A LIFTING JACK AND BRIDGE UPPER STRUCTURE LIFTING METHOD USING THE SAME
A hydraulic lifting jack for lifting an upper structure of a bridge is disclosed. The hydraulic lifting jack comprises: a cylinder unit supported by a lower structure of a bridge to provide hydraulic pressure; a cylinder cap fixated and coupled to an upper portion of the cylinder unit; a piston unit inserted into the cylinder unit and the cylinder cap to be lifted by hydraulic pressure; a ram screw unit fastened to an upper portion of the piston unit to lift the upper structure of the bridge; and a height control unit installed between the cylinder unit and the cylinder cap to enable the upper structure of the bridge to be lifted at a preset lifting height.
교량 상부구조물을 인상하기 위한 인상용 유압잭이 개시된다. 인상용 유압잭은, 교량 하부구조물에 지지되어 유압이 제공되는 실린더부; 실린더부의 상부에 고정 결합되는 실린더 캡; 실린더부 및 실린더 캡에 삽입되어 유압에 의해 승강하는 피스톤부; 피스톤부의 상부에 체결되어 상기 교량 상부구조물을 인상하는 램스크르부; 및 교량 상부구조물이 미리 설정된 상승높이만큼 인상되도록 실린더부와 실린더 캡의 사이에 설치되는 높이조절부;를 포함한다.
