One end of described connecting lever 15 and A road drive stay 13 flexibly connect and are meant to have long lumbar hole 17 on the connecting lever 15, have finger 16 on the A road drive stay 13, and described finger 16 is slidingly fitted in the long lumbar hole 17 and is rotatably assorted simultaneously in long lumbar hole 17.
Described second interlock comprises B road drive stay 7, A road divide-shut brake axle 8, A road divide-shut brake handwheel 9, rotating disk 21 and connecting rod 12; Described A road divide-shut brake axle 8 is rotatably connected on the pedestal 6; And an end is connected with A road divide-shut brake handwheel 9; One end of the other end and B road drive stay 7 offsets or breaks away from, and the other end of B road drive stay 7 is slidingly connected on the pedestal 6 also spacing through rotating disk 21.Described rotating disk 21 is fixedly connected with an end of connecting rod 12 through disk shaft 20, and disk shaft 20 is rotatably connected on the pedestal 6, and the other end of connecting rod 12 is fixedly connected with disconnecting link rotating shaft 5.
Described B road drive stay 7 has open slot 22 through rotating disk 21 spacing being meant on the described rotating disk 21, and an end of B road drive stay 7 stretches in the open slot 22 or breaks away from.
Described the 3rd interlock comprises A road pin 24, A road guide vane end stop 25, B road pin 26 and B road guide vane end stop 23.Described A road pin 24 is vertically connected on the A road drive stay 13, and B road guide vane end stop 23 is fixedly connected on the B road divide-shut brake axle 11, and described A road pin 24 offsets with B road guide vane end stop 23 or throws off; Described B road pin 26 is vertically connected on the B road drive stay 7, and A road guide vane end stop 25 is fixedly connected on the A road divide-shut brake axle 8, and described B road pin 26 offsets with A road guide vane end stop 25 or throws off.
The present invention is applicable to the industrial and mining enterprises of two road inlet wires, when one road inlet wire closes a floodgate, and the use of can't closing a floodgate of another road inlet wire.As, when A road inlet wire was supplied power, promptly disconnecting link 3 was in "on" position, vacuum interrupter conducting in the A road post assembly 1, and power supply arrives outlet post assembly 4 in order to power supply from the A end.B road post assembly can't make disconnecting link 3 close a floodgate under this state, and 3 of disconnecting links can't be opened.Behind the separating brake of A road, and disconnecting link 3 is when closing a floodgate, and just can close a floodgate in the B road, after closing a floodgate in the B road, and vacuum interrupter conducting in the B road post assembly 2, power supply arrives post assembly 4 in order to power supply from the B end, and this moment can't close a floodgate in the A road, and disconnecting link 3 also can't be opened.And have only when A road and B road all during separating brake, disconnecting link 3 just can be opened, and when in other words on outlet post assembly 4, not having electricity, can open disconnecting link 3.
Like Fig. 4 and shown in Figure 5; When close a floodgate in the A road; Connecting lever 15 and A road drive stay 13 in vertical state, finger 16 is positioned at the upper end of long lumbar hole 17, block 18 offsets spacing with the spacing connecting lever 19 of disconnecting link; Disconnecting link rotating shaft 5 can't the counter clockwise direction (being the separating brake direction) in shown in Figure 5 be rotated, thereby guarantee that disconnecting link 3 can't separating brake.When the separating brake of A road, right-hand move of A road drive stay 13 in shown in Figure 4 drives finger 16 and moves to right-hand; Finger 16 not only was slidingly matched with long lumbar hole 17 but also was rotatably assorted with long lumbar hole 17 this moment; Because block 18 links to each other with connecting lever 15 through block rotating shaft 14, so the left-hand rotation of block 18 in shown in Figure 4, until the restriction of leaving the spacing connecting lever 19 of disconnecting link fully; At this moment, disconnecting link rotating shaft 5 does not receive the restriction of block 18.
Like Fig. 6, Fig. 7 and shown in Figure 8; When close a floodgate in the B road, an end of B road drive stay 7 inserts in the open slot 22 on the rotating disk 21, and rotating disk 21 can't be rotated; The connecting rod 12 that links to each other with rotating disk 21 through disk shaft 20 also can't rotate, thereby disconnecting link rotating shaft 5 also can't be rotated.When the separating brake of B road; One end of B road drive stay 7 leaves the open slot 22 on the rotating disk 21; This moment, rotating disk 21 can not rotated by the restriction of B road drive stay 7, thereby can rotate through disk shaft 20 drivening rods 12 yet, and disconnecting link rotating shaft this moment 5 can not rotated by the restriction of B road drive stay 7.
Therefore, in sum, have only when A road and B road all during separating brake, disconnecting link rotating shaft 5 does not just receive the restriction of A road drive stay 13 and B road drive stay 7 can realize rotating, and disconnecting link 3 just can be opened.
Like Fig. 9 and shown in Figure 10; When close a floodgate in the A road; A road pin 24 on the A road drive stay 13 is butted on the lower right corner shown in Fig. 9 of B road guide vane end stop 23, and at this moment, B road guide vane end stop 23 receives the restriction of A road pin 24 and can't rotate to the clockwise direction shown in Fig. 9; Be that B road divide-shut brake axle 8 can't rotate to clockwise direction (direction of promptly closing a floodgate), thereby can't close a floodgate in assurance B road.But this moment, B road guide vane end stop 23 can be to the counter clockwise direction shown in Fig. 9 (being the separating brake direction) rotation, and promptly the B road can separating brake.When A road drive stay 13 drives A road pins 24 when the left shown in Figure 10 moves, A road pin 24 is thrown off with B road guide vane end stop 23 fully, and B road guide vane end stop 23 does not receive the restriction of A road pin 24 at this moment; Both can rotate to clockwise direction; Also can be to rotation counterclockwise, therefore, B road divide-shut brake axle 8 can two-wayly rotate; In other words, can close a floodgate also can separating brake on the B road.
In like manner; Like Figure 11 and shown in Figure 12, when close a floodgate in the B road, the B road pin 26 on the B road drive stay 7 is butted on the lower right corner shown in Figure 11 of A road guide vane end stop 25; At this moment; A road guide vane end stop 25 receives the restriction of B road pin 26 and can't rotate to the clockwise direction shown in Figure 11, and promptly A road divide-shut brake axle 11 can't rotate to clockwise direction (direction of promptly closing a floodgate), thereby can't close a floodgate in assurance A road.But this moment, A road guide vane end stop 25 can be to the counter clockwise direction shown in Figure 11 (being the separating brake direction) rotation, and promptly the A road can separating brake.When B road drive stay 7 drives B road pins 26 when the left shown in Figure 12 moves, B road pin 26 is thrown off with A road guide vane end stop 25 fully, and A road guide vane end stop 25 does not receive the restriction of B road pin 26 at this moment; Both can rotate to clockwise direction; Also can be to rotation counterclockwise, therefore, A road divide-shut brake axle 11 can two-wayly rotate; In other words, can close a floodgate also can separating brake on the A road.
