一、前言铁路线上的降雪和积雪为日本正在修建中的东北——上越干线上的列车运行设置了很大的障碍。大雪给铁路线路及车辆设备都带来了很大损害。雪害已成为日本国营铁路的工程师们一个十分关注的问题。日本国营铁路电力工程局于一九七○年接受研制道岔融雪机械的任务。该项任务已成为防止雪害和发展无维修线路的一个组成部分。适于日本新干线使用的各式道岔融雪器均进行了试制与试验,并且多数都取得了很好的效果。当前,道岔融雪器这项研制工作已进入了最后阶段。这篇文章将概要地介绍一种新型道岔融雪器。
I. INTRODUCTION Snowfall and snow cover on the railway line have set a great barrier to the operation of trains on the northeast-Shangjian Route under construction in Japan. Heavy snow has caused great damage to railway lines and vehicle equipment. Snow damage has become a matter of great concern to Japanese state railway engineers. Japan State-owned Railway Electric Power Engineering Bureau in 1970 to accept the task of developing turnkey snow melting machinery. This task has become an integral part of the prevention of snow damage and the development of maintenance-free routes. Suitable for Japan’s Shinkansen use of various types of turnout snow melter were trial and test, and most have achieved good results. At present, the research and development of the switch melting device has entered the final stage. This article gives an overview of a new type of turnout snow melter.
