The invention discloses a lifting device for protecting the integrity of a precast pile body and a lifting method thereof.The lifting device comprises a column sleeve, sliding grooves are formed in the inner wall of the column sleeve, the multiple sliding grooves are formed in the circumferential direction of the column sleeve at intervals, and the lower ends of the sliding grooves penetrate through the lower end face of the column sleeve; the lower end of the retaining piece is installed in the sliding groove in a turnover mode, the column sleeve is provided with a hole channel communicated with the sliding groove, and the hole channel is aligned to the upper end; the anti-falling part is telescopically mounted in the through hole; the lifting hook comprises a supporting part, a bearing part and a cable connecting part, the bearing part is connected between the lower end of the supporting part and the lower end of the cable connecting part, a hook opening is formed between the upper end of the supporting part and the cable connecting part, the side wall of the column sleeve is arranged in the hook opening in a sliding mode, the bearing part is supported on the lower end face of the column sleeve, and the supporting part is arranged in the sliding groove in a sliding mode; the counter-force slope surface of the supporting part is supported on the lower end face of the retaining piece, and the cable connecting part is connected with a sling. The problem that the integrity of the pile body of the precast pile is easily affected due to the fact that no effective hoisting protection measure is provided for hoisting after the precast pile enters the field is solved.

    本发明公开了一种用于保护预制桩桩身完整性的起吊装置及其起吊方法,包括:柱套,柱套的内壁形成有滑槽,多个滑槽沿柱套的周向方向间隔设置,滑槽的下端贯穿柱套的下端面;止退件,止退件的下端可翻转地安装于滑槽中,柱套开设有连通于滑槽的孔道,孔道对准于上端;防脱件,可伸缩地安装于穿孔中;吊钩,包括支撑部、承托部和连索部,承托部连接于支撑部的下端和连索部的下端之间,支撑部的上端与连索部之间形成钩口,柱套的侧壁滑设于钩口中,承托部支撑于柱套的下端面,支撑部滑设于滑槽中,支撑部的反力坡面支撑于止退件的下端面,连索部连接有吊索。本发明解决了预制桩进场后的起吊没有有效的保吊措施,容易影响预制桩桩身的完整性的问题。
