spring plate series is a relatively weak link on the rail, because the whole rail is paved in one piece, only the spring plate series is paved on the rail, and it is particularly critical to do a good job of tightening the spring plate series when paving. As a big railway country in China, in order to facilitate people's travel, railway tracks are more diverse. For different types of tracks, the spring plate series models of pavement are also different. Then in addition to the spring plate series model, you should also know some spring plate series maintenance methods.

What are the curing methods of spring plate series?

First, pull the general direction of the spring plate series, so that the spring plate series is in the correct position, and the front and back lines are connected straight, without bending and bending corners. Specifically, the straight strand is pulled first, and then the offset is determined, and then the other strands are determined through the gauge.

The spring plate series is fully rammed, the lifting amount is controlled at about 40MM, the frog center and the unwelded joint are appropriately raised a little more, the stamping of the frog and the protection rail should be uniform, the dark pit lifting plate should be eliminated, and the foundation should be solid and uniform.

For small direction, broken bend and bad gauge change rate, the hard bend of the rail is corrected by fine drawing and fine correction to achieve good direction. The gauge correction is mainly based on adjusting the gauge block, combining with the tie and adjusting the "T" bolt clearance of the backing plate.

Straightening the connecting parts, so that the fastening parts are complete, supporting use, no missing, damage, correct position, no deviation, the gauge block and the support baffle and the upper part of the rail bottom, the side are kept close.

The single opening spring plate series has main line and side line. The opening of spring plate series is realized through the action of the switch rail, and the opening of side line and main line are controlled by the transfer machine. The single opening spring plate series is the most used type of dolce in the field.

Symmetrical spring plate series is a special type of single open spring plate series. The whole spring plate series is symmetrical in the middle line of the main line or the middle branch line of the fork Angle, and there is no straight and lateral division when the train passes. When the length of the switch rail is the same, the Angle of intersection between the operating edge of the switch rail and the direction of the main line is about half of that of the single open spring plate series. When the radius of the leading curve is equal, the length of the symmetric spring plate series is shorter than that of the single open spring plate series, and the radius of the leading curve is about twice that of the single open spring plate series when other conditions are the same.
