Technical Field
[0001] The present invention relates to the technical field of circuit breakers, and particularly to a driving device for a circuit breaker of a locomotive auxiliary machine drive system. Background Art
[0002] The circuit breaker of the locomotive auxiliary machine drive system is an important protection device in the locomotive electrical system. During normal operation, it connects or disconnects the circuit of the auxiliary machine drive system as needed to achieve the start, stop, and operation control of locomotive auxiliary machines such as traction ventilators and air compressors.
[0003] In the prior art, for the sake of use efficiency, electromagnetic drive is adopted for the drive system circuit breaker. Although the electromagnetic drive has relatively high efficiency, its stability and reliability are difficult to ensure in a high-voltage and large-current environment. In addition, the drive system circuit breaker of the prior art also shows deficiencies in terms of control accuracy and intelligent level, and it is difficult to meet the high standards of high precision, high reliability, and intelligent control required by modern locomotive electrical systems. Therefore, the present invention provides a driving device for a circuit breaker of a locomotive auxiliary machine drive system. Summary of the Invention
[0004] The purpose of the present invention is to provide a driving device for a circuit breaker of a locomotive auxiliary machine drive system to solve the problems raised in the above background art.
[0005] The technical solution of the present invention is: A driving device for a circuit breaker of a locomotive auxiliary machine drive system, including a driving box, one side of the driving box is fixedly connected with an input box, and the same side of the driving box and the input box is fixedly connected with a circuit breaker box. A transmission shaft is rotatably connected inside the driving box. Two first rotating rings are fixedly connected to the outer side of the transmission shaft. The same ends of the first rotating rings are respectively rotatably connected with second rotating rings. The ends of the second rotating rings far from the first rotating rings are rotatably connected with third rotating rings. A first push plate is fixedly connected to the outer side of the first rotating ring. A second push plate is fixedly connected to the outer side of the second rotating ring. A third push plate is fixedly connected to the outer side of the third rotating ring. A fixing plate is fixedly connected inside the driving box. One side of the fixing plate is fixedly connected with an installation ring. The transmission shaft is rotatably connected to the installation ring. One side of the installation ring is fixedly connected with an installation inner cylinder. The second rotating ring is rotatably connected to the outer side of the installation inner cylinder, and a first torsion spring is installed between the installation inner cylinder and the second rotating ring. The third rotating ring is rotatably connected to the outer side of the installation inner cylinder, and a second torsion spring is installed between the installation inner cylinder and the third rotating ring. The positions of the two second push plates and the two third push plates are opposite. The two second push plates are respectively located on the opposite sides of the two first push plates. The third push plate is located on the other side of the first push plate. An output gear is fixedly connected to the outer side of the third rotating ring. An excess slider is slidably clamped inside the driving box. A bottom limit slider is slidably clamped inside the driving box. One side of the excess slider and the bottom limit slider are respectively fixedly connected with an output tooth row. The two output tooth rows are respectively meshed with the two output gears. When in use: The rotation of the transmission shaft is controlled by different currents or voltages. When within the threshold, it rotates within the arc-shaped space formed by the first push plate, the second push plate, and the third push plate. When exceeding the threshold, because the positions of the two second push plates and the two third push plates are opposite, one first push plate will push the second push plate, and the other first push plate will cross over the third push plate, causing one first push plate to push the second push plate to rotate, driving the third push plate to rotate, driving the output gear to rotate, driving the output tooth row to move, for controlling the circuit breaker and sending a signal exceeding the threshold. Similarly, when below the threshold, it will reverse. The other first push plate will push the adjacent second push plate, and then push the third push plate, driving the output gear to rotate, driving the output tooth row to move in the opposite direction, for controlling the circuit breaker and sending a signal below the threshold. Through the settings of the first torsion spring and the second torsion spring, it is convenient to reset.
[0006] Preferably, two connection rows are fixedly connected inside the circuit breaker box. Two buffer conductive plates are fixedly connected between the two connection rows. An incoming wire connection board and an outgoing wire connection board are respectively fixedly connected to opposite sides of the two connection rows. Conductive rows are fixedly connected to opposite sides of the two buffer conductive plates. Guide rows are fixedly connected to both ends of the conductive row. An excess guide piece and a bottom guide piece are slidably clamped between the conductive row and the connection row. The excess guide piece is fixedly connected to an excess slider, and the bottom guide piece is fixedly connected to a bottom excess slider. A control plug row is slidably clamped between the two buffer conductive plates. The control plug row is slidably clamped inside the circuit breaker box. The top of the control plug row is made of insulating material. One end of the transmission shaft penetrates the input box, and an input gear is rotatably connected to the end of the transmission shaft. An induction sensor is slidably clamped on the top of the input box. A moving tooth column is fixedly connected to the bottom end of the induction sensor. The moving tooth column meshes with the input gear. During use: The incoming wire and the outgoing wire are connected and installed through the incoming wire connection board and the outgoing wire connection board. The movement of the moving tooth column is controlled through the induction sensor, the rotation of the transmission shaft is controlled, the excess guide piece and the bottom guide piece are driven to move, and the device is conducted. At the same time, the movement of the control plug row can also be manually controlled to conduct the device. By setting the buffer conductive plates and the guide rows, the internal wear of the drive box is avoided, so that the excess guide piece and the bottom guide piece cannot be accurately inserted.
[0007] The present invention provides a driving device for a circuit breaker of a locomotive auxiliary machine drive system through improvement. Compared with the prior art, it has the following improvements and advantages: First: For the driving device of the circuit breaker of the locomotive auxiliary machine drive system of the present invention, the rotation of the transmission shaft is controlled by different currents or voltages. When within the threshold, it rotates within the arc-shaped space formed by the first push plate, the second push plate, and the third push plate. When exceeding the threshold, because the positions of the two second push plates and the two third push plates are opposite, one first push plate will push the second push plate, and the other first push plate will cross over the third push plate, causing one first push plate to push the second push plate to rotate, driving the third push plate to rotate, driving the output gear to rotate, driving the output tooth row to move, and controlling the circuit break, and sending a signal exceeding the threshold. Similarly, when below the threshold, it will reverse, and the other first push plate will push the adjacent second push plate, and then push the third push plate, driving the output gear to rotate, driving the output tooth row to move in the opposite direction, controlling the circuit break, and sending a signal below the threshold. Through the setting of the first torsion spring and the second torsion spring, it is convenient to reset. Second: For the driving device of the circuit breaker of the auxiliary machine drive system of a locomotive described in the present invention, the incoming line and the outgoing line are connected and installed through the incoming line connection board and the outgoing line connection board. The movement of the movable tooth column is controlled by the induction sensor, the rotation of the transmission shaft is controlled, the excess guide piece and the bottom leading piece are driven to move, so as to control the conduction of the control device. At the same time, the movement of the socket can also be controlled manually to make the device conduct. By setting the buffer conductive plate and the guide row, the internal wear of the drive box is avoided, so that the excess guide piece and the bottom leading piece cannot be accurately inserted; Summary: The driving device of the circuit breaker of the auxiliary machine drive system of a locomotive described in the present invention not only solves the problem that the stability and reliability of the electromagnetic drive in the high-voltage and large-current environment are difficult to ensure in the prior art, but also improves the control accuracy and the intelligent level, meeting the high standards of high precision, high reliability and intelligent control required by the modern locomotive electrical system.

[0010] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0011] The present invention provides a driving device for a circuit breaker of a locomotive auxiliary machine drive system through improvement. The technical solution of the present invention is as follows: As Figures 1 - 7As shown in the figure, a driving device for a circuit breaker of a locomotive auxiliary machine drive system includes a driving box 1. One side of the driving box 1 is fixedly connected with an input box 3. The same side of the driving box 1 and the input box 3 is fixedly connected with a circuit breaker box 2. A transmission shaft 14 is rotatably connected inside the driving box 1. Two first rotating rings 18 are fixedly connected to the outer side of the transmission shaft 14. The same ends of the first rotating rings 18 are respectively rotatably connected with second rotating rings 20. The ends of the second rotating rings 20 far from the first rotating rings 18 are rotatably connected with third rotating rings 22. A first push plate 19 is fixedly connected to the outer side of the first rotating ring 18. A second push plate 21 is fixedly connected to the outer side of the second rotating ring 20. A third push plate 23 is fixedly connected to the outer side of the third rotating ring 22. A fixing plate 15 is fixedly connected inside the driving box 1. One side of the fixing plate 15 is fixedly connected with a mounting ring 16. The transmission shaft 14 is rotatably connected with the mounting ring 16. One side of the mounting ring 16 is fixedly connected with a mounting inner cylinder 17. The second rotating ring 20 is rotatably connected to the outer side of the mounting inner cylinder 17.

The third rotating ring 22 is rotatably connected to the outer side of the mounting inner cylinder 17. A second torsion spring 26 is installed between the mounting inner cylinder 17 and the third rotating ring 22. The positions of the two second push plates 21 and the two third push plates 23 are opposite. The two second push plates 21 are respectively located on the opposite sides of the two first push plates 19. The third push plate 23 is located on the other side of the first push plate 19. An output gear 24 is fixedly connected to the outer side of the third rotating ring 22. An excess slider 28 is slidably clamped inside the driving box 1. A bottom limit slider 29 is slidably clamped inside the driving box 1. One side of the excess slider 28 and the bottom limit slider 29 are respectively fixedly connected with an output tooth row 27. The two output tooth rows 27 are respectively meshed with the two output gears 24. When in use: The rotation of the transmission shaft 14 is controlled by different currents or voltages. When within the threshold, the first push plate 19 rotates within the arc-shaped space formed by the second push plate 21 and the third push plate 23. When exceeding the threshold, because the positions of the two second push plates 21 and the two third push plates 23 are opposite, one first push plate 19 will push the second push plate 21, and the other first push plate 19 will cross over the third push plate 23, causing one first push plate 19 to push the second push plate 21 to rotate, driving the third push plate 23 to rotate, driving the output gear 24 to rotate, driving the output tooth row 27 to move, for controlling the circuit breaker and sending a signal exceeding the threshold. Similarly, when below the threshold, it will reverse. The other first push plate 19 will push the adjacent second push plate 21, and then push the third push plate 23, driving the output gear 24 to rotate, driving the output tooth row 27 to move in the opposite direction, for controlling the circuit breaker and sending a signal below the threshold. Through the settings of the first torsion spring 25 and the second torsion spring 26, it is convenient to reset.
[0012] Furthermore, two connection rows 6 are fixedly connected inside the circuit breaker box 2. Two buffer conductive plates 7 are fixedly connected between the two connection rows 6. An incoming wire connection board 4 and an outgoing wire connection board 5 are respectively fixedly connected to the opposite sides of the two connection rows 6. Conductive rows 8 are fixedly connected to the opposite sides of the two buffer conductive plates 7. Guide rows 9 are fixedly connected to both ends of the conductive row 8. An excess conductive piece 30 and a bottom leading piece 31 are slidably clamped between the conductive row 8 and the connection row 6. The excess conductive piece 30 is fixedly connected to an excess slider 28, and the bottom leading piece 31 is fixedly connected to a bottom excess slider 29. A control socket row 10 is slidably clamped between the two buffer conductive plates 7. The control socket row 10 is slidably clamped inside the circuit breaker box 2. The top of the control socket row 10 is made of insulating material. One end of a transmission shaft 14 penetrates through the input box 3, and an input gear 13 is rotatably connected to the end of the transmission shaft 14. An induction sensor 11 is slidably clamped on the top of the input box 3. A moving tooth column 12 is fixedly connected to the bottom end of the induction sensor 11. The moving tooth column 12 meshes with the input gear 13. When in use: The incoming wire and the outgoing wire are connected and installed through the incoming wire connection board 4 and the outgoing wire connection board 5. The movement of the moving tooth column 12 is controlled through the induction sensor 11, the rotation of the transmission shaft 14 is controlled, the excess conductive piece 30 and the bottom leading piece 31 are driven to move, so as to conduct the control device. At the same time, the movement of the control socket row 10 can also be manually operated to conduct the device. By providing the buffer conductive plates 7 and the guide rows 9, wear inside the drive box 1 is avoided, so that the excess conductive piece 30 and the bottom leading piece 31 cannot be accurately inserted.
[0013] Working principle: When in use: The rotation of the transmission shaft 14 is controlled by different currents or voltages. When within the threshold, the first push plate 19 rotates within the arc-shaped space formed by the second push plate 21 and the third push plate 23. When exceeding the threshold, because the positions of the two second push plates 21 and the two third push plates 23 are opposite, one first push plate 19 will push the second push plate 21, and the other first push plate 19 will cross over the third push plate 23, causing one first push plate 19 to push the second push plate 21 to rotate, driving the third push plate 23 to rotate, driving the output gear 24 to rotate, driving the output tooth row 27 to move, for controlling the circuit break and sending a signal exceeding the threshold. Similarly, when below the threshold, it will reverse. The other first push plate 19 will push the adjacent second push plate 21, and then push the third push plate 23, driving the output gear 24 to rotate, driving the output tooth row 27 to move in the opposite direction, for controlling the circuit break and sending a signal below the threshold. Through the settings of the first torsion spring 25 and the second torsion spring 26, it is convenient to reset. The incoming line and the outgoing line are connected and installed through the incoming line connection board 4 and the outgoing line connection board 5. The movement of the moving tooth column 12 is controlled by the import sensor 11, controlling the rotation of the transmission shaft 14, driving the excess guide piece 30 and the bottom guide piece 31 to move, for controlling the conduction of the device. At the same time, the movement of the socket 10 can also be controlled manually to conduct the device. By setting the buffer conductive plate 7 and the guide row 9, wear inside the drive box 1 is avoided, preventing the excess guide piece 30 and the bottom guide piece 31 from being accurately inserted.
