Description

铁路钢轨接头 技术领域：
本发明属于铁路运输技术领域， 特别涉及铁路建设中的钢轨接头技术， 即 一种新型的铁路钢轨接头。
技术背景：
目前， 在我国铁路建设中所使用的钢轨的切面一般都是 "工"字形， 分为 与车轮接触的轨头， 中间的轨腰及底部的轨底， 而一节钢轨与另一节钢轨的接 头， 都是一个齐头的平面， 在一节钢轨与另一节钢轨接头时， 都是两个齐头的 平面连接， 再用钢板和镙丝固定。 这种接头的技术缺陷是， 当火车轮子经过钢 轨时是同时经过钢轨的接头， 这样既增大了火车轮子与钢轨接头的磨擦力， 又 产生了很强的音响， 即燥音， 随着我国火车生产技术的不断提高， 火车的速度 也不断提高， 我国自行研制的 "和谐"号火车最高时速可达到每小时 250公里。 同时， 我国还正在研制时速达 350公里以上的高速火车， 随着人们生活水平的 不断提高， 乘座火车也要求更稳， 更舒适， 更安静。 尽管目前也有解决火车铁 轨铺设的技术方案， 如加长钢轨的长度， 但这又给铺设钢轨中带来新的技术难 题， 这是目前我国铁路运输中急需解决的问题。
发明内容：
针对目前我国铁路钢轨铺设中以上存在的问题， 本发明提供一种新的铁路 钢轨接头，本钢轨接头能够减少火车轮与钢轨接头的磨擦，提高火车行驶速度， 减少火车燥音等优点。
本发明是通过以下技术方案实现的。
一种新型的铁路钢轨接头， 它是把 "工"字形钢轨与车轮接触的轨头由平 面改为半边凸出， 半边凹进去的两个 "榫"状接头， 即 " ^ "形状， 钢轨中间 轨腰及底部不变， 凸凹的距离在 5-60mm之间。
也可将 "工"字形钢轨接触的轨头由平面改为 30 80。 的斜面接头， 斜 面的两端为直线， 直线与斜面的接头， 钢轨为直形状， 钢轨的中间轨腰及底部 不变。
本发明的另一技术方案为： 一种新型的铁路钢轨接头， 它是把 "工"字钢 轨与车轮接触的轨头由平面改为 " S "状接头， 即 " "形状， 钢轨中间轨腰 及底部不变， " S"形距离在 10-70mm之间。
铺轨时， 将任意的两个接头对齐， 放入钢板 (5)， 用螺丝 (4)固定。
4、 以设计图为基础， 根据需要可做适当的改动。
本发明的技术进歩性是， 由于火车轮经过钢轨接头不是在一个平面上， 因 此他能够减少火车轮与钢轨接头的震动磨擦， 提高火车行驶速度， 减少火车燥 音等优点。
