Low stress seamless track
The invention provides a low-stress seamless track, and relates to the technical field of railway tracks, the low-stress seamless track comprises a plurality of sections of telescopic areas connected in sequence, a multi-section stress relief device is arranged between every two adjacent sections of telescopic areas, the telescopic areas are composed of steel rails, and the multi-section stress relief devices are used for releasing temperature stress in the steel rails; the expansion and contraction amount of the multi-section type stress diffusing device ranges from 0 mm to 1280 mm. The problems that in the prior art, a seamless track cannot adapt to extreme temperature changes, and the maintenance cost is high are solved. A fixed area and a buffer area in a traditional seamless track are omitted, so that the track structure is more simplified, and the maintenance cost is reduced. The telescopic area is specially designed, and the telescopic amount of dozens of millimeters to hundreds of millimeters can be achieved so as to adapt to extreme temperature changes. The stress relief device is made of a novel material, has high strength, high toughness and good weather resistance, and can effectively disperse and release temperature stress in the steel rail.
本发明提供了一种低应力无缝线路，涉及铁路轨道技术领域，包括：多段依次连接的伸缩区，每两段相邻的伸缩区之间均设置有一个多段式应力放散器，伸缩区由钢轨组成，多段式应力放散器用于释放钢轨内部的温度应力；其中，多段式应力放散器的伸缩量为0～1280mm。本发明解决了现有技术中的无缝线路无法适应极端温度变化、维护成本高昂的问题。本发明取消传统无缝线路中的固定区和缓冲区，使得线路结构更加简化，减少了维护成本。伸缩区采用特殊设计，能够实现几十到几百毫米的伸缩量，以适应极端温度变化。应力放散器采用新型材料制造，具有高强度、高韧性和良好耐候性，能够有效地分散和释放钢轨内部的温度应力。
