The invention discloses an anti-torsion lifting appliance for lifting a helicopter. The anti-torsion lifting appliance comprises an anti-torsion device, a triangular lifting frame, a square frame and an auxiliary lifting hook, the anti-torsion device comprises a circular lock disc and two connecting rod assemblies symmetrically and fixedly arranged above the circular lock disc, the top ends of connecting rods at the symmetrical positions in the two connecting rod assemblies are fixedly connected to form two hanging points, and the two connecting rod assemblies and the circular lock disc are fixedly hung on a web frame beam of the helicopter through the two hanging points. The circular lock disc is provided with at least one set of clamping grooves in the radial direction and used for clamping the triangular hanging bracket into one set of clamping grooves of the circular lock disc, so that the top end of the triangular hanging bracket is located between the two sets of connecting rod assemblies, the two bottom ends symmetrically arranged in the triangular hanging bracket are located below the circular lock disc, and the square frame is connected through the two bottom ends of the triangular hanging bracket. According to the technical scheme, the problems that due to the fact that an existing helicopter external hanging system can only conduct single-degree-of-freedom constraint, when goods are subjected to unbalanced force/torque, the goods are twisted with a sling as the axis, the posture of the goods cannot be controlled, and precise helicopter hoisting cannot be conducted are solved.

    本发明公开一种用于直升机吊装的防扭转吊具,包括:防扭转装置、三角吊架、方形架和辅助吊钩;防扭转装置包括:1个圆形锁盘,对称固定设置在圆形锁盘上方的2组连杆组件,2组连杆组件中对称位置的连杆顶端固定连接,形成2个吊挂点,用于通过2个吊挂点将2组连杆组件和圆形锁盘固定吊装在直升机的机腹框梁上;圆形锁盘沿径向设置有至少一组卡槽,用于将三角吊架卡合在圆形锁盘的其中一组卡槽内,使得三角吊架的顶端位于2组连杆组件之间,并使得三角吊架中对称设置的两个底端位于圆形锁盘的下方,且通过三角吊架的两个底端连接方形架。本发明提供的技术方案解决了现有的直升机外吊挂系统,由于只能进行单自由度约束,从而导致货物受到不平衡的力/力矩时,会以吊索为轴发生扭转,从而导致无法控制货物的姿态,且无法进行直升机精准吊装的问题。
