This significantly improves the safety of operators during plugging / unplugging operations or contact with sockets, effectively preventing electric shock accidents and enhancing electrical safety.

[0038] Furthermore, by setting up a third contactor coil and its normally closed contacts, a two-way interlock between the locomotive power supply module and the backup power supply is achieved, so that only one of the locomotive power supply module or the backup power supply can be supplied at the same time, which has a high power supply reliability.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] This invention provides an automatic molten iron ladle covering system for locomotives. Figure 1 This is a schematic diagram of an automatic molten iron ladle covering system for a locomotive, provided as an embodiment of the present invention. (Reference) Figure 1The automatic ladle covering system for locomotives includes: a locomotive power supply module 1, a power supply control module 2, a connector 3, and an automatic ladle covering module 4. The locomotive power supply module 1 includes a first power output terminal 11, a second power output terminal 12, a ground terminal 13, and a power neutral point 14; the first power output terminal 11 outputs a first power supply, and the second power output terminal 12 outputs a control power supply. The first input terminal 201 of the power supply control module 2 is connected to the first power output terminal 11 and the power neutral point 14, the second input terminal 202 is connected to the second power output terminal 12, and the first output terminal 211 is connected to the ground terminal. The power supply control module 2 receives the first power supply and the control power supply; it also transmits the first power supply through its second output terminal 212 when the system is on, and performs a self-locking operation while energized. The first input terminal 301 of connector 3 is plugged into the third output terminal 213 of power supply control module 2, the first output terminal 311 of connector 3 is plugged into the third input terminal 203 of power supply control module 2, and the second input terminal 302 of connector 3 is plugged into the second output terminal 212 of power supply control module 2. Connector 3 includes a short-circuit structure. The short-circuit structure is used to short-circuit the third input terminal 203 and the third output terminal 213 of power supply control module 2. When the third input terminal and the third output terminal of power supply control module 2 are short-circuited, the power supply circuit between the control power supply and power supply control module 2 is connected, and power supply control module 2 is energized. Connector 3 is also used to transmit the first power supply. The automatic ladle cover module 4 is connected to connector 3 and is used to control the opening or closing of the ladle insulation cover in the locomotive when energized.

[0048] The locomotive power supply module 1 can output a first power supply through the first power output terminal 11, which can be, for example, 380V AC power. The second power output terminal 12 is used to output control power, which can be, for example, 110V DC power. The power supply control module 2 can operate when the control power is connected, and transmits the first power supply to the ladle automatic capping module 4 through the connector 3, so that the ladle automatic capping module 4 controls the ladle insulation cover in the locomotive to close, thereby realizing the automatic capping and insulation of the molten iron ladle transported by the locomotive. When the ladle insulation cover in the locomotive is in the closed state, the ladle automatic capping module 4 can also control the ladle insulation cover in the locomotive to open automatically.

[0049] However, since the power supply control module 2 does not have a connection path between the first power output terminal 11 and the ground terminal 13 after it is connected to the locomotive power supply module 1, it is necessary to connect the power supply control module 2 to the connector 3. The control power received by the second input terminal 202 of the power supply control module 2 can be connected to the ground terminal through the third output terminal 213 of the power supply control module 2, the first input terminal 301 of the connector 3, the short-circuit structure of the connector 3, the first output terminal 311 of the connector 3, the third input terminal 203 of the power supply control module 2, and the first output terminal 211 of the power supply control module 2 to form a loop. Therefore, when the connector 3 is not connected to the power supply control module 2, the power supply control module 2 cannot form a power supply loop for the control power, and the power supply control module 2 cannot be energized. This also prevents the power supply control module 2 from transmitting the first power supply to the connector 3. At this time, the automatic molten iron ladle cover module 4 cannot be energized.

[0050] Therefore, it can be seen that the complete path of the control power supply of the input power supply control module 2 depends on the connector 3. That is, if the control power supply is to form a complete circuit in the power supply control module 2, it is necessary to short-circuit the third output terminal 213 and the third input terminal 203 of the power supply control module 2 through the short-circuit structure of the connector 3.

[0051] After each end of connector 3 is connected to each end of power supply control module 2, power supply control module 2 can operate according to the control power supply. Power supply control module 2 can connect its first input terminal 201 and second output terminal 212, so that the first power supply received by the first input terminal 201 can be transmitted to connector 3 through the second output terminal 212, and input to the molten iron ladle automatic capping module 4 through connector 3, so that the molten iron ladle automatic capping module 4 can operate. At the same time, power supply control module 2 is energized and self-locking, so that its first input terminal 201 and second output terminal 212 remain connected.

[0052] The technical solution provided by this invention, by setting up a locomotive power supply module, realizes the output of a first power supply and a control power supply. After the power supply control module is plugged into the connector, upon receiving the control power, it transmits the first power supply to the automatic ladle cover module via the connector, energizing the automatic ladle cover module and enabling automatic opening or closing of the ladle insulation cover in the locomotive, resulting in high working efficiency. During the transmission of the first power supply, the power supply control module is energized and self-locking, ensuring high power supply reliability. Furthermore, by connecting the connector to the power supply control module, it is ensured that when the connector is not connected to the power supply control module and the automatic ladle cover module, the first power supply output from the locomotive power supply module will not be available on the power supply control module. This greatly improves the safety of operators during plugging / unplugging operations or contact with sockets, effectively preventing electric shock accidents and improving electrical safety.

[0053] Figure 2 This is a schematic diagram of another automatic molten iron ladle covering system for locomotives provided in an embodiment of the present invention. (Reference) Figure 2 Based on the above embodiments, optionally, the power supply control module 2 includes: a first power supply control unit 21 and a second power supply control unit 22. The input terminal of the first power supply control unit 21 is connected to the first power output terminal 11 and the power neutral point 14. The first power supply control unit 21 is used to transmit the first power supply when it is turned on. The first input terminal of the second power supply control unit 22 is connected to the second power output terminal 12, and the first output terminal of the second power supply control unit 22 is connected to the ground terminal 13. The second power supply control unit 22 is used to control the turning on or off of the first power supply control unit 21, and is energized and self-locking when the first power supply control unit 21 is turned on. A connector 3 is plugged into and connected to the output terminal of the first power supply control unit 21, the second output terminal of the second power supply control unit 22, and the second input terminal of the second power supply control unit 22. The connector 3 is used to connect the first power supply control unit 21 to the automatic ladle capping module 4; the connector 3 is also used to connect the second output terminal of the second power supply control unit 22 and the second input terminal of the second power supply control unit 22.

[0054] When connector 3 is plugged into the second power supply control unit 22, the second power supply control unit 22 connects the circuit between itself, the second power output terminal 12 and the ground terminal 13 through connector 3. The second power supply control unit 22 is powered on and can be used to control the first power supply control unit 21 to turn on or off. When the first power supply control unit 21 is turned on, it is energized and self-locked to keep the first power supply control unit 21 in the on state.

[0055] The first power supply control unit 21 is connected between the locomotive power supply module 1 and the connector 3. After the first power supply control unit 21 is plugged into the connector 3, it can transmit the first power supply output by the locomotive power supply module 1 to the connector 3, so that the molten iron ladle automatic cover module 4 can be energized and operated.

[0056] Continue to refer to Figure 2 Based on the above embodiments, optionally, the shorting structure 31 includes: a first plug C1 and a second plug C2. The first plug C1 is inserted into the first socket D1 of the third input terminal of the power supply control module 2, and the second plug C2 is inserted into the second socket D2 of the third output terminal of the power supply control module 2. The first plug C1 and the second plug C2 are shorted internally within the shorting structure 31. The connector 3 further includes: a second connecting unit 31; the second connecting unit 31 includes: a third plug C3, a fourth plug C4, a fifth plug C5, and a sixth plug C6. The second output terminal of the power supply control module 2 includes: a third socket D3, a fourth socket D4, a fifth socket D5, and a sixth socket D6. The third plug C3, the fourth plug C4, the fifth plug C5, and the sixth plug C6 are inserted into the third socket D3, the fourth socket D4, the fifth socket D5, and the sixth socket D6 in a one-to-one correspondence. The second connection unit 32 also includes: a seventh socket D7, an eighth socket D8, a ninth socket D9, and a tenth socket D10. The molten iron ladle automatic cover module 4 includes: a seventh plug C7, an eighth plug C8, a ninth plug C9, and a tenth plug C10. The seventh socket D7, the eighth socket D8, the ninth socket D9, and the tenth socket D10 are connected to the seventh plug C7, the eighth plug C8, the ninth plug C9, and the tenth plug C10 in a one-to-one correspondence.

[0057] Inside the shorting structure 31, the first plug C1 and the second plug C2 are shorted. When the first plug C1 and the second plug C2 are respectively inserted into the first socket D1 and the second socket D2, it is equivalent to shorting the first socket D1 and the second socket D2 through the shorting structure 31, allowing the second power supply control unit 22 in the power supply control module 2 to form a circuit between the second power output terminal 12 and the ground terminal 13. When the first plug C1 and the second plug C2 are not respectively inserted into the first socket D1 and the second socket D2, the second power supply control unit 22 cannot form a live circuit and therefore cannot control the first power supply control unit 21, keeping the first power supply control unit 21 in the power supply control module 2 in an open state. This makes the connector 3 non-energized, reducing the risk of electric shock when contacting the connector 3.

[0058] The automatic ladle capping module 4 can also be connected to the connector 3 via a plug-in connection. This configuration improves the convenience of connecting the automatic ladle capping module 4 to the connector 3.

[0059] Figure 3This is a schematic diagram of another automatic molten iron ladle covering system for locomotives provided in an embodiment of the present invention. (Reference) Figure 3 Based on the above embodiments, optionally, the second power supply control unit 22 includes: a self-reset selection switch SB, a first contactor coil KM, and a normally open auxiliary contact KM1.4 of the first contactor coil. The first and second input terminals of the self-reset selection switch SB are both connected to the second power output terminal 12. The first terminal of the first contactor coil KM1 is connected to the second output terminal of the self-reset selection switch SB, and the second terminal of the first contactor coil KM1 is connected to the first input terminal of the connector 3. The first terminal of the normally open auxiliary contact KM1.4 of the first contactor coil is connected to the second input terminal of the self-reset selection switch SB, and the second terminal of the normally open auxiliary contact KM1.4 is used to form a energized self-locking circuit for the first contactor coil KM when it is turned on.

[0060] Specifically, by operating the self-reset selector switch SB to the power-on position, the control power output from the second power output terminal 12 can be transmitted to the first contactor coil KM1 through the self-reset selector switch SB, energizing the first contactor coil KM1. Simultaneously, the normally open auxiliary contact KM1.4 of the first contactor coil closes. Even after the self-reset selector switch SB resets and disconnects from the first contactor coil KM1, the control power can still be transmitted to the first contactor coil KM1 through the normally open auxiliary contact KM1.4, thus forming a energized self-locking circuit for the first contactor coil KM1.

[0061] This invention improves the reliability of power supply to the first contactor coil by setting up a live self-locking circuit for the first contactor coil.

[0062] Continue to refer to Figure 3 Based on the above embodiments, optionally, the first power supply control unit includes: a first normally open contact KM1.1 of the first contactor coil, a second normally open contact KM1.2 of the first contactor coil, and a third normally open contact KM1.3 of the first contactor coil. The first ends of the first normally open contact KM1.1, the second normally open contact KM1.2, and the third normally open contact KM1.3 of the first contactor coil are all connected to the first power output terminal 11, and the second ends of the first normally open contact KM1.1, the second normally open contact KM1.2, and the third normally open contact KM1.3 of the first contactor coil are all connected to the power interface of the connector 3, which is also connected to the power neutral point.

[0063] When the first contactor coil KM1 is energized, the first normally open contact KM1.1, the second normally open contact KM1.2, and the third normally open contact KM1.3 of the first contactor coil are all closed. The first power supply output from the first power output terminal 11 of the locomotive power supply module 1 can be transmitted to the connector 3 through the first normally open contact KM1.1, the second normally open contact KM1.2, and the third normally open contact KM1.3 of the first contactor coil, and then to the ladle automatic capping module 4, so that the ladle automatic capping module 4 is energized and operates.

[0064] Continue to refer to Figure 3 Based on the above embodiments, optionally, the second power supply control unit 2 further includes: a second contactor coil KM2 and a normally closed contact KM2.1 of the second contactor coil. The first end of the second contactor coil KM2 is connected to the first output terminal of the self-resetting selector switch SB, and the second end of the second contactor coil KM2 is connected to the first output terminal of the connector 3. The connector 3 is used to short-circuit the second end of the first contactor coil KM1 and the second end of the second contactor coil KM2. The first end of the normally closed contact KM2.1 of the second contactor coil is connected to the second input terminal of the self-resetting selector switch SB, and the second end of the normally closed contact KM2.1 of the second contactor coil is connected to the first end of the normally open auxiliary contact KM1.4 of the first contactor coil; the normally closed contact KM2.1 of the second contactor coil is used to disconnect the energized self-locking circuit of the first contactor coil KM1 when the second contactor coil KM2 is energized.

[0065] Specifically, by operating the self-reset selector switch SB to the de-energized position, the control power output from the second power output terminal 12 can be transmitted to the second contactor coil KM2 through the self-reset selector switch SB, energizing the second contactor coil KM2. Simultaneously, the normally closed contact KM2.1 of the second contactor coil opens. At this time, the normally closed contact KM2.1 of the second contactor coil disconnects the energized self-locking circuit of the first contactor coil KM1, de-energizing the first contactor coil KM1.

[0066] Figure 4 This is a schematic diagram of another automatic molten iron ladle covering system provided in an embodiment of the present invention. Optionally, based on the above embodiments, the automatic molten iron ladle covering system further includes: a backup power supply 5, connected to the automatic molten iron ladle covering module 4, the backup power supply 5 being used to output a second power supply to the automatic molten iron ladle covering module 4.

[0067] The backup power supply 5 can be a ground power source outside the locomotive, which can replace the first power supply output by the locomotive power supply module 1. For example, the second power supply can have the same voltage level as the first power supply, both being 380V AC.

[0068] Continue to refer to Figure 4 Based on the above embodiments, optionally, the first power supply control unit 21 further includes: a third contactor coil KM3, connected between the second end of the third normally open contact KM1.3 of the first contactor coil and the power supply neutral point 14.

[0069] Optionally, the second power supply control unit 22 further includes: a normally open contact KM3.1 of the third contactor coil, a power-on indicator light LT, and a normally closed contact KM3.2 of the third contactor coil. The first end of the normally open contact KM3.1 of the third contactor coil is connected to the second power output terminal 12, and the second end of the normally open contact KM3.1 of the third contactor coil is connected to the first end of the power-on indicator light LT, which is connected to the ground terminal 13. The power-on indicator light LT illuminates when the normally open contact KM3.1 of the third contactor coil is closed. The first end of the normally closed contact KM3.2 of the third contactor coil is connected to the second output terminal of the self-resetting selector switch SB, and the second end of the normally closed contact KM3.2 of the third contactor coil is connected to the first end of the first contactor coil KM1. The normally closed contact KM3.2 of the third contactor coil is disconnected when the third contactor coil KM3 is energized.

[0070] When the automatic ladle cover module 4 is energized, the third contactor coil KM3 is also energized. The normally open contact KM3.1 of the third contactor coil closes, and the power-on indicator light LT is energized and illuminates, thereby indicating the power-on status of the automatic ladle cover module 4.

[0071] For example, when the automatic ladle capping module 4 is powered by the second power supply, the third contactor coil KM3 is energized, and its normally closed contact KM3.2 is open. If the self-reset selector switch SB is switched to the power supply position, the control power output from the second power output terminal 12 will be unable to be transmitted to the first contactor coil KM1 due to the open normally closed contact KM3.2 of the third contactor coil. Consequently, the first normally open contact KM1.1, the second normally open contact KM1.2, and the third normally open contact KM1.3 of the first contactor coil cannot be closed. At this time, the first power supply cannot be transmitted to the automatic ladle capping module 4, thus achieving interlocking between the locomotive power supply module 1 and the backup power supply 5.

[0072] When the automatic ladle capping module 4 is powered by the first power supply, the third contactor coil KM3 is also energized. At this time, all normally closed contacts of the third contactor coil are open. For example, the backup power supply 5 can also be equipped with normally closed contacts of the third contactor coil, which can be used to control the on / off state of the backup power supply 5. Therefore, when the automatic ladle capping module 4 is powered by the first power supply, the backup power supply 5 cannot output a second power supply to the automatic ladle capping module 4. Through this configuration, bidirectional interlocking between the locomotive power supply module 1 and the backup power supply 5 is achieved, further improving power supply reliability.

[0073] This invention, through the configuration of a third contactor coil, its normally open contact, and a power-on indicator light, achieves a display of the energized status of the automatic ladle covering module. This clearly indicates to on-site personnel that the automatic ladle covering module is currently energized and requires safety attention. Furthermore, by setting the normally closed contact KM3.2 of the third contactor coil, it effectively prevents the simultaneous connection of the first and second AC power supplies (which may have a phase difference) to the automatic ladle covering module, thus preventing potential short circuits and overcurrent risks and maintaining the reliable operation of the locomotive's automatic ladle covering system.

[0074] Optionally, the automatic molten iron ladle covering system can also be equipped with a detection module connected to both ends of the normally open and normally closed contacts of each contactor coil. This module is used to detect the opening and closing status of each normally open and normally closed contact, as well as the voltage and current transmitted through them. When the opening and closing status of a normally open or normally closed contact is abnormal, or when the voltage or current is abnormal, an abnormal signal can be issued to alert relevant personnel.

[0075] This invention also provides a locomotive. This locomotive includes the automatic molten iron ladle covering system provided in any embodiment of this invention, and has similar beneficial effects to the automatic molten iron ladle covering system, which will not be described in detail here.
