Description

Technical Field

[0001] This utility model relates to the technical field of EMU maintenance training equipment, specifically a demonstration device for EMU brake adjusters. Background Technology

[0002] As a core component in the EMU braking system that enables automatic compensation of brake shoe clearance, the brake adjuster's dynamic working state is directly and closely related to the stability of the brake cylinder piston stroke. During EMU operation, the brake shoes wear continuously due to long-term friction with the wheel tread. Without precise adjustment by the brake adjuster, the clearance between the brake shoes and the wheel will gradually increase, directly causing the brake cylinder piston stroke to exceed the safety standard range. Therefore, the working state of the brake adjuster is not only the core guarantee for maintaining the stability of the brake cylinder piston stroke, but also a key link that directly determines the braking safety of the EMU and ensures the order of railway transportation. Its performance reliability and adjustment accuracy are of irreplaceable importance to train operation safety. To ensure that maintenance personnel and trainees can accurately grasp the working logic of the brake adjuster, it is necessary to simulate real working conditions through a dedicated demonstration device.

[0003] In the existing technology, most existing devices are designed as "one-to-one" devices, which can only be adapted to a certain type of brake control unit (such as only supporting ST2-250 or only supporting ST1-600). When different types of brake control units need to be demonstrated, the entire structure of the device needs to be disassembled and modified. This is not only cumbersome and time-consuming, but also prone to reduced demonstration accuracy due to modification errors. It is also incompatible with the two mainstream brake control unit models of EMU trains. Utility Model Content

[0004] The purpose of this utility model is to provide a demonstration device for a high-speed train brake regulator, in order to solve the problem that the existing brake regulator demonstration devices mentioned in the background art are mostly "one-to-one" designs, only compatible with a single model. When switching to demonstrate different models, it is necessary to disassemble and modify the overall structure of the device, which is not only cumbersome and time-consuming, but also prone to reducing the demonstration accuracy due to modification errors, and cannot be compatible with the two mainstream brake regulator models of high-speed trains.

The two sets of the first stop block body and the second stop block body are symmetrically distributed on both sides of the gate regulator body. The platform has through slots opened at corresponding positions of the first stop block body and the second stop block body. Both sets of the first stop block body and the second stop block body are located in the through slots of the platform.

[0009] In a preferred embodiment of this technical solution, a long mounting slot is provided on the support frame, and the mounting frame is installed in the long mounting slot on the support frame by bolts.

[0010] Based on the preferred embodiment of this technical solution, the padding assembly includes a base fixedly connected to the platform, a sixth pneumatic telescopic rod body, a fifth pneumatic telescopic rod body, a fourth pneumatic telescopic rod body, and a third pneumatic telescopic rod body, all sequentially fixedly connected to the base, a 120mm thick padding body fixedly connected to the telescopic end of the sixth pneumatic telescopic rod body, a 60mm thick padding body fixedly connected to the telescopic end of the fifth pneumatic telescopic rod body, a 20mm thick padding body fixedly connected to the telescopic end of the fourth pneumatic telescopic rod body, a 10mm thick padding body fixedly connected to the telescopic end of the third pneumatic telescopic rod body, and 10mm thick padding buttons fixedly connected to the same side of the platform and the controller, including a 10mm thick padding button, a 20mm thick padding button, a 60mm thick padding button, and a 120mm thick padding button. The air supply system is pneumatically connected to the sixth pneumatic telescopic rod body. The retractable rod body, the fifth pneumatic telescopic rod body, the fourth pneumatic telescopic rod body, and the third pneumatic telescopic rod body are all electrically connected to the controller. The thickness 10 shim button, the thickness 20 shim button, the thickness 60 shim button, and the thickness 120 shim button are all electrically connected to the controller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By replacing the second connecting rod with the first connecting rod of different lengths and using several sets of pins, it is possible to connect with different models of gate controllers, which can quickly adapt to various gate controller models. At the same time, by adjusting the limit requirements of the limit components according to the simulated model, there is no need to disassemble and modify the overall structure of the device, which effectively improves the adaptability of the device to different simulation scenarios, simplifies the operation process, reduces structural damage and error risks caused by frequent disassembly, and ensures the stability and convenience of the demonstration process.

[0015] 2. By designing the padding assembly to include padding bodies of different thicknesses and corresponding pneumatic telescopic rod bodies, and with the drive of the air source system and the control of independent padding buttons, operators can precisely trigger the extension of padding bodies of single or combined thicknesses, enabling them to simulate gaps of 10, 30, 90, and 120 thicknesses. This makes the demonstration scenarios richer and closer to the real working conditions of brake shoe wear in EMU braking systems. At the same time, the fixed connection between each padding body and the corresponding pneumatic telescopic rod body, the mutual contact between the surfaces of the superimposed padding bodies, and the contact between one side of the 10-thickness padding body and the first fixed frame effectively prevent the padding bodies from shifting or getting stuck, ensuring stable padding action and a smooth demonstration process. This helps operators to more intuitively understand the gap adjustment logic of the brake adjuster. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides an embodiment: a demonstration device for a high-speed train brake adjuster, including a platform 1, a limiting component and a padding component installed on the platform 1, an air source system 22 installed inside the platform 1, a controller 21 fixedly connected to the platform 1, a hydraulic telescopic rod body 23 fixedly connected to one end of the platform 1, a first connecting rod 24 with one end installed at the telescopic end of the hydraulic telescopic rod body 23, a brake adjuster body 25 with one end installed at the other end of the first connecting rod 24, and a second connecting rod 25 with one end installed at the other end of the brake adjuster body 25. Rod 27, first fixed frame 28 and second fixed frame 29 fixedly connected to the other end of the platform 1, sliding rod 211 slidably connected to the first fixed frame 28 and second fixed frame 29, abutment 212 threadedly connected to one end of sliding rod 211, spring 210 fixedly connected between the first fixed frame 28 and second fixed frame 29, pin 213 provided on the telescopic end of hydraulic telescopic rod body 23 and the first connecting rod 24, exhaust button 220 fixedly connected to the same side of platform 1 and controller 21, hydraulic telescopic rod button 221 The first stop button 222 and the second stop button 223 are fixedly connected to the limit block 26 on the platform 1. The other end of the sliding rod 211 is installed on the other end of the second connecting rod 27. The pin 213 is set on the gate regulator body 25, the second connecting rod 27 and the sliding rod 211. The second connecting rod 27 and the first connecting rod 24 are both set on the limit block 26. The air source system 22, the hydraulic telescopic rod body 23, the exhaust button 220, the hydraulic telescopic rod button 221, the first stop button 222, and the second stop button 223 are all... Electrically connected to the controller 21, the device can be connected to different models of gate regulator bodies 25 by replacing the second connecting rod 27 and the first connecting rod 24 with different lengths, and by using several sets of pins 213. This allows for quick adaptation to various gate regulator models. At the same time, by adjusting the limit requirements of the limit components according to the simulated model, the device can be restructured without disassembling or modifying the overall structure. This effectively improves the device's adaptability to different simulation scenarios, simplifies the operation process, reduces structural damage and error risks caused by frequent disassembly, and ensures the stability and convenience of the demonstration process.

[0024] Please see Figure 1A further solution based on this embodiment is as follows: both the second connecting rod 27 and the first connecting rod 24 are provided in two sets. One set of the second connecting rod 27 and the first connecting rod 24 is longer, and the other set is shorter. By providing two sets of second connecting rods 27 and the first connecting rod 24 with different lengths, the appropriate length of connecting rod can be selected directly according to the model of the gate regulator body 25 to be demonstrated, without the need to disassemble and modify the overall structure of the device, which greatly shortens the model switching time. At the same time, the fixed-specification length of connecting rods can avoid dimensional errors caused by temporary modifications, ensuring the connection accuracy of the first connecting rod 24, the second connecting rod 27 and the gate regulator body 25 after each switch, ensuring the accuracy of the demonstration data, and meeting the general demonstration needs of different models of gate regulators.

[0025] Please see Figure 4 A further solution based on this embodiment is as follows: The limiting component includes a support frame 214 fixedly connected to the inner wall of the platform 1, a mounting frame 215 bolted to the support frame 214, a first pneumatic telescopic rod body 216 and a second pneumatic telescopic rod body 218 fixedly connected to the mounting frame 215, a first stop body 217 fixedly connected to the telescopic end of the first pneumatic telescopic rod body 216, and a second stop body 219 fixedly connected to the telescopic end of the second pneumatic telescopic rod body 218. The air source system 22 is pneumatically connected to both the first pneumatic telescopic rod body 216 and the second pneumatic telescopic rod body 218. Both the first pneumatic telescopic rod body 216 and the second pneumatic telescopic rod body 218 are electrically connected to the controller 21. The first stop button 222 is used by the controller 21 to control the telescopic movement of the first pneumatic telescopic rod body 216, and the second stop button... Button 223 is used by controller 21 to control the extension and retraction of the second pneumatic telescopic rod body 218. By disassembling the limiting component into a combination structure of support frame 214, mounting frame 215, pneumatic telescopic rod body and stop body, and cooperating with the pneumatic drive of air source system 22 and the electrical control of controller 21, the operator can precisely control the extension and retraction of the stop body through the first / second stop button to achieve dynamic limiting of the gate regulator body 25. For example, when the limit range needs to be adjusted during the demonstration, there is no need to manually disassemble the stop; simply trigger the corresponding button for more convenient operation. At the same time, the design of mounting frame 215 being fixed to support frame 214 with bolts provides convenience for subsequent maintenance or replacement of the limiting component. If a pneumatic telescopic rod body malfunctions, mounting frame 215 can be disassembled separately for repair without disassembling the entire limiting component, reducing maintenance costs.

[0026] Please see Figure 4A further solution based on this embodiment is as follows: Two sets of first stop block bodies 217 and second stop block bodies 219 are provided. The two sets of first stop block bodies 217 and second stop block bodies 219 are symmetrically distributed on both sides of the gate regulator body 25. The platform 1 has through slots at corresponding positions of the first stop block bodies 217 and second stop block bodies 219. Both sets of first stop block bodies 217 and second stop block bodies 219 are located in the through slots of the platform 1. By symmetrically providing two sets of first / second stop block bodies on both sides of the gate regulator body 25, the gate regulator body can be adjusted from both sides. The body 25 forms a balanced limit, avoiding uneven force and tilting of the gate regulator body 25 caused by unilateral limit, ensuring that the gate regulator body 25 is always in the preset working posture during the demonstration, thus improving the realism of the demonstration; the opening of the through slot of the platform 1 provides sufficient space for the extension and retraction of the block body, avoiding collision and jamming between the block body and the housing of the platform 1 when it extends or retracts, reducing component wear, extending the service life of the block body and the pneumatic telescopic rod body, and also allowing the operator to intuitively observe the action status of the block body, making it easier to detect abnormalities in a timely manner.

[0027] Please see Figure 4 A further solution based on this embodiment is as follows: a long mounting groove is provided on the support frame 214, and the mounting frame 215 is installed on the long mounting groove on the support frame 214 by bolts. By providing a long mounting groove on the support frame 214, the mounting frame 215 can be adjusted and fixed along the length of the long mounting groove, thereby driving the first / second pneumatic telescopic rod body and the stop block body to move synchronously. It can adapt to the gate regulator body 25 of different sizes and different installation position requirements without replacing the entire limit assembly; the adaptability is stronger; at the same time, the bolt fixing method can ensure that the position of the mounting frame 215 is stable after adjustment and will not shift due to vibration during the demonstration, thus ensuring the limit accuracy.

[0028] Please see Figure 5A further embodiment of this solution is as follows: the padding assembly includes a base 31 fixedly connected to the platform 1, a sixth pneumatic telescopic rod body 38, a fifth pneumatic telescopic rod body 36, a fourth pneumatic telescopic rod body 34, and a third pneumatic telescopic rod body 32, all fixedly connected to the base 31 in sequence, a 120-thickness padding body 39 fixedly connected to the telescopic end of the sixth pneumatic telescopic rod body 38, a 60-thickness padding body 37 fixedly connected to the telescopic end of the fifth pneumatic telescopic rod body 36, a 20-thickness padding body 35 fixedly connected to the telescopic end of the fourth pneumatic telescopic rod body 34, a 10-thickness padding body 33 fixedly connected to the telescopic end of the third pneumatic telescopic rod body 32, and a padding body 33 fixedly connected to the platform 1 and the control... The thickness plus pad buttons 310 (10mm), 311 (20mm), 312 (60mm), and 313 (120mm) on the same side of the controller 21 are pneumatically connected to the sixth pneumatic telescopic rod body 38, the fifth pneumatic telescopic rod body 36, the fourth pneumatic telescopic rod body 34, and the third pneumatic telescopic rod body 32. The sixth pneumatic telescopic rod body 38, the fifth pneumatic telescopic rod body 36, the fourth pneumatic telescopic rod body 34, and the third pneumatic telescopic rod body 32 are electrically connected to the controller 21. The thickness plus pad buttons 310 (10mm), 311 (20mm), 312 (60mm), and 313 (120mm) are also electrically connected to the controller 21. On the controller 21, the thickness plus button 310 is used to control the extension and retraction of the third pneumatic telescopic rod body 32 via the controller 21; the thickness plus button 311 is used to control the extension and retraction of the fourth pneumatic telescopic rod body 34 via the controller 21; the thickness plus button 312 is used to control the extension and retraction of the fifth pneumatic telescopic rod body 36 via the controller 21; and the thickness plus button 313 is used to control the extension and retraction of the sixth pneumatic telescopic rod body 38 via the controller 21. By designing the plus assembly to include plus bodies of different thicknesses and corresponding pneumatic telescopic rod bodies, and in conjunction with the drive of the air source system 22 and the control of the independent plus buttons, the operator can accurately trigger the addition of single or combined thicknesses. The pad body extends to simulate different clearance changes caused by brake shoe wear in the EMU braking system. For example, it is necessary to simulate triggering the thickness 10 pad button 310 when there is slight wear, and triggering the thickness 120 pad button 313 when there is heavy wear. This facilitates demonstrations of 10, 30, 90, and 120 pads, making the demonstration scenarios richer and closer to real working conditions. At the same time, the fixed connection between each pad body and the corresponding pneumatic telescopic rod body ensures stable padding action, and the surfaces of the pads are in contact with each other. One side of the thickness 10 pad body 33 is in contact with the first fixed frame 28, so that the pad body will not shift or get stuck, ensuring the smoothness of the demonstration process and helping operators to more intuitively understand the clearance adjustment logic of the brake adjuster.

[0029] Please see Figure 5A further solution based on this embodiment is as follows: The test stand 1 has through slots corresponding to the thicknesses of the padding bodies 33 (10mm), 35 (20mm), 37 (60mm), and 39 (120mm). These through slots are positioned at the through slots on the test stand 1. By creating through slots at the corresponding positions of each padding body on the test stand 1, unobstructed space is provided for the extension and retraction of the padding bodies, preventing friction between the padding bodies and the test stand 1 shell when they extend, thus preventing wear or deformation of the padding body surface, ensuring the accuracy of the padding thickness, and consequently guaranteeing the accuracy of the gap simulation. Simultaneously, the through slots allow operators to clearly observe the extension length and status of the padding bodies, facilitating timely confirmation of whether the padding is in place, avoiding demonstration errors caused by incomplete extension of the padding bodies, and improving the controllability of the demonstration process.

[0030] Please see Figure 5 A further solution based on this embodiment is as follows: the 10-thickness pad body 33, the 20-thickness pad body 35, the 60-thickness pad body 37, and the 120-thickness pad body 39 are all designed in a U-shape to facilitate the normal sliding of the sliding rod 211 when it abuts against the abutment plate 212. By designing each pad body as a U-shaped structure, when the pad body extends out and abuts against the abutment plate 212 to simulate gap changes, the opening of the U-shape can reserve sufficient space for the sliding rod 211 to avoid collision or jamming between the pad body and the sliding rod 211, ensuring that the sliding rod 211 can slide smoothly on the first fixed frame 28 and the second fixed frame 29. The normal sliding of the sliding rod 211 is the key to the length adjustment demonstration of the gate adjuster body 25. Therefore, the design of the U-shaped pad body directly ensures the accuracy of the gate adjuster working principle demonstration, avoids demonstration interruption or logical deviation due to component interference, and improves the demonstration reliability of the device.

[0031] Working principle: Before the demonstration, according to the model of the gate regulator body 25 to be demonstrated (e.g., the ST2-250 model uses the long first connecting rod 24 and the second connecting rod 27, and the ST1-600 model uses the short first connecting rod 24 and the second connecting rod 27), the first connecting rod 24, the gate regulator body 25, and the second connecting rod 27 are connected in sequence through the pin 213. The other end of the second connecting rod 27 is connected to the sliding rod 211, and the first connecting rod 24 and the second connecting rod 27 are both placed on the limit block 26. At the same time, the position of the mounting frame 215 is adjusted along the long mounting groove of the support frame 214 so that the first pneumatic telescopic rod body 216 and the second pneumatic telescopic rod body 218 of the limit component correspond to the two sides of the gate regulator body 25. Then, the external main air source is turned on, and the air source system 22 provides power to each pneumatic component. The controller 21 is electrically connected to and coordinates the work of the air source system 22, the hydraulic telescopic rod body 23, and other components. During the demonstration, the controller 21 first controls the corresponding first pneumatic telescopic rod body 216 or second pneumatic telescopic rod body 218 via the first stop button 222 or the second stop button 223, allowing the first stop body 217 or the second stop body 219 to extend from the through slot of the test bench 1, forming a symmetrical limit on the brake adjuster body 25. When testing the ST1-600 brake adjuster, the two first stop bodies 217 are stored flush with the test bench 1. Then, according to the requirements of simulating brake shoe wear, the thickness 10 shim button 310, thickness 20 shim button 311, thickness 60 shim button 312, or thickness 120 shim button 313 are pressed. The controller 21 then controls the third pneumatic telescopic rod body 32, the fourth pneumatic telescopic rod body 34, the fifth pneumatic telescopic rod body 36, or the sixth pneumatic telescopic rod body 37. 8. Push the U-shaped pad body 33 (thickness 10), 35 (thickness 20), 37 (thickness 60), or 39 (thickness 120) out of the through slot of the stand 1 and abut against the abutment plate 212 to simulate different degrees of gap change; then press the hydraulic telescopic rod button 221, the hydraulic telescopic rod body 23 extends and retracts and pulls the brake adjuster body 25 through the first connecting rod 24, the brake adjuster body 25 drives the second connecting rod 27 and the sliding rod 211 to slide on the first fixed frame 28 and the second fixed frame 29, the spring 210 between the first fixed frame 28 and the second fixed frame 29 deforms accordingly to simulate the elastic deformation of the braking system, thus intuitively showing the adjustment action of the brake adjuster; after the demonstration, press the exhaust button 220 to exhaust the residual air pressure inside the device, completing the entire demonstration process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
