These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0043] As mentioned in the background section, air testing is a crucial step in the assembly and commissioning of high-speed trains. Air testing primarily involves testing the train's pneumatic systems to ensure their proper functioning. This includes checking the braking system, door operation, and other pneumatic equipment such as the toilet ventilation system.

[0044] When adding or removing vehicles, the first step is to confirm the unobstructed flow of the main air duct, as this directly affects the overall function of the pneumatic system. It is also necessary to conduct a test run to check if the air pressure in the braking system is within the normal range, ensuring the brakes can respond quickly when needed; check the pneumatic door opening and closing system to ensure it operates normally under different conditions, including manual operation in emergencies; and ensure the restroom ventilation system is functioning properly to maintain good air quality and comfort.

[0045] Since the installation and removal of the air testing device and the coupler end are repeated, there is an urgent need for an air testing device that can simplify the installation and removal process, reduce device downtime, and improve work efficiency.

[0046] In view of this, the present application provides a train set air testing device. Through the design of the support structure, the installation and disassembly process of the train set air testing device becomes simpler, reducing operation steps and time. Since the state of the support structure can be quickly switched, the device downtime is reduced and the overall operation efficiency is improved. The design of the device allows for adjustment in different states, changing the installation height to adapt to different operating needs and environmental conditions.

[0047] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] refer to Figure 1 This application provides a test air device for high-speed trains, including an air supply component 100, a guide component 200, and a clamping component 300.

[0050] The gas supply component 100 and the clamping component 300 are spaced apart. The gas supply component 100 can be used to connect to a gas source. The gas supply component 100 has an air outlet 110 on the side facing the clamping component 300.

[0051] The guide member 200 passes through the gas delivery member 100 and the clamping member 300. The guide member 200 is provided with a support structure 400, which is movably disposed on the guide member 200.

[0052] When the support structure 400 is in the first state, the support structure 400 abuts against the surface of the gas delivery component 100 facing the clamping component 300, and the gas delivery component 100 is fixed to the guide component 200 through the support structure 400.

[0053] When the support structure 400 is in the second state, the support structure 400 does not abut against the surface of the air supply member 100 facing the clamping member 300, and the air supply member 100 can slide relative to the guide member 200.

[0054] It is understood that the air supply component 100 is used to connect to the air source and, through its air outlet 110, connects to the air duct of the train car, delivering gas to the pneumatic system to be tested. The air supply component 100 serves as the gas input end, ensuring a stable supply of air to the test air device for effective pneumatic testing. The guide component 200 provides guidance and support, ensuring that the air supply component 100 and the clamping component 300 maintain correct alignment and positioning during installation and disassembly, preventing misoperation. The clamping component 300, together with the air supply component 100, secures the train test air device to the coupler end of the train set. The relative positions of the clamping component 300 and the air supply component 100 can be adjusted via the guide component 200. To accommodate the coupler end, it provides a stable fixing force, ensuring that the air testing device does not shift or loosen during testing, thus guaranteeing the accuracy and safety of the test. The support structure 400 can be movably mounted on the guide member 200 and has two states: a first state and a second state. In the first state, the support structure 400 abuts against the surface of the air supply member 100, fixing the air supply member 100 to the guide member 200 through the support structure 400, ensuring the stability of the device. In the second state, the support structure 400 does not abut against the surface of the air supply member 100, allowing the air supply member 100 to slide relative to the guide member 200, facilitating quick installation and disassembly.

[0055] Thus, through the design of the support structure 400, the installation and dismantling process of the EMU test air device becomes simpler, reducing operation steps and time; because the state of the support structure 400 can be quickly switched, the device downtime is reduced and the overall operation efficiency is improved; the design of the device allows for adjustment in different states, changing the installation height, and adapting to different operating needs and environmental conditions.

[0056] During use, first adjust the support structure 400 to the second state so that the air supply component 100 can slide relative to the guide component 200; adjust the support structure 400 to the first state so that it abuts against and is fixed to the air supply component 100; fix the clamping component 300 to the end of the train coupler to complete the fixing of the train test air device.

[0057] Connect the air source to the air supply component 100, align the air outlet 110 with the air supply pipe of the train car, and begin the inflation test.

[0058] After the test is completed, the support structure 400 is adjusted to the second state so that the air supply component 100 can slide. The air supply component is removed from the guide component 200, the clamping component 300 is released, and the train test air device is removed.

[0059] Specifically, the air supply component 100 has a plate-mounted structure, and the clamping component 300 has a clearance hole 320. The clearance hole 320 can adapt to the shape of the coupler end, so that the air supply component 100 and the clamping component 300 can be better fixed at the coupler end.

[0060] Reference 2 and Figure 3 In some possible implementations, the support structure 400 includes a plurality of fixing heads 410 that can be close to or away from the guide member 200.

[0061] When the support structure 400 is in the first state, the fixing head 410 is away from the guide member 200 and abuts against the gas supply member 100; when the support structure 400 is in the second state, the fixing head 410 is close to the guide member 200 and disengages from the gas supply member 100.

[0062] It can be seen that the main function of the support structure 400 is to fix or release the gas delivery component 100 on the guide 200 by moving the fixing head 410. When the fixing head 410 moves away from the guide 200, it abuts against the gas delivery component 100, and the gas delivery component 100 cannot move on the guide 200 in the direction close to the support structure 400. The position of the gas delivery component 100 is fixed, ensuring the stability of the device during testing. When the fixing head 410 moves close to the guide 200, it disengages from the gas delivery component 100, which is equivalent to opening the path for the gas delivery component 100 to move on the guide 200 in the direction close to the support structure 400, allowing the gas delivery component 100 to slide relative to the guide 200, which facilitates quick installation and disassembly.

[0063] With the design of the fixing head 410, the support structure 400 can quickly switch states, simplifying the installation and disassembly process.

[0064] In some possible implementations, the support structure 400 includes a control unit 420 and a plurality of links 430, which are correspondingly arranged with a plurality of fixing heads 410.

[0065] The first end of the fixing head 410 is rotatably connected to the guide member 200, and the second end of the fixing head 410 can approach or move away from the guide member 200.

[0066] The control unit 420 is rotatably connected to the first end of the connecting rod 430, and the second end of the connecting rod 430 is rotatably connected to the corresponding fixed head 410. The control unit 420 can drive the fixed head 410 to rotate relative to the guide member 200 around the first end of the fixed head 410 through the connecting rod 430.

[0067] It is known that the control unit 420 is the core component of the support structure 400 that can be activated, and is used to operate and adjust the position of the fixed head 410; through the movement of the connecting rod 430, the control unit 420 can drive the fixed head 410 to rotate around its first end, thereby realizing the position adjustment.

[0068] Through the design of the control unit 420 and the connecting rod 430, the support structure 400 can quickly adjust the position of the fixing head 410, simplifying the installation and disassembly process.

[0069] In some possible implementations, the guide member 200 is provided with a guide groove 210, the extension direction of which is parallel to the axial direction of the guide member 200.

[0070] The control unit 420 is movably disposed in the guide groove 210 along the axial direction of the guide member 200.

[0071] The guide member 200 is provided with a connecting groove 220, which is connected to the guide groove 210, and the connecting rod 430 can be movably disposed in the connecting groove 220.

[0072] It is understood that the guide groove 210 is used to accommodate and guide the movement of the control unit 420, ensuring that the control unit 420 can move smoothly along the axial direction of the guide member 200. The guide groove 210 provides a clear movement path, making the operation of the control unit 420 more precise and smooth; the connecting groove 220 is used to accommodate and guide the movement of the connecting rod 430. The connecting groove 220 is connected to the guide groove 210, allowing the connecting rod 430 to move within it. Through this design, the connecting rod 430 can accurately transmit movement to the fixed head 410 under the drive of the control unit 420, realizing the adjustment of its position.

[0073] It should be noted that the connecting groove 220 is also used to accommodate the fixing head 410. When the support structure is in the second state, the fixing head 410 can be accommodated in the connecting groove 220 to avoid hindering the movement of the gas delivery component 100 on the guide component 200.

[0074] The design of the guide groove 210 and the connecting groove 220 provides a clear motion path, making the operation of the control unit 420 and the connecting rod 430 simpler and more efficient; through the precise motion path design, the motion accuracy of the control unit 420 and the connecting rod 430 is ensured, and the reliability of the air test device is improved.

[0075] In some possible implementations, in the axial direction of the guide 200, the first end of the connecting rod 430 is closer to the first end of the fixing head 410 relative to the second end of the connecting rod 430; the angle between the connecting rod 430 and the corresponding fixing head 410 is less than 90 degrees.

[0076] It can be understood that the geometric relationship between the connecting rod 430 and the fixed head 410 enables the connecting rod 430 to effectively transmit the movement of the control unit 420 to the fixed head 410 within a small range of motion, ensuring that the fixed head can be fabricated on the air supply component 100 in the first state of the support structure; at the same time, by reducing the included angle, the connecting rod 430 can generate a large torque within a short movement distance, thereby more effectively adjusting the position of the fixed head 410.

[0077] Because the angle between the connecting rod 430 and the fixed head 410 is less than 90 degrees, the device can operate effectively within a small range of motion, reducing adjustment time and improving work efficiency. The smaller angle design allows the connecting rod 430 to generate greater torque within a shorter movement distance, enhancing the control force on the fixed head 410. This design reduces the space occupied by the device, enabling the test air device to operate efficiently in a limited space.

[0078] In some possible implementations, the support structure 400 is provided with a reset part 440, which is disposed on the guide member 200.

[0079] The reset unit 440 is connected to the control unit 420. The reset unit 440 is used to apply a force to the fixed head 410 that brings it closer to the gas delivery unit 100 through the control unit 420.

[0080] It is understood that the reset part 440 applies a force to the fixing head 410 through the control part 420, causing the fixing head 410 to abut against the air supply component 100. This design allows the fixing head 410 to automatically abut against the air supply component 100 (the first rotation state of the support structure) during operation, providing a stable fixing effect. Through the movement of the control part 420, the reset part 440 can effectively transmit the force to the fixing head 410, ensuring that it maintains a stable abutment state during operation.

[0081] The design of the reset part 440 enables the fixed head 410 to automatically reset and abut against the gas supply component 100 after operation, reducing the need for manual adjustment; through automatic reset and stable force application, the operation steps and time are reduced, and the overall operation efficiency is improved; the continuous force provided by the reset part 440 ensures the stable abutment between the fixed head 410 and the gas supply component 100, enhancing the stability and reliability of the device.

[0082] Specifically, the reset part 440 is a spring.

[0083] During use, the control unit 420 is pressed downward along the axial direction of the guide member 200. The control unit 420 presses down the reset unit 440, applying force to the reset unit 440. The control unit 420 drives one end of the connecting rod 430 to move downward. The angle between the connecting rod 430 and the corresponding fixing head 410 gradually decreases, so that the fixing head 410 is housed in the connecting groove 220. The fixing head 410 is disengaged from the air supply member 100. The air supply member 100 is moved upward along the axial direction of the guide member 200. The air supply member 100 is removed from the guide member 200, and the transfer member 300 is removed from the guide member 200, thus completing the removal of the EMU test air device.

[0084] When the control unit 420 is no longer pressed downward in the axial direction of the guide member 200, the reset unit 440 restores its length through elasticity and pushes the control unit 420 upward. The control unit 420 drives one end of the connecting rod 430 to move upward. The angle between the connecting rod 430 and the corresponding fixed head 410 gradually decreases. The fixed head 410 abuts against the air supply member 100, and the position of the air supply member 100 on the guide member 200 is fixed.

[0085] In some embodiments, at least a portion of the control unit 420 can extend out of the guide 200 to facilitate the application of force to the control unit 420.

[0086] To prevent accidental activation of the control unit 420, an anti-touch portion 230 can be provided at the end of the guide member 200 where the control unit 420 extends. The anti-touch portion 230 can be a semi-annular structure that is slightly higher than the control unit 420. The anti-touch portion 230 can also be a cover that can be detachably connected to the guide member 200. It should be noted that as long as the anti-touch portion 230 can effectively shield the end of the control unit 420 that extends from the guide member 200, the structure of the anti-touch portion 230 is not subject to many restrictions in this embodiment.

[0087] In some embodiments, a push block 421 is provided at one end of the control unit 420 near the connecting rod 430. The push block 421 has a rotating groove 422 at the position corresponding to the connecting rod 430, and the connecting rod 430 is rotatably connected to the rotating groove 422.

[0088] In some embodiments, the rotating groove 422 contains ball bearings, and the connecting rod 430 is rotatably connected to the rotating groove 422 via the ball bearings.

[0089] In other embodiments, the end of the connecting rod 430 connected to the rotating groove 422 is a ball-shaped shaft, and the shape of the rotating groove 422 conforms to the shape of the ball-shaped shaft.

[0090] It should be noted that as long as the connecting rod 430 can be rotatably connected to the rotating groove 422, the embodiments of this application do not impose too many restrictions on the way the connecting rod 430 is rotatably connected to the rotating groove 422.

[0091] Specifically, the control unit 420 can be integrated with the push block 421 to increase structural strength.

[0092] In some possible implementations, the clamping member 300 is provided with a locking part 310, which is located on the side of the clamping member 300 away from the gas supply member 100, and the clamping member 300 can be fixed to the guide member 200 by means of the locking part 310.

[0093] It can be understood that the clamping part 300 is fixed to the guide part 200 by the locking part 310, ensuring that the device remains stable during the test and preventing displacement or loosening.

[0094] Specifically, the locking part 310 is threadedly connected to the guide part 200.

[0095] By using the locking part 310, the distance between the clamping part 300 and the air supply part 100 can be adjusted to adapt to the shape and height of the coupler end, making the fixing effect between the device and the coupler end more secure. It also allows the clamping part 300 to be easily removed from the guide part 200, simplifying the installation and disassembly process, reducing device downtime, and improving overall operating efficiency.

[0096] During use, the locking part 310 is separated from the guide 200, so that the clamping part 300 can be removed from the guide 200.

[0097] In some possible implementations, the guide 200 is provided with a clamping member 500, which is located on the side of the air supply member 100 away from the clamping member 300.

[0098] The clamping member 500 is threadedly connected to the guide member 200, and the clamping member 500 can closely abut against the surface of the air supply member 100 away from the clamping member 300.

[0099] It is known that the guide member 200, through its threaded connection with the clamping member 500, ensures that the clamping member 500 can stably apply pressure to keep the air supply member 100 in the correct position; the clamping member 500 can tightly abut against the surface of the air supply member 100 away from the clamping member 300, and under the action of the support structure 400, provides the necessary pressure to ensure the stable positioning of the air supply member 100, preventing the air supply member 100 from being displaced during operation due to vibration or other external forces.

[0100] The design of the clamping component 500 ensures the stability of the gas delivery component 100 during operation, preventing displacement or loosening caused by external forces, avoiding air leakage, and improving the efficiency of air testing. Through the threaded connection, the clamping component 500 can be quickly installed and adjusted, reducing operation time and improving overall work efficiency. The continuous pressure provided by the clamping component 500 ensures the reliable connection of the gas delivery component 100, enhancing the overall reliability of the device.

[0101] During use, when it is necessary to fix the EMU test air device at the end of the coupler, the air supply component 100 is threaded onto the guide component 200, the fixing head 410 abuts against the air supply component 100, and the clamping component 500 is installed on the guide component 200 to ensure that the air supply component 100 is fixed in position with the guide component 200 under the action of the clamping component 500 and the supporting structure. At the same time, the clamping component 300 is threaded onto the guide component 200, and the locking part 310 is adjusted to the position of the guide component 200 so that the clamping component 300 and the air supply component 100 can stably clamp the end of the coupler, and the EMU air pipe is connected to the air outlet 110.

[0102] When it is necessary to remove the test air device of the EMU, remove the locking part 310 and the clamping part 500 on the guide 200, remove the clamping part 300 from the guide 200, press the control part 420 to move the fixing head away from the air supply part 100, and remove the air supply part 100 from the guide 200.

[0103] It should be noted that the installation and removal steps are not unique. As long as the gas supply component 100 and the clamping component 300 can be installed reasonably, the embodiments of this application do not impose too many restrictions on the steps.

[0104] refer to Figure 2 In some embodiments, the clamping member 500 is provided with a plurality of mounting handles 510, which facilitates the application of force to the clamping member 500.

[0105] refer to Figure 4 and Figure 5 In some possible implementations, the gas delivery component 100 is provided with a connection structure 600 for communicating with a gas source.

[0106] The connection structure 600 includes a mating mounting base 610 and a connecting pipe 620. The mounting base 610 is disposed on the gas supply component 100, and the connecting pipe 620 is movable relative to the mounting base 610 in a direction that is close to or away from the gas supply component 100.

[0107] It is understood that, through the connection structure 600, the gas supply component 100 can be quickly connected to or disconnected from the gas source, ensuring that the air test can be carried out quickly; the mounting base 610 is set on the gas supply component 100, serving as the fixing and guiding base for the connecting pipe 620. The mounting base 610 provides a stable interface, enabling the connecting pipe 620 to be accurately aligned and connected, ensuring the sealing and stability of gas transmission; the mobility of the connecting pipe 620 allows the connecting pipe 620 to be quickly adjusted to connect or disconnect from the gas source, realizing rapid connection and disconnection of the gas source, simplifying the operation steps.

[0108] The movable design of the connecting pipe 620 allows the overall height of the connecting structure 600 to be adjusted, making connection and disconnection with the gas source quicker, reducing operation time, minimizing device downtime, and improving overall operating efficiency. The cooperation between the mounting base 610 and the connecting pipe 620 ensures the airtightness of gas transmission, prevents leakage, and enhances the reliability of the device.

[0109] In some possible implementations, the mounting base 610 is provided with a mounting groove 611, the connecting pipe 620 is disposed in the mounting groove 611, and the connecting pipe 620 is provided with a plurality of insertion slots 621, which are arranged sequentially at intervals.

[0110] The connection structure 600 includes a fastener 630, which is movably disposed on the mounting base 610, passes through the mounting base 610, and can be inserted into the insertion slot 621.

[0111] Understandably, the mounting base 610 provides a stable interface, and the mounting groove 611 accommodates the connecting pipe 620, ensuring that it moves and is fixed in the correct position. The mounting groove 611 ensures that the connecting pipe 620 can move smoothly within it, providing a clear path to adjust the overall height of the connection structure 600. The insertion groove 621 is used to cooperate with the fastener 630 to fix the connecting pipe 620 in the position of the mounting base 610. Multiple insertion grooves 621 are arranged sequentially at intervals, allowing the connecting pipe 620 to be fixed in different positions to adapt to different connection height requirements. The fastener 630 can be movably set in the mounting base 610, passes through the mounting base 610, and is inserted into the insertion groove 621 to achieve a stable fixation of the connecting pipe 620.

[0112] In some embodiments, the mounting base 610 is provided with a reset key mounting groove 612 along the length direction of the fixing member 630, and the fixing member 630 is provided with a limiting member 631. The limiting member 631 can move within the reset key mounting groove 612. The limiting member 631 can not only prevent the fixing member 630 from coming out of the mounting groove 611, but also automatically push the fixing member 630 into the insertion groove 621.

[0113] A reset button 640 is also provided in the reset button mounting slot 612. One end of the reset button 640 abuts against the limiting member 631, and the other end of the reset button 640 abuts against the reset button mounting slot 612. The reset button 640 can apply a force to the limiting member 631 as it approaches the mounting slot 611.

[0114] Specifically, the limiting component 631 and the fixing component 630 are integrally formed.

[0115] Specifically, the reset button 640 can be a spring.

[0116] The design of the reset button 640 ensures that the fastener 630 can automatically insert into the plug slot 621 after operation, reducing the need for manual adjustment; the multiple plug slots 621 and the automatic reset mechanism reduce operation steps and time, improving overall work efficiency; the multiple plug slots 621 provide a variety of fixing positions, enhancing the adaptability and flexibility of the connection structure 600.

[0117] When it is necessary to adjust the position of the connecting tube 620 in the mounting base 610, pull the fixing member 630 away from the connecting tube 620. The limiting member 631 applies force to the reset button 640, causing the reset button 640 to shorten and the fixing member 630 to disengage from the currently connected insertion slot 621. After adjusting the position of the connecting tube 620 in the mounting base 610, release the fixing member 630. The reset button 640, due to its elastic extension, pushes the limiting member 631, which in turn drives the fixing member into the insertion slot 621 at the required fixed height.
