As Fig. 2, shown in Figure 3, the support of mechanism is the clamping plate type structure.Support comprises panel 101, base plate 111, intermediate plate 201, connects with 109,2 screw rods of 102,2 screw rods of 5 screw rods 110 between plate, tightens fixing with 202,2 internal thread bars 104 of 103,5 nuts of 14 nuts; 111 positioning tables with positioning sleeve 213 (2), last locating piece 216 (1) and screw rod 102 (5) two ends of panel 101 and base plate guarantee the accurate distance between two plates; 201 of base plate and intermediate plates are with positioning sleeve 204 (3), locating piece 203 (1) guarantees the accurate distance between two plates down.Tighten described nut, internal thread bar fastening after, the distance of three plates between in twos all is fixed in the accurate numerical value of designing requirement, do not need to adjust again any two distances between plates from, can improper distance between plates to occur not bigger from deviation because of adjusting, uneven problem between two plates.Intermediate plate 201 ratio panels, base plate are little, and support is separated into two-layer in the intermediate plate zone, and the zone beyond the intermediate plate is a single layer structure.Internal thread bar 104 and screw rod 109a partly are thicker hexagon (outside base plate), have internal thread to be used for mechanism than far-end from base plate and are connected with installation between the mounting panel.
As Fig. 2, Fig. 3, shown in Figure 4, mechanism has adopted gear/cam associating transmission.Identical active elevating arc 208 and the actuating cam 209 of coaxial usefulness six side's radii fixus directions on mechanism's main shaft 108, actuating cam are roughly the butterfly of symmetry, and four rolling 209a is housed on it.Be fixed with identical driven elevating arc 206 of radial direction and inverted cam 207 with six sides on the output shaft 105, inverted cam is roughly the mountain font of symmetry, and there is the recess of two symmetries the both sides, middle part.Divide, when closing a floodgate, after spring is released and can be made the main shaft quick rotation, the engagement by driving and driven elevating arc between main shaft and the output shaft and the roller 209a of actuating cam on the corresponding recess of inverted cam, roll pushing, realization gear/cam associating transmission.The separating brake course of action that Fig. 4 has drawn gear between described main shaft, output shaft/cam associating transmission moves schematic diagram (referring to the explanation of Fig. 4 in the description of drawings) stage by stage.In the separating brake process, the most of corner of output shaft is finished by gear drive, and gearratio is a fixed value, owing to have only a transmission link and gear drive loss little, transmission efficiency is very high; By cam drive, gearratio is very big during cam drive at separating brake starts and the section of putting in place is very little output shaft corner (respectively having only the several years), in the moment that starts section and the section of putting in place operating spring hour, also can drive the smooth fast motion of output shaft and start to reach and reliably put in place.The startup section shape in the inverted cam two recesses outside, the gearratio that is designed to change, initial gearratio is very big to be reduced gradually again, inverted cam and output shaft are quickened when starting gradually, when equating (or close), the gearratio when the gearratio of cam drive is engaging-in with gear drive is converted to gear drive by cam drive, can start smoothly, greater impact power can when conversion, not occur again.Divide (or closing) when lock puts in place, the two sections short arc surfaces at inverted cam recess both sides 207a, 207b place, arc surface and roller by the actuating cam correspondence are bidirectionally limited, inverted cam, output shaft and switch accurately located, and (or closing) gate position that reliably remains on branch.This gear/cam associating the kind of drive, transmission and positioning accuracy are very high, mechanism's output shaft corner deviation can more easily be controlled at ± 0.5 ° scope in.
As the remainder of Fig. 2, Fig. 3, mechanism driving system shown in Figure 5, stretch out termination outside the base plate at jack shaft 115, be fixed with gear 210 with six sides, this gear and motor output gear 302a and manual gear axle 119 mesh simultaneously.Motor 302 is screwed on base plate, and manual gear axle 119 also is contained on the base plate by the bearing pedestal (in adorn two needle bearings) of lengthening.Jack shaft has been fixed pinion 301 and gear wheel 217 engagements near the panel side with six sides.On six sides of mechanism's main shaft 108 shift fork 214 is housed also.Gear wheel 217 is housed successively and hangs spring connecting lever 219 at the cylindrical part of main shaft near panel, needle bearing 218 is equipped with at both endoporus two ends, on the main shaft of extension spring connecting lever both sides thrust bearing 215 is housed, gear wheel 217 is provided with driving cam 217a and driving cam 217b (being integrated).Between actuating cam 209 and the shift fork 214 positioning sleeve 213 is arranged.Main shaft two ends dress ball bearing is contained on panel and the base plate by bearing pedestal.Hang on the spring connecting lever 219 trundle 220 is housed.The operating spring 223 of mechanism comprises different large, medium and small three springs of diameter, but can not adorn middle or small spring on demand or not adorn one of them.Flange 222 and spring fastening 224 are equipped with in the operating spring two ends.Debug whole nut 221 backs on the pull bar 106 and insert in the hole of flanges and spring fastening, be equipped with between pull bar and spring fastening and reduce friction and guiding self lubrication bearing, adjustment nut 221 is used to adjust the first pressing length and the spring force of operating spring.The pull bar upper end is contained in the wide seam of hanging the spring connecting lever and reaches on the trundle 220.The borehole jack of spring fastening lower end is contained on fulcrum post 130b, the 130a that is fixed on panel, the intermediate plate.Between intermediate plate and base plate, on the locating piece 203 oil bumper 205a and 205b are being housed down, for many rounds become oil extraction cross section formula oil bumper.The oil bumper upper-lower position can be adjusted with the screw thread that following locating piece is connected in the oil bumper lower end, thereby adjusts cushion stroke and damping characteristics.Near the base plate inboard, buffering keeper 211a and 211b are housed on last locating piece 216 in the mechanism upper end, are multilayer rubber cushion bolster.Output shaft 105 is at the middle part of mechanism, and two ends dress ball bearing is contained on base plate and the intermediate plate by bearing pedestal.Six side's output 105a of output shaft stretch out beyond the base plate, are used for being connected between the switch spindle of mechanism and its operation.Embodiment is to be connected sleeve by hexagonal hole the axle coaxial line is directly linked to each other with switch room.
The operation principle of mechanism: during electronic or manual brake separating, motor 302 is switched on or is used the hand-operated tools manual operation, motor output gear 302a and manual gear axle 119 are clockwise rotated, through gear 210, pinion 301, the gear wheel 217 that drives behind the double reduction on the main shaft clockwise rotates, and the driving cam 217a on it rotates simultaneously, promotes trundle 220 (front right-hand member) and hangs spring connecting lever 219 and rotated in the same way by closing position 220b (Fig. 3).Turn to and pull bar 106 (arrival dead point) in line when hanging the spring connecting lever, spring energy-storage reaches maximum, at this moment, one end in contact of trundle 220 left ends and shift fork 214 (in the above-mentioned thermal energy storage process, main shaft is failure to actuate) is rotated further, during trundle and extension spring connecting lever are crossed (crossing the dead point), operating spring 223 rapid release energy by flange 222, adjustment nut 221, pull bar 106, trundle 220, shift fork 214, drive the clockwise quick rotation of main shaft.Between main shaft and output shaft, make output shaft 105 counterclockwise quick rotation separating brakes by aforesaid gear/cam associating transmission.The output shaft corner near 80% before, end in contact on roller 206a of (left side) installing and the piston rod of oil bumper 205a on the driven elevating arc 206, output shaft and switch buffer deceleration steadily arrive the separating brake position.After the output shaft separating brake puts in place, main shaft changes a low-angle (output shaft is motionless) active elevating arc 208 uper side surfaces again and contacts the location with the push rod of buffering keeper 211a, because main shaft still has the effect of the clockwise moment of operating spring, can maintain this separating brake position reliably.When main shaft put in place, trundle 220 was in the separating brake position of 220a.
Driving cam 217b control insurance travel switch SL1 (SL2) on the gear wheel releases the energy fast motion at spring, and after minute (closing) lock cut off the power supply automatically, gear wheel inertia moved when rotating little angle, directly cuts off electric motor loop.Switch S L1, SL2 are inoperative when normal running, two switch short circuits, and mechanism can carry out all normal runnings.Only at the related electric element fault, when motor can not cut off the power supply, switch S L1, SL2 just directly made the motor outage, play the reserve safety effect.Because of main shaft does not significantly impact when putting in place minute (closing), buffering keeper 211a (211b) only has the positioning action that puts in place when minute (closing) lock.Only do not put (before the dead point) in place unexpectedly during sudden power in minute (closing) lock energy storage, effect underdrive pin 220 at operating spring will promote the reposition of gear wheel high speed, and impact is delivered to main shaft, initiatively elevating arc and buffering keeper 211b (211a), the multilayer rubber pad that at this moment cushions keeper 211b (211a) will play the cushioning effect of reserve insurance.Since increased above-mentioned two kinds of insurance parts, when fault that takes place to run into or accident (it is not high that probability takes place), also unlikely damage motor and mechanism element, mechanism can continue operate as normal.
Electric switch-on or closing by hand course of action are identical with separating brake, and just each several part turns to opposite with separating brake.During combined floodgate, be that the roller 206a on mechanism right side has contacted cushioning effect with oil bumper 205b, the buffering keeper 211b on right side plays the positioning action that main shaft puts in place.
As shown in Figure 5, mechanism is equiped with the manual operation interlock, comprise by mounting panel, cushion cover and be screwed in the interlocking electromagnet on the panel 501, manual operation hole plate washer 120, be loaded on the position switch 118 (two position switch SP1, SP2 containing closed assembly) on the panel, be used to control opening of plate washer 120.When having only the state of other all switches in the power station relevant with the switch of this mechanism operation and equipment all to allow this switch and mechanism action, the outside interlock circuit of mechanism could be connected, and the control loop of mechanism and interlocking electromagnet just might be switched on.Have only when satisfying above-mentioned condition and control loop electricity being arranged, rotate interlocking connecting lever 117 and plate washer 120 slightly, switch S P1 moves switching, cut off the electric operating control loop and connect interlocking electromagnet loop (can not carry out electric operating this moment again), interlocking electromagnet energising, the rotation path of plate washer 120 is got out of the way in its 501a adhesive unshakable in one's determination, baffle plate 120 could rotate enough angles, opens the manual operation hole fully and carries out manual operation.When opening the manual operation hole, switch S P2 action, the loop of the interlocking electromagnet that cut-out can only be switched in short-term makes its outage.More than device and conventional electric loop, make between manual operation and electric operating, this switch manually reaches electric operating and the state of related switch and equipment between realized interlocking, can prevent this switch of misoperation.
As shown in Figure 6, when manual branch, closing operation, use handle 604 and one-way shaft 601.One-way shaft is the two ends symmetrical structure, and middle thick part is an overcoat, and interior dress one-way clutch makes its axle can only unidirectionally rotate with respect to overcoat.During manual operation, clockwise rotate the interlocking connecting lever 117 that is screwed in plate washer axle 116 extending panel outer ends, make manual operation hole plate washer 120 rotations of being fixed in the plate washer axle in the panel inboard, open the manual operation hole 101a on the panel, insert one-way shaft, axle six square toes inserting opening pins 602 are prevented from and be fixed in the hexagonal hole of the adapter sleeve 603 on the manual gear axle 119 6 square end heads; Check that the axle that exposes on the one-way shaft turns to turning to of label 601a or 601b indication, should turn to the branch that will carry out of label 121a indication or turning to of closing to conform to, do not conform to and extract one-way shaft out the back of turning around and insert with panel-mounted handle.Again by the indication of two kinds of labels turn to turning handle 604, can realize manual brake separating or the combined floodgate be scheduled to.The plane that one-way shaft puts outward is subjected to handle to turn to label to stop, overcoat can not rotate, and one-way shaft axle and handle can only one-directional rotation when energy storage, hurts sb.'s feelings in operating spring power effect lower handle high speed reverse rotation in the time of can preventing that handle is slipped out of the hand in the thermal energy storage process.
The electric loop of mechanism, except that being connected in series in the electric motor loop increase insurance travel switch SL1, the SL2, all the other are identical with mass-produced other electric spring operation machines, no longer carefully state.
Two section surfaces at present embodiment inverted cam 207 recess both sides 207a, 207b place are short arc surface, but also can be other curved surfaces or plane.Part in the various rotating shafts of present embodiment is used six sides, flat axle or screw respectively, but also can adopt other modes such as flat key, spline, taper bolt, elastic cylindrical pin to fix.
