Abstract PURPOSE: An apparatus for maintaining the ascent state of upper rolls of a hot leveling machine is provided which is capable of maintaining the ascent state of the upper rolls using safety pin and props when ascending the upper rolls to maintain and repair upper and lower rolls of the hot leveling machine. CONSTITUTION: In an apparatus for maintaining the ascent state of upper rolls by ascending an upper roll support frame(120) for supporting the upper rolls(110) of a hot leveling machine, inserting a pin into pin inserting holes formed on the upper roll support frame(120) and supporters(102,122) of a main body(100) of the hot leveling machine and positioning props(50) at certain positions between the upper rolls(110) and lower rolls(140), the apparatus for maintaining the ascent state of the upper rolls of the hot leveling machine is characterized in that extension elements having floodlight holes(12,22) are formed on the supporters(102,122), an optical sensor is installed to sense whether the center of the floodlight holes(12,22) is corresponded or not, a pin(130) is mounted on the supporters(102,122) so that the pin(130) is inserted into the pin inserting holes of the supporters(102,122), and the props(50) are moved between the upper and lower rolls(110,140) by cylinders(80) installed at one side of the main body(100). 본 발명은 열간교정기의 상부롤 상승상태 유지장치에 관한 것으로서, 열간교정기의 상부롤(110)을 지지하는 상부롤 지지프레임(120)을 상승시키고 상기 상부롤 지지프레임(120)과 열간교정기 본체(100)의 지지대(102)(122)에 형성된 핀삽입구멍에 핀을 끼우고 상부롤(110)과 하부롤(140) 사이의 소정위치에 고임대(50)를 위치시켜 상부롤 상승상태를 유지시키기 위한 장치에 있어서, 상기 지지대(102)(122)에 투광홀(12)(22)을 갖는 연장편(10)(20)에 형성되고, 상기 투광홀(12)(22)의 중심이 일치되는지의 여부를 감지하기 위한 광센서가 설치되며, 상기 핀(130)은 상기 본체(100)의 일측에 설치된 실린더(44)에 의해 상기 지지대(102)(122)의 핀삽입구멍으로 끼워지게 장착되며, 상기 고임대(50)는 상기 본체(100)의 일측에 설치된 실린더(80)에 의해 상기 상부롤(110)과 하부롤(140) 사이로 이동되게 구성되어, 열간교정기의 상, 하부롤들을 유지 및 보수하기 위해 상부롤을 상승시켰을 때 이 상부롤의 상승상태를 안전핀과 고임대로 유지시킬 수 있는 효과를 갖는다.
