DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: a pantograph ice breaking device for an electric locomotive, comprising a support rod 10, a carbon slide frame 11 being fixedly connected to the top of the support rod 10, a connecting plate 12 being fixedly connected to the right side of the carbon slide frame 11, two fixed seats 29 being fixedly connected to the inner wall of the connecting plate 12, two rotating rods 31 being rotatably connected to the outer side of the fixed seat 29, a moving shaft 25 being fixedly connected to one side of the fixed seat 29, a fixed plate 23 being slidably connected to the outer side of the moving shaft 25, a vibration shell 26 being fixedly connected to one side of the fixed plate 23, a sliding rod 27 being fixedly connected to the inside of the vibration shell 26, two springs 22 being sleeved on the outer side of the sliding rod 27, two sliding blocks 28 being slidably connected to the outer side of the sliding block 27, a rotating rod 31 being arranged between the sliding block 28 and the fixed seat 29, and a vibration shell 26 being fixedly connected to the outer side of the vibration shell 26. A fixed shaft 24 is fixedly connected, a moving block 13 is fixedly connected to the outside of the vibration shell 26, two connecting rods 14 are slidably connected inside the moving block 13, a scraper shell 15 is fixedly connected to the top of the connecting rod 14, a scraper assembly is arranged inside the scraper shell 15, a fixed assembly is arranged on the outside of the moving block 13, a rotating shaft 6 is movably sleeved on the outside of the support rod 10, a lower arm rod 5 is fixedly connected to the lower right side of the rotating shaft 6, a base frame 1 is movably sleeved on the bottom of the lower arm rod 5, a connecting column 9 is fixedly connected to the bottom of the support rod 10, a pull rod 8 is rotatably connected to the bottom of the connecting column 9, two insulators 2 are fixedly connected to the bottom of the base frame 1, a lifting column 30 is movably connected to the upper surface of the base frame 1, a base frame current connection group 3 is fixedly connected to the right side of the upper surface of the base frame 1, and the bottom of the lower arm rod 5 is movably sleeved on the base frame 1.

[0033] Specifically, first, the staff ensures that the pantograph is in contact with the contact network, and the electric locomotive starts running. The high-speed moving pantograph removes ice accumulated on the contact network through the installed scraper assembly. When the direction of the EMU track changes, due to the action of the contact network cable, the scraper shell 15 and the moving block 13 will change angle, which will drive the connecting rod 14 and the moving block 13 to slide, and then through the operation of the sliding moving block 13 and the connecting plate 12, the spring 22 is compressed. At the same time, this process will also drive the fixed plate 23 to slide on the outside, protecting the contact network and the scraper 7 from damage by the ice layer, and causing the ice layer to fall off. The entire design cleverly uses mechanical movement to achieve the de-icing function. The design of the chassis and insulator 2 ensures the electrical safety of the entire device, and the lifting column 30 allows the height of the device to be adjusted as needed to adapt to different operating conditions. The structure of the lower arm 5 and the rotating shaft 6 allows the device to be adjusted accordingly according to the operating status of the locomotive, thereby improving the de-icing efficiency.

[0034] Reference Figure 5The fixed component includes a thin shell 16, the outer side of the thin shell 16 is fixedly connected to the outer side of the moving block 13, the top of the thin shell 16 is fixedly connected to a thin shell 2 17, the inside of the thin shell 16 is slidably connected to a plug rod 21, one side of the outer side of the plug rod 21 is fixedly connected to a baffle 19, the other side of the outer side of the plug rod 21 is sleeved with a spring 20, and a blocking block 18 is arranged on the top of the baffle 19.

[0035] Specifically, when the need to replace the scraper 7 arises, the operator can start the replacement process by pulling the plug rod 21. This action will cause the baffle 19 to slide outward, and the spring 1 20 will be compressed to store energy. When the plug rod 21 is completely disengaged from the connecting rod 14, the blocking block 18 will slide from the thin shell 2 17 into the thin shell 16 to ensure that after the hand is released, the baffle 19 and the plug rod 21 will not be accidentally reinserted into the connecting rod 14 due to the rebound of the spring 1 20, thereby preventing confusion. When installing a new scraper 7, you only need to gently lift the blocking block 18. Under the restoring force of the spring 1 20, the baffle 19 and the plug rod 21 will automatically move inward and accurately embed into the connecting rod 14, thereby completing the installation of the new scraper shell 15. The entire process is precisely designed and easy to operate.

[0036] Reference Figure 4 The scraper assembly includes a scraper 7, the outer side of the scraper 7 is slidably connected to the inside of the scraper shell 15, and the bottom of the scraper 7 is fixedly connected to a plurality of springs three 4, and one end of the spring three 4 is fixedly connected to the inner wall of the scraper shell 15.

[0037] Specifically, the main function of the scraper 7 is to scrape off the ice and snow accumulated on the contact network through its contact with the contact network during the operation of the electric locomotive, so as to maintain good electrical contact and ensure the continuity and efficiency of power transmission. A plurality of springs 3 4 are fixed at the bottom of the scraper 7. The function of these springs is to provide elastic support so that the scraper 7 can apply appropriate force on the ice layer of the contact network for scraping, and can also buffer and absorb the impact generated during the scraping process, reducing wear on the equipment. One end of the spring 3 4 is fixed to the inner wall of the scraper shell 15, ensuring the stability and correct movement of the scraper 7.

[0038] Reference Figure 2 - Figure 5 The bottom end of the pull rod 8 is rotatably connected to the middle part of the left side of the base frame 1, the outer side of the moving block 13 is slidably connected to the inside of the connecting plate 12, one end of the spring 20 is fixedly connected to the middle part of the baffle 19, and the other end of the spring 20 is fixedly connected to the inner wall of the thin shell 16, the plug-in rod 21 passes through the moving block 13 and is plugged into the inside of the connecting rod 14, the outer side of the baffle 19 is slidably connected to the inside of the thin shell 16, the upper side of the blocking block 18 is slidably connected to the inside of the thin shell 2 17, the lower side of the blocking block 18 is slidably connected to the thin shell 16, and one side of the thin shell 2 17 is fixedly connected to the outside of the moving block 13.

[0039] Specifically, the pull rod 8 is designed to be located in the middle of the left side of the base frame 1, and its rotational connection helps to adjust and control the position of the moving block 13 so as to maintain contact with the connecting plate 12. The moving block 13 slides on the outside and inside the connecting plate 12, ensuring the flexibility and stability of the device. The spring 1 20 plays a key buffering and stabilizing role. One end of it is fixed to the middle of the baffle 19, and the other end is fixed to the inner wall of the thin shell 16, ensuring that the plug-in rod 21 can smoothly enter and exit the connecting rod 14 during the replacement or installation of the scraper 7. The plug-in rod 21 passes through the moving block 13 and is connected to the connecting rod 14, making the operation of replacing the scraper 7 smoother. The baffle 19 can slide inside the thin shell 16, and the blocking block 18 slides up and down between the thin shell 16 and the thin shell 2 17, playing the role of locking and unlocking to prevent misoperation.

[0040] Working principle: When in use, the staff first makes the pantograph contact with the contact network, and then starts the electric locomotive. During the operation of the electric locomotive, the high-speed movement between the motor vehicle and the cable scrapes off the ice surface on the outside of the cable. Under the action of spring three 4, the scraper 7 is always in contact with the contact network, and the ice on the contact network is scraped more cleanly. When the direction of the motor vehicle track changes, the scraper shell 15 and the moving block 13 will form an angle with the cable. Under the action of the cable, the connecting rod 14 and the moving block 13 drive the sliding moving block 13 to slide inside the connecting plate 12 and squeeze the vibration shell 26. At this time, the rotating rod 31 rotates, thereby driving the slider 28 to move relative to the slide rod 27, thereby compressing the spring two 22. At the same time, the outer side of the moving shaft 25 slides on the outer side of the fixed plate 23, so that the fixed plate 23 slides on the outer side of the fixed seat 29, which protects the ice on the cable and the vibrating scraper 7 and makes it fall. When the scraper blade 7 needs to be replaced, the operator can pull the plug rod 21. This action will drive the baffle 19 to move outward, and the spring 1 20 will be compressed at the same time, until the plug-in rod 21 completely leaves the connecting rod 14, and the blocking block 18 will slide from the inside of the thin shell 17 into the thin shell 16. This design prevents the baffle 19 and the plug-in rod 21 from penetrating the moving block 13 and re-entering the connecting rod 14 under the elastic force of the spring 1 20 after the hand is released. When a new scraper 7 needs to be installed, it is only necessary to pull the blocking block 18 upward. At this time, under the elastic force of the spring 1 20, the baffle 19 and the plug-in rod 21 will move inward until they are firmly plugged into the connecting rod 14, completing the installation.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
