Turnout switch rail structure of heavy haul railway and design method thereof
The invention provides a heavy haul railway turnout switch rail structure and a design method thereof. The heavy haul railway turnout switch rail structure comprises a switch rail front section and a switch rail rear section. The switch rail front section and the switch rail rear section are spliced to form the whole switch rail; the joint part of the switch rail front section and the switch rail rear section is arranged on the 30-70mm section of the switch rail; connecting clamping plates are arranged at the connecting parts; the connecting part is arranged on the upper plane of a sliding bed bedplate of the turnout sliding bed bedplate; the connecting clamping plate comprises a non-working side clamping plate and a working side clamping plate; and the non-working edge side clamping plate and the working edge side clamping plate are used for oppositely clamping and splicing the joint part of the switch rail front section and the switch rail rear section by using a fastener to form the whole switch rail. The method solves the technical problem that the overall service life of the switch rail is short due to the fact that the whole switch rail is judged to be seriously damaged and then departs due to the fact that the heavy-load line turnout switch rail is locally and rapidly abraded. The method is suitable for on-line replacement of switch rails of all common-speed turnouts at the present stage, and is especially suitable for heavy-load lines with fast abrasion in a small-section range of the switch rails; the service life of the whole switch rail is effectively prolonged, and the switch rail replacement cost is reduced.
提供一种重载铁路道岔尖轨结构及其设计方法，包括尖轨前段和尖轨后段两部分；尖轨前段与尖轨后段拼接组成整根尖轨；且尖轨前段与尖轨后段的衔接部位设置于尖轨30～70mm断面；衔接部位设有连接夹板；衔接部位设于道岔滑床垫板的滑床台板上平面；连接夹板包括非工作边侧夹板和工作边侧夹板；非工作边侧夹板与工作边侧夹板使用紧固件将尖轨前段与尖轨后段衔接部位对夹拼接形成整根尖轨。本发明解决重载线路道岔尖轨普遍因局部快速磨耗而导致整根尖轨判定为重伤后下道，导致尖轨总体使用寿命较短的技术问题；适用于现阶段所有普速道岔的尖轨在线更换，尤其适用于尖轨小断面范围内磨耗较快的重载线路；有效提高整根尖轨使用寿命，降低尖轨更换成本。
