在机务现场,因乘务员操纵不当或轮箍安装过盈量不足等原因,机车运行中会发生迟缓故障,严重时会引起轮箍外窜。机车轮箍外窜后,可维持运行的最大外窜量不得大于10mm,按此限掌握继续运行,不会对钢轨造成破坏。1 机车轮箍外窜现场的处理 现场处理有车轮技术员及抢修钳工。携带30t以上油镐两个、一号撬棍2～4个、轮对内距尺、轮对踏面轮缘测量尺、折装工具一套。当机车轮箍外窜尺寸大于10mm时,一般需进行现场处理。由于内燃机车轮对置于转向架内部,空间小,不宜采用乙炔加热的方法来恢复轮箍外窜。轮对只有两个相距180°吊装孔,受结构限制也不便采用加卡子紧固的方法。
In the locomotive scene, due to steward improper handling or insufficient installation of tire interference and other reasons, the locomotive running slow fault occurs, in serious cases will cause the wheel outside channeling. Locomotive wheel hoist channeling, can maintain the maximum amount of foreign channeling operation shall not exceed 10mm, according to this limit to continue to operate, will not cause damage to the rail. A locomotive wheel outside the channeling scene processing site with a wheel technician and repair fitter. Carrying two oil picks 30t or more, No. 1 crowbar 2 to 4, the wheel within the distance rule, the wheel on the rim measuring ruler, a set of tools. When the locomotive tire channeling channel size greater than 10mm, the general need for on-site processing. As the internal combustion engine wheels placed inside the bogie, space is small, should not be used acetylene heating method to restore the tire channeling. Only two pairs of wheel 180 ° lifting holes, by the structural constraints are also inconvenient to use plus clamp method.
