Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology for electric locomotives, and in particular to a foldable, low-drag, high-speed train pantograph. Background Technology

[0002] A foldable, low-drag high-speed train pantograph is a key piece of equipment meticulously developed to meet the demands of high-speed trains for efficient current collection and low wind resistance during high-speed operation. It aims to improve train stability, reduce energy consumption, and facilitate maintenance and storage. This foldable, low-drag high-speed train pantograph is widely used in various types of high-speed trains, significantly improving current collection quality and operating efficiency, reducing energy consumption and maintenance costs, and providing strong support for the safe and efficient operation of high-speed trains. It is of great significance for promoting the development of the railway transportation industry towards higher speeds and greater energy efficiency and environmental protection.

[0003] Integrating aerodynamics, intelligent folding, and efficient power supply technologies, this pantograph provides a reliable guarantee for stable power intake for trains. Featuring a streamlined, low-drag structure, intelligent electric folding, an adaptive contact force control module, lightweight and high-strength materials, and a modular maintenance design, this pantograph is equipped with a fault warning function that can transmit operational status data to the ground monitoring center in real time. Compared with traditional pantographs, it improves power supply reliability and is widely applicable to high-speed trains with speeds exceeding 100 km / h. It is particularly significant for reducing train operating energy consumption and ensuring high-speed power supply safety.

[0004] When a train is traveling at high speed and requires stable current collection, the pantograph cannot extend sufficiently, resulting in insufficient contact length with the overhead contact line. This can lead to unstable current collection and affect power transmission efficiency. Conversely, when the train is running at low speed or entering a station, the pantograph maintains a large contact length, increasing air resistance, applying unnecessary pressure to the overhead contact line, aggravating wear between the pantograph and the contact line, and shortening the service life of both. Consequently, the pantograph may not be able to simultaneously meet the dual requirements of current collection stability and energy saving under different operating scenarios. Therefore, a foldable, low-wind-resistance high-speed train pantograph is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a foldable, low-wind-resistance high-speed train pantograph, which aims to improve the problem that the pantograph head length cannot be changed according to the train speed in the prior art.

Two racks are fixedly connected to the inner wall of the housing. Two limiting frames are fixedly connected to the inner wall of the housing. A sliding groove is formed on the inner wall of the limiting frame. A motor is slidably connected to the rear side of the limiting frame.

Two first protective shells are fixedly connected to the inner wall of the second outer shell. A second protective shell is slidably connected to the inner wall of the first protective shell. A spring is fixedly connected to the inner wall of the second protective shell.

[0010] As a further description of the above technical solution:

[0011] The two sliding plates are slidably connected to the inner wall of the outer casing, and the bottom end of the sliding plate is fixedly connected to the top end of the motor.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rotating shaft is slidably connected to the inner wall of the slide groove, and the outer teeth of the gear and the outer teeth of the rack are meshed with each other.

[0014] As a further description of the above technical solution:

[0015] A rack two is fixedly connected to the left side of the support rod. The outer teeth of the gear two and the outer teeth of the rack two are meshed with each other. The bottom end of the protective shell one is fixedly connected to the top end of the support rod.

[0016] As a further description of the above technical solution:

[0023] 1. In this utility model, the motor serves as the power source structure. After starting, it drives the rotating shaft and gear to rotate, thus operating the transmission structure. When gear and rack drive each other, the sliding plate moves, which in turn causes the support block to move horizontally via the rotating arm. The support column fixed on the right side of the support block provides support for the rotating wheel, ensuring the stable operation of the pantograph. This allows the telescopic pantograph head to be extended and retracted according to the train speed and the conditions of the overhead contact line, reducing wind resistance, improving the reliability and service life of the pantograph, and providing stable power reception and safe operation for high-speed trains.

[0024] 2. In this utility model, the second motor drives the second gear to rotate, which in turn moves the sliding column, allowing the nozzle on the left side of the sliding column to reach different positions on the pantograph head for cleaning. This achieves all-round cleaning of the pantograph head. The limiting ring, as a limiting structure, precisely limits the movement range of the sliding column, thereby achieving efficient and stable cleaning of the pantograph head, removing dirt and impurities, reducing wear, improving the conductivity and service life of the pantograph, and ensuring stable power supply for high-speed trains.

[0043] Working principle: When motor 6 drives gear 8 to rotate clockwise, gear 8 drives sliding plate 10 to move to the right along the track of rack 3. Rotating shaft 7 slides to the right on the inner wall of slide groove 5. Sliding plate 10 drives rotating arm 11 to move to the right. Rotating arm 11 drives support block 12 and bow head 28 to move to the right. Rotating wheel 14 contacts the inclined surface of triangle plate 15. Rotating wheel 14 drives support block 12 to move upward through support column 13. At the same time, rotating arm 11 rotates counterclockwise. Due to the influence of sliding plate 10 and rotating wheel 14, bow head 28 moves to the upper right. When bow head 28 moves to be parallel with bow head 29, the extension operation of bow head 28 is completed.

[0044] When motor 6 drives gear 8 to rotate counterclockwise, gear 8 moves sliding plate 10 to the left along the track of rack 3. Rotating shaft 7 slides to the left on the inner wall of slide groove 5. Sliding plate 10 moves rotating arm 11 to the left. Rotating arm 11 moves support block 12 and bow head 28 to the left. Rotating wheel 14 moves along the inclined surface of triangle plate 15. Rotating wheel 14 moves support block 12 downward through support column 13. At the same time, rotating arm 11 rotates clockwise. Due to the influence of sliding plate 10 and rotating wheel 14, bow head 28 moves to the lower left. When bow head 28 is completely moved into the inside of outer shell 2, the bow head 28 storage operation is completed.

[0045] When motor 219 drives gear 20 to rotate counterclockwise, another spring 27 releases its elastic force to provide forward assistance to motor 219. Gear 20 moves horizontally forward along the outer teeth of rack 230. Gear 20 drives nozzle 22 to slide forward along the inner wall of slide groove 24. When the front of motor 219 contacts protective shell 26, it drives protective shell 26 to move forward. Spring 27 is compressed and provides cushioning for motor 219. At this time, the cleaning operation on the front side is completed.

[0046] When motor 219 drives gear 20 to rotate clockwise, spring 27 releases its elastic force to provide rearward assistance to motor 219. Gear 20 moves horizontally to the rear along the outer teeth of rack 230. Gear 20 drives nozzle 22 to slide to the rear along the inner wall of slide groove 24. When the rear of motor 219 contacts another protective shell 26, it drives the other protective shell 26 to move to the rear. Another spring 27 is compressed and provides cushioning for motor 219.
