[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0023] A railway freight car bogie maintenance device, see Figures 1 to 3, including a base 1, a support frame 2, a steel cable 7, an electric push rod 13 and a support plate 10. The bottom of the support frame 2 is fixedly connected to the four corner edges of the top of the base 1. A top groove 201 is opened at the top of the support frame 2. The inner side of the top groove 201 is rotatably connected to a bidirectional screw rod 3, and both sides of the surface of the bidirectional screw rod 3 are penetrated by sliders 4 and are threadedly connected to the sliders 4. The bottom of the slider 4 is fixedly connected to a bottom rod 5. Winding rollers 6 are installed on both sides of the top of the support frame 2. Both ends of the steel cable 7 are fixedly connected to the winding roller 6 and the hook 8 respectively, and the steel cable 7 passes through the surface of the bottom rod 5. The hook 8 is hung on the bogie, and then the winding roller 6 starts to reel in the steel cable 7, thereby lifting the bogie during the reeling process, which is convenient for the inspection of the bottom of the bogie, and the reeling degree on both sides can also be freely adjusted, so that the bogie can be tilted laterally to adapt to different maintenance environments.

[0024] A support plate 10 is fixedly connected to the center of the top of the base 1, and support columns 1001 are fixedly connected to the four corners of the bottom of the support plate 10. The bottom of the support column 1001 is fixedly connected to the surface of the base 1, and a placement plate 12 is rotatably connected to the edge of one side of the top of the support plate 10. A through rectangular groove 11 is provided on the surface of the placement plate 12, and a groove 101 is provided on the surface of the base 1 just below the rectangular groove 11. The top of the electric push rod 13 passes through the rectangular groove 11 and is movably connected to the bottom of the placement plate 12. The bottom of the electric push rod 13 is movably connected to the inner bottom surface of the groove 101. After the electric push rod 13 is started, it will extend upward, and during the extension process, one end of the placement plate 12 will be lifted up, thereby tilting the placement plate 12 and the fixed and squeezed bogie, which makes it more convenient for the staff to inspect the surface of the bogie.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, two telescopic rods 14 are fixedly connected to the front and rear edges of the placement plate 12, and the side walls of the telescopic sections of the telescopic rods 14 are penetrated and threadedly connected with screws 15. The telescopic rods 14 can be freely adjusted in height, which can not only block the bogie in a tilted state, but also enable the screws 15 to reach a suitable extrusion position to squeeze and fix the bogie.

[0026] It is worth noting that if Figure 1 As shown, the outer wall of the support frame 2 in the horizontal position of the bidirectional screw rod 3 is fixedly connected to the servo motor 301, and the outer end of the transmission shaft of the servo motor 301 is fixedly connected to one end of the bidirectional screw rod 3. After the servo motor 301 is started, it drives the bidirectional screw rod 3 to rotate. During the rotation, the slider 4 will move with the steel cable 7 to reach a suitable hanging position. When hanging, the steel cable 7 under the bottom rod 5 is in a vertical state.

[0027] It is worth noting that if Figure 1As shown, the top surface of the bottom rod 5 on one side of the steel cable 7 is connected to a steering cylinder 9, the surface of the steering cylinder 9 is in contact with the steel cable 7, and the steering cylinder 9 changes the direction of the steel cable 7 and reduces the wear of the steel cable 7.

[0028] It is worth noting that if Figure 2 and Figure 3 As shown, the support plate 10 is located in the center of the base 1, and the support plate 10 and the placement plate 12 are in close contact with each other, thereby facilitating the placement of the bogie, preventing the bogie from rolling freely, and improving the stability of the bogie.

[0029] It is worth noting that the electric push rod 13 is located in the center of the base 1 in the left-right direction, so that the center of gravity can be kept stable when the electric push rod 13 pushes the placement plate 12.

[0030] In actual use, the bogie is placed on the surface of the placement plate 12, and then the length of the telescopic rod 14 is adjusted to make the telescopic rod 14 reach the height of the bogie, and the screw 15 is twisted to move the screw 15 toward the bogie until the bogie is squeezed. At this time, the bogie can be inspected and repaired. The bogie can be tilted by using the support plate 10, the placement plate 12 and the electric push rod 13. After the electric push rod 13 is started, it will extend upward, and during the extension process, one end of the placement plate 12 will be lifted up, thereby tilting the placement plate 12 and the fixed and squeezed bogie, which is more convenient for the staff to inspect the bogie. The surface of the bogie can be inspected and repaired, which improves the efficiency of inspection. At the same time, the bogie can be lifted by the steel cable 7, hook 8, winding roller 6, slider 4 and bottom rod 5. After the slider 4 moves to the appropriate position in the top groove 201, the winding roller 6 releases a sufficient length of the steel cable 7, and the hook 8 is hung on the bogie. Then the winding roller 6 starts to reel in the steel cable 7, thereby lifting the bogie during the reeling process, which is convenient for inspecting the bottom of the bogie. The reeling degree on both sides can also be freely adjusted, so that the bogie can be tilted sideways to adapt to different inspection environments, thereby improving the inspection efficiency of the device.

[0031] In addition, the components designed in this utility model are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in this field. Needless to say, the content protected by this utility model does not involve improvements to internal structures and methods.
