The invention discloses a jacking supporting structure and a jacking device for a hydraulic cylinder of a coal mill. The bottom of the hydraulic cylinder is mounted on a hydraulic cylinder base through a knuckle bearing; the jacking support structure comprises at least two sets of support structures; each supporting structure comprises hoops arranged on different axial sections of the hydraulic cylinders in a sleeving mode, the hoops are connected with a plurality of telescopic rods extending in the radial directions of the different hydraulic cylinders, the extending ends of the telescopic rods are connected with bottom supports, and the bottom supports are horizontally arranged on hydraulic cylinder bases. And a hydraulic cylinder base mounted at the bottom of the hydraulic cylinder is connected with a bottom support horizontally arranged on the hydraulic cylinder base. By means of the jacking supporting structure, the hydraulic cylinder only with the lower end capable of being rotationally fixed can be effectively and vertically fixed and supported, the hydraulic cylinder can be conveniently disassembled and assembled, and the danger in the assembling process is greatly reduced.

    本发明公开了一种磨煤机液压缸的顶升支撑结构及顶升装置,液压缸底部经关节轴承安装于液压缸底座上;所述顶升支撑结构包括,至少两套支撑结构;各套支撑结构包括,套设于液压缸不同轴向截面的抱箍,抱箍连接有多个沿不同液压缸径向方位延伸的伸缩杆,各伸缩杆的延伸端与底撑相连,底撑水平设置于液压缸底座上。液压缸底部安装的液压缸底座上水平设置的底撑相连。通过上述顶升支撑结构,使得仅下端可旋转固定液压缸可以被有效进行垂直固定支撑,便于对液压缸进行拆卸安装操作,大大的降低了装配过程中的危险性。
