Description

Technical Field

[0001] This utility model relates to the technical field of pantograph carbon sliding plates, and in particular to a pantograph carbon sliding plate with interchangeable thickness for practical training. Background Technology

[0002] In electric locomotive power supply systems, the pantograph carbon contact plate, as a key component connecting the overhead contact line and the pantograph, plays a crucial role in conductivity, pressure bearing, and wear absorption. As train operation time increases, the carbon contact plate gradually thins, necessitating periodic measurement and replacement. To improve the practical skills of electric locomotive maintenance personnel, various vocational schools and training institutions typically include relevant training programs to teach the measurement, replacement, and judgment standards of the carbon contact plate.

[0003] Existing carbon slide plates in training equipment are typically fixed structures with a constant thickness, making it impossible to meet the training needs of changing slide plates or simulating different wear conditions. This single structure not only limits the diversity of training content, but also makes it difficult to objectively assess students' mastery of measurement skills since they can complete the operation by memorizing the fixed parameters of the carbon slide plate, thus affecting the authenticity and effectiveness of teaching.

[0004] Furthermore, most existing carbon skateboard samples are disassembled from actual equipment, which is not only costly but also limited in quantity, making it difficult to meet the needs of multiple students training simultaneously. In daily teaching, repeatedly using carbon skateboard samples of a fixed thickness can easily lead to equipment wear and error accumulation, affecting measurement accuracy and training quality.

[0005] In view of this, the inventors specifically designed a pantograph carbon slide plate with interchangeable thickness for practical training, which led to this invention. Utility Model Content

[0006] The purpose of this application is to provide a pantograph carbon slider with interchangeable thickness for practical training, which at least solves the problems of fixed thickness of existing pantograph carbon sliders for practical training, inability to be replaced and measured multiple times, and poor training effect for students.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a pantograph carbon strip with interchangeable thickness for practical training, comprising: a base for supporting the overall structure; a C-shaped steel disposed on the base for forming an installation area for placing a carbon strip simulator; and a rubber block for simulating pantograph carbon strips of different thicknesses, wherein the rubber block is detachably installed within the installation area formed by the C-shaped steel. A limiting structure, set on the base and / or the fixed C-shaped steel, is used to limit and position the rubber block to prevent it from sliding or shifting during installation; a thickness marking structure, set on the end face of the rubber block, is used to indicate the thickness information of the rubber block.

[0008] In a further embodiment, the two sides of the C-shaped steel are arranged perpendicular to the base and are fixedly connected to the base by bolts.

[0009] In a further embodiment, the limiting structure includes a limiting groove disposed inside the C-shaped steel, which matches the bottom or side of the rubber block to achieve snap-fit ​​limiting installation.

[0010] In a further embodiment, the inner surface of the limiting groove is provided with an elastic snap-fit ​​structure.

[0011] In a further embodiment, the thickness marking structure is a digital scale etched onto the front surface of the rubber block.

[0012] In a further embodiment, the surface of the rubber block is further provided with a QR code or NFC tag.

[0013] In a further embodiment, the base is equipped with a measuring auxiliary scale.

[0014] Compared with the prior art, the present invention has the following advantages: By setting C-shaped steel on the base to form an installation area, and in conjunction with detachable rubber blocks, limiting structures, and thickness marking structures, the thickness of the carbon slide plate can be flexibly changed and stably positioned. This not only avoids the drawback of students relying on memory to complete measurements due to fixed parameters, but also improves the intuitiveness and accuracy of measurements through thickness markings and measurement auxiliary rulers. This significantly enhances the diversity, authenticity, and assessment effect of practical training, reduces teaching costs, and improves the practicality and operability of the device.

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a pantograph carbon sliding plate with interchangeable thickness for practical training. Its overall structure mainly includes a base 1, a C-shaped steel 2, a rubber block 3, a limiting structure 4, and a thickness marking structure 5. This device aims to solve the problems of fixed carbon sliding plate thickness in existing practical training, which prevents flexible replacement and results in limited measurement effectiveness, thereby improving the realism and operability of teaching and training.

[0020] In one specific embodiment, the base 1 is a rectangular metal base used for overall load-bearing and support. The surface of the base 1 has several mounting holes to securely mount the C-shaped steel 2 onto the base 1 using bolts 6. The two sides of the C-shaped steel 2 are perpendicular to the base 1, forming a U-shaped clamping space, which serves as the mounting area for the rubber block 3. The C-shaped steel 2 and the base 1 are fixedly connected by bolts 6, ensuring the stability of the overall structure and facilitating future maintenance or replacement.

[0021] like Figure 1 As shown, rubber block 3, serving as a simulation component for the carbon slide plate, is made of wear-resistant rubber material, effectively reducing training costs and avoiding carbon powder contamination. Rubber block 3 is available in various thicknesses, such as 10mm, 12mm, and 15mm, allowing students to select different specifications for installation during training based on teaching needs. Rubber block 3 can be disassembled and installed within the installation area formed by C-shaped steel 2 via a plug-in method, replacing the traditional carbon slide plate and enabling quick replacement and reuse.

[0022] like Figure 3As shown, to prevent the rubber block 3 from loosening or shifting after installation, this utility model provides a limiting structure 4 on the base 1 and / or the C-shaped steel 2. In a preferred embodiment, the limiting structure 4 is a limiting groove inside the C-shaped steel 2, which matches the bottom or side of the rubber block 3, allowing the rubber block 3 to be snap-fitted and fixed during insertion, thus maintaining a stable position. Furthermore, an elastic buckle structure 21 can be provided on the inner surface of the limiting groove. During installation of the rubber block 3, the buckle undergoes slight elastic deformation and automatically resets after installation to form a locking effect, ensuring that the rubber block 3 will not loosen due to external force.

[0023] To help students accurately identify rubber blocks 3 of different thicknesses during practical training, this invention provides a thickness marking structure 5 on the end face of the rubber block 3. The thickness marking structure 5 can be a digital scale 51, formed by laser etching or mold imprinting, visually displaying the thickness value of the rubber block 3. As a further improvement, a QR code 52 or an NFC tag can be attached to the surface of the rubber block 3 for use with electronic identification equipment, enabling automated reading and recording of the rubber block 3's thickness information, facilitating teaching assessment and data management.

[0024] like Figure 2 As shown, in addition to improving the accuracy of student measurements and the practical training experience, a measurement auxiliary ruler 7 can also be set on the surface of the base 1. The measurement auxiliary ruler 7 can be a metal ruler or a printed scale line, which forms a reference with the end face of the rubber block 3. When measuring the thickness, students can quickly compare the actual thickness of the rubber block 3 with the marked thickness, improving the intuitiveness and repeatability of measurement training.

[0025] In another embodiment, the present invention may also be equipped with thickness adjustment shims. The adjustment shims are a stacked structure of several pieces, each 1mm or 2mm thick, installed between the rubber block 3 and the base 1, for fine-tuning the overall thickness of the rubber block 3. By stacking different numbers of shims, more thickness combinations can be obtained, further increasing the diversity and complexity of training. For easy identification, the surface of the adjustment shims can be marked with different colors or codes. During practical training, students not only need to measure the thickness of the carbon skateboard but also need to identify the thickness combinations of the adjustment shims, thereby enhancing their comprehensive assessment ability in practical training.

[0026] Through the above embodiments, this utility model achieves a modular and replaceable design for the carbon skateboard simulator, providing multiple thickness combinations for practical training and overcoming the shortcomings of existing technologies where the carbon skateboard thickness is fixed and the training content is limited. Simultaneously, the limiting structure 4 and the buckle design improve the stability and reliability of the rubber block 3 installation, while the thickness markings and auxiliary rulers enhance the accuracy and intuitiveness of measurements. The QR code 52 or NFC tag can be expanded to provide electronic management functionality. This device has a simple structure, low manufacturing cost, and can be widely applied in practical training scenarios such as vocational schools and locomotive maintenance training, showing promising prospects for widespread application.

[0027] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
