The invention discloses a penetrating type lifting appliance and a lifting method for a heavy prefabricated concrete stand column. The lifting appliance comprises a steel sleeve which is pre-buried and transversely penetrates through the concrete stand column, and the steel sleeve is sleeved with a steel lifting shaft; a rope sleeve of the traction rope sleeves the part, extending out of the opening of the steel sleeve, of the expanded head of the steel hanger shaft; each expanded head is sleeved with an annular steel baffle, and the outer surface of each annular steel baffle is connected with a steel end plate through a plurality of connecting rods; the steel end plate is connected with the outer end face of the expanded head on the same side through a fastening bolt; the method is characterized in that a fastening bolt, an integral check block, a steel casing and a steel base plate at the left end of a steel hanger shaft are sequentially disassembled; then the outer hanging ring at the right end of the steel hanging shaft is tied and pulled through a first hanging belt, so that the steel hanging shaft transversely moves rightwards by a certain distance to expose the inner hanging ring of the arc-shaped plate, and a second hanging belt is tied; and the steel lifting shaft is transversely lifted to the ground in the form of a left lifting point and a right lifting point. According to the lifting appliance and the lifting method, the lifting process is firm, safe and stable.

    本发明公开一种重型预制混凝土立柱的贯穿型吊具和吊装方法,该吊具包括预埋并横向贯穿混凝土立柱的钢套管,钢套管套合有一根钢吊轴;牵引绳的绳套套在钢吊轴扩大头伸出钢套管开口的部分;每个扩大头套有一块环形钢挡板,每块环形钢挡板外表面经多根连杆与一块钢端板连接;该钢端板和同侧的扩大头外端面经一个紧固螺栓连接;该方法的关键在于:依次拆卸钢吊轴左端的紧固螺栓、整体式挡块、钢护筒和钢垫板;然后用第一吊带系住并拉拽钢吊轴右端的外吊环,使钢吊轴向右横移一段距离以露出弧形板内吊环并系上第二吊带;以左右两个吊点的形式将钢吊轴呈横向吊运至地面。该吊具和吊装方法使吊装过程牢固、安全、稳定。
