Slided into groove 15, when upper disconnecting switch completion separating brake, lower disconnecting switch is in closing position or lower disconnecting switch is completed to close a floodgate
And upper disconnecting switch, when being in open position, sheave A9 radial slot notch face sheave B7 radial slot notch is (such as Fig. 3 institutes
Show).
The gear A 5 is fixedly mounted on rotating shaft B13, and gear B 6 is fixedly mounted in rotating shaft C 14, and rotating shaft C 14 is rotatable
Ground is arranged on front plate 4 and rear plate 2, and gear B 6 engages with gear A 5, and the rotating shaft A12 connects with upper disconnecting switch rotating shaft
Connect or coaxial with upper disconnecting switch rotating shaft, rotating shaft C 14 is connected or coaxial with lower disconnecting switch rotating shaft with lower disconnecting switch rotating shaft.
Five angles of the forward and backward clamping plate of operating mechanism are fastened on switch element body 16 with bolt during use, and will be turned
Axle A12 is connected with upper disconnecting switch rotating shaft, and rotating shaft C 14 is connected with lower disconnecting switch rotating shaft, or sheave A9 is directly installed on
In disconnecting switch rotating shaft, gear B 6 is directly installed in lower disconnecting switch rotating shaft, and the structure after assembling is as shown in Figure 5.
The course of work of the present utility model is as follows：
(1) sub-switching operation
According to the separating brake order of regulation, during separating brake, first divide disconnecting switch, during upper disconnecting switch separating brake, under every
Leave pass akinesia, upper disconnecting switch separating brake in place after, then divide lower disconnecting switch, during lower disconnecting switch separating brake, on
Disconnecting switch should be in open position transfixion all the time.
Fig. 2 show upper and lower disconnecting switch and is in closing position.Sheave A9 is fixed on rotating shaft A12, and sheave B7 is affixed
On rotating shaft B13, before sub-switching operation, at the notch for the radial slot 15 that the straight pin 11 on driving lever 10 is located at sheave A9.Counterclockwise
Driving lever 10 is rotated, the straight pin 11 on driving lever 10 enters in sheave A9 radial slot 15, drives sheave A9 to rotate clockwise,
Upper disconnecting switch is gradually opened from closing position, and when driving lever 10 rotates 45 ° to position shown in Fig. 3, upper disconnecting switch is completed
The notch of separating brake, now the notch face sheave B7 of sheave A9 radial slot 15 radial slot 15, sheave B7 in whole process
Interior concaved circular cambered surface is blocked by the outer convex arc surface of selenodont disk 1, therefore sheave B7 transfixions, therefore lower disconnecting switch is static not
It is dynamic.Continue to rotate counterclockwise driving lever 10, the straight pin 11 on driving lever 10 enters in sheave B7 radial slot 15, drives sheave
B7 is rotated clockwise, and gear A 5 rotates with sheave B7, while drives gear B 6 to rotate counterclockwise, because rotating shaft C 14 is with
Disconnecting switch rotating shaft connection or coaxial with lower disconnecting switch rotating shaft, therefore, when gear B 6 rotates counterclockwise, lower isolator operation axle
Also rotate counterclockwise simultaneously and lower disconnecting switch is gradually opened from closing position.When driving lever 10 rotates 45 ° to position shown in Fig. 4
When putting, lower disconnecting switch completes separating brake.Sheave A9 interior concaved circular cambered surface is by the outer convex arc surface of selenodont disk 1 in whole process
Block, therefore sheave A9 transfixions, therefore upper disconnecting switch is in gate-dividing state transfixion all the time.
(2) closing operation
It should first close lower disconnecting switch according to the order of regulation, during combined floodgate, in lower disconnecting switch making process, upper disconnecting switch
Akinesia, after lower disconnecting switch in-place closing, then disconnecting switch is closed, in upper disconnecting switch making process, lower disconnecting switch
"on" position transfixion should be in all the time.
Fig. 4 show upper and lower disconnecting switch and is in open position.Straight pin 11 on driving lever 10 is in sheave B7 footpath
Into groove 15, when rotating clockwise driving lever 10, straight pin 11 thereon drives sheave B7 to rotate counterclockwise, while drive and groove
Gear A 5 coaxial wheel B7 rotates counterclockwise, and gear A 5 drives gear B 6 to rotate clockwise again, because rotating shaft C 14 is isolated with
Switch shaft connection or coaxial with lower disconnecting switch rotating shaft, therefore, when gear B 6 rotates clockwise, lower isolator operation axle is also same
When rotate clockwise, make lower disconnecting switch towards combined floodgate direction move.When driving lever 10 rotates 45 ° to position shown in Fig. 3,
Lower disconnecting switch is completed to close a floodgate, the straight pin 11 on driving lever 10 just at the notch of sheave A9 radial slot 15 at, entirely
During sheave A9 interior concaved circular cambered surface blocked by the outer convex arc surface of driving lever 10, therefore sheave A9 transfixions, thus on every
Leave pass also transfixion.Continue to rotate clockwise driving lever 10, the straight pin 11 on driving lever 10 enters sheave A9 radial direction
In groove 15, sheave A9 is driven to rotate counterclockwise, upper disconnecting switch is moved towards the direction of combined floodgate, is arrived when driving lever 10 rotates 45 °
Shown in Fig. 2 during position, upper disconnecting switch is completed to close a floodgate.Sheave B7 interior concaved circular cambered surface is by selenodont disk 1 in whole process
Outer convex arc surface block, therefore sheave B7 transfixions, therefore lower disconnecting switch also transfixion.
Described above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to
