Abstract

The invention discloses a rail height adjusting method suitable for a rail with baffle parts, and belongs to the technical field of rail fasteners. By correspondingly arranging an under-rail cushion plate, an under-rail fine-adjustment cushion plate and first height adjusting cushion plates, preferably setting the sizes of all the cushion plates and selecting corresponding cushion plates in adjustment processes, steel rail height adjustment within the range of -4 mm to 22 mm is effectively achieved. The rail height adjusting method is implemented by adopting a fastener system comprising the under-rail cushion plate, the under-rail fine-adjustment cushion plate and the first height adjusting cushion plates and is simple in step and convenient to operate, the height of a steel rail on a railsleeper with the baffle parts is effectively adjusted, the adjustment process is simple, the reliability is high, the height adjustment range of the steel rail is wide, the flexibility of an adjustment scheme is high, the height adjusting requirements of the steel rail can be fully met, the accuracy and efficiency of steel rail height adjustment are improved, and thus the rail height adjusting method has good application prospects and high application and popularization value.

Description

technical field

[0001] The invention belongs to the technical field of track fasteners, and in particular relates to a track height adjustment method suitable for a track with a shoulder stop. Background technique

[0002] In the ballastless track, the fastener system is widely used. As the intermediate connecting part of the rail and the sleeper, it plays the role of fixing the rail to the sleeper, and prevents the longitudinal and lateral movement of the rail relative to the sleeper while maintaining the gauge. Move to achieve a stable setting of the rail on the sleeper.

[0003] Since most of the existing ballastless tracks use concrete sleepers, the sleeper’s elasticity is poor, so the fastener system is required to provide a certain degree of elasticity while ensuring sufficient strength and durability; at the same time, since the ballastless track may There are certain differences, such as differences in height, lateral offset, etc. Therefore, in order to ensure the a...
