Steel rail gauge adjusting method suitable for rail with baffle parts

Abstract

The invention discloses a steel rail gauge adjusting method suitable for a rail with baffle parts, and belongs to the technical field of rail fasteners. By arranging gauge adjusting units composed ofgauge baffles and insulated gauge blocks and selecting the sizes of the gauge baffles and / or the insulated gauge blocks, the steel rail gauge can be effectively adjusted. The steel rail gauge adjusting method is implemented by adopting a fastener system with the gauge adjusting units and is simple in step and convenient to operate, a steel rail is effectively correspondingly arranged on a rail sleeper with the baffle parts, the arrangement process is simple, the reliability is high, transverse gauge adjustment of the steel rail can be correspondingly achieved by arranging the gauge adjusting units, the flexibility of an adjustment scheme is high, the gauge adjusting range is large, the gauge adjusting requirements of the steel rail can be fully met, the accuracy and efficiency of steel rail gauge adjustment are improved, material waste during steel rail gauge adjustment is reduced, the cost of steel rail gauge adjustment is saved, and thus the steel rail gauge adjusting method has goodapplication prospects and good application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of rail fasteners, and in particular relates to a method for adjusting the gauge of steel rails suitable for rails with shoulders. 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...

AI Technical Summary

Problems solved by technology

However, in the prior art, the gauge adjustment of the rail is often through the overall replacement of the gauge baffle, and the replaced gauge baffle cannot be used again and needs to be scrapped directly, resulting in an extreme waste of resources; at the same time, due to The specifications of the gauge baffles in the prior art are often less, so that the flexibility of gauge adjustment is limited, and the accuracy of gauge adjustment cannot be fully guaranteed; moreover, when using the existing gauge baffles for gauge adjustment, often It is necessary to dismantle the fastener system as a whole for corresponding adjustments, resulting in low adjustment efficiency of the rails and increased maintenance costs of the rails

Therefore, the existing fastener system has certain application limitations, and cannot fully satisfy the rapid and accurate adjustment of the rail gauge on the ballastless track.
