In conjunction with said structure, the concrete actuating process of the utility model of take is example, and actuating method of the present utility model is described.
Be the structural representation of the utility model initial condition as shown in Figure 1 and Figure 2, under this state, energy storage axle, ground connection power shaft 11 be not operation all, the roller 22 of output toggle arm 20 is positioned at the corner position 903 of curve disc 9 shaped grooves 901, and the pin 23 of ground connection output 12 is positioned at an end of mounting panel 1 arc groove 10 and the opening part of curve disc 9 straight-line grooves 902 simultaneously.When breaker operation mechanism carries out closing operation, as shown in Figure 3, Figure 4, by external impetus mechanism controls energy storage axle, rotated, the energy storage axle drives 19 pairs of combined floodgate energy-stored springs of combined floodgate connecting lever 18 and carries out energy storage, when energy storage puts in place, the cam 2 connected by combined floodgate semiaxis 5,4 pairs of energy storage axles of combined floodgate buckle carries out spacing, namely the combined floodgate energy storage state is kept.As shown in Figure 5, Figure 6, when combined floodgate semiaxis 5 is threaded off with combined floodgate buckle 4, state lifts restrictions between combined floodgate buckle 4 and cam 2, by combined floodgate energy-stored spring 18, released energy, drive combined floodgate connecting lever 19, energy storage axle, cam 2 rotations, cam 2 drives transmission crank arm 3 and rotates, and transmission crank arm 3 drives output toggle arm 20, separating brake connecting lever 21 rotates.On the one hand, pull separating brake energy-stored spring 6 to carry out energy storage by separating brake connecting lever 21, when energy storage puts in place, by separating brake buckle 7,8 pairs of transmission crank arm of separating brake semiaxis 3, undertaken spacingly, keep the separating brake energy storage state; On the other hand, roller 22 by output toggle arm 20 drives curve disc 9 rotations, until roller 22 reaches curve disc 9 shaped groove 901 1 ends, when curve disc 9 is rotated, after curve disc 9 cards and mounting panel 1 arc groove 10 are overlapping, form position, hole 1001 at arc groove 10 1 ends, the pin 23 that ground connection output 12 connects is limited in this position, hole 1001, because pin 23 can't move, therefore the action of ground connection output 12 is limited, the ground connection operating mechanism can't move.This process is that breaker operation mechanism is realized closing a floodgate, and the rear and ground connection operating mechanism realization interlocking that puts in place that closes a floodgate.
As shown in Figure 7, Figure 8, when breaker operation mechanism completes closing operation, rotated by external impetus mechanism controls energy storage axle, realize the stored energy operation of combined floodgate energy-stored spring 18, this operation is in order to realize breaker operation mechanism rapid closing next time.Under Fig. 7, state shown in Figure 8, when separating brake buckle 7 was threaded off with separating brake semiaxis 8, transmission crank arm 3 was threaded off with separating brake buckle 7, under the effect of separating brake energy-stored spring 6, realize quick acting switching-off, breaker operation mechanism and ground connection operating mechanism will be reset to Fig. 1, state shown in Figure 2.As shown in Figure 9, Figure 10, under initial condition, by external impetus mechanism controls ground connection power shaft 11, rotated, ground connection power shaft 11 drives ground connection output 12 and rotates, ground connection output 12 will first compress ground spring 16, after ground connection output 12 turns over an angle, the rolling seat 14 of spring pole socket 15 will slide into the other end by an end of ground connection output 12 1 side arc chutes 1201, and be rotated further by the potential energy promotion ground connection output 12 of ground spring 16, until ground connection output 12 opposite sides and locating part 13 offset spacing.In this process, the pin 23 that ground connection output 12 connects slides into the other end by arc groove 10 1 ends, simultaneously, because pin under initial condition 23 is positioned at curve disc 9 straight-line groove 902 aperture positions, when pin 23 is done circular motion, pin 23 is by the straight-line groove of arrival curve dish 9 902, and drive curve disc 9 is rotated.When pin 23 slides into the other end by arc groove 10 1 ends, curve disc 9 stops operating, and now, and the other end of curve disc 9 shaped grooves 901 is just spacing with the formation that offsets of the roller 22 of output toggle arm 20, therefore output toggle arm 20 can't rotate, can't the operating breaker operating mechanism.When needs carry out separating brake to the ground connection operating mechanism, only need reverse operating ground connection power shaft 11, can be reset to Fig. 1, state shown in Figure 2.
Above structure and actuating mode are intended to illustrate technological means of the present utility model, and unrestricted technical scope of the present utility model.Those skilled in the art do apparent improvement in conjunction with existing common practise to the utility model, within should belonging to the scope that the utility model protects.
