The invention provides a supporting and lifting type edge fixing safety lifting platform, and belongs to the technical field of lifting equipment. The supporting and lifting type edge fixing safety lifting platform comprises a base, a bearing platform, fork-shaped frame sets and a lifting device; the number of the fork-shaped frame sets is four, the four corners of the base and the four corners of the bearing platform are each provided with a fixed short shaft base, and the outer supporting arms of the four fork-shaped frame sets are all installed on the short shaft bases in a fixed rotating manner; the lifting device comprises a hydraulic pump station, hydraulic oil cylinders and a driving shaft rod; and the driving shaft rod is arranged in a bearing on an inner supporting arm at the joint between a bottom fork-shaped frame and an adjacent fork-shaped frame, the hydraulic oil cylinders are vertically installed between the base and the driving shaft rod, and long-strip-shaped tables are further arranged at the two sides of the base. The supporting and lifting type edge fixing safety lifting platform has the beneficial effects that the extension and contraction of the four fork-shaped frame sets are fixedly kept at the edge positions, and the force of the hydraulic oil cylinders acting on the driving shaft rod and the fork-shaped frame sets is vertical, so that the stability of the lifting platform can be greatly improved, the supporting force required by lifting is greatly reduced, the safety coefficient is improved, and the service life is prolonged.

    一种撑举式边缘固定安全升降平台,属于升降设备技术领域,包括底座、承载平台、叉形架组和升降装置;叉形架组设有四个,所述底座和承载平台的四个角部各安装有固定的短轴座,四个叉形架组的外支撑臂均呈固定旋转式安装在短轴座上;升降装置包括液压泵站、液压油缸和驱动轴杆;驱动轴杆设在底部叉形架与相邻叉形架之间交接位置的内支撑臂上的轴承内,液压油缸垂直安装在底座和驱动轴杆之间,底座两侧还设置了长条台;其有益效果是四个叉形架组的伸长和收缩均固定保持在边缘位置,液压油缸作用在驱动轴杆和叉形架组上的力是垂直的,可大大提高升降平台的稳定性,大大减少升降所需要的支撑力,提高了安全系数,延长了使用寿命。
