Description

Technical Field

[0001] This utility model relates to the field of railway passenger car technology, and in particular to a railway passenger car electrical control cabinet assembly line. Background Technology

[0002] With the rapid development of the railway transportation industry, the production scale of railway passenger car electrical control cabinets is constantly expanding, placing higher demands on the efficiency and adaptability of assembly lines. However, existing railway passenger car electrical control cabinet assembly lines have many shortcomings.

[0003] On the one hand, traditional assembly lines often use fixed-height work platforms. When assembling electrical control cabinets of different specifications, workers need to frequently adjust their posture or use auxiliary tools to complete the operation. This not only increases labor intensity but also easily leads to operational errors, affecting assembly quality and efficiency. For example, when assembling taller electrical control cabinets, workers need to bend over, which can easily cause physical fatigue after prolonged work; while when assembling shorter control cabinets, they need to raise their arms, which also reduces work efficiency.

[0004] On the other hand, existing fixing components are mostly standardized structures, making it difficult to adapt to the fixing requirements of electrical control cabinets of different sizes. Due to the diverse size specifications of railway passenger car electrical control cabinets, fixing components cannot be precisely matched, which can easily lead to insecure fixing. This can cause the control cabinet to shift or shake during assembly, affecting the installation accuracy of components and even potentially causing damage to components. Utility Model Content

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.

[0029] Reference Figures 1-4An embodiment of this utility model includes a base plate 1, a lifting assembly connected to the top surface of the base plate 1, an assembly platform 4 connected above the lifting assembly, and a fixing assembly connected to the assembly platform 4. Activating the fixing assembly fixes the electrical control cabinet, adapting to the fixing requirements of electrical control cabinets of different sizes and preventing displacement or shaking of the control cabinet during assembly. The fixing assembly includes a motor 8 fixed to a corner of the top surface of the assembly platform 4, a threaded rod 5 fixed to the output end of the motor 8, a threaded plate 13 threadedly connected to the external thread of the threaded rod 5, a fixing plate 7 fixed to one end of the threaded plate 13, a sliding plate 12 fixed to the end of the fixing plate 7 away from the threaded plate 13, a sliding rod 9 slidably connected to the sliding plate 12, a fixing plate 6 fixed to one side of the top surface of the assembly platform 4, and a threaded hole on the threaded plate 13, with the threaded rod 5 threadedly connected inside the threaded hole.

[0030] The lifting assembly includes a cylinder 23 fixedly installed on the inner wall of one side of the housing 2. A movable plate 22 is fixedly connected to the free end of the cylinder 23. An adjusting frame 20 is rotatably connected to the inner bottom surface of the housing 2. A sliding column 21 is fixedly connected to the top of the movable plate 22 and is slidably connected within the adjusting frame 20. A connecting plate 14 is connected inside the housing 2. A connecting groove 18 is formed on the bottom surface of the connecting plate 14. A connecting block 19 is rotatably connected to one end of the adjusting frame 20 and is slidably connected within the connecting groove 18. A support block 3 is fixedly connected to the top of the connecting plate 14. The top of the support block 3 penetrates the top wall of the housing 2 and extends to the top of the housing 2, where it is fixedly connected to the bottom surface of the assembly platform 4. The bottom end of the movable plate 22 is fixedly connected to a movable block 24. The inner bottom surface of the box 2 is provided with a movable groove 17. The movable block 24 is slidably connected in the movable groove 17. Both sides of the connecting plate 14 are fixedly connected to sliding blocks 15. Both sides of the inner wall of the box 2 are provided with sliding grooves 16. The two sliding blocks 15 are slidably connected in the two sliding grooves 16 respectively. The end of the threaded rod 5 away from the motor 8 is rotatably connected to a fixed block 21. The fixed block 21 is fixedly connected to the top surface of the assembly table 4. Both ends of the slide rod 9 are fixedly connected to fixed blocks 10. The two fixed blocks 10 are fixedly connected to the top surface of the assembly table 4. The slide plate 12 is provided with a sliding hole. The slide rod 9 is slidably connected in the sliding hole.

[0031] Working principle: Place the electrical control cabinet on the assembly table 4, start the motor 8, which drives the threaded rod 5 to rotate, causing the threaded plate 13 to move. The threaded plate 13 then drives the fixing plate 7 to move closer to the control cabinet. With the cooperation of the fixing plate 6 and the fixing plate 7, the electrical control cabinet can be fixed. This can adapt to the fixing requirements of electrical control cabinets of different sizes and prevent the control cabinet from shifting or shaking during the assembly process.

[0032] By activating cylinder 23, the cylinder 23 drives the moving plate 22 to move horizontally. The horizontal movement of the moving plate 22 drives the sliding column 21 to move horizontally, thereby causing the adjusting frame 20 to rotate. The rotation of the adjusting frame 20 causes the connecting block 19 to slide in the connecting groove 18, causing the connecting plate 14 to rise and fall. The rise and fall of the connecting plate 14 causes the support block 3 to rise and fall, and the rise and fall of the support block 3 causes the assembly table 4 to rise and fall. This allows the height of the electrical control cabinet to be adjusted, so that workers do not need to frequently adjust their posture or use auxiliary tools to complete the operation. This not only reduces labor intensity but also reduces the risk of operational errors, which is conducive to improving assembly quality and efficiency.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
