Groove type integral tramcar turnout wear-resistant guard rail and machining method thereof
The invention discloses a shallow groove type integral tramcar turnout wear-resistant guard rail and a processing method thereof.The guard rail comprises a straight guard rail and a curved guard rail, the two guard rails are both made of channel steel, a wear-resistant strip is fixedly arranged on the rail lip plane of the channel steel rail, the distance between the starting point of the wear-resistant strip and the front end of the guard rail is 390-395 mm, and the distance between the starting point of the wear-resistant strip and the front end of the guard rail is 390-395 mm. According to the guard rail, the wear-resistant strip is arranged on the rail lip, the guard rail is good in compatibility with an existing guard rail base plate and an existing fastener, the strength is high, the wear resistance is good, the maintenance workload is reduced, and the service life is prolonged. When the guard rail is machined, the positioning step is machined on the plane of the rail lip, the positioning groove in the wear-resisting strip is machined at the same time, then welding, preheating before welding and machining after welding are conducted to determine the final size, the machining method is short in technological process, easy to operate and few in step, welding cracks can be avoided, and the machining efficiency is improved. And the wear-resisting strip and the steel rail are firmly combined, durability is good, desoldering is not prone to occurring, and the service life is long.
本发明公开一种浅槽型整体式有轨电车道岔耐磨护轨及其加工方法,护轨包括直向护轨和曲向护轨,两护轨均采用槽型钢,在槽型钢轨的上的轨唇平面上固定设置有耐磨条,所述耐磨条的起点距离护轨前端390~395mm,该耐磨条的起始端和末尾端的顶面具有过度段,该护轨在轨唇上设置耐磨条,与现有护轨垫板和及扣件相容性好、强度高、耐磨性好,减少养护工作量,延长使用寿命。加工该护轨时,先在轨唇平面上加工出定位台阶,同时加工出耐磨条上的定位槽,然后焊接,焊接前预热,焊接后进行机加工以确定最终尺寸,该加工方法工艺流程短、操作简单、步骤少,能够避免焊接裂纹的产生,并且耐磨条和钢轨结合牢固、耐久性好,不易脱焊,适用寿命长。
