The invention discloses a helicopter hanging and putting device and method, belongs to the field of helicopter hanging and putting transportation, and effectively reduces the driving torque during cargo putting and reduces the size and weight of a cargo hook under the condition of ensuring reliable cargo putting through mutual cooperation of a lock catch, a cam, a hook and a limiting block. In the locking state, the reset spring enables the cam to have the trend of anticlockwise rotating around the cam shaft, and movement of the cam is limited through the limiting block. The gravity of goods enables the hook to push the large roller to drive the lock catch to have an anticlockwise rotation trend, and the lock catch is supported at the top end of the cam; when goods are thrown, the cam rotates clockwise, the gravity of the goods drives the hook to rotate clockwise, the lock catch rotates reversely, the hook is separated from the large roller, the goods slide down from the hook, at the moment, the distance between the hanging point of the goods and the rotating center of the hook is gradually increased, the torque is increased, and it is guaranteed that the goods can be thrown smoothly. And the purposes of small size and light weight of the device under the condition of the same maximum hanging load are achieved.

    本发明公开了一种直升机吊挂投放装置及方法,属于直升机吊挂投放运输领域,通过锁扣、凸轮、挂钩和限位块相互配合确保货物可靠投放的条件下,有效降低了投放货物时的驱动力矩,降低了货物挂钩的尺寸和重量。在锁闭状态,复位弹簧使凸轮具有绕凸轮轴逆时针旋转的趋势,通过限位块限制凸轮运动;货物的重力使挂钩推动大滚轮带动锁扣具有逆时针旋转的趋势,锁扣支撑在凸轮的顶端;投放货物时,凸轮顺时针旋转,货物重力带动挂钩顺时针旋转,锁扣逆时方向针旋转,挂钩从大滚轮中脱出,货物从挂钩上滑落,此时货物的吊挂点与挂钩旋转中心的距离逐步变长,力矩变大,确保货物能够顺利投放掉,实现在最大吊挂载荷相同情况下,装置体积小、重量轻的目的。
