Compared with a multi-point fixing sling, the lifting sling is simpler, the supporting columns are inserted into the cylinder barrel, the cylinder body is prevented from rotating around the supporting columns, and the stability of the lifting process is improved under the condition that the lifting steps are not increased. And the cylinder body can be conveniently hoisted in a state that the cylinder barrel lies flat.

    本发明涉及一种用于发动机缸体的专用吊具及起吊方法,专用吊具包括:主体;吊臂,所述吊臂设于所述主体,所述吊臂远离所述主体的一端设有吊钩;若干水平延伸的支撑柱,所述支撑柱间隔的设置于所述主体上,所述支撑柱位于所述吊臂的下方,且所述支撑柱与所述吊臂位于所述主体的同一侧,所述支撑柱用于水平的插入缸体的缸筒中起吊缸体。相比多点固定吊索更简单,其通过多个支撑柱插入缸筒中,避免了缸体绕支撑柱的旋转,在不增加吊装步骤的情况下提高了吊装过程的稳定性。可方便的以缸筒平躺的姿态吊装缸体。
