The mode of operation of described switching cabinet spring operating mechanism describes by three working process:
Energy storage and making process: turned clockwise by actuator drives input cam by manpower or motor, input cam drives two rotating-table apparatus to turn clockwise, two rotating-table apparatus promotes two push plate device to move forward, meanwhile, switching-in spring, be stretched forward the while of tripping spring energy storage, lock plate also moves up simultaneously, at the end of energy storage, combined floodgate limit cam is drawn close to lock plate under button spring effect and is coordinated locking lock plate with the breach on lock plate, combined floodgate locking cam rotates at the first spring clockwise under influence, hold out against combined floodgate limit cam and combined floodgate limit cam is locked, lock plate just cannot move forward, so that switching-in spring, tripping spring remains on energy storage position, now, input cam continues to turn clockwise, then stir transmission arm by its first pusher dog to move to oblique rear, drive connecting lever counterclockwise motion, connecting lever drive cam shaft is rotated counterclockwise and promotes brake-dividing locking cam to rotate by camshaft, so that brake-dividing locking cam releases the spacing state of point lock limit cam, and then release spacing to output cam, owing to output cam and limit convex wheel plate are fixed together, switching-in spring release energy, thus drive position-arresting disk, output cam to turn clockwise fast, finally realize switch rapid closing.
Divide lock working process: be rotated counterclockwise by actuator drives input cam by manpower or motor, input cam is stirred dropout transmission arm by its 2nd pusher dog and is moved backward, thus drive combined floodgate locking cam to be rotated counterclockwise, realize the locking states thereof to combined floodgate limit cam, lock the spacing of plate is released, owing to tripping spring is still in energy storage state, tripping spring release energy, two push plate device is driven to move forward, simultaneously two rotating-table apparatus is rotated counterclockwise and driver output cam is rotated counterclockwise fast, thus realizes switch quick acting switching-off. Input cam is dividing in lock process counterclockwise, spacing due to what relieve transmission arm, transmission arm is under the effect of transmission arm reset spring, drive connecting lever clockwise motion, thus drive cam shaft turns clockwise, and then release spacing to brake-dividing locking cam, if now output cam has entered gate-dividing state, the dead bolt of lock limit convex is then divided to stretch out and enter the breach of output cam, simultaneously a point lock limit cam is locked by brake-dividing locking cam return, it is achieved spacing to mechanism's gate-dividing state.
Thread off and divide a lock working process: triggering by electrical apparatus release or other parts threads off drives arm or directly triggers dropout transmission arm, thread off and drive arm to promote dropout transmission arm to move backward, thus drive combined floodgate locking cam to be rotated counterclockwise, realize the locking states thereof of combined floodgate limit cam, lock the spacing of plate is released, owing to tripping spring is still in energy storage state, tripping spring release energy, two push plate device is driven to move down, two rotating-table apparatus is rotated counterclockwise simultaneously, two rotating-table apparatus driver output cam is rotated counterclockwise fast, thus realizes switch quick acting switching-off.Input cam is dividing in lock process counterclockwise, spacing due to what relieve transmission arm, transmission arm is under the effect of transmission arm reset spring, drive connecting lever clockwise motion, thus drive cam shaft turns clockwise, thus relieve brake-dividing locking cam spacing, if now output cam has entered gate-dividing state, the dead bolt of lock limit cam is then divided to stretch out and enter the breach of output cam, simultaneously a point lock limit cam is locked by brake-dividing locking cam return, it is achieved spacing to mechanism's gate-dividing state; This operating process can input cam stir dropout transmission arm lost efficacy or the emergency state under operation, thus ensure mechanism with time-division lock, avoid the unnecessary loss because mechanism cannot divide lock and cause.
