The invention relates to the technical field of hydraulic lifting, and discloses a hydraulic lifting device which comprises a base frame, a hydraulic oil cylinder and a platform frame, first shear fork arms are arranged on the two sides of one end of the base frame, second shear fork arms are arranged on the two sides of one end of the platform frame, and a main shaft is fixed to the centers of the second shear fork arms; the first shear fork arms are rotationally connected with the two ends of the main shaft, a lower cross rod is arranged between the bottom ends of the second shear fork arms, and an upper cross rod is arranged between the upper half portions of the first shear fork arms. The problem that equipment and personnel are injured due to sudden descending of the platform frame is avoided, in addition, through jacking supporting of the supporting top plate, pressure maintaining does not need to be conducted on the hydraulic oil cylinder, the height of the hydraulic lifting device can be kept, and therefore the pressure maintaining time of the hydraulic oil cylinder is shortened, and the service life of the hydraulic oil cylinder is prolonged.
本发明涉及液压升降技术领域,公开了一种液压升降装置,包括:底座框架、液压油缸和平台框架,所述底座框架一端两侧设有第一剪叉臂,所述平台框架一端两侧设有第二剪叉臂,所述第二剪叉臂中央固定有主轴,所述第一剪叉臂与主轴两端转动连接,所述第二剪叉臂底端之间设有下横杆,所述第一剪叉臂上半部之间设有设有上横杆,本发明通过支撑顶板固定第一剪叉臂和第二剪叉臂之间的角度,避免出现平台框架突然下降造成设备和人员伤害的问题,此外通过支撑顶板的顶紧支撑,也能够无需对液压油缸进行保压,液压升降装置也能够保持高度,从而减少液压油缸的保压时间,延长液压油缸的寿命。
