The invention discloses a shear arm type quick throwing method, which applies a lever principle, takes a high-strength bearing shaft as a fulcrum, and acts the gravity of an object on the end point of a shear arm, a force loading device only needs to apply a half of total locking force, a shear arm device reaches a stress balance state, and a lock hook locks the object, so that the object can be thrown quickly. The force arm of the gravity of the object is far smaller than the force arms of the locking forces at the two ends of the shear arm device, so that the locking force applied by the force loading device is far smaller than the gravity of the object, and the purpose of driving large force with small force is achieved; by controlling the trigger force loading device to lose force, the lock hook has no locking force under the action of the gravity of an object, meanwhile, the gravity of the shear arm acts on the lock hook according to the lever principle, opening of the lock hook is accelerated, and the purpose that the lock hook rapidly throws the object is achieved. The problem of the locking force requirement of the lock hook and the problem of time needed for object throwing are comprehensively solved, the requirement for the locking force can be reduced in a multiplied mode, meanwhile, the time needed for throwing can be saved, and the lock hook has the advantages of being large in force with small force, short in throwing time, safe, reliable and the like.
本发明公开一种剪臂式快速投放方法,其运用杠杆原理,以高强度承力轴为支点,将物体重力作用于剪臂端点处,力加载装置只需施加二分之一的总锁紧力,剪臂装置便达到受力平衡状态,锁钩紧锁物体,由于物体重力的力臂远小于剪臂装置两端锁紧力的力臂,故力加载装置施加的锁紧力远小于物体重力,实现了“以小力博大力”的目的;通过控制触发力加载装置失力,锁钩无锁紧力受物体重力的作用,同时根据杠杆原理剪臂重力作用于锁钩,加速锁钩打开,实现了锁钩快速投放物体的目的。本发明全面解决了锁钩锁紧力需求的问题和投放物体所需时间的问题,能够成倍的降低锁紧力的需求同时又能节省投放所需时间,具有以小力博大力、投放时间短、安全可靠等特点。
