(3) summary of the invention
The deficiency of, poor reliability not high, the utility model for the close/open machine complex structure that overcomes existing automatic transfer switching electric appliance, commutation accuracy provide a kind of simple in structure, the rotating shaft reversing arrangement of automatic transfer switching electric appliance accurately and reliably commutates.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of rotating shaft reversing arrangement of automatic transfer switching electric appliance, the output of this rotating shaft reversing arrangement connects the moving contact system, described rotating shaft reversing arrangement comprises mounting panel, be arranged on rotating main shaft on the mounting panel, be rigidly connected adjusting cantilever, location cantilever, cam with main shaft, described adjusting cantilever and moving contact system are hinged, described location cantilever and resetting device are hinged, and resetting device is installed on the mounting panel; Described cam is provided with chute, chute comprises last arc chute, the arc lower chute that is interconnected, the side of cam is provided with solenoid actuated mechanism, described solenoid actuated mechanism comprises reducible electromagnetic actuation device, push rod and push rod, the output of described electromagnetic actuation device is fixedlyed connected with push rod, one end of described push rod and push rod is hinged, and the other end of described push rod is connected with described chute slidably by pin.
Further, described resetting device comprises gag lever post, is socketed in the back-moving spring on the gag lever post, and an end of described gag lever post is hinged with the location cantilever, and the other end of described gag lever post is fixedlyed connected with mounting panel.
Further again, described electromagnetic actuation device comprises housing, is installed in electromagnet mechanism, back-moving spring in the housing, and the output of described electromagnet mechanism connects described push rod, and described back-moving spring is socketed on the push rod.
Operation principle of the present utility model is: its push rod promotes push rod when electromagnetic actuation, push rod promotes to be rigidly connected rotating shaft with cam along the cam chute and rotates, rotating shaft drives and is rigidly connected adjusting cantilever rotation with it, regulate cantilever and drive the combined floodgate (or separating brake) that contact system is realized switch, location cantilever one end is fixedlyed connected with mounting panel, and the other end keeps the state of combined floodgate (or separating brake) by spring; Electromagnet outage after the action of close a floodgate (or separating brake) is finished makes push rod drive push rod within it and resets under the counter-force effect of portion's spring, prepare for separating brake (or combined floodgate) next time, realizes the purpose of commutation.This device has taken into full account the suction size cases of electromagnet each trip segment in attracting process, but simple in structure, and commutation is a kind of desirable reversing arrangement accurately and reliably.
The beneficial effects of the utility model mainly show: simple in structure, the commutation accurately and reliably.
