The invention discloses a speed-different type safety catcher self-locking reliability performance test machine which comprises a framework, a base plate 2 and an air pump. The framework is provided with two fixed plates, releasing mechanisms, one or two upper stop blocks, an impact pedestal, a control cabinet, a suspension ring, a weight block set, cylinders, movable plates, a sensor, movable plate gag lever posts, and a weight block gag lever post. Each releasing mechanism 5 comprises an electromagnet, a releasing pawl and a lever mechanism. The releasing pawl extends horizontally and inwardly to form a mobile platform capable of supporting the weight block set. The electromagnet and one end of the lever mechanism form a machinery linkage capable of tripping. The impact pedestal is arranged at a central position of the base plate. Center lines of the impact pedestal, the weight block set and the speed-different type safety catcher are superposed. The impact pedestal is provided witha counting sensor. The speed-different type safety catcher self-locking reliability performance test machine has the advantages of simple structure, low manufacture cost, good processing consistency,suitability of mass production and the like.
