The invention belongs to the field of aviation equipment design, and particularly relates to an electric release device for an aviation cargo lifting belt. An existing releasing rope adopts a cutter to cut off the rope, gunpowder is filled in the cutter and detonates after being electrified, and the rope has strict requirements for storage, transportation and use. And the cutter cannot be reused. The device comprises a limiting block, a rope F, a rocker A and a crank C which are fixed on a machine body, the limiting block is provided with a lever E and a clamping groove, and a connecting rod B is arranged between the rod part of the rocker A and the movable end of the crank C; the movable end of the rope F is provided with a lantern ring; the crank C is controlled by a motor, one end of the lever E is supported or released through the rocker A, and the lantern ring is locked in the clamping groove or released from the clamping groove through the other end of the lever E. The lifting device has the advantages of being large in locking force, fast in unlocking, safe and reliable, the rope for fixing the lifting belt can be reused, and the automation degree is high.
本发明属于航空设备设计领域,具体涉及一种航空货物吊装带的电动释放装置。现有释放绳索采用切割器切断绳索,切割器内部装有火药,通电后引爆,其存储、运输、使用有严格要求;切割器不能重复利用。本发明包括固定在机体上的限位块、绳索F、摇杆A和曲柄C,其中在所述限位块上具有杠杆E和卡槽,在所述摇杆A的杆部与曲柄C的活动端之间具有连杆B;所述绳索F的活动端具有套环;所述曲柄C由电机控制,通过摇杆A对杠杆E的一端进行支撑或者释放,由杠杆E的另一端将套环锁定在卡槽中或者从卡槽中释放。省去了火工品的使用,具有锁紧力大、解锁快、安全可靠的优点,且固定吊装带的绳索可重复利用,自动化程度高。
