The height-adjusting pad mainly has the following functions:
I. Adjusting track height
Compensating for track subsidence:
In railway tracks or other similar track systems, due to long-term bearing of the weight of trains and the influence of various natural factors, tracks may sink to different degrees. The height-adjusting pad can compensate for the subsidence amount of the track by increasing the height at the bottom of the track, ensuring that the height of the track meets the design requirements and guaranteeing the smoothness and safety of train operation.
For example, in some areas with poor geological conditions, track subsidence may be more obvious. Using height-adjusting pads can be adjusted in time to avoid affecting train operation due to excessive changes in track height.
Adapting to different line conditions:
During the construction and maintenance of railway lines, different topographies and line requirements may be encountered. The height-adjusting pad can adjust the height of the track according to specific line conditions, so that the track can adapt to different slope and curve radius requirements.
For example, in mountain railways, due to large terrain fluctuations, the height of the track needs to be finely adjusted to ensure that trains can safely pass through different sections.
II. Improving track smoothness
Reducing track irregularities:
During the use of tracks, local unevenness may occur, which will cause bumps and vibrations during train operation. The height-adjusting pad can make the track surface more flat by adjusting the height of the track, reducing the impact of track irregularities on train operation.
For example, at track joints or due to reasons such as construction quality, resulting in track height differences, height-adjusting pads can be used for adjustment to improve track smoothness.
Improving train operation comfort:
Good track smoothness can significantly improve the comfort of train operation and reduce passengers’ discomfort. The use of height-adjusting pads can effectively improve track smoothness, reduce vibrations and noise during train operation, and provide passengers with a more comfortable riding environment.
For high-speed trains, track smoothness is particularly important. The precise adjustment of height-adjusting pads can ensure the stability and safety of trains when running at high speeds.
III. Facilitating track maintenance
Simplifying maintenance operations:
When tracks need maintenance and adjustment, height-adjusting pads can provide a convenient adjustment method. Compared with other complex track adjustment methods, using height-adjusting pads can quickly and effectively adjust the track height, reducing the time and difficulty of maintenance operations.
For example, in daily track inspections, if problems with track height are found, height-adjusting pads can be directly installed or replaced on site without large-scale construction.
Reducing maintenance costs:
The use of height-adjusting shims can extend the service life of tracks and reduce the number and cost of track repairs. By adjusting the track height in time, damage caused by excessive changes in track height can be avoided, reducing the cost of track maintenance.
In addition, the cost of height-adjusting pads is relatively low, and installation and replacement are relatively convenient, which is conducive to reducing the overall cost of track maintenance.
