この考案は炉の吹付補修に用いる吹付機の吹付
ノズル駆動装置に関する。[Detailed Description of the Invention] This invention relates to a spray nozzle drive device for a spray machine used for spray repair of a furnace.
従来、RH炉、DH炉および転炉、取鍋等の熱間
吹付補修に用いる吹付機の吹付ノズル駆動装置は

ている。 As shown in FIG. 1, this spray nozzle drive device 1 includes a spray nozzle lifting roller 3 for holding and raising/lowering the spray nozzle 2, and a spray nozzle lifting/lowering drive motor 4 for driving the spray nozzle lifting roller 3. The attached rotary tube 5 is attached to the fixed pedestal 6
The spray nozzle (rotary tube) is rotated by a rotation drive motor 7 attached to the spray nozzle (rotary cylinder).

ーズな吹付補修を妨げていた。 Therefore, when the spray nozzle 2 is rotated, the spray nozzle lifting/lowering driving motor 4 attached to the rotary tube 5 also rotates in the same manner. However, there is a restriction that the power cable of the motor 4 for driving the spray nozzle up and down is broken if it rotates in one direction, and the disadvantage is that the spray nozzle 2 (rotating tube 5) cannot be rotated in one direction without limit. This prevented smooth spray repair.

つた。 Further, as a device for solving the above problem, there is a power supply method using a rotating brush. However, hot spray repair has the drawback of high production and maintenance costs because it deals with damage to insulating materials due to high temperatures and malfunctions due to dust.

点があつた。 Furthermore, the spray nozzle drive device is almost always installed directly above or below the container to be repaired, and is exposed to a high temperature atmosphere. Therefore, when the spray nozzle drive device 1 has a built-in drive motor, there is a drawback that strict heat protection measures are required, such as covering the drive motor with a heat insulating cover covered with a heat insulating material and cooling the inside with air.

一方向に無制限に回転することができる。 When the lifting motor 15 is stopped and the rotating motor 16 is started and rotated (forward and reverse rotation), the rotation is transmitted from the rotating bevel gear 20 to the inner rotating cylinder 22 via the rotating bevel gear 28, and the inner rotating cylinder 2
The shaft support frame 27 at the upper end of 2 rotates, and the spray nozzle lifting roller 25 is pivotally supported within the shaft support frame 27.
The spray nozzle 40, which is held movably up and down, can rotate in the same direction without limit.

ズル４０は回転する。 When the lifting motor 15 and the rotating motor 16 are started and rotated so that the outer rotating cylinder 21 and the inner rotating cylinder 22 have the same rotation speed, there is no relative movement between the lifting bevel gear 23 and the lifting bevel gear 30. Therefore, the elevating bevel gear 30 does not rotate. That is, the lifting gears 29 and 32 do not rotate, and as a result, the spray nozzle lifting roller 25 also does not rotate, and the spray nozzle 40 does not move up or down. but,
Since the inner rotating cylinder is rotating, the spray nozzle lifting roller 25 revolves, and the spray nozzle 40 held therein rotates.
外側回転筒２１と内側回転筒２２の回転数に差
があれば、昇降用ベベルギアー３０は自転する。
従つて吹付ノズル４０は回転しながら昇降するこ
とができる。 If there is a difference in the number of rotations between the outer rotating barrel 21 and the inner rotating barrel 22, the elevating bevel gear 30 rotates.
Therefore, the spray nozzle 40 can be moved up and down while rotating.
以上説明してきたごとく、この考案は
(1) 吹付ノズル昇降駆動モーターを非回転部に設
置しているため、吹付ノズルを一方向に無制限
に回転でき、スムーズな吹付補修ができる。 As explained above, this invention has the following advantages: (1) Since the spray nozzle lifting motor is installed in a non-rotating part, the spray nozzle can be rotated in one direction without restriction, allowing smooth spray repair.
(2) 回転ブラシを必要としないため、高温雰囲気
および粉塵に強く、メンテナンスコストがかか
らない。(2) Since it does not require a rotating brush, it is resistant to high temperature atmospheres and dust, and requires no maintenance costs.
