Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a cutting straightening device for the front surface of a leveling port of a coke oven door.

<Prior art> The leveling opening of the coke oven door is prepared for coke kiln formation with a small lid after the charging coal is leveled, but carbon and tar generated during coke oven formation adhere to it and prevent it from being reused after opening. When the lid is closed, a gap is formed due to accretion, causing gas leakage, so it is necessary to clean the lid together with the lid when opening. Conventionally, techniques such as those disclosed in Japanese Patent Publication No. 59-32510 have been used to clean the leveling opening and the small lid when opening to avoid this problem.

In the above-mentioned publication, a horizontal frame is provided on the extruder, a horizontally long frame that moves forward and backward in the front and rear directions is provided on the horizontal frame, a cart that moves in the horizontal direction is placed on the horizontally long frame, and vertical and vertical frames are provided on the cart. A device connected to the pressure supply pipe is attached to the moving mechanism so as to move up and down, and a pressure water injection nozzle is provided at the front end of the device, and the water injection nozzle is installed on the front end surface of the leveling opening of the door and the small lid. It states that the knife should be cleaned by circling it directly around the knife edge and its surrounding area.

<Problems to be Solved by the Invention> However, the structure and operation of this publication are extremely complicated, and in addition, the pressure water is emitted in a very thin line in order to increase its effectiveness, so there is no cleaning residue between the emitted pressure water. There is a problem in that the front surface of the leveling opening cannot be cleaned evenly.

<Means for Solving the Problems> The present invention is characterized in that a horizontal support is attached to the upper end of a vertical column provided so as to run on the working floor of an extruder, and the horizontal support is capable of freely adjusting forward and backward movement and vertical movement. A rectangular frame-shaped machine with fixing legs on the front is hung from the machine, and a rotating machine rotates around the front of the leveling hole using vertical and horizontal screw shafts on the front of the machine to cut and straighten the machine flatly. A cutter is attached thereto, and a parallelizing device with legs for making the body parallel to the front surface of the leveling hole when moving forward is removably fitted to the shaft of the rotary cutter.

<Function> The present invention allows the four legs of the parallel tool to open the leveling port by freeing the fixing legs and fitting the parallel tool and adjusting the vertical movement of the machine when the leveling port is opened. At the point where the machine body is parallel to the front end surface of the leveling port by contacting the front end surface, place the fixing leg in contact with the backstay of the coke oven and tighten the screws, then remove the parallel device, and While rotating the rotary cutter that is in contact with the front end, the vertical and horizontal screw shafts are rotated in forward and reverse directions to rotate the front end of the leveling mouth to cut and straighten the protruding portion.

<Example> Examples will be described below based on the drawings.

A vertical shaft 3 that is supported by a swing bearing 2 and rotates is installed on a working floor 1 provided in an extruder running on the extrusion side of a coke oven, and a horizontal support 3a is provided from the upper end of the vertical shaft 3, A pulley 4 is fitted to the support bone 3a so that it can move forward and backward within the horizontal support bone 3a, and the chain 5 is lowered so that it can be adjusted in and out from the pulley 4.
A rectangular frame-shaped body 6 is suspended and attached to the chain 5. The body 6 is much larger than the leveling port 19, and a total of four fixing legs 15 are attached to the top and bottom of the front side of the side plate facing forward. 1
5a is a magnet provided on the front surface of each leg. 16a,
16b is a tightening nut for the leg 15.

A vertical screw shaft 7 is installed inside the side panels of the fuselage 6.
a, 7b are attached, and both ends are screwed onto the screw shafts 7a, 7b, and a horizontal screw shaft 8a is attached. Note that 8b is a connecting shaft, and 9 and 10 are motors with reduction gears for rotating the screw shafts in forward and reverse directions.

A carrier box 12 is screwed onto the horizontal screw shaft 8a, and a shaft 13 protrudes from the front surface of the box 12.
A rotary cutter 11 is attached to the tip of the cutter 11 facing forward. 17 is the leg 17a facing forward from the front of the four corners.
18 is a groove for attaching and detaching provided in the middle of the instrument in the lateral direction. In addition, 19a is the front end surface of the leveling mouth, 20 is a small lid for opening and closing the leveling mouth, 21 is a knife edge, 22 is an arm for opening and closing the small lid, 23 is a handle for adjusting the entrance and exit of the rotary cutter 11, and 24 is a back stay. be.

As a result of the above, when the front end surface 19a of the leveling port 19 is uneven and requires cutting correction, when opening by removing the small lid 20, turn the vertical shaft 3 and move the horizontal support 3a in the direction of the leveling port 19. The pulley 4 is run toward the target to move the aircraft 6 forward. Chain 5 if necessary
The vertical movement of the body 6 is adjusted by unwinding it.

At this time, rotate the rotary cutter 11 to the horizontal screw shaft 8a.
By this operation, the screw is positioned on the center of the screw shaft, and the parallel tool 17a is fitted onto the shaft 13 facing forward, and the tightening nuts 16a and 16b are loosened to leave the leg 15 free.

When the fuselage 6 moves forward, the four legs 17a of the instrument 17
hits the front end surface 19a of the leveling port and aligns the body 6 parallel to the slope of the leveling port 19, so check that each fixing leg 15 is magnetically attached to the back stay 24 before tightening the nuts 16a, 16b. Tighten to fix the machine body 6 and remove the rear instrument 17.

FIG. 1 shows a state in which the body 6 is fixed and the instrument 17 is removed. Next, the vertical and horizontal screw shafts 7
Operate a, 7b, and 8a to reach carrier box 12.
If necessary, move the rotary cutter 11 to the position shown by the solid line in Figure 5.
3 to make contact with the front end surface 19a of the leveling mouth, then operate the motors 9, 10, 14 to rotate the rotary cutter 11 while rotating the vertical screw shafts 7a,
7b and the horizontal screw shaft 8a are rotated in the forward and reverse directions along the front end surface 19a, and the protruding portion produced on the front end surface 19a is cut off and flattened.

The operation of the motors 9 and 10 is automatically controlled by pulse signals or the like so that they rotate around the rotary cutter 11.

<Effects of the Invention> As described above, the present invention allows the machine to move forward by attaching a removable parallel device to the shaft of the rotary cutter, so that the leveling spout and the coke oven are tilted differently. This also produces the effect that the body can be fixed by making the circumferential parallel of the rotary cutter parallel to the front end surface of the leveling port. Occasionally, when the front end of the leveling hole is cut and straightened in the same parallel manner by rotating the rotary cutter, the knife edge may come into close contact with the front end of the leveling hole when the leveling hole is re-closed with the small lid. This has the effect of preventing gas leakage.
