Disclosed is a width-variable vehicle for a railway track. The width-variable vehicle for the railway track according to the present invention includes: driving units in both sides where track wheels joined to the railway track and operated are mounted; a main frame arranged between the driving units in both sides and having an upper part where an excavator is mounted; multiple bridges folded while connecting both sides of the main frame and the driving units in both sides and adhering to a lateral surface of the main frame or separated from the lateral surface of the main frame; a foldable operating unit inducing the multiple bridges to be folded, and composed of a hydraulic cylinder joined to the inside of the main frame and having a cylinder rod taken into or taken out from the inside of the main frame by a power supply, an operating member joined to one end of the cylinder rod, joined to the inside of the main frame, and moving forward and backward in a longitudinal direction, and a folding induction member of which one end is hinge-joined to both sides of the operating member and the other end is hinge-joined to both bridges; multiple auxiliary wheel units formed in the lower side of the multiple brides and operated in a direction perpendicular to the track wheels; a lifting unit lifting the multiple auxiliary wheel units to be seated on the track wheels or separated from the track wheels; and an auxiliary rail arranged to be perpendicular to the railway track and where the auxiliary wheel units are seated.

    차폭 가변형 철도 궤도 작업차가 개시된다. 본 발명에 따른 차폭 가변형 철도 궤도 작업차는, 철도 궤도에 결합되어 주행되는 궤도바퀴가 장착되는 양측의 주행부; 상기 양측의 주행부 사이에 배치되며, 상부에는 굴삭기가 장착되는 메인프레임; 상기 메인프레임의 양측과 양측 주행부를 연결하며 절첩작동되면서 메인프레임의 측면에 밀착되거나 이격되는 복수의 브릿지; 상기 메인프레임의 내부에 결합되며, 동력공급에 의해 인출 또는 인입작동되는 실린더로드가 구비된 유압실린더와, 상기 실린더로드의 일단에 결합되고 메인프레임의 내부에 결합되어 길이방향으로 전후진되는 작동부재와, 상기 작동부재의 양측에 일단이 힌지 결합되고 타단은 양측 브릿지에 각기 힌지결합되는 절첩유도부재로 구성되어 브릿지의 절첩작동을 유발하는 절첩구동부; 상기 복수의 브릿지의 하부에 형성되며 궤도바퀴와 직교되는 방향으로 구동되는 복수의 보조바퀴부; 상기 복수의 보조바퀴부를 승강작동시켜 궤도바퀴에 안착되거나 분리되도록 하는 승강구동부; 상기 철도 궤도에 직각되게 배치되며 상기 보조바퀴부가 안착되는 보조레일을 포함하여 구성된다.
