Multi-section stress relief device
The invention provides a multi-section stress relief device, which relates to the technical field of railway engineering, and comprises a first bracket, a second bracket and a variable pitch structure, the first end of the first support and the first end of the second support are fixedly connected with the two steel rails respectively. The variable-pitch structure is arranged between the second end of the first bracket and the second end of the second bracket, and the variable-pitch structure at least comprises a plurality of rib plates which are uniformly arranged at intervals; when the two sections of steel rails are stretched towards the two sides or extruded towards the middle to form large gap changes, the rib plates disperse the large gap changes into a plurality of small interval changes so as to disperse rail stress. The problems that stress is concentrated and maintenance is difficult due to the fact that stress relief is conducted through a single expansion joint in the prior art are solved. According to the change of tension and pressure, the expansion amount of a large expansion joint is converted into the expansion amount of a plurality of small expansion joints, so that the track stress is effectively dispersed, and the stability and the safety of a seamless track of a railway are improved.
本发明提供了一种多段式应力放散器，涉及铁路工程技术领域，包括第一支架、第二支架和变距结构；第一支架的第一端和第二支架的第一端分别与两段钢轨固定连接；变距结构设置于第一支架的第二端和第二支架的第二端之间，变距结构至少包括均匀间隔设置的多个筋板；当两段钢轨向两侧拉伸或向中间挤压形成较大的缝隙变化时，多个筋板将较大的缝隙变化分散为多个较小的间隔变化，以分散轨道应力。本发明解决了现有技术中通过单一的伸缩缝来进行应力放散，存在应力集中、维护困难的问题。本发明根据拉压力的变化，将一个大的伸缩缝的伸缩量转化为多个小的伸缩缝的伸缩量，从而实现对轨道应力的有效分散，提高铁路无缝线路的稳定性和安全性。
