The invention discloses a hoisting device for a crane and a hoisting method of the hoisting device, and relates to the technical field of crane hoisting accessories. The multiple clamping units are arranged in the profiling inner supporting units, simulation profiling can be conducted according to the shape of the inner wall of the cylinder sleeve before hoisting, and therefore the outer wall shapes of the multiple profiling inner supporting units can be matched with the shape of the inner wall of the cylinder sleeve, and when the profiling inner supporting units make contact with the inner wall of the cylinder sleeve, the clamping units can clamp the inner wall of the cylinder sleeve. The clamping units in multiple positions can abut against the inner wall of the cylinder sleeve, the multi-point expanding and clamping effect is achieved, accordingly, the friction force between the profiling inner supporting units and the inner wall of the cylinder sleeve can be increased, it is guaranteed that the hoisting mechanism can be stably connected with the cylinder sleeve, the situation that the cylinder sleeve and the hoisting mechanism are accidentally separated in the hoisting process is avoided, and the hoisting efficiency is improved. And meanwhile, acting force generated in the hoisting process is evenly dispersed to the multiple clamping point positions, and the situation that the inner wall of the cylinder sleeve is damaged due to the fact that the clamping force is excessively concentrated is avoided.

    本发明公开了一种起重机用的吊装装置及其吊装方法,本发明涉及起重机吊装配件技术领域。通过在仿形内撑单元中设置多个夹持单元,能够在吊装前根据缸套内壁的形状进行模拟仿形,从而使得多个仿形内撑单元的外壁形状能够和缸套内壁形状相契合,在仿形内撑单元和缸套内壁相接触时,使得多个位置上的夹持单元均能够和缸套内壁相抵,实现多点撑胀夹持的效果,从而能够增大仿形内撑单元和缸套内壁之间的摩擦力,保证吊装机构能够和缸套之间形成稳固的连接,避免吊装过程中缸套和吊装机构意外分离的情况,从而提高吊装过程的安全性,同时使得吊装时产生的作用力均匀分散至多个夹持点位上,避免缸套内壁因夹持力过于集中而损伤的情况。
