It does not influence mutually, can both start detecting system and driving motor action is made to realize switch divide-shut brake, it can also be by revolving manually
Turn operation handle and realizes switch divide-shut brake.
Since floating disc 12 and yoke frame 13 are coordinated by boss and raised pushing tow, realize that floating disc divides with fixed disk 14
From, in this way, when clutch is in discrete state, it is floating only after driving wheel 11 drives floating disc 12 first to turn an angle
Moving plate 12 can just realize that transmission cooperation, clutch can just realize engagement with fixed disk 14, that is to say, that start to rotate in driving wheel
When, only driving wheel 11 first turns an angle so that the boss on floating disc is staggered after the protrusion on yoke frame 13, floats
Disk 12 can drive operating shaft to rotate after being clamped with fixed disk 14, and therefore, the rotation of operating shaft 8 can lag behind driving wheel 11.It is main
It is symmetrical arranged on driving wheel 11 there are two positioning bolt 21, after driving wheel 11 drives floating disc 12 to rotate 180 °, detecting system is just
Driving motor 3 can be controlled to be stopped, when driving wheel 11 drives floating disc to rotate 180 °, since operating shaft rotational hysteresis is in master
Driving wheel, the rotational angle of operating shaft 8 is less than 180 °, for on-load switch, from open position to closing position or from point
Gate position is to closing position, it is only necessary to which operating shaft rotates 90 ° and switching on and off action can be completed, this is just determined from open position
To closing position, or from open position to closing position, operating shaft 8 must be rested on apart from the position of the upper 90 ° of corners in a position
Place.Therefore, in the present embodiment, uniform intervals are provided with four pairs of conductive contact blades 19 in inductive disks, that is to say, that from open position
To closing position, or from open position to closing position, the contact 9 in operating shaft 8 often rotates 90 ° and will be touched with corresponding conduction
The conductive cooperation of piece 19, while controller controls motor stalls, and on-load switch is made to be maintained at open position or combined floodgate
Position needs to restart driving motor when needing to be again started up.In the present embodiment, conductive contact blade 19 is along inductive disks
The arc-shaped flaky structure of circumferentially extending, in this way when contact and conductive contact blade coordinate, can allow for contact in the circumferential has centainly
Fault-tolerant surplus, and then improve conductive contact blade and contact cooperation precision.Operating mechanism in the utility model is sealed-box type
Structure, can achieve the effect that moisture-proof, dust-proof, adapt to severe working environment.
The operation principle of the utility model operating mechanism:In use, the operating shaft and on-load switch of the motor-operating mechanism
Moving contact structure be sequentially connected, and then drive on-load switch divide-shut brake.It is in open position in on-load switch(Or closing position
It sets)When, driving motor is in stop state, and the boss on floating disc 12 is in pushing tow cooperation shape with the protrusion on yoke frame 13
State, floating disc 12 are in disengaged position with fixed disk 14, and operating shaft 8 can both be manually operated at this time and realized that on-load switch closes a floodgate,
The electronic 3 actuating on-load switch of driving can also be started to close a floodgate.When need carry out closing operation(Or sub-switching operation)When, controller control
Driving motor 3 processed rotates, and driving wheel 11 drives floating disc 12 to rotate, and the boss on floating disc 12 and the protrusion on yoke frame 13 are wrong
It opens, under the elastic force effect of spring 16, floating disc 12 is automatically close to fixed disk 14 so that floating disc 12 is matched with the fixed transmission of disk 14
It closes, and then fixed disk and operating shaft 8 is driven to rotate.Driving wheel 11 drives floating disc to rotate 180 °, boss on floating disc 12 and
Pushing tow coordinates protrusion on yoke frame 13 again, and floating disc 12 is detached from fixed disk 14, while sensing positioning spiral shell close to switch 4
21 position of bolt, controller control driving motor 3 and stall, and on-load switch realizes closing operation.
In the other embodiments of the utility model, driving wheel and motor output gear may be replaced by sprocket wheel or other
Drive mechanism.
In the other embodiments of the utility model, CONTACT WITH FRICTION can also be passed through between the floating disc of clutch and fixed disk
The mode of cooperation realizes drive connection.
It, can be big according to rotational angle needed for operating shaft when on-load switch divide-shut brake in the other embodiments of the utility model
