Description

[0001] Apparatus for centering scraper of door cleaner [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for centering a scraper of a door cleaner, and more particularly, to an apparatus for centering a scraper of a door cleaner by providing a centering device at upper and lower portions of a vertical cylinder of the door cleaner, To the centering of the scrapers.

The pusher car is extruded using ram and the coke oven is filled with the red coke by the coke guide of the transfer car through the bucket car or the coke guide of the transfer car. Transfer to a quenching car. The cycle time of this process makes it possible to continuously produce coke.

Conventionally, when a door cleaner is used, there is no base position in a top scraper or a bottom scraper so that it operates only in the left or right direction. Since there is no position to set the base position, that is, the center position, bending of the scraper occurs when the cylinder is naturally advanced or slightly advanced.

In addition, since the moving range of the cylinder moves from the left end to the right end of the upper or lower portion of the door, it is removed, so that the equipment load caused by the carbon is also seriously affected, and troubles frequently occur. Poor. As a result, problems such as gas leakage (leakage of gas), poor installation of a door due to carbon, and environmental accidents have occurred, resulting in an increase in production costs of steel products.

A door cleaner scraper centering device according to the present invention is a device for centering a door cleaner scraper to which a door cleaner is attached, comprising: a centering unit 110 as shown in FIGS. 1 and 2; And a guide unit (120).

3 to 6, the centering unit 110 of FIG. 1 is installed at upper and lower portions of a door cleaner scraper, that is, a top scraper 20 and a bottom scraper 30, .

Such a centering unit 110 may be provided in each of the scrapers 20 and 30 so as to be able to flow in accordance with the flow of the scraper and be provided with a protruding portion having a predetermined size such as the centering roller 113 of FIG. . The protruding portion is configured such that the direction is switched by another device, a device, or a pulling rail, and the centering is performed through this structure.

The centering unit 110 is attracted by a guide unit 120 to be described later, and is joined to the guide unit 120.

2, the guide unit 120 contacts the centering unit 110 and is configured to attract the protruding portion of the centering unit 110, for example, the centering roller 112 to the home position.

The guide unit 120 sets a position for centering the centering unit 110 and sets it as a base position so as to attract the centering unit 110. [

1, the centering unit 110 includes a body plate 111; And may include a centering roller 112.

First, the body plate 111 functions as a frame to be fixed, and is fixedly attached to the scrapers 20 and 30.

As shown in FIG. 1, the body plate 111 is preferably in the form of a plate, and its rigidity is preferably a metal material having a rigidity enough to withstand the impact of the guide unit 120 to which it is joined.

The body plate 111 may have a roller shaft 113 protruding from the surface at one end thereof and the centering roller 112 may be provided on the roller shaft 113.

The centering roller 112 may be an idle roller and rolled through contact with other portions to minimize impact absorption and frictional forces.

The centering roller 112 is attracted by the guide unit 120 to be guided to the home position, and the seating at such a home position corresponds to the main object pursued by the present invention.

2, the guide unit 120 includes a base plate 121; A guide arm 122; And a centering hole (124).

3 to 6, the base plate 121 is installed at the rear upper portion and lower portion of the cylinder for vertically driving the door cleaner, and includes a guide arm 122, which will be described later; And a centering hole 124 are provided.
