[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door cleaner for removing tar and coke adhering to a door of a coke oven.

[0002]

2. Description of the Related Art Conventionally, as this type of apparatus, there has been known an apparatus which removes deposits by using a cutter to remove deposits by injecting high-pressure water, compressed air, or powder. Also known are a high-pressure water injection nozzle supported by a rocking elastic device, a device using a high-pressure nozzle with a rocking elastic device, a nozzle supported so as to avoid refraction, and the removal of deposits by a scraper with a rockable arm.

No. 6885, JP-A-59-68388, JP-A-63-50885, JP-A-62-44045 and JP-A-60-93745.

[0003] In many cases, cutters, high-pressure water, nozzles and the like are used independently. Some of these devices are used in combination, but the characteristics of each device are not sufficiently exhibited. In the case of using the washing nozzle, since it is necessary to spray the entire area of the door from the washing nozzle to the place where tar and coke are adhered, a swinging device for the washing nozzle is provided. In this case, the size of the apparatus was increased, which hindered the space. The prior art generally does not include a means for adjusting the position of the door cleaner with respect to the inclination of the door holding device of the door pick-up device mounted on the inner bogie.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to avoid the difficulty of positioning between a door and a door cleaner to remove deposits on a coke oven door and the inconsistency of the inclination angle of the door cleaner with respect to the door. The task is to create a door cleaner.

[0005]

The object of the present invention is solved by the structure described in claim 1 of the utility model registration.

[0006]

[Function] A rail 10 is laid on a guide car frame 3 and an inner trolley 1 runs on the rail 10 and a door cleaner trolley 2 is put on an upper rail 10. The door cleaner frame 4 is pivotally supported by the pin cleaner 9 on the door cleaner truck 2, and a spring 5 is inserted between the guide car frame 3 and the door cleaner truck 2 at the upper and lower portions. Since the inner bogie support 6 is planted in the lower part, even if the holding position of the door 11 of the door removing device provided on the inner bogie 1 is inclined, the inclination of the door cleaner is changed to the door 1.
The distance between the door 11 and the door cleaner frame 4 can be adjusted by an interval adjusting device 7 provided at the end so as to be parallel to and equidistant from 1. As a result, when the inner trolley 1 approaches the door cleaner trolley 2 and pushes the door cleaner trolley 2, the door cleaner frame 4 is elastically fixed by the spring 5, and as a result, the door cleaner is washed with water during operation by the door cleaner. It is possible to remove deposits while the tip of the nozzle 12 and the cutter 13 move parallel to the seal plate 14 and the knife edge 15 of the door 11 while maintaining an equal interval. Inner trolley 1
When the door retracts to a position where it does not contact the door cleaner truck 2, the door cleaner frame 4 is urged toward the inner truck 1 by the upper and lower springs 5 to occupy a certain position. The length of the spring 5 is long enough to cover the distance of the inner bogie 1 after the guide car is stopped and the inner bogie 1 is finely adjusted by centering the door 11 of the coke oven. After adjusting the distance adjusting device 7 in advance, the inner carriage 1
After the contact with the door 2, the amount of pressing the door cleaner frame 4 against the guide car frame 3 is always constant.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Configuration According to FIGS. 1 to 3, a rail 10 is laid on an upper guide vehicle frame 3 and an inner bogie 1 runs. The door cleaner cart 2 is further mounted on the rail 10. The door cleaner frame 4 is pivotally suspended from the door cleaner cart 2 via the pin joint 9. When the inner cart 1 approaches the door cleaner cart 2, the inner cart 1 pushes the door cleaner cart 2 via the inner cart support 6, and the door cleaner cart 2 is pressed against the guide car frame 3 via the spring 5. . An inner bogie support 6 is fixed to a lower portion of the inner bogie 1 and extends from the lower portion to a lower portion of the door cleaner frame 4, and a point thereof abuts toward a lower portion of the door cleaner frame 4. Spacing adjustment device 7 at the tip of inner bogie support 6
Is provided. The inclination of the support state of the door 11 is adjusted by adjusting the interval adjusting device 7 which is a liner so that the interval between the door 11 and the door cleaner frame 4 becomes parallel. Remove the deposits with the cutter 13 on the side of the door.
And a door cleaner unit comprising a washing nozzle 12 is driven up and down by a chain 17 and the like, and the washing nozzle 12
This is carried out by swinging the coke oven door 11 in the lateral direction by means of FIG. 8 (FIG. 1). The washing nozzle 12 is moved laterally with respect to the upper surface of the door by a lateral feeding device 16 such as a hydraulic cylinder. The washing nozzle 12 is vertically swung with respect to the door 11 to perform washing (FIG. 4). The unit including the cutter 13 and the washing nozzle 12 is laterally moved by a traverse device 16 such as a hydraulic cylinder with respect to the lower surface of the door. The water washing nozzle 12 is vertically swung with respect to the door 11 to wash the water. The lower surface of the door is not shown,
A device similar to that of FIG. 4 is also provided on the lower surface of the door. According to the present invention, according to the present invention, the swinging device, which used to be large and required a large space due to the use of levers and links, swings the output shaft by a combination of a cam and a turret with a cam contact. It is compact because it uses a roller-gacam mechanism that changes to motion. After the attached tar and coke is removed, the door 11 is separated from the door cleaner by running the inner carriage, while the door cleaner carriage 2 is released from the pressing force of the spring 5 and returns to the set position of the spring 5.

Operation When the inner trolley 1 is kept away from the door cleaner trolley 2, the action of the spring 5 causes the door trolley 2 to move.
Is positioned at a predetermined position on the left side in FIG. The inner trolley 1 is brought closer to the door cleaner trolley 2, whereby the inner trolley 1 pushes the door cleaner trolley 2 and presses against the guide car frame 3. Spring 5
Is compressed and the door cleaner frame 4 pivotally supported by the pin 9 on the door cleaner truck 2
Is positioned at a fixed position with respect to the coke oven door 11 via the coke oven. Since the inclination of the door 11 changes depending on the holding state of the door removing device, the hanging angle of the door cleaner frame 4 is changed by the interval adjusting device 7 in accordance with the angle of the door 11. Thereby, the cutter 1 for the door 11
3. The interval between the washing nozzles 12 is always kept at a predetermined value.

[0009]

According to the present invention, since the spring is provided, when the inner bogie 1 does not approach the door cleaner frame 4, it is always returned to a predetermined position on the left side in FIG. ing. Therefore, the movement amount and the force for pressing the door cleaner truck 2 after the inner truck 1 contacts the door cleaner truck 2 are always unchanged. Door cleaner frame 4 supported by pin joint 9
The inner carriage 1 is constantly urged toward the door 11 by the spring 5 when the inner carriage 1 is far from the door cleaner carriage 2. When the inner trolley 1 approaches the door cleaner trolley 2, the inclination of the door cleaner can be easily adjusted according to the inclination of the door by adjusting the liner. The use of the roller gear cam mechanism for the swinging device 8 makes the swinging mechanism compact. As described above, the removal of the deposits on the door becomes reliable and easy.
