nullDuring combined floodgate，Rotate energy storage gear shaft 24，The gear of energy storage gear shaft 24 drives energy storage gear 20 to rotate by the engagement between gear，Now energy storage interlocking shaft 21 transfixion，When the stop end finger 25 on energy storage gear 20 forwards the breach 261 of rotation dish 26 to，Stop end finger 25 props up breach 261，Make rotation dish 26 rotate and drive energy storage gear shaft 21 to rotate，Drive spring anchor block 221 to carry out elastic component 41 stretching energy storage with the fixing swing arm 22 being connected of energy storage gear shaft 21 simultaneously，When pulley 27 touches energy storage end finger 23 one end，Energy storage end finger 23 is promoted to rotate，The other end making energy storage end finger 23 props up combined floodgate interlocking shaft 32，So that energy storage end finger 23 stops pulley 27 to move on，Stop energy storage interlocking shaft 21 to rotate simultaneously，Now switching-on mechanism 3 completes energy storage action，The ratchet 72 of stop mechanism 7 props up the gear of energy storage gear shaft 21，Prevent from occurring the phenomenon of rollback under the counteracting force of elastic component 41.When pressing the button 63 of switch knob 6, button 63 pushing rolling wheels 61 rotates, promote gangbar 62 simultaneously, combined floodgate interlocking shaft 32 is rotated, when combined floodgate interlocking shaft 32 turns to certain position, combined floodgate interlocking shaft 32 releases the obstruction to energy storage end finger 23, energy storage end finger 23 rotates under the counteracting force of elastic component 31 and sees Fig. 7 by groove 321(), energy storage end finger 23 releases the obstruction to pulley 27 simultaneously, elastic component 31 releases energy under counteracting force, swing arm 22 is driven to rotate and then drive energy storage interlocking shaft 21 to rotate, when the release of elastic component 31 energy is complete, feed motion completes.nullRelease energy drive energy storage interlocking shaft 21 simultaneously rotationally at elastic component 31，The cam 26 being fixedly mounted on energy storage interlocking shaft 21 is driven to rotate，The roller 341 of pitman shaft 34 abuts with the curved surface 281 at the contour line place of cam 26，When cam 26 turns to rise part，Curved surface 281 pushing rolling wheels 341 makes pitman shaft 34 rotate，Pitman shaft 34 promotes connecting rod 36 to rotate and then pull switch rotating shaft 33 rotates，The rotation of switch shaft 33 drives stick 43 to move，Elastic component 41 is compressed energy storage simultaneously，The (see figure 8) when the ends contact of pitman shaft 34 is to the end 422 of separating brake end finger 42，Separating brake end finger 42 is promoted to rotate，When the end 421 that cam 26 moves to rise maximum and separating brake end finger 42 touches separating brake axle 44，Separating brake axle 44 stops separating brake end finger 42 to rotate，Cam 26 stops operating simultaneously，Elastic component 41 completes compressed energy-storage.When carrying out separating brake energy storage, switch shaft 33 promotes connecting rod 92 and then promotes connecting rod 91, and connecting rod 91 drives the axis of rotation of signal receiver 93, signal receiver 93 to record divide-shut brake signal, and what switching-on mechanism 3 completed simultaneously completes the energy storage to brake separating mechanism 4.
During separating brake, when separating brake switchs 45 acquisition sub-gate signal, separating brake switchs 45 pushing rolling wheels 441 and rotates, promote gangbar 442 simultaneously, separating brake axle 44 is rotated, when separating brake axle 44 turns to certain position, separating brake axle 44 releases the obstruction to separating brake end finger 42, separating brake end finger 42 rotates and by groove 443 under the counteracting force of elastic component 41, separating brake end finger 42 releases the obstruction to pitman shaft 34 simultaneously, elastic component 41 releases energy under counteracting force, switch shaft 33 is driven to rotate, switch shaft 33 recovers initial position by connecting rod 36 drivening rod axle 34, Simultaneous Switching rotating shaft 33 drives stick 43 to return to initial position, now elastic component 41 energy release is complete, complete separating brake action.
Due to relatively independent between switching-on mechanism 3 and brake separating mechanism 4, after switching-on mechanism completes feed motion, directly the energy storage gear shaft 24 of stored energy mechanism 2 can be carried out motor and drive energy storage or manual energy storage, the drawback that cannot complete secondary combined floodgate in time that can effectively solve to need to carry out being about the combined floodgate accumulation of energy of 30 seconds when general pull operation mechanism secondary separating brake occurs after first time separating brake, combined floodgate and cause, after effective solving to break down at equipment, having a power failure, the problem of the equipment damage that pull operation mechanism cannot carry out divide-shut brake action timely and bring.
Finally it is emphasized that this utility model is not limited to above-mentioned embodiment, the change such as change such as the type of drive of energy storage gear shaft also should include in this utility model scope of the claims.
