track fasteners are an integral part of the railway. The use of switches allows trains to be diverted from one track to another, creates fewer sections for the railway, and enables locomotives to turn or turn. In order to ensure the normal use of track fasteners and extend their service life, switches must be maintained regularly!

1. The small distance between the working edge of the rail should be adjusted, and it must not be greater than a deviation range allowed by the design.

2. By laying the cushion layer, the cushion layer can be increased and the level switch can be fine-tuned. Low turnout level, not exceeding design limit. The sliding bed plate should be flush, and the gap between the plate presses should not exceed the label.

3. Adjust the level limit adjustment table and make local fine adjustment to the over-limit position of the turnout direction. The straightness of the working side of the straight stranded wire should meet the specified indicators, and the bending section of the bending side of the straight stranded wire should be smooth without hard bending.

4. Distance measurement and bias voltage adjustment. The adjustment should be carried out according to the side of the linear base rail and the steps of adjusting the gauge first to make the allowable deviation between the gauge of the measuring point and the curve gauge of the guide rail meet the design requirements. Fine-tune the level switch by adjusting the buffer height. The height and level of the turnout shall not exceed the design limit. The sliding table is firm and smooth, and the gap between the pad and the workbench is not exceeding the standard.

5. Adjust the instrument. The allowable deviation of measuring point deviation and guide curve deviation can meet the design requirements. After adjusting the whole set of switches, re-tighten the spring bolt and switch pillow bolt pairs, and then tighten the torque to the design value.

Well, the above is about the maintenance of track fasteners attention to details.
