Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 to Figure 3, the earthed switch of turbine and worm mechanism and circuit breaker front axle interlocking device, comprise interlocking pressing plate 1, connecting rod 2, connecting lever 3, pitman shaft 4, interlock plate 6, earthed switch 7, turbine and worm transmission mechanism 8, front propeller shaft 1, hub splines 10, front propeller shaft 2 11, travelling nut 12, interlocking guide rod 13 and guide rail 14, the top of described interlocking pressing plate 1 is provided with connecting rod 2 and connecting lever 3, one end of connecting lever 3 is connected with connecting rod 2, the other end of connecting lever 3 is connected with pitman shaft 4, pitman shaft 4 is provided with interlock plate 6 and spring mechanism 5, one end of interlock plate 6 is arranged on the tapping on guide rail 14, described interlock plate 6 is connected with spring mechanism 5, the other end of spring mechanism 5 connects on-board the circuit breaker, one end of described front propeller shaft 2 11 connects front propeller shaft 1 by hub splines 10, front propeller shaft 1 connects turbine and worm transmission mechanism 8, described turbine and worm transmission mechanism 8 is connected with earthed switch 7, and the other end of described front propeller shaft 2 11 connects interlocking guide rod 13 by travelling nut 12.
The utility model is when reality uses, and when circuit breaker is in test position time, press interlocking pressing plate 1 with hand, while interlocking pressing plate 1 moves down, drivening rod 2 and connecting lever 3 move down; The rotation of drivening rod axle 4 while connecting lever 3 moves down, be arranged on interlock plate 6 on pitman shaft 4 under the effect of spring mechanism 5, rotated inwards by the perforate on guide rail 14, thus blocked the movement of circuit breaker, now can deciliter earthed switch 7, thus achieve the interlocking when shake earthed switch 7 to circuit breaker.Now use earthed switch 7 crank rocking-turn front propeller shaft 2 11, then by hub splines 10 and front propeller shaft 1, turbine and worm transmission mechanism 8 worked thus reach the function of deciliter earthed switch 7.Seesawing of interlocking guide rod 13 is driven by travelling nut 12 while shake front propeller shaft 2 11.Guide rod of now interlocking is pressed on interlocking pressing plate, interlocking pressing plate can not be moved up, thus realize interlocking.Otherwise when circuit breaker is in service position time, due to the effect of spring mechanism 5, can not rotate inwards, interlocking pressing plate can not move down, interlocking guide rod now is also in below interlocking pressing plate, also can ensure that interlocking pressing plate 1 can not move down, the crank of earthed switch 7 can not put in and shake earthed switch 7, thus plays dual fail-safe.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
