Similarly right redundant switch can also be obtained turning right the state of arm 16 by the state of seven-link assembly 56, and according to turn left arm 6 with
And the state for arm 16 of turning right controls respective auxiliary switch and then control left and right motor to work, to carry out to energy-stored spring in advance
Energy storage.
The left closing pawl 37 is rotatably connected in left installing rack 33, and the right switching-on sincere sub 44 is rotatably connected on right peace
Shelve on 34, and the left closing pawl 37 and sincere sub 44 shape of right switching-on are V-arrangement.And the left closing pawl 37 with
And it is equipped with back-moving spring in right switching-on sincere sub 44.
The left separating brake semiaxis 11 or right separating brake semiaxis 21 are provided with connecting plate 57, and the frame 1, which is provided with, to be used to push away
Dynamic connecting plate 57 and then the 3rd actuating unit 58 for driving left separating brake semiaxis 11 or right separating brake semiaxis 21 to rotate.
First actuating unit 40, the second actuating unit 47 and the 3rd actuating unit 58 are the group of coil and iron core
Close, by being moved along a straight line to coil electricity band dynamic iron core.
The present invention operation principle be：Left motor 31 drives left switching-on input shaft 2 to rotate, so drive left cam 4 and
Left-hand rotation square connecting lever 42 is rotated together, while the energy-stored spring that can also elongate in left spring stored energy mechanism 5 carries out energy storage, works as left spring
The 5th projection 43 that energy-stored spring in stored energy mechanism 5 is elongated on a timing, left-hand rotation square connecting lever 42 can encounter left travel switch
41, and then circuit is disconnected, left motor 31 stops operating, and now the son 35 that rolls left on left cam 4 is by left closing pawl
37 are blocked, and left closing pawl 37 is blocked by left floodgate semiaxis 38, i.e., now left cam 4 be can not spring force work
With lower rotation, the state of energy storage in advance is completed；
When the left side needs to close a floodgate, the first actuating unit 40 of control works, and pushes right baffle-plate 39, forces left 38 turns of floodgate semiaxis
Dynamic, and then cause left floodgate semiaxis 38 from blocking left closing pawl 37, then now left closing pawl 37 cannot be blocked and rolled left
Son 35, the energy-stored spring of so left energy-stored spring mechanism 5 can release energy, and force left cam 4 to rotate to push and turn left the first of arm 6
Projection 7, so that "on" position is reached, while arm 6 of turning left can compress left tripping spring 25 when rotating carry out energy storage, and arm 6 of turning left
When reaching closing position, the on arm 6 second projection 9 of turning left can be blocked by a left side sincere sub 8, a left side sincere sub 8 and left combined floodgate holding rod 10 1
Rise and blocked by separating brake semiaxis 11, so that arm 6 of turning left keeps "on" position.
When needing separating brake, the 3rd actuating unit 58 of control works, and pushes connecting plate 57, forces right separating brake semiaxis 21 to rotate,
Because being linked between left separating brake semiaxis 11 and right separating brake semiaxis 21 by third connecting rod 22, left separating brake semiaxis 11 is also simultaneously
Rotate, and then cause left separating brake semiaxis 11 from blocking left combined floodgate holding rod 10, and then cause the left side on left combined floodgate holding rod 10
Sincere sub 8 can not block the second projection 9 turned left on arm 6, so in the presence of left tripping spring 25, force arm 6 of turning left to rotate
Reach gate-dividing state.
Similarly, the operation principle of the right separating brake and combined floodgate is similar with the left side.
In this way, when left is closed a floodgate, right wing is in energy storage state, i.e., right wing closes a floodgate immediately after left separating brake, together
Reason, when right wing closes a floodgate, left is in energy storage state immediately, can so greatly shorten the switching time of two-way.
