[0002] The carbon contact plate of the pantograph is a key component on the pantograph of electric traction vehicles such as electric locomotives, EMUs, and trams. It is mainly used to contact the contact wire and transmit electrical energy. It is made of high-purity carbon material and has good conductivity, wear resistance and self-lubricating properties. It can reduce wear on the contact wire during high-speed operation and ensure stable power transmission. The design of the carbon contact plate must take into account strength, heat resistance and impact resistance to adapt to different operating environments and conditions. It is an important component to ensure the efficient operation of the electric traction system.
[0003] During the maintenance of pantograph carbon contactors, operators often need to use corresponding automatic replacement devices to replace them. Although existing replacement devices have basic replacement functions, they can generally only be used in fixed locations and are difficult to move. This results in poor adaptability of the device, which cannot meet the complex operating environment and operational requirements. Therefore, it is necessary to improve it. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 6 As shown, this utility model provides an adaptive positioning automatic replacement device for a pantograph carbon sliding plate, including a mobile trolley body 1. A fixed frame 2 is fixedly connected to the left side of the top of the mobile trolley body 1. A first motor 3 is fixedly connected to the top of the fixed frame 2. A first rotating shaft 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. The other end of the first rotating shaft 4 passes through the fixed frame 2 and extends into the inner cavity of the fixed frame 2, and a rotating rod 5 is fixedly sleeved thereon. A sleeve rod 6 is movably connected to the outer surface of the rotating rod 5. A connecting plate 7 is fixedly connected to the right side of the sleeve rod 6. A base 8 is fixedly connected to the right side of the connecting plate 7. The bottoms of the sleeve rod 6 and the connecting plate 7 are movably connected to the top of the mobile trolley body 1. The bottom end of the base 8 is movably connected to the interior of the top of the mobile trolley body 1. When the first motor 3 starts running, the first rotating shaft 4 will drive the rotating rod 5 to rotate, and the rotating rod 5 will squeeze and push the sleeve rod 6, thereby causing the sleeve rod 6 to drive the connecting plate 7 and the base 8 to move horizontally to the right under the limiting action of the mobile trolley body 1.
[0023] The base 8 is fixedly connected to the top of the mounting frame 9, and the mounting frame 9 is fixedly connected to the top of the mounting frame 9. The other end of the output shaft of the second motor 10 is fixedly sleeved with a first threaded rod 11. The bottom end of the first threaded rod 11 passes through the mounting frame 9 and extends to the top of the base 8 and is threadedly sleeved with a fixing block 12. A limit rod 13 is fixedly installed between the mounting frame 9 and the base 8. The outer surface of the limit rod 13 is movably sleeved with the inside of the fixing block 12. When the second motor 10 starts running, the first threaded rod 11 will start running, which will cause the fixing block 12 to move vertically upward under the limiting action of the limit rod 13.
[0024] The fixed block 12 is fixedly connected to the right side of the connecting frame 14. The front of the inner cavity of the connecting frame 14 is fixedly connected to the third motor 15. The other end of the output shaft of the third motor 15 is fixedly sleeved with the second threaded rod 16. The other end of the second threaded rod 16 passes through the connecting frame 14 and extends into the interior of the connecting frame 14 and is threadedly sleeved with the moving block 17. The outer surface of the moving block 17 is movably connected to the inner surface of the connecting frame 14. When the third motor 15 starts to run, the second threaded rod 16 will start to run, thereby causing the two moving blocks 17 to move towards each other under the limiting effect of the connecting frame 14.
[0025] The right side of the movable block 17 is hinged with a diagonal rod 18, and the other end of the diagonal rod 18 is hinged with a movable frame 19. The bottom of the connecting frame 14 is fixedly connected with a fixed rod 20, and the outer surface of the fixed rod 20 is movably sleeved with the inside of the movable frame 19. When the two movable blocks 17 move towards each other, the two diagonal rods 18 will move and squeeze and push the movable frame 19 to move horizontally to the right under the limiting action of the fixed rod 20.
[0026] The top of the movable frame 19 is fixedly connected to a first protective shell 21. A fourth motor 22 is fixedly installed inside the first protective shell 21. The other end of the output shaft of the fourth motor 22 is fixedly sleeved with a second rotating shaft 23. The other end of the second rotating shaft 23 is fixedly sleeved with a rotating rod 24. Connecting rods 25 are hinged to both sides of the rotating rod 24. The other end of the connecting rod 25 is hinged to a vertical rod 26. The outer surface of the vertical rod 26 is movably connected to the interior of the top of the movable frame 19. When the fourth motor 22 starts running, it will cause the second rotating shaft 23 to drive the rotating rod 24 to rotate, and cause the two connecting rods 25 to move. Finally, the two vertical rods 26 will move horizontally towards each other under the limiting action of the movable frame 19.
[0027] The inner cavity of the movable frame 19 is movably connected to a second protective shell 27. The top of the second protective shell 27 is fixedly connected to the bottom of the vertical rod 26. A fifth motor 28 is fixedly installed inside the second protective shell 27. The other end of the output shaft of the fifth motor 28 is fixedly sleeved with a third rotating shaft 29. The other end of the third rotating shaft 29 is fixedly connected to a wrench 30. When the vertical rod 26 moves, it will drive the second protective shell 27 to move horizontally back and forth under the limiting action of the movable frame 19. When the fifth motor 28 starts running, it will cause the third rotating shaft 29 to drive the wrench 30 to rotate.
[0028] There are two movable blocks 17, both of the same size and both with smooth surfaces. This design makes the movement of the movable blocks 17 inside the connecting frame 14 smoother, reduces the friction between the movable blocks 17 and the connecting frame 14, and improves the service life of the movable blocks 17.
[0029] Working principle and usage process of this utility model:
[0030] First, after moving the trolley body 1 to the designated position, the second motor 10 is started, which causes the first threaded rod 11 to rotate and the fixed block 12 to move vertically upward under the limiting action of the limiting rod 13. Finally, the moving frame 19 moves the wrench 30 upward together and moves the wrench 30 to the same height as the bolt to be removed. Then, by starting the third motor 15, the second threaded rod 16 is rotated, and the two moving blocks 17 move towards each other. The two inclined rods 18 press and push the moving frame 19, which moves horizontally to the right under the limiting action of the fixed rod 20. Finally, when the bolt enters the wrench 30, the fifth motor 28 is started, which causes the third rotating shaft 29 to rotate the wrench 30, realizing the replacement operation.
[0031] When the bolt to be removed is located far away, starting the first motor 3 will cause the first rotating shaft 4 to rotate the rotating rod 5, which in turn pushes the sleeve rod 6. This causes the sleeve rod 6 to move the connecting plate 7 and the base 8 horizontally to the right under the limiting action of the moving trolley body 1. Ultimately, this allows the wrench 30 to slide horizontally to the right along the top of the moving trolley body 1, facilitating the replacement of pantograph carbon contact plates at more distant locations. This improves the adaptability of the device and allows it to adapt to complex operating environments. When the specifications of the pantograph carbon sliding plate are different, causing the installation spacing of the two sets of bolts to change, the fourth motor 22 is started. This causes the second rotating shaft 23 to drive the rotating rod 24 to rotate, and causes the two connecting rods 25 to move. Finally, the two vertical rods 26 drive the two second protective shells 27 to move horizontally towards each other under the limiting action of the moving frame 19. This achieves the purpose of adjusting the spacing of the two wrenches 30, further improving the adaptability of the device and enabling it to adapt to the replacement operation of pantograph carbon sliding plates of various specifications.
