Description

Technical Field

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

[0002] With the rapid development of high-speed railway technology, as a key component for trains to obtain electric energy, the stability and efficiency of the pantograph's performance are directly related to the safe operation of the train. Traditional pantograph teaching mainly relies on physical operation, which has problems such as high cost, high risk, and difficult maintenance. Therefore, developing a simulation pantograph teaching model has become an effective way to solve these problems.

[0003] The simulation pantograph teaching model also has a fault simulation function, which can simulate various pantograph-catenary fault scenarios to help students master fault troubleshooting and emergency handling skills. At the same time, the model also supports the simulation and verification of various control algorithms, such as active control, semi-active control, etc., providing strong support for the research of pantograph control strategies.

[0004] For example, the Chinese utility model patent (CN214253641 U) discloses a single-arm pantograph model for teaching, which solves the following problems: the insulator structure in the traditional single-arm pantograph is relatively simple, without a pneumatic decontamination component, and the surface of the insulator is prone to be contaminated with oil stains and cannot be automatically removed, resulting in the risk that the insulator with dirt is prone to partial discharge, and seriously, it may cause the line to trip and power off.

[0005] The device includes a chassis, a first fixing block, a first mounting shaft, a lower arm rod, a second mounting shaft, an upper frame, a second fixing block, a side arm, a lower guide rod, a transmission cylinder, a carbon slide plate, a fixing seat, an insulator, a pneumatic decontamination component, an arcing plate, a limiting plate, and a strengthening pull rod. The first fixing blocks are symmetrically installed on the outer wall of the middle part of the top of the chassis. The first mounting shaft is rotatably installed on the outer wall between the first fixing blocks. The lower arm rod is welded and fixed on the outer wall of the middle part of one side of the first mounting shaft. The second mounting shaft is welded and fixed on the outer wall of one end of the lower arm rod; this new type is restored one-to-one according to the single-arm pantograph on the electric locomotive, which is beneficial to the training and learning of the pantograph locomotive. A pneumatic decontamination component is arranged on the insulator of the pantograph, which can automatically clean the oil stains on the surface of the insulator through a brush; the setting of the arcing plate on the insulator improves the lightning protection effect of the insulator.

[0006] When using the above-mentioned technology, the following technical problems are found in the existing technology: The device lacks a suitable clamping structure, resulting in the inability to tightly connect the conductive copper bar inside the device. The copper bar not only undertakes the task of transmitting electric energy but also bears various forces and vibrations during the train operation. The lack of a clamping structure will prevent students from intuitively understanding the function and influence of this key component, thus affecting the teaching effect and students' comprehensive mastery of pantograph knowledge. Therefore, we design a simulation pantograph teaching model to provide another technical solution to the above technical problems. Summary of the Invention

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present utility model clearer, 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 the present utility model and are not used to limit the present utility model.

[0032] As described in the background art, the device lacks a suitable clamping structure, resulting in the conductive copper bar not being tightly connected inside the device. The copper bar not only undertakes the task of transmitting electric energy but also bears various forces and vibrations during the train operation. The lack of a clamping structure makes it impossible for students to intuitively understand the role and influence of this key component, thus affecting the teaching effect and students' comprehensive mastery of pantograph knowledge.

[0033] To solve this technical problem, the utility model provides a simulation pantograph teaching model.

[0042] The clamping structure includes a rotating mechanism and a locking mechanism. One side of the top of the bow head 15 is fixed with the rotating mechanism, and the locking mechanism is arranged on one side of the rotating mechanism, enabling the clamping structure to clamp a copper bar.

[0043] The rotating mechanism includes a connecting block 16, a rotating shaft 21, and a cam 22. One side of the top of the bow head 15 is fixed with the connecting block 16. The inner side of the connecting block 16 is rotatably connected to the rotating shaft 21, and the cam 22 is fixed on the outer side of the rotating shaft 21, enabling the rotating mechanism to drive the cam 22 to rotate.

[0044] The locking mechanism includes a fixed block 17, a handle 18, a worm 19, and a worm gear 20. Both ends of the top of the connecting block 16 are fixed with the fixed block 17. One side of one of the fixed blocks 17 is rotatably connected to the handle 18. The worm 19 is rotatably connected to the side of the two fixed blocks 17 close to each other. The handle 18 is fixed to the worm 19. One end of the outer side of the rotating shaft 21 is fixed with the worm gear 20. The worm 19 is meshed and connected to the worm gear 20, enabling the locking mechanism to restrict the rotation of the rotating shaft 21.

[0045] Two rectangular grooves are opened at the top of the worm 19, and a copper bar is arranged inside the rectangular grooves, enabling the trainee to visually observe the transmission process of the current between the bow head and the catenary, thereby deepening the understanding of the working principle of the pantograph.

[0046] The pneumatic cylinder 5 is electrically connected to the electric control box 9, enabling the electric control box 9 to control the pneumatic cylinder 5.

[0047] The bow head 15 can work within a certain height range to adapt to the change of the catenary height under different line conditions. This characteristic is reflected in the simulation teaching model, which helps the trainee understand the working ability of the pantograph under different line conditions.

[0048] Most parts of this device are made by 3D printing. Furthermore, the parts can be directly printed according to the precise CAD model, ensuring that the part sizes, shapes, and proportions of the simulation pantograph teaching model are consistent with the real pantograph height, and improving the authenticity of the model.

[0049] One side of the pneumatic cylinder 5 is connected with an air compressor, which is used to provide power for the pneumatic cylinder.

[0050] A simulation pantograph teaching model provided by the utility model. Through the design of the lifting structure, the device is closer to the working state of the real pantograph, thus improving the authenticity and credibility of the model. When students use the model for learning, they can better combine the knowledge they have learned with practical applications.

[0051] Through the design of the clamping structure, the device can tightly clamp the copper rod. Compared with the model lacking an efficient clamping structure, the model with this structure can reduce the errors caused by unstable contact during the simulation process, thus providing more accurate data and results, and providing a reliable basis for students' learning and research.

[0052] The using process of a simulation pantograph teaching model provided by the utility model is as follows: The user puts two copper rods into the grooves at the top of the pantograph head 15, and then rotates the handle 18. The rotation of the handle 18 drives the worm 19 to rotate. Since the bottom of the worm 19 is meshed and connected with the worm gear 20, the rotation of the worm 19 drives the worm gear 20 to rotate. The rotation of the worm gear 20 drives the rotating shaft 21 and the cam 22 to rotate, so that the cam 22 can tightly clamp the copper rod. The user electrically connects the two copper rods, and then controls the electric control box 9 to operate the pneumatic cylinder 5. The user energizes and inflates the pneumatic cylinder 5, so that the output end of the pneumatic cylinder 5 drives the support rod 8 to extend, thereby driving the concave block 6 to rotate and lift. The lifting of the concave block 6 drives the upper arm rod 14 to rotate and lift. Since one end of the upper arm rod 14 is rotatably connected with the pull rod 11, and one end of the bottom of the upper arm rod 14 is rotatably connected with the lower arm rod 12, the upper arm rod 14 can drive the pantograph head 15 to lift. Since one side of the bottom of the pantograph head 15 is connected with the lower arm rod 12 through the balance rod 13, the pantograph head 15 can move vertically. The vertical up and down movement of the pantograph head 15 is the key to automatically adjusting the pantograph-catenary contact pressure. When the height of the catenary changes, the pantograph head 15 can quickly respond and adjust its height to keep the pantograph-catenary contact pressure basically constant. To sum up, the utility model can improve the authenticity and accuracy of the model, enhance the teaching demonstration effect, facilitate the teaching of fault simulation and diagnosis, and promote students' understanding of the structural principle of the pantograph. These benefits make the model have higher application value in the field of pantograph teaching, and have broad application prospects and popularization value.
