Application examples
A kind of permanent-magnet breaker emergency brake-dividing device, as shown in Figure 1 to Figure 3, as shown in Figures 1 to 4, it includes rotating bar
1st, operation handle 2, power transmission shaft 3, fixed block 4, cam 5, reduction torsion spring 6, power transmission shaft 3, connecting lever 7 and handle locking mechanism, it is described
Rotating bar 1 is rotatably provided in switch cubicle 8, and (note is set along the movable direction of permanent-magnet breaker 9:The permanent-magnet breaker 9
It is removably set in the switch cubicle 8, is changed by mobile between testing position and operating position), the operation handle 2
It is rotatably provided on the front panel 81 of the switch cubicle 8, it is connected with one end of the rotating bar 1, the handle locking machine
Structure is arranged on outside the front panel 81 of the switch cubicle 8, for being locked to the position of operation handle 2, in the present embodiment
Handle locking mechanism uses the handle locking mechanism described in embodiment 1, and being set with the rotating bar 1 can be along the rotating bar
1 axial movement but the sleeve pipe 10 that can not be rotated relative to the rotating bar 1, the cam 5, which is welded or riveted, is fixed on the set
Outside pipe 10, the fixed block 4 is fixed on the permanent-magnet breaker 9 and by sets of holes thereon and the movable sleeve of described sleeve pipe 10
Connect, the fixed block 4 can be rotated relative to described sleeve pipe 10 but can not moved axially in described sleeve pipe 10 along sleeve pipe 10, described
The tube of reduction torsion spring 6 is sleeved in described sleeve pipe 10, and one turning is connected with the fixed block 4, its another turning and institute
Cam 5 is stated to connect, the power transmission shaft 3 is rotatably provided on the permanent-magnet breaker 9, and the power transmission shaft 3 axially with it is described
Rotating bar 1 is axially vertical, and the power transmission shaft 3 links with the magnet steel 91 on permanent-magnet breaker 9, and the connecting lever 7 is fixed on the biography
With the 5 corresponding position of cam on moving axis 3, and the free end of the connecting lever 7 and the outer peripheral edge of the cam 5 offset.Using
Structure in the application example, can in switch cubicle peripheral operation to permanent-magnet breaker quick manual separating brake, when permanent-magnet breaker 9 by
Testing position to operating position it is mobile or from operating position to testing position move when, the drive sleeve pipe 10 of fixed block 4 is along rotating bar 1
Axial movement, therefore the matching relationship between cam and the connecting lever can be kept all the time, therefore the device both can be in testing position
When manual brake separating and can meet the quick manual separating brake at operating position, effectively increase security.
The operation principle of the application example is:Permanent-magnet breaker 9 is in testing position:When permanent-magnet breaker 9 is in combined floodgate shape
During state, the operation handle 2 is locked in closing position by the handle locking mechanism, and the reduction torsion spring 6 is in energy storage state,
When needing emergency opening, handle locking mechanism described in manual operation releases locking to operation handle 2, the operation handle 2 and
The quick rotation under the reset response of the reduction torsion spring 6 of rotating bar 1 resets, and drives described sleeve pipe 10 and cam 5 together to turn
It is dynamic to reset, the cam 5 rotate reset during the high point of cam 5 drive the connecting lever 7 to move up, the connecting lever 7 to
Upper movement simultaneously drives the power transmission shaft 3 to rotate, driven when the power transmission shaft 3 rotates permanent-magnet breaker 9 magnet steel 91 thread off so as to
Make the quick acting switching-off of permanent-magnet breaker 9, reach the purpose of emergency opening, locked operation handle by handle locking mechanism after separating brake
In open position;When closing a floodgate again, first release the handle operation mechanism and operation handle 2 is locked in open position, then
The operation handle 2 is rotated to closing position, the band of operation handle 2 during the operation handle 2 is rotated to closing position
Sleeve pipe 10 and cam 5 in turn lever 1 and rotating bar 1 are rotated, and reduction torsion spring 6 is compressed into energy storage state, at the same time,
The high point of cam 5 leaves connecting lever 7, then operates and permanent-magnet breaker closes a floodgate again.Permanent-magnet breaker is in operating position (permanent magnetism
Breaker moves forward 20cm by testing position and reaches operating position) when, the operating method of emergency opening is same as above.
In the application example, in the rotating bar 1 and described sleeve pipe 10 cross sectional shape of tube chamber be the semicircle that matches or
It polygon, so may insure to drive described sleeve pipe 10 to rotate when the rotating bar 1 rotates, and can realize that described sleeve pipe 10 can
Moved axially in the rotating bar 1 along rotating bar 1.
In the application example, the rotating bar 1 is equipped with buffer spring 18 close to one end outer cover of the front panel 81, uses
This structure, when permanent-magnet breaker 9 is mobile from operating position to testing position and will reach testing position, buffer spring
18 contact with permanent-magnet breaker so as to play cushioning effect.
Further, coordinate the fixed block 4 and described multiple respectively with the cam 5 provided with two in described sleeve pipe 10
Position torsion spring 6 is positioned at positioning element 11 in described sleeve pipe 10, i.e. two positioning elements 11 are engaged pair with cam 5 respectively
Fixed block 4 and reduction torsion spring 6 are positioned, and depart from described sleeve pipe 10 to prevent from covering reduction torsion spring 6 and the fixed block 4, specifically
The positioning element 11 can be the jump ring being installed in described sleeve pipe 10.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model is extended out and still fall within this practicality
New protection domain.
