FIG. 1 is a diagram showing an embodiment of the hot-furnace observing apparatus of the present invention, FIG. 2 is a diagram showing the state when the device is housed, and the same numbers as in FIG. 3 indicate the same contents. In the figure, 11 is a cooling water supply hose, 12 is a cooling drain hose, 13 is a cooling air hose, 14 is an upper boom, 15 is a lower boom, 16, 17 and 18 are hydraulic cylinders, 19 is a swivel base, 20 is a trackless vehicle, 21 is a monitor TV, and 22 is a cable.

In FIG. 1, a television camera case 1 having a built-in television camera has a support pipe 2 and a support pipe drive device 3 interposed therebetween.
Is driven to move up and down and rotate.

The TV camera 1 has a double cooling structure, and the cold water supply hose 11 and the cooling drain hose 12 are passed through the support pipe 2 to cool the inner periphery of the TV camera case 1 with cooling water.
The cooling air hose 13 is passed through the support pipe 2 to discharge the cooling air into the television camera case 1 to protect the television camera from high temperature.

Upper boom 14, lower boom 15, and hydraulic cylinders 16,17,18
The articulated boom composed of is loaded on the trackless vehicle 20 via the swivel base 19. The support pipe drive device 3 is tilted with respect to the upper boom 14 by the hydraulic cylinder 16 in the range of 60 ° to 170 °. The hydraulic cylinders 17 and 18 are respectively the upper boom 14
Also, the lower boom 15 is tilted, and the swivel base 19 swivels the entire articulated boom by a drive device (not shown).

Next, the case of observing the inner wall of the RH degassing tank will be described.

The trackless vehicle 20 accommodating the hot reactor observation apparatus of the present invention shown in FIG. 2 is stopped below the RH degassing tank 8, and hoses,
Connect the cables as specified. The control panel 6 is operated to operate the hydraulic cylinders 18, 17 and 16 by the control panel 6 so that the support pipe driving device 3 is in a vertical state directly below the RH snorkel 9. Next, the support pipe 2 is lifted to insert the TV camera case 1 into the furnace from the RH snorkel 9, and the support pipe 2 is rotated to take an image over a 360 ° range, and the situation is displayed on the monitor TV 21. And record it in the recorder as required. Further, as shown in FIG. 2, since the articulated boom can be folded, stored and moved, it is possible to promptly prepare for observation and move out after use.

In addition, 31 is a 1-step boom, 32 is a 2-step boom, 33 is an attachment part, 34 is a hydraulic cylinder, 35 is a support pipe holding part, and 36 is an outrigger.

The boom member of this embodiment comprises a two-stage slide boom, which is slidable to expand and contract, and is mounted on a swivel base 19 so that it can freely swivel 360 °.

The support pipe drive device 3 is connected to the two-stage boom 32 via the mounting portion 33.
The mounting portion 33 is attached to the tip of the support pipe driving device 3 with respect to the two-stage boom 32 by a remotely operated cylinder (not shown) or the like, and holds the angle.

Further, the hydraulic cylinder 34 adjusts and holds the angle of the first stage boom 31.

In the present embodiment, when observing the inner wall of the RH degassing tank, the trackless vehicle 20 is stopped below the RH degassing tank 8 as in the embodiment of FIG. Make a connection. Next, the operation panel 7 is operated, and the revolving base 19 is revolvingly driven by the control panel 6 by a drive device (not shown), and the hydraulic cylinder 34, the two-stage boom 32 and the mounting portion 33 are driven to slide and extend the boom. Support pipe drive device 3
So that is in a vertical position directly below the RH snorkel 9.
In this state, the support pipe 2 is raised to insert the TV camera case 1 into the furnace from the RH snorkel 9, and the support pipe is rotated for observation.

After the observation is completed, first, the support pipe 2 is lowered and the TV camera case 1 is taken out from the RH snorkel 9. Then, slide the slide boom to shorten it, disconnect the hoses and cables, raise the support pipe again and extend it, and set the mounting angle of the support pipe drive device 3 to the two-stage boom 32 so that the support pipe is almost parallel to the boom. Then, as shown in FIG. 4, the support pipe 3 is abutted and fixed to the support pipe holding portion 35. Alternatively, the support pipe 3 may be changed until the support pipe 3 becomes close to parallel to the boom, and then the support pipe 3 may be extended and then abutted on and fixed to the support pipe holding portion 35. In this way, the boom can be folded compactly and moved freely.

〔The invention's effect〕

As described above, the hot furnace observing apparatus of the present invention is freely movable, so that the time required for preparation and storage is shorter than that of the conventional handy type, and the furnace should originally have an observing apparatus. Therefore, the fixed observation device hindered the maintenance and operation of the furnace itself, but this point can be solved, and the target furnace is not limited to a specific furnace, and it can be easily heated. It is possible to observe inside the furnace.
