Special lifting appliance and lifting method for lifting cast-in-place pile ultra-long reinforcement cages
The invention discloses a special lifting appliance and lifting method for lifting cast-in-place pile ultra-long reinforcement cages. The special lifting appliance is provided with a carrying pole cross beam with a main lifting steel cable between the two ends, and a left lifting assembly and a right lifting assembly are symmetrically arranged at the two ends of the carrying pole cross beam. The appliance and method have the beneficial effects that through the lifting method, due to the fact that the tightness level and balance of a left double-lifting-point steel cable and a right double-lifting-point steel cable can be automatically adjusted when the reinforcement cages are lifted through a left fixed pulley and the right fixed pulley, the reinforcement cages can automatically adapt to the change of lifting angle in the air, and stable lifting is always kept; and the appliance and method can enable the ultra-long reinforcement cages to be directly lifted into pile holes through one-time welding forming, and have the characteristics that the labor and time are saved, lifting is safe, stable and reliable, the construction quality is guaranteed and the construction efficiency is improved.
本发明公开了一种吊装灌注桩超长钢筋笼的专用吊具及其吊装方法。该专用吊具设置了包括两端之间设有一条起吊主钢缆的扁担横梁，在所述扁担横梁的两端部设有相对称的左部吊装组件和右部吊装组件；本发明的有益效果是：其吊装方法中，由于左部定滑轮和右部定滑轮可使钢筋笼起吊时自动调整左部双吊点钢缆和右部双吊点钢缆的松紧程度和平衡，使钢筋笼在空中自动适应起吊角度的变化，始终保持平稳起吊。本发明能使超长钢筋笼一次焊接成型直接吊装进入桩孔，具有省工省时，起吊安全平稳可靠，保证施工质量，提高施工效率的特点。
