The invention discloses a single-ship double-main-hook pile turning method for a large-diameter single pile, which adopts a main lifting hook and an auxiliary lifting hook, the two lifting hooks are respectively connected with a transition connecting mechanism through a first support beam lifting appliance and a second support beam lifting appliance, and a main lifting belt of the transition connecting mechanism is connected with two lifting lugs on the large-diameter single pile in a lifting manner; a tail slipping mechanism capable of being separated automatically is designed, the upper end of the tail slipping mechanism is connected to the main lifting hook, and a tail slipping clamp at the lower end of the tail slipping mechanism is connected to the bottom of the large-diameter single pile. In the process of lifting and overturning a large-diameter single pile, the pile overturning posture can be adjusted in real time by controlling the rising and falling amount of the main lifting hook and the auxiliary lifting hook, and the flexibility and maneuverability of pile overturning are improved. After the pile bottom falls to the seabed mud surface, the tail slipping clamp can be automatically separated from the pile bottom, the tail slipping steel wire rope can be separated from the main hook through lifting of the auxiliary hook, and recovery of the tail slipping clamp is completed; and finally, the double lifting hooks synchronously lift until the single pile is erected and pile turning is completed, and rapid and flexible lifting and turning of the large-diameter single pile are achieved.
本发明公开了一种单船双主钩大直径单桩翻桩方法,该方法采用了主吊钩和辅助吊钩两个吊钩,这两个吊钩分别通过第一支撑梁吊具、第二支撑梁吊具与过渡连接机构连接,过渡连接机构的主吊带再与大直径单桩上的两个吊耳吊接;并且设计了可自动脱离的溜尾机构,溜尾机构的上端连接在主吊钩上,溜尾机构下端的溜尾钳连接在大直径单桩桩底。在大直径单桩抬吊和翻桩的过程中,可通过控制主吊钩和辅助吊钩起落量来实时调整翻桩姿态,提高了翻桩的灵活机动性。待桩底落至海床泥面后,溜尾钳能够自动脱离桩底,通过副钩提升能够使溜尾钢丝绳脱离主钩,完成溜尾钳的回收;最后双吊钩同步提升,直至单桩竖立完成翻桩,实现了大直径单桩快速、灵活的抬吊翻身。
