Description

Technical Field

[0001] This invention relates to the field of EMU coupler continuity testing technology, and in particular to an EMU coupler continuity testing device. Background Technology

[0002] EMU (Electric Multiple Unit) trains are rail vehicles composed of multiple self-powered carriages, unlike traditional locomotive-hauled trains. The trains consist of a combination of powered and unpowered carriages, resulting in smooth start-stop and acceleration, high speed, and excellent passenger comfort. The modular design of the trains allows for flexible assembly, and the number of carriages can be adjusted according to capacity requirements. Running on dedicated tracks, they feature low energy consumption, low noise, and high safety, making them the main rail transit tool for intercity and long-distance passenger transport, and are widely used on major passenger lines across the country.

[0003] The EMU coupler continuity test is a continuity test conducted on the electrical connection circuit of the coupler during EMU coupling or maintenance. The test uses specialized equipment to connect to the coupler electrical interface to test the continuity and insulation status of each core wire, communication circuit and safety circuit, and to check for faults such as broken wires, short circuits or poor contact. It ensures that electrical signals, braking commands and control networks can be reliably transmitted after mechanical coupling. The test is carried out according to standard procedures and is a key test item to ensure synchronous control and driving safety during coupled operation.

[0004] Currently, the industry uses manual labor with multimeters to complete coupler continuity tests. The operation mode involves multiple people working together across areas to check pin by pin. The overall process is cumbersome and sequential. Testing a single EMU is time-consuming and requires a large amount of manpower, which restricts the improvement of maintenance capacity. During the operation, it is necessary to repeatedly plug and unplug shorting wires to short-circuit the pins, which can easily cause mechanical deformation and wear of the electrical cabinet plugs and sockets, leading to subsequent train malfunctions. At the same time, manual checking of pins and transmission of information are prone to problems such as incorrect connection, missed detection, and misjudgment, making it impossible to control the test quality stably. The test requires personnel to be on duty for a long time in the electrical cabinet area inside the train, which is without power, hot and poorly ventilated, posing health and safety hazards to personnel. Moreover, the existing similar testing equipment cannot be adapted to the EMU maintenance conditions without power, nor can it complete the continuity test of the entire circuit harness from the coupler to the electrical cabinet inside the train, resulting in poor on-site adaptability.

[0059] The working principle of the train coupler continuity test device provided by this invention is as follows:

[0060] The device consists of two separate components: the execution device 1 and the control and testing device 4. Both are independently powered by built-in lithium batteries, making it suitable for the power-off operation conditions of Level 4 maintenance on EMU trains. Before operation, it is confirmed that the EMU is in a power-off state. The execution device 1 is first placed in the electrical cabinet area inside the train. Using the M12 Ethernet connector 102 and DB9 interface 103, six sets of plugs to be tested are connected via M12 type connecting cable 8 and DB9 type connecting cable 7, respectively: ETBN-X2, ETBN-X4, gateway module 1-WTB1, gateway module 1-WTB3, carriage controller-X20, and carriage controller-X14. Then, the grounding interface 104 is reliably connected to the EMU train body ground wire via a cable, completing the one-time centralized connection of the wiring harness inside the train.

Its grounding interface 402 is connected to the train body ground wire via grounding connection cable 10. The test interface 40... 5. Connect the test cable 9 to the electrical coupler connector pins. The operator initiates a test command at the control test device 4. The command is transmitted to the execution device 1 via the wireless communication module. The PLC selection module inside the execution device 1 acts according to the command, short-circuiting the specified pin to be tested to the car body ground wire. At the same time, the continuity detection module inside the control test device 4 collects the electrical signal of the corresponding pin of the electrical coupler in real time to determine the continuity of the wiring harness. If the circuit is continuous, the corresponding area of ​​the touch display module of the control test device 4 lights up with a green indicator. If the circuit is broken, it maintains the original state. The device has a built-in pin mapping relationship and completes the detection of all pins in sequence according to the preset correspondence. The entire process does not require personnel to be on duty in the car, nor does it require manual short-circuiting of each pin or cross-area communication. After all pin tests are completed, disconnect each connecting cable and device in sequence, restore the original joint and coupler protection structure of the EMU, and the entire continuity test operation is completed.

[0061] Compared with related technologies, the train coupler conduction test device provided by the present invention has the following advantages:

[0062] This design, based on the separate structure of the execution device 1 and the control and testing device 4, and combined with the docking methods of various interfaces and supporting cables, comprehensively solves many defects of existing testing technologies. First, the M12 Ethernet connector 102 and DB9 interface 103 can connect all the plugs under test at once, eliminating the need for manual pin-by-pin insertion and removal using shorting wires, effectively avoiding mechanical damage such as deformation and wear to the electrical cabinet plugs, and preventing poor contact faults caused by this. Second, the execution device 1 remotely completes the pin shorting, and together with the control and testing device 4, it achieves single-end control, eliminating the need for multiple personnel to be on duty in different areas and communicate via walkie-talkie. The original three-person operation mode can be reduced to one or two people, and the test time for a single group is shortened from 80 minutes to 35 minutes, greatly improving work efficiency. Firstly, it reduces labor costs. Secondly, the device has a built-in standard pin mapping relationship, which, together with the automatic signal acquisition and visualization display function of the control and testing equipment 4, eliminates the need for manual pin checking, multimeter reading, and result judgment, completely avoiding problems such as incorrect connection, missed detection, and misjudgment, and ensuring test accuracy. At the same time, after the execution device 1 is wired, no personnel need to stay in the vehicle, avoiding the health and safety risks caused by working in a high-temperature confined space. In addition, the execution device 1 and the control and testing equipment 4 are powered by built-in lithium batteries. The grounding wire interface 104, grounding wire interface 402, test interface 405 and various supporting cables are adapted to the existing structure of the EMU, without the need for external power supply or modification of the vehicle body. It is perfectly matched to the EMU's non-powered maintenance conditions and can be directly promoted and applied at the maintenance site of various EMU depots.

[0063] Second Embodiment

[0064] Please refer to the following: Figures 11-12 , Figure 11 This is a schematic diagram of the second embodiment of the train coupler conduction test device provided by the present invention. Figure 12 Provided for the present invention Figure 11 The enlarged view at point B shows a train coupler conduction test device based on the first embodiment of this application. The second embodiment of this application proposes another train coupler conduction test device. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0065] Specifically, the difference between the train coupler conduction test device provided in the second embodiment of this application and the one described herein is as follows: Please refer to... Figure 11 The bottom of the execution device 1 is equipped with a base plate 11, the top of the base plate 11 is equipped with a limit frame 12, the top of the base plate 11 is equipped with a support component 13, and the top of the support component 13 is equipped with a plurality of limit components 14.

[0066] The support component 13 is located between the base plate 11 and the actuator 1. The limiting frame 12 has the same bottom size as the actuator 1 and is used to limit the actuator 1.

[0067] Please refer to Figure 11 and Figure 12 The support assembly 13 includes a card holder 131 and a support frame 132. The card holder 131 is clipped onto the top of the execution device 1, and the support frame 132 is mounted on the back of the card holder 131.

[0068] The bottom of the support frame 132 is connected to the top of the base plate 11.

[0069] Please refer to Figure 11 and Figure 12 The limiting component 14 includes a support rod 141, a soft pad 142, a limiting buckle 143, and a tray 144. The support rod 141 is used to install the tray 144 on the top of the support component 13. The limiting buckle 143 is installed on the top of the tray 144, and the soft pad 142 is installed inside the limiting buckle 143.

[0070] The size of the limit buckle 143 corresponds to the cable.

[0071] Compared with related technologies, the train coupler conduction test device provided by the present invention has the following advantages:

[0072] To enhance the stability of the connection between the DB9 type connecting cable 7, the M12 type connecting cable 8, and the actuator 1, this device adds a base plate 11 with a limiting frame 12 to the bottom of the actuator 1. The base plate 11 serves as the support base for the actuator 1, and the limiting frame 12 provides initial positioning of the actuator 1, preventing displacement or tipping during use. Between the actuator 1 and the base plate 11, multiple sets of limiting components 14 are sequentially assembled using a support component 13. The support component 13 securely mounts the limiting components 14 in designated positions, ensuring that each set of limiting components 14 is distributed along the routing paths of the DB9 type connecting cable 7 and the M12 type connecting cable 8. During the actual coupler connection test, the operator connects the DB9 type connecting cable 7 to the DB9 interface 103 of the actuator 1 and the M12 type connecting cable 8 to the M12 Ethernet connector of the actuator 1. 102. Next, insert the cable sections of the two cables into the corresponding limiting buckles 143 of the limiting components 14. The limiting buckles 143 will wrap and support the cable sections, continuously providing upward support for the cables, sharing the weight of the cables themselves and the external forces generated by shaking and pulling during operation, effectively reducing the direct external force acting on the connection between the connector and the interface. This structure is simple and practical. The base plate 11, together with the limiting frame 12, can fix the overall position of the execution device 1. The support component 13 ensures that the limiting component 14 is installed securely. The constraint and support of the limiting buckles 143 on the cable sections can greatly reduce the probability of cable connectors becoming loose or falling off, preventing problems such as signal interruption and poor contact due to unstable connection. This not only ensures the connection stability of the DB9 type connecting cable 7, the M12 type connecting cable 8 and the execution device 1, but also makes the operation of the entire coupler continuity test device more reliable and extends the service life of the cable and equipment interface.

[0073] Third Embodiment

[0080] To facilitate the placement and use of the control and testing equipment 4 during the experiment, this device adds a docking component 15 to the back of the control and testing equipment 4. The docking component 15 has two hooks 152 on its back. During operation, the control and testing equipment 4 can be directly suspended from the shelf in the work area using the hooks 152, eliminating the need to hold the equipment or place it haphazardly. This greatly simplifies various operations for the staff. Simultaneously, the magnetic plates 154 on the docking component 15 generate an attractive force, further securing the suspension and effectively preventing the control and testing equipment 4 from shaking or slipping, thus improving the overall stability of the equipment placement. Furthermore, during the control and testing... The side of the equipment 4 is also equipped with a fixing strip 16 with a buckle 17. During the test, excess cables can be directly inserted into the buckle 17 for temporary storage and fixation. With the limiting effect of the buckle 17, the position of the cables can be firmly restrained, preventing the cables from hanging down randomly. This prevents the cable joints from directly contacting the ground, protecting the joints from bumps and stains, and also preventing the cables from getting tangled and pulled. This makes the on-site wiring more neat and orderly. The overall structural design is simple and practical, taking into account the multiple needs of equipment placement, ease of operation and cable protection, optimizing on-site working conditions and ensuring that the coupler conduction test is carried out smoothly and orderly.

[0081] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
