The invention relates to hoisting equipment, in particular to a hoisting clamp for a prestressed concrete solid square pile. The hoisting clamp comprises a hoisting arm I, a hoisting arm II, a transversely arranged pull rod and two clamping plates, wherein the upper end of the hoisting arm I is hinged to the upper end of the hoisting arm II to form a herringbone shape, a positioning ring is weldedto the side surface of the hoisting arm II, a lug plate is welded to the left end of the pull rod to be connected with the hoisting arm I, the right end of the pull rod penetrates through the positioning ring to be in screwed connection with the hoisting arm II, hoisting rings for hoisting are arranged on the two sides of the hoisting arm I and the hoisting arm II correspondingly, and the two clamping plates are arranged at the lower ends of the hoisting arm I and the hoisting arm II correspondingly. According to the hoisting clamp, the hoisting tool has good universality, the square pile isclamped more safely and reliably in the hoisting process, local crushing of the concrete square pile is avoided, potential safety hazards are reduced, a hoisting posture of the square pile can be improved, the square pile can vertically fall into a pile foundation pit, and accurate hoisting falling points can be conveniently controlled.
本发明涉及吊装设备,具体涉及一种用于预应力混凝土实心方桩的吊装夹具,包括吊臂Ⅰ、吊臂Ⅱ、横向设置的拉杆和两个夹板,所述吊臂Ⅰ和吊臂Ⅱ上端铰接呈人字形,所述吊臂Ⅱ的侧面焊有定位环,所述拉杆的左端焊接耳板以连接吊臂Ⅰ、右端穿过定位环与吊臂Ⅱ螺接;所述吊臂Ⅰ和吊臂Ⅱ的两侧均设有起吊用的吊环;两个所述夹板分别设在吊臂Ⅰ和吊臂Ⅱ的下端。本发明的吊具有良好的通用性,吊装过程中对方桩的夹持更加安全可靠,不会对混凝土方桩造成的局部压溃,减少安全隐患;可以改善方桩的吊装姿态,方桩可以竖直落入桩基坑内,便于控制吊装准落入点。
