Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of circuit breaker cart turnover car interlock as depicted in figs. 1 and 2, comprise turnover mechanism of car interlocking 9 and spring mechanism interlocking 1, main interlocking 2 is provided with between turnover mechanism of car interlocking 9 and spring mechanism interlocking 1, the top of main interlocking 2 is provided with to be interlocked 9 interlock plates be fixedly connected with 3 by pin 10 and turnover mechanism of car, the left part of main interlocking 2 is provided with back-moving spring 4, the right-hand member of main interlocking 2 is connected with circuit breaker cart frame by bearing pin 21, the left end of main interlocking 2 is flexibly connected with transmission connecting rod mechanism, transmission connecting rod mechanism comprises connecting plate 6, connecting lever 7 and macro-axis connecting lever 8, connecting lever 7 is connected with circuit breaker cart frame with macro-axis connecting lever 8, the two ends of connecting plate 6 respectively with connecting lever 7 and macro-axis connecting lever 8 hinged, connecting plate 6 is provided with at least two spacer pins 5.
A kind of circuit breaker cart turnover car interlock as shown in Figure 3 and Figure 4, better coordinate to make main interlocking 2 and interlock plate 3, main interlocking grooves 11 is provided with above the middle part of main interlocking 2, the bottom of interlock plate 3 is provided with the interlock plate groove 12 suitable with main interlocking grooves 11, better coordinate with spring interlocking device 1 to make main interlocking 2, circuit breaker cart is locked more rapidly and effectively, below the middle part of main interlocking 2, be provided with arc convex 13, arc convex 13 and spring mechanism are interlocked and 1 to be contacted.
The course of work of the present utility model is as follows: as shown in Figure 1, when circuit breaker is in "on" position, if need to carry out the operation of turnover car, drive interlock plate 3 moves downward by turnover mechanism of car interlocking 9, interlock plate 3 and main interlocking 2 are by interlock plate groove 12 and the grafting of main interlocking grooves 11, the left end of main interlocking 2 needs to overcome the pulling force of back-moving spring 4 and moves downward around bearing pin 21, but because circuit breaker is in "on" position, macro-axis connecting lever 8 and connecting plate 6 are due to the effect of spring mechanism, it is made relatively to be in upper, spacer pin 5 on connecting plate 6 limits moving downward of main interlocking 2, thus achieve circuit breaker cannot carry out under "on" position turnover car operation, only under breaker open operation state, spring mechanism drives macro-axis connecting lever 8 to rotate clockwise, connecting plate 6 is made relatively to be in bottom, spacer pin 5 is cancelled the restriction of main interlocking 2, turnover mechanism of car interlocking 9 drives interlock plate 3 to move downward, the left end of main interlocking 2 moves downward around bearing pin 21, back-moving spring 4 stretches, after turnover car has operated, turnover mechanism of car interlocking 9 drives interlock plate 3 to move upward, main interlocking 2 automatically resets under the pulling force effect of back-moving spring 4, for turnover car ready for operation next time.
As shown in Figure 2, when circuit breaker cart is when carrying out the operation of turnover car, turnover mechanism of car interlocking 9 has driven interlock plate 3 to move downward, interlock plate 3 is by interlock plate groove 12 and the grafting of main interlocking grooves 11, the left end of main interlocking 2 is rotated down around bearing pin 21, arc convex 13 on main interlocking 2 makes spring mechanism interlocking 1 move downward, limit the closing operation of circuit breaker after spring mechanism interlocking 1 moves downward, thus achieve circuit breaker cart and carrying out not allowing closing operation in the operating process of turnover car.
