The invention relates to a cast-in-place pile body hoisting technology, in particular to a cast-in-place pile reinforcement cage hoisting device and a hoisting process for supporting an ultra-deep foundation pit. The actions that the movable plate gets close to the connecting plate and gets away from the connecting plate are completed by adopting power-on and power-off of the electromagnet, when the movable plate gets close to the connecting plate, the grabbing hook and the supporting claw move outwards under the action of the driving rod and the connecting rod, and the supporting claw swings outwards relative to the grabbing hook in the outward moving process and gets away from the connecting plate after moving to the outermost side. The multiple hoisting main body structures are arranged in the reinforcement cage in the length direction, the multiple hoisting main body structures are arranged in series, and it can be ensured that structural deformation does not occur in the posture adjusting process of the reinforcement cage; the auxiliary hoisting equipment can be automatically unhooked from a stirrup and a main reinforcement at the bottom end of the reinforcement cage through the gravity action of a lifting hook of the auxiliary hoisting equipment after the posture is adjusted.
本发明涉及灌注桩桩身吊装技术,具体为一种超深基坑支护用灌注桩钢筋笼吊装装置及吊装工艺。本发明通过采用电磁铁的通断电,完成活动板靠近连接板和远离连接板的动作,当靠近连接板时,经过驱动杆、连接杆作用将抓钩和托爪向外侧移动,托爪外移过程中会相对抓钩进行外摆,运动到最外侧后,完成与钢筋笼的主筋和箍筋的连接固定,通过在钢筋笼内部沿长度方向设置多个起吊主体结构,多个起吊主体结构串联布设,能够确保钢筋笼在姿态调整过程中不会出现结构变形,辅助吊装设备在姿态调整后通过自身吊钩的重力作用能够和钢筋笼底端的箍筋和主筋自动脱钩。
