To braking brake, this brake modes are fricton-tight instant brakes；
When electromagnet 13-1 obtains electric, electromagnetic force pulls the main shaft and compression electromagnet spring 13-2 of electromagnet 13-1, electricity
Magnet 13-1 pulls torque arm 12-10 that torque arm axle sleeve 12-3 and semiaxis 12-7 is driven to be rotated by 90 ° by connecting plate 12-8, boss 12-
4 contact with the limiting stand 12-5 on brake axle sleeve 12 and are limited, while semiaxis 12-7 is screwed out out of arch groove 12-1, to release
Brake.
It further, as shown in figures 9 and 11, further include manual-operating mechanism and clutch；
The manual-operating mechanism includes grasping the correspondence of jack 3 by hand to insert in the operation bar jack being arranged in central axis 18
External operation handle in 18-1, external manipulator's sleeve are being set in operation bar jack 18-1 on the fang platform 18-2 of bottom；
The clutch includes the clutch control lever shaft 33 being mounted in 15 axis hole of handle bracket, passes through handle axle sleeve 7-1
The handle 7 being fixedly connected with clutch control lever shaft 33 is mounted on the cam 34 at the middle part of clutch control lever shaft 33, by two 36-1 of pin with
The yoke bar 36 that handle bracket 15 connects, the shift fork 35 being fixedly connected with yoke bar 36；
18 upper end of central axis is sliding combined with disk 20 on clutch, installs clutch lower wall 22-1 in the middle part of central axis 18, from
Driven bevel gear 22 is fixed on clutch lower wall 22-1, driven bevel gear 22 is engaged with the master for being connected to 10 output shaft of gearbox
Bevel gear 21 is moved, is set on central axis 18 between the clutch-pressing spring on clutch between disk 20 and center bracing strut 14
20-1。
By the extruding of clutch-pressing spring 20-1, the clutch pawl of the clutch pawl of disk 20 and clutch lower wall 22-1 on clutch
Engagement, the power of motor 11 by the deceleration and the active bevel gear 21 by being installed on output shaft of gearbox 10 be transmitted to from
Dynamic bevel gear 22, driven bevel gear 22 by disk 20 on the clutch lower wall 22-1 of installation fixed thereto, clutch and
The cooperation of spline 19-1 and spline 19 transfers power on central axis 18 in disk 20 on clutch, then is passed through by central axis 18
The 31 sliding tooth batten 16 of cam fluted disc of installation fixed thereto moves.
Under electric model, handle 7 pushes the electrical position and and limiting block of Sign Board by the slide opening 6 on cover board 2
Two 15-2 contact, handle 7 are in monostable, while the outside of the minimum centers-distance of cam 34 by the effect of handle tension spring 7-4
The upper plane contact of face and yoke bar 36 does not give yoke bar 36 active force, and the shift fork 35 connecting with yoke bar 36 occupy clutch
The middle part of upper disk 20 does not give disk 20 on clutch yet and applies active force, extruding of the disk 20 by clutch-pressing spring 20-1 on clutch
It is engaged with clutch lower wall 22-1, is transmitted to power in divide-shut brake executing agency from motor 11.
When handle 7 is in manual mode, clutch is separated, and clutch lower wall 22-1 and driven bevel gear 22 are at center
It dallies on axis 18, external operation handle is grasped in the operation bar jack 18-1 being arranged in the insertion central axis 18 of jack 3 and covered by hand

It is connected to balance pivot with handle bracket 15, using lever principle using two 36-1 of pin being arranged on yoke bar 36 as fulcrum band
Disk 20 on clutch is pushed away clutch lower wall 22-1 and realizes clutch separation by dynamic shift fork 35.
Further, as shown in Figure 10,18 lower part of central axis is pacified between driven bevel gear 22 and center bearing bracket 14
Equipped with plate bearing 32；Plate bearing 32 is used to be isolated the friction of driven 22 centering arbor support 14 of bevel gear, central axis 18
Upper clutch-pressing spring 20-1 squeezes disk 20 on clutch, and disk 20 squeezes clutch lower wall 22-1, clutch lower wall 22- on clutch
1 is fixed with driven bevel gear 22, and pressure is transmitted to driven bevel gear 22, if without plate bearing 32, clutch-pressing spring 20-
1 directly generates centering arbor support 14 friction.There is no the isolation of plate bearing 32, not only increase frictional resistance, will also generate
Frictional noise.
As shown in figure 11,18 top of central axis is equipped with friction between clutch-pressing spring 20-1 and center bearing bracket 14
Ring 20-3.Drag ring 20-3 is identical as the effect of plate bearing 32, to be isolated, reduce clutch-pressing spring 20-1 and center bearing bracket 14
Between friction.It is low speed at this, the occasion infrequently moved, drag ring 20-3 can replace the effect of bearing.
Further, as shown in figure 9, the upper plane contact of 34 downside of the cam and yoke bar 36.Handle 7 passes through handle
Axle sleeve 7-1 is fixedly connected with clutch control lever shaft 33, and cam 34 is fixedly connected with clutch control lever shaft 33, when clutch engagement, cam
34 minimum diameter of axle cam surface is contacted with yoke bar 36, when handle is rotated by 90 ° counterclockwise, the maximum diameter of axle cam of cam 34
Push yoke bar 36 open realization clutch separation in face.
Further, as shown in figure 11, the shift fork 35 is placed in the land 20-2 groove being arranged in the middle part of disk 20 on clutch.
The land 20-2 being arranged on disk 20 on clutch is stirred on 35 head of shift fork, realize clutch separation with engage.
Further, the inner periphery that the outer circumference surface of 18 upper end of central axis passes through disk 20 on setting spline 19 and clutch
The spline 19-1 of face setting is slidably matched.Realize clutch lower wall 22- of the driven bevel gear 22 by installation fixed thereto
1, the cooperation of spline 19-1 and spline 19 transfers power to central axis 18 in disk 20 on disk 20 and clutch on clutch
On, then moved by the 31 sliding tooth batten 16 of cam fluted disc of installation fixed thereto by central axis 18.
Further, as shown in figure 9, the handle bracket 15 is fixedly connected with the limit being limited to handle 7 within the scope of 90 degree
Position gear one 15-1 and two 15-2 of limiting block.Handle 7 is fixedly connected by handle axle sleeve 7-1 with clutch control lever shaft 33, cam 34 and
Clutch control lever shaft 33 is fixedly connected, and when clutch engagement, the minimum diameter of axle cam surface of cam 34 is contacted with yoke bar 36, works as handle
When being rotated by 90 ° counterclockwise, the maximum diameter of axle cam surface of cam 34 pushes yoke bar 36 open realization clutch separation.
As depicted in figs. 1 and 2, for this circuit breaker operation mechanism in assembly, cover board 2 passes through cover board connecting hole 1-2 with bolt
Connect with the bolt hole 2-1 on shell 1, be provided on cover board 2 hand behaviour jack 3, observation window 4, Sign Board 5, slide opening 6 and for
The connecting hole 8 of breaker connection.This circuit breaker operation mechanism button is on-board the circuit breaker and fixed, it is then logical with external electric-control system
It can be used after electricity.
The working principle of this circuit breaker operation mechanism is as follows：
