The present invention relates to a contact detector for a railway switch, which comprises: a power transmission gear in which gears having different diameters are coupled to each other in parallel with respect to one axis; a timing belt pulley coupled with the power transmission gear and having a timing belt hung over a pair of the gears having different diameters; an operation lever in which a cylindrical hole having an upper side portion thereof to be swung about one axis is axially coupled to the power transmission gear or the timing belt pulley, and having a knuckle joint to be coupled to a lower side portion thereof; a knuckle joint for joint-connecting the lower side portion of the operation lever with a rail mounting bracket through a bracket connector; and a sensor for calculating a moving distance of a rail through a gear ratio of the power transmission gear due to a reciprocating motion of the operation lever, and a gear ratio of two timing belt pulleys connected to a timing belt. According to the present invention, a precise measurement can be performed.

    본 발명은 선로전환기용 밀착검지기에 관한 것으로서, 보다 상세하게는 각기 다른 지름의 기어가 일축을 기준으로 나란히 병렬 결합되는 동력 전달 기어; 상기 동력 전달 기어와 결합되고, 타이밍 벨트가 각기 다른 지름의 한쌍의 기어에 걸쳐 있는 타이밍 벨트 풀리; 상측부가 일축을 중심으로 스윙 운동하는 원통홀이 상기 동력 전달 기어 또는 타이밍 벨트 풀리에 축결합되고, 하측부에는 너클 조인트와 결합하는 동작간; 브라켓 연결체를 통해 상기 동작간의 하측부와 레일 취부 브라켓을 조인트 연결시키는 너클 조인트; 동작간의 왕복 동작으로 인한 동력 전달 기어의 기어비와 상기 타이밍 벨트로 연결된 두 타이밍 벨트 풀리의 기어비를 통하여 레일의 이동 거리를 계산하는 센서;를 포함하는 선로전환기용 밀착검지기에 관한 것이다.
