode, and the lifting devices and a power device are in transmission through turbines and worms; a hexagonal block is arranged at one end of the rotating shaft, and the other end of the rotating shaft is fixedly connected with the auxiliary bevel gear; and the auxiliary bevel gear is meshed with a bevel gear set, and the auxiliary bevel gear is rotationally connected with the box body through a bearing. According to the device, a bidirectional lead screw penetrates through two sets of lower sliding blocks and is rotationally connected with a base, so that a scissor fork rod can be always located in the middle position below the top plate in the telescopic process, and the stability of the top plate in the lifting process is guaranteed; and through the arrangement of the hexagonal block, when a motor breaks down, a specific crank is inserted or a wrench is used for rotating the hexagonal block to replace a driving device to provide power for the lifting device, so that ascending or descending of the top plate is achieved.

    本发明提供一种电气自动化设备安装用自控式提升限位装置,包括箱体,顶板和转轴;所述底板表面对位设有两组升降装置,且升降装置与动力装置通过涡轮蜗杆传动;所述转轴一端设有六角块,且转轴另外一端与辅助锥齿轮固定连接;所述辅助锥齿轮与锥齿轮组相啮合,且辅助锥齿轮通过轴承与箱体转动连接。本发明中,通过双向丝杠贯穿两组下滑块并与底座转动连接的设置,使得剪叉杆在伸缩的过程中能够始终处于顶板下方的中间位置,保证了顶板在抬升过程中的稳定性,还通过六角块的设置,使得在电机发生故障装置时,通过插入特定的摇把或者利用扳手转动六角块,替代驱动装置给升降装置提供动力,从而实现顶板的上升或者下降。
