Description

Technical Field

[0001] The utility model relates to the technical field of pantographs, and in particular to a pantograph simulation device. Background Art

[0002] In high-speed rail systems, the proper functioning of overhead wires is crucial for safe operation. When it comes to catenary wire splits, the proper spacing (width) between two adjacent conductors directly impacts contact between the catenary wire and the pantograph during track changes. If the width is too large, the catenary wire will not be able to make smooth contact with the pantograph during track changes, potentially leading to serious accidents and posing a significant threat to passenger safety and national property. Therefore, a device that can quickly and accurately measure the spacing between adjacent conductors at catenary wire splits is urgently needed to ensure safe and reliable high-speed rail operation.

[0047] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0048] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0049] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0050] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0051] Reference Figures 1 to 4 , which is the first embodiment of the utility model, proposes a pantograph simulation device for detecting the distance between two adjacent conductors at a branch of a contact network conductor, including a support frame 1 with a standing space inside; one end of a first rotating rod 2 is rotatably set on the top of the support frame 1; an abutment 3 is set at the other end of the first rotating rod 2, and the abutment 3 has a first scale 31. After the first rotating rod 2 rotates, one side of the abutment 3 abuts against the two conductors.

[0052] In this embodiment, a standing space is provided within the support frame 1 to facilitate operation and observation. A first rotating rod 2 is pivotally connected at one end to the top of the support frame 1 to accommodate conductors at varying heights. An abutment 3 is provided at the other end of the first rotating rod 2 and is engraved with a scale. During testing, the operator rotates the first rotating rod 2 to ensure that the abutment 3 is in close contact with the two conductors at the branch. The scale then reads the spacing between the two conductors to ensure that it meets the required spacing.

[0053] The advantages include providing a specialized tool for measuring contact line conductor spacing. The standing space design facilitates operation and observation, improving detection efficiency and accuracy. The rotation of the first rotating rod 2 allows the abutment member 3 to flexibly adjust its angle and position, adapting to different conductors and enhancing versatility. The scale intuitively displays spacing, reducing measurement errors and improving accuracy.

[0054] Furthermore, it also includes a rotating insulating rod 4, which is rotatably arranged on the support frame 1, and the end of the first rotating rod 2 away from the abutment member 3 is rotatably arranged on the support frame 1 through the rotating insulating rod 4.

[0055] In this embodiment, the rotating insulating rod 4 is made of a material with excellent insulation properties, such as high-strength insulating engineering plastic, to prevent accidental electric shock to testers during testing. The rotating insulating rod 4 connects the support frame 1 and the first rotating rod 2, allowing the first rotating rod 2 to rotate and adjust in two dimensions. During operation, the rotating insulating rod 4 is rotated to achieve a wide range of angle adjustment, and the first rotating rod 2 is then fine-tuned to ensure that the abutment member 3 accurately abuts the wire.

[0056] The advantage is that, due to the insulating material properties of the rotating insulating rod 4, it can effectively block the induced current that may be generated between two adjacent contact wires, greatly improving the safety of the detection operation. At the same time, it increases the adjustability and flexibility of the device, making it easy to handle various complex contact wire layouts. By setting the rotating insulating rod 4, the operator can adjust the position of the abutment 3 within a wider range, significantly improving the applicability and ease of operation of the device. This multi-dimensional rotation adjustment method can effectively reduce measurement errors caused by inappropriate angles and provide a strong guarantee for accurately measuring the distance between wires.

[0057] Furthermore, the abutment 3 is rotatably arranged at one end of the first rotating rod 2, and the abutment 3 includes a rotating frame 32, which is rotatably arranged at one end of the first rotating rod 2; a first abutment plate 33 is arranged at one end of the rotating frame 32, and both ends of the first abutment plate 33 have a first bow angle 331, and the first scale 31 is located on the first abutment plate 33; a second abutment plate 34 is arranged at the other end of the rotating frame 32, and both ends of the second abutment plate 34 have a second bow angle 341, and the second abutment plate 34 also has a second scale 342.

[0058] In this embodiment, the rotating frame 32 of the abutment member 3 is connected to the first rotating rod 2 via a reliable rotational connection. This allows the rotating frame 32 to rotate freely on the first rotating rod 2, providing great measurement flexibility. A first abutment plate 33 and a second abutment plate 34 are securely mounted at each end of the rotating frame 32. The first scale 31 is finely engraved on the surface of the first abutment plate 33, making it easy to read. The first abutment plate 33 is designed with unique first angles 331 at each end. The second abutment plate 34 also features second angles 341 at each end. The first and second angles 331 and 341 differ in shape, differing in that the angle formed between the first angle 331 and the first abutment rod is smaller than the angle formed between the second angle 341 and the second abutment rod. The first abutment plate 33 with the first angle 331 simulates a low-speed pantograph, while the second abutment plate 34 with the second angle 341 simulates a high-speed pantograph, ensuring measurement accuracy. The second abutment rod also features a second scale 342. In actual use, the operator can flexibly rotate the rotating frame 32 according to different measurement requirements and select the first abutment plate 33 or the second abutment plate 34 to align with the wire for measurement.

[0059] The advantage is that the rotating design of the abutment member 3 allows for greater flexibility and variety in measurement methods. The different scales on the first and second abutment plates 33, 34 provide multiple options for measurements with varying precision requirements, greatly improving the device's applicability. The bow angle design allows for a close fit with the conductor, effectively ensuring measurement accuracy. The structure of the rotating frame 32 facilitates rapid switching between the first and second abutment plates 33, 34 in different measurement situations, significantly improving work efficiency.

[0060] Furthermore, the second abutment plate 34 includes a mounting plate 343, which is arranged at one end of the rotating frame 32 away from the first abutment plate 33, and the second scale 342 is located on the mounting plate 343; there are two sliding plates 344, and the two sliding plates 344 are both slidably set on the mounting plate 343, with opposite sliding directions, and the second bow angles 341 are respectively located at one end of the two sliding plates 344. After the two sliding plates 344 slide, the distance between the two second bow angles 341 is expanded or reduced.

[0061] In this embodiment, the mounting plate 343 of the second abutment plate 34 is mounted on the rotating frame 32, and two sliding plates 344 are slidably mounted on both sides of the mounting plate 343. The sliding plates 344 can be manually pushed to adjust the bow angle spacing to accommodate different wire spacings, and the spacing can be read using a scale.

[0062] The advantages include adapting to different situations and measuring conductors with different spacing, improving versatility. Sliding to adjust the spacing allows for more accurate measurements, improving precision and reliability. It's also easy to operate and reduces the hassle of changing tools.

[0063] Furthermore, it also includes a first air spring 5, the two ends of the first air spring 5 are respectively in contact with the support frame 1 and the rotating insulating rod 4, and are used to support the relative position between the support frame 1 and the rotating insulating rod 4; the two ends of the second air spring 6 are respectively in contact with the rotating insulating rod 4 and the first rotating rod 2, and are used to support the relative position between the first rotating rod 2 and the rotating insulating rod 4.

[0064] In this embodiment, the first air spring 5 connects the support frame 1 and the rotating insulating rod 4, and the second air spring 6 connects the rotating insulating rod 4 and the first rotating rod 2. The air spring automatically adjusts the support force according to the position change of the rotating rod, buffering external forces and ensuring measurement accuracy.

[0065] The benefits include providing stable support for the rotating rod, ensuring device stability and reliability, absorbing vibration and impact, and reducing external influences. It also automatically adjusts to different environments and operating requirements, improving versatility and practicality.

[0066] Furthermore, it also includes a hand-turned wheel 7, which is rotatably arranged in the standing space, with one end extending out of the standing space; a first transmission wheel 8 is arranged at one end of the hand-turned wheel 7, coinciding with the axis of the hand-turned wheel 7, and the hand-turned wheel 7 drives the first transmission wheel 8 to rotate; a second transmission wheel 9 is arranged at one end of the rotating insulating rod 4, and the rotating insulating rod 4 is rotatably arranged on the support frame 1 through the second transmission wheel 9, and the second transmission wheel 9 is connected to the first transmission wheel 8 for transmission. After the second transmission wheel 9 rotates, it drives the rotating insulating rod 4 to rotate.

[0067] In this embodiment, a handwheel 7 is mounted in the standing space of the support frame 1. A first transmission wheel 8 is coaxial with the handwheel 7. Turning the handwheel 7 rotates the first transmission wheel 8. A second transmission wheel 9 is located at one end of the rotating insulating rod 4 and is chain-connected to the first transmission wheel 8. Turning the handwheel 7 rotates the rotating insulating rod 4 to adjust its position.

[0068] The advantages include convenient manual adjustment of the four rotating insulating rod angles, improving operational convenience and precision. The reliable chain drive ensures stable rotation. Manual adjustment eliminates the need for an additional power source, reducing cost and complexity while improving applicability.

[0069] Furthermore, it also includes a third transmission wheel 10, which is arranged on the first transmission wheel 8, coincides with the axis of the first transmission wheel 8 and rotates synchronously; a fourth transmission wheel 11 is rotatably arranged on the support frame 1, and the fourth transmission wheel 11 is transmission-connected to the third transmission wheel 10; a fifth transmission wheel 12 is arranged on the third transmission wheel 10, coincides with the axis of the third transmission wheel 10 and rotates synchronously; a sixth transmission wheel 13 is rotatably arranged on the support frame 1, and the sixth transmission wheel 13 is meshed with the fifth transmission wheel 12; a seventh transmission wheel 14 is arranged on the sixth transmission wheel 13, coincides with the axis of the fifth transmission wheel 12 and rotates synchronously; an eighth transmission wheel 15 is arranged at one end of the first rotating rod 2, and the first rotating rod 2 is rotatably arranged on the rotating insulating rod 4 through the eighth transmission wheel 15, and the eighth transmission wheel 15 is transmission-connected to the seventh transmission wheel 14. After the eighth transmission wheel 15 rotates, it drives the first rotating rod 2 to rotate.

[0070] In this embodiment, multiple transmission wheels cooperate to form an efficient transmission system. The third transmission wheel 10 is tightly mounted on the first transmission wheel 8, aligning its axis with the first transmission wheel 8 and enabling synchronous rotation. The fourth transmission wheel 11 is mounted on the support frame 1 and connected to the third transmission wheel 10 via a chain. The fifth transmission wheel 12 is also mounted on the third transmission wheel 10, aligning its axis with the third transmission wheel 10 and enabling synchronous rotation. The sixth transmission wheel 13 is rotatably mounted on the support frame 1 and meshing with the fifth transmission wheel 12. The seventh transmission wheel 14 is mounted on the sixth transmission wheel 13, and the eighth transmission wheel 15 is mounted at one end of the first rotating rod 2. The eighth transmission wheel 15 is connected to the seventh transmission wheel 14 via a chain transmission. When the operator turns the hand wheel 7, power is transmitted through each transmission wheel in sequence, ultimately driving the eighth transmission wheel 15 to rotate, thereby rotating the first rotating rod 2. In this process, the size and number of teeth of each transmission wheel are carefully designed to ensure accurate and stable transmission.

[0071] The advantage is that the provision of multiple transmission wheels enables the hand wheel 7 to simultaneously control the first rotating rod 2 and the rotating insulating rod 4, greatly improving the convenience and efficiency of operation. The combination of chain drive and gear meshing transmission ensures transmission accuracy and stability. The addition of meshing transmission also enables the first rotating rod 2 and the rotating insulating rod 4 to rotate in opposite directions, allowing the first abutting rod and the second abutting rod to rotate in the direction of folding and retracting.

[0072] Furthermore, it also includes a tensioning slider 16, which is slidably set on the support frame 1; a tensioning wheel 17 is rotatably set on the tensioning slider 16, and the tensioning wheel 17 is transmission-connected to the eighth transmission wheel 15 and the seventh transmission wheel 14; the two ends of the elastic member 18 are respectively in contact with the tensioning slider 16 and the support frame 1, for providing a force to move the tensioning slider 16 away from the seventh transmission wheel 14.

[0073] In this embodiment, the tensioning slider 16 is mounted on the support frame 1 via a precise sliding connection, allowing it to slide smoothly on the support frame 1. The tensioning pulley 17 is mounted on the tensioning slider 16 via a reliable rotational connection and is connected to the eighth transmission pulley 15 and the seventh transmission pulley 14 via a chain. The ends of the elastic member 18 abut the tensioning slider 16 and the support frame 1, respectively, providing a constant force to push the tensioning slider 16 away from the seventh transmission pulley 14. During operation, the elastic member 18 ensures that the tensioning pulley 17 maintains tension on the chain.

[0074] The advantage is that the combination of tensioning slider 16, tensioning wheel 17, and elastic member 18 ensures that the transmission chain is always in a tensioned state, effectively preventing transmission instability and errors caused by chain slack. This automatic tensioning design improves the reliability and stability of the device, reducing maintenance costs and workload. It also ensures transmission accuracy, allowing precise control of the rotation of the first rotating rod 2 and the rotating insulating rod 4, further improving measurement precision.

[0075] Furthermore, a grounding wire 19 is included, and two ends of the grounding wire 19 are respectively in contact with the first rotating rod 2 and the supporting frame 1.

[0076] In this embodiment, the grounding wire 19 connects the first rotating rod 2 and the supporting frame 1 to conduct static electricity into the ground, thereby ensuring safety and normal operation of the device.

[0077] The benefits are that it improves device safety, prevents electrostatic hazards, ensures safe and reliable measurements, and reduces electrostatic interference errors.

[0078] The first scale 31 on the abutment 3, when in contact with the conductor and adjusted in position, allows for accurate measurement of the catenary conductor's pullout—the distance the conductor is offset perpendicular to the track—using a specific measuring sensor. This is crucial for ensuring proper lateral contact between the conductor and the pantograph, helping to determine whether the conductor layout meets safety and operational requirements.

[0079] A laser distance measuring device can also be installed on the rotating insulating rod 4. When the abutment 3 contacts the conductor, it can measure the conductor height of the catenary wire, that is, the height of the conductor above the track plane. Accurate conductor height measurement helps ensure uniform contact pressure between the abutment 3 and the conductor. Simultaneously, the laser distance measuring device can slide laterally on the rotating insulating rod 4, synchronizing with the curve of the catenary wire. This allows for the measurement of the conductor height at any given moment, ensuring the stability and safety of power transmission.

[0080] The device can also include built-in sensing elements and an alarm system. When disconnection is detected between the abutment member 3 and the contact wire, i.e., a momentary loss of contact between the two, an alarm signal can be promptly issued. For example, the disconnection state can be determined by detecting changes in current or voltage. Once disconnection occurs, the alarm system will alert the operator through sound, light, or other means, allowing timely maintenance and adjustment measures to avoid power transmission interruption or other safety issues caused by disconnection.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
