The present invention relates to a hydraulic track switcher and a hydraulic oil filtering method thereof. The hydraulic track switcher includes: an operation unit which moves the position of a tongue rail to change the track of a train vehicle; a driving unit which presses and supplies the hydraulic oil at a predetermined pressure to drive the operation unit; and a filtering unit which filters impurities included in the hydraulic oil being supplied to the operation unit from the driving unit. The filtering unit includes a first filter unit and a second filter unit, respectively, being installed to a first supply line and a second supply line supplying the hydraulic oil to both sides in order to drive at least one cylinder, which is arranged on the driving unit of the operation unit from a gear pump of the driving unit, as a normal state or reverse state. Accordingly, the filter unit can filter the impurities included in the hydraulic oil driving the cylinder and prevent the operation malfunction of the hydraulic track switcher caused by hydraulic oil contamination.

    유압식 선로전환기 및 그의 작동유 여과방법에 관한 것으로, 철도 차량의 진로를 변경하도록 텅 레일의 위치를 이동시키는 작동부, 상기 작동유를 미리 설정된 압력으로 가압해서 공급하여 상기 작동부를 구동하는 구동부, 상기 구동부에서 작동부로 공급되는 작동유에 포함된 오염물질을 여과하는 여과부를 포함하고, 상기 여과부는 상기 구동부의 기어펌프에서 작동부에 마련된 적어도 하나 이상의 실린더를 정위 상태 또는 반위 상태로 구동하도록 상기 실린더 양측에 작동유를 공급하는 제1 및 제2 공급라인에 각각 설치되는 제1 및 제2 여과유닛을 포함하는 구성을 마련하여, 실린더를 작동시키는 작동유에 포함된 오염물질을 여과하여 작동유의 오염으로 인한 유압식 선로변환기의 작동불량을 방지할 수 있다는 효과가 얻어진다.
