一、前言日本新干线的东北(Tohoku)、上越(Joetsu)及北海道(Hokkaido)地区降雪量较大,为排除降雪对该地区铁路运输的干扰,日本试制了一种大功率道岔除雪设备。目前,该道岔除雪设备在北海道地区已经进行了各种情况的试验。二、道岔融雪设备这种道岔融雪设备系为热风加热器与热水喷嘴装置的结合型。热风加热器主要是为了融化刚刚降落在道岔部位的积雪,而热水喷嘴融雪装置则是为了清除由除雪犁带进道岔或由运行车辆的震动从车厢底落入道岔的积雪以及由风暴吹入道岔部位的积雪。
I. Preface Japan’s Shinkansen has heavy snowfall over the Tohoku, Joetsu and Hokkaido regions. To eliminate the interference of snowfall on railway transport in the region, Japan tried out a snow removal device for high-power turnout. At present, the snow removal equipment for the switch has been tested in various situations in Hokkaido. Second, the turnout snow melting equipment This kind of turnout snow melting equipment is a combination of hot air heater and hot water nozzle device. Hot air heater is mainly to melt the snow just landed on the turnout parts, and hot water nozzle snow melting device is to remove the snow plow into the turnout or by the vibration of running vehicles fall from the bottom into the turnout snow and by the storm Into the turnout snow area.
