Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door frame cleaner for a coke oven, and more particularly to a door frame cleaner that moves by a scraper even if there is a facing error between the door frame cleaner and the door frame. The present invention relates to a door frame cleaner that is easy to inspect and replace for close cleaning.

[0002]

2. Description of the Related Art As a door frame cleaner of this type, there are JP-A-50-51503 and JP-A-52-63902.

The former describes that the inner surface and the seat surface scrapers are arranged in multiple steps on a vertically moving support frame, and the vertical movement of the support frame causes each scraper to share the cleaning of the inner surface and the seat surface of the door frame. is doing.

The latter is provided with two upper and lower convex frames which move up and down along a supporting frame by a cylinder mechanism, and spring-loaded sheet surface scrapers are provided on both front surfaces of the latter half frame of the convex frame to enter the furnace opening. It is described that the first half frame is provided with an internal scraper that is pushed out to the side.

[0005]

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.

[0006]

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.

[0007]

[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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the drawings.

A vertically long support 1 formed by a lateral cross section is supported by a support member 2, and a vertically movable body 3 is fitted and attached to the vertically long support 1 so as to move vertically. 4 is a motor for vertical movement, 5
Is a power transmission chain, 6a is an upper drive wheel, 6b is a lower floating wheel, 7 is an endless chain that is wound between upper and lower wheels, and 8 is a chain tension spring.

The vertical moving body 3 has rollers 9a and 9b at the upper and lower portions, and the rollers 9a and 9b are meshed with the endless chain 7, and the rotation of the chain 7 causes the vertical movement between the upper and lower wheels.

The vertical moving body 3 is a mounting shaft for the upper and lower rollers 9a and 9b.
Both ends of 9c and 9d are projected to the outside of the vertically long support 1, and the mounting shaft 9
Side plates 10a and 10b are mounted so as to project from the both ends of c and 9d toward the front surface of the vertically long strut 1, and the side plates 10a and 10b are mounted on the front surface of the vertically long strut 1 with a slight parallel interval between them and the substrate 11 is attached. Upper horizontal shaft 12a between the front upper parts of the side plates 10a, 10b
Is provided horizontally, and the suspension levers 14a and 14b having two front and rear halves that are pivotally hung to move laterally by suspending the pivot 13 are provided on both sides of the upper horizontal shaft 12a, and the lower ends of the suspension levers 14a and 14b are attached to the substrate 11. The lower half to be attached is pressed forward and backward by a leaf spring 15 that is curved and bulged, and the lower horizontal shaft 12b is suspended horizontally between the lower ends of the suspension levers 14a and 14b by means of a pivot 13 and the lower horizontal shaft 12b. Is designed to move back and forth and left and right based on the upper horizontal axis 12a. This lower horizontal axis 12
The base ends of the V-shaped arms 16a and 16b, which project diagonally upward and diagonally downward, are attached to the center portion of b so as to be rotatable up and down, and are fitted in the cylinder 17 so as to be fitted into the concave portions at the tips of the V-shaped arms 16a and 16b. The horizontally elongated seat surface scrapers 18a and 18b are fitted so that the central portions of the scrapers 18a and 18b rotate in a small horizontal direction, and the shaft 19 is fixed. Reference numeral 20 is a push spring having a stop point on the substrate 11 so as to contact the lower surface of the V-shaped arm 16b to vertically rotate the V-shaped arms 16a and 16b. Again 21
a and 21b are stoppers for preventing the vertical movement of the seat surface scraper.

The lower horizontal shaft 12b is a shaft for horizontally rotating the inner scrapers 22a, 22b forward from the center.
A tension spring 24 is attached between the inner surface scrapers 22a and 22b and is elastically opened and closed. Numerals 25a and 25b are circular curved surfaces for guiding the entrance provided on the outer sides of the front portions of the inner surface scrapers 22a and 22b, and 26a and 26b are leaf springs for turning control.

When the door of the coke oven is removed and the door frame 27 is exposed, the vertical support 1 supported by the support member 2 is made to face the door frame 27 and is moved forward. As the inner surface scrapers 22a, 22b move forward, the circular curved surfaces 25a, 25b for guiding cushion the entrance portion of the door frame 27 and enter the door frame 27 while compressing the tension spring 24. The inner surface scrapers 22a and 22b come into close contact with the inner surfaces 27a and 27b of the door frame 27. There are 2 seat scrapers 18a and 18b.
The springs 15 and 20 of the pair elastically come into close contact with the seat surfaces 27c and 27d.

When the motor 4 is operated to rotate the endless chain 7 to move the vertical moving body 3 up and down, the seat surface scraper and the inner surface scraper move up and down while closely contacting the seat surface and the inner surface of the door frame. The seat surface and the inner surface of will be thoroughly cleaned.

At this time, even if a facing error occurs between the inner scrapers 22a and 22b and the door frame 27, the lower horizontal axis
The inner scrapers 22a and 22b move laterally in a direction to absorb the error due to the lateral movement of 12b and the horizontal swiveling mechanism of the inner scraper. Is prevented, and even if the seat surface has irregularities due to warping, etc., the sheet surface scrapers 18a and 18b move forward and backward, left and right, and horizontally rotate to follow the irregularities, so no spots for cleaning are created. It will be.

[0016]

As described above, according to the present invention, the total length of the seat surface and the inner surface of the door frame is made elastic by the upper and lower two sheet surface scrapers and the two inner surface scrapers provided on the single vertical moving body. Since the cleaning is performed in close contact with each other, there is an effect that a cleaning omission and a cleaning residue are not generated.

Moreover, since the seat surface scraper and the inner surface scraper have a lower horizontal shaft that moves back and forth and left and right based on the upper horizontal shaft, and a means for turning and the like, when the vertically long pillar directly faces the door frame, a normal operation by remote operation is performed. Even if there is an error, or even if the door frame is warped, the inner scraper smoothly enters the furnace opening, and the seat surface scraper is in close contact with the seat surface to prevent mutual damage. Produces the effect of cleaning.

Since the vertically long pillars are formed in a cross section,
The motor and drive mechanism can be prevented from being oiled and burned out by acting as a heat insulating plate, and both sides are open, and the number of seat surface and inner surface scrapers is as small as two so that the drive mechanism and scraper are The effect is that inspection and replacement can be easily performed.
