Fig. 2 is the front view two of the utility model to the state that hoists during product test
Fig. 3 is that the utility model is to the side view falling state during product test
The concrete meaning of number in the figure is: 1 is framework, and 2 is elevating mechanism, and 2-1 is that loop chain hangs, 2-2 is electromagnet, and 2-3 is armature suspension ring, and 2-4 is the first rope tool, 2-5 is the second rope tool, 2-6 is bolt, and 3 is product protective housing, and 4 is buffering effect test system, 5 is controller, 5-1 is master control cabinet, and 5-2 is display screen, and 6 is scale.
Embodiment
Embodiment one, see Fig. 1, Fig. 3, the utility model electromagnetism dipping sonobuoy type falling test stand, comprise elevating mechanism 2, framework 1, product protective housing 3, buffering effect test system 4, controller 5, described elevating mechanism 2 one end is fixedly connected with framework 1, the other end is flexibly connected with product protective housing 3, product protective housing 3 is electrically connected with the input end of buffering effect test system 4, the input end of buffering effect test system 4 signal output part connection control device 5, described controller 5 comprises master control cabinet 5-1 and display screen 5-2, described elevating mechanism 3 comprises loop chain and hangs 2-1, electromagnet 2-2, armature suspension ring 2-3, first rope tool 2-4, second rope tool 2-5, the bolt 2-6 of adjustment second rope tool 2-5 elasticated, described loop chain hangs 2-1 and is flexibly connected with electromagnet 2-2, electromagnet 2-2 is flexibly connected with armature suspension ring 2-3 by the first rope tool 2-4, armature suspension ring 2-3 is fixedly connected with one end of bolt 2-6 by the second rope tool 2-5, the other end of bolt 2-6 is flexibly connected with product protective housing 3.First rope tool 2-4 is safety rope, second rope tool 2-5 is wire rope, bolt 2-6 is flower basket bolt, safety rope and wire rope are 2, electromagnet 2-2 is coupled together by the two ends of 2 safety ropes and armature suspension ring 2-3, the two ends of armature suspension ring 2-3 are coupled together by 2 wire rope and 2 flower basket bolts again, and the other end of these 2 flower basket bolts is hooked on the suspension hook at two ends, product protective housing 3 top respectively.
