Description

Technical Field

[0001] The present invention relates to the field of centralized power EMUs, and in particular to an automatic coupler control device and method for centralized power EMUs. Background Art

[0002] The centralized power EMU uses automatic couplers for automatic coupling between train groups, realizing mechanical connection, electrical connection, and air circuit connection between trains. The automatic coupler is divided into two parts: the electrical coupler and the mechanical coupler. The electrical coupler push mechanism is installed on the upper part of the mechanical coupler, and a cylinder pushes the rod structure to extend and retract the electrical coupler. When the train needs to be coupled, after the mechanical coupler is coupled, it is necessary to charge the rear end of the push cylinder of the push mechanism to extend the electrical coupler. During this process, the electrical coupler rain cover automatically opens; when the train needs to be uncoupled, it is necessary to charge the front end of the push cylinder of the push mechanism to retract the electrical coupler. During this process, the electrical coupler rain cover automatically closes. When the mechanical coupler is uncoupled from the train, it is necessary to charge the mechanical coupler uncoupling cylinder to push the mechanical coupler to uncouple.

[0003] In view of the demand for compressed air for automatic coupler coupling and uncoupling, the centralized power EMU needs to be equipped with an automatic coupler control device and a circuit-controlled solenoid valve is designed to control the on-and-off of the air circuit and control the coupling and uncoupling of the automatic coupler.

[0004] At present, the coupler control device of the centralized power EMU adopts a microcomputer-driven solenoid valve to control the on-off of the air circuit and realize the coupling and uncoupling actions of the electrical coupler and mechanical coupler parts of the automatic coupler.

[0005] When the automatic coupler is connected, after the mechanical coupler is connected, the microcomputer controls the electric coupler connection solenoid valve to be energized through the output signal device, and the compressed air reaches the rear end of the push cylinder of the push mechanism through the solenoid valve, so that the electric coupler is extended to complete the connection. After the connection is completed, the solenoid valve loses power and the air circuit is disconnected. When the automatic coupler is uncoupled, the microcomputer controls the electric coupler uncoupling solenoid valve to be energized through the output signal device, and the compressed air reaches the front end of the push cylinder of the push mechanism through the solenoid valve, so that the electric coupler is retracted. At the same time, the microcomputer controls the mechanical coupler uncoupling solenoid valve to be energized through the output signal device, and the compressed air reaches the mechanical coupler uncoupling cylinder through the solenoid valve to charge the mechanical coupler, and the mechanical coupler is uncoupled. The mechanical coupler uncoupling cylinder is provided with an exhaust port, and the compressed air in the cylinder is slowly discharged through the exhaust port, so that the automatic coupler can be connected again.

[0006] However, the power gain and loss of the solenoid valve is controlled by a single point of the microcomputer output signal device. In some cases, the microcomputer output signal is accidentally triggered, which will cause the mechanical coupler to be accidentally disconnected and the train to be disconnected; the connection and disconnection of the electric coupler adopts two two-position three-way solenoid valves for air circuit control. After the connection of the electric coupler is completed, the solenoid valve loses power and the air circuit is disconnected. During the operation of the train, the electric coupler loses the thrust provided by the compressed air and only relies on its own locking mechanism to maintain the connection state. It is easy to be accidentally disconnected by external forces during operation. After the mechanical coupler is connected, the mechanical coupler disconnection solenoid valves at both ends communicate through the mechanical coupler disconnection cylinder. The mechanical coupler disconnection solenoid valve has an exhaust port. When the diameter of the mechanical coupler disconnection solenoid valve is too small or the compressed air pressure of the EMU is low, when the mechanical coupler disconnection solenoid valve at one end is filled with air, the compressed air will be discharged through the exhaust port of the mechanical coupler disconnection solenoid valve at the other end, resulting in insufficient compressed air pressure in the mechanical coupler disconnection cylinder, which is prone to mechanical coupler disconnection failure. The operation of the electric coupler solenoid valve depends on the circuit. When the EMU is powered off, the electric coupler cannot work. The automatic coupler control device is not an independent module integrated installation. Because of the inconvenience of installation, it needs to be installed as a standard when the power car leaves the factory. The automatic coupler of the power car is an optional component. When the automatic coupler is not installed, the installed automatic coupler control device causes cost waste. The exhaust diameter of the solenoid valve of the automatic coupler control device is large, and the noise is more obvious when exhausting. Summary of the invention

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0025] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0026] The present invention proposes a method for controlling the automatic coupler of a power-concentrated EMU. Figure 1 , including: microcomputer output signal device 1, plate-type pulse two-position five-way solenoid valve 2, mechanical coupler uncoupling solenoid valve 3 and shrink plug 6, The output end of the microcomputer output signal device 1 is connected to the circuit input end of the plate-type pulse two-position five-way solenoid valve 2 and the mechanical coupler disconnecting solenoid valve 3 respectively; The gas circuit output end of the plate-type pulse two-position five-way solenoid valve 2 is connected to the electric coupler, and the gas circuit output end of the mechanical coupler disconnecting solenoid valve 3 is connected to the mechanical coupler; A shrink plug 6 is provided on the exhaust port of the mechanical coupler uncoupling solenoid valve 3 .

[0027] The present invention connects the contact controlled by the microcomputer output signal device 1 in series on the negative line of the solenoid valve in the automatic coupler control circuit, which can avoid the accidental uncoupling of the train caused by the single-point failure of the microcomputer output signal device 1 and the false triggering of the instruction. The plate-type pulse two-position five-way solenoid valve 2 is used to control the air circuit of the electric coupler. The solenoid valve maintains the on-off state of the air circuit after power is supplied, so that the compressed air is continuously supplied after the electric coupler is connected and connected, thereby improving the safety of operation; the plate-type pulse two-position five-way solenoid valve 2 has a manual operation function, and its air circuit can be changed by operating a button or other tool, so that the connection and disconnection of the electric coupler can also be realized when the EMU is powered off; a shrink plug is set on the exhaust port of the mechanical coupler uncoupling solenoid valve 3, so that it is easier to build up compressed air pressure in the uncoupling cylinder when the mechanical coupler is uncoupled, ensuring the reliable uncoupling of the mechanical coupler. The automatic coupler control device is modularly designed, and the air circuit and circuit interfaces are reserved to achieve quick installation. In view of the optional characteristics of the automatic coupler, the modular design can be reserved and installed synchronously with the automatic coupler to save costs.

[0028] In some embodiments, see Figure 1 , and also includes a mechanical coupler gas circuit cut-off plug door 4 and an electrical coupler gas circuit cut-off plug door 5; The mechanical coupler gas circuit shutoff valve 4 is connected to the gas circuit where the mechanical coupler disconnecting solenoid valve 3 is located; The electric coupler gas circuit shutoff valve 5 is connected to the gas circuit where the plate-type pulse two-position five-way solenoid valve 2 is located.

[0029] At the same time, the gas circuit is provided with a mechanical coupler gas circuit cut-off valve 4 and an electrical coupler gas circuit cut-off valve 5, which can isolate the corresponding gas circuit when necessary.

[0030] By isolating the corresponding air circuits through the mechanical coupler air circuit shutoff valve 4 and the electrical coupler air circuit shutoff valve 5, it is possible to prevent the accidental activation of the coupler air circuit due to misoperation or system failure during the train connection or separation process, thereby avoiding possible collisions or derailment accidents. When the air circuit of a part of the train fails, isolating it through the mechanical coupler air circuit shutoff valve 4 and the electrical coupler air circuit shutoff valve 5 can prevent the fault from spreading to the entire braking system and reduce the risk of the train stopping due to a fault. The setting of the mechanical coupler air circuit shutoff valve 4 and the electrical coupler air circuit shutoff valve 5 keeps the coupler air circuit independent of the air circuits of other parts of the train and does not affect each other. This helps to maintain the stability and reliability of the train braking system.

[0031] In some embodiments, see Figure 1 The gas circuit output end of the plate-type pulse two-position five-way solenoid valve 2 is connected to one end of the electric coupler connection gas circuit and the electric coupler disconnection gas circuit; The other end of the electric coupler air circuit is connected to the rear end of the push cylinder of the push mechanism; The other end of the electric coupler uncoupling air circuit is connected to the front end of the pushing cylinder of the pushing mechanism; The pushing cylinder of the pushing mechanism is connected to the electric coupler.

[0032] A plate-type pulse two-position five-way solenoid valve 2nd generation original electric coupler connection solenoid valve and electric coupler disconnection solenoid valve is selected to achieve the corresponding gas circuit to remain connected after the solenoid valve loses power, continuously provide power for the electric coupler connection, and ensure the reliability of the electric coupler connection during operation. The solenoid valve has a manual operation function, which can change the on-off of its gas circuit by operating with buttons or other tools, and can also achieve the connection and disconnection of the electric coupler when the EMU is powered off.

[0033] The plate-type pulse two-position five-way solenoid valve 2 is used to control the on-off of the electric coupler gas circuit, ensuring that the gas circuit is maintained after the solenoid valve loses power, and improving the reliability of the electric coupler connection. The plate-type pulse two-position five-way solenoid valve 2 has a manual operation function, which can realize the connection and disconnection of the electric coupler when the EMU is powered off; the plate-type pulse two-position five-way solenoid valve 2 electric coupler connection and disconnection gas circuits are mutually exclusive, which can avoid the control logic error of the independent connection solenoid valve and disconnection solenoid valve being energized at the same time.

[0034] The plate-type pulse two-position five-way solenoid valve 2 uses electromagnetic force to control the position of the valve core, which can achieve precise control of the electric coupler gas circuit, ensure the stability and reliability of the coupler during the connection and separation process, and avoid failures or accidents caused by improper gas circuit control. When the control electromagnet is energized, the plate-type pulse two-position five-way solenoid valve 2 can respond quickly to achieve rapid on and off of the electric coupler gas circuit, which is of great significance for improving train operation efficiency and reducing parking time. Compared with the two-position three-way solenoid valve, the plate-type pulse two-position five-way single electric control solenoid valve 2 can automatically maintain the on-off state of the gas circuit when the power is off, and does not need to be continuously energized to keep the gas circuit open.

[0035] In some embodiments, see Figure 1 The output end of the mechanical coupler disconnecting solenoid valve 3 is connected to one end of the mechanical coupler disconnecting air circuit; The other end of the mechanical coupler uncoupling air path is connected to the uncoupling cylinder of the mechanical coupler.

[0036] The introduction of the mechanical coupler uncoupling solenoid valve 3 enables the uncoupling operation of the coupler to be achieved through the switch control of the solenoid valve, thereby greatly improving the convenience of operation. Compared with the traditional manual uncoupling method, the solenoid valve control not only reduces the manpower demand, but also improves the operation efficiency.

[0037] In some embodiments, see Figure 1, a positive contact of the microcomputer output signal device 1 is respectively connected to the electrical coupler connection control end of the plate-type pulse two-position five-way solenoid valve 2, the electrical coupler disconnection control end of the plate-type pulse two-position five-way solenoid valve 2 and the positive line of the mechanical coupler disconnection solenoid valve 3; A negative contact of the microcomputer output signal device 1 is connected to the negative line of the electrical circuit of the plate-type pulse two-position five-way solenoid valve 2 and the mechanical coupler uncoupling solenoid valve 3.

[0038] Compared with the prior art in which only positive contacts are set on the positive line, the present invention optimizes the circuit principle of the automatic coupler control device and adds a negative contact of the microcomputer output signal device 1 on the negative line of the electrical circuit of all solenoid valves. Only when the microcomputer output signal device 1 makes the contacts on the positive and negative lines of the solenoid valves closed at the same time, all the solenoid valves can be operated to avoid the single-point failure of the microcomputer output signal device 1 that causes the accidental conduction failure of the mechanical coupler uncoupling solenoid valve 3.

[0039] The negative line of the automatic coupler control solenoid valve is connected in series with a contact controlled by a microcomputer output signal device. When the microcomputer output signal device 1 is used, the contacts on the positive and negative lines of the control solenoid valve are closed to drive the solenoid valve to operate, thereby avoiding abnormal operation of the automatic coupler caused by a single point failure of the microcomputer output signal device 1.

[0040] In some embodiments, see Figure 1 and Figure 3 , further comprising a gas circuit board 7, a protective cover 8 and a connector 9; The plate-type pulse two-position five-way solenoid valve 2, the mechanical coupler disconnecting solenoid valve 3, the mechanical coupler air circuit cut-off plug 4 and the electrical coupler air circuit cut-off plug 5 are all plate-type mounted on the air circuit board 7; The cross-sectional area of ​​the protective cover 8 is larger than the cross-sectional area of ​​the gas circuit board 7. The protective cover 8 is correspondingly connected to the gas circuit board 7 to cover all components on the gas circuit board 7. A connector 9 is provided on the outside of the protective cover 8 for connecting the circuit; The gas circuit board 7 is provided with a pipe thread for connecting the gas circuit.

[0041] The plate-type pulse two-position five-way solenoid valve 2, the electric coupler gas circuit shutoff valve 3, the mechanical coupler disconnection solenoid valve 4, and the mechanical coupler gas circuit shutoff valve 5 are all plate-type installation structures, which are installed on the gas circuit board 7 using fasteners. The connector 9 is the external interface of the automatic coupler control device circuit and is installed on the protective cover 8. The automatic coupler control components are modularly installed through the gas circuit board 7, the external circuit interface adopts the form of connector 9, and the pipeline interface adopts standard pipe threads to achieve rapid connection of pipelines and circuits.

[0042] The automatic coupler control module is equipped with a protective cover 8 which is fixed to the gas circuit board 7 by bolts to improve the protection level of the module to adapt to more complex use environments. The automatic coupler control module is provided with a connector 9 circuit interface, and the gas circuit board 7 is provided with a standard pipe thread as a gas circuit interface to achieve quick connection of pipelines and circuits. A muffler is provided on the exhaust hole of the magnetic valve of the gas circuit board 7, which is connected by threads to reduce exhaust noise. The automatic coupler control device adopts an independent functional module design and is not integrated with other functional modules, which is convenient for optional installation.

[0043] The present invention proposes a method for controlling the automatic coupler control device of a power centralized EMU, please refer to Figure 2 ,include, The positive contact and negative contact of the microcomputer output signal device 1 are closed at the same time, and an electrical connection signal, an electrical disconnection signal and a mechanical disconnection signal are generated; Based on the electrical coupling signal, the electrical coupler coupling control end of the plate-type pulse two-position five-way solenoid valve 2 is energized to control the compressed air to enter the push cylinder of the push mechanism, and the electrical coupler is coupled according to the push cylinder of the push mechanism; Based on the electrical disconnection signal, the electrical coupler disconnection control end of the plate-type pulse two-position five-way solenoid valve 2 is energized, and the compressed air is controlled to enter the push cylinder of the push mechanism, and the electrical coupler is disconnected according to the push cylinder of the push mechanism; Based on the mechanical uncoupling signal, the mechanical coupler uncoupling solenoid valve 3 is energized to control compressed air to enter the uncoupling cylinder of the mechanical coupler, and the mechanical coupler is uncoupled according to the uncoupling cylinder of the mechanical coupler.

[0044] The present invention can quickly respond to the needs of coupling and uncoupling of EMUs, significantly shorten the time of coupling and uncoupling of couplers, thereby greatly improving the operating efficiency of EMUs at stations, reducing manual intervention, avoiding operational delays and errors caused by human factors, and further improving the smoothness of the overall operating process. The present invention ensures that couplers are coupled and uncoupled at the right time, effectively avoiding safety hazards caused by improper operation or inaccurate timing.

[0045] In some embodiments, see Figure 2 Based on the electrical coupling signal, the electrical coupler coupling control end of the plate-type pulse two-position five-way solenoid valve 2 is energized to control compressed air to enter the push cylinder of the push mechanism. The steps of coupling the electrical coupler according to the push cylinder of the push mechanism include: Based on the electrical coupling signal, the electrical coupling control end of the electrical coupling control end of the plate-type pulse two-position five-way solenoid valve 2 is energized; The compressed air is controlled to reach the rear end of the push cylinder of the push mechanism through the electric coupler connection air path, and the compressed air in the electric coupler disconnection air path in the front end of the push cylinder of the push mechanism is discharged; The electric hook at the front end of the pushing cylinder of the pushing mechanism extends out.

[0046] During automatic coupler coupling, after the mechanical coupler coupling is completed, the microcomputer output signal device 1 controls the plate-type pulse two-position five-way solenoid valve 2, the electric coupler coupling control end is energized, and at the same time controls the negative line of the power supply to be closed, and the compressed air reaches the rear end of the pushing cylinder of the pushing mechanism through the electric coupler coupling air circuit. At the same time, the compressed air in the electric coupler uncoupling air circuit is discharged to the atmosphere, so that the electric coupler is extended to complete the coupling. After the coupling is completed, the solenoid valve loses power and the air circuit remains connected, ensuring that the electric coupler is reliably connected during the operation of the train.

[0047] Compressed air is used as a power source. Its discharge can accurately control the extension and retraction speed and strength of the push cylinder, thereby ensuring that the extension of the electric coupler is both quick and accurate. As a clean energy source, the use of compressed air will not produce additional pollutant emissions and meets environmental protection requirements. At the same time, by accurately controlling the discharge of compressed air, energy can be maximized and operating efficiency can be improved. The compressed air power system is relatively simple and has low maintenance costs. Once a fault occurs, it is also easier to diagnose and repair. The rapid extension of the electric coupler can quickly complete the connection between the EMU carriages, reduce the time of the coupling operation, and improve the overall operational efficiency. After the electric coupler is extended, it can be firmly connected to ensure that it will not loosen or fall off during driving, thereby improving the safety and stability of driving.

[0048] In some embodiments, see Figure 2 Based on the electrical disconnection signal, the electrical coupler disconnection control end of the plate-type pulse two-position five-way solenoid valve 2 is energized to control compressed air to enter the push cylinder of the push mechanism. The steps of disconnecting the electrical coupler according to the push cylinder of the push mechanism include: Based on the electrical disconnection signal, the electrical coupler disconnection control terminal of the plate-type pulse two-position five-way solenoid valve 2 is energized; The compressed air is controlled to reach the front end of the push cylinder of the push mechanism through the electric coupler uncoupling air path, and the compressed air in the electric coupler coupling air path in the rear end of the push cylinder of the push mechanism is discharged; The electrical coupler at the front end of the pushing cylinder of the pushing mechanism is disengaged.

[0049] When the automatic coupler is uncoupled, the microcomputer output signal device 1 controls the plate-type pulse two-position five-way solenoid valve 2, the electric coupler uncoupling control end is energized, and at the same time controls the negative line of the power supply to be closed, and the compressed air reaches the front end of the pushing cylinder of the pushing mechanism through the electric coupler uncoupling air path. At the same time, the compressed air in the electric coupler connecting air path is discharged to the atmosphere, causing the electric coupler to retract.

[0050] The action of discharging compressed air and retracting the electric coupler can be completed in a short time, thereby improving the response speed of the entire coupler control system. This enables the EMU to enter the working state more quickly when separating, reducing waiting time. By accurately controlling the action of discharging compressed air and retracting the electric coupler through the control system, safety hazards caused by human misoperation can be avoided, and traffic accidents and casualties caused by operational errors can be reduced. During the coupler separation process, the impact and wear on the vehicle structure can be reduced, the service life of the vehicle can be extended, and the maintenance cost can be reduced. After the compressed air is discharged, the pressure in the cylinder is maintained, so that the electric coupler can maintain a stable position and posture during the retraction process.

[0051] In some embodiments, see Figure 2 Based on the mechanical uncoupling signal, the mechanical coupler uncoupling solenoid valve 3 is energized to control compressed air to enter the uncoupling cylinder of the mechanical coupler. The steps of uncoupling the mechanical coupler according to the uncoupling cylinder of the mechanical coupler include: Based on the mechanical disconnection signal, the mechanical coupler disconnection solenoid valve 3 is energized; The compressed air is controlled to reach the mechanical coupler uncoupling cylinder through the mechanical uncoupling air path, and air is filled in the mechanical coupler uncoupling cylinder to uncouple the mechanical coupler.

[0052] At the same time, the microcomputer output signal device 1 controls the mechanical coupler uncoupling solenoid valve 3 to be energized, and at the same time controls the negative line of the power supply to be closed, and the compressed air reaches the mechanical coupler uncoupling cylinder through the mechanical coupler uncoupling air path to be filled with air, and the mechanical coupler is unhooked.
