The invention provides the welding-free hoisting fixture capable of avoiding groove damage. The fixture comprises a main hoisting set and an auxiliary hoisting set, the main hoisting set is mainly composed of a main hook and a steel wire rope which are matched with a main upper elevator and a main lower elevator which are arranged in a mirror image mode, and the auxiliary hoisting set is mainly composed of an auxiliary hook and a steel wire rope which are matched with an auxiliary upper elevator and an auxiliary lower elevator. Wherein the main upper lift sub, the main lower lift sub, the auxiliary upper lift sub and the auxiliary lower lift sub are all of L-shaped groove structures, macromolecule gaskets are detachably arranged in grooves of the L-shaped groove structures, through cooperative operation of the main lifting set and the auxiliary lifting set, lifting and overturning of the workpieces of the annular main body structure are completed, and the technical problem of lossless lifting of the workpieces of the annular cylinder structure is solved. According to the welding-free hoisting fixture, due to the arrangement of the main hoisting group and the auxiliary hoisting group, tedious treatment operation before and after welding caused by welding of a lifting lug is avoided, meanwhile, damage to a workpiece caused by repeated welding and polishing is also avoided, the hoisting safety and reliability are guaranteed, and the welding-free hoisting fixture is suitable for avoiding groove damage.

    本发明提供了一种避免坡口损伤的免焊接吊装卡具。该卡具通过主吊装组和副吊装组,其中主吊装组主要由主钩与钢丝绳配合两个镜像设置的主上吊卡和主下吊卡组成,副吊装组主要由副钩与钢丝绳配合副上吊卡和副下吊卡组成,其中主上吊卡、主下吊卡、副上吊卡和副下吊卡均为L型槽结构,其槽内可拆卸的设有高分子垫片,通过主吊装组和副吊装组的协同作业,完成圆环型主体结构工件吊装和翻转,解决圆环型柱体结构工件的无损吊装的技术问题。由于本发明通过主副吊装组的设置,避免因焊接吊耳带来焊前、焊后的繁琐处理作业,同时也避免因反复焊装打磨对工件造成的损害,保证吊装安全性和可靠性,适宜作为避免坡口损伤的免焊接吊装卡具应用。
