The invention discloses an electrical safety working platform with a stable mechanical structure. The electrical safety working platform sequentially comprises a bottom plate, a supporting platform, alifting mechanism, an operating platform and a horizontal moving mechanism from bottom to top, wherein the lifting mechanism comprises a two-way lead screw, and a plurality of groups of telescopic supporting rods which are arranged in an X-shaped crossed mode, the two ends of the two-way lead screw are rotatably arranged on the supporting platform, one end of the two-way lead screw is provided with the supporting platform which is connected to a rotary disc; the two ends of the two-way lead screw are provided with lower slide blocks in a sleeving mode; the two lower ends of the telescopic supporting rods which are arranged in the X-shaped crossed mode are hinged with the lower slide blocks separately; the two ends of the telescopic supporting rod which is arranged in the X-shaped crossedmode at the uppermost end are separately hinged with upper slide blocks; and the upper slide blocks are slidably arranged in slide slots in the lower surface of the operating platform. Through liftingof a two-way four-rod drive lifting mechanism, a self-locking function is achieved between the two-way lead screw and the lower slide blocks which are in threaded connection, so that safety is higher, and stability is stronger.
本发明公开了一种机械结构稳定的电力安全工作平台,从下到上依次包括底板、支撑平台、升降机构、操作平台、水平移动机构,升降机构包括双向丝杆、多组X型交叉设置的伸缩支撑杆,双向丝杆的两端转动设置在支撑平台上,且双向丝杆的一端设置有支撑平台与转盘连接,双向丝杆的两端套接设置有下滑块,X型交叉设置的伸缩支撑杆的两下端分别与下滑块铰接设置,位于最上端的X型交叉设置的伸缩支撑杆的两端分别铰接有上滑块,上滑块滑动设置在位于操作平台下表面的滑槽内。本发明结构通过设置的双向四杆驱动升降机构的升降,螺纹连接的双向丝杆和下滑块之间具有自锁功能,安全性更高,稳固性更强。
