ら伸延し、炉内に進入する。As shown in FIG. 3, as a specific example, the shooting pipe 3 includes an outer pipe 3-1 and an inner pipe 3-2 slidably provided within the outer pipe and connected to a hose 8 at one end. It is configured. Note that the rotating support 1' of the receiving tube 2
Regarding the manner in which it is mounted on the top, 14 and 15 are first and second bearing parts that rotatably support the receiving tube 2, 16 is fixed to the upper end of the first bearing part 14, and is mounted on the rotating support 1'. This is the receiving pipe support pillar provided. Further, a cooling water chamber may be provided in the receiving pipe 2 or the shooting pipe 3.
For example, when the present invention is used, the gunning device is connected to the furnace body 12 during the traveling process of the trolley as shown in FIG.
Then, move the shooting pipe 3 in the axial direction of the furnace and turn the pendant 2 toggle trowel each wire feeding mechanism 4, 4', 4'', especially the feeding mechanism 4, 4' with a drive source.
If the outer tube 3-1 and the inner tube 3-
As shown in FIG. 5, the outer tube 3-1 is extended while maintaining the strength of the outer tube 3-1, and enters the furnace.

させる。At that time, as mentioned above, the three line feeders 4, 4' with drive sources can feed out each component pipe 3--, 3-2 independently, so the component pipes can be delivered extremely accurately and reliably. Furthermore, if necessary, it is also possible to operate only a desired outstanding mechanism with a drive source, for example, the steering mechanism 4, and leave the other line drawing mechanisms 4' with a drive source inoperative. . After that, the rotating mechanism 6 is driven to move all the constituent pipes 3-1 and 3-2 of the shooting pipe 3 to the receiving pipe 2.
At the same time, by driving the tilting mechanism 407, the spray nozzle 5 is exposed to the furnace repair section.

ものである。In this operation, all constituent pipes of the shooting pipe 3 are rotated as one through the receiver pipe 2, so that it is possible to prevent false twisting that occurs when each constituent pipe is rotated individually, and damage to the constituent pipes can be prevented. At the same time, the spray nozzle 5 can be more accurately aligned with the repaired part in the furnace.
Next, when the pendant switch 10 is operated to operate the electromagnetic valve of the tank 13 for storing slurry refractory material, the tongue opening/closing valve is released, and the refractory material is removed by the action of a water hose or air hose selected from wet or dry methods. is blown out from the spray nozzle 5 through the refractory material transportation hose 80, the outer tube 3-1, and the inner tube 3-2, and is applied to the repaired area.

る。Further, after the repair work is completed, the outer tube 3-1 and the inner tube 3-2, which are the constituent pipes of the shooting 3, are retracted toward the receiving tube 2 and returned to the original standby position. [Effects of the Invention] As described above, the present invention can achieve the following effects.
‘ィ} シューテイングパィプを多段線出構造としたの
で、旋回空間、進退空間を最小とすることができ、操作
性及び機動性を著しく高めることができる。Since the shooting pipe has a multistage line-out structure, the turning space and advancing/retreating space can be minimized, and operability and maneuverability can be significantly improved.
