Described switch cubicle can be described by three courses of work with the working method of spring operating mechanism:
Energy storage and making process: turned clockwise by the actuator drives input cam by manpower or motor, input cam drives two rotating-table apparatus and turns clockwise, two rotating-table apparatus promote two push plate device and move forward, meanwhile, switching-in spring, the tripping spring energy storage that is stretched forward simultaneously, jam plate also moves up simultaneously, when energy storage finishes, the combined floodgate limit cam is drawn close to jam plate under the effect of button spring and is cooperated with breach on the jam plate and locks jam plate, the combined floodgate locking cam turns clockwise under the first spring action, hold out against to the combined floodgate limit cam and to the combined floodgate limit cam and lock, jam plate just can't move forward, thereby so that switching-in spring, tripping spring remains on the energy storage position; At this moment, input cam continues to turn clockwise, then stirring transmission arm by its first pusher dog moves to oblique rear, driving connecting lever moves counterclockwise, the connecting lever drive cam shaft is rotated counterclockwise and promotes the rotation of brake-dividing locking cam by camshaft, thereby so that the brake-dividing locking cam is removed the spacing state of separating brake limit cam, and then remove spacing to output cam, because output cam and limit convex wheel plate are fixed together, switching-in spring releases energy, thereby driving position-arresting disk, output cam turn clockwise fast, finally realize the switch rapid closing.
The separating brake course of work: be rotated counterclockwise by the actuator drives input cam by manpower or motor, it is mobile backward that input cam is stirred the dropout transmission arm by its second pusher dog, thereby driving the combined floodgate locking cam is rotated counterclockwise, realization is to the lock-out state release of combined floodgate limit cam, the spacing of jam plate is disengaged, because tripping spring still is in energy storage state, tripping spring releases energy, driving two push plate device moves forward, simultaneously two rotating-table apparatus are rotated counterclockwise and the driver output cam is rotated counterclockwise fast, thereby realize the switch quick acting switching-off.Input cam is in carrying out counterclockwise separating brake process, owing to removed spacing to transmission arm, transmission arm is under the effect of transmission arm return spring, driving connecting lever moves clockwise, thereby drive cam shaft turns clockwise, and then remove spacing to the brake-dividing locking cam, if this moment, output cam entered gate-dividing state, then the dead bolt of separating brake limit convex stretches out and enters the breach of output cam, the brake-dividing locking cam resets the separating brake limit cam is locked simultaneously, and realization is spacing to mechanism's gate-dividing state.
The dropout separating brake course of work: trigger the dropout actuating arm or directly trigger the dropout transmission arm by release or other parts, it is mobile backward that the dropout actuating arm promotes the dropout transmission arm, thereby driving the combined floodgate locking cam is rotated counterclockwise, realize the lock-out state release of combined floodgate limit cam, the spacing of jam plate is disengaged, because tripping spring still is in energy storage state, tripping spring releases energy, driving two push plate device moves down, simultaneously two rotating-table apparatus are rotated counterclockwise, two rotating-table apparatus driver output cams are rotated counterclockwise fast, thereby realize the switch quick acting switching-off.Input cam is in carrying out counterclockwise separating brake process, owing to removed spacing to transmission arm, transmission arm is under the effect of transmission arm return spring, driving connecting lever moves clockwise, thereby drive cam shaft turns clockwise, thereby removed spacing to the brake-dividing locking cam, if this moment, output cam entered gate-dividing state, then the dead bolt of separating brake limit cam stretches out and enters the breach of output cam, the brake-dividing locking cam resets the separating brake limit cam is locked simultaneously, and realization is spacing to mechanism's gate-dividing state; This operating process can input cam stir that the dropout transmission arm lost efficacy or the state of emergency under operate, thereby guarantee the at any time separating brake of mechanism, avoid the unnecessary loss that can't separating brake causes because of mechanism.
