Embodiment
By reference to the accompanying drawings electric railway isolating switch motor-operating mechanism central control device structure of the present invention is illustrated.
Electric railway isolating switch motor-operating mechanism of the present invention adopts the screw-nut kind of drive to combine with circuit breaker, mechanical drive mode is utilized to replace general contactor, relay control mode, circuit breaker reliably can cut off DC motor power, can effectively evade again because the decay of remote control signal and interference cause the risk of motor-operating mechanism malfunction, tripping.
A kind of electric railway isolating switch motor-operating mechanism central control device of the present invention, this device comprises circuit breaker plate A1, circuit breaker plate B2, separating brake circuit breaker 3, combined floodgate circuit breaker 4, circuit breaker draw-in groove 5, breaker mounting plate 6, stage clip 7, screw 8, direct current machine 9, circuit breaker shift fork 10, connecting rod 11, main transmission 12, fastening bolt 13, spaced stud 14, guide rod 15.
Described circuit breaker plate A1 and circuit breaker plate B2 is fixed in main transmission 12 lower plate by spaced stud 14, moved around by the promotion of the screw 8 spacer conduit along spaced stud 14, described main transmission 12 base plate is fixed with breaker mounting plate 6, while be provided with separating brake circuit breaker 3 on breaker mounting plate 6, combined floodgate circuit breaker 4, while be provided with circuit breaker draw-in groove 5, by fastening bolt 13 by circuit breaker draw-in groove 5 and separating brake circuit breaker 3, combined floodgate circuit breaker 4 is clamped on breaker mounting plate 6, by bolt, circuit breaker shift fork 10 is fixed in draw-in groove at the two ends of circuit breaker draw-in groove 5, under the drive of screw 8, circuit breaker shift fork 10 carries out divide-shut brake action along connecting rod 11 at circuit breaker draw-in groove 5 pairs of circuit breakers, screw 8 is provided with in the conduit of main transmission 12 lower plate, guide rod 15 two ends arrange stage clip 7 respectively and are tightened by bolts, when stage clip 7 and circuit breaker plate A1 or circuit breaker plate B2 contact, guide rod 15 is moved freely by the preformed hole position of screw 8.
