A track height adjustment method suitable for a track with a shoulder

Abstract

The invention discloses a method for adjusting the height of a track suitable for a track with a shoulder, which belongs to the technical field of track fasteners. The under-rail backing plate, the under-rail fine-tuning backing plate and the first height-adjusting backing plate are arranged correspondingly, and through optimal setting The size of each backing plate, and the corresponding backing plate is selected during the corresponding adjustment process, so as to effectively realize the rail height adjustment of the rail within ‑4mm to 22mm. The track height adjustment method of the present invention is realized by using the fastener system with the under-rail backing plate, the under-rail fine-tuning backing plate and the first height-adjusting backing plate, the steps are simple, the operation is convenient, and the rail is effectively realized The height adjustment of the rail on the track has a simple adjustment process and high reliability, and the height adjustment range of the rail is wide, and the flexibility of the adjustment scheme is high, which can fully meet the height adjustment requirements of the rail and improve the accuracy and efficiency of the height adjustment of the rail. The application prospect and promotion application 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...

Problems solved by technology

However, in the prior art, the track height adjustment of the rail is often through the overall replacement of the under-rail backing plate, and the replaced under-rail backing plate often 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 under-rail backing plates in the prior art are often less, so that the flexibility of track height adjustment is limited, and the accuracy of track height adjustment cannot be fully guaranteed; moreover, when using the existing fastener system for track height adjustment, it is often necessary to The entire fastener system is removed for corresponding adjustments, resulting in low efficiency of track height adjustment and increased rail maintenance costs

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