Description

Technical Field

[0001] This utility model relates to the field of EMU (Electric Multiple Unit) frame maintenance technology, and more specifically, to an EMU frame maintenance support device. Background Technology

[0002] The train frame is an important component of the train bogie, mainly responsible for supporting the car body, transmitting loads, providing steering and vibration reduction functions. The frame is the foundation of the train bogie, supporting the weight of the entire car body, and transmitting the vertical load, longitudinal force and lateral force of the car body to the wheelsets and tracks. Through cooperation with the wheelsets and suspension system, the train can be steered. The frame and suspension system work together to reduce the vibration of the car body during operation and improve passenger comfort.

[0003] When inspecting the locomotive of a high-speed train, the lack of a structure to prevent displacement of the train frame means that most existing high-speed trains are parked directly on the tracks in the maintenance workshop for frame inspection, and the frame is inspected manually from below the train. There is no way to support the train frame to prevent displacement, so if the train moves unexpectedly during the maintenance process due to other factors, it can easily threaten the personal safety of the maintenance personnel.

The bogie 9 is provided with a steering groove 15, and the steering groove 15 is provided with a steering hole 16 that cooperates with the moving block 14. The steering rod 8 is symmetrically provided with a sliding groove 17 that cooperates with the moving block 14. A moving rod 18 is slidably provided on the steering rod 8. One end of the moving rod 18 is fixedly connected to the moving plate 13, and the other end is provided with a pressing head 19. The support rail 3 is provided with a sliding groove 20, and a sliding block 21 is provided on the sliding groove 20. The sliding frame 7 is fixedly provided on the sliding block 21. The maintenance groove 2 is symmetrically provided with support rods 22, and the support rods 22 are supported and provided below the support rail 3.

[0030] In this embodiment, when the main frame 5 is being inspected, the locomotive body 4 is moved above the inspection slot 2 via the support rail 3. The position of the sliding frame 7 is adjusted by moving the sliding block 21 within the sliding slot 20. The pressing head 19 is pressed down, which drives the moving rod 18 and the moving plate 13 to move downward and compress the moving spring 12. The moving block 14 moves downward along the moving slide 17. At the same time, the moving block 14 moves from the turning hole 16 into the turning slot 15. The bogie 9 and the iron shoe 10 are rotated so that the iron shoe 10 extends into both sides of the traveling wheel 6. Then the pressing head 19 is released, and the moving plate 13, under the elastic force of the moving spring 12, drives the moving block 14 to move upward, so that the moving block 14 extends into the turning hole 16, fixing the rotation direction of the bogie 9 and the iron shoe 10, thereby fixing the position and direction of the iron shoe 10.

[0031] Please see Figure 5 As one embodiment for fixing the sliding frame 7: the sliding frame 7 is provided with an adjusting screw 23, a limiting block 24 is threadedly connected to the adjusting screw 23, a limiting rod 25 is slidably provided on the limiting block 24, a limiting hole 26 is provided on the support rail 3 to cooperate with the limiting rod 25, a limiting groove 27 is provided in the limiting block 24, a limiting plate 28 is fixedly provided on the limiting rod 25 in the limiting groove 27, and a limiting spring 29 is provided between the limiting plate 28 and the limiting groove 27.

[0032] More specifically, when fixing the positions of the sliding block 21 and the sliding frame 7, the limiting rod 25 is pulled outward. The limiting rod 25 drives the limiting plate 28 to compress the limiting spring 29. The adjusting screw 23 is rotated, and the adjusting screw 23 drives the limiting block 24 to move. When the limiting rod 25 is aligned with the limiting hole 26, the limiting rod 25 extends into the limiting hole 26 under the elastic force of the limiting spring 29, fixing the positions of the limiting block 24 and the sliding frame 7, which facilitates the maintenance of the train body 4.

[0033] In summary, during the use or operation of the overall equipment: when the main frame 5 is being inspected, the locomotive body 4 is moved above the inspection slot 2 via the support rail 3. The position of the sliding frame 7 is adjusted by moving the sliding block 21 within the sliding slot 20. The pressing head 19 is pressed down, which drives the moving rod 18 and the moving plate 13 to move downward and compress the moving spring 12. The moving block 14 moves downward along the moving slide 17. At the same time, the moving block 14 moves from the turning hole 16 into the turning slot 15. The bogie 9 and the iron shoe 10 are rotated so that the iron shoe 10 extends into both sides of the traveling wheel 6. Then the pressing head 19 is released, and the moving plate 13, under the elastic force of the moving spring 12, drives the moving block 14 to move upward, so that the moving block 14 extends into the turning hole 16, fixing the rotation direction of the bogie 9 and the iron shoe 10, thereby fixing the position and direction of the iron shoe 10.

[0034] When the sliding block 21 and the sliding frame 7 are in the fixed position, the limiting rod 25 is pulled outward. The limiting rod 25 drives the limiting plate 28 to compress the limiting spring 29. The adjusting screw 23 is rotated, and the adjusting screw 23 drives the limiting block 24 to move. When the limiting rod 25 is aligned with the limiting hole 26, the limiting rod 25 extends into the limiting hole 26 under the elastic force of the limiting spring 29, fixing the position of the limiting block 24 and the sliding frame 7, which facilitates the maintenance of the train body 4.
