Abstract

本实用新型涉及一种带有伸缩调节功能的铁路道岔。它包括辙叉4和与辙叉配合的护轨基本轨5，护轨基本轨5与转辙基本轨2相接，转辙基本轨2后部与接于辙叉4的转辙尖轨3配合，转辙基本轨2的前部向外具有一定的倾斜角，并与连接正线的伸缩尖轨1配合。本实用新型应用简单的结构，使其具有除转辙的作用外，又具有调节钢轨伸缩的功能。在施工中可减少正线钢轨的防爬设备，降低铁路投资费用，方便线路养护和维修。

Description

带有伸缩调节功能的铁路道岔
本实用新型涉及一种带有伸缩调节功能的铁路道岔。
众所周知，常规的铁路道岔，仅具有线路转辙变线功能。而对解决采用无缝接轨的高等级线路上由温度变化所引起的钢轨伸缩带来的线路问题，没有作用。
本实用新型的目的在于针对上述问题，而提供一种同时具有转辙和调节线路钢轨伸缩功能的铁路道岔。
实现上述目的的技术方案是：一种带有伸缩调节功能的铁路道岔，包括辙叉和与辙叉配合的护轨基本轨，它设有一转辙基本轨，该基本轨的后部轨端与护轨基本轨相接，转辙基本轨内侧与接于辙叉的转辙尖轨配合，转辙基本轨的前部向外具有一定的倾斜角，并与连接正线的伸缩尖轨配合。
本实用新型的优点在于，应用简单的结构，使其具有现行铁路道岔实现转辙的作用外，又具有调节钢轨伸缩的功能。在线路施工中可减少正线钢轨的防爬设备，降低铁路投资费用，方便线路养护和维修。
附图是本实用新型结构示意图。
下面结合附图的实施例对本实用新型作进一步描述：如附图给出的，本铁路道岔包括辙叉4和与辙叉配合的护轨基本轨5，护轨基本轨5与一转辙基本轨2相接，转辙基本轨2的前部向外具有一定的倾斜角，与正线连接的伸缩尖轨1嵌于转辙基本轨2内侧，其尖轨侧斜面与转辙基本轨2的倾斜面配合。当线路钢轨伸或缩时，尖轨1与基本轨2做相对滑移。

Claims (1)

1、带有伸缩调节功能的铁路道岔，包括辙叉(4)和与辙叉配合的护轨基本轨(5)，其特征在于：它具有一转辙基本轨(2)，该转辙基本轨的后部轨端与护轨基本轨相接，转辙基本轨的内侧与接于辙叉的转辙尖轨(3)配合，转辙基本轨的前部向外具有一定的倾斜角，并与连接正线的伸缩尖轨(1)配合。
