The invention belongs to the technique of weight deduction of aircraft structure tests, and particularly relates to a following weight-deducting pulley block system for aircraft structure tests. The following weight-deducting pulley block system provided by the invention is good in structural stability, and can greatly improve the weight deducting precision of the aircraft structure tests. The pulley block system comprises adjustable connectors, a lever, fixed pulleys, a movable pulley, a steel cable and the like, wherein the fixed pulleys comprise a double pulley and a single pulley which are respectively arranged at two ends of the lever; one end of the steel cable is connected with a counterbalancing weight, and the other end of the steel cable goes around the single pulley, the double pulley and the movable pulley sequentially, and then, are fixed on the fixed point of the double pulley; a test piece which needs weight deduction is connected to a position under the movable pulley; the adjustable connectors are connected to the two ends of the lever and fixed at suspension points. The pulley block system is stable in tests, and effectively solves the problem of structural weight deduction in large-deformation tests; the pulley block system can regulate the load proportion of deducted weight to the counterbalancing weight in a steel cable winding manner; the pulley block system is flexible and convenient to mount, and is good in universality and practicability.
