초록
모노레일 분기장치는 열차의 회차를 위해 110톤 중량의 모노레일 궤도빔 전체를 움직여 진로를 구성하는 장치로 도시철도의 선로전환기와 같은 역할을 수행한다. 도시철도의 선로전환기는 고장 발생 시 유지보수자에 의해 수 분내에 수동전환이 가능하고 해당 진로를 구성하여 열차를 소통시킬 수 있지만 모노레일 분기장치는 고장 발생 시 수동전환 개시 후 1회 전환하는데 평균 50분의 시간이 소요되기에 본선 영업 운행 중지와 같은 심각한 문제를 초래한다. 이에 모노레일 분기장치에 비상전환장치를 별도로 설치하고 수동전환 평균시간 56초에 동작이 가능한 비상전환장치를 통해 분기장치 고장시 열차운행지연을 예방할 수 있었다.
Abstract
The monorail track-switch is a device that configures a path by moving the entire 110 ton weight monorail track-beam for the rotation of trains, and serves as a point-machine for urban railways. In the event of an unusual situation, the point-machine can be manually switched within minutes by the maintenance worker and the train can be carried out by forming the route, but the track-switch takes an average of 50 minutes to switch manually, causing serious problems such as suspension of operation. As a result, the emergency switching device was installed separately on the monorail Track Switch and the emergency switching device, which can be switched in an average manual switching time of 56 seconds during manual switching, was able to prevent train operation delays in case of a Track Switch failure.
