一、问题的提出: 蒸汽机车目前仍然是我国铁路运输的主要动力,随着国民经济的改革和深入发展,中间站调车作业将会逐步增加,而中间站的调车作业是由本务机担任的。在北方的冬季,前进型蒸汽机车在中间站调车作业时,逆向推进通过道岔时发生脱轨现象在前几年是时有发生的。 本文在排除线路原因的情况下,根据蒸汽机车构造的特点和机车状态,以及气候条件的影响分析脱轨的原因。并提出相应的防 First, the issue put forward: Steam locomotive is still the main power of China’s railway transport, with the reform and deepening of the national economy, shunting operations will gradually increase the intermediate station, and the shunting operation of the intermediate station is served by the local machine of. In the northern winter, when a forward steam locomotive was shunted at a middle station, derailment occurred while reversing the turnout through turnouts. In this paper, the reasons for the exclusion of the line, according to the characteristics of steam locomotive structure and locomotive status, and the impact of climatic conditions analysis of the reasons for derailment. And put forward the corresponding defense
