An extractor for removing and mounting the oven door is used for extruding the red coke in the coke oven for producing steel coke.

1 shows a structural diagram of a coupling portion of a conventional extractor and a door for operating a coke oven door.

As referred to herein, the oven door 110 of the coke oven is composed of a door vertical frame 111 and a lifting bar 102 installed above and below the door vertical frame, and the extractor 100 is connected to the lifting bar. The upper and lower hook hooks 101-1 and 101 to be coupled and separated, and a lifting cylinder 103 and a lifting guide roller 104 for moving the upper and lower hook hooks in the vertical direction.

However, when the center 100 (verticality) of the door is shifted due to thermal expansion or contraction of the oven door 110 during the course manufacturing process, when the extractor 100 is advanced to detach the oven door, the upper and lower parts of the extractor are moved. There is a risk of equipment damage or safety accidents by forcibly extending the door in a state where the coupling becomes unstable or inadequate detachment between the hook hangers 101-1 and 101 and the lifting bar 102 in the vertical frame on the door side. Can be.

That is, when the oven door 110 is detached in a state where the vertical centers of the upper hook hangers 101-1 and the lower hook hangers 101 do not coincide with each other by repetitive operation of the extractor 100, they are biased to one side. The hook bar 101 is lifted in the state so that the lifting bar 103 is inserted in a spaced state, and when it is forcibly croined in this state, the vertical center is deformed due to the strong impact of the extractor. .

Deformation of the vertical center leads to a detachment phenomenon of the oven door 110, resulting in a delay, and also poor centering of the door cleaner, so that tar (TAR) is adhesively fixed to the sealing strip of the door (110).

Accumulated settling of tars presents another door mounting failure causing gas leakage, which in turn causes environmental pollution.
