The invention provides a counterweight ball special for helicopter sling method operation, which comprises a main hemisphere, a pressing plate and an auxiliary hemisphere, wherein the main hemisphereis provided with a first radial groove and a boss, one end of the boss is connected with the bottom surface of the main hemisphere, the first radial groove is arranged on the bottom surface along thediameter direction of the main hemisphere, and the first radial groove penetrates through the boss and is communicated with the outer side of the other end of the boss; the pressing plate is of an annular structure, the pressing plate is detachably connected with the bottom surface of the main hemisphere, the sling can be pressed in the first radial groove through the end surface of one side of the pressing plate, and the boss can penetrate through the middle annulus of the pressing plate and is arranged on the other side of the pressing plate; and the auxiliary hemisphere is provided with a groove matched and inserted with the boss, and the auxiliary hemisphere is connected with the end surface of the other side of the pressing plate. The counterweight ball special for helicopter sling method operationhas the beneficial effects that the sphereis adopted as a counterweight device for the sling method operation, the streamline is good, the wind resistance coefficient is low, the sphereis of an electrodeless structure and cannot deflect obviously towards a certain direction in use, and the purpose of improving the safety of the sling method operation of the helicopter can be achieved.

    本发明提供了一种直升机吊索法作业专用配重球,包括:主半球,设置有第一径向槽和凸台,凸台的一端与主半球的底面连接,第一径向槽沿主半球的直径方向设置在底面上,且第一径向槽贯穿凸台并与凸台的另一端外侧连通;压板,呈圆环状结构,压板与主半球的底面能拆卸地连接,压板的一侧端面能够将吊索压紧于第一径向槽中,凸台能够穿过压板的中部环空并置于压板的另一侧;副半球,设置有与凸台配合插接的凹槽,副半球与压板的另一侧端面连接。本发明的有益效果是,采用球体作为吊索法作业的配重装置,流线型好,风阻系数低,且球体为无极结构,不会在使用中向某一方向有明显的偏转,能够达到提高直升机吊索法作业安全性的目的。
