포켓 슬라이딩 타입 지하철 출입문의 겨울철 결빙 문제 해결을 위한 대체 매커니즘 고찰

Abstract

We ache all over our body for an abnormal climate every year. It is said that people are getting hotter because of a global warming. Meanwhile, a record-breaking cold wave is annually observed. It is reported that many people use public transportation in winter when it is freezing with a lot of snow. Because a personal car is more risky than that, and but a train is relatively safe and fast so people choose it as a duck takes to water. However, a train could not always be a secure means of transportation since 128 trains ceased an operation by being a frozen entrance in January 5, 2010. And the next day, either 52 trains did not start or abort train service running on a railroad. After that, KORAIL decided to install heat rays so that they melt snow but it was too late to prevent these trains from freezing as if it was mending the barn after the horse is stolen. By the way, I thought that if something prevented snow from coming down a railroad in advance, heat rays would not need to be installed. And I was motivated by thinking how I can prevent. A type of pocket sliding door is used in Korean subway trains’ entrance doors. Such a door has a simple structure and is mostly picked up on low speed subway trains with a resonable price. But although it is structurally closed, there exists a crack between its frame and panel. And a snow piled up and Korean subway trains have a structure having no choice but to be frozen while running an engine. Thus, in order to supersede such a door, I suggest structure mechanism which has a simple organization structure and keeps between its body and panel a better adhere and prevents piled-up snow from freezing.; 지난해 서울 지하철 1~8호선을 이용한 승객은 개통 이래 최다인 24억 3400만여명으로 집계됐다. 하루 평균 이용객은 667만명에 달할 정도이다. 그래서 지하철은 '시민들의 발'이라고도 한다. 특히 겨울철의 춥고 눈오는 날에는 더욱 많은 사람들이 지하철을 찾게 된다. 하지만 이런 시민들의 발이 얼어붙는다면 어떻게 해야할까? 2010년 1월 5일과 6일에는 수도권 지하철 180대가 출입문 결빙에 의해 운행에 차질을 빚었다. 철도공사에서는 신발에 묻은 눈을 털고 들어오라는 안내 방송외에는 별다른 대책을 세우지 못하였다. 뒤늦게 전동차 출입문에 서리 방지액을 뿌리는 등 비상 방안을 내세웠지만 이미 늦은 대처였다. 철도공사에서는 출입문 바닥 가이드레일에 10도 이상의 온도를 유지할 수 있는 열선을 설치하겠다고 발표했다. 눈이 흘러들어도 열선으로 녹여내서 문이 얼어붙을 틈을 주지 않겠다는 것이다. 하지만 이런식으로 결빙을 막는 것이 매우 비효율적이라고 생각되었다. 아예 문 틈새에 눈이 들어오지 않는다면 일부러 열을 유입할 필요가 없을 것이다. 본 논문에서는 국내의 지하철 출입문은 겨울철에 결빙사고가 일어나는지 분석해보고 해결점을 제안하고자 한다.
