Description

[Detailed description of the invention] In the present invention, in the coke oven working machine 1, the supporting frames 4, 4 of the oven cover removing device 2 and the oven cover frame cleaning device 3 are integrated with each other by sandwiching the coke extrusion beam 5 or the coke guide grid. This invention relates to a furnace lid removing and furnace lid frame cleaning device that is formed and configured to be movable back and forth simultaneously along the furnace chamber center line a.

That is, the upper ends of both support frames 4.4 are integrally formed in a portal shape with a connecting rod 8 perpendicular to the center line a of the furnace chamber (see FIG. 5), and the upper ends of the support frames 4.4 are formed integrally in the shape of a portal. The tip of the horizontal U-shaped frame 6 is connected to the center of the rear end of the U-shaped frame 6, and the driving cylinder 7 provided in the coke oven working machine 1 is connected to the center of the rear end of the U-shaped frame 6.

Further, at the lower ends of both support frames 4, 4, there is a shaft support 10 for one wheel 9, respectively, and a short track 11, which is laid parallel to the furnace chamber center line a.
11 supports the same wheel 9.

In addition, a fall prevention roller 12° 12 is provided at the U-shaped rear end of the horizontal U-shaped frame 6, and a downward horizontal rail 1 provided on the work equipment 1 side
The same roller 12.12 is supported on the lower surface of 3°13.

The furnace lid removing device 2 and the furnace lid frame cleaning device 3 are provided with vertical wheels 14,1.
5, and the rotation is controlled by actuators 16 and 17 provided on the support frames 4 and 4, respectively.
It is possible to rotate it 90 degrees from the solid line position to the imaginary line position in FIGS.

In addition, what is indicated by 18 in the figure is a sliding guide roller of the horizontal U-shaped frame 6 that is in contact with the side surface of the downward horizontal rail 13.
19 is an extrusion ram provided at the tip of the coke extrusion beam 5;
20 is a furnace chamber, 21 is a furnace lid, 22 is a furnace lid lifting fitting, and 23 is a scraper for cleaning the furnace lid frame.

Therefore, in a state where the coke extrusion beam 5 or the coke guide grid is retracted along the center line a of the furnace chamber, the furnace lid removing device 2 is rotated 90 degrees from the solid line position in FIG. The support frames 4, 4 are moved forward toward the furnace chamber 20 by operating the
After supporting the furnace lid removing device 2, the device 2 is moved back by the cylinder 7, and the device 2 is moved to the solid line position 90 in Fig. 1.
° Rotate and stop.

Next, as shown in FIG. 2, the furnace lid frame cleaning device 3 is rotated 90' from the solid line position in FIG.
3 to the furnace lid frame 24 at the opening of the furnace chamber and move it up and down to open the frame 24.
After cleaning the support frames 4 and 4, operate the cylinder 7 described in 1.
At the same time, the device 3 is moved backward and further rotated to the solid line position in FIG. 2 and stopped.

Thereafter, the coke extrusion beam 5 is moved along the center line a into the furnace chamber 2.
0, and the coke cake in the furnace chamber 20 is guided to the fire extinguishing vehicle through the coke guide grid of the guide vehicle (working machine) stopped at the exit of the furnace chamber 20.

Thereafter, the coke guide grid or extrusion beam 5 is retreated to the position shown by the imaginary line in Figure 1, and the furnace cover removing device 2, which is located at the position shown by the solid line in Figure 1, is rotated by 90 degrees to the position shown by the imaginary line in the same figure, and at the same time, the cylinder 7 is operated. The support frames 4, 4 are advanced to fit the furnace lid 21 supported by the lifting fittings 22 into the furnace chamber 20, and the furnace chamber 20 is dynamically closed using bolts, etc., and then the cylinder 7 is operated to close the furnace chamber 20. At the same time as the device 2 is moved backward, it is rotated 90 degrees from the imaginary line position in FIG. 1 to the solid line position in the same figure.

Conventionally, furnace lid removal and furnace lid frame cleaning devices were each supported independently on a movable trolley, which made inspection and maintenance difficult due to the large number of parts, long operation times, and the strength and size of the movable trolleys. As a result, the gap between the pivot shafts of the furnace lid removing and furnace lid frame cleaning devices is large, and the arm holding the device is long, making it difficult to prevent tilting due to bending.

Since the present invention is constructed as described above, the lower end traveling devices of the support frames 4, 4 of the furnace lid removing and furnace lid frame cleaning devices 2, 3 can be significantly downsized, and the support shafts 14, 15 of the devices 2, 3 can be significantly reduced in size. The spacing can be reduced and the support arms 2' and 3' of the devices 2 and 3 can be shortened, preventing the devices 2 and 3 from tilting due to their weight when removing the furnace lid and cleaning the furnace lid frame, and reducing the number of parts. Since there is less friction and inspection and maintenance are easy, stable operation can be maintained over a long period of time.

Further, since the required operating time can be shortened, there is a practical benefit that can correspond to the shortening of the time cycle of the operation of the coke oven.
