An embodiment will be described below with reference to the drawings.

A horizontal table 4 is provided at a position straddling the neck of the riser 3 on the side of the riser 3 on the furnace top surface 2 of the coke oven 1, and wheels 6a, 6b are mounted on rails 5a, 5b laid on the horizontal stand 4. A gate-shaped cart 7 that runs across the riser 3 is disposed. The vertically long frame 8 is attached to a position outside the center on the portal trolley 7 to form a vertically long traveling body together with the portal trolley 7. A vertical surface 8a is formed on the riser tube 3 side of the vertically long frame body 8, and the rail member 9 is installed vertically. The lower end of the rail member 9 is attached with the universal bearing 10 interposed between the lower end of the rail member 9 and the upper surface of the gate type cart 9. The bearing 10 has a frame 10a mounted on the upper surface of the gate-shaped trolley 7, a first rocker 10b pivotally fixed in the frame 10a, and rockable in both directions perpendicular to both sides of the first rocker 10b. The second rocking member 10c is fixed to the shaft. The upper part of the rail member 9 is guided in the open frontal frame 11 projecting from the vertically long frame body 8, and can move in the left-right direction between the two frame portions 11a and 11b of the U-shaped frame 11. Supported by the first spring receiving members 11c and 11d and the second spring receiving members 11e and 11f movable in the front-rear direction. It can be tilted left and right. Numeral 12 denotes a vertical moving body vertically provided in front of the rail member 9 and comprises an inner cylinder 12a and an outer cylinder 12b which rotate integrally. The upper part of the vertical moving body 12 has rolls 13a, 13b meshed with the ale portion of the rail member 9, and has a shaft 14a, 14 rotatable in the front-rear direction inside a support frame member 13 which moves up and down.
b) The stopped ring 15 and a flange 16 mounted inside the ring 15 outside the outer cylinder of the vertical moving body 12 are supported by being fixed to the shafts 17a and 17b so as to be rotatable in the left-right direction. The rail member 9 has a fastening surface on the front surface of the rail member 9 and is inserted into and supported by a resilient ring 18 which is fixed and protrudes so as to be vertically movable. The elastic ring 18 has a rectangular outer surface elastically supported by an outer ring 18c held between the tips of the fixed overhanging arms 18a and 18b and a spring shaft 18d inward from four diagonal points of the ring 18c. , Consisting of an inner ring 18e having a circular inner surface, and an inner ring 1
The inner surface of 8e is formed by a circular curved surface 18f that bulges out in the middle to make the vertical moving body 12 easily move up and down on the contact surface. Thus, the up-down moving body 12 is supported so as to be tiltable in the front-rear and left-right directions based on the support portion of the upper support frame member 13.

Reference numeral 19 denotes a mounting table provided in the direction of the vertically long frame 8 below the rail member 9. The driving wheel 22 rotates forward and reverse through a motor 20 and a speed reducer 21 installed on the mounting table, and meshes with the wheel 22. By rotating a chain 24 which is stretched between floating wheels 23 mounted on the upper and lower portions of the rail member 9, the support frame member 13 mounted on the chain 24 is vertically moved.

The vertical moving body 12 is rotated by a motor 25 attached to the upper end. The lower end of the inner cylinder 12a is exposed from the outer cylinder 12b, and in this embodiment, a three-piece upper conical cutter 26 and a two-piece lower conical cutter 27 are inserted and mounted. The conical cutter 26 has an upper disk 26a having an outer diameter slightly smaller than the inner diameter of the riser 3, an intermediate disk 26b and a lower disk 26 having a gradually smaller diameter.
Attachment members 26d are attached at alternate positions in the radial direction of c and the outer peripheral portion of each stage of the disk, and a cleaning cutter 26e is attached to the tip of each attachment member 26d. The lower conical cutter 27 has the same configuration as the upper conical cutter except that the upper conical cutter has an upper disc 27a smaller in diameter than the lower disc of the upper conical cutter and a lower disc 27b smaller in diameter than the lower disc. Air is supplied to the inner cylinder 12a of the vertical moving body by an air hose 28, and a part of the supplied air is blown out from a jet port 29 provided between the disks of the upper and lower conical cutters, and each cutter is blown. I'm trying to cool. Further, a part of the supply air is blown out from a blowout port 30 provided at a lower end of the inner cylinder 12a. In the figure, reference numeral 31 denotes an automatic alignment mechanism for stopping the alignment of the gate-shaped cart 7 to the ascending pipe cleaning position, which is fixedly installed at a fixed interval (alignment interval) below the rails 5a and 5b. Alignment base member 31a and portal cart 7
The lower part 31b is attached to the lower cross beam 7a on both sides, and the lower part 31b is moved down by the electric cylinder 31c to draw the portal cart 7 in the process of pinching the base member 31a, thereby aligning the riser cleaning position. It is designed to stop.

Numeral 32 is a rail sandwiching member for biting and fixing the portal cart 7 on the rails 5a and 5b, which is attached to the lower cross beam 7a on both sides of the portal cart 7 and has an electric cylinder 32a. The rail 5 moves down by the operation of the electric cylinder 32a.
Each of a and 5b is bitten.

When the riser 3 is to be cleaned, the portal carriage 7 is moved to the position of the riser 3 to be cleaned, and when stopped, the automatic alignment mechanism 31 is moved down to sandwich the base member 31a. In the process, the gate-shaped cart 7 is pulled in the pinching direction, and the vertical moving body 12 is directly opposed to the rising pipe 3.

Next, the motor 20 is operated to move the vertical moving body 12 downward together with the support frame member 13 so as to enter the rising pipe 3 from the lower conical cutter 27. The upper and lower conical cutters are rotating by the operation of the motor 25, and each disc sequentially descends into the ascending pipe to guide the upper disc 26a of the upper conical cutter 26 into the ascending pipe 3, and the upper disc 26a is moved. Until the lower end of the riser 3 is reached, the attached carbon is scraped off by a cutter attached to each disk to clean the riser 3 completely. At this time, the lower conical cutter 27
Reaches the lower end of the riser passage 1a leading to the riser 3 of the coke oven 1 and cleans the passage. After cleaning the riser 3, the vertical moving body 12 moves upward by the reverse operation of the motor 20 and is pulled out from the riser 3, and the gate-type cart 7 is moved to a position where the operation of the coke oven is not hindered. At this time, the rail sandwiching member 32 is actuated to grip the rails 5a and 5b, and to protect the apparatus from strong winds and the like together with the fall prevention hardware 35.

<Effects of the Invention> In the present invention, the conical cutter having a multi-stage and gradually narrower shape is inserted into the lower portion of the rotating inner cylinder constituting the vertical moving body as described above. Since the downward movement enters the riser, the approach is easy, and the lower stage that has entered sequentially guides the approach of the upper stage, so that there is an effect that both the riser and the cutter are not damaged. In addition, the multi-stage type of the conical cutter has the effect of increasing the downward stroke and preventing the cleaning unevenness in the riser pipe from being generated.
