Detailed description of the invention
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
As depicted in figs. 1 and 2, the mechanical locking device for isolation circuit breakers spring structure of the present embodiment, including with
The ground cutter (not shown) divide-shut brake of chopper and make the connecting rod 1 of straight reciprocating motion, for limiting spring mechanism electrical apparatus release 2
Spacer pin 3 and for driving spacer pin 3 to make the drive mechanism 4 of straight reciprocating motion, drive mechanism 4 is located at connecting rod 1 and limit
Between the pin 3 of position, this is used for the mechanical locking device of isolation circuit breakers spring structure, utilizes connecting rod 1, drive mechanism 4 and spacing
The ground cutter of chopper is associated locking by pin 3 with spring mechanism, and simple in construction, when chopper is in open position, if ground cutter closes
Lock then drives spacer pin 3 to insert in the electrical apparatus release 2 of spring mechanism, and chopper cannot enter to make, and after ground cutter separating brake, spacer pin 3 then moves back
Going out electrical apparatus release 2, chopper keeps properly functioning, it is possible to effectively prevent maloperation and reliability high.
Drive mechanism 4 includes travelling gear 41 and the drive link 42 of travelling gear 41 synchronous axial system and is fixedly arranged on connecting rod 1
On trundle 43, drive link 42 offers waist-shaped hole 421, trundle 43 is positioned in waist-shaped hole 421, and spacer pin 3 sets
There is a rack segments 31 engaged with travelling gear 41, drive mechanism 4 stable drive, reliable.In the present embodiment, drive link 42 one end with
Travelling gear 41 is fixing to be connected, and waist-shaped hole 421 is opened in drive link 42 other end, it is achieved between drive link 42 and travelling gear 41
Be synchronized with the movement, between travelling gear 41 with gear shaft 44 use flat key be connected, the most also can be by trundle 43
It is coaxially disposed with gear shaft 44, it is possible to realize being synchronized with the movement between the two.
In the present embodiment, the gear shaft 44 of travelling gear 41 is installed on an axle bed 45, between gear shaft 44 and axle bed 45
It is provided with axle sleeve 46 so that travelling gear 41 goes slick.
