Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a supporting device for the completion of a rail vehicle bogie. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Rail vehicles have bogies. Currently, the bogie completion process is as follows: wheelset lifting - wheelbase placement - frame removal - correction (first lift the wheelset onto the track on the completion platform, then place and fix it according to the wheelbase, then lift the frame to remove it, and finally correct the resulting offset. For cases with large errors, the correction process cannot be completed in one go and may require multiple adjustments, which is time-consuming and labor-intensive, affecting the product production cycle).

[0004] In the prior art, a support device for completion is also used to support the bogie to facilitate the completion of the bogie. The inventors found that the current support device for completion of the bogie has the following problems:

[0005] 1. Due to the inconvenience of height adjustment and horizontal movement adjustment of the support device used for the completion of the bogie, multiple people are required to perform a long-term axle box adjustment operation when the bogie is completed.

[0006] 2. The height of some steering support devices cannot be adjusted, nor can they be moved horizontally, making the entire bogie support device non-universal.

[0007] 3. The wheelbase of the wheels cannot be guaranteed before the bogie is completed, and repeated measurements and adjustments are required, which makes the completion of the bogie take a long time and slow.

[0008] 4. After the wheelset is lifted, multiple people are required to carry out the transport of the supporting device. After the correction, the supporting device is also required to be transported manually, which results in high labor intensity.

[0009] 5. When the bogie is completed, a pry bar will be used during the correction process, and the bogie will collide with the supporting device head-on, which may easily cause damage to the rail vehicle positioning node and the lower mounting surface of the axle box body, and may also cause some of the bogie's laminated spring guide columns to be squeezed and deformed, resulting in scrapping.
