The prefabricated pipe pile lifting device comprises a rigid sleeve, a first threaded ring, a screw rod, a second threaded ring, an upper supporting rod, a lower supporting rod, a supporting plate and a positioner. The rigid sleeve and the first threaded ring are arranged on the upper portion of the vertically-arranged screw in a sleeving mode, and the lower end of the rigid sleeve is fixedly connected with the upper end of the first threaded ring. The first threaded ring is in threaded connection with the screw rod; the second threaded ring is connected to the screw in a threaded mode and located below the first threaded ring, and the first threaded ring, the second threaded ring and the screw are opposite in thread turning direction. The upper end of the upper supporting rod is rotationally connected with the first threaded ring, the lower end of the lower supporting rod is rotationally connected with the second threaded ring, and the lower end of the upper supporting rod and the upper end of the lower supporting rod are rotationally connected with the supporting plate. And the positioner is fixed at the lower end of the screw rod. According to the hoisting device, the prefabricated pipe pile can be fixed more firmly and reliably, and deviation and dislocation can be reduced.

    本发明公开一种预制管桩起吊装置,包括:刚性套筒、第一螺纹环、螺杆、第二螺纹环、上支撑杆、下支撑杆、支撑板和定位器。所述刚性套筒和第一螺纹环均套在竖向设置的螺杆的上部,且所述刚性套筒的下端与第一螺纹环的上端固定连接。所述第一螺纹环与螺杆螺纹连接;所述第二螺纹环螺纹连接在螺杆上且位于所述第一螺纹环的下方,所述第一螺纹环、第二螺纹环与螺杆之间的螺纹旋向相反。所述上支撑杆的上端与第一螺纹环转动连接,所述下支撑杆的下端与第二螺纹环转动连接,且所述上支撑杆的下端、下支撑杆的上端均与所述支撑板转动连接;所述定位器固定在螺杆的下端。本发明的上述起吊装置不仅对预制管桩的固定更加牢固可靠,而且还能够减少偏差错位。
