Vehicle lifting device provided on special train for replacing gravel ballast to concrete ballast
The present invention relates to a vehicle body lifting device which is included in a special railway vehicle for replacing a track bed, so as to perform a temporary support so that the vehicle can move forward while maintaining a fixed height from the road surface during replacement of the track bed. The vehicle body lifting device comprises: a horizontal member (100) coupled to the lower part of a special railway vehicle for replacing a track bed, entering a rail of which supporting force is lost, and in which a first guide groove (110) is formed in parallel to the widthwise direction of the vehicle body; a first horizontal boom (200) which is coupled to the first guide groove (110) of the horizontal member (100) in order to slide, and in which a second guide groove (210) is formed along the inner side thereof and a first vertical member (220) is vertically coupled to the end portion extended towards one side of the vehicle body; a second horizontal boom (300) which is coupled to the second guide groove (210) of the first horizontal boom (200) in order to slide, and in which a second vertical member (310) is vertically coupled to the end portion extended towards the other side of the vehicle body; a pair of caterpillar units (400) coupled to the first vertical member (220) and the second vertical member (310), respectively, in order to be lifted, and selectively placed on the road surface; and a pair of linear driving units (500) for pushing and pulling the first horizontal boom (200) and the second horizontal boom (300) in the opposite direction from each other.
본 발명은 도상 교체 시에 차량이 노면에서 일정높이를 유지하면서 전진될 수 있도록 임시로 지지하기 위해 도상 교체용 특수 철도차량에 구비되는 차체 리프팅 장치로서, 지지력이 상실된 레일에 진입하는 도상 교체용 특수 철도차량의 하부에 결합되고, 차체의 폭방향과 나란하게 제1 가이드홈(110)이 형성되는 수평부재(100); 상기 수평부재(100)의 제1 가이드홈(110)에 슬라이딩 가능하게 결합되고, 내부를 따라 제2 가이드홈(210)이 형성되며, 차체의 일측으로 연장된 단부에 제1 수직부재(220)가 수직으로 결합되는 제1 수평붐대(200); 상기 제1 수평붐대(200)의 제2 가이드홈(210)에 슬라이딩 가능하게 결합되고, 차체의 타측으로 연장된 단부에 제2 수직부재(310)가 수직으로 결합되는 제2 수평붐대(300); 상기 제1 수직부재(220) 및 상기 제2 수직부재(310)에 각각 승강 가능하게 결합되어 노면에 선택적으로 놓여지는 한 쌍의 무한궤도부(400); 및 상기 제1 수평붐대(200)와 상기 제2 수평붐대(300)를 서로 반대되게 밀고 당기는 한 쌍의 직선구동부(500);를 포함하는 것을 특징으로 한다.
