The mechanical oscillation that rigid limit produces during for fear of separating brake, described main shaft the place ahead is provided with separating brake flexible limit device (30).
The working method of breaker operating mechanism of the present invention is as follows:
1) thermal energy storage process:
With reference to figure 2 and Fig. 3, energy storage motor gets electric rotation, and by chain pulling sprocket rotation, sprocket wheel drives coaxial mounted energy-storage crank arm and rotates, and the other end of energy-storage crank arm is by the bottom of chain pulling energy-stored spring, and energy-stored spring compresses; After energy-storage crank arm rotated through the dead point, under the pulling function of energy-stored spring, energy-storage crank arm was to side deflection certain angle, and under the effect of spring restoring force, cam is rotated counterclockwise simultaneously, and the projection on the cam withstands energy storage and keeps connecting lever, and cam can't continue rotation; This moment is drop-down by the connecting rod of combined floodgate cam control, stirs the clutch connecting lever and rotates, and clutch connecting lever band dynamic clutch makes motor output shaft separate with energy-storage system; Motor power is cut off in the action of energy storage auxiliary switch, and the energy storage indication forwards " energy storage " position to; Thermal energy storage process finishes.
2) making process:
With reference to figure 4, Fig. 5, Fig. 6 and Fig. 7, after energy storage finishes, depress switch knob or the making electromagnet pulse got electric, closing pawl is pushed, the upper end of closing pawl breaks away from energy storage and keeps connecting lever, energy storage keeps connecting lever to rotate under the twisting resistance effect of energy storage maintenance connecting lever self torsion spring, and combined floodgate cam driven combined floodgate connecting lever rotates under the effect of energy-stored spring, rotates thereby drive main shaft; The combined floodgate connecting lever separated with the resilience of combined floodgate flexible limit Contact when main shaft turned over maximum angle, and the combined floodgate retainer is blocked by the movable end of separating brake connecting lever, kept "on" position, simultaneously, closed a minute indication and forwarded the combined floodgate indicating positions to; Drive clutch connecting lever connecting rod when the energy storage of combined floodgate cam disengages keeps connecting lever the clutch connecting lever is rotated, clutch resets again, and ready for next energy storage, the energy storage indication forwards " not energy storage " position to; This moment, tripping spring was stretched, and the contact pressure spring is compressed, drove main connecting lever action; Close minute auxiliary switch when main shaft is rotated in place, finished by normally closed switching to normally opened contact; Making process finishes.
3) separating brake process:
With reference to figure 8, Fig. 9, Figure 10 and Figure 11, after breaker operating mechanism closes a floodgate, press opening button or the tripping electromagnet pulse got electric, the sincere son of separating brake is pushed, the sincere son of separating brake breaks away from the separating brake connecting lever, the separating brake connecting lever breaks away from the combined floodgate retainer after losing constraint under the effect of self extension spring, make the combined floodgate retainer keep losing efficacy; Main shaft is under the effect of tripping spring and contact pressure spring reset, and to the combined floodgate opposite spin, oil bumper is devoted oneself to work when turning an angle, and the connecting lever that finally closes a floodgate contacts with the separating brake flexible limit, and main shaft stops the rotation; Main shaft when rotation, close a minute indication and forward the separating brake indicating positions to, close minute auxiliary switch and finished resetting of normally closed, normally opened contact, drive simultaneously main connecting lever and move, thus the realization sub-switching operation.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
