Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a removal apparatus used for mechanically removing soot such as oxide floating on a melting surface of a metal melting furnace or adhering to a wall surface.
[0002]
[Prior art]
In a metal melting furnace, so-called soot such as metal oxide floats on the melting surface or adheres to the wall surface. Although it is necessary to remove such flaws for the purpose of maintaining the quality of the molten metal, in recent years, a device has been devised that mechanically performs the removal work that has been performed manually.
[0003]
The applicant of the present invention has also created and applied for such a removal device (Japanese Patent Laid-Open No. 7-120170).
Since this scissoring device can not only expand and contract the arm provided with the scraper plate but also turn and tilt, the scissors scattered in the metal melting furnace can be safely scraped and removed.
[0004]
[Problems to be solved by the invention]
However, in this conventional degreasing device, the scraping plate hits the wall surface particularly when removing wrinkles that adhere to the wall surface or float near the wall surface. It becomes.
However, since such a driving operation is extremely difficult, there is a problem that the removal work on the wall surface portion is not performed smoothly. In addition, there is a problem that the removal device is easily damaged by an impact when the scraping plate hits the wall surface.
[0005]
Accordingly, an object of the present invention is to provide a metal melting furnace removal apparatus that can easily remove the soot on the wall surface portion and does not break even if the scraper hits the wall surface. .

In an apparatus that removes soot that is tilted and stretched horizontally and floats on the melting surface (F) of the metal melting furnace (S) or adheres to the wall surface (W),
The turning of the arm part (7) is performed by transmitting the rotational force of the turning motor (4) to the arm part (7) via the chain (9), and the turning buffer spring (1) is applied to the chain (9). The shock absorbing spring (1) absorbs the impact when the scraping plate (8) provided in contact with the tip of the arm portion (7) hits the wall surface (W).
[0007]
The metal melting furnace removal apparatus according to claim 2 is configured such that the arm portion (7) is tilted via a rod (10) that moves forward / backward by the rotational force of the tilting motor (5). 10) is provided with a tilting buffer spring (2), and the tilting buffer spring (2) absorbs an impact when the scraper plate (8) provided at the tip of the arm portion (7) hits the wall surface (W). It is characterized by that.
[0008]
Furthermore, in the metal melting furnace removal apparatus according to claim 3, the arm portion (7) expands and contracts via a rack (12) that moves linearly with a pinion (11) that is rotated by an expansion motor (6). The telescopic motor (6) is fixed via the telescopic buffer spring (3), and the shock when the scraper (8) provided at the tip of the arm (7) hits the wall surface (W) is telescopic buffered. It is characterized by being absorbed by the spring (3).

Therefore, wrinkles on the wall surface portion can be more easily removed. At the same time, since the tilting buffer spring cushions the impact when the scraper hits the wall surface, it is possible to further prevent damage to the scissor removing device.
[0013]
Further, according to the invention described in claim 3, in addition to the function and effect of the invention described in claim 1 or 2, the arm portion is extended and contracted by the extension motor via the rack and the pinion, and the extension motor is extended and contracted. Since it was fixed via the buffer spring, the impact force received by the telescopic motor when the arm portion expands and contracts and the scraper hits the wall surface is absorbed by the telescopic buffer spring. Accordingly, the expansion / contraction operation is facilitated, and wrinkles on the wall surface portion can be further easily removed. In addition, since the telescopic shock absorbing spring absorbs the impact force, it is possible to more reliably prevent damage to the demolition device including the telescopic motor.

Therefore, wrinkles in the wall surface W can be easily removed, and damage to the dehairing device can be prevented.
[0022]
Subsequently, the telescopic motor 6 is operated to expand and contract the arm portion 7, and scrapes are collected with a scraping plate 8. When the scraping plate 8 abuts against the wall surface W in this expansion / contraction operation, the impact is transmitted to the expansion / contraction motor 6 via the pinion 11 and the rack 12, but the expansion / contraction motor 6 is applied to the holding portion 17 via the two expansion / contraction buffer springs 3. Since it is fixed, it is absorbed by the expansion / contraction buffer spring 3. Therefore, the expansion and contraction operation can be easily performed, and wrinkles in the wall surface W can be easily removed. Further, it is possible to prevent damage to the entire removal device including the telescopic motor 6, the pinion 11, the rack 12, and the like.
