課題がある。The former, however, has a problem that when the door frame is bent, a part of each scraper does not come into close contact with the cleaning surface, and the scraping is performed between the scrapers by the divided cleaning by the multistage scrapers. In addition to the problem of leaving residue,
Since the scrapers are arranged in multiple stages vertically, there is a problem that it is not easy to inspect and replace these scrapers. On the other hand, in the latter, the vertical movement cylinder faces the furnace opening of the coke oven without a heat shield, so hot air from inside the oven,
There is a risk of oil burns and burnout due to radiant heat.If even a slight confrontation error occurs in the convex frame with respect to the furnace opening, there is a risk of collision with the furnace opening when the first half frame enters the furnace opening, resulting in mutual damage. However, there is a problem that the scraper on the other side does not come into close contact with the inner surface of the door frame when approaching to one side.

のである。SUMMARY OF THE INVENTION According to the present invention, an up-and-down moving body is attached to a vertically long pillar having a horizontal cross section so that the up-and-down moving body moves up and down. A lower horizontal axis is provided, and it is elastically opened and closed by two upper and lower sheet surface scrapers and tension springs so as to rotate vertically and horizontally on the lower horizontal axis, and a circular curved surface for guiding the entrance into the furnace mouth is attached to the outside of the tip. It is intended to solve such a problem by arranging two left and right inner surface scrapers formed as described above so as to be rotatable.

密接して掃除することとなる。[Operation] By advancing and advancing the vertically long strut against the door frame, the inner surface scraper is allowed to enter the door frame and the tension spring is tensioned while buffering the circular curved surface for guiding the entrance provided on the inner surface scraper in the furnace opening. The inner scraper is brought into close contact with the inner surfaces of both sides of the door frame, and the seat scraper is brought into close contact with the seat surface elastically to vertically move the vertical moving body. The upper and lower two sheet surface scrapers move up and down while closely following the sheet surface to clean the entire length, so that cleaning is perfect and no cleaning residue is generated. In addition, the two left and right inner scrapers move horizontally on the lower horizontal axis as well as horizontal swivel, so that even if there is an error during facing, it surely enters the furnace mouth and tension of the tension spring tightens the door frame. The inner surfaces of both sides will be cleaned closely.
